Description

The present invention relates to a method for simultaneously producing a plurality of string-like reactive resin foam moldings using a sheet-like substrate.
More specifically, the sheet-like base material is aligned with a plurality of radial forming guides that converge in the traveling direction, the sheet-like base material width is narrowed in the traveling direction, and a deeper groove is continuously formed, and then aerated. The present invention relates to a method for simultaneously producing a plurality of string-like reactive resin foam moldings by discharging and filling the reactive foaming raw material, then closing the sheet-like substrate at the top of the groove, and reactively curing the reactive foaming raw material. It is.

  The present inventors have developed and filed a technique for continuously producing a string-like resin foam molded body in a plurality of rows (Patent Document 1, Patent Document 2). In this technique, a plurality of rows of radial molding guides that converge in the traveling direction are arranged along a sheet-like base material to form a plurality of rows of grooves, and a reactive resin foam raw material is discharged and filled into the grooves. A plurality of strings of reactive resin foamed molded articles are manufactured at a time. In the manufacturing method, the sheet-like base material is placed along a radial molding guide that converges in the advancing direction, the sheet-like base material is advanced to the vicinity of the convergence of the guide, and the reactive resin foaming raw material is filled in a plurality of rows of grooves. Further, the cord-shaped reactive resin foam molded body is manufactured by using a mold made of a sheet-like base material by closing the groove upper part of the sheet-like base material.

In this case, each of the plurality of rows of grooves converges toward the center of the sheet-like substrate width in the traveling direction along the radial forming guide. The sheet-like base material itself proceeds in parallel with the traveling direction of the sheet-like base material itself. Therefore, the groove near the center of the width direction of the sheet-like base material is almost parallel to the direction of travel, so it proceeds without bending. Since it changes in parallel to the line of the advancing direction of the sheet-like base material which connects up to winding up in a straight line, it is bent greatly. For this reason, bending increases as it goes to both ends of the sheet-like substrate width, and the reactive resin foam raw material that has been discharged and filled partially bends and moves around the upper part of the groove at the position where the sheet-like substrate advances in parallel. As a result, it has been found that there is a problem that some bubbles disappear.
In particular, as the number of rows to be manufactured increases, the opening angle of the radial forming guide increases, and the sheet-like base material on the side portion tends to bend, and the product at the width end portion of the sheet-like base material often becomes defective.

2 and 3 are a schematic top view and a side view showing a state in the production of a conventional string-like reactive resin foam molded article. FIG. 4 is a cross-sectional view at the position P6-P6 ′ in FIG. Reference numerals 22a, 22b, 22c, 22d, 22e, 22f, and 22g denote radial molding guides, and 30 ', 40', 50 ', 60', 70 ', 80', and 90 'denote parallel guide rails.
The sheet-like base material includes primary pressing jigs 31 ', 32', 33 ', 34', 35 ', 36' and secondary along radial forming guides 22a, 22b, 22c, 22d, 22e, 22f, 22g. It converges toward the convergence point 200 ′ while being pressed downward by the pressing jigs 41 ′, 42 ′, 43 ′, 44 ′, 45 ′, 46 ′.
The grooves 51 ′, 52 ′, 53 ′, 54 ′, 55 ′, and 56 ′ formed here are changed in the parallel direction at the refractive point 20 ′ of the groove. The filling liquid is filled at the application position 14 'of the reactive resin foam raw material in the groove, and the upper surface is closed and the groove of the sheet-like substrate is formed near the refractive point 20' of the groove as shown in FIGS. It bends so as to proceed in parallel, and the applied reactive resin foam raw material partially moves to cause defoaming and the like to form a non-uniform string-like reactive resin foam molding.
That is, in the conventional manufacturing method, all the grooves made of the sheet-like base material are formed along the radial forming guide converged at one point, and then proceed in parallel at a certain interval along the groove refraction position line. Therefore, it is inevitable that the filled reactive resin foam raw material is squeezed by the groove refraction position line 20 '.

As shown in FIG. 2, the opening angle β of the radial forming guide shown in FIG. 5 increases as the number of rows increases, and the bending angle of the side groove increases. Accordingly, the bending angle of the groove becomes large, and the reactive resin foam raw material has a large irregular partial movement, making it difficult to obtain a good product.
When an integrated product is to be manufactured by inserting another member at the time of manufacturing the string-like reactive resin foam molded body, it is necessary to insert the other member before the upper portion of the groove of the sheet-like substrate is closed. Regardless of whether the charging member is filled with the reactive resin foam raw material or after filling, the groove toward the converging point 200 ′ changes at a groove refracting position line 20 ′ that changes direction parallel to the traveling direction. When a member is bent or moved, bubbles are broken, and when the other member is a rigid body such as a roll shaft, it cannot be bent, so it cannot pass through the groove refraction position line, and is an integrated product. Has a problem that cannot be manufactured.
As shown in FIG. 6, the inserted roll shaft 16 having rigidity shifts from the radial forming guide to the parallel guide rail 6 but cannot pass through the groove bending position line 20 ′.

In addition, the string-like reactive resin foamed molded article has a great advantage that a plurality of rows can be molded simultaneously. On the other hand, particularly when the plurality of rows extend over 8 rows, the production line is frequently stopped. It is difficult to form all the string-like reactive resin foamed molded articles in an optimal state.
This is because it is difficult to make all the sizes of the grooves formed from the sheet-like base material exactly the same, and it is also difficult to make the weight of the liquid separation material to be injected exactly the same. Furthermore, since the size of the groove made from the sheet-like substrate and the amount of the injected raw material are subject to changes over time of the operation, it becomes more difficult to set the same manufacturing conditions.
Furthermore, in this manufacturing method, when the raw material is injected into the groove of the sheet-like base material, the injected raw material is not bubbled, reacted, or rate-determined. It becomes a circle. At this time, if the reactive resin foam raw material is excessive, the upper portion of the groove is closed, and then the raw material overflows between the two sheet-like base materials and the foam pressure is applied to the parallel guide rail. For this reason, there may be a problem that a large pressure is applied between the sheet-like base material and the parallel guide rail to stop the production line.

JP 2001-269949 A JP 2002-154123 A

An object of the present invention is to produce a larger number of strings of reactive resin foam moldings.
Specifically, the foaming reaction is not caused after the injection of the reactive resin raw material using a foaming agent, but the foaming pressure applied to the parallel guide rail is reduced by injecting the pre-bubbled reactive foaming raw material. In addition to preventing the line from stopping, the groove is not folded in the direction of travel after closing the upper part of the groove filled with the reactive foaming raw material, but is folded after filling the reactive foaming raw material and closing the upper part of the groove. There is no way to provide more products in multiple rows.
Another object of the present invention is to provide a string-like reactive resin-integrated foamed molded body in which other members are integrated.
Another object is to provide a string-like reactive resin foamed molded article having a high yield rate at the same time.

Claim 1 provides a method for continuously producing a string-like reactive resin foam molded body using a sheet-like base material that has been continuously drawn out.
Specifically, the sheet-like base material is continuously fed out, and the sheet-like base material on the radial molding guide is almost always radially arranged along a plurality of radial molding guides that converge the fed-out sheet-like base material in the traveling direction. As shown in FIG. 1, FIG. 7, and FIG. 8, the sheet-like base material is moved by the radial forming guide and the pressing jig while advancing on the forming guide and simultaneously reducing the distance between the radial forming guide and the radial forming guide. A step of creating a sheet-like base material in which a plurality of rows of grooves are formed in a three-dimensional manner by bending three-dimensionally into a shape, and then a single sheet-like substrate having the produced rows of grooves B step of moving the material to a substantially trapezoidal parallel guide rail (hereinafter referred to as a raised parallel guide rail) that is wide in the traveling direction of a plurality of rows and parallel to the traveling direction of the sheet-like base material before the upper portion of the groove is closed , Process A The reaction metered and transported using a pump into the multiple rows of grooves formed in the sheet-like base material from the time it descends until the upper part of the groove made of the sheet-like base material is closed on the raised parallel guide rail Step C for continuously discharging and filling the reactive foaming raw material introduced into the mechanical froth stirrer by introducing the functional resin raw material and the inert gas into the mechanical froth stirrer, and then proceeding further with the filled sheet-like substrate The present invention is in the production of a string-like reactive resin foamed molded article comprising a D process in which the upper part of the groove is closed with a raised parallel guide rail and then an E process in which the reactive foaming raw material is reactively cured.

In the present invention, the inert gas is refined into the raw material by a mechanical foaming stirrer called a mechanical floss stirrer rather than a method of foaming after discharging the raw material using a foaming agent called chemical foaming. Then, the reactive bubble forming raw material finely dispersed and bubbled is discharged and filled into the groove.
In the present invention, a foaming agent is added, and the raw material for foaming after discharging the raw material is referred to as foaming raw material, and the inert gas is refined and finely dispersed by a mechanical floss stirrer, so that bubbles are already generated at the time of discharging. The raw material that has been made into a material is referred to as an aerated raw material.
In the method of foaming by chemical foaming after introducing the foaming raw material into the groove, foaming pressure is applied, and under the overfilled raw material condition, the upper part of the groove is closed and then the raw material overflows from between the two sheet-like substrates. Since foaming pressure is applied to the parallel guide rails, there may be a problem that a large pressure is applied between the sheet-like base material and the parallel guide rails to stop the production line.
In the method of the present invention, the reactive bubble-forming raw material that has been bubbled is introduced into a groove formed of a sheet-like base material and cured by reaction. Therefore, the pressure applied to the parallel guide rails during molding is within the range of thermal expansion due to heating. There is no foaming pressure enough to stop the production line, and even under excessive raw material conditions, the production line does not stop due to excessive foaming pressure, allowing continuous operation for a long time.

An example of the production apparatus of the present invention will be described in detail.
1 is a schematic top view of the manufacturing apparatus, FIG. 7 is a side view of FIG. 1, FIG. 8 is a cross-sectional view of P1-P1 ′ of FIG. 1, 9 is a cross-sectional view of P2-P2 ′ of FIG. 1 is a cross-sectional view of P3-P3 ′, and FIG. 11 is a cross-sectional view of P4-P4 ′ of FIG. FIG. 5 is a schematic view of a radial forming guide.
FIG. 12 is a partially enlarged view of the vicinity of the application position in FIG.
FIG. 13 is a perspective view showing the relationship between the raised parallel guide rail and the reactive bubble forming raw material coating apparatus in FIG.
A specific example will be described with reference to FIGS.
The sheet-like substrate 2 is fed from the feeding roll 1 and proceeds along the radial forming guides 21a, 21b, 21c, 21d, 21e, 21f, and 21g. At this time, the upper surface of the sheet-like substrate 2 is pressed stepwise from the upper surface by the primary pressing jigs 31, 32, 33, 34, 35, 36 and the secondary pressing jigs 41, 42, 43, 44, 45, 46. Then, six grooves are formed in one sheet-like base material. The above is the A process. Here, the opening angle of the radial forming guide, that is, β shown in FIG. 5 is preferably 15 degrees or less. If it is 15 degrees or more, the sheet-like base material is wrinkled, which is not preferable.
Next, the sheet-like substrate 2 is wide in the advancing direction, and the sheet-like substrate is transferred to the raised parallel guide rails 61a, 61b, 61c, 61d, 61e, 61f, 61g parallel to the advancing direction of the sheet-like substrate. B process to be performed, and reactive foaming raw material is injected at the coating position line 14, and the sheet-like base material is further advanced, and the reactive bubbles are formed by the raised parallel guide rails 61a, 61b, 61c, 61d, 61e, 61f, 61g. The upper part of the groove filled with the gasifying raw material is automatically closed by the progress of the sheet-like substrate at the closing portions 71a, 71b, 71c, 71d, 71e, 71f, and then the reactive bubble forming raw material with the upper groove closed is parallel-guided It moves to the rails 30, 40, 50, 60, 70, 80, 90, and passes through an oven (not shown in the figure) and is cured by reaction.
When the raised parallel guide rail of the present invention is used, after filling the reactive foaming raw material, the groove is not bent and the sheet-like base material is linearly bent without closing even after the upper portion of the groove is closed. You can move to and proceed. Therefore, since the injected reactive foaming raw material is not broken by bending of a groove made from a sheet-like base material, it is a good product.
After step A, the reactive bubble forming raw material is discharged and filled on the parallel guide rail raised in step C, then the upper portion of the injected groove is closed in step D, and then the reactive bubble forming raw material is reacted and cured. Is the E step.
Next, when the sheet-like base material is a film or release paper having a releasability, the reaction-cured string-like reactive resin foam molded article 4 is formed by spreading the sheet-like base material with a take-up roll and winding it. The molded reactive resin foam can be automatically released at once.
The radially formed guide, the raised parallel guide rail, and the parallel guide rail are usually installed separately, but two to three points can be integrated, and this is also included in the scope of the present invention.
For example, the parallel guide rails can be integrated and installed before and after the raised parallel guide rails, and are included in the scope of the present invention. Further, the present invention can be accomplished by a method in which the parallel guide rail is installed in front of the raised parallel guide rail, and is included in the scope of the present invention.

In the production of the string-like reactive resin foamed molded article, the reaction may proceed only with the reactive catalyst, or the reaction may proceed by combining the reactive catalyst and heating. It is preferable to select appropriately considering the kind of the product, the kind of the target product or the productivity.
Although the heating oven is omitted in FIG. 1, the heating oven is usually installed after the raised parallel guide rail.

  The radial forming guide may be made of metal or plastic, and may be any material having rigidity. Also, the shape may be any material such as wire, square, plate, round bar, roll, belt, etc., and it may be a single or short product, or draw out its function by using multiple single items. May be.

In order to add another member to be integrated into the reactive resin foam molded article, either the A process or the B process may be used, but the B process is preferable. The reason is that when a rigid roll shaft or the like is introduced, the rigid member is not bent at the time of moving to the B process when it is introduced in the A process. In this case, either step A or step B may be used, and the input position of other members may be appropriately selected depending on the length, shape, rigidity, etc. of the input material.
The selection of whether the member is introduced before or after the reactive bubble forming raw material may be appropriately selected depending on the raw material blending prescription, the type of member, and the like.
In view of the difficulty of entraining bubbles, it is preferable that other members are charged after the raw materials are charged.

The groove closing mechanism will be described with reference to FIG. 1, FIG. 7, FIG. 8, and FIG.
The groove closing mechanism by the raised parallel guide rail is wide in the traveling direction of the sheet-like base material, and a plurality of substantially parallel raising guide rails 61a having a substantially trapezoidal shape whose center line is parallel to the traveling direction of the sheet-like base material, By placing the sheet-like base material along 61b, 61c, 61d, 61e, 61f, 61g, the width of the raised parallel guide rail becomes wider in the traveling direction. Therefore, the groove located at the lower part of the raised parallel guide rail is formed. This is done by closing the upper part of the sheet while pulling up both sides of the sheet-like substrate being formed. As a result, the sheet-like base material on the raised parallel guide rail is closed while taking up the slack, so that a uniform string-like reactive resin foam molded article can be manufactured.
When the width of the substantially trapezoidal guide of the raised parallel guide rail suddenly increases in the advancing direction, the upper part of the groove closes suddenly. Conversely, when the width gradually increases, the groove closes. Get slow.
The raised parallel guide rails are wide in the direction of travel, but are not necessarily linear, and may sometimes be complicated curves depending on the size and shape of other members to be integrated.
For example, it may be substantially parallel at the start point, widened at the intermediate point, and parallel at the end point.

  The size of the grooves created on the sheet-shaped substrate does not have to be the same, but it is created by combining several types of grooves according to the product type or size of the target product, and the string shape is different. It is also possible to produce a reactive resin foam molding at the same time. In such a case, it is preferable to install grooves of the same size symmetrically in the width direction of the sheet-like substrate. Otherwise, the left and right sheet-like base materials have different tensions, and the sheet-like base material is likely to meander to one side. Further, it is preferable that the positions at which the grooves are closed are all at the same time even when the sizes of the grooves in each row are different.

Next, the raised parallel guide rail of the present invention will be described in more detail.
12 is an enlarged top view in the vicinity of the raised parallel guide rail portion of FIG. 1, and FIG. 13 is a perspective view showing the relationship between the raised parallel guide rail and the reactive bubble forming raw material coating apparatus.
As shown in FIG. 12, the grooves 51, 52, which are formed by the radial forming guides 21a, 21b, 21c, 21d, 21e, 21f, 21g and the secondary pressing jigs 41, 42, 43, 44, 45, 46, 53, 54, 55, and 56 are directed toward the convergence point 200, but are bent in a direction parallel to the traveling direction of the sheet-like substrate itself at the groove bending position line 20, and travel along the raised parallel guide rail. To do.
As shown in FIGS. 12 and 13, the raised parallel guide rails 61a, 61b, 61c, 61d, 61e, 61f, 61g have a substantially trapezoidal shape extending in the traveling direction, and the sheet-like base material is raised parallel guides. As the rails 61a, 61b, 61c, 61d, 61e, 61f, and 61g progress, the width of the raised parallel guide rail gradually increases, so that both ends of each groove of the sheet-like base material 2 under the raised parallel guide rail are pulled up. The groove is closed by its own sheet-like substrate 2. The application position 14 of the discharged reactive bubble forming raw material is already after the position bent at the groove refracting position line 20 and proceeds without being bent after the discharge filling, so that the groove does not bend and therefore receives ironing. A good string-like reactive resin foam molded article can be obtained without any problems.

The raised parallel guide rail may be composed of a single trapezoidal shape or may be composed of several members. If the action is trapezoidal, it is included in the scope of the present invention.
That is, the process of closing the groove with the raised parallel guide rail is included in the scope of the present invention if it has substantially the same function as the trapezoid.

  According to the second aspect of the present invention, the reactive resin material and the inert gas are bubbled with a mechanical floss stirrer in carrying out the present invention, and an oak mixer type stirrer is particularly preferable. In the agitator of the Oaks mixer type, the stirrer is surely stacked by the stator and the rotor so that the number of stirring stages to the first stage stirring blade and the next stirring blade is stacked, so there is no insufficient partial bubble dispersion, and partial coarse bubbles and pinholes A reactive resin foam with no fine bubbles is obtained. The Hobart mixer type agitator applies strong shearing by two rotor blades rotating in the opposite direction. However, the flow of the reaction liquid is not constant and uneven stirring occurs, compared to the Oaks mixer type agitator. Is also inferior.

Here, the mechanical froth stirrer is different from the normal polyurethane foam stirrer for chemical foaming using CO ₂ gas generated by the reaction of water and polyisocyanate as a foaming agent, and reactive with inert gas. This is a mixing machine that forcibly mechanically mixes with the resin raw material and refines the inert gas with a strong stirring shear force to form bubbles before the reactive resin raw material determines the reaction. The machine is an Oaks mixer or Hobart mixer.

An Oaks mixer type stirrer as a mechanical floss stirrer will be described in detail with reference to FIGS. 14, 15, 16, and 17. FIG.
FIG. 14 is a schematic view of a reactive resin foam continuous production apparatus comprising a mechanical floss coat hanger type die in which a mechanical floss stirrer and a coat hanger type die of the present invention are directly connected.
In FIG. 14, reference numeral 101 denotes a reactive resin foam continuous production apparatus comprising a mechanical floss coat hanger type die. In general, it comprises an oak mixer 103, a coat hanger die 5, and a motor 102 for rotating the oak mixer.
The reactive resin raw material components sent from the metering pump are introduced into the Oaks mixer 103 through the reactive resin raw material component inlets 131, 132 and 133, and the inert gas is introduced into the Oaks mixer 103 through the inert gas inlet port 134. The mixture is stirred and mixed, flows into the separation coat hanger die 5, and is separated and discharged from the die outlet 13.

FIG. 15 is a cross-sectional view of the mechanical floss stirrer 103. FIG. 16 is an enlarged view of the circle in FIG. 17 is a cross-sectional view taken along line AA ′ of FIG.
The reactive resin raw material components and the inert gas are introduced from the reactive resin raw material component inlets 131, 132, 133 and the inert gas inlet 134, and flow into the upper gap between the upper stator 135 and the rotor 136 of the Oaks mixer 103. The rotor 136 reaches the side of the rotor 136 while being agitated by the blades of the rotor 136, then flows to the lower surface, gathers at the center through the lower gap between the lower stator 137 and the rotor 136, and is discharged from the Oaks mixer outlet 138. .

Here, as shown in FIG. 17, the rotor 136 is composed of a rotor blade 1361 that is a protrusion and a rotor cavity 1362 that does not have a blade. The top stator is also composed of similar upper stator blades 1351 and a cavity 1352.
In FIG. 17, the reactive resin raw material component and the inert gas flow from the central part to the side part, but the upper stator blade 1351 of the upper stator 135 and the rotor blade 1361 of the rotor 136 are sheared by the rotation of the rotor 136. While receiving, the raw material moves to the side from the upper stator cavity 1351 and the rotor cavity 1362. The raw material that has reached the side moves to the lower stage, is similarly sheared by the rotation of the rotor, gathers at the lower stage center, and is discharged from the Oaks mixer outlet 138.
Since a normal polyurethane foaming stirrer has only rotating blades, the whole liquid can be stirred evenly in a macro manner, but the inert gas cannot be uniformly finely divided or uniformly finely dispersed. That is, uniform fine division and insufficient fine dispersion occur, and the bubble diameter is large.

As the inert gas used in the present invention, there are air, N ₂ gas, argon gas, helium gas, CO ₂ gas and the like, and N ₂ gas is preferable in that the bubbles become fine.
Air is preferable in terms of cost, but it is good when the pressure inside the Oaks mixer is 0.3 MPa or less, but when it exceeds 0.3 MPa, it is difficult to dehumidify the air and it is difficult to handle it as dry air, and polyisocyanate is used. It is not preferable in the polyurethane resin foam.
Is preferably in the range of 50cm ³ ~1400cm ³ on the reaction resin material 100 parts by weight as the amount of the inert gas.

According to a third aspect of the present invention, the method of continuously discharging the reactive foaming raw material into the plurality of rows of grooves formed from the sheet-like base material on the raised parallel guide rail in the step B of the first aspect is based on a specific condition. By using a liquid coat hanger die.
The separation coat hanger type die has an opening angle θ of the manifold at the raw material introduction port in the range of 120 ° to 145 °, and the ratio of the die internal volume excluding the manifold to the manifold volume is 1: 0.1 to 0.1. A separation coat hanger type die that is in the range of 1: 0.7 and in which a liquid divider is installed in parallel with the line connecting the raw material introduction port and the die exit to the die lip at the shortest distance is used. Reactive bubbling raw material is continuously introduced into the raw material inlet of the hanger type die, thinned by die land and liquefied to flow at almost the same speed, and the thinned raw material is separated into a plurality of parts by the liquid divider. , A liquid separation coat hanger type die for discharging the liquid separation from each die outlet into a plurality of rows of grooves.

When discharging and filling a plurality of rows of grooves, if there are ten rows of grooves formed using a radial forming guide, ten mechanical floss stirrers need to be prepared.
By using the separation coat hanger type die, the reactive foaming raw material discharged from one mechanical floss stirrer is simply introduced into the separation coat hanger type die and separated into the required number for running. What is necessary is just to drop-fill the above-mentioned plurality of grooves by gravity from above.

The separation coat hanger type die having specific conditions used in the present invention will be described in more detail.
FIG. 18 is an open perspective view of a conventional liquid separation coat hanger type die 5 comprising two coat hanger constituting plates 5a and 5b.
The reactive bubble forming raw material introduced from the raw material inlet 19 flows into the manifold 7 and then into the die land 12 to form a thin film that flows at a constant speed. Here, the die land 12 indicates a portion from the lower edge of the manifold 7 toward the lower end of the flow rate adjusting plate 8 toward the die outlet 13, that is, the upper end of the die lip 11. The thinned reactive foaming raw material is discharged from the die outlet 13 through the die land 12 as a liquid discharge amount by the liquid dividers 91, 92, 93, 94, 95, 96, 97 installed on the die lip 11. The grooves formed from the sheet-like base material are continuously discharged and filled.
The intervals of the liquid dividers do not have to be the same, but it is preferable to install them so as to balance the die in the width direction.
The flow rate at each position is adjusted by pushing and pulling the flow rate adjusting bolt 10 at each position connected to the flow rate adjusting plate 8 to widen or narrow the die land gap t.
Further, when the flow rate at the end in the die width direction decreases during continuous operation for a long time, the flow rate adjusting bolts 10a and 10f are rotated to widen the die land gap and make the flow rate uniform.

A fourth aspect of the present invention is that the flow rate adjusting plate is installed on the liquid separation coat hanger type die, and the flow rate adjusting plate is a divided flow rate adjusting plate divided into a plurality of directions in a direction perpendicular to the die width. By dividing, the height of the flow rate adjusting plate can be freely changed at each position to adjust the flow rate of the reactive bubble forming raw material. By using this divided flow rate adjusting plate, the flow rate at each position in the die width direction can be adjusted, and the flow rate due to the gelation of the reactive foaming raw material at the end in the die width direction during continuous operation for a long time. It is possible to adjust independently of the decrease, and the flow rate can be increased to enable continuous operation for a long time.
Normally, the liquid separation ratio at each liquid separation position is determined by the arrangement interval length of the liquid divider, but even if the arrangement interval length is set to an equal interval, the liquid separation ratio can be obtained only by adjusting the height of the divided flow adjustment plate. Can be changed to about 1: 1 to 1: 3, preferably about 1: 2.

The number of divisions of the divided flow rate adjusting plate is preferably an integer multiple of the number of liquid divisions by the liquid partitioning tool.
The integer multiple is 1 × 2 × 3 × 4 × 5 times or more, preferably 1 × to 2 ×. Increasing the factor by a factor of 3 or more does not significantly improve the effect.
By making the divided flow rate adjusting plate an integer multiple, the divided position flow rate at the target position can be increased or decreased, and the influence on other adjacent divided positions can be minimized.

FIG. 19 is an open perspective view of another divided liquid coat hanger die used in the present invention.
20 is an enlarged view of the divided flow rate adjusting plate of FIG. 19, and FIG. 21 is a sectional view of the die of FIG.
In the conventional type liquid separation coat hanger type die of FIG. 18, when adjusting the flow rate at each position, the flow rate adjusting bolt 10 connected to the flow rate adjusting plate 8 is turned to bend the flow rate adjusting plate 8 to adjust the gap between the die lands. The flow rate was adjusted.
Since this method bends a single plate, for example, it is not easy to pull a bolt next to a pressed bolt, and fine adjustment is impossible.
In another divided liquid separation coat hanger type die shown in FIG. 19, the flow rate adjusting plate 8 ′ is divided into 81 ′, 82 ′, 83 ′, 84 ′, 85 ′, 86 ′ in the direction perpendicular to the die width direction. Therefore, the height of the divided flow rate adjusting plate at each position can be adjusted independently regardless of the adjacent position, and the flow rate can be adjusted freely.
The larger the number of divisions of the divided flow rate adjusting plate, the easier it is to adjust, but an integer multiple of the number to be manufactured is preferable. That is, in the six division of this example, the number of manufactured is preferably 3 or 6. As a result, the flow rate at each position can be freely adjusted while reducing the influence on other positions.

A fifth aspect of the present invention is that the sheet-like substrate according to the first aspect is a film or a release paper having releasability.
The fact that the sheet-like substrate is a film or release paper having releasability means that a mold die composed of a plurality of sheet-like substrates is prepared using this sheet-like substrate, and a string-like reactive resin foam molded article is formed. Not only can be produced, but also a mold made of a sheet-like base material can be easily opened to take out the string-like reactive resin foam molded article.
This will be specifically described with reference to the drawings.
1 and 8 to 11, the sheet-like substrate 2 fed from the feeding roll 1 is formed with radial forming guides 21a, 21b, 21c, 21d, 21e, 21f, 21g as shown in FIG. Grooves 51, 52, 53, 54, 55, 56 are formed by the primary pressing jigs 31, 32, 33, 34, 35, 36 and the secondary pressing jigs 41, 42, 43, 44, 45, 46, The reactive foaming raw material 15 is discharged and filled in the groove at the application position, and the string-like reactive resin foam molded body 4 is formed in the groove of the sheet-like substrate 2 as shown in FIG.
Next, the sheet-like base material 2 is spread and taken up by the take-up roll 3 so that the string-like reactive resin foam molded article 4 is automatically peeled off. As shown in FIG. The string-like reactive resin foam molding is taken out in a completely peeled state. On the other hand, when the sheet-like substrate has adhesiveness, the product is an integrated product of the string-like reactive resin foamed molded article and the sheet-like substrate.
The production of the string-like reactive resin-integrated foamed molded body will be specifically described with reference to FIGS.

  In FIG. 22, FIG. 23 and FIG. 24, the reactive foaming raw material is filled in a plurality of grooves made of a sheet-like base material, and the upper part of the grooves is closed, and the sheet-like base having releasability until reaction hardening occurs. Although it is the same as the case where a material is used, after hardening, the sheet-like base material 2 is taken up by the nip roll 18 while being spread. At the stage of take-up, a plurality of string-like reactive resin integrated foam-molded products are commercialized in a shape hanging on the sheet-like substrate 2 as shown in FIG. These products are handled as string-like reactive resin-integrated foamed molded articles 4 ″ with the sheet-like base material by removing unnecessary sheet-like base materials.

The sixth aspect of the present invention is that the string-like reactive resin foam molded body is a string-like reactive resin foam roll precursor. Here, the precursor refers to a state one step before becoming a roll, and has a shape as shown in FIG. Usually, the string-like reactive resin foam roll precursor is made into a product by cutting the surface.
The manufacturing method will be specifically described with reference to FIGS. 1, 25, 26, 27, and 28.
In FIG. 1, the sheet-like base material 2 having releasability is fed out from the feeding roll 1, and the primary pressing jig 31 is supported by the radial molding guides 21a, 21b, 21c, 21d, 21e, 21f, 21g. 32, 33, 34, 35, 36 and secondary pressing jigs 41, 42, 43, 44, 45, 46 are pressed to create grooves 51, 52, 53, 54, 55, 56. Next, it moved to the raised parallel guide rails 61a, 61b, 61c, 61d, 61e, 61f, 61g, and the reactive bubble forming raw material was discharged and filled at the application position 14 on the raised parallel guide rails as shown in FIG. 28, a roll shaft 16 with bearing caps 17 made of silicon resin set at both ends is inserted later, or a roll shaft 16 with bearing caps 17 made of silicon resin set at both ends as shown in FIG. After charging, the reactive foaming raw material is discharged and filled, the upper part of the groove is closed by advancing the sheet-like base material, the reactive foaming raw material is reacted and cured, and then the sheet-like base material is spread and wound up Demolding to produce a string-like reactive resin foam roll precursor 4 ′. In the latter, the reactive foaming raw material is always discharged and filled on the roll shaft at the center of the roll shaft. However, the reactive foaming raw material moves to the left and right of the roll axis and the coating is displaced, so that bubbles are involved in the foam. In many cases, there are more defective products than the former.

The seventh aspect of the present invention is that the polyurethane resin foam or the silicon resin foam is the most suitable production method for carrying out the string-like reactive resin foam molded article of the present invention.
Originally, the present invention can be applied to any reactive resin foam molding, and in addition to polyurethane resin foam and silicon resin foam, polyacrylic resin foam, epoxy resin foam, melamine resin foam, phenol resin foam Body, urea resin foam, etc., but polyurethane resin foam or silicon resin foam is most suitable depending on raw material viscosity, reaction rate, durability of the obtained product, physical strength and the like.
In the case of a silicon resin foam, as in the case of a reactive polyurethane resin foaming raw material, a one-component or two-component reactive silicon resin foaming raw material is introduced into a liquid-separation coat hanger type die under specific conditions used in the present invention. And a string-like silicon resin roll precursor can be manufactured by discharging and filling a reactive bubble-forming raw material into a groove formed at the raised parallel guide rail position.

In the present invention, after a plurality of grooves are formed on a sheet-like base material via a radial forming guide, before the grooves are closed, the plurality of rows are wide in the traveling direction and parallel to the traveling direction of the sheet-like base material. A reactive foam material was discharged along a raised parallel guide rail and discharged into a plurality of rows of grooves on the raised parallel guide rail, and further reacted and cured to discharge a reactive resin material as in the conventional method. Then, it is the manufacturing method of the string-like reactive resin foaming molding by which the filled groove | channel is not bent and a reactive resin raw material is not squeezed.
As a result, the bubbles located on the side of the sheet-like substrate are not defoamed or hollowed out, the quality is stabilized, and the yield rate is improved. At the same time, not only the yield rate of products located on the side of the sheet-like base material is improved, but the number of products that can be manufactured at one time is improved, so that the cost can be significantly reduced. Further, a string-like reactive resin-integrated foamed molded article can be produced by introducing a rigid member.
In addition, since the aerated reactive foaming raw material is introduced into a groove formed of a sheet-like base material and reacted and cured, the pressure applied to the parallel guide rail during molding is in the range of thermal expansion due to heating, even under excessive raw material conditions. The foaming pressure is not high enough to stop the production line, and the continuous operation is possible for a long time without stopping the production line due to excessive foaming pressure as in the case of using chemical foaming.
Furthermore, since the insert member integrated with the string-like reactive resin foam molded body absorbs heat at the time of foaming, the surface portion of the insert member may not be bubbled in a normal chemical foaming, but may become a thick skin. In the mechanical floss foaming of the reactive resin raw material and the inert gas of the present invention, the surface portion of the insertion member is also a product having a uniform density.

  In the present invention, a sheet-like base material is placed along a radial forming guide, and a plurality of continuous presses in the traveling direction are pressed by a pressing jig through the radial forming guide while reducing the interval between the radial forming guide and the radial forming guide. A sheet-like base material having a groove is prepared, and the sheet-like base material is widened in a plurality of rows in the traveling direction before the groove upper portion is closed, and parallel to the traveling direction of the sheet-like base material. It is moved to the guide rail, and the reactive bubble forming raw material is discharged and filled into each groove on the raised parallel guide rail, and then reaction hardened.

The distance between the radial molding guide and the radial molding guide at the start of the sheet-shaped substrate is the target circumferential length of the string-like reactive resin foam molded product and the parallel guide at the position where the product is reactively cured. The length is preferably the sum of the width and thickness of the rail plus twice the thickness.
The raised parallel guide rails that are wide in the traveling direction of the plurality of rows and whose center line in the width direction of the sheet-like base material is parallel to the traveling direction finally come into contact with each other, but the gap of 50 μm to 1000 μm It is preferable to use parallel guide rails having the same width after the point of time.
In the description of the present invention, the heating oven for curing the reactive resin foam molded article has not been sufficiently described, but the temperature of the heating oven is preferably 90 ° C to 130 ° C.

The degree to which the upper part of the formed groove is closed can be set by changing the distance between each raised parallel guide rail and each raised parallel guide rail in the closed part. In this case, the upper part of the string-shaped reactive resin foamed molded product becomes an open product, and when the interval is narrow, a so-called parting line that can be formed at the joint between the left and right sheet-like base materials may occur.
This interval is usually preferably in the range of 50 μm to 1000 μm. More preferably, it is the range of 100 micrometers-550 micrometers.
The obtained string-like reactive resin foam molding is used for air sealing materials, water sealing materials, electromagnetic sealing materials, earplugs, rolls and the like.

  The sheet-like substrate used in the present invention may be any sheet-like substrate as long as it can be applied, and may be a film or paper, a composite of film and paper, or a sheet. When producing a single string-like reactive resin foam molded article, a sheet-like base material having releasability may be selected, and when a sheet-like base material and a composite product are desired, the releasability is low. It is only necessary to select paper, woven fabric, nonwoven fabric, or a film having adhesiveness that has no adhesiveness.
