Description

[Detailed Description of the Invention] This invention can be used by being attached to a corner of a staircase.
＼It relates to the second material and its extrusion molding method, and in particular, it has a tread part that is fixed to the tread of the stairway and a riser surface that is fixed to the riser surface of the stairway. The entire metal base is formed into a metal base, and its surface is integrally shaped by extrusion molding.
The present invention relates to an anti-slip material comprising a slip layer and a slip layer made of soft synthetic resin to be adhered, and an extrusion molding method thereof.

Anti-slip materials installed at the corners of stairs are
It has an anti-slip function that actively prevents slipping on stair treads, and a buffer protection function in the event of an unexpected accident such as falling or stumbling on stairs, especially at the corners. It is required that it be able to be firmly attached to the corner of the stairs.

Therefore, the conventional sill/stopper has a metal base with a tread section 2 and a riser section, and has a cross section shaped like a cross section. -\Lay a layer on the first layer,
In addition to fixing the 2 treads to the treads of the stairs and a part of the 10 kicks to the top surface of the stairs to protect the corners of the stairs, the Nizu-t is used, which has the anti-slip function and the buffer protection function.

As a method for producing such a non-slip material, there is a method in which a second layer made of 0-heavy synthetic resin is pre-formed on the whole metal unit and is bonded with an adhesive, and a non-slip material is manufactured using an adhesive. A method is used in which a layer is bonded to the surface of the entire unit by press molding.

However, in such a method, the adhesive strength between the entire platform and the anti-slip layer may be insufficient, or
Because it is press-formed, the equipment becomes large, and this molding equipment can only produce anti-slip materials of specified dimensions, so products of various lengths are available depending on the width of the staircase. There are problems with the required anti-slip materials, such as poor yields and high manufacturing costs.

As a manufacturing method that solves these problems, the entire machine is inserted into the mold 219 of the extruder, and the edge/stick layer inside this mold is shaped and bonded by extrusion molding. Conceivable.

However, in this method, when the molten resin for forming the anti-skid layer is discharged onto the adhesive area on the surface side of all the machines in the mold, the discharge pressure from this molten resin is generated and all the machines are The back side (flll) is strongly pressed against the bottom wall of the all-machine passage formed in the mold, and it rubs against the bottom wall of this all-machine passage, causing damage and deformation of the whole machine itself. The molding speed at which the table passes through the mold is not constant, and the surface of the anti-slip layer that is shaped and adhered to the surface of all the tables may become rough, or stripes may appear on this surface.・The problem arises that the product value of the anti-stick material is significantly impaired, and
Strong friction sometimes caused J20 seizure.

In addition, when manufacturing anti-slip materials by extrusion molding, the anti-slip layer is made of soft vinyl chloride resin (another problem is that metals and soft synthetic resin generally tend to have poor adhesion). When using this product, the plasticizer contained in this soft resin increases the strength of the adhesive, making it possible to firmly bond the area on the non-slip layer of all machines.
L <, There is a non-slip layer from the metal base for single-layer applications, which will frequently be subjected to tread pressure during use! II may be released.

Therefore, in order to solve this problem, we developed a passion for creating strong adhesives between metal and soft synthetic resin.
If you use a green adhesive like this one, you can apply it to the extrusion molding of the A-beam material. It is necessary to heat it to about 250℃ and heat it for 4 degrees, and all the machines themselves are heated to this temperature and then heated.
Additionally, there was a problem that +LJ was easily damaged.

Furthermore, in this method, all the units that pass 1 Jfl through the mold are made of metal, so the tolerances of all the units are absorbed and the unit passes smoothly five times through the mold. Therefore, it is necessary to take a certain space between the passages of all machines and the passageways of all machines. Resin 1?Z)-4 When shaping and bonding the edge prevention layer, discharge pressure from the molten resin is generated on the entire surface of the table and flows in the above-mentioned gap, resulting in the shaping area, that is, the bonding area on the side of the whole table. The 171 pieces of burrs form on the outside of the product, significantly damaging the appearance of the hem-preventing material before it becomes a product, and the deburring work required to remove these burrs is manual labor, which is extremely complicated, reducing the overall manufacturing cost. It can also lead to a decrease in the number of children.

In view of this point of view, the present invention applies a palm active adhesive to the adhesive area on which the anti-slip layer is formed on the surface side of all the machines, and inserts the machines into a processing device. While maintaining the activation of the adhesive with a car until the adhesive reaches its thermal activation temperature, all the above units are introduced into the mold. A molten soft synthetic resin is applied to the side adhesion area and forms a secondary hemlock layer on the activated adhesive. A molten soft synthetic resin that forms a non-adhesive mold release film is discharged approximately corresponding to the above, and an anti-stick layer is formed and adhered to the front side of all of the above-mentioned units, and the back side of all of the units is A non-adhesive release film is formed on the side so that it adheres to the surface (=1), thereby solving the above-mentioned problem and creating a strong anti-slip layer on the surface of all units. It is possible to manufacture the 1" and 2nd shrines by extrusion molding.

In addition, resin partitions that match the width of the second layer and extend in the longitudinal direction are installed on both the front and back edges of the slide bonded to the front surface of the entire board (J). On the side of the mold through which the stand passes, there is provided a cutout (1) 1 that matches the fat partition section described in -F-, and these partition pieces and the resin partition section work together.
2. The surface of the entire stand is shaped to prevent the molten resin from flowing out at both the front and rear edges of the anti-stick layer. 1) Provides a non-slip mill without burrs on both front and rear edges of the layer and an extrusion molding method thereof.

11j (The area to be shaped is not limited to this, for example, as shown in FIG. As shown in FIG. 12, it may be extended by the front and back sides of part of the kick 1 + 54 of the entire stand (1).

Furthermore, in the above embodiment, as shown in FIG. 5, the melt () 51 is used to prevent the melt from being discharged onto both the front and back surfaces of the entire mold (12). , the molten resin for the non-adhesive release film (3) is 1-
At the position where one foot matches the metal base, all the bases (1) are not at the same position in the advancing direction, and the respective discharge pressures of the molten resin forming the anti-slip layer (2) act in opposite directions at the same position. As a result, the entire unit (1) heated to the heat activation temperature of the heat-activated adhesive may be deformed, or may be pressed against the bottom wall of the passageway (16) and burned or damaged. There are no more things to do.

However, regarding the position where each of these molten resins coincides with the front and back surfaces of the entire stand (1), it is necessary to consider the resin pressure, discharge pressure, viscosity, etc. of each molten resin and to appropriately space them from each other.

As shown below, the anti-slip material of the present invention has an anti-slip layer integrally formed on the front and back sides of all the tables, and an anti-slip layer on the back side. Approximately corresponding to 9
11M non-adhesive mold release film (= 1) is attached, so when packing and shipping IJJ number su・＼stop shrine, it is formed from soft synthetic 1i-1 resin. te f
LJff Easy Izu-\Riyume layer does not come into direct contact with the back side of all units, and when shipped, the layer is 1.
Shizuro Yoko Shichi is missing.

Also, according to the extrusion molding method of the invention, the slider II: and the inner layer are bonded to the entire board and its surface. It is firmly attached by the mold adhesive, and even if all the machines are heated to high temperatures due to the use of this heat-activated adhesive, the non-adhesive material is shaped and adhered to the back side of all the machines during molding. Because the mold release film prevents all the molds from being strongly pressed against the wall of the passageway of the mold, all the molds are not deformed or damaged, and all the molds can pass through the mold. The speed is also constant, and the surface of the anti-slip layer formed and adhered to the entire surface of the machine will not be roughened or a striped pattern will occur on this surface.

Furthermore, on the front side of all the tables that enter the mold, there is a longitudinal direction on the front edge side and the rear edge side, respectively, in accordance with the width dimension of the anti-slip layer that is shaped and bonded to the surface. A resin partition section extending from the lower end of the side wall that partitions the front edge and rear edge of the anti-slip layer is provided in the mold through which all the units pass, and a section protrudes northward of the resin partition section 2 from the lower end of the side wall that partitions the front edge and rear edge of the anti-slip layer. A partition piece that matches the resin partition part is provided, and these resin partition part upper partition pieces prevent the molten resin from flowing out at both rear edges of the layer 11f, which is not shaped on the surface of the entire unit. 11
- Therefore, when forming and bonding the anti-skid layer on the second adhesive area of the whole machine surface in the mold, the molten resin discharged onto the whole machine surface will be applied to the whole machine surface. The resin does not flow out of the adhesive area beyond the resin partition, prevents waste of the beam in the anti-slip material, does not damage the appearance of the second material, and removes this beam. This eliminates the need for tedious work and greatly reduces the manufacturing cost of anti-slip materials.
