関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a foaming material mainly used as a sound absorbing material such as a sound absorbing material inserted between a floor material and concrete, or a sound absorbing material for partitioning a room. The present invention relates to a method for manufacturing a plate material using.

理を経て製造されていた。Conventionally, a plate material using a foamed material such as foamed polyethylene has been manufactured through a post-treatment in which the foamed material is subjected to uneven processing by hot pressing and then bonded to a base material (heterogeneous material) such as a plywood board (plywood).

ストが嵩むといった問題がある。When a plate material is used as a sound absorbing material, it is effective to form a foam material on both sides in order to enhance the sound absorbing effect. However, in such a case, the adhesive area with the base material is reduced and the adhesive force is reduced. In order to sufficiently secure the adhesive force, it is necessary to pressurize at the time of bonding and maintain the state for several minutes to several hours, and in some cases, it is necessary to heat to accelerate the naturalization of the solvent. Not only is it complicated, but processing time and processing cost increase.

題を解決した。The present invention is a method for producing a molded plate material by simultaneously molding a foamed material and heating / pressurizing the foamed material to a plywood or a compressed urethane substrate, wherein the foamed material and the substrate are temporarily bonded. Then, the foam material is pressed against a mold attached to one of the upper and lower hot plates of the heat press for thermoforming, and the convex contact portion of the mold in the foam material is in a completed state, and The above problem is solved by a method for manufacturing a plate material using a foam material, wherein the foam contact material is released from the foam contact material when the convex contact portion of the mold is in an unfinished state.

接触面においては、加圧と適当な加熱によって溶剤が気
化し、短時間の内に接着が完了する。Both the adhesive surfaces of the base material made of foam material and hard material such as plywood or soft material such as compressed urethane were applied to one or both sides, solvent-based adhesive was applied, and both were temporarily adhered, and then mounted on a hot press. When the foam material side is brought into contact with the mold surface and pressed, the foam material is molded by the mold. At that time, at the contact surface between the foam material and the base material, the solvent is vaporized by pressurization and appropriate heating, and the adhesion is completed within a short time.

じ、以下のような現象が生ずる。Also, during molding, before the entire foamed material is in a molding completed state (dead burn), that is, the convex contact portion of the mold is in a completed state, but the concave contact portion of the mold is incomplete. When the mold is released in the state, the following phenomenon occurs depending on the hardness and softness of the base material on the hot plate side.

紋様となり、吸音性に優れた一体成形品が作られる。(a) In the case of foamed material and hard material (plywood, etc.) If this combination is taken out before the thermoforming completion state, the non-crushed part, that is, the concave part of the mold is in the unformed state (light burn), The activity remains as repulsive elasticity, while the area around the convex part of the mold is in a dead burn (molding completed) state, so the internal activity that originally remains with release causes the back surface (non-mold surface). Try to escape to.
However, since there is a hard material on the back surface, most of the residual activity escapes to the front surface, and further bulge occurs at the bottom of the convex shape made by the mold, and the lower bulge that is one size larger than the convex shape made by the mold prototype. And a complex pattern of two-step protrusions, which are the protrusions due to the upper mold prototype, and an integrally molded product with excellent sound absorption is made.

わず後作業が容易となる。(b) In the case of combination of foam material and soft material (compressed urethane, etc.) When foam material and hard material (plywood, etc.) are molded at the same time, take out the product in an unmolded state (light burn) and Although it tried to escape to the back side due to impact resilience, it was hindered by the hardness and mostly appeared as a bulge on the foam material side of the surface, but when a soft material such as compressed urethane was used, the dome shape on the back side The bumps are absorbed by the compressed urethane, the foam material is subjected to sharp double-sided molding, and the soft material (compressed urethane) in contact with the hot plate becomes flat because it is below the molding temperature, leaving only slight imprints. Post work becomes easy without impairing sound absorption.

The adhesive may be applied by either a spray or a roll coater, but a roll coater is preferable in consideration of control of the basis weight and uniform application. In general, the coating amount should be 100 gr / m 2 as a guide, and it should be adjusted appropriately for double-sided coating and large for single-sided coating. After coating, both are combined and temporarily bonded.

Originally, as shown in FIG. 3 and FIG. 4, raised portions which should be formed on both sides are raised partially on the surface due to the influence of the plywood after the mold release, and show a complicated shape. FIG. 2 is an end view taken along the line AA in FIG. 1, in which a void 1a is formed around the protrusion on the back side of the convex portion of the foamed polyethylene 1.

The urethane 4 compressed to 2 to 20 times and the foamed polyethylene 3 are temporarily adhered to each other, and the foamed polyethylene 3 is brought into contact with a mold and molded by hot pressing. In this case, the shape of the convex portion of the foamed polyethylene 3 changes slightly depending on the thickness of the foamed polyethylene 3 and the urethane 4, the compression ratio of the compressed urethane 4, and the like.
Generally, as the compression ratio of urethane becomes higher (harder), the convex part of the foamed polyethylene will be slightly different from the shape of the mold. 3 is double-sided molded.
