Abstract

The present invention relates to a method of manufacturing a plastic stacked structure material including an aluminum extruded material protruding from a surface as an inner core, and a foamed plastic stacked structure material manufactured thereby, in which the foamed plastic stacked structure material has a beautiful surface while being evaluated as a product having excellent durability, heat resistance, heat insulation, soundproofing, and dustproofing properties, the foamed plastic stacked structure material is applied instead of a single-aluminum extruded material or a single-plastic extruded material, and the foamed plastic stacked structure material is able to replace a wood product. According to the present invention, stacked plastic is closely coupled to the aluminum extruded material having a concavo-convex surface so that a defect caused by separation or the like does not occur in subsequent application, and spread of a fire is blocked by the aluminum material that is the inner core when the fire occurs so that the plastic stacked structure material is used as a non-combustible material.

Description

A method for manufacturing a plastic laminated structural material including a surface-extruded aluminum extruded shape member inwardly, and a foamed plastic laminated structural material by the same

The present invention relates to a method for manufacturing a foamed plastic laminated structural material including an aluminum extruded shape member protruding from the surface, and to a foamed plastic laminated structural material manufactured by the method, particularly applied to window sashes, furniture structures, floors, ceilings, or sinks possible,

It relates to a plastic laminated structural material having an aluminum pipe extruded shape member with a protruding surface inside.

Aluminum extruded profile members, despite the variety and robustness of their shapes, lack the unique cold feeling and thermal insulation, soundproofing and dustproofing properties of metal. There is a downside to not being able to. On the other hand, the plastic extruded shape member lacks rigidity and can be bent or cut, and in particular, it is not only dangerous in case of fire, but also has a non-recyclable aspect, which is pointed out as a disadvantage.

The present invention is proposed to take advantage of aluminum structural materials and overcome the limitations of plastics, use an aluminum extruded profile with a protruding surface as the inner core, and use a single layer of plastic that does not generate toxic gas in case of fire or its It is to provide a new structural material that is thickly laminated with the above layers, and the structural material according to the present invention can be applied as a structural material that can replace PVC window and door chassis or aluminum window and door chassis.

In order to overcome the disadvantages of conventional aluminum extruded shape members, there is an alternative material that wraps PVC decorative sheets using an adhesive, but the problems of insulation, soundproofing and dustproofing are still not solved. On the other hand, an aluminum composite panel (refer to FIG. 6) or an aluminum sheet panel (FIG. 7) has been proposed as an attempt at aluminum and plastic composite materials, but it cannot be properly applied to the window and door field using five shape members, and the manufacturing process is complicated and In addition to the manual process, the problems such as insulation and sound insulation were still not resolved.

The present invention proposes an optimal non-combustible structural material that combines the advantages of aluminum extruded profiles, particularly pipe aluminum extrusions applied to window and door chassis, and the advantages of plastic structural materials. In particular, to provide a non-combustible structural material to which an aluminum extruded shape member having a surface unevenness is applied to strengthen the surface bonding between the aluminum extruded shape member and the laminated plastic and to prevent separation.
