Description

Thermoplastic synthetic resin plate manufacturing method and thermoplastic synthetic resin plate material {A method of heating plasticity plastic-plate and heating plasticity plastic-plate}

The present invention relates to a method for manufacturing a thermoplastic synthetic resin plate material and a thermoplastic synthetic resin plate material prepared by the method, and more specifically, by embedding natural color particles on the upper surface of the thermoplastic synthetic resin plate material, sound absorption and hygroscopicity and natural color on the upper surface of the synthetic resin plate material. The present invention relates to a method for producing a thermoplastic synthetic resin plate material and a thermoplastic synthetic resin plate material of a novel type, in which particles can be expressed as it is to improve various textures, aesthetics, and feel on the upper surface of the synthetic resin plate material.

Among the high molecular materials, there is a material that is significantly increased plasticity when heated. These properties are called thermoplastics. Polymers such as polyethylene, PVC, polystyrene, and polymethacrylic acid esters are called thermoplastics (plastics) because they have a large thermoplasticity and can be easily formed when heat and pressure are applied.

Most plastics have plasticity that changes with temperature and deformation rate, and are generally soft at low and high speeds and ductile at high and low speeds.

In addition, some polymer materials have strong interactions between molecules and thus do not show plasticity at room temperature. Such polymer materials may also recede when mixed with a suitable low material, so that they may show distinct plasticity at room temperature.

The main molding method of such thermoplastic synthetic resin, in particular polyethylene or vinyl chloride resin, is extrusion molding, and is a molding method in which a raw material is supplied to an extruder and pushed out of a mold to be converted into a continuous body having a uniform cross section. Rigid vinyl pipes for water, vinyl-coated wires, plates, etc. are typical of extrusion molded products.

At present, many of the consumption of plastics, such as plastic tubes, pipes, troughs, films, plates, stretched tapes, monofilaments, mold releases, wire coatings, and plastic nets, are extruded.

Among these synthetic resin products, the plate form has been changed variously over the years, but development has been focused mainly on improving aesthetics and feel, so that further development has been limited in terms of functionality.

Recently, products with various functions and hardness have been distributed on the market by incorporating mineral powder into the synthetic resin board, but the mixed minerals are not visible on the upper surface of the synthetic resin board and cannot be detected. As a result of the mixing, the unique material possessed by the synthetic resin is damaged, and the elasticity such as the bursting strength and the bending strength is remarkably decreased, which leads to a decrease in durability.

The apparatus for extruding such thermoplastic synthetic resin is composed of basic elements such as an extruder, a mold, a receiving device, and the granular or powdery plastic material supplied to the hopper of the extruder is heated in a heating cylinder made of metal, softened and melted and screwed. It is fed forward while being kneaded and compressed by the rotation of.

The flow of material of homogeneous melt is rectified through a metal disk with many small holes, continuously extruded from the opening of the mold made into the desired shape, and passed through the cooling water tank to be taken as a product.

The extruder of such an extruder is the most widely used single screw type, but there are also two or three screw types, and there are various methods such as compression molding, extrusion molding, injection molding, calendering, and the like. There is this.

Transfer molding is designed for molding thermosetting resins, which have been conventionally performed only by compression molding, and heats and smoothes only one dose injected into the mold, and flows into the mold from small holes such as injection molding.

Looking at the prior art of the method of extrusion molding the thermoplastic synthetic resin plate material with an extrusion molding apparatus, as shown in Figure 1, the extrusion molding apparatus 20 is a plastic material is put into the extruder 21, the plastic injected into the extruder A primary molding roller 22 for extruded material from the die and primary molding with a predetermined width and thickness; a secondary molding roller 23 for secondary molding of a synthetic resin plate material formed by the primary molding roller; , A primary cooling roller 24 for cooling the synthetic resin sheet having a predetermined width and thickness by the secondary molding roller, a secondary cooling roller 25 for cooling the primary cooled synthetic resin sheet in a second manner, and the secondary. A tertiary cooling roller 26 for cooling the cooled synthetic resin sheet in a third order, and a cutter for cutting the synthetic resin sheet having a predetermined width and thickness, which is cooled by the cooling rollers to be at room temperature, to a predetermined length ( 27).

The forming roller is composed of primary and secondary forming rollers (22, 23), which can be selectively added or subtracted according to the conditions, the cooling roller is also the primary, secondary and tertiary cooling roller (24) , 25, 26) but it can be selectively added or subtracted according to the conditions of the place to be installed.

Therefore, the extrusion molding method of the thermoplastic synthetic resin sheet material according to the prior art is, by inserting the plastic material into the extruder of the extrusion molding apparatus, extrusion molding into a synthetic resin plate material by a molding roller while extruding, and extruded synthetic resin plate material to the cooling roller It is produced by cutting to a predetermined length by a cutter while cooling to room temperature by using, the synthetic resin plate material produced by this type of extrusion molding device itself is a single plate to express various textures and aesthetics on the upper surface of the synthetic resin plate material It couldn't be universal.

For example, the flooring made of synthetic resin has a good hardness, abrasion resistance, sound absorption and hygroscopicity, so it is widely used for interior decoration, but it cannot be used because it can cause various textures, aesthetics, and touch on the surface, and the synthetic resin board material is used for interior decoration. In order to use a separate decorative pattern plate is attached to the upper surface of the synthetic resin plate material.

The present invention was developed to solve the above problems, the thermoplastic synthetic resin sheet manufacturing method of the present invention and the thermoplastic synthetic resin plate material, the plastic material is extruded through an extruder having a constant width and thickness of the primary and secondary molding rollers After molding with a thermoplastic synthetic resin plate material, the natural color particles are sprayed on the upper surface of the synthetic resin plate material formed by the molding roller with a spreader, and then the natural color particles are sequentially passed through the cooling rollers by the pressing force of the cooling roller. By being embedded in the upper surface of the synthetic resin sheet to be fixed,

A large number of natural color particles having excellent heat resistance and hardness are embedded on the upper surface of the synthetic resin sheet, and are not only expressed on the upper surface of the synthetic resin sheet, but also dispersed by scattering scattered on the upper surface of the synthetic resin sheet and embedded by a myriad of natural colored particles. Natural color particles are embedded in only the upper surface of the synthetic resin plate while retaining the unique material of the plate without damage, and combining the advantages of synthetic resin with the advantages of natural color particles so that the function and decoration that synthetic resin plate has not had until now It was to have an aesthetic sense.

In addition, by embedding natural color particles having excellent heat resistance and hardness on the upper surface of the synthetic resin plate material, the wear resistance and impact resistance are greatly improved without damaging the unique material of the synthetic resin, and the hygroscopicity and sound absorption are also improved. In addition, natural color particles are expressed on the upper surface of the synthetic resin plate material, and the appearance and feel, such as a gorgeous and elegant texture and aesthetic expression, can be widely used in various fields.
