Abstract

The present invention relates to a method for manufacturing thermoplastic rubber multi-color or single-color floor tiles or wall tiles. The method is characterized in that thermoplastic rubber is matched with different colors to be orderly formed by injection molding on a disk type multi-color injection molding machine; in the injection process of a first mould in a semi-solidifying state, the first mould is injected into a second mould to form an integrated multi-color floor tile or wall tile with multiple patterns by controlling the rotation speed of the disk.

Description

Thermoplastic elastomer monochrome and polychrome floor wall tile method for making

The present invention establishes and a floor wall tile method for making, is meant the method with flexible thermoplastic rubber manufactured place nogging.

At present, with elastomeric material decorative floor wall rubber floor tile, plastic floor tile are arranged, wherein the floor wall tile with the caoutchouc vulcanization manufacturing has good wear-resisting, non-skid property, but technological process is long in the manufacture process, need high-energy equipment, behind the sulfidization molding, need the polishing epidermis, the burr and the defective goods that downcut can't reclaim use, are unfavorable for environmental protection.With the plastic floor tile that polyvinyl chloride is made, its speed of production is cheap soon, yet serviceability is poor.Especially anti-skid wearable, cold-resistant and tearing toughness is too poor, because it is polyvinyl chloride can discharge chlorine, unfavorable to living environment.

The purpose of this invention is to provide a kind of floor wall tile, it is quality softness, anti-skid wearable not only, and can make the textured brick that multiple color is formed.

The object of the present invention is achieved like this: cooperate thermoplastic with thermoplastic elastomer; plasticizer, hinder right agent, antioxidant and ultra-violet absorber; add colouring agent; in automatic pressurization kneader, mediate; again after the comminutor granulation; according to the needs of making monochrome or multicolor brick; with an injection machine or with continuous multi-color injection molding machine moulding different parts successively; because the thermoplastic elastomer of the another kind of color of injection moulding when a kind of thermoplastic elastomer of color half coagulates is formed the decorative pattern floor wall tile so can form the polychrome that combines together.

Owing to adopted such scheme, it is attractive in appearance to can be made into color, the floor wall tile that pattern is changeable, and be that one-shot forming need not be cut edge and surfacing, speed of production is fast, and energy consumption is low, is suitable for a large amount of productions, and defective goods reclaim usefulness again, compliance with environmental protection requirements.

The present invention is further described below in conjunction with drawings and Examples:

Fig. 1 is a manufacturing process of the present invention.

Fig. 2 is the stereogram of manufactured goods of the present invention.

Fig. 3 is the schematic diagram that the present invention uses three look injection machines.

Fig. 4 is the schematic diagram that the present invention uses two look injection machines.

100 parts of thermoplastic elastomers (styrene---ethene---butylene embedding shape copolymer) in Fig. 1; (styrene---butadiene embedding shape copolymer) adds 20～40 parts of thermoplastic (polystyrene; high impact polystyrene; polymethylstyrene; polypropylene; polyethylene; ethene acetic acid---vinyl ester copolymers); add 0～20 part of plasticizer (aromatic oil; naphthene series oil); fire retardant (antimony oxide; zinc oxide; aluminium hydroxide; magnesium hydroxide; zinc carbonate; Firebrake ZB; phosphate) 30～60 part; 1 part of 1 part of ultra-violet absorber of antioxidant; colouring agent is put into automatic pressurization kneader for 1 part and is mediated; again through the comminutor granulation; put into the different parts that multi-color injection molding machine forms shaped brick successively, form the floor wall tile of spending more the many colors of line.

To make floor tile shown in Figure 2 is example.Among Fig. 3, three

units

21,22,23 of three look injection machines are the injection moulding different parts respectively, the top layer 30 of 4 through holes of 21 injection mo(u)lding tools of injection machine, another color bottom of 22 injection mo(u)ldings of injection machine half 32, the bottom 33 of the another kind of face of 23 injection mo(u)ldings of injection machine, the brick surface forms the decorative pattern that three kinds of colors have four patterns.The injection machine of present embodiment is established 12 groups of mould 1-12, and whenever turning around to go out 12 products, the rotating speed of control garden dish 20 in the production, and injection moulding second look made finished product be fused into one when injection moulding for the first time half was coagulated.

Fig. 4 is another embodiment, is the dichromatism injection moulding, and technology is identical with first embodiment.

Claims

1, the manufacture method of a kind of flexible thermoplastic rubber polychrome or monochromatic floor wall tile, it is characterized in that: per 100 parts of thermoplastic elastomers add 20～40 parts of thermoplastics, add 0～20 part of plasticizer, add 30～60 parts of fire retardants, add a antioxidant, a ultra-violet absorber, add a colouring agent and put into kneader kneading back granulation, through injection mo(u)lding of the same colour is monochromatic finished product or the multi-color injection molded make-up machine of the disc type different parts of injection moulding brick successively, utilize the control disc rotation speed, make first mould be injection-moulded in the mode of half injection moulding when coagulating, second mould, make repeatedly that injection moulding combines together, and make the finished product of spending more the many colors of line.
