technical field

The invention relates to the technical field of plastic flooring, in particular to an anti-scald structure formed by coating a surface layer of a plastic floor with a material having a temperature and heat resistance function and a manufacturing process of the anti-scald structure.

Background technique

Traditional plastic floors are mostly PVC (polyvinyl chloride, Poly Vinyl Chloride), PE (polyethylene, Polyethylene), PP (polypropylene, Polypropylene), EVA (ethylene-vinyl acetate copolymer, Ethylene-vinyl Acetate Copo), PU (Polyurethane, referred to as polyurethane, Polyurethane), TPU (thermoplastic polyurethane elastomer rubber, Thermoplastic Polyurethanes) are made of base materials, generally are base layer, pattern layer, pattern protection layer, and the pattern protection layer is transparent plastic , its main function is to protect the pattern layer from being scratched and wear-resistant, thereby improving the service life of the floor, keeping the pattern layer of the floor intact and clear without being damaged, and achieving the decorative effect that the floor should have; however, In daily life, if an unextinguished cigarette butt (the highest temperature of the cigarette butt can reach 800°C in an instant) accidentally drops on the pattern protective layer on the plastic floor, the pattern protective layer touches the cigarette butt, and it is easy to be burned by the cigarette butt. Form imprints and destroy the decorative effect of the plastic floor. If there are many damaged floors, the user must replace multiple floors for the sake of decoration, and the older style of plastic floor may be difficult to match. cause a lot of inconvenience.

Contents of the invention

The object of the present invention is to overcome the deficiencies in the prior art and provide an anti-scald structure of plastic flooring and its manufacturing process. The anti-scald structure formed by the process can make the surface of the plastic floor resist temperature in an instant, and When the unextinguished cigarette end is in contact with the floor surface, the local temperature is quickly dissipated to prevent the plastic floor from being scalded, which greatly enhances the service life of the plastic floor. In addition, the anti-scald structure also has an antibacterial effect.

To achieve the above object, the present invention adopts the following technical solutions:

The anti-scald structure of the plastic floor, which includes a substrate, the upper surface of the substrate is coated with UV resin as a primer layer, and the UV resin with aluminum oxide is coated on the primer layer to form a transition layer, and the transition layer is coated with UV resin coated with titanium dioxide powder and nano silver powder forms a protective surface.

Further, the UV resins of the primer layer, the transition layer and the protective surface layer are solvent-based UV resins.

Further, the solvent-based UV resin is an acrylic modified UV resin.

Further, the thickness of the primer layer is 0.02mm-0.05mm.

Still further, the weight ratio of aluminum oxide and UV resin in the transition layer is 10:100, and the thickness of the transition layer is 0.02mm-0.07mm.

Still further, the UV resin in the protective surface layer: titanium dioxide powder: nano-silver powder = 100:10: 3-5, and the thickness of the protective surface layer is 0.05mm-0.2mm.

Furthermore, the base material is a semi-finished plastic floor.

The process of making the anti-scald structure of the above-mentioned plastic floor, the process steps are as follows:

1) Take the base material to be processed, and after electrostatic dust removal is performed on the surface of the base material, a primer layer is formed on the upper surface of the base material by roller coating;

2) forming a transition layer on the primer layer formed by roller coating;

3) forming a protective surface layer on the formed transition layer by means of curtain coating;

4) UV light curing is carried out on the base material after the protective surface layer is formed to prepare the anti-scald structure of the plastic floor.

Further, the primer layer, the transition layer and the protective surface layer are all formed at an ambient temperature of 25-30°C.

Furthermore, the primer layer, the transition layer and the protective surface layer are all formed at a rate of 3-5 seconds per sheet by means of conveyor belt interlocking.

The beneficial effects of the present invention are: by coating UV resin and UV resin copolymer on the surface of the plastic floor, using the high temperature resistance of alumina and titanium dioxide, a high temperature resistant anti-scald structure is formed, so that the traditional plastic floor can be used in the future. When an extinguished cigarette butt accidentally falls to its surface, the plastic floor resists temperature in an instant, and the thermal conductivity between the molecules of alumina in the transition layer is faster than that of ordinary substances, so the plastic floor is heated locally when it contacts the unextinguished cigarette butt At the same time, due to the effect of alumina, the heat source can be quickly dissipated to the surroundings to achieve the cooling effect, thus avoiding the plastic floor from being scalded and greatly enhancing the service life of the plastic floor; nano-silver added to the UV resin to protect the surface With its permanent sterilization properties, the surface layer of the plastic floor has antibacterial properties, which is beneficial to the health of users.
