Anti-scratch foam wall covering

Abstract

The invention relates to the technical field of wall coverings, in particular to an anti-scratch foamed wall covering, comprising an activated carbon non-woven fabric layer, an anion layer compounded on the activated carbon non-woven fabric layer, and an anti-scratch anti-scratch layer compounded on the anion layer. Foaming layer, the anti-scratch foaming layer is formed by anti-scratch foaming slurry, the anti-scratch foaming slurry includes the following raw materials: acrylate modified polyurethane dispersion, curing agent, citrate plasticizer, Nano graphene oxide, titanium dioxide, elastic microsphere foaming agent, heat stabilizer, nano inorganic powder, water. The wall covering of the present invention has the advantages of high hardness, scratch resistance, and the coating is not easy to fall off, and the inventive wall covering also includes an activated carbon non-woven fabric layer, which has strong "physical adsorption" and "chemical adsorption" effects, and can effectively absorb harmful substances. Gas, anti-virus and deodorizing effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of wall coverings, in particular to a scratch-resistant foaming wall covering. Background technique [0002] Foamed wall coverings are made of cloth as the base material, coated with resin mixed with a foaming agent, and then heated and foamed after printing. "Foaming", also known as screen relief foaming, refers to adding a foaming agent to the raw materials, supplemented by high temperature during the production process, so that the foaming agent completes a process similar to "fermentation", so the foamed wall covering will have unevenness Feel, soft to the touch. [0003] Traditional PVC foam wall coverings have the characteristics of poor hardness, easy collapse under force, and not resistant to scratches. Therefore, the development of PVC foam wall coverings has been greatly restricted. The above-mentioned problems in traditional PVC foam wall coverings are mainly caused by the following two reasons:...

Problems solved by technology

[0003] Traditional PVC foam wall coverings have the characteristics of poor hardness, easy collapse under force, and not resistant to scratches. Therefore, the development of PVC foam wall coverings has been greatly restricted.

The above-mentioned problems in traditional PVC foam wall coverings are mainly caused by the following two reasons: 1. The degree of polymerization of PVC paste resin used in traditional PVC foam wall coverings is generally 950-1050, and the degree of polymerization of PVC with this degree of polymerization is generally 950-1050. Paste resin belongs to PVC paste resin with lower degree of polymerization, and PVC paste resin with lower degree of polymerization has lower hardness, lower resilience, higher compression set, weaker tensile strength and wear resistance 2. In the PVC paste used in traditional PVC foam wall coverings, 20%-30% of inorganic fillers are generally added, and the most important inorganic fillers are heavy calcium carbonate, talcum powder and titanium dioxide. And the particle size of the inorganic fillers used is generally 400-1000 mesh, although the addition of inorganic fillers can save a certain amount of cost, and can improve the hardness and rigidity of the whole system by a small amount, but because these inorganic fillers of several microns or even tens of microns and PVC paste resin, DOP, viscosity reducer, foaming agent and other polymers and organic materials have significant differences in chemical structure and physical form, which makes the whole system lack of affinity, and therefore, the strength of the whole PVC foaming system is reduced. And toughness is greatly reduced, affecting the quality of PVC foam wall covering
