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 co

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:...
