Description

[Technical field]

[0001] The invention relates to the technical field of floors, in particular to a novel elastic sound-absorbing PVC floor. [Background technology]

[0002] PVC flooring is a new type of lightweight floor decoration material that is very popular in the world today. It is also called "lightweight flooring". It is a product that is popular in Europe, America, Japan and South Korea in Asia. It has been popular abroad. It entered the Chinese market in the early 1980s. It has been generally recognized in large and medium-sized cities in China and is widely used, such as homes, hospitals, schools, office buildings, factories, public places, supermarkets, businesses, and other places. "PVC flooring" refers to flooring made of polyvinyl chloride materials. Specifically, it is made of polyvinyl chloride and its copolymer resin as the main raw materials, with fillers, plasticizers, stabilizers, colorants and other auxiliary materials added. It is produced on a sheet-like continuous substrate through a coating process or by calendering, extrusion or extrusion process.

[0003] However, most existing PVC floors are hard floors with poor comfort and almost no sound insulation performance. Even if the PVC floor is made of foamed material, its sound insulation effect is only slightly improved. In addition, the PVC floor made of foamed material also has the disadvantage of easy dimensional deformation at the foaming part, which affects the appearance and daily use of the floor. Therefore, it is necessary to propose a new type of elastic sound-absorbing PVC floor. [Summary of the invention]
