Problems solved by technology

[0004] At present, the production process of cork PVC flooring adopts hot-melt adhesive method, and the cork is attached to the back of the PVC floor. On the one hand, the production process is cumbersome. The traditional process uses hot-melt adhesive for lamination, which requires a discharge machine, a roller coating machine, and a pressure roller. As well as a series of processes such as shrinking devices, and a production line needs to be equipped with 5-6 operators, the labor cost and equipment cost are high. On the other hand, the use of hot melt adhesive, there are volatile chemical substances in the hot melt, which reduces the PVC The degree of environmental protection of the floor, and after laminating with hot melt adhesive, the peeling strength of cork and floor is generally low

Abstract

The invention discloses a preparation method of a damping cork PVC (polyvinyl chloride) floor. Coated polymer cork is used as a raw material, an improvement is made by combining a process, so that a cork bonding process is omitted, a hot-pressing bonding process of a hot melt adhesive is omitted, and the cork PVC damping floor is prepared. The floor prepared by the method not only has the advantages of the traditional PVC floor, but also can effectively improve the sound insulation effect, the flatness is good, the peeling strength and warping meet the relevant national or industrial standards, the cork bonding procedure is simplified, the production efficiency is improved, the production cost is reduced, a hot melt adhesive attaching process is omitted, generation of harmful substances isavoided, and safety and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of floor preparation, in particular to a preparation method of a silent cork PVC floor. Background technique [0002] PVC floor, also known as "light floor material", also known as plastic floor, is a new type of light floor decoration material. It is a popular product in Europe, America, Asia, Japan and South Korea, and has been gradually introduced into the Chinese market. It is widely used in various places such as families, hospitals, schools, office buildings, factories, public places, supermarkets, and businesses. PVC floor refers to the floor made of polyvinyl chloride material. Specifically, polyvinyl chloride and its copolymer resin are used as the main raw material, and fillers, plasticizers, stabilizers, colorants and other auxiliary materials are added to the sheet continuous substrate. Coating process or produced by calendering, extrusion or extrusion process. [0003] PVC flooring has the advantages of...
