Description

Technical Field

[0001] The present invention relates to the technical field of floors, in particular to an environment-friendly glue-free self-adhesive floor.

Background Art

[0002] PVC floor is a very popular new type of light-weight floor decoration material in the world today, also known as "light-weight floor material". It is a product widely popular in Europe, America, Japan and South Korea in Asia. It has become popular abroad and entered the Chinese market in the early 1980s. So far, it has been widely recognized in large and medium-sized cities in China and is very widely used, such as in various places like families, hospitals, schools, office buildings, factories, public places, supermarkets, commerce, etc. "PVC floor" refers to the floor produced by using polyvinyl chloride materials. Specifically, it uses polyvinyl chloride and its copolymer resin as the main raw materials, and adds auxiliary materials such as fillers, plasticizers, stabilizers, and colorants. It is produced on a continuous sheet substrate through a coating process or a calendering, extrusion or extrusion process.

[0003] When installing the existing PVC floors, external glue needs to be used to stick the bottom of the floor to ensure that the floor does not slide on the ground. However, in this way, the volatile substances in the glue will accumulate under the floor for a long time and slowly overflow from the gaps between the floors, polluting the indoor environment for a long time and being unfavorable to people's living. Now, there are also some PVC floors with self-adhesive properties on the market, but most of these PVC floors use the entire back of the floor as the sticky surface, with a large self-adhesive area, serious waste of adhesive, and the bonding efficiency cannot be compared with that of glue. In addition, the installation methods of these two types of floors both have the problem of inconvenient floor replacement. Therefore, it is necessary to propose an environment-friendly glue-free self-adhesive floor.

Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art and propose an environment-friendly glue-free self-adhesive floor. The present invention is reasonably designed and has a simple structure. By setting the upper splicing layer and the lower splicing layer, the self-adhesive floor is divided into the upper half and the lower half of the self-adhesive floor. The lower half ensures the self-adhesiveness of the floor, and the upper half ensures the wear resistance, anti-slip and waterproof properties of the PVC floor. The upper splicing layer and the lower splicing layer also give the floor a certain seismic resistance and sound absorption. Multiple separable self-adhesive strips are provided at the bottom of the lower half of the self-adhesive floor. When the adhesiveness of some self-adhesive strips decreases, the self-adhesive strips can be replaced at any time to achieve the re-self-adhesion of the floor.

[0005] To achieve the above object, the present invention provides an environmentally friendly self-adhesive floor without glue, including the upper half and the lower half of the self-adhesive floor.
