Problems solved by technology

However, since the current PVC floor technology is still in the initial stage of development, technical personnel in the field lack scientific control over the formula components of PVC floor, and the production process of PVC floor is also in the stage of exploration. Therefore, there are still some reasons for the existing PVC floor. The technical problem of unstable physical properties caused by the environment and temperature changes affects the service life and effect of PVC flooring
In addition, the existing PVC floor has poor skid resistance and elasticity, and it needs to be laid with glue to make it better bonded to the ground, which increases the difficulty of construction and increases the construction cost, and the glue often contains toxic ingredients, which makes PVC flooring cannot be completely non-toxic and environmentally friendly. All of the above are technical problems that are being studied and solved by technicians in this field.

Description

technical field [0001] The invention relates to the technical field of PVC flooring, in particular to a glue-free PVC flooring and a manufacturing method thereof. Background technique [0002] 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. Flooring produced by coating processes or by calendering, extrusion or extrusion processes. Because PVC flooring has the advantages of novel appearance, wear resistance, stain resistance and anti-skid, and the plastic raw materials are widely sourced and reusable, it is in line with the concept of environmental protection and energy saving advocated by today's society. PVC flooring with environmental protection and superior performance It is already a very popular new light-weight floor decoration material in the world, especially popular ...
