Wear resistant type plastic floor and its production technology

Abstract

The present invention relates to an abrasion-resistant plastic floor board and its production process. Said process includes the following steps: using waste and old plastic powder as main raw material, adding active calcium carbonate and plastic filling agent as auxiliary raw material, mixing them and extruding them to obtain plastic foamed granules, die-pressing and forming, cooling, setting, drawing and cutting so as to obtain the invented plastic base plate, then sticking plastic protection film on its surface, so that the invented plastic floor board finished product can be made up.

Description

technical field

[0001] The invention relates to a wear-resistant plastic floor and its production process, in particular it is used for decoration of homes and offices, and belongs to the technical field of decoration materials. Background technique

[0002] The floor that is used for family, office room decoration usually adopts solid wood floor or compound floor on the market at present. Solid wood flooring consumes a lot of wood and is expensive. Although it has the advantages of wear resistance, it has poor water resistance after laying and use, and is easy to crack and warp. Composite flooring is made by mixing and extruding wood chips and adhesives. Although it has the advantages of lightness and cheap price, it has poor water resistance and wear resistance, low mechanical properties, instability, and it will also warp after being soaked in water. The decorative effect is poor and the service life is short, so it is not easy to be accepted by people. Contents of the...
