Abstract

The invention relates to a photocatalystc composite floor board, and belongs to the field of a functional environment-friendly healthy floorboard. The formaldehyde emission content of the composite floorboard is less than 0.3mg/L; the antibacterial rate is higher than or equal to 90 percent; the surface wear-resistant coefficient is less than or equal to 0.08g/100r; a substrate layer is an oriented shaving board layer; the oriented shaving board layer comprises an upper surface layer and a lower surface layer which are formed by glue mixing wood shavings in longitudinal arrangement according to the fiber direction and a core layer shaving layer formed by glue mixing wood shavings in transverse arrangement according to the fiber direction; and a decoration layer, a wear-resistant primer layer and a photocatalystc antibacterial paint decoration layer are sequentially arranged on the substrate layer. A production process of the photocatalystc composite floor board comprises the steps of shaving board layer sorting, glue preparation, glue distribution and assembling for the first time, cold pressing for the first time, core trimming, glue distribution and assembling for the second time, cold pressing for the second time, hot pressing for the first time, fixed-thickness sanding, edge cutting, puttying, polishing, sorting, reconditioning, glue distribution and veneering, cold pressing for the third time, hot pressing for the second time, multi-blade sawing, sanding, double-end milling, priming, finish paint preparing and finish paint painting. The composite floorboard has the advantages of good antibacterial function, high strength, good wear-resistant performance and comfortable foot feeling.

Description

technical field [0001] The invention relates to a photocatalyst composite floor, which belongs to the field of functional environment-friendly and healthy floors. Background technique [0002] There are various volatile organic compounds and harmful microorganisms in people's living environment, which directly affect people's physical and mental health. Most pathogenic bacteria in the living environment often come from the ground dirt and pets. The floor is in direct contact with the human body, and it is easier to transmit the microorganisms that breed germs and bacteria to the human body. In the past, people sprayed chemical anti-mold and anti-bacterial agents around the room to solve the air quality problem in the room. However, ordinary anti-mold and anti-bacterial agents are highly toxic, have poor heat resistance and durability, and are sprayed on floors and decorations. The surface of the board is easy to change color and affect the appearance. As people's requireme...
