Method for improving the bonding performance of PVC / LVL composite decorative profiles by atmospheric plasma process

Abstract

The present invention discloses a method for improving the gluing performance of PVC / LVL composite decorative profiles by using an atmospheric plasma process. The gluing between polymer materials such as wood and plastic is difficult due to the incompatibility of the interfaces between the two. Currently, physical or chemical methods are often used to pre-treat the plastic surface or the wood surface to solve the incompatibility problem between the wood and polymer materials, but the cost is mostly high, or the treatment process is not suitable for industrial production. The present invention uses an atmospheric plasma treatment method to perform plasma treatment on the surface of a plastic plate. The atmospheric plasma treatment can be performed in the atmosphere, and can effectively improve the gluing performance between a wood board and a plastic board. Compared with vacuum plasma treatment, atmospheric plasma treatment has no restrictions on the size of the treated specimen, and can be continuously treated. The composite board suitable for industrial production can meet the strength and aesthetic requirements of decorative profiles.
