Plywood veneer overlaying and painting process

Abstract

The invention relates to a plywood veneer overlaying and printing process. According to the plywood veneer overlaying and painting process, a base material and a veneer are included. The process comprises the following steps that the base material qualified in appearance is screened; the water content of the base material is detected, the next step is directly carried out on the base material with the water content of 8-10%, and dewatering treatment is conducted on the base material with the water content higher than 10%; the base material with the water content of 8-10% is put for a certain time and recovers balanced, and the base material is polished and ground, so that the thickness of the base material is basically consistent; the face, to be attached to the veneer, of the base material is coated with wood grain masking agents; the face, to be attached to the veneer, of the base material is coated with gum; the base material and the veneer are attached; a semi-finished plywood composed of the base material and the veneer is subjected to hot-pressing; and paint is sprayed on the plywood, and then baking, hot air blowing and baking are sequentially carried out. The process does not need use valuable wood as the base material, the machined plywood is good in quality and achieves the high-end wood sense, and the paint and the base material are high in binding stability and good in anti-disengagement performance.

Description

technical field [0001] The invention relates to the technical field of plywood processing, in particular to veneer veneer and painting process of plywood. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to decoration. Among them, the traditional poplar plywood can no longer meet the requirements of users, so there are relatively high-end plywood made of eucalyptus, mahogany, beech and other materials. , but the above-mentioned precious wood is over-protected, and the exploitation of this kind of wood is restricted. Some plywoods are prone to peeling off after painting due to workmanship defects. Therefore, there is an urgent need for a plywood that does not require precious wood as a base material, but also can achieve the feeling of high-end wood, and has strong bonding stability between paint and base material, and good anti-stripping performance. Contents of the invention [0003] In view of the above...
