Coating-type flexible glue for veneer, and preparation method and implementation process of coating-type flexible glue

Abstract

The invention discloses coating-type flexible glue for veneer, and a preparation method and implementation process of the coating-type flexible glue. The glue comprises the following components in percentage by weight: 10%-40% of monomers, 50%-80% of UV elastic resin, 0.4%-0.5% of an auxiliary and 5-10% of a photoinitiator, wherein the monomer is a mixture of isoborneol acrylate, cyclotrimethylolpropane methylal acrylate, dipropoxylated neopentyl glycol diacrylate and ethoxylated trimethylolpropane triacrylate. According to the coating type flexible glue provided by the invention, one-time simple brush coating is carried out on the surface of veneer, and curing is carried out under an ultraviolet (UV) lamp, so that an excellent softening effect is obtained. The glue has good elasticity after forming a film, the veneer is more flexible, and the cracking does not occur when the veneer is folded by 180 degrees in a cross-grain direction or in a vertical-grain direction. The coating-type flexible glue is economic and environmentally friendly, the process is simple, the application of the veneer in the veneering field is expanded, and the use value of the veneer is improved.

Description

technical field [0001] The invention belongs to the technical field of veneer treatment, in particular to a preparation method and implementation process of a coating-type flexible glue for thin veneer. Background technique [0002] Whether it is woodwork manufacturing or interior wall decoration, it is usually necessary to spray paint on the surface of the object, so that it increases the appearance and protects the surface of the object. But painting or painting can waste a lot of manpower, material and financial resources, and is a time-consuming and labor-intensive work. In order to overcome this cumbersome process, more and more families are choosing veneer veneer decoration. The veneer and its veneer decoration industry started in the 1950s. After half a century of development, veneer veneer decoration has shown leapfrog development in my country's furniture industry and interior decoration industry; to choose veneer as a veneer, it is usually necessary to plan the tr...

Problems solved by technology

The veneer and its veneer decoration industry started in the 1950s. After half a century of development, the veneer veneer decoration has shown leapfrog development in my country's furniture industry and interior decoration industry; to choose veneer as a veneer, it is usually necessary to plan the tree Cut into 0.10-0.80mm thick, but affected by the brittleness and breakage of the thin veneer itself, especially when it is attached to some uneven surfaces or parts that need to be bent, it often breaks due to bending problem, workers had to spend a lot of time repairing the cracks

In addition, the sliced ​​veneer usually has a difference between horizontal grains and vertical grains. Currently, the technical means used include softening with softeners, oil glue coating, glue protection and paint coating, etc., although it can prevent the thin veneer from breaking phenomenon, but the vertical grain will still break when it is folded in half at 180 degrees, so it is necessary to carry out more effective treatment on the surface of the veneer veneer, so that the veneer can be applied to various complex surface conditions in both horizontal and vertical grain directions
