Glue special for veneer pasting of boards and woods

Abstract

The invention relates to a special glue for a wood veneer, which is prepared by the following steps: mixing 53 parts of nano diatomite or nano silica sand and 5-7 parts of sticky rice wet glue, heating and stirring while mixing until the temperature reaches 60-80 DEG C, preserving heat for 30-40 minutes, and air-cooling to room temperature to obtain a raw material A; and heating 1-2 parts of the raw material A, 5-6 parts of crystal white latex, 1-2 parts of flour and a proper amount of water, and stirring for 20-30 minutes until a small amount of glue is added to generate wire control and slowly flows downwards to find a drawn wire, thereby obtaining the product. The method has the advantages that after the artificial board is glued and scraped, glue, nano diatomite or nano silica sand gathered at the concave small pits of the board can be retained at the concave small pits, the glue at the concave small pits can be automatically leveled, shrinkage of the glue can be reduced in the drying process of the glue, meanwhile, the nano diatomite or nano silica sand is tightly adhered to the board through the glue, and the use effect is good; meanwhile, after the glue is absorbed by the micropores of the nano diatomite, the effect is better.

Description

technical field [0001] The invention relates to the technical field of glue, in particular to a special glue for sticking veneers of boards and wood. Background technique [0002] Wooden furniture is prepared by pasting veneer on the surface of wood-based panels. Wood-based panels include woodworking boards, particle boards, fiberboards, solid wood boards, and solid wood particle boards. Due to processing factors, there are small concave pits on the surface. When pasting the surface of wood-based panels, glue such as white latex is traditionally used. After this kind of glue is coated on the surface of wood-based panels, the concave pits will have positions, and shrinkage will occur. That is, after the glue dries, the glue will shrink. Voids are formed at the concave pits. This kind of voids is easy to cause hollowing, and the second is that due to the shrinkage of the sheet glue, for the flat facing material, the decorative materials at the concave pits will be pulled down ...

Voids are formed at the concave pits. This kind of voids is easy to cause hollowing, and the second is that due to the shrinkage of the sheet glue, for the flat facing material, the decorative materials at the concave pits will be pulled down to form a lower surface.
