Method for manufacturing recombined bamboo decorative veneers

Abstract

The invention discloses a method for manufacturing recombined bamboo decorative veneers. Urea resin, a modified starch emulsion and a polyvinyl acetate emulsion are mixed, a corresponding curing agent and a corresponding reinforcing agent are added, and an adhesive for soaking bamboo bundles is obtained; the bamboo bundles soaked with the adhesive can be directly die-pressed without being dried, and is solidified in a normal temperature state so as to manufacture recombined bamboo. The water content of the recombined bamboo can reach about 30% generally, and can be directly sliced so as to obtain the recombined bamboo decorative veneers meeting quality requirements. According to the method, the modified starch emulsion and the polyvinyl acetate emulsion are added to the adhesive so that humidifying and softening can be conducted, and the recombined bamboo decorative veneers meeting the requirements are manufactured. The modified starch emulsion is added to achieve the purpose that cost of the adhesive can be lowered, the recombined bamboo decorative veneers have higher competitiveness, and good economic benefits are obtained.

Description

technical field [0001] The invention relates to the technical field of making decorative veneers from bamboo, in particular to a method for making decorative veneers by reorganizing bamboo and then slicing. Background technique [0002] my country is a country with large bamboo resources in the world. In recent years, my country's bamboo resources have been well developed and utilized. In order to solve the practical problems of low utilization rate of bamboo resources and difficult development of high value-added products, experts in the bamboo industry have made continuous technological innovations. Many new products have been developed, and recombinant bamboo is also a new product developed under this background. Such as recombined bamboo flooring, decorative materials, etc., are made by sawing recombined bamboo squares, and industrial production has been realized at present. [0003] Recombined bamboo is a new bamboo material that reorganizes and strengthens bamboo bundl...

Problems solved by technology

If it can be realized by slicing, the yield rate can be greatly improved. However, due to the low moisture content, high density and hard bamboo of bamboo, it must be treated with high temperature, humidification and softening before slicing.

However, since the phenolic resin adhesive is a water-resistant adhesive, it is difficult to perform high-temperature humidification and softening treatment, which makes it difficult to plan normally.
