Flame-retardant decorative veneer

Abstract

The invention discloses a flame-retardant decorative veneer, which is formed by compounding flame-retardant veneer plywood taken as a base board and barks of natural rare trees. A flame-retardant veneer plywood is produced through a method as follows: placing wood veneers in a flame retardant solution to perform dipping treatment; applying mixed adhesive to the upper surfaces and the lower surfaces of the veneers after the veneers are dried; assembling the veneers into a plate blank after the adhesive is applied, and then performing the processes of cold pressing, hot pressing, cutting edge, sanding, surface treating and the like to obtain the flame-retardant veneer plywood product. A flame retardant is a mixture of low ammonium polyphosphate, ammonium phosphate, ammonium pyrophosphate, urea phosphate, boric acid, and pentaerythritol, and the mixed adhesive is a mixture of wood adhesive, inorganic filler, and a curing agent. The flame-retardant decorative veneer prepared by the method has the advantages of excellent flame-retardant and fireproof performance, environmental protection performance, mechanical properties, and decoration function.

Description

(1) Technical field [0001] The invention relates to a decorative veneer, in particular to a flame-retardant decorative veneer. (2) Technical background [0002] With the improvement of our country's economic development and living standards, and the improvement of people's affluence, many occasions where wood-based panel products are used, such as construction, furniture, vehicles, etc., have put forward higher requirements. The surface layer of the decorative veneer is covered with natural precious tree species veneer, which replicates the unique texture, color and decoration effect of natural precious tree species, and at the same time greatly reduces the amount of natural precious wood used to save resources and protect the environment. Therefore, it is widely used in interior decoration, furniture manufacturing and other fields, but wood itself is a flammable material, and the extensive use of wooden decorative veneers poses a huge potential threat to people's life safet...

Problems solved by technology

Therefore, it is widely used in interior decoration, furniture manufacturing and other fields, but wood itself is a flammable material, and the extensive use of wooden decorative veneers poses a huge potential threat to people's life safety. Once a fire breaks out, it will also cause environmental pollution and huge economic loss

Especially fires in public places often cause heavy casualties and property losses
