Wood fire retardant and wood veneer flame-proof processing technique

Abstract

The invention discloses a wood fire retardant which is characterized in that the wood fire retardant consists of the following components in weight percentage: 8 to 12 percent of borax, 8 to 12 percent of boric acid, 8 to 12 percent of cyanogen, 33 to 38 percent of ammonium phosphate, and 33 to 38 percent of ammonium sulfate. The wood fire retardant of the invention can be simply prepared, can offer flame retardancy to wood and can meet requirements for various national standards; the fire retardant property of the wood board which is processed by the board flame retardant of the invention can meet requirements for various national standards; after the fireproof plywood of the invention is subject to the use of the fire retardant of the invention, goes through the veneer processing and then is glue-pressed into complete boards, the flame retardant property of the fireproof plywood is superior to the plywood which is first glud-pressed and then goes through the complete board fame retardant processing.

Description

technical field [0001] The invention relates to a wood flame retardant and a wood flame retardant treatment process. Background technique [0002] Wood is a combustible material and presents a high fire hazard. With the continuous increase in the amount of wood used in furniture, interior decoration and even building structures, as well as the continuous concentration of urban population, the property and personal hazards that fires can cause are increasing. The necessity of fire prevention for wood and wood products is self-evident. In recent years, the application of advanced analytical instruments and the progress of related science and technology have led to significant progress in the field of wood flame retardant research, and initially formed the theory and technology of wood flame retardant. system. [0003] Plywood is one of the main wood materials widely used in interior decoration and other construction projects. However, at this stage, the flame retardant treat...

AI Technical Summary

Problems solved by technology

[0004] ① After the finished plywood is soaked, vacuumed, pressurized and other processes in the process of flame retardant treatment, it is easy to cause serious degumming

[0005] ② Finished plywood, especially thick boards, is often affected by the thickness of glue and multi-layer boards during flame retardant processing. The flame retardant is not easy to penetrate evenly and deeply, and the absorption of the flame retardant cannot reach the standard, which affects the flame retardant effect.
