[0002] Wood flame retardant treatment has a long history. In the late 1940s, attempts were made to use urea and other weakly basic organic nitrogen compounds for phosphoric acid esterification, which reacted in wood to form phosphoric acid condensates, which made wood not only flame retardant but also resistant to loss. , but the po

Abstract

The invention discloses a composite flame retardant wood and a production process thereof. The composite flame retardant wood comprises a first board, a rubber pad, a second board, a third board, a bonding layer, a bump, a limiting slot, limiting blocks and a guide post, wherein the guide post is arranged on the top of the first board; the two ends of the top of the guide post are equipped with the limiting blocks; a guide sleeve is uniformly mounted on the bottom of the second board; and the limiting slot and the bump are matched components. According to the composite flame retardant wood disclosed by the invention, the third board covers the second board, the bump and the limiting slot are matched and fixed, and are bonded through the bonding layer which is made of super glue, so that the damping effect is very good under action of a spring and the rubber pad, and therefore, vibrations can be reduced; diammonium hydrogen phosphate, magnesium sulfate, ammonium borate, ammonium chloride, a de-foaming agent and a dispersing agent, which are in special proportion, are heated and mixed, are stirred and cooled, and are filtered and are screened; and the boards are eroded and are driedin air, so that easy leachability of an inorganic flame retardant is effectively overcome on the premise of keeping the original appearance of the wood.

Description

technical field [0001] The invention relates to the technical field of fire retardant equipment, in particular to a composite fire retardant wood and its production process. Background technique [0002] Wood flame retardant treatment has a long history. In the late 1940s, attempts were made to use urea and other weakly basic organic nitrogen compounds for phosphoric acid esterification, which reacted in wood to form phosphoric acid condensates, which made wood not only flame retardant but also resistant to loss. , but the pollution is relatively serious; due to the development of the times, people pay more and more attention to the protection of environmental issues, and products that bring great harm to the environment are gradually abandoned by people, and the use of halogen flame retardants that pollute the environment is extremely popular. big limit. The development trend of flame retardants is towards the development trend of non-toxic, smoke-suppressing and high-effi...
