Problems solved by technology

[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

Abstract

The invention discloses a composite flame-retardant wood and its production process, which comprises a first plate, a rubber pad, a second plate, a third plate, an adhesive layer, a bump, a limit groove, a limit block and a guide post. The top of the first plate is provided with a guide post, and both ends of the top of the guide post are provided with limit blocks, and the guide sleeve is evenly installed on the bottom of the second plate, and the limit groove and the protrusion are matching components. In the invention, the third plate is covered on the second plate, fixed by the cooperation of the protrusion and the limit groove, and bonded by the adhesive layer. The adhesive layer is super glue, which has a good lightening effect under the action of the spring and the rubber pad. Shock effect, can reduce vibration; through a specific ratio of diamine hydrogen phosphate, magnesium sulfate, ammonium borate, ammonium chloride, defoamer and dispersant, and mix by heating; stirring and cooling; filtering and screening; erosion of plates; drying , on the premise of retaining the original appearance of wood, it effectively overcomes the easy loss of inorganic flame retardants.

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...
