Eco-friendly anti-loss timber fire retardant and its preparation method and treatment process

Abstract

The invention discloses an eco-friendly anti-loss timber fire retardant and its preparation method and treatment process. The eco-friendly anti-loss timber fire retardant comprises, by mass, 30-40% of ammonium polyphosphate, 5-15% of zinc borate, 15-30% of silica sol, 5-10% of antimony oxide, 2-6% of sodium molybdate, 0.5-3% of sodium dodecyl benzene sulfonate and 0.1-1% of pentaerythritol. The preparation method utilizes ammonium polyphosphate as a main agent, zinc borate, silica sol and antimony oxide as adjuvants, sodium molybdate as a smoke inhibitor, sodium dodecyl benzene sulfonate as a surfactant and pentaerythritol as a charring agent so that the eco-friendly anti-loss timber fire retardant has excellent flame retardance, smoke inhibition and loss resistance performances, is free of halogen, is environment-friendly, has a low cost, simple preparation processes and industrial production feasibility and is suitable for wood materials such as solid boards, fiberboards, shaving boards and glued boards.

Description

technical field [0001] The invention relates to the technical field of wood flame retardants, in particular to an environment-friendly anti-loss wood flame retardant and its preparation method and treatment process. Background technique [0002] Wood is widely used in the fields of construction, transportation, furniture, and interior decoration. However, wood is easy to burn. Once a fire breaks out, it is difficult to control the fire, often causing huge personal and property losses. In order to reduce the fire hazard of wood, it must be treated with flame retardant. However, among the existing wood flame retardants, the use of organic flame retardants is not recommended because they emit a large amount of toxic gases during combustion and are expensive. It has not been widely used due to problems such as the darkening of the material color. The most widely used inorganic flame retardant has the advantages of wide sources, low price, non-toxic and environmental protection...
