Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with specific preferred embodiments.

[0014] An environmentally friendly anti-loss wood flame retardant, its components are proportioned by mass percentage: 35% ammonium polyphosphate, 15% zinc borate, 30% silica sol, 10% antimony oxide, 6% sodium molybdate, ten Sodium dialkylbenzene sulfonate 3%, pentaerythritol 1%. Wherein, the mass content of silica in the silica sol is 20%-40%.

[0015] The preparation method is as follows: weighing each component according to the mass percentage, mixing them evenly, drying, pulverizing and sieving to obtain an environment-friendly anti-loss wood flame retardant of the present invention.

[0016] The steps of carrying out a fire-retardant treatment process on wood by using an environmentally friendly anti-loss wood flame retardant of the present invention are as follows:

[0017] (1) Dry the wood to be treated so that its moisture cont...

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...
