Inorganic wood flame retardant with good loss-resistant property

Abstract

The invention discloses an inorganic wood flame retardant with good loss-resistant property. The inorganic wood flame retardant comprises the following components in percentage by weight: 40%-60% of ammonium polyphosphate, 10%-20% of silicon dioxide solutions, 5%-10% of boric acid, 5%-10% of sodium borate, 2%-10% of basic magnesium carbonate, 0.5%-3% of alkyl sodium sulfonate and 0.1%-1% of pentaerythritol. Compared with the prior art, the inorganic wood flame retardant disclosed by the invention has the beneficial effects of containing no prohibited component, namely halogens, heavy metals and the like, belonging to a green environmental-friendly flame retardant, being low in cost, having the effects of flame retardance, smoke inhibition, corrosion prevention, moth prevention and the like on a wood and being good in loss-resistant property and high in stability.

Description

technical field [0001] The invention relates to the technical field of wood flame retardants, in particular to an inorganic wood flame retardant with good anti-loss performance. Background technique [0002] Commonly used wood flame retardants include aluminum hydroxide, magnesium hydroxide, ammonium sulfate, ammonium bromide, boric acid, ammonium dihydrogen phosphate, ammonium phosphate, guanidine phosphate, ammonium polyphosphate, etc., and one or more of them have Flame retardant effect. Among wood flame retardants, organic flame retardants are not recommended because they emit a large amount of toxic gases when burned and are expensive; resin-based flame retardants, due to their unsatisfactory flame retardant performance and difficulty in impregnation, the color of the treated material will change. Deep and other problems, not widely used, currently the most widely used inorganic flame retardant, has the advantages of wide sources, low price, non-toxic and environmental...

Problems solved by technology

Among wood flame retardants, organic flame retardants are not recommended because they emit a large amount of toxic gases when burned and are expensive; resin-based flame retardants, due to their unsatisfactory flame retardant performance and difficulty in impregnation, the color of the treated material will change. Deep and other problems, not widely used, currently the most widely used inorganic flame retardant, has the advantages of wide sources, low price, non-toxic and environmental protection, but its anti-loss performance needs to be improved
