A kind of silicon magnesium boron wood nano flame retardant

Abstract

The invention discloses a silicon magnesium boron lumber nano combustion inhibitor, the combustion inhibitor comprises the following raw materials by weight percentage: 30%-36% of sodium silicate hydrate, 24%-30% of elemental silicon, 4%-6% of tin chloride, 20%-30% of zinc borate, 15%-17.5% of basic magnesium carbonate and 2%-2.5% of magnesium chloride, the sodium silicate hydrate, elemental silicon and basic magnesium carbonate have particle sizes of 15nm, 30nm and 50nm and are mixed according to the mass ratio of 1:1:1, the tin chloride, zinc borate and magnesium chloride are micron-grade, sodium silicate hydrate, elemental silicon and basic magnesium carbonate are uniformly mixed, a mixture of the combustion inhibitor and water are performed a disperse treatment for 30-40 minutes by polyethylene glycol, sodium dodecanesulphonate, sodium acid pyrophosphate or sodium hexametaphosphate under the condition of supersonic wave and microwave, the dispersed suspension fluid of the combustion inhibitor is mixed with the aqueous solution of tin chloride, zinc borate and magnesium chloride and stirred for 20m minutes to obtain the silicon magnesium boron lumber nanometer combustion inhibitor. The present invention has the advantages of good fireproof effect, simple technology, easy industrialization, cleanness and no pollution.

Description

technical field [0001] The invention relates to a nano flame retardant, in particular to a silicon magnesium boron nano flame retardant. Background technique [0002] At present, few flame retardants have good flame retardant effect and smoke suppression effect at the same time. Most of the main components of flame retardants are organic substances. The preparation process of flame retardants is complicated, the cost is high, and the pollution is large.
