Definitions
- the present invention relates to the field of wood fire prevention technology, and in particular to a method for preparing a fireproof coating for wood.
- CN104861809A discloses a wood fireproof coating whose composition is in mass ratio: polyacrylate emulsion 25% ⁇ 40%, melamine polyphosphate 15% ⁇ 20%, ammonium bicarbonate 8% ⁇ 12%, magnesium chloride 8% ⁇ 15%, zinc borate 4% ⁇ 8%, nano aluminum hydroxide 5% ⁇ 15%, pentaerythritol 2% ⁇ 10%, sodium molybdate 1% ⁇ 4%, triiso-hard Isopropyl acyl titanate 1% ⁇ 2%, calcium stearate 0.5% ⁇ 1%.
- the actual application found that the comprehensive performance of flame retardant and anticorrosion of such wood fire retardant coatings is still poor, which affects its promotion and application.
- the present invention is directed to a deficiencies in the prior art, and provides a method for preparing a fireproof coating for wood.
- the fireproof coating prepared by the method has excellent fire resistance, corrosion resistance, water resistance and weather resistance. Such as comprehensive performance, suitable for promotion and application.
- a method for preparing a fireproof coating for wood comprising the following parts by weight of raw materials: 13-19 parts of modified melamine resin; 16-22 parts of phenolic resin; ketone-aldehyde resin 13-15 5 parts of polysiloxane, 32-3 parts; 25-30 parts of acrylate-styrene-vinyl acetate terpolymer; silicone modified styrene-acrylic emulsion 20-23 5 parts of pentaerythritol; 10-12 parts of styrene; 6-9 parts of lignin fiber; 7-9 parts of hydroxyethyl cellulose; 3-5 parts of iron oxide red; 7-8 parts of melamine; 10-12 parts; polyvinyl alcohol 5-8 parts; silicon carbide powder 4-6 parts; mica 2-4 parts; calcium stearate 3-4 parts; nano barium sulfate 6-8 parts; nano magnesium hydroxide 3- 5 parts; 120-150 parts of deionized water;
- the preparation method comprises the following steps:
