Embodiment

[0017] A preparation method of ammonium polyphosphate-boric acid compounded fire-resistant and flame-retardant biomass panels, characterized in that, the steps are as follows:

[0018] a. Cut 60kg of rice stalks into 10-15mm fragments with a pulverizer, soak them in clear water for 3 days, then mechanically grind them for 30 minutes with a grinding machine, and separate them into wire brooms to obtain a rice straw suspension;

[0019] b. Add N,N dimethylformamide to 5kg graphite oxide at a ratio of 1:2, and disperse evenly by ultrasonication for 1h to form a suspension. Add 0.3kg triethylamine and 2kg hexadecyltrimethoxysilane, and stir magnetically for 40min. In an oil bath and a nitrogen atmosphere, stir and reflux for 5 hours, filter and wash to obtain modified graphite oxide;

[0020] c. Add distilled water to 4kg liquid paraffin at a ratio of 1:3, heat to 80-90°C, add 3kg OP-10 emulsifier, stir and emulsify for 1 hour to obtain emulsified liquid paraffin, add 10kg monomer...

Abstract

The invention discloses an ammonium polyphosphate-boric acid compounded fireproof flame retardance biomass board and a preparation method thereof. The ammonium polyphosphate-boric acid compounded fireproof flame retardance biomass board is characterized by comprising the following steps: shearing a rice straw into pieces, soaking in clear water, mechanically grinding, and fibrillating to obtain a rice straw suspension liquid; adding N,N-dimethylformamide, triethylamine and hexadecyltrimethoxysilane into graphite oxide, stirring, backflowing and carrying out a reaction under a nitrogen environment in an oil bath to obtain modified graphite oxide; adding distilled water and an emulgator into a liquid paraffin, stirring and emulsifying, adding a monomer crylic acid, an initiator and the modified graphite oxide, carrying out a reaction to obtain a wear resistant waterproofing agent; adding a modifying agent KH570 and absolute ethyl alcohol into ammonium polyphosphate, heating, stirring, conducting suction filtration, drying to obtain modified ammonium polyphosphate, mixing the modified ammonium polyphosphate and boric acid, and grinding to obtain a compounded fireproof flame retardant; mixing the rice straw suspension liquid, the wear resistant waterproofing agent and the compounded fireproof flame retardant, conducting ultrasonic vibration to disperse, evenly filling a mold, and compressing, drying and forming in a hot press to obtain the biomass board.

Description

technical field [0001] The invention relates to the field of plates, in particular to a fire-resistant and flame-retardant biomass plate compounded with ammonium polyphosphate-boric acid and a preparation method thereof. Background technique [0002] Biomass charcoal is a solid product obtained by pyrolyzing biomass materials such as crop straws and sawdust under the environmental conditions of limiting or isolating oxygen. Due to the high ash content, the biochar prepared from crop stalks and other wastes is limited in the industrial field, but it can be widely used in the agricultural field. [0003] In Zhang Jin's master's degree thesis "Using Rice Straw to Make Completely Degradable Biomass Sheets", using agricultural waste rice straw as raw material, using purely physical methods, through chopping, soaking, grinding, hot pressing and other processes After that, a biomass board with a certain strength is made. However, there are insufficient waterproof and fireproof pe...
