Abstract
The invention discloses modified waterproof flame-retardant type biomass board of the compound woodcare paint enhancing of a kind of nano silicon/polyurethane and preparation method thereof, characterized in that, with rice straw, sulfate wood pulp, Carboxyl Modified Polydimethylsiloxane, gelatin, nano imvite, polyoxyethylene nonylphenol ether 10, atoleine, rosin, polyacrylic acid, melamine phosphate, boric acid, hydrotalcite, pine tar, nano silicon, polyurethane carpentry paint etc. as raw material.The present invention carries out enhancing modification to addition Carboxyl Modified Polydimethylsiloxane in rice straw；It is nano montmorillonite modified to process the mechanical property and dimensional stability for significantly improving sheet material；Microcapsules waterproofing agent is prepared using Simple coacervation；Melamine phosphate polypropylene salt borate fire retardant is prepared for, with hydrotalcite synergy, flame retardant effect is more preferably；Obtain a kind of modified waterproof flame-retardant type biomass board of the compound woodcare paint enhancing of nano silicon/polyurethane.
Description
Technical field
The present invention relates to a kind of preparation method of biomass board, and in particular to a kind of nano silicon/polyurethane is multiple
Close modified waterproof flame-retardant type biomass board of woodcare paint enhancing and preparation method thereof.
Background technology
China is Rice Production big country, and rice straw aboundresources can make biomass board, alleviate timber and supply with it
The pressure answered, instead of part woodwork and plastic products, while reducing pollution of the plastics to environment, also makes rice straw resource
More effective utilization is obtained.
Zhang Jin is in its Master dissertation《Using rice straw make can be degradable biomass board》In, with water
Rice straw is raw material, a kind of preparation method of environmentally friendly material-biomass board that can be degradable is elaborated, using pure
Physical method, by the technique such as chopping, immersion, grinding, hot-forming after, be made the biological scutum with some strength
Material.Without the addition of any chemical reagent during panel, saved cost, and it is discarded after degradable can be inhaled by soil
