Embodiment Construction
[0016] A heat-resistant waste tire rubber powder modified bamboo fiber board, made of the following raw materials in parts by weight (kg): bamboo fiber 163, 0.2% sodium hydroxide solution, soybean protein isolate 16.5, preservative 1.5, waste tire rubber powder 7.5, carboxylated graphene 2.5, polyurethane emulsion 2.5, cashew nut shell liquid 0.6, micron bamboo charcoal powder 1.5.
[0017] The heat-resistant waste tire rubber powder modified bamboo fiber board is characterized in that:
[0018] (1) Pass the waste tire rubber powder through a 200-mesh sieve, mix it with 3 times the weight of 0.2% sodium hydroxide solution, stir at 50°C for 17 minutes, and then put UV aging under the same conditions for 8 hours, and then condensed at 38°C for 3.7 hours, and the rubber powder was treated in this way for a week, and then mixed with polyurethane emulsion and micron bamboo charcoal powder to obtain modified rubber powder;
[0019] (2) Take 160 parts by weight of 0.2% sodium hydrox...

Abstract
The invention discloses a heat-resistant bamboo fiber board modified by waste tyre rubber powder. The heat-resistant bamboo fiber board modified by waste tyre rubber powder is prepared from the following raw materials in parts by weight: 162-164 parts of bamboo fibers, a proper amount of sodium hydroxide solution with concentration being 0.2%, 16.2-16.7 parts of isolated soybean protein, 1.5-1.6 parts of preservative, 7-8 parts of waste tyre rubber powder, 2-3 parts of carboxylated graphene, 2-3 parts of polyurethane emulsion, 0.5-0.7 part of cashew nut shell oil and 1-2 parts of micro bamboo charcoal powder. The waste tyre rubber powder is used for modifying the bamboo fiber board, so that the surface of the board has good hydrophobic property; and by use of carboxylated graphene, polyurethane emulsion and micro bamboo charcoal powder, the board has good heat resistance and high toughness, is widely applied to furniture, floor and the like, and has a wide market space.
Description
technical field [0001] The invention relates to the field of bamboo fiber board manufacturing, in particular to a heat-resistant waste tire rubber powder modified bamboo fiber board and a preparation method thereof. Background technique [0002] Fiberboard has uniform structure, smooth surface and good processability, so it is widely used in furniture manufacturing and construction. At present, the main raw materials for preparing fiberboard are wood fiber and urea-formaldehyde resin adhesive. With the excessive felling of forest resources, how to ensure sufficient supply of raw materials has become an important social and economic issue. In addition, urea-formaldehyde resin is derived from non-renewable petrochemical resources, and it is easy to release free formaldehyde in hot and humid environment, which seriously pollutes the environment and endangers human health. With the continuous rise of crude oil prices and people's increasing concern about their own and environm...
