Embodiment Construction

[0016] A low expansion rate 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 16.4, preservative 1.5, waste tire rubber powder 7.5, ascorbyl palmitate 0.9, nano polytetrafluoroethylene 1.4, melamine cyanurate 1.7, isooctyl tin dimethyldithioglycolate 0.5.

[0017] The described low expansion rate waste tire rubber powder modified bamboo fiber board is characterized in that:

[0018] (1) Pass 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 20 minutes, and then heat Under the condition of UV aging for 9 hours, and then condensed at 40 ℃ for 4 hours, the rubber powder is processed in this way for one week to obtain modified rubber powder;

[0019] (2) Take 160 parts by weight of 0.2% sodium hydroxide solution, mix and stir with soybean protein isolate, ascor...

Abstract

The invention discloses a low-expansion-rate waste tire rubber powder modified bamboo fiberboard. The low-expansion-rate waste tire rubber powder modified bamboo fiberboard is prepared by the following raw materials in parts by weight: 162-164 parts of bamboo fibers, a proper amount of 0.2% sodium hydroxide solution, 16.2-16.7 of soy isolate proteins, 1.5-1.6 of preservatives, 7-8 of waste tire rubber powder, 0.8-1 of ascorbyl palmitate, 1.3-1.6 of nanometer polytetrafluoroethylene, 1.5-1.8 of cyanuric acid melamine, and 0.4-0.6 of dimethyl dithioglycolic acid diisooctyl tin. The bamboo fiberboard uses the waste tire rubber powder for modifying, so that the board surface shows excellent hydrophobicity; and ascorbyl palmitate, nanometer polytetrafluoroethylene, cyanuric acid melamine and dimethyl dithioglycolic acid diisooctyl tin are used, so that the board is excellent in water and oil resistance, low in water expanding rate, excellent in ageing resistance, excellent in light resistance and suitable for manufacturing indoor and outdoor office furniture and floors.

Description

technical field [0001] The invention relates to the field of bamboo fiber board manufacturing, in particular to a low expansion rate 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 envi...
