Example Embodiment

[0013] A heavy bamboo board for outdoor non-structural use, made of the following raw materials in parts by weight (kg): 110 dried bamboo shreds, 430 liquefied resin adhesive (solid content: 21%) of Camellia oleifera husk, 0.5 penetrant, trifluoroacrylic acid Ethyl ester 5.5, nano polytetrafluoroethylene 5.5, dodecafluoroheptyl methacrylate 6.5, titanate coupling agent 0.6, cumene peroxide 0.4, nano zinc oxide 2.5, amino resin 1.3, maleic anhydride 2.3, Nano titanium dioxide 2.5.

[0014] The outdoor non-structural heavy bamboo board is characterized in that:

[0015] (1) Cook and carbonize the dried bamboo shreds, and then dry them until the moisture content is 8%;

[0016] (2) The camellia oleifera husk liquefied resin adhesive (21% solid content), nano-polytetrafluoroethylene, trifluoroethyl acrylate, dodecafluoroheptyl methacrylate, titanate coupling agent, nano-zinc oxide, Mix maleic anhydride and nano-titanium dioxide, heat to 65°C, then add cumene peroxide, stir and r...

Abstract

The invention discloses an outdoor non-structural heavy bamboo board. The outdoor non-structural heavy bamboo board comprises the raw materials: in parts by weight, 100 parts to 120 parts of dry bamboo filament sheets, 400 parts to 450 parts of an oil-tea-fruit-shell liquidation resin adhesive (the solid content ranges from 20% to 22%), 0.4 part to 0.5 part of a penetrant, 5 parts to 6 parts of trifluoroethyl acrylate, 5 parts to 6 parts of nano-polytetrafluoroethylene, 6 parts to 7 parts of dodecafluoroheptyl methacrylate, 0.5 part to 0.8 part of titanate coupling agent, 0.4 part to 0.5 part of dicumyl peroxide, 2 parts to 3 parts of nano-zinc oxide, 1 part to 1.5 parts of amino resin, 2 parts to 2.5 parts of maleic anhydride and 2 parts to 3 parts of nanometer titania. According to the outdoor non-structural heavy bamboo board, glue liquor is modified through the trifluoroethyl acrylate, the nano-polytetrafluoroethylene and the dodecafluoroheptyl methacrylate, the water resistance, the oil resistance, the corrosion resistance and the antifouling performance of the heavy bamboo board can be improved, and the size deformation of the board can be reduced; and the stability, the high temperature resistance, the acid-base resistance and the light aging resistance of the board are improved through the nano-zinc oxide, the maleic anhydride, the titanate coupling agent and the nanometer titania.

Description

technical field [0001] The invention relates to the field of heavy bamboo manufacturing, in particular to a heavy bamboo board for outdoor non-structural use and a preparation method thereof. Background technique [0002] As the second largest forest resource in my country, bamboo has increasingly significant industrial and commercial value because of its strong reproduction and regeneration ability, short growth cycle, and excellent material quality. Bamboo can be processed through mechanical physical processing and chemical processing to produce various bamboo products. Substituting bamboo for wood can reduce wood consumption and effectively alleviate the contradiction between wood supply and demand. [0003] The heavy bamboo board is drawn through bamboo strips, loosened, then carbonized and anti-corrosion treated, and formed by high-pressure pressing. The prepared board has high strength, high density, anti-ultraviolet, water and mildew resistance, environmental protect...
