Problems solved by technology

[0004] 1. Due to the large length-to-diameter ratio of bamboo fiber, the material fluidity is poor when preparing composite materials, and the molding processing method is limited. Generally, only the molding method can be used for processing, and the widely used extrusion processing cannot be carried out. At the same time Composite materials prepared by molding method have poor apparent properties, which limits their application
[0005] 2. The interface compatibility between bamboo fiber and polyethylene (PE) is poor
Dry single fibers are easy to flocculate into agglomerates, resulting in poor dispersion uniformity of fibers and poor fluidity of the composite system, which affects the performance of composite materials

Embodiment 1

[0042] A flame-retardant and mold-proof bamboo-plastic board. The raw materials of the flame-retardant and mold-proof bamboo-plastic board in parts by weight include: 25 parts by weight of polyethylene, 65 parts of bamboo powder, 15 parts of rice husk, 5 parts of halogen antimony flame retardant, 2 parts of composite preservative, 1 part of talc, 0.5 part of maleic anhydride, 10 parts of silane coupling agent, 0.5 part of soda ash, 3 parts of coloring agent; the composite preservative consists of chlorothalonil and pyrethrin in a weight ratio of 1: 2 composition.

[0043] The bamboo powder is prepared from the leftovers of bamboo heads. Specifically, the leftovers of bamboo heads are transported to a high-temperature and high-pressure carbonization pot, and the carbonization treatment is carried out at a steam pressure of 0.4 MPa and a temperature of 150°C for 50 minutes. The carbonized bamboo is transported to The drying oven is dried at 55°C for 120 hours, and dried to a moistu...

Embodiment 2

[0051] A flame-retardant and mold-proof bamboo-plastic board. The raw materials of the flame-retardant and mold-proof bamboo-plastic board in parts by weight include: 25 parts by weight of polyethylene, 65 parts of bamboo powder, 15 parts of rice husk, 5 parts of halogen antimony flame retardant, 2 parts of composite preservative, 1.5 parts of talc, 0.5 part of maleic anhydride, 10 parts of silane coupling agent, 0.5 part of soda ash, 3 parts of coloring agent; the composite preservative is composed of chlorothalonil and pyrethrum in a weight ratio of 1: 2 composition.

[0052] The preparation method of the bamboo powder is: bamboo felling-cleaning and disinfection (50% H 2 O 2 +50%H 2 O, 80℃ / 8h)-natural drying (natural drying 48 hours  )-  crushing (crusher)-primary crushing (hammer crusher)-fermentation, covering the bamboo shavings and stacking insulation materials for 28 days , Keep the moisture content 12%-secondary crushing (hammer mill, heated air 150℃ to control the moist...

Abstract

The invention provides an inflaming-retarding mildew-proof bamboo-plastic board and a preparation method thereof. The inflaming-retarding mildew-proof bamboo-plastic board comprises, by weight, 25 parts of polyethylene, 65 parts of bamboo powder, 15 parts of unhulled rice, 5 parts of a halogen-antimony flame retardant, 2 parts of a compound preservative, 1-1.5 parts of talcum powder, 0.5 part of maleic anhydride, 10 parts of a silane coupling agent, 0.5 part of sodium carbonate and 3 parts of a coloring agent. The inflaming-retarding mildew-proof bamboo-plastic board is low in cost, has excellent inflaming-retarding mildew-proof performance and is broad in market prospect.

Description

Technical field [0001] The invention specifically relates to a flame-retardant and mold-proof bamboo plastic board and a preparation method thereof. Background technique [0002] In recent years, the Chinese government has strictly prohibited the use of natural forests to produce wooden products, and has strictly restricted the use of natural forests to produce wooden products, which has provided an opportunity for the development of the bamboo industry. The bamboo industry is playing an increasingly important role in promoting the economic development of mountain regions The bamboo industry has gradually expanded its processing scale. Using bamboo branches, bamboo heads, bamboo shavings and other scraps as raw materials, cheap, renewable, and degradable bamboo-plastic composite materials have the characteristics of low cost, excellent performance, and environmental friendliness. The mechanical strength is higher than that of wood-plastic composite materials. It is another new ty...
