Technical Field
The invention relates to a preparation method of a bamboo-plastic composite material.
Background
Bamboo resources in China are quite rich, and the areas of bamboo forests, bamboo varieties and economic utilization levels are in the top of the world. Bamboo plants have been increasingly paid attention to by people due to the characteristics of fast growth, short cultivation period and convenient cultivation and management. At present, bamboo in China is mainly used for manufacturing traditional handicraft articles such as baskets, chairs, floors and the like, has low added value and utilization rate, and has great development and application potential. The bamboo-plastic composite material is a material with a novel structure, reduces the usage amount of plastics and environmental pollution, and has great development and utilization prospects. At present, the development of bamboo-plastic composite materials still faces a plurality of technical difficulties, wherein the most important problem is the compatibility problem between bamboo materials and plastics. The bamboo surface is strongly polar and has strong hydrophilicity, while the plastic is non-polar and has strong hydrophobicity, so that the compatibility between the bamboo material and the plastic is poor, and the interface bonding force is small. And the prior bamboo-plastic material has insufficient toughness, water resistance, fire resistance and aging resistance. Therefore, the invention provides the high-strength water-resistant corrosion-resistant fire-resistant aging-resistant bamboo-plastic material.
