Abstract

The invention provides a bamboo-fibril-reinforced modified vegetable oil-base unsaturated polyester composite material and a preparation method thereof. Acrylated epoxy soybean oil is used as the blend substance of the unsaturated polyester, and the bamboo fibrils are used as the reinforcer to prepare the composite material. The modified vegetable oil-base unsaturated polyester used by the composite material is free of the carcinogenic reactive solvent styrene, and therefore, has the characteristics of environment friendliness and low cost. The prepared composite material has very high tensile strength, bending strength, bending modulus and impact strength.

Description

technical field [0001] The invention belongs to the technical field of natural plant fiber-reinforced resin composite materials, and in particular relates to a bamboo fiber-reinforced modified vegetable oil-based unsaturated polyester composite material and a preparation method thereof. Background technique [0002] In recent years, research on the use of natural plant fibers to reinforce polymer composites has received extensive attention. The wall-to-cavity ratio and length-to-diameter ratio of bamboo fiber were significantly larger than those of various wood fibers. Bamboo has the characteristics of large yield, wide distribution and fast growth rate. The bamboo fiber prepared by biosolvent-assisted mechanical rolling method retains relatively high components such as hemicellulose and cellulose, which greatly reduces the degree of fiber damage and has high It is a reinforced material with broad application prospects. Unsaturated polyester (UPE) is the most used resin va...
