Abstract

The invention aims at providing a modified bamboo fiber composite material and a preparation method thereof, which solve the problems of poor mechanical property, low tensile strength, low bending strength and the like of the prepared composite material caused by low interface combination strength of the vegetable fiber and plastics in the prior art. The bamboo fiber composite material of the invention adopts the bamboo fiber, the unsaturated polyester and the evocating agents for hot press molding to obtain the bamboo fiber composite material. After the modified bamboo fiber composite material of the invention adopts a modifying agent for the modification, the modified bamboo fiber, the unsaturated polyester and the evocating agents carry out hot press molding to obtain the modified bamboo fiber composite material. Both the bamboo fiber composite material and the modified bamboo fiber composite material prepared by the method of the invention have good tensile strength, bending strength and flexural modulus.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic composite materials, and more specifically relates to a modified bamboo fiber composite material and a preparation method thereof. Background technique [0002] The total area of ​​bamboo forests in my country is more than 63 million mu, accounting for one-third of the total area of ​​bamboo forests in the world, and the growth cycle of bamboo is short and the price is low. Bamboo fiber has high strength and modulus, and its longitudinal tensile strength and modulus can reach 198MPa and 21MPa respectively. Bamboo has a natural spiral toughened structure, and the density of bamboo is only 0.9g / cm 3 Left and right, bamboo fiber has high specific strength (220MPa·cm 3 / g) and specific modulus (23MPa·cm 3 / g) excellent characteristics. These all make it an excellent resin reinforced material. Unsaturated polyester is one of the most important resin-based composite material matrices. Currentl...
