Manufacturing technology for preparing high-strength bamboo-plastic composite material through MAPE pretreatment

Abstract

The invention relates to a manufacturing technology of bamboo-plastic composite materials, in particular to a preparation method of an MAPE compatilizer for pretreating degree of reinforced agglutination. The manufacturing technology comprises the steps of raw material pretreatment, material mixing, pelleting, crushing, paving and hot-pressing. Through the control for the bamboo-plastic proportioning, the using amount of a coupling agent, the hot pressing temperature and the hot pressing time, the effect of the manufacturing technology with the optimum performance of the bamboo-plastic composite material with the thickness of 9mm is realized. In order to reinforce the performance of the bamboo-plastic board, the compatilizer is used for dispersing among organic fibers, inorganic filler, inorganic fibers and matrix resin, so that the effect of improving the compatibility is reached. Moreover, after the surface of bamboo fiber is pretreated, the interface bonding capacity between matrixes can also be promoted. The mechanical properties of a finished board product are measured through GB/T1449-2005 'Fiber Reinforced Plastic Bending Property Test Method', GB/T1451-2005 'Fiber Reinforced Plastic Simple-beam Impact Toughness Test Method' and GB/T17657-1999 'Artificial Board and Decorative Artificial Board Physical and Chemical Property Test Method', and all reach higher levels.

Description

Technical field: [0001] The invention relates to the technical field of bamboo-plastic composite material manufacturing, in particular to a preparation method for pretreatment of a MAPE compatibilizer to enhance the degree of adhesion. Background technique: [0002] my country is a big country with bamboo resources, with an annual output of 150 million tons, accounting for about one-third of the world's total bamboo output. However, the utilization rate of bamboo resources in my country is still very low. It is only used to produce flooring, simple furniture and some handmade crafts, and has not been used in engineering. The function of bamboo fiber has not been fully developed. [0003] Bamboo is a natural viscoelastic composite material. Bamboo fiber has a large length, a large aspect ratio, and good interweaving properties, so it has strong tensile strength and elongation (Michaud, 2005; Nenkova S, 2006). When bamboo fiber is added as a reinforcing material to the composite mat...
