Abstract

The invention discloses a plant fiber-reinforced environment-friendly unsaturated polyester composite material and a preparation method thereof. Triethylene glycol divinyl ether is used as a reactive solvent for solid unsaturated polyester, and plant fiber is used as a reinforcement Composite materials are prepared. The plant fiber, reactive solvent, solid styrene-free unsaturated polyester and initiator are formed by thermocompression to obtain the plant fiber reinforced environment-friendly unsaturated polyester composite material. The environmentally friendly unsaturated polyester used in the composite material prepared by the present invention does not contain the carcinogenic reactive solvent—styrene, and has the characteristics of environmental friendliness and low cost. The prepared composite material has high tensile strength, Flexural strength, flexural 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 plant fiber reinforced environment-friendly 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. Hemp fiber has the advantages of large yield, wide distribution, high strength and modulus, and is a kind of reinforcing material with broad application prospects. Unsaturated polyester (UPE) is the most used resin variety in glass fiber reinforced resin composite materials. UPE resin has good mechanical properties and manufacturability, but a large amount of volatile styrene is used as diluent and crosslinking agent in the preparation process, and the resulting air pollution has attracted great attention. In 2011, the U.S. Department of Health ...
