Abstract

The invention discloses a plant fiber reinforced modified soy-based resin composite material and a preparation method thereof. Cross-linking agents and epoxidized soybean oil acrylate are blended to prepare soy-based resin, the soy-based resin is modified by modifiers to obtain modified soy-based resin, and plant fibers, the modified soy-based resin and initiators are hot-pressed to obtain the plant fiber reinforced modified soy-based resin composite material. The plant fiber reinforced modified soy-based resin composite material has excellent tensile strength, tensile modulus, 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 plant fiber-reinforced modified soybean oil-based resin composite material and a preparation method thereof. Background technique [0002] In natural plant fiber reinforced polymer composites, the most commonly used thermosetting resins are epoxy resins, phenolic resins and unsaturated polyester resins. Generally, these thermosetting resins have good mechanical properties, chemical resistance and process performance, but the environmental and air pollution problems caused by the volatilization of toxic substances (such as formaldehyde, styrene, etc.) during use have caused great focus on. In addition, the continuous depletion of petroleum resources and rising prices have forced people to seek and develop new renewable bio-based resins. Acrylate epoxidized soybean oil (AESO) is obtained by reacting soybean oil with a...
