Abstract

The invention discloses an isocyanate-cross-linked soybean oil-based resin / natural fiber composite material and a preparation method thereof. The method comprises the following steps: adopting a di-functional group isocyanate monomer as a cross-linking agent of epoxy soybean oil acrylate, and preparing soybean oil-based thermosetting resin of which the degree of cross linking, the viscosity and the heat resistance are greatly improved; carrying out hot press molding for natural fiber, the isocyanate-cross-linked soybean oil-based resin and an initiator, and thus obtaining the natural fiber-reinforced soybean oil-based resin composite material. The prepared natural fiber-reinforced soybean oil-based thermosetting resin composite material has good 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, in particular to an isocyanate-crosslinked soybean oil-based resin / natural fiber composite material. 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 acrylic acid after epoxidation. At prese...
