Abstract

The invention belongs to the technical field of resin composite materials, and particularly relates to a natural bamboo fiber reinforced composite material based on natural polyphenol cross-linked palm oil-based resin and a preparation method of the natural bamboo fiber reinforced composite material. The environment-friendly palm oil-based resin is prepared by blending a natural polyphenol cross-linking agent and palm oil fatty acid acrylamide ethyl ester, and natural bamboo fibers, the palm oil-based resin and an initiator are subjected to hot press molding to obtain the natural bamboo fiberreinforced palm oil-based resin composite material. The natural bamboo fiber reinforced palm oil-based resin composite material prepared by the invention is environment-friendly and has good tensile strength, tensile modulus, bending strength and bending modulus.

Description

technical field [0001] The invention belongs to the technical field of resin composite materials, and in particular relates to a bamboo fiber reinforced composite material based on natural polyphenol crosslinked palm oil-based resin 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. Thermosetting resins have excellent mechanical properties, thermal stability, durability and chemical corrosion resistance due to their high crosslinking density. They have been widely used in construction, anti-corrosion, automobiles, electronic appliances and other fields. The environmental problems and air pollution problems caused by the volatilization of formaldehyde, styrene, etc.) have attracted great attention. In addition, the continuous depletion and rising prices of petroleum resources have forced people to s...
