Embodiment 1

[0022] PET waste fiber / bamboo fiber reinforced soybean oil-based resin composite material:

[0023] The preparation process of soybean oil-based resin is as follows: soybean oil derivatives (42 g) and crosslinking agent (18 g) are placed in a round bottom flask, and stirred with a magnetic stirrer at room temperature for 5 minutes to obtain a soybean oil-based resin mixture; The soybean oil derivative is AESO; the crosslinking agent is GTMA; the initiator is TBPB.

[0024] Composite material preparation method: Weigh 60g of soybean oil-based resin mixture and 1.2g of TBPB, mix and stir for 3 minutes with a glass rod. Take the dried fiber felt out of the oven, wrap it in a plastic airtight bag, and when it is cooled to room temperature, 2 pieces of PET waste fiber / bamboo fiber fiber felt (60g) are laminated and arranged in the orthogonal direction to form a fiber slab. Uniformly mixed soybean oil-based resin and additives are evenly coated on both surfaces of the fiber mat, th...

Abstract

The invention belongs to the technical field of fiber-reinforced resin composites and particularly relates to a PET (polyethylene terephthalate) waste fiber / bamboo fiber reinforced styrene-free soybean-oil-based resin composite and a preparation method thereof. The reactive solvent glycerol trimethacrylate is blended with epoxidized soybean oil acrylate to prepare styrene-free soybean-oil-based resin; PET waste fiber / bamboo fiber, soybean-oil-based resin and an initiator are subjected to hot pressing to obtain the PET waste fiber / bamboo fiber reinforced styrene-free soybean-oil-based resin composite. The PET waste fiber / bamboo fiber reinforced styrene-free soybean-oil-based resin composite prepared herein has good environmental friendliness, has good tensile strength, tensile modulus, flexural strength, flexural modulus and impact strength, and is equal to styrene-crosslinked soybean-oil-based resin composites in mechanical performance.

Description

technical field [0001] The invention belongs to the technical field of fiber-reinforced resin composite materials, and in particular relates to a polyethylene terephthalate (PET) waste fiber / bamboo fiber reinforced styrene-free 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 and rising prices of petroleum resources have forced people to seek and develop new renewable bio-based resins. Acrylate epoxidized soybean oil (AESO) is obt...
