Abstract
A resin molding material includes (A) a recycled material and (B) a thermoplastic resin. The recycled material is a mixture including thermosetting urethane, short glass fibers, and polyethylene terephthalate. The recycled material and the thermoplastic resin are mixed with each other such that the recycled material accounts for 5% to 60% by weight and the thermoplastic resin accounts for 40% to 95% by weight, and a total amount of (A) and (B) is 100% by weight.
Claims3
A resin molding material comprising:
- (A) a recycled material that is a mixture including thermosetting urethane, short glass fibers, and polyethylene terephthalate;
- and
- (B) a thermoplastic resin;
- wherein the recycled material and the thermoplastic resin are mixed with each other such that the recycled material accounts for 5% to 60% by weight and the thermoplastic resin accounts for 40% to 95% by weight, and a total amount of (A) and (B) is 100% by weight.

A resin molding material comprising:
- (A) a recycled material that is a mixture including thermosetting urethane, short glass fibers, and polyethylene terephthalate;
- (B) a thermoplastic resin;
- and
- (C) an additive;
- wherein the recycled material and the additive are mixed with the thermoplastic resin such that the recycled material accounts for 5% to 60% by weight, the additive accounts for 0% to 30% by weight (excluding 0% by weight), the thermoplastic resin accounts for 10% to 95% by weight, and a total amount of (A), (B), and (C) is 100% by weight.
2 more elements
A method for recycling thermosetting urethane, the method comprising:
- a recycled material production step of pulverizing a composite material into particles, wherein the composite material includes the thermosetting urethane, glass fibers, and polyethylene terephthalate, and the pulverizing produces a recycled material that is a mixture including the thermosetting urethane, the glass fibers having been shortened, and the polyethylene terephthalate;
- and
- a resin molding material production step of mixing the recycled material with a thermoplastic resin to produce a resin molding material.
