Abstract

The invention discloses a PET(PETG) (poly(ethylene terephthalate)(polyethylene terephthalate glycol)) tackifying and toughening agent. The PET(PETG) tackifying and toughening agent comprises the following components in parts by weight: 10-40 part of PET particles, 1-10 parts of SEBS (hydrogenated styrene-butylenes-styrene), 10-40 parts of liquid toughening agent, 10-30 parts of liquid brightening agent, 0.2-0.8 part of antioxidant, 0.1-1.0 part of heat stabilizer, 0.1-1.0 part of chain extender and 2-4 parts of talcum powder. The PET(PETG) tackifying and toughening agent provided by the invention has the advantages that a preparation technology is simple and can be easily realized, production efficiency is high, the PET(PETG) tackifying and toughening agent can be applied to a raw material and also can be applied to a return material, the problem that a chain extender can be applied to the PET return material only is solved, and effect is much better compared with the chain extender; the PET(PETG) tackifying and toughening agent is directly crosslinked with molecules, so that viscosity and physical and chemical properties are improved.

Description

technical field [0001] The invention relates to a production method of a polymer material, in particular to a PET (PETG) thickening and toughening agent. Background technique [0002] Chain extender is a necessary reagent in the production of polyurethane. Polyurethane is a prepolymer formed by the reaction of aliphatic and aromatic monomers containing diisocyanate groups with polyester or polyether containing dibasic or polyols. Application When adding a chain extender to shape the resin. Commonly used chain extensions are small molecule alcohols or ether alcohols containing binary or polyhydric hydroxyl groups; in the production of polyurethane rubber and fibers, some compounds containing active hydrogen are commonly used to react with isocyanate-terminated prepolymers, resulting in extended molecular chain diffusion , and presents a hard chain segment, this compound is called a chain extender; in production, some compounds containing active hydrogen are commonly used...
