Problems solved by technology

[0003] However, the products obtained by the above-mentioned technology have obvious deficiencies in fluidity. When applied to thin-wall injection molding, obvious under-injection phenomena will occur, especially when ionomers with good nucleating properties are used as nucleating agents. , the mobility decrease is quite obvious

Abstract

The invention relates to a high-fluidity black flame-retardant reinforced polyethylene glycol terephthalate composition and a preparation method thereof. The composition comprises PET resin, a toughening agent, a bromine-containing flame retardant, a flame-retardant synergist, a crystallization nucleating agent, a crystallization accelerator, glass fibers, carbon black, a blue pigment and an antioxidant. By adjusting the viscosity of the PET resin and introducing the crystallization nucleating agent and the crystallization accelerator, the flowability of the material is greatly improved, and the crystallization performance is maintained.

Description

technical field [0001] The invention belongs to the field of engineering plastics, and in particular relates to a high-fluidity black flame-retardant reinforced polyethylene terephthalate composition and a preparation method thereof. Background technique [0002] At present, the research on flame retardant reinforced PET mainly focuses on improving the crystallization performance of PET, so as to achieve the purpose of rapid injection molding. However, based on the needs of the electronic and electrical industry, the requirements for the fluidity of flame-retardant enhanced PET are gradually increasing, and high fluidity is required to meet the needs of thin-walled injection molding. Patent CN1990514A is used for PET resin toughening and crystallization core-shell structure ionomer and its preparation method. The ionomer is mainly used as a nucleating agent to promote crystallization, thereby ensuring the injection molding ability of PET and broadening the range of PET. app...
