Abstract

The invention discloses a PET / PETG ultra-transparent injection molding demolding master batch and a preparation method thereof. The PET / PETG ultra-transparent injection molding demolding master batch comprises 60-80 KG of an SK2008PETG raw material, 5-8 KG of polyester demolding wax, 8-10 KG of self-prepared demolding wax, 2 KG of a chain extender, 500 G of an antioxidant, 1 KG of a homogeneous nucleating agent, 300 G of high-temperature-resistant toner and 5 KG of dimethyl silicone oil. The preparation method comprises the following steps: grinding the SK2008PETG raw material into powder, then stirring with the chain extender, the antioxidant, the nucleating agent and the toner, and putting into a main machine of a granulator; stirring all wax and simethicone, then putting the mixture into a preheating tank, setting the temperature to be 115 DEG C, and pumping the mixture into a screw of a granulator by using a liquid plunger pump after the wax is completely molten; the materials and the wax are fully mixed and uniformly extruded and granulated in a screw rod through a special thread original part; and cooling, pelletizing, drying and bagging. The invention provides the novel PET / PETG ultra-transparent injection molding demolding master batch and the preparation method thereof, so that the produced PET / PETG ultra-transparent injection molding demolding master batch has excellent comprehensive performance, and the production process is simpler.

Description

technical field [0001] The invention relates to the field of PET / PETG ultra-transparent injection moulding release master batch, in particular to a PET / PETG ultra-transparent injection moulding release master batch and a preparation method thereof. Background technique [0002] PET (polyethylene terephthalate) was first successfully developed in 1941 by British J.tt.Whinfield and J.T.Dickon. PET has been used as a fiber raw material for 70 years and its chemical formula is -OCH2-CH2OCOC6H4CO. Due to its good mechanical properties; oil resistance, fat resistance, dilute acid, dilute alkali resistance, resistance to most solvents; high temperature, low temperature resistance; gas, water, oil and odor resistance; high transparency, can block ultraviolet rays, good gloss ; Non-toxic, tasteless, hygienic and safe, etc., are widely used in food packaging, fibers, films, engineering plastics, polyester bottles, etc. The raw material ratio of the existing PET / PETG ultra-transparent...
