Abstract

The invention discloses a PTT flame-retardant heat-resistant modified master batch and a preparation method therefor. The PTT flame-retardant heat-resistant modified master batch comprises the following ingredients, by weight, 15%-50% of PTT resins, 20%-40% of flame retardants, 2%-5% of heat stabilizers, 0.1%-2% of anti-oxidants, 0.5%-5% of dispersants, 5%-40% of calcium carbonate and 3%-15% of POE. The flame retardants are one or some of decabromodiphenylethane, cyanuric acid melamine, polysulfonyldiphenylene phenyl phosphonate, bisphenol-A bis (diphenyl phosphate), polymethylphenyl sioxane and nano-sized magnesium hydroxide. The beneficial effects are that the PTT flame-retardant heat-resistant modified master batch has characteristics of environmental protection, no pollution, high concentration, high dispersion, high flame retardation, high heat resistance and the like, when the PTT flame-retardant heat-resistant modified master batch is added in the production of PTT, effects of excellent flame retardation, enhancing, toughening and the like are achieved, the modification effects are good, the heat resistance is high, the cost is low, usage is convenient, and the PTT flame-retardant heat-resistant modified master batch is helpful for industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PTT flame-retardant and heat-resistant modified masterbatch and a preparation method thereof. Background technique [0002] Polytrimethylene terephthalate (PTT for short) is a promising new type of polyester polymer material produced by polycondensation of terephthalic acid and 1,3-propanediol. PTT is a semi-crystalline high polymer with high melting temperature and glass transition temperature. It has good wear resistance, heat resistance and chemical resistance, and is widely used in synthetic fibers, films and engineering plastics. . However, unmodified PTT has the defects of low notched impact strength, high notch sensitivity, poor flame retardancy (limiting oxygen index is about 21), and poor heat resistance, which will greatly limit its application in various fields. Contents of the invention [0003] The object of the present invention is to provide a PTT f...
