Abstract

The invention discloses a nano-bamboo-carbon filling modified PTT toughening master batch. The toughening master batch comprises the following ingredients, by weight, 15%-50% of PTT resins, 15%-40% of nano bamboo carbon, 3%-8% of compatilizers, 2%-6% of heat stabilizers, 0.5%-3% of dispersants, 15%-25% of calcium carbonate, 10%-20% of POE, 0.1%-1% of methacrylic acid and 0.01%-0.1% of initiators. The beneficial effects are that the toughening master batch has advantages of good core-shell toughening effects, high concentration, no pollution, low cost and convenient usage, and has functions of strong adsorption, sterilization, deodorization, purification, anti-ultraviolet ray and the like. When 10%-25% of the master batch is added during PTT production, modified effects of good toughening, sterilization, aging-resistance and filling are achieved, mechanical properties and heat resistance of materials are raised obviously, the cost is lowered, and therefore the nano-bamboo-carbon filling modified PTT toughening master batch has good practical values and application prospects.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PTT toughening masterbatch filled and modified with nanometer bamboo carbon. Background technique [0002] Polytrimethylene terephthalate (PTT) is a kind of poly(ethylene terephthalate) (PET) and polybutylene terephthalate obtained by polycondensation of terephthalic acid and 1,3-propanediol. Alcohol ester (PBT) is a new type of polyester polymer material, and PTT is more excellent than PET and PBT in terms of mechanical properties, weather resistance, heat aging resistance and hydrolysis resistance. Due to its excellent comprehensive properties, PTT is widely used in the fields of fibers, films, engineering plastics, etc. However, when PTT is used alone, it has the defects of low notched impact strength and high notch sensitivity, which will greatly limit the application of PTT in various fields. Nano-bamboo charcoal has a strong adsorption capacity, adjusts humidi...
