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.
