Abstract

The invention discloses a toughened polytrimethylene terephthalate alloy and a preparation method thereof. The impact resistance of polytrimethylene terephthalate is improved. The toughened polytrimethylene terephthalate alloy comprises the following raw materials in parts by weight: 70-95 parts of polytrimethylene terephthalate, 5-30 parts of acrylonitrile-butadiene-styrene copolymer, 1-15 parts of 'nucleus-shell' silicon rubber latex particles, 1-10 parts of acrylonitrile-butadiene-styrene copolymer grafted maleic anhydride, 0.1-1 part of main antioxidant and 0.1-1 part of auxiliary antioxidant. The polytrimethylene terephthalate alloy disclosed by the invention has higher notch impact strength and tensile strength, is widely applied to the fields of mechanical industry, automobile industry and electronics, and has great application values.

Description

technical field [0001] The invention belongs to the field of polymer alloy materials, in particular to a toughened modified polytrimethylene terephthalate alloy and a preparation method thereof. Background technique [0002] Polytrimethylene terephthalate, referred to as PTT, is obtained by polycondensation of terephthalic acid and 1,3-propanediol. A promising new type of polyester polymer material newly developed after glycol ester (PBT). Compared with PET and PBT, PTT has many excellent characteristics such as high elasticity, good continuous printing and dyeing characteristics, anti-ultraviolet, anti-internal stress, low static electricity, good biodegradability, and recyclability. In addition, PTT has good processability, low hygroscopicity, high dimensional stability, and small change in physical properties. It has both the high performance of PET and the easy processability of PBT. Therefore, PTT has very broad application prospects in many fields such as carpet indu...
