Environment-friendly ABS/PET (acrylonitrile-butadiene-styrene/polyethylene glycol terephthalate) alloy and preparation method thereof

Abstract

The invention relates to the technical field of PET modification, and in particular relates to an environment-friendly ABS / PET (acrylonitrile-butadiene-styrene / polyethylene glycol terephthalate) alloy and a preparation method thereof. According to the environment-friendly ABS / PET alloy and the preparation method disclosed by the invention, PET is recovered, thus the cost is low and the needs of green and environment-friendly sustainable development can be met; the adopted nanometre calcium carbonate and heavy calcium carbonate can be used as either a reinforcer or a nucleator, thus overcoming the defects of filling ABS and PET by independently using heavy calcium carbonate and nanometre calcium carbonate, and keeping good mechanical properties; acrylate and glycidyl ester bifunctional ethylene elastomers and methyl methacrylate-butadiene-styrene terpolymer are used as a composite toughener, which are complementary and exert a synergistic effect, thus improving the compatibility between ABS and PET, and then improving the mechanical properties of the ABS and PET alloy. In a word, according to the environment-friendly ABS / PET alloy and the preparation method disclosed by the invention, the mechanical properties and high temperature resistance of the ABS and PET alloy are improved through a complete formula system; the environment-friendly ABS / PET alloy and the preparation method are simple in production process and low in cost.

Description

technical field [0001] The invention relates to the technical field of PET modification, in particular to an environmentally friendly ABS / PET alloy and a preparation method thereof. Background technique [0002] ABS resin has the characteristics of chemical resistance, stable size, high surface gloss, low temperature resistance, good coloring performance and good processing performance. It is a thermoplastic engineering plastic with a wide range of uses. The main application fields are automobiles, electronic appliances and building materials. However, the mechanical properties of ABS are poor. In order to make up for these deficiencies, people have carried out a series of modification work on ABS, using alloy technology, and blending ABS resin with other plastics to maintain the original excellent performance of ABS. Improve the deficiencies of ABS resin. [0003] Polyethylene terephthalate (PET) is a thermoplastic semi-crystalline engineering plastic. Due to the high rig...

However, the mechanical properties of ABS are poor. In order to make up for these deficiencies, people have carried out a series of modification work on ABS, using alloy technology, and blending ABS resin with other plastics to maintain the original excellent performance of ABS. Improve the deficiencies of ABS resin

[0003] Polyethylene terephthalate (PET) is a kind of thermoplastic semi-crystalline engineering plastics. Due to the high rigidity of the main chain, the movement of the chain segments is slow, so There are disadvantages such as slow crystallization rate and low crystallization degree, which greatly limit its application in the field of engineering plastics
