Embodiment 1

[0023] 90% ABS, 10% PET regrind by weight percentage, and 0.72% compound antioxidant by their total weight were first put into a high-speed mixer with a rotation speed of about 1000rpm and mixed for 5 minutes, and then Put it into a twin-screw extruder, extrude and granulate under the conditions of a processing temperature of 170-220°C and a screw speed of 900 rpm. The compound antioxidant is composed of 1010 and DLTP at a ratio of 1:3 by weight.

Embodiment 2

[0025] Be 80% ABS by weight percentage, 20% PET return material, and be 0.64% compound antioxidant by their gross weight first put into the high-speed mixer that rotating speed is about 1000rpm and mix 5 minutes, then Put it into a twin-screw extruder, extrude and granulate under the conditions of a processing temperature of 170-220°C and a screw speed of 900 rpm. The compound antioxidant is composed of 1010 and DLTP at a ratio of 1:3 by weight.

Embodiment 3

[0027] Be 70% ABS by weight percentage, 30% PET return material, and put into the high-speed mixer that rotating speed is about 1000rpm and mix 5 minutes first with their total weight of 0.56% compound antioxidant, and then Put it into a twin-screw extruder, extrude and granulate under the conditions of a processing temperature of 170-220°C and a screw speed of 900 rpm. The compound antioxidant is composed of 1010 and DLTP at a ratio of 1:3 by weight.

Abstract

The invention provides an ABS/PET alloy material with high performance and low cost. 30-95 percent of ABS and 5-70 percent of recovery PET multipolymer by weight are premixed with complex antioxidizer which is 0.1-1 percent of the total weight of the material, and the mixture is put into a double-screw extruding machine for pelleting under a normal machining condition to obtain the ABS/PET alloy material. The PET used in the invention is an unformed PET multipolymer prepared from common PET and dihydric alcohol through the modification by copolymerization, and the unformed PET multipolymer is evenly dispersed in an ABS base material to form a dispersing phase area with small size and good compatibility, therefore, the obtained alloy material not only obviously improves the tensile-strength, the rupture tensile stretch and the gap impact strength of the ABS, but also remarkably increases the melt index; in addition, the invention does not use compatilizer and impact modifying agent with high price, but uses the recovery PET multipolymer with low price, thereby greatly reducing the cost, being widely applied to industries of automobiles, electronic and electric appliances, household electric appliances, precise machinery, building materials, and the like, and having obvious economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of PET / ABS blended materials, and in particular relates to an ABS / PET alloy material which not only improves the impact performance, tensile performance and flow performance, but also reduces the cost. Background technique [0002] ABS refers to a terpolymer composed of acrylonitrile, butadiene, and styrene. It not only has good impact performance and surface hardness, but also has good coloring, gloss, oil resistance, chemical corrosion resistance, and cold resistance. Good performance and molding fluidity. Due to its excellent comprehensive performance, ABS has become the most sold and widely used thermoplastic engineering plastic, widely used in the automotive industry, electrical and electronic industry, light industrial appliances, textile and construction industries, as well as consumer and industrial product markets. However, compared with general-purpose plastics, such as polyethylene, polypropylene...
