Embodiment 1-2

[0034] Prepare materials according to the components in Table 1. in,

[0035] Component A: ABS high rubber powder. The butadiene content of ABS is 54%, the styrene content is 34%, and the acrylonitrile content is 12%, produced by Kumho Petrochemical in South Korea;

[0036] Component B: Styrene Acrylonitrile Copolymer (SAN). The molecular weight of SAN is 125000, wherein styrene: butadiene=72:28, South Korea Kumho Petrochemical production;

[0037] Component C: Recycled PET, derived from recycled PET beverage bottles, is broken into after thorough cleaning;

[0038] Component D-1: Styrene-acrylonitrile copolymer-glycidyl methacrylate terpolymer (SAN-GMA), GMA content is 5%;

[0039] Component E: processing aids, including lubricant ethylene bis stearamide, phosphite antioxidant IRGAFOS?? 168, hindered phenol IRGANOX1076 and silicone mold release agent Dow Corning MB-50, the weight ratio of the four is 2:1:2:1.

[0040] The ABS high rubber powder, styrene acrylonitrile co...

Embodiment 3

[0054] Prepare materials according to the following components: ABS 15kg, SAN 25kg, PET 50kg, compatibilizer D-1 1kg, antioxidant (hindered phenol + phosphite) 0.1kg, lubricant 0.1kg.

[0055] First, the ABS high rubber powder, styrene acrylonitrile copolymer (SAN), and compatibilizer are fully mixed in a high mixer and then exported, and then put into a screw machine to extrude and granulate. The speed of the screw machine is 300-400rpm. The temperature is 200-220°C to make compatibilized masterbatch. Then fully mix the compatibilizing masterbatch and the rest of the above components in a high-mixer and then export them, and then put them into a screw machine for extrusion and granulation. The speed of the screw machine is 300-500rpm and the temperature is 225-260°C. ABS / recycled PET resin composition. The performance of the ABS / regenerated PET resin composition was tested in the same way as in Example 1-2, and the results are shown in Table 2.

Embodiment 4

[0057] Prepare materials according to the following components: ABS 60kg, SAN 5kg, PET 5kg, compatibilizer D-1 10kg, antioxidant (hindered phenol + phosphite) 1kg, lubricant 2kg.

[0058] First, the ABS high rubber powder, styrene acrylonitrile copolymer (SAN), and compatibilizer are fully mixed in a high mixer and then exported, and then put into a screw machine to extrude and granulate. The speed of the screw machine is 300-400rpm. The temperature is 200-220°C to make compatibilized masterbatch.

[0059] Then fully mix the compatibilizing masterbatch and other components in a high-speed mixer, then export them, and then put them into a screw machine to extrude and granulate. / Recycled PET resin composition. The performance of the ABS / regenerated PET resin composition was tested in the same way as in Example 1-2, and the results are shown in Table 2. From the results in Table 2, it can be seen that the ABS / regenerated PET resin compositions prepared in Example 3 and Exampl...

Abstract

The invention discloses an ABS (acrylonitrile-butadiene-styrene) / regenerated PET (polyethylene terephthalate) resin composition and a preparation method thereof. The composition comprises the following components: 15-60 wt% of ABS high glue powder, 5-25 wt% of styrene-acrylonitrile (SAN) copolymer, 5-50 wt% of regenerated PET, 1-10 wt% of compatilizer, 0.1-1% of antioxidant and 0.1-2% of lubricant. The preparation method comprises the following steps: thoroughly mixing the ABS high glue powder, SAN copolymer and compatibilizer in a high-speed mixer, discharging, putting the mixture into a screw extruder, extruding and granulating to obtain a compatilizing master batch; and thoroughly mixing the compatilizing master batch and the rest of the components in the high-speed mixer, thoroughly mixing, discharging, putting the mixture into the screw extruder, extruding and granulating to obtain the ABS / regenerated PET resin composition disclosed by the invention. By adding the styrene-acrylonitrile copolymer-glycidyl methacrylate terpolymer, the compatibility of the ABS and PET is effectively improved, so that the ABS / PET resin composition has high impact resistance.

Description

technical field [0001] The invention relates to an ABS / regenerated PET resin composition and a preparation method. Background technique [0002] With the continuous and rapid development of the plastic industry, plastic products have been widely used in various industries, but accompanied by an increasing number of plastic waste, resulting in a huge waste of energy. More and more attention has been paid to the recycling of waste plastics. [0003] As we all know, plastic raw materials are chemical products extracted from natural petroleum. Petroleum is the lifeblood of modern industry and a non-renewable natural resource. According to statistics from relevant departments, the annual plastic waste generated by a medium-sized city can meet the raw material needs of 20 small and medium-sized plastic enterprises. Therefore, recycled plastic is petroleum recycled. The use of waste plastics to melt and granulate can alleviate the contradiction between the supply and demand of p...
