Problems solved by technology

[0002] NPG-PET is directly esterified and polycondensed from neopentyl glycol, ethylene glycol, terephthalic acid, etc. It is a new transparent resin with scratch resistance, aging resistance, chemical resistance and high gloss. , high fluidity, but compared with CHDM-PET (1,4-cyclohexanedimethanol, ethylene glycol, terephthalic acid, etc. directly esterified and polycondensed), the toughness is poor
ABS resin has a relatively low price, which makes it irreplaceable compared with other resins, but its strength and weather resistance limit the application of ABS.

preparation example Construction

[0038] Please refer to figure 1 , the present invention further provides a kind of preparation method of above-mentioned ABS / NPG-PET alloy material, comprises the following steps:

[0039] S1, weigh ABS, NPG-PET and ethylene acrylate elastomer, place these three resins in a high-speed mixer preheated to 60-65°C and stir, remove the moisture in the resin, and obtain resin mixture a;

[0040] S2, copper powder or silver powder, anti-UV agent, antioxidant and amphiphilic polymer additives are mixed evenly, and then put into the high-speed mixer in step S1, stirred until uniform, and mixture b is obtained;

[0041] S3, put the obtained mixture b into the hopper of the twin-screw extruder, and granulate through melt extrusion, wherein the temperatures in the first zone to the ninth zone of the twin-screw extruder are: 210±10°C, 220±10°C, 220±10℃, 220±10℃, 210±10℃, 210±10℃, 210±10℃, 220±10℃, 230±10℃, the die head temperature is 230±10℃, the host speed is 300rpm.

Embodiment 1

[0043] Weigh 70 parts by weight of ABS, 30 parts by weight of NPG-PET, and 5 parts by weight of ethylene acrylate elastomer, and stir these three resins in a high-speed mixer that has been preheated to 65°C to remove the moisture to obtain resin mixture a; 0.6 parts by weight of copper powder, 0.4 parts by weight of anti-UV agent, 0.3 parts by weight of antioxidant and 0.3 parts by weight of amphiphilic polymer additives are mixed evenly, and then put into the high-speed mixing in step S1 Put the obtained mixture b into the hopper of the twin-screw extruder, and granulate through melt extrusion, wherein the temperature of the first zone to the ninth zone of the twin-screw extruder is respectively: 210 ±10℃, 220±10℃, 220±10℃, 220±10℃, 210±10℃, 210±10℃, 210±10℃, 220±10℃, 230±10℃, the die temperature is 230± 10°C, host speed 300rpm.

Embodiment 2

[0045] It is basically the same as Example 1, except that 7 parts by weight of ethylene acrylate elastomer is added.

Abstract

The invention provides an ABS / NPG‑PET alloy material and a preparation method thereof. The ABS / NPG-PET alloy material is characterized in that it comprises the following components in parts by weight: 55-90 parts by weight of ABS; 10-45 parts by weight of NPG-PET; 5-10 parts by weight of ethylene acrylic acid Ester elastomer; 0.1-2 parts of weight anti-UV agent; 0.1-1 parts of weight of antioxidant; 0.5-2 parts of weight of copper powder or silver powder; 0.1-0.5 parts of weight of amphiphilic polymer additives, wherein, the Both ends of the amphiphilic polymer additive have polar groups that can react with ester groups, carboxyl groups, and hydroxyl groups and adsorb with copper powder or silver powder.

Description

technical field [0001] The invention relates to an ABS / NPG-PET alloy material and a preparation method thereof. Background technique [0002] NPG-PET is directly esterified and polycondensed from neopentyl glycol, ethylene glycol, terephthalic acid, etc. It is a new transparent resin with scratch resistance, aging resistance, chemical resistance and high gloss. , High fluidity, but compared with CHDM-PET (1,4-cyclohexanedimethanol, ethylene glycol, terephthalic acid, etc., which are directly esterified and polycondensed), the toughness is poor. ABS resin has a relatively low price, which makes it irreplaceable compared with other resins, but its lack of strength and weather resistance limits the application of ABS. Blending ABS and NPG-PET to prepare ABS / NPG-PET alloy not only retains the original performance advantages of ABS and NPG-PET, but also gives ABS / NPG-PET alloy new properties by changing the aggregate structure, making Its comprehensive performance is more excel...
