Problems solved by technology

However, the mechanical properties and weather resistance of ABS resin are poor. In order to make up for these shortcomings, ABS resin can be blended with other resins to prepare alloys. While maintaining the original excellent properties of ABS, it can effectively make the deficiencies of ABS resin. improve

preparation example Construction

[0025] The present invention also provides a method for preparing the electroplatable ABS / polyester blended alloy, which specifically includes the following steps:

[0026] S1, dry ABS resin and neopentyl glycol modified PETG copolyester;

[0027] S2, weigh the dried ABS resin, neopentyl glycol-modified PETG, rubber, solubilizer, and antioxidant according to the proportion, put the weighed materials into a high-speed mixer, and mix them evenly;

[0028] S3, adding the mixed materials in step S2 to a twin-screw extruder, controlling the processing temperature at 160°C to 250°C, and the screw speed at 100 to 600rpm, melt blending, extruding and granulating through the twin-screw extruder, namely The electroplatable ABS / polyester blend alloy of the present invention is obtained.

[0029] In step S1, the ABS resin and the neopentyl glycol-modified PETG copolyester can be put into a drying oven to dry. Dry the ABS resin at 75-85 degrees Celsius for 2-4 hours, and dry the neopenty...

Embodiment 1

[0033] An electroplatable ABS / polyester blended gold, which consists of the following components by weight percentage: 65 parts of recycled ABS resin, 25 parts of neopentyl glycol modified PETG copolyester, high rubber powder 60P 5 3 parts, 3 parts of SBG001, 1 part of antioxidant 1010; The PETG copolyester modified by neopentyl glycol is composed of terephthalic acid, ethylene glycol, 1,4-cyclohexanedimethanol and neopentyl glycol Alcohol copolymerization reaction.

[0034] The preparation method of the electroplatable ABS / polyester blended alloy: dry the recovered ABS resin and neopentyl glycol modified PETG copolyester; weigh the recovered ABS resin, neopentyl glycol modified Add PETG copolyester, high rubber powder 60P, SBG001 and antioxidant 1010 into a high-speed mixer, and mix and stir for 1 to 7 minutes at room temperature to obtain a mixed material; put the mixed material into a twin-screw extruder In the process, the processing temperature is controlled at 210-250 d...

Embodiment 2

[0036] It is basically the same as Example 1, except that 6 parts by weight of SBG001 are added to obtain the electroplatable ABS / polyester blend gold B of the present invention.

Abstract

The invention relates to an electroplatable ABS / polyester blended alloy and a preparation method thereof. The electroplatable ABS / polyester blended alloy comprises ABS resin and neopentyl glycol modified PETG copolyester, wherein the ABS resin is non-electroplating-grade or recovered ABS resin. By means of an ordinary conventional method, all raw materials are weighed in proportion, processes suchas uniform mixing, melt extrusion, granulation are performed, the blended alloy material with enhanced shock resistance and weather resistance can be obtained, and the blended alloy material is electroplatable, has processing conditions similar to those of ABS resin and can meet the adhesion test standard.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an electroplatable ABS / polyester blended alloy and a preparation method thereof. Background technique [0002] ABS resin (acrylonitrile-butadiene-styrene copolymer, ABS is the acronym for Acrylonitrile ButadieneStytene) is one of the five major synthetic resins, its impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical Excellent performance, also has the characteristics of easy processing, stable product size, good surface gloss, etc., easy to paint and color, and can also carry out secondary processing such as surface metal spraying, electroplating, welding, hot pressing and bonding, etc., widely used in It is a widely used thermoplastic engineering plastic in industrial fields such as machinery, automobiles, electronic appliances, instrumentation, textiles and construction. However, the mechanical properties an...
