Problems solved by technology

However, due to the aging effect of recycled ABS resin, its mechanical properties, especially the impact resistance, are far inferior to those of new ABS materials. At the same time, recycled ABS resin contains more or less other plastics such as PC, PP, PE, etc. Among them, non-polar resins such as PP, PE and ABS are incompatible and delaminated, easy to migrate and enrich the surface, thereby reducing the polarity of the recycled ABS resin surface, making it difficult to paint the recycled ABS resin, that is, the coated polar paint is easy to fall off
The above defects limit the application of recycled ABS materials
Chinese patents CN1646280 and CN101016401 proposed a method for improving the mechanical properties of recycled ABS, but did not mention how to solve the problem of difficult painting on the surface of recycled ABS
The invention proposes a toughened and enhanced paintable recycled ABS and a preparation method thereof, which not only improves the mechanical properties of recycled ABS, but also solves the problem that recycled ABS is difficult to paint

preparation example Construction

[0017] A method for preparing toughened and enhanced paintability regenerated ABS, comprising the following steps: uniformly mixing the above-mentioned various materials, and then melting and extruding at 190-220°C.

[0018] The toughening agent is at least one of ABS high rubber powder, EVA, SEBS, SBS, and EPDM. The compatibilizer is maleic anhydride grafted polyolefin. The maleic anhydride grafted polyolefin is one of PP-g-MAH and PE-g-MAH. In the maleic anhydride grafted polyolefin, the grafting ratio of maleic anhydride is ≥5%. The filler includes calcium carbonate, talcum powder, wollastonite, barium sulfate and kaolin. The antioxidant is at least one of hindered phenol antioxidants and phosphite antioxidants.

Abstract

The invention discloses a toughening and reinforcing paintable reclaimed ABS (Acrylonitrile-Butadiene-Styrene) which consists of the following raw materials in part by weight: 60-90 parts of recycled ABS, 5-20 parts of toughening agent, 1-6 parts of compatilizer, 1-15 parts of filler and 0.1-1 part of antioxidant. The reclaimed ABS aggregates provided by the invention have excellent mechanical property and painting property.

Description

technical field [0001] The invention relates to a toughened and enhanced paintable regenerated ABS and a preparation method thereof. Background technique [0002] ABS resin is the abbreviation or abbreviation of acrylonitrile, butadiene and styrene copolymer (Acrylonitrile-Butadiene-Styrene). ABS resin is a thermoplastic polymer material with high strength, good toughness, and easy processing and molding. hard hat etc. Since butadiene in ABS resin is prone to ultraviolet light degradation, the surface of many ABS resin products will be coated with paint (usually acrylic or polyurethane paint), which not only satisfies the decoration of the product but also reduces the photoaging of the product. With the shortage of petroleum resources and the increasingly stringent environmental protection, the application of recycled ABS resin is gradually increasing. Due to the extremely fierce market competition, many ABS product manufacturers have begun to use recycled ABS materials t...
