Description
Technical Field
The invention belongs to the field of ASA resin, and particularly relates to a scratch-resistant low-temperature-impact-resistant ASA resin composition and a preparation method thereof.
Background
ASA (acrylonitrile-styrene-acrylate) resin, also known as AAS resin, is a ternary graft copolymer synthesized from acrylate rubber, acrylonitrile, and styrene. German Basff company realizes the industrial production in 1962 at first, and then other companies abroad can obtain the industrial technology in sequence, and the research on the technology is started later in China. Compared with ABS resin, because the ASA resin selects acrylic rubber without a double-bond structure to replace polybutadiene rubber with an unsaturated double-bond structure in the ABS resin, the aging resistance of the ASA resin is far better than that of the ABS resin, the ASA resin can be directly used in the open air, and the ABS resin needs to be subjected to post-processing treatment such as spraying and electroplating if exposed, which is the original intention for developing the ASA resin. Meanwhile, the ASA resin also has excellent mechanical property, thermal stability, good processing formability and colorability. At present, the ASA resin is widely applied to the fields of building materials, automobile exterior trimming parts, electronic and electrical engineering exterior trimming parts, outdoor articles, sports equipment and the like, such as house wall panels, co-extruded plastic tiles, outdoor fences, automobile rearview mirror shells, heat dissipation grids, door outer triangular blocks, upright column plates, empennage decorative plates, satellite antennas, mower shells and the like.
Although the aging resistance of ASA resin is far better than that of ABS resin, the glass transition temperature of polyacrylate rubber is about 30 ℃ higher than that of polybutadiene rubber, so the low temperature resistance of ASA resin is obviously worse than that of ABS resin. This disadvantage of ASA resins limits their wider use. Especially for the automobile industry, the low-temperature impact toughness of the parts is strictly required, and the low-temperature impact toughness of the common ASA resin is difficult to meet. In addition, ASA resins often have scratch resistance when applied to exterior automotive parts.
In conclusion, it is important to design an ASA resin with scratch resistance and low-temperature impact resistance. However, no reports on the technical literature and patents of ASA resins having both excellent scratch resistance and low-temperature impact resistance have been found so far.
Disclosure of Invention
The invention aims to solve the technical problem of providing a scratch-resistant low-temperature impact-resistant ASA resin composition and a preparation method thereof, which not only greatly improve the scratch-resistant and low-temperature impact-resistant toughness, but also have excellent comprehensive properties of rigidity, heat resistance, weather resistance and the like.
The invention provides a scratch-resistant low-temperature-impact-resistant ASA resin composition, which comprises the following components in parts by weight:
The ASA rubber powder has a weight average relative molecular mass of 100,000-500,000, preferably 200,000-300,000, and a butyl acrylate rubber content of 20-70%, preferably 45-65%.
The SAN resin has a weight average relative molecular mass of 90,000-300,000, preferably 120,000-200,000, and a melt flow rate of 10-50g/10min, preferably 10-35g/10 min.
The heat-resistant agent is an N-phenylmaleimide polymer.
The processing aid comprises one or more of an antioxidant, a light stabilizer, a lubricant and a toner.
The antioxidant is a mixture of hindered phenol antioxidant and phosphite antioxidant; the light stabilizer is a benzotriazole UV absorbent and high molecular weight hindered amine with the mass ratio of 1: 1; the lubricant is pentaerythritol stearate.
The invention also provides a preparation method of the scratch-resistant low-temperature impact-resistant ASA resin composition, which comprises the following steps:
premixing the raw materials in a high-speed mixer according to the proportion; and carrying out melt extrusion on the obtained premix through a double-screw extruder, and cooling and granulating to obtain the scratch-resistant low-temperature impact-resistant ASA resin composition.
The extrusion temperature is 190 ℃ and 250 ℃, and the screw rotation speed is 300 ℃ and 700 r/min.
The invention also provides application of the scratch-resistant low-temperature-impact-resistant ASA resin composition.
Advantageous effects
According to the invention, by introducing the graft copolymer of styrene and ethylene, the ASA resin has excellent low-temperature impact toughness and scratch resistance. As for the copolymerization modifier, the styrene part provides compatibility with SAN and ASA rubber powder matrix resin, so that the styrene part has good dispersibility in the matrix resin. The polyethylene part improves the surface property of the ASA resin to ensure that the ASA resin has excellent scratch resistance, and can endow low-temperature impact property due to the lower glass transition temperature of the polyethylene compared with the ASA resin. The product of the invention has excellent comprehensive properties of scratch resistance, low-temperature impact resistance, toughness, mechanical property and the like, and is very suitable for being applied to exterior parts such as automobile grilles, upright column plates, empennage decorative plates and the like. In addition, the preparation method has the advantages of simple process and low cost, and is very suitable for industrial production.
