Description
Technical Field
The invention belongs to the field of resin compositions and preparation thereof, and particularly relates to a noise-reducing, low-temperature impact-resistant, damp-heat aging-resistant PC/ASA resin composition and a preparation method thereof.
Background
PC (polycarbonate) resins are colorless and transparent, have excellent heat resistance, high strength and impact resistance, and are dimensionally stable, and are engineering plastics having a very wide range of applications. ASA (acrylonitrile-butyl acrylate-styrene copolymer) has excellent weather resistance, good processability and chemical stability, and is easy to mold. The blend of PC and ASA resin integrates the advantages of each component resin, and is widely applied to industries such as automobile industry, electronic and electric appliance industry, light industry and household appliances, textile, building and the like due to the excellent comprehensive performance of the blend. But the PC/ASA resin alloy has poor low-temperature impact toughness and long-term damp-heat aging resistance, and the obvious defect greatly limits the further broadening application of the product. Particularly in the fields of automobiles, household appliances and the like, the product has high requirements on low-temperature resistance toughness and long-term performance maintenance of damp and hot environments. Therefore, the improvement of the low-temperature toughness and the wet-heat aging resistance of the PC/ASA is of great significance.
In recent years, low noise resin has been receiving attention from both academic and industrial fields, and research on reduction of noise generated by friction between plastic parts has been gradually conducted. Therefore, the development of the noise reduction characteristic endowed with PC/ASA is also significant.
Chinese patent CN110330735A discloses a cold-resistant ASA material and a preparation method thereof, which is prepared from the following raw materials in parts by mass: 60% -70% of SAN resin; 20-30% of ASA rubber powder; 5% -15% of PC resin; 1-10% of low-temperature impact toughness improver; 1 to 10 percent of compatilizer; 1 to 5 percent of other processing aids; wherein the low-temperature impact toughness improver is one or a mixture of more than two of n-butyl acrylate-glycidyl ester, acrylic ester, acrylate butadiene styrene core-shell copolymer and organosilicon toughening agent. The ASA material has excellent low-temperature impact property, good weather resistance and good processing and forming properties. However, the ASA material has poor resistance to wet heat aging. Chinese patent CN102229736A discloses a light noise-reducing modified ABS material, in which a hollow particle type inorganic filler is added in the formula, and the special structure of the hollow particle enables the material to have a certain noise-reducing function, but the noise-reducing function can not meet the use requirements in the fields of automobile exterior trimming parts, electronic appliances, household appliances and the like.
