Low-odor sterilization reinforced ABS (acrylonitrile butadiene styrene) automobile rearview mirror frame material and method for preparing same

Abstract

The invention discloses a low-odor sterilization reinforced ABS (acrylonitrile butadiene styrene) automobile rearview mirror frame material and a method for preparing the same. The low-odor sterilization reinforced ABS automobile rearview mirror frame material comprises, by weight, ABS, chopped glass fibers, toughening agents, compatilizers, grafting and coating fillers, heat stabilizers, low-volatility matter adsorbents, coating treatment clastic enzymes, nano-photocatalysts, antioxidants, anti-ultraviolet absorbents, anti-floating cellosolve and lubricants. The low-odor sterilization reinforced ABS automobile rearview mirror frame material and the method have the advantages that the low-volatility matter adsorbents are extremely high in adsorption capacity, and low-volatility harmful gasgenerated by components formed from composite materials can be effectively prevented from being outwardly diffused; generated trace low-volatility harmful gas can be decomposed by the coating treatment clastic enzymes and the nano-photocatalysts to obtain carbon dioxide and water which are harmless, and the low-odor sterilization reinforced ABS automobile rearview mirror frame material is excellent in physical and mechanical property, heat aging resistance and weather resistance and low in odor and TVOC (total volatile organic compound) content, is stress-crack-resistant, corrosion-resistant,shock-resistant and scratch-resistant and can be used for producing automobile rearview mirror frames.

Description

technical field [0001] The invention relates to the technical field of modification of ABS materials, in particular to a low-odor sterilization reinforced ABS automobile rearview mirror frame material and a preparation method.

Due to its good comprehensive performance, ABS material is widely used in the manufacture of automotive interior parts. [0003] The rearview mirror frame is set in the middle of the cab, through which the driver looks backward; the rearview mirror frame material for automobiles is generally made of glass fiber reinforced nylon, which is used to frame the outside of the cab. Benzene and aldehydes will be volatilized in ABS materials...

AI Technical Summary

Problems solved by technology

Odor inhibitors rely on their own huge specific surface area to adsorb low-volatility small molecules, but the adsorption is saturated. The antibacterial agent used in this invention is an inorganic antibacterial agent, and the efficiency is low. If the sterilization rate reaches 99.9%. , the amount added needs to be large, which will affect the physical and mechanical properties of the substrate

[0005] Chinese invention patent application CN103724922A discloses a low-odor glass fiber reinforced ABS composition and its preparation method. The application uses jellyfish particles with high-melt foaming PP as the carrier as the air stripping agent; the small molecules volatilized in the ABS material Substances mainly include benzene series and aldehyde series. After water enters the resin, the aldehyde series in ABS can be taken away, and benzene series are insoluble in water and cannot be removed with the evaporation of water. Although they can be absorbed by foaming PP, However, the specific surface area of ​​this material is relatively small. If the adsorption effect is to be enhanced, the dosage is required to be large, which has a great impact on the mechanical properties of the material. This patent application has certain limitations.
