Problems solved by technology

The traditional solution, as described in CN201310308220.6, uses nano-zinc oxide and nano-titanium dioxide to achieve low odor and low VOC by changing the mass ratio of the added amount and vacuuming it out. Although it can achieve its ideal effect, However, nano-zinc oxide and nano-titanium dioxide are expensive, and it is not feasible to achieve low-odor and low-VOC effects by adding these two additives in actual factory production. Not only that, but this method can only reduce some The small molecular substances are extracted, and the other substances with higher boiling points still remain in the material, which cannot be really eradicated; CN201010543461.5 also uses a similar solution, using a compound deodorant to achieve the purpose of deodorization and low VOC , but the use of zinc ricinoleate as the leading deodorant has a significant effect on the removal of small sulfur molecules. The effectiveness of other small molecules such as benzene, aldehydes and ketones still needs to be studied, so it cannot really achieve low Glass fiber reinforced modified resin ASA with odor and low VOC requirements

Abstract

The invention provides a low-odor glass fiber reinforced modified resin ASA composite material, which is prepared from the following raw materials in parts by weight: 60-90 parts by weight of modified resin ASA, 5-40 parts by weight of short glass fiber reinforcement, 3-10 parts by weight of the interface compatibilizer, 1-5 parts by weight of the first deodorant, 1-5 parts by weight of the second deodorant and 0.1-1 parts by weight of the antioxidant. The invention also provides a preparation method of the glass fiber reinforced modified resin ASA composite material. The present invention uses glass fibers for modification in material filling, and with the common assistance of interfacial compatibilizer and deodorant, while further improving the mechanical properties of the material, it can more effectively control the odor of the composite material, especially in The high glass fiber content system is outstanding, and the odor level is not much different from the low glass fiber content.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a glass fiber reinforced modified resin ASA composite material, in particular to a glass fiber reinforced modified resin ASA composite material with low odor and a preparation method thereof. Background technique [0002] Modified resin ASA is a widely used general-purpose plastic. It has excellent comprehensive performance, molding processability, and relatively low price. It occupies a leading position in plastics and is widely used in daily life. Adding the glass fiber system can effectively make up for the performance defects of the modified resin ASA, thereby further reducing the cost. [0003] With the current trend of automobile lightweight, the use of glass fiber reinforced modified resin ASA system has been more and more used in various parts of automobiles, such as rearview mirrors, bumpers and so on. More and more glass fiber reinforced modified resin ASA systems have e...
