Glass-fiber-reinforced modified resin ASA composite material with low smell and preparation method thereof

Abstract

The invention provides a glass-fiber-reinforced modified resin ASA composite material with a low smell. The glass-fiber-reinforced modified resin ASA composite material comprises, by weight, 60-90 parts of modified resin ASA, 5-40 parts of short glass fiber reinforcements, 3-10 parts of interface compatilizer, 1-5 parts of first deodorant, 1-5 parts of second deodorant and 0.1-1 part of antioxygen. The invention further provides a preparation method of the glass-fiber-reinforced modified resin ASA composite material. The glass-fiber-reinforced modified resin ASA composite material has the advantages that glass fibers are used for modification, and with the joint aid of the interface compatilizer and the antioxygen, the smell of the composite material can be controlled effectively while themechanical property of the material is improved further; the composite material has outstanding performance in a high-content glass fiber system, and the smell is not quite different from the smell of a low-glass-fiber-content glass fiber system.

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...

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
