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 polypropylene with odor and low VOC requirements

Abstract

The invention provides a low-odor glass fiber reinforced polypropylene composite material which is prepared from the following raw materials in parts by weight: 60-90 parts of polypropylene, 5-40 parts of a short glass fiber reinforcing agent, 3-10 parts of an interface compatilizer, 1-5 parts of a first deodorant, 1-5 parts of a second deodorant and 0.1-1 part of an antioxidant. The invention further provides a preparation method of the low-odor glass fiber reinforced polypropylene composite material. According to the composite material, a glass fiber is adopted for modification in material filling, in addition, under co-assistance of the interface compatilizer and the deodorant, the mechanical properties of the material are further improved, the odor of the composite material can be relatively effectively controlled, and particularly the composite material is outstanding in a high-content glass fiber system and has an odor grade approximate to that of a composite material with a lowglass fiber content.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a glass fiber reinforced polypropylene composite material, in particular to a low-odor glass fiber reinforced polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene PP 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 glass fiber system can effectively make up for the performance defects of polypropylene, thereby further reducing costs. [0003] With the current trend of automobile lightweight, the use of glass fiber reinforced polypropylene system has been more and more used in various parts of automobiles, such as front frame, bumper and so on. More and more glass fiber reinforced polypropylene systems are entering the car, which brings another problem-odor...
