Low-odor enhanced-glassfibre ABS composition and preparation method thereof

Abstract

The invention discloses a low-odor enhanced-glassfibre ABS composition and a preparation method thereof. The composition comprises the following components: 54-86.4 percent of ABS resin, 10-30 percent of glassfibre, 11-5 percent of a compatilizer I, 21-5 percent of a compatilizer II, 1-5 percent of medusa grains, and 0.1-3 percent of an additive. The method comprises the following steps: mixing the ABS resin, the compatilizers, and the additive in a high mixing machine for 1-3 min; uniformly mixing, placing in a main feed inlet of a double-screw extruder, adding the medusa grains and glassfibre from a lateral feed inlet, and performing melt extrusion, pelletization and drying, thereby obtaining the ABS composition. According to the invention, the compatilizer I adopts an ABS co-mixer grafted with maleic anhydride to increase the interface coupling function of the ABS and the glassfibre, thereby greatly improving the ABS mechanical strength; besides, the compatilizer II grafted with the maleic anhydride greatly improves the compatibility of the composite. The medusa grains taking HMSPP as a carrier are adopted as an air lift agent, various volatiled small molecules and organic compounds generated during the manufacturing process can be removed. The prepared ABS composition has the advantages of low odor, excellent mechanical performance and the like.

Description

technical field [0001] The invention relates to a glass fiber reinforced ABS composition, in particular to a low-odor glass fiber reinforced ABS composition and a preparation method thereof. Background technique [0002] Styrene-butadiene-acrylonitrile (ABS) resin combines the rigidity and heat resistance of acrylonitrile, the gloss and processability of polystyrene, and the impact resistance of polybutadiene, and is widely used in household Electrical appliances, office equipment, instrumentation, transportation, building materials, daily appliances and packaging materials and other fields. The use of glass fiber to reinforce ABS can further improve the mechanical properties of the composite material and increase its heat resistance temperature. However, due to the strong odor of glass fiber reinforced ABS composite materials, its application in automobiles, home appliances and other fields is limited. [0003] There are many reasons for the smell of glass fiber reinforce...

Problems solved by technology

Disclosed a kind of ABS alloy molding of smell improvement among USP6297307, by adding a mixture of zinc oxide, magnesium oxide and at least one epoxy compound, although this method can improve smell, but these additives are harmful to ABS alloy material The mechanical properties, especially the impact have a great influence

[0006] The above-mentioned method solves the odor problem of the material to varying degrees. However, the above-mentioned method is only aimed at the influence of a certain component on the odor, thereby adding an adsorbent to Reduces odor, but in fact material odor is the result of the interaction of multiple component odors
