preparation example Construction

[0038] The present invention provides embodiment 1-4 and comparative example 1-4, and the preparation method of embodiment and comparative example is identical, and concrete steps are as follows:

[0039] S1, prepare jellyfish pellets according to the following steps:

[0040] (1) Fully mix the polypropylene and the mineral filler by weight percentage, extrude the strip mixture in the extruder, then chop the strip mixture to make polypropylene pre-expanded particles;

[0041] (2) Using water as a foaming agent, foaming the polypropylene pre-expanded particles to prepare expanded polypropylene with high melt strength;

[0042] (3) Mixing foamed polypropylene with high melt strength and 50%-98% water in a high-speed mixer for 5-10min to prepare jellyfish pellets with different water contents;

[0043] S2. Take AS resin, compatibilizer 1, compatibilizer 2, antistatic, antibacterial agent and auxiliary agent by weight percentage shown in Table 1 and mix in high mixer for 1-3min; mi...

Embodiment 4

[0057] Comparing Example 4 with Comparative Example 4, the water content of jellyfish pellets in Comparative Example 4 is lower, and the prepared glass fiber reinforced AS composition has a poorer odor and higher volatile matter content.

Abstract

The present invention provides a low-odor anti-static antibacterial-glass-fiber-reinforced AS composition and a preparation method thereof, the composition comprises the following components by weight: 39-79% of AS resin; 10-30% of glass fiber; 1-5% of a compatibilizer 1; 1-5% of a compatibilizer 2; 1-5% of water masterbatch; 10-15% of an antistatic agent and an antibacterial agent; and 0.1-3% of additives; the water masterbatch comprises the following components by weight: 1%-49% of polypropylene; 50%-98% of water and 0.1-5% of a mineral filler; the compatibilizer 1 is a maleic anhydride grafted AS mixture, and the compatibilizer 2 is polypropylene grafted with maleic anhydride PP-g-MAH. A matrix of the low-odor anti-static antibacterial-glass-fiber-reinforced AS composition is the AS resin, the low-odor anti-static antibacterial-glass-fiber-reinforced AS composition has the advantages of excellent performance, low cost, simple preparation process, and the like, the matters grafted with maleic anhydride are used as the compatibilizers, the compatibility of composite materials can be greatly increased, and the low-odor anti-static antibacterial-glass-fiber-reinforced AS composition is used for enhancement of fiber and resin composite material systems having similar nature.

Description

technical field [0001] The invention belongs to the field of modified plastics, and in particular relates to a high-performance glass fiber reinforced AS composite material and a preparation method thereof. Background technique [0002] Styrene-acrylonitrile resin (hereinafter referred to as AS) is a hard, transparent material. The styrene component makes AS hard, transparent and easy to process; the acrylonitrile component makes AS chemically and thermally stable. AS has strong load bearing capacity, chemical reaction resistance, thermal deformation resistance and geometric stability. Adding glass fiber additives can increase strength and thermal deformation resistance, and reduce thermal expansion coefficient. [0003] However, due to the strong odor of glass fiber reinforced AS composite materials, its application in the fields of automobiles and home appliances is limited; therefore, a low-odor glass fiber reinforced AS composite material has been developed, which has ...
