A low odor, antistatic glass fiber reinforced AS composition and preparation method thereof

Abstract

The invention discloses a low-smell and antistatic fiberglass reinforced AS (Styrene Acrylonitrile) combination and a preparation method thereof. The low-smell and antistatic fiberglass reinforced AS combination comprises 44.4-76.4 percent of AS resin, 10-30 percent of fiberglass, 1-5 percent of a compatilizer 1, 1-5 percent of a compatilizer 2, 1-5 percent of medusa particle, 10-15 percent of an antstatic agent and 0.1-3 percent of an assistant. The preparation method comprises the steps as follows: the AS resin, compatilizers 1 and 2, the antistatic and the assistant are mixed in a high mixing machine for 1-3 minutes, placed in a main feeding hole of a dual-screw extruder, added with fiberglass and the medusa particle from a side feeding hole, molten, extruded, pelletized and dried to obtain the low-smell and antistatic fiberglass reinforced AS combination. According to the invention, an AS blend of the maleic anhydride graft is used as the compatilizer 1 and can improve the interface coupling effect of the AS and the fiberglass; the maleic anhydride graft is used as the compatilizer 2 and can greatly improve the compatibilityof the composite material; the medusa particles adopting high-melts foamed PP as a carrier is used as a stripping agent, and various kinds of volatile small molecules and organic compounds which are generated during processing can be effectively removed, so that the prepared fiberglass reinforced AS combination has the characteristics of low smell and good mechanical performance, and the antistatic effect is good by virtue of the added antistatic agent.

Description

technical field [0001] The invention relates to the field of modified plastics, in particular to a low-odor, antistatic glass fiber reinforced AS composition and a preparation method thereof. Background technique [0002] Styrene-acrylonitrile resin (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 a huge market. [0004] There are many re...

However, these additives have a great influence on the mechanical properties of AS alloy materials, especially the impact

[0007] The above-mentioned methods solve 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 reduce the odor. result of action

Moreover, since AS material is a poor conductor of electricity, it is easy to accumulate static charge during processing and use. When the static charge accumulates to a certain extent, static electricity will cause the material to absorb dust, cause material damage, and may also generate static spark discharge, causing The chemical product warehouse exploded and caught fire, causing major personal accidents
