Problems solved by technology

[0003] The mechanical properties of glass fiber reinforced AS largely depend on the bonding strength of AS and glass fiber. Due to the poor interface bonding between resin and glass fiber, the reinforcing effect of glass fiber cannot be fully exerted. The strength, toughness, and Poor performance such as heat resistance
[0004] 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 chemical products The warehouse exploded and caught fire, causing major personal accidents

preparation example Construction

[0033] The present invention provides Examples 1-5 and Comparative Examples 1-5, wherein the preparation methods of Examples 1-5 are the same, and the specific steps are as follows:

[0034] An antistatic glass fiber reinforced AS composition, the component formula of which is shown in Table 1.

[0035] A preparation method of the described antistatic glass fiber reinforced AS composition comprises the steps:

[0036] (1) Weigh AS resin, glass fiber, compatibilizer, antistatic agent, coupling agent and auxiliary agent in each example by weighing the parts by weight listed in Table 1 below, and mix them in a high-mixer for 1-3min ; Mix evenly to obtain a premix;

[0037] (2) Place the premix in the main feeding port of the twin-screw extruder, add glass fiber from the side feeding port, carry out melt extrusion, pelletize and dry. Its performance was measured, and the specific data are listed in Table 3.

Abstract

The invention provides an anti-static glass fiber reinforced AS composition and a preparation method thereof. The anti-static glass fiber reinforced AS composition comprises, by weight parts, 44-78 parts of AS resin, 10-20 parts of glass fiber, 5-10 parts of compatilizer, 0.1-1 part of coupling agent, 10-15 parts of anti-static agent and 0.1-1 part of auxiliaries. The AS resin is a copolymer of acrylonitrile and styrene, and the glass fiber is one or two or more of long glass fiber and chopped glass fiber. According to the anti-static glass fiber reinforced AS composition, acrylate polymer or copolymer is used to serve as the compatilizer, so that the interface state between the glass fiber and the resin can be effectively changed, the interfacial binding power is improved, and thus the performance of a composite material is improved.

Description

technical field [0001] The invention belongs to the field of materials, in particular to an antistatic glass fiber reinforced AS composition and a preparation method thereof. Background technique [0002] Glass fiber reinforced acrylonitrile-styrene (AS) has good application value in the field of household appliances due to its good processability, dimensional stability and tensile strength, such as axial flow, cross flow and centrifugal fan blades in air conditioners, etc. . The performance of glass fiber reinforced AS parts directly affects the quality of air conditioners and is closely related to our daily life. [0003] The mechanical properties of glass fiber reinforced AS largely depend on the bonding strength of AS and glass fiber. Due to the poor interface bonding between resin and glass fiber, the reinforcing effect of glass fiber cannot be fully exerted. Heat resistance and other properties are poor. [0004] As the AS material is a poor conductor of electricity...
