Problems solved by technology

The compound increases the Vicat softening temperature, but the flexural modulus is too low, only 5000MPa; and due to the addition of a large amount of ABS and SMA, the manufacturing cost increases
In Chinese patents CN1362443A and CN1352212A, methacrylic acid-butadiene-styrene copolymer (MBS), AS, SMA, ABS and glass fiber are used as raw materials to blend the AS compound, but it increases the glass fiber Dipping treatmen

Embodiment Construction

[0036] The present invention provides embodiment 1-6 and comparative example 1-6, and the preparation method of embodiment and comparative example is identical, and concrete steps are as follows:

[0037]S1. Take the AS resin, compatibilizer, coupling agent, antibacterial agent and auxiliary agent in each embodiment or each comparative example by weighing the percentage by weight listed in the following table 1, and mix them in a high mixer for 1-3min; Mix evenly, obtain premix; Wherein, embodiment and comparative example select the coupling agent of corresponding specification with reference to Table 2

[0038] S2. Put the premix into the main feeding port of the twin-screw extruder, and add the weight percentage shown in the following table 2 from the side feeding port to weigh the glass fiber corresponding to each embodiment or each comparative example, Melt extrusion, granulation and drying are carried out to obtain the glass fiber reinforced AS composite material.

Abstract

The invention provides an antibacterial glass fiber reinforced AS (acrylonitrile-styrene copolymer) composite material and a preparation method thereof. The composite material comprises the following components by weight percent: 55.4-88.4% of AS resin, 10-30% of glass fibers, 1-5% of compatilizer, 0.1-1% of coupling agent, 0.5-2% of antibacterial agent and 0.1-3% of auxiliaries, wherein the compatilizer is PMMA (polymethyl methacrylate); the coupling agent is a silane coupling agent. The composite material has the advantages and positive effects that with the AS resin as the matrix, the composite material has the advantages of excellent properties, low cost, simple preparation process, and the like; used as the compatilizer, PMMA is not only limited to reinforcing the binding forces between the glass fibers and the AS resin but is also suitable for reinforcing fiber and resin composite material systems with similar properties.

Description

technical field [0001] The invention belongs to the field of modified plastics, and in particular relates to an antibacterial glass fiber reinforced AS composite material and a preparation method thereof. Background technique [0002] Acrylonitrile-styrene resin, namely AS resin, is a kind of thermoplastic made by copolymerization of styrene (St) and acrylonitrile (AN) as raw materials. AS resin has excellent performance and excellent Dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, molding processing and mechanical processing are good, and it is an important engineering plastic. [0003] Glass fiber reinforced plastics have the advantages of high specific strength, corrosion resistance, heat insulation, and low molding shrinkage. Using glass fiber reinforcement can greatly improve the tensile properties of plastics. Adding glass fiber to AS resin can enhance the strength and thermal deformation resistance of AS resin, and can ...
