Antibacterial glass fiber reinforced AS (acrylonitrile-styrene copolymer) composite material and preparation method thereof

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 ...

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 treatment steps, complex process and further cost increase

In addition, the Chinese patent CN201110138482 uses AS, glass fiber, and coupling agent as raw materials, and by adjusting the screw combination, a reinforced AS composite material with a relatively uniform density is prepared, but the tensile strength of the prepared composite material is 100-110MPa, and the impact strength At 5.5-6.5kJ / m 2 , the performance is also lower
