High-performance, anti-static and anti-bacterial glass fiber reinforced AS (acrylonitrile-styrene) composite material and preparation method thereof

Abstract

The invention provides a high-performance, anti-static and anti-bacterial glass fiber reinforced AS (acrylonitrile-styrene) composite material and a preparation method thereof. The high-performance, anti-static and anti-bacterial glass fiber reinforced AS composite material comprises components in percentage by weight as follows: 43%-88.4% of AS resin, 10%-30% of glass fiber, 1%-5% of a compatilizer, 0.1%-1% of a coupling agent, 10%-15% of an anti-static agent, 0.5%-2% of an anti-bacterial agent and 0.1%-3% of an assistant, wherein the compatilizer adopts PMMA (polymethyl methacrylate), and the coupling agent adopts a silane coupling agent. The substrate of the composite material is AS resin, and the composite material has the advantages of excellent performance, low cost, simple preparation technology and the like; and besides, PMMA is taken as the compatilizer, so that not only is bonding force between the glass fiber and the AS resin strengthened, but also the PMMA is also suitable for enhancing a fiber and resin composite material system with the similar property.

Description

technical field [0001] The invention belongs to the field of modified plastics, in particular to a high-performance antistatic and 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...

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
