Low-odor, anti-static and anti-bacterial glass fiber reinforced AS (acrylonitrile-styrene) composition and preparation method thereof

Abstract

The invention provides low-odor, anti-static and anti-bacterial glass fiber reinforced AS (acrylonitrile-styrene) composition and a preparation method thereof. The low-odor, anti-static and anti-bacterial glass fiber reinforced AS composition comprises components in percentage by weight as follows: 39%-88.4% of AS resin, 10%-30% of glass fiber, 1%-10% of a compatilizer, 1%-5% of water master batch, 0.1%-1% of a coupling agent, 10%-15% of an antistatic agent, 0.5%-2% of an anti-bacterial agent and 0.1%-3% of an auxiliary, wherein the water master batch comprises components in percentage by weight as follows: 1%-49% of polypropylene, 50%-98% of water and 0.1%-5% of mineral filler; the compatilizer is PMMA (polymethyl methacrylate); and the coupling agent is a silane coupling agent. The matrix of the composition is AS resin, and the composition has the advantages of good performance, low cost, simple preparation process and the like; and besides, PMMA is taken as the compatilizer, so that bonding force between the glass fiber and the AS resin is strengthened, and the fiber and resin composite material system with the similar performance is enhanced.

Description

technical field [0001] The invention belongs to the field of modified plastics, and in particular relates to a low-odor, antistatic and antibacterial glass fiber reinforced AS composition 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 A...

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
