Low-odor antistatic antibacterial glass fiber reinforced AS (acrylonitrile-styrene) composition and preparation method thereof

Abstract

The invention provides a low-odor antistatic antibacterial glass fiber reinforced AS (acrylonitrile-styrene) composition and a preparation method thereof. The low-odor antistatic antibacterial glass fiber reinforced AS composition comprises the following components in percentage by weight: 39 to 88.4 percent of AS resin, 10 to 30 percent of glass fibers, 1 to 10 percent of a compatilizer, 1 to 5 percent of a hydrophilic master batch , 0.1 to 1 percent of a coupling agent, 10 to 15 percent of an antistatic agent, 0.5 to 2 percent of an antibacterial agent and 0.1 to 3 percent of an additive, wherein the hydrophilic master batch comprises the following components in percentage by weight: 1 percent to 49 percent of polypropylene, 50 percent to 98 percent of water and 0.1 to 5 percent of mineral filler; the compatilizer is PMMA (polymethyl methacrylate); the coupling agent is a silane coupling agent. The low-odor antistatic antibacterial glass fiber reinforced AS composition uses the AS resin as a matrix and has the advantages of excellent performance, low cost, simple preparation process and the like; the PMMA is used as the compatilizer, so that the low-odor antistatic antibacterial glass fiber reinforced AS composition not only is limited to reinforcement on a bonding force between the glass fibers and the AS resin, but also is suitable for reinforcing a composite material system of fibers and resin similar properties.

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 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
