Low-floating fiber glass fiber reinforced AS (Acrylonitrile Styrene) composition as well as preparation method and application thereof

Abstract

The invention relates to a low-floating fiber glass fiber reinforced AS (Acrylonitrile Styrene) composition as well as a preparation method and application thereof. The low-floating fiber glass fiberreinforced AS composition comprises the following components in percentage by mass: 57.4-88.4% of an acrylonitrile-styrene resin, 10-30% of a glass fiber, 1-10% of an interface modifier, 0.1-0.5% of plant oil and 0.1-3% of aids, wherein the interface modifier is one or more of MABS (Methyl Methacrylate Acrylonitrile Butadiene Styrene), an ASA (Acrylonitrile Styrene Acrylate Copolymer) or EMMA (Ethylene Methyl Methacrylate). With the combination of the interface modifier, the plant oil, the glass fiber, the AS resin and other components, the glass fiber reinforced AS composition is good in processing property, size stability and mechanical property, and in addition a product prepared from the AS composition as a raw material is remarkably improved in fiber floating phenomenon and can be widely applied to the field of household electric appliances.

Description

technical field [0001] The invention relates to the field of modified plastics, in particular to a low-floating-fiber glass fiber-reinforced AS composition and a preparation method and application thereof. Background technique [0002] Acrylonitrile-styrene (AS) resin is a thermoplastic made by copolymerizing two monomers of styrene (ST) and acrylonitrile (AN). AS resin has excellent properties, excellent dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, and good molding and mechanical processing properties. It is an important engineering plastic. Adding glass fiber to AS resin can enhance the strength and thermal deformation resistance of AS resin, and can also reduce the thermal expansion coefficient of AS resin. [0003] Klumperman et al. (W091 / 15543) used styrene-maleic anhydride copolymer (SMA), ABS, AS and glass fiber as raw materials to prepare ABS composites by blending. The composite increases the Vicat softening tempe...

Problems solved by technology

In addition, glass fiber reinforced composite materials are prone to floating fiber problems on the surface of the product, which affects the appearance of the product

Although the floating fibers on the surface of composite materials can be treated with treatment liquid, the treatment process is cumbersome, the composition of the treatment liquid is complex, and the process control requirements are high.
