Example Embodiment

[0015] The preparation method of the AS plastic of the present application is now described, so as to facilitate those skilled in the art to understand the prepared glass fiber reinforced recycled AS plastic. That is, a method for preparing glass fiber reinforced recycled AS plastic includes the following steps:

[0016] S1. Drying the recycled material AS in advance, wherein the drying temperature of the recycled material AS is 85~105℃ and the drying time is 3~5H;

[0017] S2. After the drying treatment is completed, weigh 65~90 parts of recycled material AS by weight and add it to the high-speed mixer. At the same time, weigh out 0.5~2.5 parts of compatibilizer and 0.3~0.5 parts of coupling agent by weight. Add 0.3~0.5 parts of antioxidant and 0.3~0.5 parts to the high-speed mixer, and then carry out the mixing treatment through the high-speed mixer for 10-20 minutes to obtain a uniformly mixed mixture;

[0018] S3. Add the uniformly mixed mixture to the twin-screw extruder, and a...

Abstract

The invention provides a glass fiber reinforced regenerated AS plastic. The glass fiber reinforced regenerated AS plastic comprises the following raw materials in parts by weight: 65-90 parts of a reclaimed material AS, 0.5-2.5 parts of a compatilizer, 0.3-0.5 part of a coupling agent, 0.3-0.5 part of an antioxidant and 10-35 parts of glass fibers, wherein the compatilizer is styrene (methyl) acrylic oligomer. The glass fiber reinforced regenerated AS plastic has the advantages of high heat resistance temperature, low shrinkage rate, good mechanical property and the like.

Description

technical field [0001] The invention relates to the technical field of modified plastics, in particular to a glass fiber reinforced recycled AS plastic and a preparation method thereof. Background technique [0002] During the production and use of AS resin (styrene-acrylonitrile copolymer), a large amount of waste or defective materials and recycled products will be produced; secondly, the existing recycled AS plastics have disadvantages such as high melt viscosity and high water absorption rate. Usually, waste materials, defective materials or recycled products will be recycled and granulated for modification. For example, adding glass fiber to recycled AS plastics can enhance its strength and thermal deformation resistance, so that glass fiber reinforced recycled AS plastics can be used Widely used in high-speed air conditioner fan blades in a wide temperature range. However, conventional recycling granulation fails to make full use of the economic value of these recycle...
