Modified composite for bulk polymerization acrylonitrile-butadiene-styrene and preparation method thereof

Abstract

The present invention relates to a bulk polymerized acrylonitrile-butadiene-styrene modified complex. The present invention is characterized in that the complex consists of the raw materials of the following weight percentages: 58.0 to 86.5 percent of acrylonitrile-butadiene-styrene (ABS), 10 to 24 percent of heat-resistant modifier, 0.3 to 1.0 percent of UV absorber, 0.5 to 3 percent of siliconemaster batch, 0.5 to 5 percent of odor inhibitor, 2 to 8 percent of flame retardant, 0.1 to 1 percent of lubricant, and 0.1 to 1 percent of coupling agent. The preparation method is: the raw materialsare weighed according to the weight percentages; the bulk acrylonitrile-butadiene-styrene (ABS) resin, the UV absorber, the odor inhibitor, the silicone master batch, the flame retardant and the processing acid are dried and mixed in the high-speed mixer for 3 to 5 minutes; the mixed raw materials are arranged in the twin-screw machine to melt, extrude and granulate; in the extrusion process, theheat-resistant modifier is added evenly through the measurement of the lateral precise feeding system; the pull strip is extruded, and the mixture is cooled, palletized and dried; then the final produce can be made. The advantage of the present invention is that the product has the smell volatility and the good flame-retardant properties; the produce is suitable for the industry and field of theinterior decorative component of the automobile, the refrigerator, the electronic appliance and so on.

Description

technical field [0001] The present invention relates to a kind of bulk polymerized acrylonitrile-butadiene-styrene modified compound and preparation method thereof, especially to a kind of acrylonitrile-butadiene-styrene ternary copolymerization resin (ABS) produced by bulk method ) modified composite material, specifically involving the preparation of a modified composite material suitable for various fields such as automotive interior parts, refrigerators, and electronic appliances by adding nano-scale flame retardants and odor inhibitors that can effectively suppress unpleasant odors. The utility model relates to a non-volatile body ABS material, which belongs to the technical field of chemical materials. Background technique [0002] Styrene acrylonitrile copolymer, that is, acrylonitrile-butadiene-styrene ABS (acrylnitrile-butadiene-strene copolymer), due to its excellent processing properties, good mechanical properties, and chemical resistance, it is widely used in au...

Problems solved by technology

[0003] However, because acrylonitrile-butadiene-styrene ABS will release some unpleasant odors to varying degrees, especially various automotive interior parts made of acrylonitrile-butadiene-styrene ABS materials, etc. Material products have gradually been questioned by many consumers; and ABS is a flammable material (oxygen index is 18.3-20.0), and it will release a lot of smoke that is easy to suffocate when burned. As people's awareness of environmental protection continues to increase, Acrylonitrile-butadiene-styrene ABS will be more challenged in these aspects, and higher and higher requirements are put forward for acrylonitrile-butadiene-styrene ABS materials. In order to further expand acrylonitrile-butadiene-styrene ABS For the application of diene-styrene ABS materials in related fields, and to improve the cost performance of acrylonitrile-butadiene-styrene ABS, it is necessary to find an effective way to prepare low-odor, even odorless, and excellent barrier properties.
