Abstract

The invention relates to the technical field of fire-retardant resins, and discloses an acrylonitrile-butadiene-styrene (ABS) resin and a preparation method thereof. The resin is prepared from the following components in parts by weight: 1000 parts of ABS resin, 150-350 parts of halogen flame retardants, 30-70 parts of synergistic fire retardant, 30-70 parts of smoke suppressant, 1-10 parts of antioxidant, and 1-10 parts of lubricant. The preparation method comprises the following steps: fully and evenly mixing the 1000 parts of ABS resin, 150-350 parts of halogen flame retardants, 30-70 parts of synergistic fire retardant, 30-70 parts of smoke suppressant, 1-10 parts of antioxidant and 1-10 parts of lubricant; feeding the materials to a double-screw extruder through a precise metering feeder after completely mixing; fully fusing the materials under the conditions of shearing, mixing and conveying of screws; and finally preparing granules after extruding, bracing and cooling. The ABS resin disclosed by the invention is low in smoke generation in combustion, does not generate harmful gases such as dioxin, does not generate molten droplets, accords with the instruction of restriction of hazardous substances (ROHS) of the European Union, and is low in cost and convenient to process.

Description

technical field [0001] The invention relates to the technical field of flame-retardant resins, in particular to an environmentally friendly low-smoke flame-retardant ABS resin and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene terpolymer (ABS) is a common general-purpose resin. ABS has good comprehensive performance, high toughness, easy electroplating and coloring, and is easy to process. It is widely used in automobiles, home appliances, and electronic appliances. , machinery and other industries, and with the development of modern technology, the demand for ABS is also growing rapidly, and the current output ranks fifth in resin output. Although ABS has many advantages, there are still some defects, such as poor flame retardancy, oxygen index is only 18-20, and vertical combustion is only HB level of UL94 standard. Poor flame retardancy restricts the development of ABS, because fires caused by flammable plastics, the expansion...
