Abstract

The invention provides a low-odor, low-temperature-resistant, flame-retardant ABS composition and a preparation method thereof. The composition is prepared from the following raw materials in parts by weight: 47-69 parts of ABS, 5-10 parts of phosphorus-based flame retardant, 15-20 parts of carbon agent A, 10-20 parts of carbon-forming agent B, and 1-3 parts of physical adsorbent. The low-odor, low-temperature-resistant and flame-retardant ABS composition of the present invention improves the char-forming rate of the material during the combustion process by adding the char-forming agent A and the char-forming agent B, and synergizes with the phosphate ester flame retardant to form a new type of Flame retardant system, the material has good flame retardant performance, and a small amount of phosphate ester flame retardant is added to achieve V-0 flame retardant grade.

Description

technical field [0001] The invention belongs to the field of modified plastics, in particular to a low-odor, low-temperature-resistant, flame-retardant ABS composition and a preparation method thereof. Background technique [0002] ABS material has the advantages of high gloss, high rigidity and impact resistance, and is widely used in household appliances, lighting, office, automobile and other industries. Due to the low char formation rate of ABS resin materials, the flame retardants used in V-0 flame retardant ABS on the market are generally brominated flame retardants. During the reprocessing process of brominated flame retardant ABS and the injection molding process, small molecules such as bromide, ABS residual monomer, and ABS synthesis solvent will be volatilized when the material is heated, resulting in a great odor. The smell of the scene will be very strong, and the experience of the working environment will be low. In addition, one type of application of ABS ma...
