Colour master batch with low combustion speed

Abstract

The invention relates to a colour master batch with a low combustion speed. The colour master batch is composed of the following components in percentage by weight: 20-70% of styrene copolymer, 0.01-70% of toner, 1-20% of dispersant, 0-50% of synergist and 0-40% of filler, wherein the toner is one or more of inorganic pigments, organic pigments or dyes, and the temperature resistances of the inorganic pigments, organic pigments or dyes are not less than 200 DEG C. When the colour master batch provided by the invention is applied to the colouring of ABS products, the combustion speeds of the ABS products achieve the standards of UL94 HB, and the ABS products are excellent in dispersibility and free from colour dots and colour lines; master batches with different colours can be prepared as needed; and meanwhile, the colour master batch has a low influence on the mechanical properties of the products.

Description

technical field

[0001] The invention relates to the field of plastic coloring, in particular to a color masterbatch with a low burning rate. Background technique

[0002] ABS resin is a thermoplastic composed of three components: acrylonitrile, styrene and butadiene. It is a two-phase structure polymer material in which the polybutadiene rubber phase is dispersed in the continuous phase of AS resin. ABS resin not only has excellent mechanical properties of toughness, hardness, and rigid phase balance, but also has good chemical resistance, dimensional stability, surface gloss, low temperature resistance, coloring performance, and processing fluidity. As one of the five general-purpose engineering plastics with the largest output and widest application, it is widely used in many fields such as automobiles, appliances, electronic devices, household appliances, and construction.

[0003] With the strengthening of people's safety awareness, the requirements for the combustion ...
