Abstract

The invention provides low-odor high-adsorption black color master batch and a preparation process thereof, which can effectively solve the problem that the black color master batch for the existing car is severe in odor. The low-odor high-adsorption black color master batch is prepared from the following raw materials in parts by weight: 40 to 45 parts of carbon black BP713, 40 to 51 parts of linear low-density polyethylene LLDPE-M500026, 2 to 10 parts of polyethylene wax AC-6A and 0.5 to 2 parts of antioxidant AO-50. The preparation process successively comprises the following steps: stirring, mixing, granulating, dehydrating, and packaging, wherein the mixing process, 5 parts of odor adsorbent is injected into a mixing chamber of a continuous dual-screw mixer, the odor adsorbent is a mixed solution formed by blending water and porous odor adsorbent, the odor adsorbent in the mixing chamber is heated and evaporated into vapor, the vapor dilutes and adsorbs an odor substance generatedby virtue of high-temperature dissociation in the mixing process, and the vapor is completely discharged out of the mixing chamber by virtue of a smoke discharging gate arranged on a mixing section.

Description

technical field [0001] The invention relates to the field of production and preparation of color masterbatches, in particular to a low-odor and high-adsorption black color masterbatch and a preparation process thereof. Background technique [0002] Masterbatch is a new type of special colorant for polymer materials. It usually consists of three basic elements: pigment, carrier and additives, and is used for the dyeing of plastic products. [0003] Black masterbatch is the most commonly used color masterbatch in plastic processing. It is a plastic colorant that is well dispersed with a high proportion of pigments or additives and thermoplastic resins. The selected resin has good lubricity to the colorant. Wet and disperse, and have good compatibility with the material to be colored. It is widely used in plastic processing industries such as injection molding, extrusion molding and blow molding. [0004] Plastic modification is to improve or increase the functions of large q...
