Abstract

The invention provides an antistatic master batch which comprises the following raw materials in percentage by weight: 40-97% of polymer resin, 1-49% of black talcum powder, 1-49% of a carbon-based antistatic material and 1-10% of other auxiliaries, and the total proportion of the black talcum powder and carbon black does not exceed 50%. The black talcum powder is added into the raw materials of the master batch, so that no pungent smell is emitted when the master batch is used; when applied to the processing industries of injection molding products and the like, the antistatic master batch overcomes static electricity generated by friction of the high polymer material, effectively improves the chromatic aberration problem of the product caused by static electricity, enables the product quality to be stable, and enables the product to have a certain anti-static effect, and also has a good effect on surface dust prevention of the product.

Description

technical field [0001] The invention belongs to the field of color masterbatches, and in particular relates to an antistatic masterbatch and a preparation method thereof. Background technique [0002] Masterbatch is a high-concentration pigment mixture, mainly composed of pigments, carrier resins and additives. Its main feature is to mix ultra-high concentration pigments with carrier resin. In actual production, only a small amount of color masterbatch Mixing with uncolored resin raw materials can make the product color meet the design requirements. The main components of the color masterbatch in the prior art are carrier resin, pigment and dispersant. Although the dispersibility of the color masterbatch is very good, the functionality of the color masterbatch is relatively single. In the environment, the use of color masterbatch is subject to certain restrictions. Contents of the invention [0003] The object of the present invention is to provide an antistatic masterba...
