Abstract

The invention discloses a strong acid corrosion resistant color master batch, the color master batch is prepared from the following raw materials in parts by weight: 50-80 parts of carrier resin, 6-12 parts of a toner, 0.5-1 part of an additive and 0.3-0.5 part of a filler, the carrier resin is a mixture of PC resin and HIPS resin, the toner is titanium dioxide, and the filler is silicon carbide, the invention also discloses a preparation method of the color master batch. The filler adopts silicon carbide to enhance and modify the color master batch and improve the mechanical strength, the toner adopts titanium dioxide to improve the fading resistance of the color master batch, and the resin adopts the combination of PC resin and HIPS resin to improve the impact toughness and surface smoothness of the color master batch. The additive is silicon dioxide, the filler is silicon carbide, and the toner is titanium dioxide, so that the strong acid and strong alkali resistance and corrosion resistance of the color master batch can be improved, and a foaming agent and a plasticizer are combined to weaken secondary valence bonds among resin molecules and increase the mobility of resin molecular bonds, so that the flexibility is enhanced, the color master batch is easy to process, and the stability of the color master batch is improved.

Description

technical field [0001] The invention belongs to the technical field of color masterbatches, in particular to a color masterbatch resistant to strong acid corrosion and a preparation method thereof. Background technique [0002] The full name of color masterbatch is color masterbatch, also called color seed. It is a new type of special colorant for polymer materials, also known as pigment preparation. The color masterbatch is mainly used in plastics. The color masterbatch is composed of pigments or dyes, carriers and additives. Composed of two basic elements, it is an aggregate made by uniformly loading super-constant pigments in the resin. It can be called a pigment concentrate, so its coloring power is higher than that of the pigment itself. It is processed with a small amount of color masterbatch and Colored resins or products that can achieve the designed pigment concentration by mixing uncolored resins. [0003] Color masterbatches are classified by carrier: such as PP ...
