Abstract

The invention discloses color paste for environment-friendly latex and a preparation method of the color paste. The color paste for the environment-friendly latex is prepared from the following raw materials in parts by weight: 38-50 parts of modified titanium dioxide, 6-10 parts of a wetting dispersant, 0.5-1 part of an anti-settling agent, 0.1-0.6 part of a defoaming agent, 0.1-0.5 part of a pH regulator and 40-55 parts of deionized water. The color paste for the environment-friendly latex has good stability, dispersing performance and coloring strength, titanium dioxide is modified, firstly, the alkali resistance of the titanium dioxide is remarkably improved, so that the titanium dioxide can be well applied to a latex formula system, secondly, tests verify that the potential of modified ZETA is increased. The mutual repulsive interaction among titanium dioxide particles is strong, the acting force of agglomeration and flocculation, stability and coloring strength can be resisted, and the titanium dioxide can be well dispersed in water.

Description

technical field [0001] The invention relates to the technical field of color paste, in particular to a color paste for environment-friendly latex and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, a large number of latex products appear in people's daily production. Latex flows out from rubber tree tapping and is milky white. It is a natural and important industrial raw material. Latex is used in labor protection products (such as latex) Gloves), balloons are widely used in the field. [0003] As a white pigment commonly used in the production of latex products, titanium dioxide is usually added to the medium used in a highly dispersed state, and its dispersion, gloss, and weather resistance in latex all have an important impact. The dispersion effect of commonly used titanium dioxide is not ideal when applied to water-based systems, which directly affects the storage stabilit...
