Problems solved by technology

With the improvement of environmental protection requirements, the previous solvent-based color pastes are gradually changing to water-based color pastes. During the use of color pastes, enterprises often face problems such as low grinding efficiency, slow micronization process, easy sedimentation, and difficulty in long-term storage. The problem is that the current color paste has insufficient environmental protection and water compatibility. Therefore, we propose a water-soluble environmentally friendly nano color paste and its preparation method

Abstract

The invention discloses water-soluble environment-friendly nanometer color paste and a preparation method thereof and belongs to the technical field of color paste preparation. The water-soluble environment-friendly nanometer color paste is characterized by being prepared from the following components in parts by weight: 10 to 20 parts of dispersing agent, 10 to 30 parts of nanometer pigment, 5 to10 parts of surface active agent, 0.2 to 0.5 part of defoaming agent, 18 to 28 parts of wetting agent, 0.2 to 0.4 part of corrosion remover, 4 to 10 parts of humectant, and 15 to 30 parts of deionized water. The preparation method comprises the steps of adding 60 percent of dispersing agent, defoaming agent, corrosion remover and wetting agent and 70 percent of deionized water into a reactor; stirring at the speed of 100 to 200rpm for 15 to 20 minutes in an opening type sand mill, and then increasing by five times of stirring rate; adding 40 percent of surface active agent, nanometer pigmentand humectant into the reactor, continuously stirring for 25 to 30 minutes to obtain a mixed color paste, and coarse grinding and dispersed grinding the mixed color paste. The water-soluble nanometercolor paste prepared by the preparation method provided by the invention is small in particle size, narrow in distribution, good in stability, environmentally friendly and safe.

Description

technical field [0001] The invention relates to the technical field of color paste preparation, in particular to a water-soluble environment-friendly nano color paste and a preparation method thereof. Background technique [0002] my country's annual pigment output exceeds 2.6 million tons, 40% of which are made into color pastes, and the annual use of color pastes exceeds 1.4625 million tons. With the improvement of environmental protection requirements, the previous solvent-based color pastes are gradually changing to water-based color pastes. During the use of color pastes, enterprises often face problems such as low grinding efficiency, slow micronization process, easy sedimentation, and difficulty in long-term storage. The problem is that the current color paste is not environmentally friendly and has insufficient water compatibility. Therefore, we propose a water-soluble environmentally friendly nano color paste and its preparation method. Contents of the invention ...
