Embodiment 1

[0019] a. Weigh 42.0% deionized water, 5.5% wetting and dispersing agent (Wenkel HLD-8 / KS), 6.0% wetting and dispersing agent (sunrise TG), 6.0% brightener ( Put Wenkel E-360), 10.0% ethylene glycol, 0.5% ammonia water and 0.2% Proxel BZ plus in the dispersion tank, stir and disperse at a speed of 450rpm for 12min to obtain a uniform transparent solution;

[0020] b. Add 35.0% Pigment Red 122 (Jinyuan Pigment Red 1221D) into the homogeneous transparent solution obtained in step a during the dispersion and stirring process, disperse at a speed of 1800 rpm, and disperse for 45 minutes to obtain an environmentally friendly organic pigment pre-dispersed color paste ;

[0021] c. Grind the pre-dispersed environment-friendly organic pigment color paste obtained in step b. The method used for grinding is horizontal grinding, and the grinding medium is high-purity zirconium beads of 0.6 to 0.8 mm. When the average particle size of the color paste is D 80 <0.5μm, when the particle siz...

Abstract

The invention discloses a preparation method of high-gloss environment-friendly organic pigment slurry for natural latex balloons. The high-gloss environment-friendly organic pigment slurry comprises organic pigment, wetting dispersant, brightener, humectant, anti-mildew bactericide, pH regulator and deionized water. The preparation method includes: pre-dispersing and grinding the components, and then performing quality inspection, vacuum defoaming and filtration to obtain the required environment-friendly organic pigment slurry. The high-gloss environment-friendly organic pigment slurry prepared by the method has the advantages that the slurry is high in glossiness and good in environment protection performance, the deionized water is used as the solvent, and the slurry conforms to the environment-friendly requirement of China.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to the field of natural latex in the rubber industry. Background technique [0002] With the development of the latex products industry, especially the continuous development of the natural latex balloon industry, the use of pigments and ordinary colorants to color natural latex balloons has been unable to meet environmental protection and application requirements. The use of pigments for coloring has the problems of dust pollution and high toxicity. Ordinary colorants contain unhealthy and environmentally unfriendly factors such as alkylphenol polyoxyethylene ether (APEO), azo compounds (AZO), heavy metals, and volatile organic components (VOC), which affect the environmental protection of natural latex balloon coloring. Great security risk. American toy safety standard ASTMF963, European Union toy safety standard EN71, REACH regulations and "National Toy Safety Technical Specificat...
