Problems solved by technology

[0004] One of the sources of odor in automobile interiors is the paint sprayed on ABS resin. However, traditional water-based aluminum powder paints often have a strong odor during use, and there will still be odor residues after drying, which has a great impact on users. , it is very promising to develop a water-based interior paint with low odor and good adhesion, hardness, hiding power, appearance and scratch resistance on ABS parts

preparation example Construction

[0048] The preparation method of water-based two-component automotive interior paint, comprises the steps:

[0049] Step 1, take each component by weight, set aside;

[0050] Step 2. Mix and stir the resin, dispersant, half of the co-solvent, deionized water and titanium dioxide evenly, add zirconium beads, and grind for 1.5-2 hours;

[0051] Step 3. While stirring the white slurry obtained in step 2, add leveling agent, substrate wetting agent, defoamer, half of the co-solvent, and part of deionized water, and stir evenly;

[0052] Step 4, add matting powder to the mixed solution obtained in step 3 while stirring, and increase the stirring speed, and stir evenly;

[0053] Step 5, add the thickener while stirring, and adjust the pH value between 7.5-8.5 with a pH regulator.

Embodiment 1

[0056] Step 1. Weigh each component according to the following parts by weight and set aside: 1.5 parts of dispersant; 25 parts of cosolvent; 30 parts of titanium dioxide; 20 parts of resin; 0.3 parts of defoamer; 0.5 parts of leveling agent; 0.5 parts of agent; 2 parts of thickener; 3 parts of matting powder; 0.5 parts of pH regulator; 3 parts of deionized water;

[0057] Step 2. Mix and stir the resin, dispersant, 12.5 parts of co-solvent, deionized water and titanium dioxide evenly, add zirconium beads, grind for 1.5 hours until the fineness is less than 10 microns, and produce slurry;

[0058] Step 3. While stirring the white paste obtained in step 2, add leveling agent, substrate wetting agent, defoamer, 12.5 parts of co-solvent, and deionized water at a low speed of 500-800 rpm Stir evenly under shear force;

[0059] Step 4. Add matting powder to the mixture obtained in step 3 while stirring, and increase the stirring speed, disperse until the fineness is less than 20 m...

Embodiment 2

[0062] Step 1. Weigh each component according to the following parts by weight and set aside: 2.5 parts of dispersant; 30 parts of cosolvent; 40 parts of titanium dioxide; 30 parts of resin; 1 part of defoamer; 1 part of leveling agent; substrate wetting 1 part of agent; 5 parts of thickener; 6 parts of matting powder; 1 part of pH regulator; 6 parts of deionized water;

[0063] Step 2. Mix and stir the resin, dispersant, half of the co-solvent, deionized water and titanium dioxide evenly, add zirconium beads, grind for 2 hours until the fineness is less than 10 microns, and produce slurry;

[0064] Step 3. While stirring the white paste obtained in step 2, add leveling agent, base material wetting agent, defoamer, half of the co-solvent, and part of deionized water, at a low speed of 500-800 rpm Stir evenly under shear force;

[0065] Step 4. Add matting powder to the mixture obtained in step 3 while stirring, and increase the stirring speed, disperse until the fineness is l...

Abstract

The invention discloses waterborne two-component automotive interior paint. The waterborne two-component automotive interior paint is characterized by being prepared from the following components in parts by weight: 1.5 to 2.5 parts of dispersant, 25 to 30 parts of cosolvent, 30 to 40 parts of titanium dioxide, 20 to 30 parts of resin; 0.3 to 1 part of defoamer; 0.5 to 1 part of flatting agent; 0.5 to 1 part of substrate wetting agent; 2 to 5 parts of thickener; 3 to 6 parts of extinction powder; 0.5 to 1 part of pH regulator; and 3 to 6 parts of deionized water. Compared with other waterborneinterior paints on the market, the waterborne two-component automotive interior paint has slight odor after opening, no odorless residue after drying, is easy to construct and free from benzene, heavy metals and high content of VOC and other poisonous and harmful substances, can significantly improve an odor problem of the waterborne interior paint, provides excellent construction performance, and has greater market demands and broader prospects.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based two-component automotive interior paint and a preparation method thereof. Background technique [0002] Because ABS resin has the characteristics of impact resistance, low temperature resistance, chemical resistance and electrical properties, as well as easy processing, stable product size, and good surface gloss, thermoplastic ABS resin is widely recognized as a kind that can be freely designed. Engineering materials with outstanding aesthetics, flow, toughness, dimensional stability and high heat resistance, so they have been playing an important role in the production of automotive components. [0003] The important goal pursued by ABS resin for automotive interiors is to reduce the volatility of toxic and odorous gases in the material and improve the air quality inside the car. Therefore, low-odor materials are one of the common goals pursued by car manufacture...
