Example Embodiment

[0020] Example 1

[0021] This specific embodiment is a formulation of a nano matte additive with high matting properties and low VOC. The raw materials of the additive include: 1 part of vinyl triethoxysilane, 100 parts of nano alumina, 1 part of citric acid, and 100 parts of deionized water. .

[0022] The above formula is processed, and the processing steps are: add nano alumina and vinyl triethoxy silane to deionized water according to the raw material ratio, and stir evenly at 1000 RPM for pre-dispersion, and then use The nano sand mill grinds it to the nano-primary particle size, then adds citric acid to it to adjust the pH value to 6-7, and reacts at 1000RPM for 0.5 hours to obtain a high matte low VOC nano matte Additive sample 1.

Example Embodiment

[0023] Example 2

[0024] This specific embodiment is a formulation of a nano matte additive with high matting properties and low VOC. The raw materials of the additive include: 10 parts of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane, nano-nitriding 80 parts of aluminum, 5 parts of acetic acid, and 70 parts of deionized water.

[0025] The above formula is processed, and the processing steps are as follows: add nano aluminum nitride and 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane to deionized water according to the ratio of raw materials, and Stir uniformly at a rotation speed of 800RPM for pre-dispersion, then grind it to a nanometer primary particle size with a nano sand mill, then add acetic acid to it to adjust its pH to 6-7, and react at a rotation speed of 800RPM After 3 hours, sample 2 of nano matt additive with high matt property and low VOC was obtained.

Example Embodiment

[0026] Example 3

[0027] This specific embodiment is a formulation of a nano matte additive with high matting properties and low VOC. The raw materials of the additive include: 20 parts of bis(acetylacetonyl) ethoxy isopropoxy titanate, 50 parts of nano silica, 10 parts of oxalic acid, 50 parts of deionized water.

[0028] The above formula is processed, and the processing steps are as follows: add nano silica and bis(acetylacetonyl) ethoxy isopropoxy titanate to deionized water according to the ratio of raw materials, and rotate at 500 RPM Stir uniformly for pre-dispersion, and then grind it to a nanometer primary particle size with a nano sand mill, then add oxalic acid to adjust its pH to 6-7, and react at 500 RPM for 6 hours. Sample 3 of nano matte additives with high extinction and low VOC was obtained.

Abstract

The invention discloses a high-extinction low-VOC (volatile organic compound) nano matte assistant and a preparation method thereof, and the assistant is used for solving the problems that the existing matte paint film is poor in film transparency, and the coating flatness of an original paint liquid can be influenced, so that the paint film surface is rough, and poor in scratch resistance and mark brightening the like; the assistant comprises the following raw materials in parts by mass: 1-20 parts of a nano-modifier, 50-100 parts of nano-powder, 1-10 parts of a pH regulator and 50-100 partsof deionized water. The assistant is added into cathode electrophoretic resin to prepare matte paint, so that the film transparency of the matte paint can be improved, the extinction property is strong, the coating flatness of the original paint liquid cannot be influenced at the same time, and the hardness, fullness and the like of the paint film are improved.

Description

technical field [0001] The invention relates to the field of nano matting additives, in particular to a nano matting additive with high matting property and low VOC and a preparation method thereof. Background technique [0002] At present, with the improvement of people's living standards, everyone's requirements for life are getting higher and higher, and the external senses of things are also more and more fashionable. They are no longer limited to the level of simple usability. This change in aesthetic understanding, Take the surface decoration with matte touch as an example. This kind of emerging surface decoration products are becoming more and more popular among consumers. Nowadays, the matte resins that appear on the market are mainly made by adding matte additives, such as resins such as matte powder and micronized wax, but the matte coatings produced in this way have rough coating films, poor transparency, and are prone to scratches and bright spots. Marks, paint ...
