Paint additive and preparation method thereof

Abstract

The invention discloses a coating additive and a preparation method thereof. The coating additive comprises the following components: paste-like attapulgite clay, nano-titanium dioxide, nano-calcium carbonate, white carbon black, shale diatomite, clove, mint, mint Rosemary, mugwort, hibiscus, licorice, grapefruit peel. The preparation method comprises: firstly preparing paste-like attapulgite clay; weighing Chinese herbal medicine components, pulverizing and mixing to obtain mixture a1; weighing paste-like attapulgite clay and placing it in a reaction vessel, adding mixture a1, stirring and reacting for 1-2 hours, and ultrasonically To obtain mixture a2; weigh nano-titanium dioxide, nano-calcium carbonate, white carbon black, and shale diatomaceous earth, grind them in a ball mill for 0.5-1.5 hours, add mixture a2 and continue grinding for 0.5-1 hour, and then dry. The additive in the invention can make the coating have good waterproof performance, adsorption performance, anti-mildew and bactericidal performance and other multi-functionality, and also has uniform coating and good mechanical strength, and has good application value.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a coating additive and a preparation method. Background technique [0002] At present, coatings have been involved in various fields and are closely related to people's lives. Coating refers to a type of film material that is applied on the surface of an object to form protection, decoration and other special functions. It mainly includes film-forming base materials, pigments, fillers, solvents, and additives. Coatings can be divided into water-based coatings and organic solvent-based coatings according to the solvent, and coatings can be divided into organic coatings and inorganic coatings according to the film-forming base material. [0003] With the development of society and the improvement of living standards, the global environment is deteriorating day by day, and people's awareness of environmental protection and health is gradually increasing, and the requirements for t...

AI Technical Summary

Problems solved by technology

In people's living environment, the use of coatings is essential, and the performance of coatings plays a vital role in the living environment. Therefore, people's requirements for coatings are getting higher and higher, especially in the hope of obtaining functions with multiple properties. Sexual coatings, the existing coatings, the function is relatively single

Indoor air is usually purified in daily life. Common purification methods usually use purifiers, humidifiers and other equipment, or plant indoor plants, or use coatings with specific functions. Most of them are chemical components, which are highly toxic and affect people’s health. Easy to pollute the environment

[0004] At present, there are many kinds of architectural coatings sold in the current market in our country, but with the continuous development of science and technology, people have put forward higher requirements for building materials. In the fields of energy saving, environmental protection, fire prevention, heat preservation, etc., it is impossible to fully meet various needs.

Most of the interior and exterior wall architectural coatings generally do not have environmental protection and other functions. Therefore, architectural coatings and their additives with environmental protection functions are one of the technical issues that are urgently needed to be improved in the construction industry.
