AI Technical Summary

Problems solved by technology

[0004] 1. The validity period is short, which is not conducive to long-term storage and use
In the process of use, it is found that the main components of the existing coatings are prone to aggregation as the storage time continues to prolong, which makes the overall performance of the coatings decline, so that the target spraying effect cannot be achieved
[0005] 2. The existing coatings form a film, which requires oil and resin to wrap the functional components, and this method affects the functionality of the main components after actual spraying
[0006] 3. Existing coatings often have a single function and generally only have an antibacterial effect, and this single-performance coating often cannot meet the needs of modern production and life
In addition, and even the most common antibacterial function, often due to its small radiation surface, the antibacterial effect is not obvious

Abstract

The invention provides a multifunctional antibacterial coating. The multifunctional antibacterial coating is prepared from a material A and a material B. The coating is long in storage life, broader in functionality, better in antibacterial and bacteriostatic effect, can realize multiple effects of resisting bacteria, purifying air, removing odor and the like after drying and curing, can also emit far infrared rays beneficial to the human body under the heating condition, stimulate energy of the human body and promote physical health, can be sprayed to surfaces of various carriers and is widely applied to various industries.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a multifunctional antibacterial coating and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the continuous development of modern industry, environmental problems are becoming increasingly severe. Traditional coatings often add some harmful ingredients due to the craftsmanship, and are easy to pollute the environment, which is not good for human health, and is being phased out. From the perspective of environmental protection and human health, the development of coatings with functional effects such as antibacterial can not only improve the safety of coatings, protect human health, but also meet environmental protection requirements. [0003] In the production of existing environmentally friendly functional coatings, most of the functional coatings have the following problems due to the influence of the spraying process: [0...
