Abstract

The invention relates to a chromotropic paint used for a medical instrument and a preparation method and an application thereof. The chromotropic paint comprises the following raw materials in parts by weight: 25-50 parts of an aqueous hydroxyl acrylic emulsion, 5-20 parts of a curing agent, 2-5 parts of a cosolvent, 1-5 parts of organic silicone powder, 1-5 parts of nano alumina, 0.05-0.5 parts of nano zirconia, 0.1-3 parts of nano negative ion powder, 4-8 parts of titanium dioxide, 0.05-0.5 parts of nano zinc oxide, 1-6 parts of temperature-sensitive color-changing powder, 0.1-1 part of silica sol, 0.1-0.2 parts of a pH conditioning agent, 0.1-0.2 parts of an antifoaming agent, 2-5 parts of a film-forming auxiliary agent, 0.3-0.5 parts of a dispersant, 0.3-0.5 parts of a base material wetting agent, 5-10 parts of deionized water, and 0.5-1.0 parts of a thickening agent. The VOCs content of the paint is low, and a coating has good light resistance, chemically-resistant performance, hardness, bacterinertness, air cleaning performance, and color-changing indication effect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a color-changing coating for medical devices and a preparation method and application thereof. Background technique [0002] With the improvement of living standards, medical devices are used more and more widely, ranging from medical beds in hospitals to toilets in families. Due to the particularity of the application environment of medical equipment and the customers are mainly patients or the infirm, medical equipment has higher and higher environmental protection requirements for coatings. Traditional paints contain a large amount of volatile organic compounds (VOCs). Various volatile organic compounds such as toluene, benzene, and xylene are released. When VOCs in the air reach a certain concentration, it will cause symptoms such as headache, nausea, vomiting, fatigue, etc., and even cause convulsions and coma in severe cases, damage the liver, kidneys, brain and nervous system, and...
