Abstract

The invention discloses a mildew-proof and antibacterial coating as well as a preparation method and application thereof. The mildew-proof and antibacterial coating is prepared from the following components: cinnamic aldehyde, citral, eugenol and white vaseline. The preparation method of the mildew-proof and antibacterial coating comprises the following steps: (1) mixing 16-50 parts of cinnamic aldehyde, 17-50 parts of citral and 17-50 parts of eugenol at room temperature, and performing stirring under a sealed condition to obtain mixed liquid; and (2) dropwise adding the mixed liquid to 850-950 parts of white vaseline to be mixed, performing stirring under a sealed condition, and keeping the liquid still until the liquid is not layered so as to obtain the mildew-proof and antibacterial coating. The preparation process of the mildew-proof and antibacterial coating is simple and easy to implement. The mildew-proof and antibacterial coating disclosed by the invention is low in toxicity and can be coated on the surface of plastic and particularly the surfaces of household appliances such as an air conditioner, a refrigerator and a washing machine so as to enable the household appliances to have mildew-proof and antibacterial properties.

Description

technical field [0001] The invention relates to the technical field of mildew-proof coatings, in particular to a mildew-proof and antibacterial coating and its preparation method and application. Background technique [0002] With the advancement of technology and the development of materials, plastics are widely used as a substitute for metals and natural materials in the fields of automobiles, home appliances, small electronic products, and aerospace. The mildew of plastic can reduce the performance and service life of materials. In household appliances such as refrigerators, washing machines, and air conditioners, the mold produced by plastic mold will directly contact with food, clothing, air, etc., and the toxins produced by its metabolism seriously affect people's health. health and quality of life. And because these home appliance plastics are in a humid environment for a long time, it also provides a hotbed for the growth of mold. The mildew phenomenon of the produc...
