Abstract

The invention provides a preparation method of a large biological water-based paint. The preparation method comprises the following steps: preparing a cyclodextrin solution containing a plant extract, preparing a cellulose mixture, and preparing the water-based paint. According to the large biological water-based paint prepared by the invention, plant active ingredients are added, so that the large biological water-based paint has good antibacterial activity, and the inhibition rate on staphylococcus aureus is 95.7-96.2%, the inhibition rate on escherichia coli is 96.2-96.9%, the inhibition rate on pseudomonas aeruginosa is 92.5-93.1%, and the inhibition rate on candida albicans is 92.9-94.3%; the paint has high wear resistance, and the hardness can reach 2H when the paint is sprayed on a steel plate; and when the paint is sprayed on a steel plate, the impact resistance of the paint is 73-76cm.

Description

technical field [0001] The invention designs a method for preparing a large biological water-based paint, which belongs to the technical field of paint materials. Background technique [0002] Due to its strong hardness, high fullness of paint film, and tolerant construction, paint is the first choice of paint for many people's decoration. With the pressure of environmental protection policies, consumers' awareness of environmental protection is constantly improving. In particular, provinces and cities across the country have introduced VOC emission limit standards to encourage the use of non-solvent-based coatings, which has brought opportunities for the development of water-based paints and other environmentally friendly coatings. Although traditional coatings still occupy a relatively large market share, water-based paints are a green industry and the future development direction of paints. Domestic leading water-based paint companies are on the rise. [0003] It is an i...
