[0025] The preparation method of described modified polyvinyl alcohol is:

[0026] ①Heat the deionized water to boiling, then add zinc borate, epoxy resin, and rosin in sequence, and stir at 65r / min for 10 minutes;

[0027] ②Add polyvinyl alcohol to ①, adjust the temperature to 72°C, and stir at 120r / min for 10 minutes;

[0028] ③Add ethylene carbonate to ②, adjust the temperature to 28°C, stir at a speed of 180r / min under a pressure of 1.024MPa for 1 hour, then cool naturally to room temperature;

[0029] The hemp fiber and nano-alumina are blended: after mixing the hemp fiber and nano-alumina evenly, add it to a stearic acid solution with a mass concentration of 3.52%, heat it to 38°C, and heat it at a speed of 100r / min. After stirring for 15 minutes, adjust the temperature to 68°C, stir at a speed of 120r / min for 15 minutes, cool to room temperature naturally, stir at room temperature for 30 minutes at a speed of 90r / min, filter, and dry;

[0030] The reactive diluent is ...

Abstract

The invention discloses green and environment-friendly antibacterial paint which is prepared from the following components: butyl acrylate, polyethylene glycol, methyl methacrylate, a composite emulsifier, nano aluminum oxide, modified methacrylic acid, sodium aluminosilicate, hemp fibers, dimethyl phthalate, modified polyvinyl alcohol, an active diluting agent, a de-foaming agent and de-ionized water. The paint disclosed by the invention is green and has no pollution; the hardness of common aqueous acrylate paint can be reduced; the solvent-resisting performance is improved, and the thermal bonding and cold brittleness is reduced; the paint has high surface strength, good corrosion resistance, excellent anti-pollution performance, good adhesion and lubricating performance, high rigidity, high curing speed, low cost, good attaching performance and excellent solvent-resisting performance; and the performances are mainly obtained through a reasonable formula and an accurate preparation process in the invention. Under the same utilization condition, the service life of a coating formed by the paint is 72% longer than that of a coating formed by the common aqueous acrylate paint.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a green and environment-friendly antibacterial paint. Background technique [0002] With the daily increase in the price of chemical raw materials, the price of solvent-based coatings has become the key to restricting its wide application. Compared with solvent-based coatings, water-based coatings have received more and more attention from researchers because of their greatly reduced use of organic solvents. However, in the process of making water-based paints, there are often problems such as the raw materials are not easy to dissolve, the hardness is low, the drying is slow, and the paint gloss is not good. Contents of the invention [0003] The object of the invention is to provide a kind of green environmental protection antibacterial coating, realize through the following technical proposals: [0004] A green environment-friendly antibacterial coating, made of the follow...
