Embodiment 1

[0021] A preparation method for antibacterial organic sol coating, comprising the following steps:

[0022] (1) Take 0.4 parts by weight of octylisothiazolinone, add it to acetone 64 times its weight, and stir evenly to obtain a bacteriostatic dispersion;

[0023] (2) Take 3 parts by weight of the initiator, add it to acetone 10 times its weight, and stir evenly to obtain the initiator solution;

[0024] (3) Take 1 part by weight of polyacrylamide, add it to deionized water 30 times its weight, and keep stirring at 70°C for 6 minutes to obtain an amide solution;

[0025] (4) Take 50 parts by weight of maleic anhydride, add it to the above antibacterial dispersion, stir evenly, send it into the reaction kettle, feed nitrogen, adjust the temperature of the reaction kettle to 60°C, add the above initiator solution dropwise, After the dropwise addition, keep warm and stir for 2 hours, discharge, mix with 4 parts by weight of tetramethyldisiloxane, and stir to normal temperature t...

Embodiment 2

[0034] (1) Take 1 part by weight of octylisothiazolinone, add it to acetone 70 times its weight, and stir evenly to obtain a bacteriostatic dispersion;

[0035] (2) Take 4 parts by weight of the initiator, add it into acetone with 16 times its weight, and stir evenly to obtain the initiator solution;

[0036] (3) Take 2 parts by weight of polyacrylamide, add it to 40 times its weight in deionized water, and keep stirring at 75°C for 10 minutes to obtain an amide solution;

Abstract

The invention discloses a bacteriostatic organosol paint preparation method. By effectively dispersing the bacteriostatic sol in epoxy resin, the film stability intensity is increased, dispersion uniformity of the effective bacteriostatic components in a film can be guaranteed, according to the invention, octylisothiazolinone, calcium propionate and sodium diacetate are added for effectively increasing the bacteriostasis performance of a finished product emulsion, and the sol prepared by taking tetraethoxysilane as a precursor can effectively increase the stability of the finished product emulsion.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a preparation method of an antibacterial organic sol coating. Background technique [0002] Epoxy resins are used in anti-corrosion coatings with liquid resins accounting for the largest share, but most of the coatings used in industry are solvent-based coatings. Conventional solvent-based coatings mostly use aromatic hydrocarbons, esters, alcohols, ketones, etc. as solvents , these solvents have varying degrees of toxicity, and the volatiles are directly discharged into the air, causing serious environmental pollution. With the enhancement of people's awareness of environmental protection, new anti-corrosion coatings that do not contain organic solvents or low VOC such as powder coatings, solvent-free Green coatings such as coatings and water-based coatings have been developed one after another. Powder coatings have been restricted in their development due to their harsh curi...
