Problems solved by technology

[0002] Due to its wide range of uses, coatings have different performance requirements due to different uses. Some require high adhesion, some require low temperature or high temperature resistance, some require superior electrical insulation, and some require It is required to have good water resistance, some require antibacterial properties, some require better leveling properties, some require less emission of volatile organic substances, etc., and most of the time, coatings are required to have multiple excellent properties at the same time. Rather than a single performance, but most of the coatings currently on the market are still relatively single performance, which requires the development of a new coating that can have multiple excellent properties at the same time

Embodiment 1

[0053] The preparation method of traditional antibacterial photocuring coating:

[0054] ①Sequentially add 51g of water-based polyurethane acrylate, 10g of trimethylolpropane triacrylate diluent, 8g of tripropylene glycol diacrylate diluent and 14g of ethyl acetate solvent, and disperse at 1000r / min for 30min;

[0055] ② Then add 0.5g of acrylic resin leveling agent and 2.5g of photoinitiator, and disperse at 800r / min for 30min;

[0056] ③ Slowly add 2g of nano-silver antibacterial additive at 400r / min, and continue to disperse for 30min;

[0057] ④ Finally, add 12g of butyl acetate solvent to Iwata 2# cup and adjust the viscosity to 20s at 25°C to obtain the traditional antibacterial light-curing coating.

Embodiment 2

[0059] A kind of antibacterial UV paint containing castor oil base, it is prepared by following component distribution ratio and preparation method:

[0060] S1, preparation of castor oil-based UV curing polyurethane acrylate:

[0061] S11. Mix and stir 5.8 mol of polyethylene glycol, 1.5 mol of polyester diol and 1 mol of castor oil evenly and raise the temperature to 115°C, dehydrate under reduced pressure for 2.5 hours and then cool down to 75°C, then add 1 mol of isoflurane respectively Ketone diisocyanate and the bismuth laurate catalyst of 0.002mol, the drop rate is controlled to be dropped within 1.5h, and the reaction is 3h to obtain the mixed solution M;

Abstract

The invention discloses a castor oil base containing antibacterial UV coating. The castor oil base containing antibacterial UV coating is prepared from, by mass, 32-35 parts of castor oil base UV solidification urethane acrylate, 16-21 parts of organosilicone modification urethane acrylate, 8-10 parts of trimethylolpropane triacrylate, 5-6 parts of tripropylene glycol diacrylate, 15-16 parts of ethyl acetate, 14-15 parts of butyl acetate, 0.4-0.6 part of a polyether modified polysiloxane flatting agent, 2.5-3 parts of photoinitiator and 0.95-1 part of a nano-silver antibacterial auxiliary. The coating formed through a reaction between the polyether modified polysiloxane flatting agent and a mixed solution composed of the castor oil base UV solidification urethane acrylate and the organosilicone modification urethane acrylate in a cooperated mode is good in flatting effect, resistant to water and low temperature and more excellent in electrical insulating performance and adhesive force and is a coating which is good in comprehensive performance, and few volatile organic substances is emitted.
