Summary of the invention
The object of this invention is to provide a kind of preparation method of epoxy anticorrosion antibiotic paint, utilize preparation method of the present invention, the epoxy anticorrosion antibiotic paint that a kind of antiseptic property is good, impact resistance is good, good toughness, anti-microbial property are good can be prepared, and technique is simple.
For achieving the above object, a kind of preparation method of epoxy anticorrosion antibiotic paint, according to weight percent meter, comprises the steps:
(1) take 15%-23% deionized water respectively, antibacterial modified resin and nano-silicon solution, 5%-10% urethane, 10%-18% nitrile rubber, 0.5%-0.9% dispersion agent, 0.4%-0.8% defoamer, 0.4%-0.8% sanitas that 30%-40% bisphenol A epoxide resin, 8%-15% phenolic aldehyde amine, 5%-10% weight percent are 30:1, and together join in dispersion tank, under the rotating speed of dispersion tank 300-500r/min, dispersion is stirred after 5-10 minute and is obtained mixture;
(2) the sheet high abrasion color stuffing and the 0.2%-0.5% flow agent that take 10%-17% join in described mixture, and under the rotating speed of dispersion tank 1000-1500r/min, dispersion is stirred after 10-15 minute and obtained epoxy anticorrosion antibiotic paint.
Further, described sheet high abrasion color stuffing by 320 orders and content be the glass flake of 2%-4%, the sericite in powder of 160 orders and content to be the glass flake of 3%-6% and content be 5%-7% forms; Above per-cent is all weight percentage.
Further, described dispersion agent is TH-904 or SN-5040.
Further, described defoamer is SN-154 or A10.
Further, described flow agent is RM-2020.
The invention has the beneficial effects as follows: phenolic aldehyde amine, can fast setting at low ambient temperatures as solidifying agent, and has good antiseptic property; The benzene ring structure of this solidifying agent and bisphenol A epoxide resin have better consistency, thus can reduce the viscosity of system further, improve the compatibility of host and solidifying agent.Bisphenol A epoxide resin and paracril first carry out pre-reaction, adding of a small amount of paracril can not form two phase structure, the formation when paracril content reaches certain limit is only had to have being separated of island structure, this can meet uncured front rubber and bisphenol A epoxide resin well miscible, low viscosity characteristics, can rubber phase be separated out after can solidifying again again, produce micron-scale phase separation, improve impact resistance.Urethane and bisphenol A epoxide resin can form semi-intercrossing network (SIPN) and interpenetrating(polymer)networks (IPN) polymkeric substance, SIPN and IPN structure desirable " forcing mutual tolerance " and " synergy " make the snappiness of urethane and the good heat resistance of bisphenol A epoxide resin and cementability organically combine, and obtain good toughening effect.By coatings of the present invention on body of wall, due to the interaction of antibacterial modified resin, nano-silicon solution and bisphenol A epoxide resin, make the anti-microbial property of this coating good, and have good heat-proof quality, the hardness of paint film is high, good toughness.And technique is simple.
