Description
Technical Field
The invention belongs to the technical field of anticorrosive coatings, and particularly relates to a manufacturing method of an anticorrosive coating.
Background
Latex paints, resin emulsions, and waterborne coatings all contain organic materials that provide the basic conditions for the growth and proliferation of microorganisms. Under proper conditions, the growth and the propagation of a large amount of microorganisms can be promoted, and in the process, metabolic products such as enzymes and organic acids generated by the microorganisms can cause the change of the smell, the color, the viscosity and the like of the coating, so that the product is deteriorated.
The mildew inhibitor can inhibit the growth of microorganisms, and a proper amount of preservative can be added into the product to effectively prevent the invasion of the microorganisms. There are a number of preservatives currently on the market, such as BCM, OIT, IPBC, IPN (CLT) and DCOIT. Wherein DCOIT is 4,5-dichloro-2-n-octyl-7-isothiazolin-3-one, and the structural formula is as follows:
DCOIT can be used for dry film mildew resistance and can also be used for in-tank corrosion resistance, and is a broad-spectrum efficient corrosion, mildew and algae resistant agent. However, with the long-term use of DCOIT, many microorganisms have developed resistance to it, resulting in a gradual decrease in the inhibitory effect on their various molds. In production, although the inhibiting effect on microorganisms such as bacteria, fungi, algae and the like can be improved by adding the additive amount, DCOIT has larger skin irritation and is a chlorine-containing product, and the increase of the dosage can cause the application amount to exceed the standard and cause damage to human bodies.
In the paint industry, different anticorrosive components can be combined and compounded in different proportions, and the synergistic effect can improve the mould inhibition effect, reduce the dosage and reduce the cost. CMIT/MIT + FR is a very common combination compound which has high-efficiency broad-spectrum bactericidal action, but can not achieve the effect of synergistic action by combining and compounding any two or more antiseptic components.
The inventor discovers that the DCOIT and the murrayone can improve the inhibition effect on various moulds when being combined and used according to a certain mass ratio through an indoor synergistic test, so that the consumption of antiseptic components can be reduced, the cost can be reduced, and the life health safety of people can be protected. Chinese patent CN202210498785.1 discloses a preparation method of an architectural coating, and particularly discloses that when isothiazolinone and murrayone are used in combination, the inhibition effect on mold can be improved. At present, no report on the combined use of DCOIT and murrayone is found.
