In-tank antiseptic antimildew agent composition integrated with dry film for paint

Abstract

The invention relates to an in-tank antiseptic antimildew agent composition integrated with a dry film for paint. The composition is prepared from a water-based paint in-tank antiseptic bactericide, a dry film antimildew agent, a solvent, an aid, a stabilizing agent and water. The in-tank antiseptic antimildew agent composition integrated with a dry film for paint has the advantages of reasonable formula, advanced process, good corrosion and mildew prevention effects, good stability, and the like. When the in-tank antiseptic antimildew agent composition integrated with a dry film for paint is used for paint, salt cluster phenomena can be avoided, an in-tank antiseptic effect can pass a microorganism challenge test, and the dry film mildew-growing grade is a zero grade.

Description

technical field

[0001] The invention belongs to the technical field of preparation of chemical anti-corrosion and anti-mold agents, and relates to an anti-corrosion and anti-mold agent composition for water-based coatings in tanks and dry films and a preparation method thereof. Background technique

[0002] Water-based paints will be polluted and destroyed by harmful microorganisms in the process of production and storage, which will cause the paint to change color, flatulence, smell, demulsify, precipitate, and even lose its practical value. For many functional coatings or coatings used for special occasions, not only are the coatings required to be free from microbial contamination during production and storage, but they should also last as long as possible after the coating is painted to prevent bacteria, Mold and algae attack. For example, for hospitals, food processing places, bathing places, villa areas, house exterior walls (in most parts of southern my country), und...

Examples

Embodiment 1

[0046] Weigh 20 kg of CMIT / MIT hydrochloride, dissolve in 70 kg of deionized water, neutralize with alkaline agent sodium bicarbonate to pH 2-4, add 3 kg of sodium nitrate, filter, and make up to the total amount with deionized water 100 kg, spare.

[0047] Get 16 kilograms of above-mentioned mixtures, stir and add 4 kilograms of bronopol synergistic preservatives, obtain the coating preservatives in composite tanks.

[0048] Get 47 kg of 1,2 propylene glycol, add 3 kg of IPBC to dissolve; add 30 kg of OIT to dissolve, finally add 0.2 kg of nonionic surfactant TX-10 (auxiliary) and 0.2 kg of benzoyl peroxide (stabilizer) and stir evenly. Heat to dissolve if necessary; add 19.6 kg of preservative in the composite tank under stirring, disperse and stir for 30 minutes; filter with 100 mesh stainless steel mesh to obtain the inventive product.

Embodiment 2

[0050] Weigh 20 kg of CMIT / MIT hydrochloride, dissolve it in 70 kg of deionized water, neutralize it with alkaline agent sodium bicarbonate until the pH is 2-4, add 5 kg of potassium nitrate to dissolve, filter, and make up to the total with deionized water. The quantity is 100 kilograms, spare.

[0051] Get 20 kilograms of above-mentioned mixtures, obtain the coating preservative for cans.

[0052] Take 47 kg of 1,2 propylene glycol, add 3 kg of IPBC to dissolve; then add 30 kg of OIT to dissolve, and heat to dissolve if necessary; add 20 kg of paint preservative in the tank, 0.2 kg of TX-10 (auxiliary) and benzoyl peroxide under stirring 0.3 kg, dispersed and stirred for 30 minutes. Filter with 100 mesh stainless steel nets to obtain the invention product.

Embodiment 3

[0054] Weigh 16 kg of 50% MIT preservative, add 4 kg of bronopol to dissolve, control the pH to be 2 to 4, and take the above mixture to obtain a composite tank coating preservative.

[0055] Take 47 kg of 1,2 propylene glycol, add 3 kg of IPBC to dissolve; add 30 kg of OIT to dissolve, then add 0.3 kg of TX-10 (auxiliary), and heat to dissolve if necessary; add 19.7 kg of antiseptic in the composite tank while stirring, disperse and stir for 30 Minutes, filter with 100 mesh stainless steel nets, obtain the invention product.
