Description

A kind of water alcohol acid coating and preparation method thereof
Technical field
The present invention relates to painting technical fields, and in particular to a kind of high-performance water-based alkyd paint and its preparation side Method.
Background technique
Phthalic resin coating has good combination property, advantages at low cost, easy for construction and widely used etc., has been widely used Decoration and protection in the fields such as the buildings such as bridge and machinery, vehicle, ship occupy very big in coating industry total output Specific gravity.The volatile organic matter (VOC) that traditional solvent type coating generates in production or use process, not only can be to ecological ring Border pollutes, and brings injury to human body, and waste natural resources.With national environmental protection policies and regulations it is increasingly strict, disappear Expense tax and the collection of charges for disposing pollutants and gradually increasing for people's environmental consciousness, the development of water paint are more and more closed Note.
In recent years, water alcohol acid coating has been prepared by various methods both at home and abroad, film forming matter mainly includes water and milk Liquid type and water dilution type two major classes prepare high performance water alcohol acid coating and have become domestic rustproof lacquer researcher research Important directions.Many enterprises domestic at present are all proposed water alcohol acid coating successively.Since most of water alcohol acid applies in the market Material as film forming matter, has been used in the preparation process of coating and has largely been hazardous to the human body using water dilution type alkyd resin Organic cosolvent, such as butyl glycol ether, contact will affect the nervous system and reproductive system of human body for a long time；In addition water is used The problem of dilution type alkyd resin prepares water alcohol acid coating there is also poor water resistances；Meanwhile non-modified water is used merely The water alcohol acid coating comprehensive performance of dissolubility alkyd resin preparation is difficult to compare favourably with traditional solvent-borne alkyd coating, these factors The further genralrlization of water alcohol acid coating is seriously affected.
How to further increase the environmental-protecting performance of water alcohol acid coating, at the same improve the comprehensive performance of water alcohol acid coating with Traditional solvent-borne alkyd coating is substituted, becomes coatings enterprises and develops an aqueous alkyd paint problem urgently to be resolved.
Summary of the invention
For this high problem of traditional solvent-borne alkyd coating VOC content, a kind of high-performance water-based alkyd paint is provided, is subtracted Few pollution to environment, avoids harm of the organic solvent to human body.
It is a further object to provide the preparation methods of above-mentioned coating.
The present invention is realized by following technical proposals.
A kind of water alcohol acid coating, the raw material including following weight percent:
Further, the modified waterborne alkyd lotion is ALLNEX (profound new) AY6150W modified waterborne alkyd lotion, admittedly contain Amount is 40%~60%.
Further, the neutralizer is at least one of ammonium hydroxide, triethylamine or dimethylethanolamine.
Further, the dispersing agent is at least one in Digao TEGO 750W, TEGO 755W or TEGO 760W dispersing agent Kind.
Further, the defoaming agent is Bi Ke BYK 024, in Digao TEGO 810W or TEGO 902W aqueous defoamer It is at least one.
Further, the pigment is center titanium white R2196 titanium dioxide, Chongqing Jiangnan chemical industry F5RK red pigment or Ke Meisi One of YM07 yellow pigment.
Further, the levelling agent is Bi Ke BYK333.
Further, the aqueous drier is the DIC 3111 of DIC company, Japan.
Further, the substrate wetting agents are Digao TEGO Twin4100.
Further, the auxiliary rheological agents are moral modest 299.
Further, the anti-flash rusting agent is this chemistry of hamming FA179.
Correspondingly, The present invention gives a kind of preparation method of water alcohol acid coating, include the following steps:
1) 11~20% water, 0.1~0.6% neutralizer, 1.5~5% are added according to mass ratio in material-compound tank Dispersing agent and 0.1~0.3% defoaming agent, the speed with blender revolving speed for 600r/min stirs the mixture for uniformly, adding After entering 6~20% pigment dispersion 30min, 20 μm of fineness < are ground to sand mill；
2) mill base in step 1) is taken out, to sequentially add 0.3~0.5% under 800r/min revolving speed stirring Levelling agent, 55.5~73% modified waterborne alkyd lotion, 0.7~1.8% aqueous drier, 0.3~0.5% substrate profit Humectant and 0.5~1% anti-flash rusting agent, stir evenly；
3) it is slowly added to 0.3~1% auxiliary rheological agents under stirring, adjusts viscosity to 80 ± 5KU, filters, be made Water alcohol acid coating.
Innovation point of the invention: high-performance water-based alkyd paint prepared by the present invention is one kind with modified waterborne alkyd Lotion is film forming matter, VOC content ultralow (< 20g/L) and the environment-friendly type coating without harmful cosolvent；Gloss of film it is high and Have excellent salt fog resistance and artificial weathering aging performance, high-decoration and antiseptic property are incorporated into one, construction application Property is strong.The technology meets national energy conservation and emission reduction, environmentally protective policy requirements, meets that coating industry is environmentally friendly and Water-borne modification Developing direction, have biggish popularizing value.
