Abstract
A novel environment-friendly waterborne baking varnish for coiled materials is applicable to the replacement of solvent-based coatings used by coiled material manufacturers. The components comprises, by weight: 300-400 of waterborne polyester resin; 300-350 of water; 50-100 of amino resin; 150-200 of pigments and fillers; 0.5-1 of wetting agents; 1-2 of defoaming agents; 3-5 of dispersants; 10-20 of propylene glycol methyl ether; 10-20 of propylene glycol butyl ether; 2 of leveling agents. Compared with solvent-based products used in existing coiled material industry, the product mainly uses water as a dispersion medium, and the used cosolvent belongs to propylene glycol ether which is a friendly organic solvent for human body, so the product is environment friendly. The bodies of constructors are protected from invasion of poisonous volatile compounds, and the performance indices of the product, such as luster, impact resistance, solvent resistance, weatherability, T-bend, adhesion, hardness and the like, are comparable to the performance of solvent-based coatings.
Description
Technical field
The present invention relates to a kind of industrial water-borne coatings
Background technology
Coil coating application colour coated plate has become very big industry abroad, and the development of domestic colour coated plate in recent years is very rapid.At present, the coil coating technology mainly develops to extra long life, product functionization and environmentally friendly direction, and promotes the technical progress of color-painted steel strip and the continuous expansion of Application Areas.
The base material of coil coating has cold-rolled steel sheet, hot-dip galvanizing sheet steel, electrogalvanizing steel plate, aluminium zinc plate and aluminium sheet etc., and thickness is between 0.1～0.5mm.
In more than ten years in the past, the colored steel industry of China is grown out of nothing, actual working rate wretched insufficiency, and the excessive competition of colored steel industry faces low-end market, and high-end market needs the difficult situation of a large amount of imports.Domestic also being in the continuous process that enlarges of coloured coating plate Application Areas, generally, the demand in market is still vigorous.Coloured coating plate for building accounting on international color paint sheet market is 60%～70% heavily, and China accounts for more than 90%, though Application Areas is in expansion as can be seen, building is still main users.The production capacity total amount has been higher than the desired consumption demand, and high-grade color steel is more and more looked at by Chinese building material market parent, and household electrical appliances are increasing year by year with the demand of color steel, and have given new function, as antimicrobial surface.Household electrical appliances are very big with plate market, and refrigerator, air-conditioning, washing machine, refrigerator etc. take very big market, and domestic color steel will capture this market also need descend some time, but market is huge.
Existing coil coating can be divided into three major types: (1) priming paint: priming paint is divided into polyester-amino priming paint according to the film-forming resin difference, polyester-polyurethane priming paint, epoxy-amino priming paint, epoxy-polyurethane priming paint, (2) finish paint: use oil-free polyester resin.Crosslinking curing uses methyl-etherified aminoresin.(3) back side lacquer: use at the back side at the coil plate, can be coated with or do not prime, therefore requiring has good sticking power, though over-all properties requires not as good as the finish paint height, is better but adopt the resin manufacture identical with finish paint.
Although coil painting has many advantages, as increasingly automated, efficient is high, steady quality etc., the organic volatile in the coating (VOC) is after baking, through collecting burning, heat utilization ratio reaches more than 97%, is a kind of coating process of environment-friendly type.But,,, therefore reduce VOC even zero VOC is one of developing direction of environment-friendly type coil coating along with people improve the cognition of own healthy living and work because the solvent-borne type liquid coating need consume a large amount of organic solvents.
Summary of the invention
VOC content height at the existence of solvent-borne type coiled material baking vanish, big to person injury, coating uses later, and machine cleans difficulty, along with oil price raises, the organic solvent price is ascended to heaven, and causes enterprise to clean the disadvantage that cost further strengthens again, the invention provides a kind of novel environment-friendly water-based polyester coiled material baking vanish prescription, this kind product meets the requirement of country to the environment-friendly property of product, meets enterprise and produces needs, effectively replace solvents type coating
For achieving the above object, technical solution of the present invention is:
A kind of novel environment-friendly water-based polyester coiled material baking vanish prescription, as dispersion agent, its each set of dispense ratio is: aqueous polyester resin 300-400 with water for it; Water 300-350; Aminoresin 50-100; Color stuffing 150-200; Wetting agent 0.5-1; Defoamer 1-2; Dispersion agent 3-5; Propylene glycol monomethyl ether 10-20; Propylene glycol butyl ether 10-20; Flow agent 2.
The technique scheme advantage is:
, nontoxic behind the film curing moisture evaporation with water to the person as dispersion agent, as clean-out system, can clean cost with water for enterprise reduces, substitute organic solvent, and then reduce the organic solvent usage quantity more.This kind product does not also contain heavy metal, is beneficial to health of human body more, and its paint film is at gloss, shock resistance, and anti-solvent, weathering resistance, T is curved, adheres to, and reaches the solvent based coating performance on the indexs such as hardness.On depositing, owing to make water, do not fire and do not possess chemically reactive as dispersion agent, stable storing, safe and reliable.
