Abstract
The method relates to a coating capable of quick-drying at normal temperature and resisting corrosion and a preparation method thereof. The coating comprises the following components by weight ratio: 80 parts of liquid maleate polybutadiene, 10 parts of ethylene glycol dimethacrylate, 10 parts of tetrahydrofurfuryl alcohol, 80 parts of titanium dioxide, 1.0 part of cobalt naphthenate and 2.5 parts of methyl ethyl ketone peroxide. The coating consisting of organic matters is prepared by mixing the components and has the following superior physical properties: the coating is dry-to-touch within 3h and completely cured within 6h with the thickness of the cured coating being mum at room temperature; the pencil hardness of the coating is 2H; the impact strength thereof is higher than 50 according to the Dupont impact tester; the adhesion thereof is 7.5mm according to the Erichsen tester; the coating is qualified according to the cross-cut test; and the coating is corrosion resistant, particularly, no abnormality like rust is detected after 200h, the coating is qualified according to the waterproof test at 40 DEG C after 400h, and no abnormality is detected according to the test in the water solution of sodium hydroxide (5%) at room temperature for 24h. Accordingly, the coating of the invention constituting a low-viscosity high-build coating capable of self-curing at normal temperature is applicable as anti-corrosive and protective coatings in the construction based on the conventional coating construction method.
Description
Technical field:
The invention belongs to a kind of coating and preparation method thereof. be particularly related to a kind of normal temperature quick-drying protective system and preparation method thereof.
Background technology:
The present coating that is used for the surface, metallize, the effect of spraying is undesirable, has defectives such as poor, the easy stroke part of visual appearance, wound easy to wear, gloss dimness, thereby has influenced the visual appearance and the image appearance of metal sheet.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, and a kind of spraying that is easy to is provided, and scribble effect is good, and the normal temperature quick-drying protective system of spraying rear surface light.Technical scheme of the present invention is: the coating weight ratio consists of 80 parts of maleinization liquid polybutadienes, 10 parts of ethylene glycol dimethacrylates, 10 parts of tetrahydrofurfuryl alcohols, 80 parts of titanium whites, (6%) 1.0 part of cobalt naphthenate, methylethyl ketone peroxide 2.5.
The component thorough mixing makes coating in will filling a prescription.
Advantage of the present invention is:
1, because the selected raw material of this product is an organic compound, do not contain heavy metal, nontoxic pollution-free.2, the rich texture of paint film, friction can not produce static, and good water tolerance, elasticity, snappiness, chemical resistant properties, wearability are arranged.Product contains 60% admittedly, and hiding rare height, surface covered are big, and unit usage quantity relative cost is low.3, being applicable to the metallic surface spraying, is that safe antistatic protection is with coating with lacquer.
Embodiment:
With maleinization liquid polybutadiene 80kg, ethylene glycol dimethacrylate 10kg, tetrahydrofurfuryl alcohol 10kg, titanium white 80kg, cobalt naphthenate (6%) 1.0kg, methylethyl ketone peroxide 2.5kg thorough mixing makes coating.
Under the gained coating room temperature 3h refer to touch dried, 6h completely solidified, cured coating film μ m, pencil hardness 2H, Du Pont impacts more than 50, and dust is made every effort to overcome gloomy test 7.5mm, and cross cut test is qualified, the rerum natura of filming is very excellent, the erosion resistance of filming, finding behind the 200h gets rusty waits unusually, qualified behind 40 ℃ of water-fast 400h, 5% aqueous sodium hydroxide solution room temperature 24h, it is no abnormal to film.This coating is the thick coating of ambient cure low viscosity.
Can be by general coating decoration method construction.
As anticorrosion, protective cover.
