A kind of steel ceramics-like coating
Technical field
The present invention relates generally to a kind of coating, relates in particular to a kind of steel ceramics-like coating.
Background technology
That coating should have is anticorrosion, waterproof, grease proofing, chemicals-resistant, fast light, heatproof etc., and object is exposed among atmosphere, is subject to the erosion of oxygen, moisture etc., causes the breakoff phenomenons such as corrosion of metal, foxiness, cement weathering. Be coated with coating at object surface, form layer protecting film, can stop or postpone generation and the development of these breakoff phenomenons, extended the service life of various materials. So protective effect is a Main Function of coating, improve the protective effect of traditional coating, could further improve the quality of coating.
Summary of the invention
The object of the invention is exactly for a kind of steel ceramics-like coating is provided.
The present invention is achieved by the following technical solutions:
A kind of steel ceramics-like coating, it is made up of the raw material of following weight parts:
Polyvinyl acetate emulsion 10-12, methylcellulose 5-7, glass fibre 4-6, graphite powder 10-20, calcium hydroxide powder 20-30,3-aminopropyl trimethoxysilane 1-2, magnesia 3-5, GDMA 2-3, tributyl phosphate 0.1-0.4, adhesive aid 5-10, deionized water 40-50;
Described adhesive aid is made up of the raw material of following weight parts:
Benzene emulsion 60-70, bassora gum 6-8, ZPT 1-2, sodium silicoaluminate 4-6, butyl polyacrylate 1-2, hydroxyethylcellulose 2-4, BHT 0.1-0.3, water are appropriate;
The 10-20% of above-mentioned weight bassora gum is joined in 10-15 times of water, add hydroxyethylcellulose and BHT, dispersed with stirring 10-15 minute under the speed of 400-600 rev/min, rising temperature is 60-80 DEG C, add ZPT, sodium silicoaluminate, butyl polyacrylate, after fully mixing, add the each raw material of residue, after stirring, cross the Steam Heating of 80-100 DEG C, the system solid content of making is 60-65%, is cooled to normal temperature, obtains described adhesive aid.
A preparation method for steel ceramics-like coating, comprises the following steps:
(1) above-mentioned polyvinyl acetate emulsion is mixed with the 50-55% of above-mentioned weight deionized water, fully stir;
(2) methylcellulose is mixed with remaining deionized water, fully stir;
(3) above-mentioned each raw material after treatment is mixed, add adhesive aid, insulated and stirred 10-20 minute at 70-80 DEG C, is cooled to normal temperature, adds tributyl phosphate, adds the each raw material of residue after stirring, and fully grinds, and obtains described steel ceramics-like coating.
Advantage of the present invention is:
Product of the present invention has fabulous decorate properties, smooth in appearance, and firm in porcelain, water-fast, acid-alkali-corrosive-resisting, resistant of high or low temperature are strong, and film is stable, has good protection effect.
