[background technology]
Paying close attention to more for iron plate coating people is ABRASION RESISTANCE and coefficient of friction under its high temperature.At present commercially available iron plate coating (market occupy volume data) usually adopts organosilicon coating.There is following problem in organosilicon coating: solidification temperature height has at first increased difficulty of construction and energy resource consumption; Its subsurface hardness especially case hardness under the high temperature is low, wears no resistance; The adhesion of organic silicon coating and aluminum ground is poor under the high-temperature vapor environment once more, and coating and ground are peeled off easily; And the organic silicon coating coefficient of friction is bigger, and general all greater than 0.30, smooth feeling is relatively poor during use.
For improving hardness, heatproof and the anti-wear performance of coating, reduce its coefficient of friction, the utility model provides a kind of coating of ceramic structure, and this coating and ground adhesion are good, but sintering under the low temperature, hardness height, heat-resistant, wear-resistant, coefficient of friction are low, excellent combination property.But heatproof is more than 400 ℃; The coating pencil hardness can reach more than the 7H under the normal temperature, and the coating pencil hardness can reach more than the 5H in the time of 200 ℃; ABRASION RESISTANCE is good; Coefficient of friction is low, less than 0.22.Effectively guarantee the service life and the smooth feeling of electric iron.

The base-material that constitutes coating has following component:
Colored paint has following component
Described auxiliary agent is as organosilicon modified polyorganosiloxane, phosphate modified acrylic acid etc.;
Described pigment is as titanium white, copper-chrome black, iron oxide red, phthalocyanine blue etc.;

Described catalyst is as zinc naphthenate, zirconium naphthenate, potassium acetate etc.;
Varnish has following component
Described auxiliary agent is as organosilicon modified polyorganosiloxane, phosphate modified acrylic acid etc.;
Described catalyst is as zinc naphthenate, zirconium naphthenate, potassium acetate etc.
With Ludox, ethyl orthosilicate, MTMS is raw material, adopts sol-gal process to synthesize base-material.Compounding aid, color stuffing and special catalyst can form the coating of ceramic structure at 200 ℃ of following sintering in this base-material.Owing to be rich in a large amount of silicon hydroxyls, coating and ground adhesion are very strong, efficiently solve organosilicon and are applied to the frequent foaming phenomenon (being that coating and ground are peeled off) that occurs on the iron plate.Coating is based on the inorganic constituents of silica silicon structure, so temperature tolerance is good, hardness is high, because coating surface is rich in methyl, so skin-friction coefficient is low, the smooth degree and the anti-wear performance of coating significantly are better than organic silicon coating simultaneously.
