A kind of F-C paint and preparation method thereof, raw material and preparation method including F-C paint, by weight percentage number meter, the fluorine
The raw material of carbon paint is as follows:
Remaining is deionized water.
Preferably, the preparation method of the F-C paint, concrete operation step are as follows: by each component deionization in formula
Water, dispersing agent, defoaming agent, titanium dioxide, fluorocarbon resin, sequentially add in reaction kettle and mix, and the revolution of blender is in mixing kettle
After the speed of 1500r/min is dispersed with stirring 30min, butyl acetate, hydrophobing agent, levelling agent, HDI isocyanates are sequentially added,
It is 35um that speed with revolving speed for 1200r/min, which is dispersed with stirring 30min to granularity, and finished product F-C paint can be obtained, finally carry out
Tinning.
Preferably, the titanium dioxide is rutile-type.
Preferably, the defoaming agent is polyethers defoaming agent, higher alcohols defoaming agent, silicon class defoaming agent and polyether-modified silicon
One or more of defoaming agent is constituted.
Preferably, the hydrophobing agent is the waterborne cation solution of polysilane.
Preferably, the dispersing agent is polycarboxylate sodium.
Preferably, each component weight proportion are as follows:
The beneficial effects of the present invention are:
1, by the way that hydrophobing agent is added in coating, hydrophobing agent is the waterborne cation solution of polysilane, can be in coating film formation surface
Forming a kind of special water-resistant structure makes surface have extremely strong hydrophobic, waterproof, hydrophobic, improve taste masking effect, to make VOC content
Low, environment-friendly type is strong.
2, HDI isocyanates is added in coating, both reduces volatility, higher molecular weight and degree of functionality but also applying
Expect easy quick-drying, mechanical property is good, chemicals-resistant and good weatherability, and adhesion strength is good.
