2. main tinting pigment is selected Rutile type Titanium Dioxide for use, belongs to color superfine white pigment, and stable to various chemical substances in the atmosphere, few to the absorption of light, its molten o'clock up to 1850 ℃.
3. flame retardant is selected ultrafine aluminium hydroxide for use, and molecular formula is Al (OH)
3Or Al
2O
3.3H
2O, water insoluble and alcohol is met high bake or when burned, promptly resolved into metallic aluminium ionic oxide formation thing and moisture content and discharge, and caloric receptivity is big, can reduce temperature, and has the effect that reduces poison gas and smog, and is simultaneously, cheap.
4. the pigment extender ultra-fine barium sulfate of selecting for use, chemical stability is good, and acidproof, alkaline-resisting, fast light, heat-resisting, fusing point reaches 1580 ℃, and oil number is low, and good dispersity can increase the tinting pigment opacifying power, do not influence gloss of film again, and price is low.
5. also selected for use two kinds of nano materials (particle diameter is less than 100 nanometers) to make auxiliary agent in this invention, the coating industry latest scientific research is that nano material is combined with the traditional coating industry, to improve the P/C ratio and the market competitiveness of coating, nano material is used for coating can obtains some specific functions, can improve the mechanical property of coating on the one hand, as paint film adhesion, shock-resistance, snappiness etc.Can improve ageing-resistant, corrosion-resistant, the radioprotective, automatically cleaning power of paint film, performance such as antistatic and fire-retardant on the other hand.
6. add 2% nano zine oxide (ZnO) in paint, the fungi-proofing property of mildew-resistant is best, though unglazed according under the condition, microorganism (bacterium, mould, virus, broadly also comprise algae and protozoon) is also had very strong sterilizing ability.Zinc oxide has good fast light, weathering resistance, not efflorescence, and Heat stability is good, its molten o'clock is nonpoisonous and tasteless up to 1975 ± 25 ℃, meets high temperature and does not decompose.
7. nano fumed silica (SiO
2) be unformed white powder, there is the hydroxyl of undersaturated residual bond and different bonding states in its surface, its molecularity is tridimensional network, with it be added on (only account for 0.5%) in the paint just can be to the varnish formation shielding effect, reach the purpose of anti-ultraviolet ageing and thermal ageing, increase thermal insulation, improve the suspension (promptly anti-precipitation) of pigment in the lacquer liquid simultaneously, the sagging phenomenon that paint may occur when especially having possessed precious thixotropy and can effectively guard against coating decoration.
Add nano-ZnO and SiO in the paint simultaneously
2Two kinds of components, good to contamination resistance and the washing fastness effect spy who improves paint film, the CPVC (critical pigment volume concentration in the lacquer) that can improve system simultaneously reduces the consumption of base-material, reduces poison gas and smog, reduces cost, and increases economic efficiency.Other performance can also be complementary, further improves the over-all properties of paint film.
8. selecting Synolac for use is good because of its coating decoration performance spy as base-material, and used solvent is to belong to No. 200 industrial napthas of low toxicity or claim the 200# varnish makers' and painters' naphtha, is commonly called as rosin.
9. it is as follows that light gray alkyd low flame spread hold paint of the present invention detects data:
Surface drying: 40min does solid work: 12h viscosity: 75s
Fineness: 35 μ m are shock-resistant: 50kgcm snappiness: 1mm
