Background technology
In recent years, the scientific and technical personnel of paint field have obtained certain achievement to the research of rust proof paint both at home and abroad, but less to the research of the antirust construction coating for internal wall of aqueous, environmental protective aspect.At present, when inner wall of building is decorate, before not brushing interior wall coating, hole for nailing is more, these holes for nailing do not brush rust-inhibiting paint just batch putty dry after, then swabbing, after half a year is hole for nailing rusty stain everywhere, ugly especially, has a strong impact on decorative effect.So, before batch putty, in hole for nailing, first brushes rust-inhibiting paint, then criticize putty dry after swabbing again, can solve like this hole for nailing rusty stain problem.But, if such technique is missed several holes for nailing, also there will be hole for nailing rusty stain problem.Therefore develop the coating that there will not be hole for nailing rusty stain phenomenon of osmosis after a kind of brushing, it is significant.
Summary of the invention
The object of the invention is the problem and the defect that for overcoming existing interior wall coating, exist, antirust construction coating for internal wall of a kind of aqueous, environmental protective and preparation method thereof is provided.
For achieving the above object, the present invention realizes the technical scheme that object adopts and is:
The antirust construction coating for internal wall of a kind of aqueous, environmental protective, each component forming and quality percentage composition be respectively: water is 25~30%, propylene glycol is 2~5%, GHS98A-302 organosilicon crylic acid latex 15~20%, the anticorrosion emulsion of GH-26XB silicon third is 12~16%, ultra-fine zinc phosphate calcium powder is 3~8%, WD-S-800 superfine composite ferrotitanium powder is 3~7%, ultra-fine rutile titanium white powder is 12~16%, superfine talcum powder is 5~12%, alcohol ester-12 (DN-12) are 2~5%, DA dispersion agent is 0.5~2%, GHP thickening material is 0.1~0.3%, water-based defoamer JS-R201 is 0.1~0.3%, sterilization
sanitaslC-18 is 0.1~0.3%.
The powder footpath of ultra-fine zinc phosphate calcium powder described above, WD-S-800 superfine composite ferrotitanium powder, ultra-fine rutile titanium white powder and superfine talcum powder is 1000 mesh sieves.
For achieving the above object, the present invention realizes another technical scheme that object adopts and is:
The preparation method of the antirust construction coating for internal wall of aqueous, environmental protective of the present invention, comprises the steps:
1. by formulating of recipe consumption, water, ultra-fine rutile titanium white powder, ultra-fine zinc phosphate calcium powder, WD-S-800 superfine composite ferrotitanium powder are added respectively in stirred vessel, with the rotating speed stirring 25-30min of 800r/min;
2. GHS98A-302 organosilicon crylic acid latex, the anticorrosion emulsion of GH-26XB silicon third are added in container, the rotating speed high-speed stirring 30-35min with 2000-2500r/min, then adds superfine talcum powder to stir 20-25min again;
3. more respectively by propylene glycol, alcohol ester-12 (DN-12), DA dispersion agent, GHP thickening material, water-based defoamer JS-R201, sterilization
sanitaslC-18 adds in container, and the rotating speed stirring at low speed 35-40min with 800r/min, obtains the antirust construction coating for internal wall of aqueous, environmental protective.
Advantage and beneficial effect that the present invention had are compared with prior art mainly reflected in:
1, coating VOC discharge of the present invention is zero, not containing heavy metal, environmental protection, have that fast drying, water-fast, acid and alkali-resistance, chemical resistance corrosion, abrasion resistance are good, the feature such as artificial weathering ageing resistance, strong adhesion, salt spray resistance, rustless property are strong, be widely used in building decoration anticorrosion, having unique corrosion-resistanting decoration effect, is the regeneration product of traditional rust-inhibiting paint.
2, after coating brushing of the present invention, there will not be hole for nailing rusty stain phenomenon of osmosis, decorative effect is good.
3, preparation technology of the present invention is simple, and cost is low, easily applies.
