Abstract
The invention belongs to the building coating class.This crosslinked building coating, its main chemical constitution has polyvinyl alcohol, light calcium carbonate, auxiliary agent, filler, linking agent etc.The aqueous solution of the polyvinyl alcohol of weighing 4% is dropped into enamel pot heat up and make caking agent, in stirring, add linking agent and carry out modification and crosslinked, add defoamer, light calcium carbonate, talcum powder, add Sodium hexametaphosphate 99 liquid again, through grinding, sieve and make coating.This coating is applicable to the inside and outside wall coating of Industrial buildings, residential houses, school, shop, office building, auditoriums, hotels and various new and old building thing.
Description
The invention belongs to the building coating class.
It all is that the employing polyvinyl alcohol is that the raw material production building coating is (as 106 that multiple building coating is arranged at present both at home and abroad
#) all there are defectives such as water tolerance is bad.Be to solve water tolerance, take both at home and abroad polyvinyl alcohol is carried out hydrogenation, acetal, adds three steps such as polynary organic acid and handle and could solve its water tolerance.So the treatment time is long, the cost height, and (Japanese Patent also is to do like this) (580～690 yuan/ton) are reluctant to accept by producer.And the present invention carries out polyvinyl alcohol water solution modification one-step synthesis with linking agent, and the time is short, cost is low (330 yuan/ton), and thoroughly solves polyvinyl alcohol coating insoluble in water technical barrier.

The objective of the invention is to be developed into a kind of water-soluble modified to polyvinyl alcohol, technology is simple, one-step synthesis, and the time is short, and cost is low, the cross-linking type building coating that water-repellancy is extremely strong.
Cross-linking type building coating of the present invention, prescription contains (% calculates by weight): polyvinyl alcohol resin 3.0～6.5%, linking agent (being made up of zinc oxide, borax, boric acid, urea) is an amount of, auxiliary agent (tbp 0.01～0.04, six meta-acid sodium 0.2～0.5), filler (light calcium carbonate 28～30, talcum powder 4-8, zinc sulfide white 1～3), defoamer 0.009～0.01, dispersion agent 0.008～0.02, anti-settling agent 0.5～1.0, water 100, form.Compound method: the aqueous solution of the polyvinyl alcohol of weighing 4% is dropped into enamel pot heat up and make caking agent, in stirring, add linking agent and carry out modification and crosslinked, add defoamer, light calcium carbonate, talcum powder, add Sodium hexametaphosphate 99 liquid again, through grinding, sieving and make coating.
Its main raw material PVAC polyvinylalcohol polymerization degree general requirement about 1700, molecular weight is advisable about 10000, and the PVA resin content has certain influence to coating property, and if consumption is few, coating property is poor, and the polymerization degree is too little, and the film forming difficulty is soluble in water.For overcoming this weakness, by metal oxide is bridge, be equipped with alkaline salt, form linking agent, PVA is had the strongly hydrophilic hydroxyl carry out modification and crosslinked, just can make the complete aggegation of the PVA aqueous solution after the dissolving, producing stable viscosity, is medium by means of positively charged ion, and side chain increases, molecule increases, and hydrophilic group reduces.And the coating hydrophilic base played shielding effect, thus forming the inorganic organic hybrid films coating of cross-linking type, its water tolerance is extremely strong.The every technical indicator of coating of the present invention all meets the regulation of the ministerial standard JC361-85 of State Bureau of Building Materials Industry " polyvinyl alcohol water glass interior wall coating ".
The quality product performance satisfies following the requirement:
1. outward appearance: sticky shape, do not have caking through stirring
2. viscosity S:35-75
3. fineness km: be not more than 90
4. opacifying power g/m
2: be not more than 300
5. whiteness %: be not less than 80
6. appearance of film: smooth smooth, color and luster is even
7. sticking power: 100% does not have and comes off
8. water tolerance: the 24 hours coatings of soaking do not have come off, foaming, elephant skin, water insoluble.
9. thermotolerance: (80 ± 2 ℃) baking 5 hours, there is not the cracking phenomena that is clamminess.
10. anti-xerotripsis: be not more than 1 grade.
Advantage of the present invention: this coating is nontoxic, tasteless, nuisanceless, has good opacifying power, and sticking power is water insoluble through long period of soaking; Dried coating film is fast, and not shedding is not water funk; Easy construction, cheap.Be applicable to the inside and outside wall coating of new and old building things such as factory building, dwelling house, school, inn, office building, auditoriums, hotels and lime, cement, sand mud, plasterboard.
Most preferred embodiment:
Cross-linking type building coating, its prescription contains (% by weight): compositions such as 4% polyvinyl alcohol water solution 100, linking agent (being made up of zinc oxide, borax, boric acid, urea) 0.1, auxiliary agent (referring to defoamer, tbp 0.04, dispersion agent 10%, sodium hexametaphosphate solution 0.5), filler (referring to light calcium carbonate 26, talcum powder 4, zinc sulfide white 3), tap water 96.Compound method by above-mentioned use level, drops into the enamel reactor intensification with load weighted polyvinyl alcohol and makes the base-material caking agent, in stirring, carry out modification and crosslinked, add defoamer, light calcium carbonate, talcum powder, zinc sulfide white, add dispersion agent again, through grinding, sieving and promptly make coating.
