Abstract
The invention relates to a production process of an interior wall coating, which relates to the field of chemical building materials and is mainly used for painting and decorating the inner surface of a building; the interior wall coating is fine and smooth, does not shed powder, has low cost and is popular with users.
Description
The production technique of new type interior wall coating of the present invention belongs to the building materials chemical industry field, and the internal surface that is mainly used in buildings is coated with brush finish.
The common building interior wall coating that now uses mainly be with polyvinyl alcohol as base-material or with the two kind interior wall coating types of rubber powder as base-material, be that the interior wall coating of base-material exists the cost height from polyvinyl alcohol, brush mark is arranged, easily precipitation; It is crisp hard with the rubber powder to be that the interior wall coating of base-material exists colloidality, easily explosion, the variable little yellow in brushing back.
The purpose of the production technique of new type interior wall coating of the present invention is to propose a kind of interior wall coating that adopts new formulation and processing method thereof.
Key of the present invention is to finish gelatinization technology by secondary stirring, and the rotating speed of stirrer is 600 rev/mins, thereby has solved the precipitation and the brush mark problem of coating; Simultaneously, adopt wilkinite and gelatinization technology also can reduce the consumption and the production cost of polyvinyl alcohol in right amount.
Accompanying drawing 1 is the schema of the production technique of new type interior wall coating;
1. coating dissolution process: the water that measures adds in the reactor, heats up to start and stirs, and adds the polyvinyl alcohol that measures when being warmed up to 40 ℃, and continuing to heat up 90 ℃ stops to heat up, and is incubated 1.5 hours and is cooled to 40 ℃ to be 8% concentration, and it is stand-by to go out still;
2. pulping process: with wilkinite and water in 1: 1.5 ratio park, soak add after 24 hours grind in the colloidal mill stand-by;
3. mixing stirring technique: add metering water in stirred pot, start is stirred, and adds bentonite slurry, lithopone, ground silica, talcum powder, fine particle calcium carbonate, starch, polyvinyl alcohol glue according to certain composition of raw materials proportioning and stirs.
4. the technology of milling: the mixed slurry that stirs carries out grinding technics through colloidal mill again.
5. gelatinization technology: the slurry after milling enters stirrer once more and stirs with 600 rev/mins, adds an amount of sodium hydroxide, tributyl phosphate carries out gelatinization and defoaming treatment.
6. packaging process: go into bucket through the slurry that secondary stirring is carried out after defoaming treatment is gone in gelatinization, cross claim, packing.
Technology of the present invention is simple, and required equipment is few, output needs one of 1～0.5 ton of reactor on a small scale; One in 600 rev/mins of stirrers, one of colloidal mill;
Raw materials technology of the present invention and proportioning thereof are: the polyvinyl alcohol glue of 8% concentration, starch, sodium hydroxide, wilkinite, lithopone, ground silica, talcum powder, fine particle calcium carbonate, water, phosphoric acid, tri-n-butyl are an amount of, are respectively 90,23,16,14,20,20,110～120,140,567～557, an amount of.
Interior wall coating of the present invention: meet quality testing standard through check, the user reflects that exquisiteness, smooth, not shedding, cost are low, becomes the NEW PAINT SYSTEMS FOR BUILDINGS of super quality and competitive price, receives praises from customers.
Claims (3)
1, a kind of production of Interior Wall Paint technology, realize by the formulation ratio that adjust to upgrade existing interior wall coating and technology thereof, after it is characterized in that polyvinyl alcohol and starch directly mixed, stir, grind, add an amount of sodium hydroxide and tributyl phosphate again and it is carried out secondary stirring finish gelatinization technology in stirrer, the rotating speed of stirrer is 600 rev/mins.
2, the production technique of new type interior wall coating as claimed in claim 1, the formulation ratio that it is characterized in that technology are that polyvinyl alcohol glue, starch, sodium hydroxide, wilkinite, lithopone, ground silica, talcum powder, fine particle calcium carbonate, water, the tributyl phosphate of 8% concentration is respectively 90,23,16,14,20,20,110～120,140,567～557, an amount of.
3, the production technique of new type interior wall coating as claimed in claim 1, it is characterized in that with wilkinite and water in 1: 1.5 ratio soak park 24 hours after, add grind in the colloidal mill stand-by.
