Description

Attapulgite washable inner wall paint
Technical field
The present invention relates to coating, be specifically related to a kind of attapulgite washable inner wall paint.
Background technology
Interior wall coating has some feature requests that are different from interior wall coating, and interior wall coating directly is coated on the internal surface of buildings or structures, and is more close with people's life or work relationship.The decorative effect of interior wall coating, the feel of filming, planeness and color, texture etc. can be subjected to people's more concern, interior wall coating can produce bigger influence to indoor environment, should have suitable ventilation property and water absorbability, airtight fully, nonhygroscopic filming can be caused the dewfall of metope, is unfavorable for the improvement of indoor environment and the raising of and comfortable for living.Can not contain poisonous, objectionable impurities in the interior wall coating, otherwise can work the mischief environment and health; Interior wall coating must have suitable water tolerance, alkali resistance and scrub resistance.
Chinese patent publication number CN 101077951, open day is on November 28th, 2007, name is called " a kind of is the environmental protection coating material of major ingredient with the attapulgite clay ", disclose that " a kind of is the environmental protection coating material of major ingredient with the attapulgite clay, the genus chemical field.Mainly solve existing coating aldehyde-containing type material and cause environmental pollution, endanger healthy problem.Its solids component comprises attapulgite clay, titanium dioxide, Mierocrystalline cellulose, gypsum etc.After mixing machine mixes, all saturating sieve.Above-mentioned raw materials is packed standby.Add water during use, fully mix, can directly smear, dry back or not drying all can allow the people to move in formaldehydeless harm.As interior wall coating, add fluorescent material, can make this coating seem bright at night.This kind is the environmental protection coating material of major ingredient with the attapulgite clay, do not use any batching that contains formaldehyde, thereby avoided the formaldehyde pollution fully, protected HUMAN HEALTH.”
The weak point of above-mentioned patent is to select for use the attapulgite clay of process purification and modification processing as main raw material in this technology, and its colloid viscosity, dispersiveness and suspension property are all poor, can have influence on the quality product of coating equally.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, a kind of attapulgite washable inner wall paint is provided.
Attapulgite washable inner wall paint is made up of paste attapulgite clay, nano aluminium oxide, polyvinyl alcohol ultrafine powder, quick dissolved sodium silicate, anatase thpe white powder, tributyl phosphate, fluorescent whitening agent VBL and deionized water.
The production method of attapulgite washable inner wall paint is: batching, pulverizing, stirring, dispersion, dissolving, homogeneous, emulsification, froth breaking, grinding, cannedly be the finished product of attapulgite washable inner wall paint.
Attapulgite clay is a kind of nanometer porous fibrous silicate clay mineral of Shuifu County's magnesium that contains, and when Attapulgite content 〉=80% in the attapulgite clay was above, its specific surface area was bigger, can reach 500m 2More than/the g.Use " wet beneficiation craft of Attapulgite " and " Attapulgite ore pul making production technique ", the screening of mineral such as the hydromica in the attapulgite clay, quartz, opal and carbonate is got rid of, obtain a kind of Attapulgite sludge slurry; Through the paste attapulgite clay after sodium processing and the acidification, it is the special good natural magnesium aluminium silicate gel of a kind of thixotropy and gumminess, it is neutral that the pH value is, and the viscosity of attapulgite clay, expansion capacity, colloid index, whiteness, specific surface area, absorption property and suspensibility all are greatly improved.
Attapulgite clay soil property exquisiteness, smooth surface, quality is lighter, is viscosity and plasticity-when moist, and its viscosity can reach more than the 3000mPas, helps the bonding between the raw material; The attapulgite clay drying shrinkage is little, and do not produce be full of cracks, can improve the sticking power of interior wall coating to building wall, paste attapulgite clay adds in the coating solution, forms stable not stratified gelinite under external force stirs fast, and viscosity and thixotropy are preferably arranged, the Photomicrograph that attapulgite clay coating is filmed shows, its crystal is netted arrangement, is evenly distributed in the coating, so the film coated surface wear resisting property is good.
Attapulgite clay has the selection adsorptive power, as polar molecule water, ammonia, methyl alcohol, ethanol, aldehyde, ketone, alkene, hydrocarbon etc. can be absorbed by access opening, then can not enter the duct to non-polar molecule such as oxygen etc., utilize this characterization of adsorption, formaldehyde and volatile organic matter in the energy absorbed air purify air.
The nano aluminium oxide crystalline phase is stable, hardness is high, behind the adding attapulgite washable inner wall paint, can play the wear-resisting hard effect that increases, and strengthens the mechanical property of coating, makes the use properties of coating more superior.
The polyvinyl alcohol ultrafine powder has good cold water instant dissolving, excellent film-forming properties, stronger cementability and perviousness, can improve the sticking power and the crocking resistance of attapulgite washable inner wall paint, prevents to produce efflorescence, chap and peel off behind the coating application.
Quick dissolved sodium silicate can be dissolved in water fast, behind the adding attapulgite washable inner wall paint, can infiltrate in slit and the hole, and solidified silicon gel can stop up capillary porosity duct, improves the density and the intensity of coating, thereby improves the wear resistance of interior wall coating.
Anatase thpe white powder has excellent water dispersible and remarkable optical property, form and aspect stability, size-grade distribution is good, behind the adding attapulgite washable inner wall paint, characteristics with high gloss, high reducing power, high covering power help producing the colour inner wall coating of various different colours.
Tributyl phosphate is a kind of defoamer, and defoaming effect is remarkable in attapulgite washable inner wall paint.
