Abstract
The present invention relates to environmental protection type nano coating which is characterized in that the coating comprises nano grade materials, film forming auxiliary agent, dispersant, stiffening agent, defoaming agent and ammonia water, wherein the nano grade materials comprise titanium pigment, calcite, grammite and color paste. The desired product can be obtained by uniformly stirring in high speed. The product of the present invention has the advantages of no poison, no environmental pollution, smooth and shining face layers after construction, soft color, water resistance, flame prevention, high temperature resistance, no deposition, no layer separation, low cost, etc. Thus, the present invention provides environmental protection type coating.
Description
Technical field
The present invention relates to technical field of coatings, more particularly, is a kind of environment friendly nano coating composition.
Background technology
In recent years, along with China's rapid development of economy, building decoration and building coating industry also obtain develop rapidly, and some new coatings are also come out one after another.But, from the existing coating of China on the whole, still exist defective in use and decoration functions, though various as the exterior coating color, the ubiquity suspension stability is poor, and thixotropy is poor, and is not ageing-resistant, and smooth finish is not high; Difficulty of construction is after-tacked greatly and easily, easily loss of gloss, yellowing, fades; That have even poisonous, contaminate environment.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, propose the environment friendly nano coating that performances such as a kind of toughness, ageing-resistant, waterproof all have raising.
Main technical schemes of the present invention: adding wraps in titanium dioxide, water-ground limestone, wollastonite in interior nanometer materials in coating composition, thereby changes and improve some character of coating.
The combination of coating of the present invention and parts by weight thereof:
Titanium dioxide 90-95 part, calcite 90-95 part, wollastonite 190-195 part, film coalescence aid 13-15 part, dispersion agent 3-5 part, ammoniacal liquor 2-32.5 part, Natvosol thickening material 2-11 part, defoamer 1-2 part, benzene emulsion 285-290 part, mill base 7-10 part, water 285-295 part.
Titanium dioxide of the present invention is TiO
2, relative molecular weight 79.88, density 3.9-4.2g/cm
3, stable chemical performance, white pigment is nanometer materials.
Calcite of the present invention is a water-ground limestone, and relative molecular weight is 100.9, and the thin sprills of nano level of white are as stopping composition.
Wollastonite of the present invention requires more than No. 96, and fineness is a nano level, as filler.
Film coalescence aid of the present invention, its trade names are alcohol ester-12, and purpose makes the rapid film forming of base-material.
Dispersion agent of the present invention, its trade names are OP-10, and purpose is the bond state of regulating base-material.
Thickening material of the present invention is a Natvosol, and purpose is help emulsion miscible.
Ammoniacal liquor of the present invention, pH value are 7.3-7.8.
Defoamer of the present invention, its trade names are spa-202, are the translucent thick liquid of light color to light brown.
Phenylpropyl alcohol supernatant liquid of the present invention, trade names are HYS-08, are a kind of liquid that helps.
Mill base of the present invention, according to service requirements allotment different colours mill base, requirement is nano level mill base.
The used starting material of coating of the present invention all can buy on market.
Preparation method for coating of the present invention comprises following process:
(1) 285-295 part water, 3-5 part dispersion agent, 1-2 part defoamer are mixed, under 2000 rev/mins rotating speed, stir,
(2) in the mixture of step (1), under 35-45 ℃, add titanium dioxide 90-95 part, calcite 90-95 part, wollastonite 190-195 part is stirred to no granulated,
(3) in the mixture of step (2), add benzene emulsion 285-290 part, mill base 7-10 part again, stir, treat that the qualified after-filtration of every index is detected in its cooling back, encapsulation is desired product.
Advantage of the present invention and effect:
Owing to added the nanometer materials that comprise titanium dioxide, calcite, wollastonite, therefore, have following characteristics in the coating composition of the present invention:
1. product of the present invention does not have organic solvent, so non-environmental-pollution.
2. with the surface layer behind the coating application of the present invention level and smooth light, exquisite in texture, advantage such as color and luster is soft and have waterproof, fire-retardant, and is high temperature resistant.
3. purposes is wide, is not only applicable to the interior exterior wall of buildings, and available water-proof material.
4. easy construction, coating of the present invention does not after-tack, can brush, spraying, roller coating, color can be allocated arbitrarily according to purposes and client's needs.
5. product cost of the present invention is low, storing safety, and do not precipitate, not stratified.
Product performance data of the present invention see Table 1.
Embodiment
Further specify characteristics of the present invention below by specific examples.
