Abstract

The present invention relates to external wall paint for buildings, which comprises the components by the weight proportion: 45 to 50% of emulsion, 30 to 20% of mineral stuffing, 5 to 15% of organic stuffing, 1 to 0.5% of wetting agent, 1 to 0.5% of dispersing agent, 2 to 4% of cosolvent, 0.3% of defoaming agent, 0.2% of mildew inhibitor, 2.5 to 3% of film-forming agent, 0.6% of thickening agent, 0.1% of rheologic auxiliary agent and water. Because air is carried in a paint film under the condition of low PVC which is less than CPVC, dry covering power is strong, and the paint film is continuous and complete. The paint film has the advantages of superior outdoor resistance, water resistance, abrasion resistance and storage stability. Therefore, expensive titanium white is not required, and costs are low. During color matching, color paste is saved, compatibility is good, and colors are brilliant.

Description

Outer wall dark colour mixer paint with no titanium pigment

The present invention relates to chemistry painting industry, exterior wall chemistry painting industry particularly for building.

Tinter commonly used on the construction market because the low dark colour mixer paint of PVC content often has opacifying power not enough, and has to add an amount of titanium white at present.After adding titanium white, the toning of lacquer, weathering resistance reduce.Because tinter is because of the mismatch of material in the prescription in the market, make the hydrophilic and oleophilic imbalance of system, there is mutual repulsion in the system, pathology such as feasible lacquer in use is prone to loose colour, grow dim, often occur wild effects such as loose colour, layering, precipitation in the storage process, thereby make the performance off-design target value far away of lacquer.In the ordinary course of things, add a large amount of titanium whites and can increase the absorption ultraviolet ray, and can improve its weathering resistance.And a spot of titanium white not only can not function as described above in dark colour mixer paint, can colour killing make color be difficult to transfer deeply on the contrary, makes the deepening of color variable ash, the color muddiness, and tone deepening, vividness reduce.In addition, titanium white absorption ultraviolet ray generation oxyradical, hydroxyl free radical have reduced the weathering resistance of exterior wall on the contrary.Because the titanium white price is higher, it is little to add the effect lacked, and it is not only high to have added expense, also can bring some negative interactions thus.

The objective of the invention is to: a kind of expensive titanium white, outer wall dark colour mixer paint with no titanium pigment that has good dry hiding power, water tolerance, anti-outdoor performance again of not using is provided.

It is by weight percent 45-55% emulsion; The mineral filler of 20-30%; The solubility promoter of the dispersion agent of 0.5-1% wetting agent: 0.5-1%: 2-4%: 0.3% defoamer: the membrane-forming agent of 0.2% mould inhibitor: 2.5-3%; 0.6% thickening material; 0.1% auxiliary rheological agents; All the other are formed for water.

Used emulsion is phenylpropyl alcohol or pure third.

Used mineral filler is coarse whiting, wollastonite, kaolin, mica etc.

Used organic filler is B-98 or OP-62B.

Used wetting agent is Hydropalat436.

Used dispersion agent is SN-Dispesant5027.

Used solubility promoter is a propylene glycol.

Used defoamer is Nopco8034L.

Used mould inhibitor is DehyguntLFM.

The used film forming agent is Texamol.

Used thickening material is SN-Thickener636, SN-Thickener612D.

Used auxiliary rheological agents is LerellingG620.

The present invention has fabulous toning.Usually the producer that produces emulsion paint does not produce mill base, and the producer that produces mill base does not produce emulsion paint yet, but two kinds of different manufacturers, different classes of, the product of same-action is essential again uses preceding blending together, if there be one or two hydrophile-lipophile balance value higher or on the low side in the mill base, its toning property is just bad, has used the colored paint of this mill base to grow dim by loose colour.Because toning of the present invention is good, can be compatible with the mill base of most producers brands, when the design paste formula, can this tinter as the standard paint sample of check color paste toning performance.

Owing to be at low PVC, under the situation of PVC＜CPVC air is brought in the paint film, so dry hiding power is strong, the paint film continuous whole, its outdoor patience, water tolerance, abrasion resistance, package stability etc. are all very superior, because of there not being expensive titanium white composition, price is lower, has both saved mill base and bright in luster during toning.

During preparation:

Earlier that an amount of water, wetting dispersing agent, defoamer, mould inhibitor, mineral filler is scattered in container, sand milling is to fineness＜30 μ m after-filtration, adjust pH value and viscosity the gained slurries add film coalescence aid, emulsion, organic filler and thickening material, rheology modifier under constantly stirring after to desired value, get product after the filtration.
