Description
Technical field
The invention discloses a kind of preparation method of exterior wall latex paint, belong to paint field.
Background technology
The major function of exterior wall latex paint is decoration and protection building surface, makes building appearance neat and artistic, so as to reach
It to the purpose of beautifying urban environment, while can play a part of protecting skin, extend its service life.Jie is used as using water
The exterior wall latex paint of matter more meets green requirement compared with solvent type exterior wall coating, and the volatility that the latter contains more than 40% is molten
Agent, wherein being largely cheap dimethylbenzene, No. 200 industrial napthas, these toxic solvents all volatilize with the film forming of coating
Into air, waste of resource, pollution environment, and plasticiser component in its formula, it is the material similar to female hormone mostly,
It is very big to male's injury.The major function of exterior wall latex paint is decoration and protection building surface, makes building appearance neat and artistic,
It so as to reach the purpose of beautifying urban environment, while can play a part of protecting skin, extend its service life.
With the development of construction industry, exterior wall latex paint is with its excellent dicoration, durability, easy construction and good property
Valency is welcome than increasingly by market, turns into the main material of decorating inner and external walls, but cracking often occurs in building exterior wall surface
Line.These crackles do not only result in flaking, coming off for emulsion paint coating, can also cause exterior wall sweat sometimes, have a strong impact on breast
The decoration performance of shellac varnish.Several reasons for being easily caused exterior wall cracking are as follows：1. wall cement mortar plastering layer ftractures, so as to cause
Putty and emulsion paint coating cracking；2. coat of plaster does not ftracture, putty ftractures in the drying process；3. emulsion paint is of poor quality, it is impossible to
Resist the fine crack of basic unit；4. exterior wall latex paint construction method is improper.Because the duration is tight when 5. exterior wall latex paint is constructed, wall face
Moisture content is big, moist.Enter paint application too early, influenceed to have caused drum, peeling by high temperature after painting back cover；6. exterior wall latex
The material property of paint, i.e., non-resilient putty and oiliness topcoat material for the anti-shrink of exterior wall slightly chap performance also have it is certain
Influence；Secondly, the problem of exterior wall latex paint is in the prevalence of durability of coating difference poor adhesive force.Coating through wind, drench with rain, Exposure to Sunlight
Process, extraneous various pollutants are adsorbed or adhered to, had a strong impact on the decorative effect of building；Coating due to weatherability difference and
Prematurely produce efflorescence, discoloration, colour fading, loss of gloss, coating shedding phenomena such as, have impact on to some extent building aesthetic property and
Durability.Thus, the popularization and application process of China's exterior coating is constrained.
With being in full swing for urban renewal, housing industrialization, urbanization and new countryside construction, with Building Energy-saving Work
Implementation, preparation has a preferable weatherability, anti-crack ability and the high exterior wall latex paint of adhesive force, will win users'
Favor.
The content of the invention
The present invention solves the technical problem of：It is poor for traditional exterior wall latex paint weatherability, anti-crack ability difference and
A kind of the shortcomings that adhesive force is low, there is provided preparation method of exterior wall latex paint.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
50~60 parts of water-soluble resins, 30~40 parts of water, 10~12 parts of additives, 8~10 parts of pigment, 3~4 parts of surface-actives
Agent, 3~5 parts of wetting agents；
The exterior wall latex paint concretely comprises the following steps：
（1）Additive：By diatomite and water in mass ratio 1：5~1：8 mixing, add the metal powder of 0.2~0.3 times of water quality
End, the mussel foot albumen of 0.3~0.4 times of water quality is added after being stirred, continues to stir, concentrated, obtain concentrate, produce addition
Agent；
（2）By water-soluble resin, after additive and water are stirred under relatively low rotating speed, pigment is sequentially added, surface is lived
Property agent and wetting agent, and be stirred at higher rotational speeds, it is to be mixed uniformly after, paint vehicle is stood, produces exterior wall latex paint.
Step（1）The metal dust is any one in aluminium powder or magnesium powder.
The water-soluble resin is any one in emulsion acrylic resin or styrene-acrylic emulsion.
The pigment is any one in organic pigment or inorganic pigment.
The surfactant is any one in castor oil polyoxyethylate amide or AEO.
The wetting agent is any one in sulfonated oil or soybean lecithin.
The beneficial effects of the invention are as follows：
（1）The present invention adds diatomite and metal dust in additive, on the one hand, diatomite is added in additive to be increased
The active force of each molecule interchain, makes emulsion paint not easy to crack in strong emulsion paint system, and weatherability improves, and due to diatomaceous
Strong adsorptivity, the pigment in paint vehicle can be made more scattered, Adhesion enhancement of the paint vehicle on metope, on the other hand, added
The metal dust added in agent can be scattered in whole binder system by kieselguhr adsorption, due to metal dust in atmosphere
Oxidation, form layer of metal protective oxide film in lacquer surface so that the weatherability of emulsion paint is obviously improved；
（2）The present invention adds mussel foot albumen in additive, and first, mussel foot albumen has stronger viscosity, adds people's latex
After in paint system, it can further enhance the intermolecular active force of water-soluble resin in system, so that emulsion paint is resistance to
Time property and anti-crack ability get a promotion, and secondly, mussel foot albumen can strengthen the active force between paint vehicle and metope, be not easy paint vehicle
Come off, and after surface protein inactivation, the protein of inactivation can form one layer of protection by kieselguhr adsorption in lacquer surface
Layer, and then further lift the crack resistance and weatherability of emulsion paint.
