Description
Technical field
The invention discloses a kind of special wall coverings of aerial fog type water-based exterior wall, belong to technical field of coatings.
Background technology
Exterior coating can be divided mainly into water soluble coating and emulsion paint.Exterior wall latex paint basic performance and interiro wall latex paint difference are not
It is more.But paint film is harder, and water resistant ability is stronger.Exterior wall latex paint is generally used in exterior wall, can also be used in the climaxes such as toilet
Wet place.
There are many type of exterior coating, can be divided into the antiacid alkali exterior coating of strength, and elastic pure acrylic acid exterior coating has
The self-cleaning elastic exterior coating material of machine silicon, advanced acrylic wall paint, fluorocarbon coating, rural scenery series of low-carbon etc..It is used extensively
In brushing facade, so a most important index is exactly ultraviolet radiation resisting, it is desirable that reach for a long time irradiate it is constant
Color.Exterior coating also requires have water repelling property, it is desirable that has self-cleaning.
Paint film wants hard and smooth, dirty once rushing.It is because it also has that exterior coating, which can be used for interior wall brushing use,
Water repelling property, and interior wall coating does not have anti-solarization function, so interior wall coating cannot be used when exterior coating.
Aerosol-type coating has easy to use, is easy to carry about with one, the advantages that long shelf-life, sprays air brushing etc. at the scene
It is widely applied.As the rapid development of sociaty and economy, it is organic to also proposed low volatility to aerosol-type coating products
Object（VOC）Discharge, the requirement without heavy metal etc..Water paint has obtained very in recent years as Environmentally friendly coatings
Big development, wherein having many advantages, such as that color is shallow, protects color, weather-proof, corrosion resistance using the water paint of water-based acrylic resin, extensively
It is general to apply in furniture, building, leather and fur products, the covering with paint of daily necessities and papermaking printing and dyeing, timber processing etc..But traditional gas
Mist type coating is there is also the gloss of film, water resistance, solvent resistance and stain resistance are poor, the mechanics such as hardness and impact strength
The performance also problem poor compared with solvent based product, therefore also need to study it.
Invention content
The present invention solves the technical problem of：For traditional aerial fog type water-based exterior wall paint paint film property, automatically cleaning
The bad problem of performance provides a kind of special wall covering of aerial fog type water-based exterior wall.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of special wall covering of aerial fog type water-based exterior wall, includes the raw material of following parts by weight：
200~300 parts of base-material water-base resin
80~100 parts of propellant
20~30 parts of function additive
The base-material water-base resin is made of the raw material of following parts by weight：50~80 parts of water-base resins, 50~60 parts of water, 8
~10 parts of absolute ethyl alcohols, 10~15 parts of butoxy ethanols；

The preparation process of the special wall covering of aerial fog type water-based exterior wall is：
（1）It is formed by raw material and weighs each component；
（2）By base-material water-base resin and function additive shearing dispersion, dispersion liquid is obtained, then gained dispersion liquid is added in inhalator jar,
Propellant is then added, then inhalator jar is sealed, storage storage is to get the special wall covering of aerial fog type water-based exterior wall.
The propellant is：F-11, difluoromethane, three chloro-tetrafluoroethanes and dimethyl ether are 1 in mass ratio：1：
1：1 mixes.
The water-base resin preparation process is：It is 1 in mass ratio by chitosan enzyme and chitosan solution：100~1：120 stir
Reaction is mixed, then through enzyme deactivation, chitosan liquid must be digested, then enzymolysis chitosan liquid quality 0.2~0.4 is added into enzymolysis chitosan liquid
The N of 0.1~0.2 times of Ludox again and Ludox quality, N '-methylene-bisacrylamides and Ludox quality 0.06~
0.08 times of sodium peroxydisulfate, heating stirring react 3~5h, obtain chitosan-Ludox base-material, then by gained chitosan-Ludox
Base-material and polyacrylic acid zinc resin are 3 in mass ratio：1~5：1 is stirred to get water-base resin.
The gelatin microcapsule preparation process is：It is 1 in mass ratio by linseed oil and gelatin solution：20~1：30 mixing point
It dissipates, obtains lotion, add the metabisulfite solution of quality of the emulsion 8~10%, after heating stirring mixing, cooling, and quality of the emulsion is added dropwise
8~10% formalin, then pH to 9.2~9.4 is adjusted, it is then cured, it filters, washing and drying obtain gelatin microcapsule.
The preservative is：It is any one in promise moral C15 sterilization antiseptics, Dao Weixier -75 or coating antiseptic N-369
Kind.
The self-control surfactant preparation process is：It counts in parts by weight, takes 170~180 parts successively（N- amidino groups）Ten
Dialkylacrylamides, 130~135 parts of polyethylene glycol phosphates, 3~4 parts of ferrocene, 10~15 parts of paracide, stirring are anti-
It answers, derives from control surface activating agent.
The sodium alginate dispersion liquid preparation process is：It is 1 in mass ratio by sodium alginate and water：10~1：15 mixing,
Add the sodium metaperiodate of 0.1~0.2 times of sodium alginate quality, after heating stirring reaction, add sodium alginate quality 1.1~
1.2 times of microcrystalline cellulose continues heating stirring reaction, discharges to get sodium alginate dispersion liquid.
The beneficial effects of the invention are as follows：
（1）The present invention is by adding sodium alginate dispersion liquid, and in preparation process, sodium alginate is acted in sodium periodate oxidation
Under, so that sodium alginate is changed into more aldehyde sodium alginates, during subsequent reactions, aldehyde radical in more aldehyde sodium alginates can be with
Aldol reaction occurs for activity hydroxy in microcrystalline cellulose, makes to form chemical bonding between sodium alginate and microcrystalline cellulose,
To improve the mechanical property for the paint film that more aldehyde sodium alginates are formed in exterior wall surface, furthermore, in use, in coating
Moisture can make the part calcium ion dissolution of exterior wall surface, and the presence of calcium ion may replace in the more aldehyde sodium alginates in part
Sodium ion, and chelate structure is formed, increase the binding force of alginic acid interchain, paint film stability is made to greatly improve, improves product capability
Paint film is set to be firmly attached on outer surface of wall while learning performance, and the absorption of free calcium ions is fixed, and metope can be effectively reduced
Accumulation of salt in the surface soil phenomenon；
（2）The present invention in base-material water-base resin by adding polyacrylic acid zinc resin, in use, polyacrylic acid zinc tree
Zinc ion in fat can be with Environmental Water（Rainwater, dew etc.）The soluble metal ion of middle dissolving（Sodium ion, potassium ion
Deng）Ion exchange occurs, to make the one end of polyacrylic resin with zinc ion become solvable, polypropylene segment acid resin is molten
It gradually falls off with rain drop erosion in water, the impurity for being attached to coating surface is enable to remove, play good automatically cleaning
Effect；
（3）The present invention is by adding the gelatin microcapsule containing linseed oil, and in use, paint film generates under external force to be split
Line, and the gelatin microcapsule of cracks ruptures after by mechanicals efforts, and the linseed oil wrapped up inside micro-capsule is enable to release
It puts, and linseed oil is drying oil, can be cured in cracks, realizes the selfreparing to crackle, avoids the further hair of paint film crackle
Deployment split, to make paint film service life effectively be extended.
