Abstract
The invention discloses a kind of no flatting silica transparent suboptical water-based exterior wall finishes and preparation method thereof.The exterior wall finish includes water, antifreezing agent, HBR250 hydroxyethyl cellulose, KW bentonite, DP-530 acrylic emulsion, defoaming agent, coalescing agent, TT-935 alkali swollen thickener and fungicide.The preparation method comprises the following steps: sequentially adding water, fungicide, HBR250 hydroxyethyl cellulose, pH adjusting agent in production equipment, first time dispersion is carried out；It reduces mixing speed and sequentially adds other raw materials, carry out second and disperse.The present invention uses three kinds of specific cellulose, bentonite and acrylic emulsions, and the compatibility difference being utilized between three's polymer achievees the purpose that controllable abatement film coated surface glossiness；Simplify production technology and eliminates the carbon emission that the higher flatting silica high speed dispersion process of energy consumption shortens production time, material loss and production process.
Description
Technical field
The present invention relates to a kind of, and two kinds of the utilization without flatting silica has special biocompatible acrylic's lotion and cellulose to reach
To the aqueous finish and preparation method thereof of extinction effect, belong to building material technical field.
Background technique
Water-in-water multicolor coating and lacquer on external wall using more and more, in building external paint yield
The specific gravity accounted for also will be more than 50%.Since the water resistance of water-in-water multicolor coating is poor, lacquer is because rough surface porosity is big
Stain resistance is poor, requires to brush transparent finish and be protected to reach corresponding requirements of the national standard.For product at
95% or more user of this and environmental-protecting performance selects the transparent finish of water soluble acrylic acid, for avoiding reflective dazzling and reduction from applying
Fill the transparent finish of water soluble acrylic acid that surface irregularity sense user generally selects matt effect.
Currently, mature matt water soluble acrylic acid translucent cover topcoat formulation technology is essentially all to be disappeared with addition silica
Light powder achievees the purpose that delustring.Since the water imbibition of silica flatting silica is higher, while in order to make silica flatting silica
It is evenly dispersed, prevent precipitating must be added to the hydrophilic compositions such as dispersing agent, anti-settling agent and thickener into formula.Contain in formula
The water-whitening resistance for having these hydroaropic substances that can enable the transparent finish of matt water soluble acrylic acid declines, aqueous in rainy day matt
Translucent cover top-coat paint film chance rainwater whitens and influences the appearance color and texture of water-in-water multicolor coating and lacquer, to influence to build
The decorative effect of wall face.
Summary of the invention
The technical problems to be solved by the present invention are: providing one kind for water-in-water multicolor coating, lacquer and needing to apply
Fill the transparent finish of matt water soluble acrylic acid of matt finishing varnish.
To solve the above-mentioned problems, the present invention provides a kind of no flatting silica transparent suboptical water-based exterior wall finishes, special
Sign is, including following component by weight percentage:
Preferably, the antifreezing agent uses polyalcohol.
It is highly preferred that the antifreezing agent is dihydric alcohol.
Preferably, the fungicide uses isothiazolinone biocide agent.
Preferably, the defoaming agent uses mineral oil type antifoaming agent.
Preferably, the coalescing agent uses alcohol ester 12.
Preferably, the DP-530 acrylic emulsion is film forming matter, is the saturating of the limited department's production of dupp benefit chemical science and technology
The bright dedicated acrylic emulsion of finish.
Preferably, the HBR250 hydroxyethyl cellulose is purchased from U.S. Ya Kualong company.
The present invention also provides a kind of preparation method of above-mentioned no flatting silica transparent suboptical water-based exterior wall finish, features
It is, water, fungicide, HBR250 hydroxyethyl cellulose, pH adjusting agent is sequentially added in production equipment, divide for the first time
It dissipates；It reduces mixing speed and sequentially adds coalescing agent, DP-530 acrylic emulsion, defoaming agent, TT-935 alkali swollen thickener,
Second is carried out to disperse.
Preferably, the revolving speed of the first time dispersion is 1000-2000rpm, jitter time 15min；Second of dispersion
Time be 20min.
The present invention replaces the silica flatting silica in conventional formulation to match using a small amount of cellulose of addition and bentonite
Hydroaropic substance in side, which significantly reduces to reach, significantly reduces the degree raising water-whitening resistance that matt finishing varnish meets water.
The present invention uses three kinds of specific cellulose, bentonite and acrylic emulsions, is utilized between three's polymer
Compatibility difference achievees the purpose that controllable abatement film coated surface glossiness；Simplify production technology and eliminates the higher delustring of energy consumption
Powder high speed dispersion process shortens the carbon emission of production time, material loss and production process.Meanwhile the present invention is not due to using
Flatting silica, dispersing agent and part defoaming agent are so cost is also declined.
Specific embodiment
In order to make the present invention more obvious and understandable, it is hereby described in detail below with preferred embodiment.
Antifreezing agent in embodiment 1-2 uses dihydric alcohol；Fungicide uses isothiazolinone biocide agent；Defoaming agent uses
Mineral oil type antifoaming agent；Coalescing agent uses alcohol ester 12；DP-530 acrylic emulsion is film forming matter, is dupp benefit chemical industry section
The dedicated acrylic emulsion of transparent finish of the limited department's production of skill；HBR250 hydroxyethyl cellulose is purchased from U.S. Ya Kualong company.
