Abstract
Dumb light transparent dust-proof finish disclosed by the invention, it is prepared by organic silicon emulsion, polyurethane thickener, hydrophobically modified aqueous slkali swollen thickener, emulsifying agent, defoamer, bactericide, pH adjusting agent, Lauryl Alcohol ester, ethylene glycol and water.The invention also discloses the preparation method of the dumb light transparent dust-proof finish.The committed step of the present invention is that Lauryl Alcohol ester and ethylene glycol are fabricated to the milkiness suspension of 10 20 μm of particle diameter using emulsifying agent, these scattered droplets can be evenly distributed among paint film during coating application, in the drying process, the droplet on close surface can gradually protrude coating surface due to surface tension effects, the evaporation rate of these droplets is slower than water, therefore numerous pit can be left in coating surface after dried, so that coating surface obtains matte effect to light diffusing reflection.
Description
Technical field
The present invention relates to technical field of paint preparation, more particularly to a kind of dumb light transparent dust-proof finish and preparation method thereof
Background technology
Transparent dust-proof finish paint is a kind of widely used coating of building field, for protecting middle coating intermediate to be invaded from environment
Erosion, improve the weather-proof anti-pollution characteristic of building coating.Transparent dust-proof finish paint generally has the class of matte and glossy two, due to the dust-proof face of dumb light
Paint covers metope out-of-flatness defect, more fully the characteristic such as displaying middle coating intermediate color, finish application more dust-proof than light are more.
The dust-proof finish paint of traditional dumb light is coating surface is become coarse by adding glass micro mist, so as to obtain diffusing reflection
Matte effect, but many defects of this method, glass micro mist can reduce the transparency of dust-proof finish paint first, influence middle level
Painting color shows, and construction became uneven is also easy to cause to grow dim；Secondly, glass micro mist easily precipitates, flocculated, once occur
Such case paint film may whiten, so shelf life of products is extremely short；Easily floating is sucked other glass micro mist by human body, to life
Production worker has larger threat, there is certain environment harmfulness.These defects limit the popularization of product.
Although also there is the dust-proof finish paint technology of other dumb lights in recent years, the dumb light emulsion matched somebody with somebody for example with emulsion particle diameter pole, can
To overcome above-mentioned most of defect, but with high costs, emulsion gloss is not sufficiently stable, and coatings enterprises formula design space is limited
Deng defect is also fairly obvious.
The content of the invention
The present invention to be solved one of technical problem and be that the above-mentioned technology present in the dust-proof finish paint of existing dumb light is asked
Inscribe and a kind of dumb light transparent dust-proof finish is provided.The dumb light transparent dust-proof finish need not add common glass micro mist or make
With the dumb light emulsion specially matched somebody with somebody, you can obtain matte surface effect, can effectively reduce formulation cost, and improve formulation stability.
The present invention to be solved the two of the technical problem preparation method for being to provide above-mentioned dumb light transparent dust-proof finish.
As the dumb light transparent dust-proof finish of first aspect present invention, it is prepared by the raw material of following parts by weight：
In a preferred embodiment of the invention, the organic silicon emulsion is selected from Ahmedabad richness RS-996AD, sunrise TD-
661B, Bao Lijia BLJ-KD96, one kind in ten thousand magnificent Archsol8087 or both any mixing.
In a preferred embodiment of the invention, the polyurethane thickener is selected from Tao Shi RM-8W, RM-2020, Wan Hua
One kind or both any mixing in U601, U505.
In a preferred embodiment of the invention, the hydrophobically modified aqueous slkali swollen thickener is selected from Tao Shi TT-
935th, one kind in ten thousand magnificent A406 or both any mixing.
In a preferred embodiment of the invention, the emulsifying agent is selected from Tao Shi BD-109, Ke Laien LCN-407, sieve
One kind or both any mixing in the CO-630 of ground Asia.
In a preferred embodiment of the invention, the defoamer in Nuo Pu sections NXZ, Bi Ke LPD23159 one
Kind or both any mixing.
In a preferred embodiment of the invention, the bactericide in Sol DB20, Tao Shi Rocima562 one
Kind or both any mixing.
In a preferred embodiment of the invention, the pH adjusting agent in Tao Shi AMP-95, Bi Ke BS168 one
Kind or both any mixing.
As the preparation method of the dumb light transparent dust-proof finish of second aspect of the present invention, comprise the following steps：
(1) a part of water, ethylene glycol, Lauryl Alcohol ester, emulsifying agent, defoamer, bactericide are mixed, and stirred with dispersion machine
10-12min is mixed, is fabricated to milkiness suspension of the size droplet diameter at 10-20 μm；
(2) organic silicon emulsion that formula ratio is added in milkiness suspension prepared by step (1) stirs；
(3) polyurethane thickener, hydrophobically-modified alkali swollen thickener, pH adjusting agent, the water for adding formula ratio adjust viscosity,
65-75KU and pH value are 7~9 acquisition dumb light transparent dust-proof finishes.
The committed step of the present invention is that Lauryl Alcohol ester and ethylene glycol are fabricated to the breast of 10-20 μm of particle diameter using emulsifying agent
Turbid suspension, these scattered droplets can be evenly distributed among paint film during coating application, in the drying process, lean on
For the droplet of near surface because surface tension effects can gradually protrude coating surface, the evaporation rate of these droplets is slower than water,
Therefore numerous pit can be left in coating surface after dried, so that coating surface obtains dumb light effect to light diffusing reflection
Fruit.Its process is as shown in Figure 1 to Figure 3.
Brief description of the drawings
Fig. 1 is view when dumb light transparent dust-proof finish of the present invention construction is completed.
Fig. 2 is the paint film view in dumb light transparent dust-proof finish drying process of the present invention.
Fig. 3 is the paint film view after dumb light transparent dust-proof finish drying process of the present invention.
