Abstract
The invention relates to a hydrophobic self-cleaning paint which comprises the following components in percentage by weight: 3 to 6 percent of water, 14 to 20 percent of 1.5-percent cellulose ether solution, 0.4 to 0.6 percent of dispersing agent, 0.3 to 0.5 percent of antifoaming agent, 0.2 to 0.4 percent of lignocellulose, 0.3 to 0.5 percent of polypropylene fibers, 6 to 10 percent of talcum powder, 40 to 46 percent of quartz sand and 24 to 35 percent of elastic emulsion. The paint not only has stain resistance, but also has the advantages of high performances of hydrophobicity, anti-permeability and the like and capability of obviously improving the phenomena of water whitening, dust attachment and the like of a wall, and prevents morbidness on the surface of a coating. The condition that the appearance of the coating of a building is easy to dirty and is whitened after raining is prevented; and the surface of the outer wall of the building can be guaranteed to be kept clean and gorgeous for a long time. A customer response effect is good.
Description
Technical field the present invention relates to a kind of coating, particularly a kind ofly prevents skin water suction, and the coating that contamination resistance is poor, belongs to chemistry painting industry technical field.
Background technology is in the construction process of building coating, and the quality of coating quality plays conclusive effect to appearance of film, and the whiting of chance water, the dust that film coated surface occurs such as adheres at problem and the coating quality to be had directly and contact.And now the stain resistant effect on market is not very desirable, for example publication number CN1912031 name be called " a kind of super resistant high antipollution composite elastic construction paint " although patent application in the coating that relates to there is certain anti-anti-stain characteristic energy, water-resistance property of coating index does not still reach desirable standard.Therefore research have efficient hydrophobic anti-stain characteristic can coating significant.
Summary of the invention the object of this invention is to provide a kind of hydrophobic chalking paint, and this coating not only has pollution resistance, also has the high performance such as hydrophobic, impervious, and the whiting of chance water, the dust that can significantly improve body of wall such as adheres at the advantage, prevents that morbid state from appearring in film coated surface.
A kind of hydrophobic chalking paint count by weight percentage into:
Water: 3-6%; 1.5% ether of cellulose solution: 14-20%; Dispersion agent: 0.4-0.6%; Defoamer: 0.3-0.5%; Lignocellulose: 0.2-0.4%; Polypropylene fibre: 0.3-0.5%; Talcum powder: 6-10%; Quartz sand: 40-46%; Elastic emulsion: 24-35%;
The elastic emulsion that the present invention uses is the anionic phenylethylene ethylene/propenoic acid ester copolymer without softening agent, and solids content is 56-58%, and minimum film-forming temperature is at-7 ℃.Can improve the flexibility of cement, and have good water-fast, alkaline-resisting and low temperature elasticity.
The Gonak that the ether of cellulose solution that the present invention uses is 1.5%, molecular weight is 55000.Have excellent water-retentivity, good temperature stability, improves putty application property, improves cohesive strength.
The lignocellulose length that the present invention uses is 300-400 μ m, and density is 0.8～1.3g/cm
3.Have excellent workability, anti-current pendant performance, improves the cohesive strength of material surface intensity He Yu basic unit, and can play good cracking resistance effect.
The polypropylene fibre that the present invention uses is reel off raw silk from cocoons production technique and surface-treated 100% polypropylene through special, and length is 3-4mm.Can improve the bond stress with cement material, the putty ultimate elongation rate that is mixed with fiber is improved, thereby greatly improve the anti-cracking performance of putty.In addition, this fiber can be easy to rapidly mix with putty, is monofilament state and is evenly distributed in system, forms a uniform three-dimensional netted unrest to support system.Thereby produce a kind of stiffening effect effectively, reach cracking resistance, impervious, shock resistance, freeze proof object.
The dispersion agent that the present invention uses is low molecular weight sodium polyacrylate dipersant, can significantly improve concentration and the stability thereof of fillers dispersed slurry, by this dispersion agent, can surround a layer charge on filler particles surface, make repulsion mutually between particle, thereby reach the effect of stable slurry.
The talcum powder that the present invention uses is 325 orders, and quartz sand is 200 orders, and coarse whiting is 400 orders, and the label of white cement is 425#.
Production technique of the present invention is: after weighing in the ratio of formula, be sequentially added into various materials under stirring at low speed, stir; B component: add dry powder blender to mix after white cement, coarse whiting are weighed according to the ratio of formula.
During use, in the ratio mixing and stirring of 1.5:1, just can carry out blade coating at the construction field (site).
Below embodiment, be one embodiment of the present of invention.
, by A, two kinds of components of B, being formed, its content is as follows:
A component: 3 parts of deionized waters; 18 part of 1.5% Gonak 41070; 0.5 part of dispersion agent 602N; 0.3 part of defoamer F111; 0.3 part of lignocellulose FD40; 0.3 part of polypropylene fibre EW-01; 8 parts of fineness 325 object talcum powder; 43.6 parts of fineness 200 object quartz sands; 26 parts of elastic emulsions 601.
B component: the white cement of 65 parts of 425#, 35 parts of fineness 400 object coarse whitings.
A and B are constructed with the part by weight mixing and stirring of 1.5:1.
Its indices of hydrophobic chalking paint of making according to the present invention all reaches GB/T9755-2009 about the requirement of exterior coating defined, and there is excellent hydrophobic, anti-stain characteristic, and sticking power is good, and anti-permeability performance is remarkable, can significantly improve the waterproof of body of wall, anti-stain characteristic energy.The appearance of film that prevents buildings easily whitens after dirty, rain, can guarantee the magnificent surface that can keep clean muchly, skin surface.Customer response is respond well.
