A kind of exterior wall putty
Technical field
The present invention relates to a kind of coating putty of smearing exterior wall, particularly a kind of coating putty that can prevent to spread upon coating cracking on cement wall and the concrete wall surface, the accumulation of salt in the surface soil, contamination, variable color, come off.
Background technology
Common meeting daub on the building masonry wall basal plane, the purpose of smearing exterior coating is a defective of covering up the body of wall basal plane, and body of wall is played the certain protection effect, and the protection reinforcing bar is difficult for corrosion, and the protection concrete is difficult for carbonization, chlorination, is not subjected to the infringement of mould algae.But, therefore before swabbing, all need smear one deck putty earlier because the building masonry wall basal plane all has various defectives.And ubiquity cracking, the accumulation of salt in the surface soil, the variable color in use of present exterior coating, phenomenon such as stain, come off, trace it to its cause, mainly be present employed exterior wall putty have loose shaky, come off easily, what have does not have elasticity, not water-fast, make the exterior coating cracking easily, the accumulation of salt in the surface soil, stain variable color, even come off, thereby the work-ing life of having reduced buildings, and influence the overall appearance of buildings.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of putty that is used for cement wall and concrete wall surface, this putty strong adhesion, fillibility is good, can prevent the exterior coating accumulation of salt in the surface soil, variable color, stain, come off, ftracture, can exempt the used alkali resistant priming paint of conventional outer wall paint, thereby save finish paint 15-20%, and good waterproof effect is arranged.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of exterior wall putty is characterized in that this exterior wall putty mainly is made up of following materials in weight percentage: soft water 10-13%, methylcellulose gum 0.2-0.3%, lithium minerals thickening material 0.1-0.2%, poly carboxylic acid amine salt 0.3-0.5%, the silicon third latex 10-15%, wax emulsion 0.3-0.5%, high sticking body properties-correcting agent 0.1-0.2%, ethylene glycol 0.5-1%, 12 carbon esters alcohol 0.5-0.7%, Zinc Stearate 1-5%, defoamer 0.1-0.3%, coarse whiting 200 order 30-40%, talcum powder 400 order 25-35%.
The sticking body properties-correcting agent of height of the present invention is 2-amido-2-methyl isophthalic acid-propyl alcohol, and model is AMP-95.
Defoamer of the present invention is the mixture of organosilicon and mineral oil.
Exterior wall putty of the present invention also includes 0.1-0.2% sanitas isothiazolinone, does not contain formaldehyde in this sanitas.
Preferred molecular weight of the present invention is 6000 methylcellulose gum.
The poly carboxylic acid amine salt model that the present invention adopts is SN-Dispersant5027, and the poly carboxylic acid amine salt of this model can be buied on market, and this poly carboxylic acid amine salt is the amine volatilization when putty is dry, forms water-insoluble substance.
The present invention can produce according to common process, as feeding intake in order, stirs while feeding intake, and waits to be uniformly dispersed and can shut down discharging at once.
The invention has the beneficial effects as follows: the present invention adopts that seepage force is strong, water-tolerant, silicon third emulsion paint flexible, particulate footpath with alkali resistance are done filmogen, adopt the lithium minerals thickening material, use volatilizable dispersion agent poly carboxylic acid amine salt dispersed color, dispersion agent finally volatilizees away in putty, has reduced the negative interaction of dispersion agent to putty water tolerance and water resistance; Form hydrophobic systems in order to make the putty film forming solidify the back, the present invention has added wax emulsion and organic amine properties-correcting agent 2-amido-2-methyl isophthalic acid-propyl alcohol, the wax emulsion has very strong water resistance, slight glue can take place with filmogen and connect reaction in organic amine 2-amido-2-methyl isophthalic acid-propyl alcohol, improve putty and become film toughness, sticking power and anti-cracking performance, thereby can prevent the exterior coating accumulation of salt in the surface soil, variable color, stain, come off, and can prevent the cracking of cement wall and concrete wall surface, prolong the life-span of buildings, helped strengthening the overall appearance of buildings.
Embodiment
The present invention is further described below in conjunction with embodiment.
