Abstract
The invention discloses a kind of freedom from cracking putty powder for exterior wall, it is mainly made up of the raw material of following weight parts: heavy calcium carbonate 600 700；Sierozem power 30 70；White cement 260 320；Hydroxypropyl methyl cellulose 3.5 5.5；Wood fibre 0.6 1.5.The freedom from cracking putty powder for exterior wall of the present invention, not only has extremely strong resistance to water and caking property, but also has the advantages such as high-low temperature resistant change, freedom from cracking, solve the problem that existing putty powder for exterior wall weatherability is poor.
Description
Technical field
Design building material of the present invention, particularly relates to a kind of have the putty powder for exterior wall that freedom from cracking is effective.
Background technology
Putty powder for exterior wall is with inorganic coagulation material as base-material, is equipped with binding material and other auxiliary agent retrofits form.
Its prominent feature is that bond strength is high, resistance to water, alkali resistance, has good workability.Existing putty powder for exterior wall is typically by plain boiled water
The raw material compositions such as mud, dry powder, sierozem power, rubber powder, wherein, rubber powder plays bond performance and the cohesive force improving material, reduces
The effect of the water-retaining property of the water imbibition of material and raising use process.The shortcoming of existing powder of lacquer putty for use on is: in morning and evening difference variation relatively
Easily chapping in the environment of great, even come off, weatherability is poor.
For the deficiency of existing putty powder for exterior wall, the applicant have developed a kind of preferable exterior wall putty of freedom from cracking effect
Powder, has solved the problems referred to above.
Summary of the invention
In view of this, the invention provides a kind of freedom from cracking putty powder for exterior wall, this putty powder for exterior wall not only adhesion strength is high,
Waterproof, but also there is the advantage of freedom from cracking, solve the problem that existing putty powder for exterior wall weatherability is poor.
The present invention solves the problems referred to above by techniques below means:
The invention provides a kind of freedom from cracking putty powder for exterior wall, it is mainly made up of the raw material of following weight parts: heavy carbon
Acid calcium powder 600-700；Sierozem power 30-70；White cement 260-320；Hydroxypropyl methyl cellulose 3.5-5.5；Wood fibre 0.6-
1.5。
Further, it is mainly made up of the raw material of following weight parts: heavy calcium carbonate 650；Sierozem power 50；White cement
300；Hydroxypropyl methyl cellulose 4.5；Wood fibre 1.
Further, the viscosity of described hydroxypropyl methyl cellulose is 8 ten thousand to 10 ten thousand mpas.
Further, it is possibly together with the pure iron powder of weight portion 3-5.
The putty powder for exterior wall of the present invention has the advantages that
1, the freedom from cracking putty powder for exterior wall of the present invention not only has extremely strong resistance to water and caking property, but also has resistance to height
The advantages such as low temperature change, freedom from cracking, solve the problem that existing putty powder for exterior wall weatherability is poor.
2, the freedom from cracking putty powder for exterior wall of the present invention, it is possibly together with the pure iron powder of weight portion 3-5, and pure iron is in nature
A few one of material that expands with cold and contracts with heat, after adding pure iron in putty powder for exterior wall, the coefficient of thermal expansion and contraction of powder of lacquer putty for use on reduces very
To vanishing so that powder of lacquer putty for use on will not chap because difference variation is big, further increases the weatherability of powder of lacquer putty for use on.It addition,
Pure iron also has the effect of absorption of electromagnetic radiation so that the powder of lacquer putty for use on of the present invention is suitable for decorating at the bigger environment of electromagnetic radiation,
On decoration skin near generating field, high-voltage line, telecomm base station.
Detailed description of the invention
Embodiment one standard type freedom from cracking putty powder for exterior wall
Standard type freedom from cracking putty powder for exterior wall in the present embodiment, it is mainly made up of the raw material of following weight parts: heavy
Paris white 650；Sierozem power 50；White cement 300；Hydroxypropyl methyl cellulose 4.5；Wood fibre 1.Preferably, heavy used
The grain fineness of Paris white is not less than 300 mesh, and as the main filler of powder of lacquer putty for use on, heavy calcium carbonate can be strengthened putty
The intensity of powder；White cement is the abbreviation of white portland cement, is to be added gypsum by white portland cement clinker, levigate makes
Hydraulic cementing materials, be typically characterised by and there is the highest whiteness, and adhesion strength is high, water resistance is good, it is preferred that this
In bright putty powder for exterior wall, the fineness particle diameter of white cement is not less than 300 mesh；Hydroxypropyl methyl cellulose be thickener, dispersant and
Stabilizer, all has good intermiscibility in water or organic solvent, and the water retention property of hydroxypropyl methyl cellulose makes powder of lacquer putty for use on exist
Will not chap because of dry too fast after smearing, enhance intensity after hardening, and the freedom from cracking effect of powder of lacquer putty for use on can be significantly improved,
Preferably, the viscosity of described HPMC is 8 ten thousand to 10 ten thousand mpas；Wood fibre can reduce expanding with heat and contract with cold of powder of lacquer putty for use on
Number, improves the freedom from cracking performance of powder of lacquer putty for use on, additionally adds wood fibre and may also function as heat insulation effect.
Embodiment two Anti-radiation type freedom from cracking putty powder for exterior wall
Anti-radiation type freedom from cracking putty powder for exterior wall in the present embodiment two be standard type freedom from cracking putty powder for exterior wall enter one
Walking modified, it is mainly made up of the raw material of following weight parts: heavy calcium carbonate 600；Sierozem power 30；White cement 320；Hydroxypropyl
Ylmethyl cellulose 5.5；Wood fibre 0.6；Pure iron powder 5.Preferably, the viscosity of described HPMC is 8 ten thousand to 10 ten thousand millipascal
Second；The grain fineness of described heavy calcium carbonate is not less than 300 mesh；The fineness particle diameter of white cement is not less than 300 mesh.Greasy at exterior wall
After adding pure iron in sub-powder, the coefficient of thermal expansion and contraction of powder of lacquer putty for use on reduces even vanishing so that powder of lacquer putty for use on will not become because of the temperature difference
Change big and chap, further increase the weatherability of powder of lacquer putty for use on.It addition, pure iron also has the effect of absorption of electromagnetic radiation so that
The powder of lacquer putty for use on of the present invention is suitable for decorating at the bigger environment of electromagnetic radiation, if decoration is near generating field, high-voltage line, telecomm base station
Skin on.
Putty powder for exterior wall in embodiment one and two, through Chongqing City Metering Quality Test Inst., sampling is tested, institute
Inspection project meets the requirement of " putty for exterior use " JG/157-2004 standard, qualified.
Its assay such as following table:
Experiment shows, the freedom from cracking putty powder for exterior wall of the present invention, not only has extremely strong resistance to water and caking property, but also
There is the advantages such as high-low temperature resistant change, freedom from cracking, solve the problem that existing putty powder for exterior wall weatherability is poor.
Finally illustrating, above example is only in order to illustrate technical scheme and unrestricted, although with reference to relatively
The present invention has been described in detail by good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent, and without deviating from objective and the scope of technical solution of the present invention, it all should be contained at this
In the middle of the right of invention.
