Abstract
The invention relates to the technical field of coatings, in particular to a preparation method of a magnesium oxysulfate cement coating for exterior walls. The method comprises steps as follows: evenly mixing caustic dolomite powder, an admixture, straw or sawdust as well as a sand and soil mixture in the mass ratio of 100:(0.1-1.5):(10-60):(15-80) to form a base material; adding a magnesium sulfate aqueous solution with the Baume degree ranging from 20 to 30 to the base material, and evenly mixing the mixture to form the coating for coating the exterior walls, wherein the mass ratio of the caustic dolomite powder to the magnesium sulfate aqueous solution is in a range of 1:(1-2). The coating for the exterior walls is good in fireproof performance, good in cold resistance, simple in process, convenient to construct and operate, low in cost and quite suitable for popularization and application in northwest regions and has a certain thermal insulation effect.
Description
Technical field
The present invention relates to technical field of coatings, refer in particular to a kind of exterior coating and preparation method thereof.
Background technology
Existing outer wall coating material and technology more, but produced problem is also more, such as play the problem such as drum, cracking, in flakes stripping comparatively serious, once there are the problems referred to above, remove maintenance maintenance again, construction is difficulty comparatively, and program is comparatively complicated, also a large amount of wasting manpower and material resources's financial resources simultaneously, therefore promote comparatively difficulty in vast farming and pastoral area.
Along with the needs of new countryside construction, current while giving priority to rural economy, improving peasants and herdsmen's living conditions is also the problem that can not be ignored, and especially in the Northwest, its natural condition are comparatively severe, have exigence to the insulation in house.But, be also test to the requirement of coating property in the presence of a harsh environment, develop and a kind ofly there is insulation effect and stable performance, exterior coating with low cost are extremely necessary.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of cement exterior coating and being coated on external wall of house and can forming better outer wall coating.
The preparation method of this magnesium oxysulfide concrete exterior coating, comprises the steps:
A, be that 100:0.1 ~ 1.5:10 ~ 60:15 ~ 80 stirring and evenly mixing forms bed material by caustic dolomite powder, admixture, stalk or sawdust, sandy soil mixture according to mass ratio;
B, in described bed material, add the magnesium sulfate solution that degree Beaume is 20 ~ 30, stir the coating being formed and be coated on exterior wall; Wherein, the mass ratio of described caustic dolomite powder and described magnesium sulfate solution is 1:1 ~ 2.
Preferably, described caustic dolomite powder, admixture, stalk or sawdust, sandy soil mixture, magnesium sulfate solution mass ratio are that the implementation result of 100:0.1 ~ 1:20 ~ 50:15 ~ 70:125 ~ 180 is better.
Further, the length of described stalk or sawdust is less than 0.5cm.
Further, in described sandy soil mixture, husky is 5 ~ 25:10 ~ 45 with the mass ratio of soil.
Further, described admixture is phosphoric acid salt.
The present invention also provides a kind of magnesium oxysulfide concrete exterior coating, and it comprises caustic dolomite powder that mass ratio is 100:0.1 ~ 1.5:10 ~ 60:15 ~ 80:100 ~ 200, admixture, stalk or sawdust, sandy soil mixture and magnesium sulfate solution; The degree Beaume of described magnesium sulfate solution is 20 ~ 30.
Further, the length of described stalk or sawdust is less than 0.5cm.
Further, in described sandy soil mixture, husky is 5 ~ 25:10 ~ 45 with the mass ratio of soil.
Further, described admixture is phosphoric acid salt.
Further, the thickness of described coating is 5 ~ 20mm.
Beneficial effect: the present invention utilizes magnesium oxysulfide concrete as gelling material, mixing caustic dolomite powder and common agricultural waste are as sandy soil, stalk etc., solve the house outer wall coating problem of the Northwest peasants and herdsmen, reach specious with it, fire resistance is good, winter hardiness is good, also has the object of certain heat insulation effect.Present invention process is simple, and constructing operation is convenient; With low cost, be highly suitable for the Northwest and apply.
Accompanying drawing explanation
Fig. 1 is the magnesium oxysulfide concrete exterior coating Making programme figure of the embodiment of the present invention 1.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is elaborated.
The present invention utilizes causticity caustic dolomite powder, sand, admixture, soil, straw powder or sawdust and Adlerika mix evenly, is coated in exterior wall surface, forms outer wall coating material.
Embodiment 1
The magnesium oxysulfide concrete exterior coating of the present embodiment comprises various ingredients, and often kind of component adds mixing according to mass ratio, and the step of this magnesium oxysulfide concrete exterior coating comprises the steps:
Shown in C, composition graphs 1,100 parts of caustic dolomite powder, the admixture of 0.1 part, 20 parts of stalks, 15 parts, sandy soil mixtures are pressed stirring and evenly mixing and formed bed material.Wherein, the length of stalk is crushed to and is less than 0.5cm; Sandy soil mixture is that 5:10 mixes by sand and soil according to mass ratio.Admixture is ammonium phosphate.
D, in described bed material, add 125 parts, degree Beaume is the magnesium sulfate solution of 23, forms the coating be coated on exterior wall after again stirring.
The coating material obtained by the present embodiment is at exterior wall surface, and coat-thickness 5mm, maintenance for some time, coating just can stick to exterior wall surface preferably after moisture evaporation is dry, formed stable coatings.Wherein, coat-thickness need acquire a certain degree and could obtain good stability, and general thickness is 5 ~ 20mm.This coating can play certain heat insulation effect, and fire resistance is good, does not come off simultaneously, do not ftracture, do not peel off in flakes, and strength of coating reaches more than 4MPa.
Embodiment two:
The proportionlity that what the present embodiment was different from embodiment 1 are between component,
The present embodiment is after 100 parts of caustic dolomite powder, the admixture of 1 part, 50 parts of stalks, 70 parts, sandy soil mixtures are formed bed material by stirring and evenly mixing, adds 185 parts, degree Beaume is 27 magnesium sulfate solutions, again mix, obtain coating.Other steps are with reference to described in embodiment 1.
