Abstract
The invention relates to technical field of coatings, and particularly relates to a preparation method of an exterior wall coating of magnesium oxychloride cement. The method comprises the following steps: stirring and mixing caustic dolomite dust, coal ashes or silica fume, straws or sawdust and a sand mixture evenly at the mass ratio of 100 to (5-20) to (10-50) to (10-70), so as to form a backing material; adding 20-25 parts by weight of magnesium chloride water to the backing material; and stirring evenly to form the coating coated on an exterior wall, wherein the mass ratio of the caustic dolomite dust to the magnesium chloride water is 1 to (1-2.1).The exterior wall coating disclosed by the invention is good in fireproof performance, good in cold tolerance, simple in process, convenient to construct and operate, low in cost, and very suitable for popularization and application in the northwest region, and also has a certain heat preservation 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 and a kind of be coated on external wall of house based on magnesia oxychloride cement exterior coating and can form better outer wall coating.
The preparation method of this magnesia oxychloride cement exterior coating, comprises the steps:
A, be that 100:5 ~ 20:10 ~ 50:10 ~ 70 stirring and evenly mixing forms bed material by caustic dolomite powder, flyash or silicon ash, stalk or sawdust, sandy soil mixture according to mass ratio;
B, in described bed material, add the magnesium chloride brine that massfraction is 20 ~ 25, stir the coating being formed and be coated on exterior wall; Wherein, the mass ratio of described caustic dolomite powder and described magnesium chloride brine is 1:1 ~ 2.1.
Preferably, the mass ratio of described caustic dolomite powder, flyash or silicon ash, stalk or sawdust, sandy soil mixture, magnesium chloride brine also provides more preferred proportionlity, is 100:5 ~ 20:20 ~ 45:10 ~ 65:120 ~ 175.
Further, the length of described stalk or sawdust is less than 0.5cm.
Further, in described sandy soil mixture, husky is 1 ~ 5:1 ~ 8 with the mass ratio of soil.
The present invention also provides this cement exterior coating, the caustic dolomite powder of 100:5 ~ 20:10 ~ 50:10 ~ 70:100 ~ 210, flyash or silicon ash, stalk or sawdust, sandy soil mixture and magnesium chloride brine; The massfraction of described magnesium chloride brine is 20 ~ 25.
Further, the length of described stalk or sawdust is less than 0.5cm.
Further, in described sandy soil mixture, husky is 1 ~ 5:1 ~ 8 with the mass ratio of soil.
Further, the thickness of described coating is 5 ~ 20mm.
Beneficial effect: the present invention utilizes magnesia oxychloride cement 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 be the embodiment of the present invention 1 based on magnesia oxychloride cement exterior coating Making programme figure.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is elaborated.
The present invention utilizes caustic dolomite powder, sand, flyash or silicon ash, soil, straw powder or sawdust and magnesium chloride solution mix evenly, is coated in exterior wall surface, forms outer wall coating material.
Embodiment 1
The present embodiment comprise various ingredients based on magnesia oxychloride cement exterior coating, often kind of component adds mixing according to mass ratio, and the step of this magnesia oxychloride cement exterior coating comprises the steps:
Shown in A, composition graphs 1,100 parts of caustic dolomite powder, the flyash of 5 parts, 20 parts of stalks, 10 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 1:1 mixes by sand and soil according to mass ratio.
B, in described bed material, add 120 parts, massfraction is the magnesium chloride brine 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 8MPa.
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 flyash of 20 parts, 45 parts of stalks, 65 parts, sandy soil mixtures are formed bed material by stirring and evenly mixing, adds 175 parts, massfraction is 20 magnesium chloride brines, again mix, obtain coating.Other steps are with reference to described in embodiment 1.
Wherein, sandy soil mixture by sand and soil in mass ratio for 5:8 mixes; Certainly, in other embodiments, stalk can also adopt sawdust to replace, and described flyash can also adopt silicon ash to replace.Control described caustic dolomite powder, flyash or silicon ash, stalk or sawdust, sandy soil mixture, magnesium chloride brine mass ratio be 100:5 ~ 20:20 ~ 45:10 ~ 65:120 ~ 175 scope Nei Gengjia.
