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 are more, but produced problem is the most more, such as play drum, open
Split, in flakes the problem such as stripping more serious, the problems referred to above once occur, then remove maintenance maintenance, construction is more
Difficulty, program is complex, the most a large amount of wasting manpower and material resources's financial resources, therefore promotes in vast farming and pastoral area
More difficulty.
Along with the needs of new countryside construction, currently while giving priority to rural economy, improve agriculture and animal husbandry local-style dwelling houses
Living condition is also the problem that can not be ignored, and especially in the Northwest, its natural conditions are more severe, to house
Insulation have exigence.But, the requirement to coating property is also test in the presence of a harsh environment, exploitation
A kind of have insulation effect and stable performance, exterior coating with low cost is extremely necessary.
Summary of the invention
For overcoming the deficiencies in the prior art, the present invention provides a kind of cement exterior coating to be coated on external wall of house energy
Form preferable outer wall coating.
The preparation method of this magnesia oxychloride cement exterior coating, comprises the steps:
A, light burnt powder, flyash or silicon is grey, straw or sawdust, sandy soil mixture are 100 according to mass ratio:
5～20:10～70:20～110 stirring and evenly mixings form bed material；
B, toward described bed material adds the magnesium chloride brine that mass fraction is 20～25%, stir formation
The coating being coated on exterior wall；Wherein, described light burnt powder with the mass ratio of described magnesium chloride brine is
1:1～2.6.
Preferably, described light burnt powder, flyash or silicon ash, straw or sawdust, sandy soil mixture, magnesium chloride
The mass ratio of aqueous solution also provides for the proportionate relationship being more highly preferred to, and is 100:8～18:30～60:55～70:
135～90.
Further, the length of described straw or sawdust is less than 0.5cm.
Further, in described sandy soil mixture, husky and soil mass ratio is 4～5:2～10.
The present invention also provides for this cement exterior coating, 100:5's～20:10～70:20～110:100～260
Light burnt powder, flyash or silicon ash, straw or sawdust, sandy soil mixture and magnesium chloride brine；Described chlorination
The mass fraction of magnesium aqueous solution is 20～25%.
Further, the length of described straw or sawdust is less than 0.5cm.
Further, in described sandy soil mixture, husky and soil mass ratio is 4～5:2～10.
Further, the thickness of described coating is 5～20mm.
Beneficial effect: the present invention utilize magnesia oxychloride cement as Binder Materials, mixing light burnt powder and common
Agricultural residue such as sandy soil, straw etc., solve the house outer wall coating problem of the Northwest peasants and herdsmen, reach with it
To specious, fire protecting performance is good, and tolerance to cold is good, also has the purpose of certain heat insulation effect.The present invention
Technique is simple, and constructing operation is convenient；With low cost, it is highly suitable for the Northwest's popularization and application.
Accompanying drawing explanation
Fig. 1 is the magnesia oxychloride cement exterior coating Making programme figure of the embodiment of the present invention 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is elaborated.
Magnesite calcines title " light-burned " at 750-1100 DEG C, and its product claims light-burning magnesium powder, referred to as light burnt powder.
The present invention is to utilize light burnt powder, sand, flyash or silicon ash, soil, powder of straw or sawdust and magnesium chloride solution
Mix is uniform, is coated in exterior wall surface, forms outer wall coating material.
Embodiment 1
The magnesia oxychloride cement exterior coating of the present embodiment includes that various ingredients, every kind of component add according to mass ratio
Entering mixing, the step of this magnesia oxychloride cement exterior coating comprises the steps:
A, combine shown in Fig. 1, by 100 parts of light burnt powders, the flyash of 8 parts, 60 parts of straws, sandy soil mixing
Thing 55 parts is pressed stirring and evenly mixing and is formed bed material.Wherein, the length of straw is crushed to less than 0.5cm；Sandy soil mix
Thing is to be that 4.5:1 mixes by sand and soil according to mass ratio.
B, toward described bed material adds 180 parts, mass fraction be the magnesium chloride brine of 23%, again stir
Mix and uniformly form the coating being coated on exterior wall afterwards.
The coating material that the present embodiment obtains was treated in exterior wall surface, coating layer thickness 5mm, maintenance a period of time
After moisture evaporation is dry, coating just can preferably stick to exterior wall surface, forms stable coatings.Wherein, coating
Thickness need to reach to a certain degree could obtain preferable stability, and general thickness is 5～20mm.This coating can rise
To certain heat insulation effect, fire protecting performance is good, does not falls off simultaneously, does not ftractures, peels off the most in flakes, and coating is strong
Degree reaches more than 8MPa.
Embodiment two:
The proportionate relationship that what the present embodiment was different from embodiment 1 are between component,
The present embodiment is by 100 parts of light burnt powders, the flyash of 18 parts, 30 parts of straws, sandy soil mixture 70
Part press stirring and evenly mixing formation bed material after, add 130 parts, mass fraction be 20% magnesium chloride brine, again
Mix homogeneously, it is thus achieved that coating.Other steps are with reference to described in embodiment 1.
Wherein, sandy soil mixture is mixed for 2:5 in mass ratio by sand and soil；Certainly, real at other
Executing in example, straw can also use sawdust to replace, and described flyash can also use silicon ash to replace.Control
Make described light burnt powder, flyash or silicon ash, straw or sawdust, sandy soil mixture, magnesium chloride brine quality
Than in the range of 100:8～18:30～60:55～70:130～180 more preferably.
The coating material obtained by the present embodiment is in exterior wall surface, coating layer thickness 20mm, maintenance a period of time
After moisture evaporation is dry, coating just can preferably stick to exterior wall surface, forms stable coatings, and intensity is at 4MPa
Above.
The invention reside in and utilize discarded straw or sawdust, do rural house outer wall coating material, to reach
Twice laid, simultaneously can also be cost-effective, and coating result is preferable, and constructing operation is simple, works it out room
Room exterior wall is beautiful attractive in appearance, good weatherability, also has the features such as certain heat insulation effect.
