50 parts, 10-15 parts of moisture proof expansive Pearle, 5-10 parts of adhesive, 4-8 parts of hydrophobic type polymer dispersion powder, three ethoxy of methyl
0.5-1 parts of base silane, 0.5-1 parts of organo montmorillonite, 0.3-0.5 parts of water-retaining admixture and 0.1-0.15 parts of anticracking fiber.It is logical
It crosses the heat preserving aggregate that hydrophobic type is added and hydrophober greatly promotes moisture-proof, the water-fast effect of product, the adhesion strength of material
Height, resistance to compression, cracking resistance are excellent.
But with the development of architectural decoration, people pursue the high-performance of building decoration materials, environmental protection it is same
When, the trend of the times that efficiently construction is also industry development is carried out by the mechanical equipment of modernization, such as efficiently, environmental protection, low labor
The spraying application of fatigue resistance.And contain the biggish quartz sand aggregate of density in above-mentioned compound insulating material, it is easy when adding dilutional hyponatremia
It is not ideal enough to mix and stir rear stability for Precipitation；The dispersible cream of adhesive, organo montmorillonite, water-retaining admixture and hydrophobic type
Rubber powder is big to thermal insulation material viscosity influence, adds that the viscosity of thermal insulation material after water mixing is high, mobility is poor, it is difficult to be sprayed
Construction.Due to the presence of these factors, above-mentioned compound insulating material can only pass through conventional inefficient, large labor intensity batch of side of scraping
Formula construction, can not adapt to the spraying application of modernization.
Therefore, how to research and develop a kind of heat preservation and soundproof effect it is good and be suitable for machine spray work high-performance gypsum base heat preservation sand
Slurry is urgent problem to be solved in the industry.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of high-strength gypsum-base sound-insulating machine spray
Mortar, with good effect of heat insulation, waterproofness is good, the advantage of work is sprayed suitable for high efficiency machine.
To achieve the above object, the present invention provides following technical solutions：
A kind of high-strength gypsum-base sound-insulating Machine-blasting mortar, including following component by weight,
White high strength gypsum 800-850 parts
30-60 parts of hollow glass microbead
Light vitreous microballon 30-60 parts
60-120 parts of hydrophobic type polymer dispersion powder
3-5 parts of cellulose ether
2-10 parts of bentonite
4.0-5.5 parts of calcium sulphate retarder
900-1000 parts of water.
By using above-mentioned technical proposal, at least have the following advantages that：1, the Machine-blasting mortar mobility of above-mentioned substance proportion
Good, good stability, is less prone to layering, bleed phenomenon, is suitable for carrying out spraying application with machine spraying equipment, with high construction efficiency,
The advantage that fugitive dust is few, labor intensity is low.2, it using white high strength gypsum as coagulated material, is mixed with hydrophobic type polymer dispersion powder
It uses, so that the adhesive fastness of Machine-blasting mortar is high, can be firmly attached to after spraying in construction base, and be not likely to produce back after solidifying
Contracting, the problems such as being less prone to cracking, hole, be bubbled；Meanwhile high strength gypsum used in other types gypsum and the present invention is in pressure resistance
Degree, setting time etc. there are performance difference, do not have an applicability, thus cannot with common semi-hydrated gypsum, desulfurized gypsum,
Ardealite etc. substitutes high strength gypsum of the invention.3, use hollow glass bead and light vitreous microballon as heat preserving and insulating material, energy
Assign Machine-blasting mortar excellent heat insulating effect, and soundproof effect is good.And two kinds of materials itself have splendid stream
Dynamic property, when mixing mortar, stir at low speed and can be uniformly dispersed, and machine is also not easy precipitating isolation during spraying work.4, hollow glass is micro-
The equal vitrifying in the surface of pearl and light vitreous microballon, consistency is higher, compared to the prior art（CN106316320A）Middle use
Expanded perlite, also there is good hydrophobicity without carrying out hydrophobic processing, and compared to expanded perlite, hollow glass
Microballon and light vitreous microballon are not easy because stirring collision is broken during mixing mortar, reduce because mixing it is improper caused by
The decline of mortar thermal and insulating performance.5, the cellulose ether of above-mentioned volume can increase the water-retaining property of Machine-blasting mortar, have to improve and protect
The effect of adiabator workability.6, hydrophobic type polymer dispersion powder can form polymer in Machine-blasting mortar solidification process
Hollow glass microbead and light vitreous microballon can be coated, be improved by film, the space multistory network structure that molecule long-chain is formed
While adhesion strength, reduction shrinking percentage, so that mortar has good dispersion stabilization, it is not easy layering or bleed,
Furthermore hydrophobic type dispersed latex powder also has the function of adjusting consistency of mortar and water-retaining property.7, bentonite can select Na-bentonite
The bentonite of soil, lithium bentonite or calcium-base bentonite, above-mentioned volume has good pulping, so that mortar is full flat
It is sliding；Meanwhile bentonite cooperation cellulose ether uses, and can cooperate with the application property for improving mortar, so that mortar is not in spraying pipeline
Inside stick together, it is easy for construction；In addition, bentonitic incorporation also has the function of improving mortar bonding fastness, the height of itself
Adsorptivity enables bentonite permanently to adsorb the radiological material in fixed wall, has the function of radiation protection.
Further, the flexural strength of the white high strength gypsum is greater than 5MPa.
By using above-mentioned technical proposal, the inadequate, compactness by intensity after the low gypsum preparation mortar construction of flexural strength
It is bad, thus the high strength gypsum with flexural strength greater than 5MPa is advisable.
Further, the real density of the hollow glass microbead is 0.2-0.6g/cm3。
By using above-mentioned technical proposal, the density of hollow glass microbead is higher than 0.6g/cm3When, it will increase sand after construction
The density of pulp layer reduces its insulation, soundproof effect；And real density is lower than 0.2g/cm3Hollow glass microbead be not only easy
It is crushed in whipping process, influences its and play heat insulating effect, and since its density is low, be easy to appear when adding water mixing
Empty glass microballoon floating is not easy Hollow Glass Sphere after stirring evenly, spraying and easily floats on mortar surface, thus is to add density

Shown in table specific as follows,
The thermal coefficient of sample 7-18, reference examples 4-9 are measured respectively, and test result is as follows shown in table：
By the experimental data of table 9 it is found that when the consistent partial size of hollow glass microbead, real density is bigger, the heat insulating ability of Machine-blasting mortar
Can be poorer, and when the real density of hollow glass microbead is greater than 0.6g/cm3When, the thermal coefficient of mortar significantly increases, insulation
Property be deteriorated；When the real density of hollow glass microbead is less than 0.2g/cm3When, the thermal coefficient of mortar slightly rises, i.e., low real density
Hollow glass microbead occur during mortar mixing a degree of broken, cause thermal coefficient slightly to rise, heat preservation
Thermal insulation is deteriorated.Thus, selection real density is 0.2-0.6g/cm3Hollow glass microbead it is most appropriate.

Thermal coefficient rise, heat insulation property decline.Big partial size, low real density hollow glass microbead mixing mortar process
In, it is easily even broken because cracking caused by collision, so as to cause thermal coefficient rising.And partial size less than 2 μm when, to thermal coefficient
It has no significant effect, but the partial size of hollow glass microbead is too small, will increase the difficulty of mortar mixing.Thus, select partial size in 2-
Hollow glass microbead in 130 μ ms is most appropriate.
By the test data of table 11 it is found that under the premise of the hollow glass microbead of selection is identical, light vitreous microballon
Partial size is smaller, and the thermal coefficient of mortar is lower, but when the partial size of light vitreous microballon is less than 120 μm, the change of thermal coefficient
Change unobvious.On the other hand, when the partial size of light vitreous microballon is greater than 300 μm, the thermal coefficient of mortar obviously rises, and is unfavorable for
Improve the heat insulating effect of mortar.Therefore, the light vitreous microballon for selecting partial size to be 120-300 μm is most appropriate.
