Abstract
The invention provides coating mortar. The coating mortar comprises the following ingredients, by weight, 350-400 parts of cement, 350-480 parts of sands, 75-150 parts of filling materials, 2-3.5 parts of hydroxypropyl methyl cellulose, 25-30 parts of redispersible powder and 3-5.5 parts of early strength agents. Due to mixed usage of the filling materials, the hydroxypropyl methyl cellulose and the redispersible powder, the intermolecular attractive force is increased, which facilitates to increase the bonding force of the coating mortar. In addition, the bonding force of the coating mortar is raised greatly in a condition of weight part ratios of the filling materials, the hydroxypropyl methyl cellulose and the redispersible powder, and coating mortar with a strong bonding force and good flexibility can be obtained in cooperation with usage of the early strength agents.
Description
Technical field
The present invention relates to building material field, particularly a kind of plastering mortar.
Background technology
Plastering mortar, is also called motar, refers to the surface spreading upon buildings and component surface and base material, has protection basic unit and the mortar meeting service requirements effect concurrently.Plastering mortar smears formation float coat, and float coat is bearing load not, but float coat and stratum basale will have enough cohesive strengths, makes it in construction or does not come off under long-term deadweight and environmental activity, do not ftracture.Existing plastering mortar formula cohesive force is low, and snappiness is poor, causes easily coming off during use, easy to crack, has influence on construction quality.
Summary of the invention
It is strong that the technical problem to be solved in the present invention is to provide a kind of cohesive force, the plastering mortar that snappiness is good.
For solving the problems of the technologies described above, plastering mortar provided by the invention comprises following component by weight:
The used in combination of above-mentioned filler, Vltra tears and redispersable latex powder makes the gravitation between molecule increase, thus be conducive to the cohesive force increasing plastering mortar, and under filler disclosed by the invention, Vltra tears and redispersable latex powder weight ratio condition, the bonding of plastering mortar improves greatly, coordinate the use of hardening accelerator again, cohesive force can be obtained strong, the plastering mortar that snappiness is good.
The cement type that above-mentioned cement can use this area conventional, those skilled in the art can select according to the actual requirements flexibly, and preferably, described cement is 425# ordinary portland cement.
Preferably, described sand material is the quartz sand or dry husky of 60 order-80 order granularities, and more preferably, described sand material is the quartz sand of 60 order-80 order granularities.
Preferably, filler is dicalcium powder or the flyash of 80 order-120 order granularities, and more preferably, described filler is the dicalcium powder of 80 order-120 order granularities.
Preferably, the viscosity of described Vltra tears is 40000-70000, and the plastering mortar cohesive force in this Vltra tears range of viscosities is excellent, and easy to use during plastering mortar construction, easily smears or brushes.
Preferably, described redispersable latex powder is the multipolymer of styrene-butadiene-styrene or ethylene-vinyl acetate, and the amount of redispersable latex powder is not obvious to the improvement of mortar performance very little, easily causes plastering mortar to harden too much.
Preferably, described hardening accelerator is calcium formiate, adds the use sense that hardening accelerator is conducive to improving plastering mortar.
Preferably, also comprise the hydrophobic pearlite counting 80-160 part by weight, above-mentioned hydrophobic pearlite is with hydrophobic film, water-intake rate is little, lightweight, and hydrophobic pearlite is irregular spherule particle, inside is cavity structure, surface is in vitreous closed state, closed stratum has certain change, physicochemical property is stablized, there is light weight, heat-insulating, fire-preventing, high-low temperature resistant, anti-aging good characteristic such as grade, be added in plastering mortar, there is good application property, be conducive to the density reducing plastering mortar, thus reduce the self gravitation of plastering mortar, improve the security of plastering mortar.The plastering mortar intensity that with the addition of this weight part hydrophobic pearlite is large, and snappiness is good, and water-intake rate is little, good heat insulating.
More preferably, the granularity of described hydrophobic pearlite is 0.5mm-1mm, and tap density is 0.08g/cm
3-1.6g/cm
3, thermal conductivity is 0.048w/mk-0.054w/mk.
Preferably, also comprise the nonionic surface active agent counting 20-30 part by weight, above-mentioned nonionic surface active agent preferably can be Determination of Polyoxyethylene Non-ionic Surfactants.Nonionic surface active agent is spiked into plastering mortar can improve its intensity and toughness greatly, improve the stability of plastering mortar, and nonionic surface active agent can protect hydrophobic pearlite effectively, avoids hydrophobic pearlite damaged.
Embodiment
For enabling above-mentioned purpose, the feature and advantage of invention more become apparent, below the specific embodiment of the present invention is described in detail.
Set forth a lot of detail in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention, therefore the present invention is by the restriction of following public specific embodiment.
The performance perameter table of table 1 plastering mortar
Under the condition knowing concrete component content, plastering mortar of the present invention can be obtained by methods known in the art, preferably prepare as follows:
1,425# ordinary portland cement, quartz sand, dicalcium powder, Vltra tears, styrene-butadiene-styrene, calcium formiate, hydrophobic pearlite, nonionic surface active agent is selected to provide the one-tenth of plastering mortar to be grouped into as raw material, calculate the consumption of raw material by the composition proportion of embodiment in table 1, after weighing, be mixed to get basestocks;
2, in basestocks, add a certain proportion of water (add-on of water is selected according to the actual requirements, usually can be 25% to 50% of basestocks gross weight), stir 1.5h-3h, obtain plastering mortar.
As shown in table 1, plastering mortar cohesive force of the present invention is strong, snappiness is good, and finished product plastering mortar is by strong for bonding force, insulation, heat insulation, environmental protection, fire prevention, do not ftracture, the green energy conservation material that various performance combines together such as hollowing, smooth surface and easy construction be not quick.
Although the present invention is described in conjunction with above embodiment, but the present invention is not defined to above-described embodiment, and only by the restriction of claims, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present invention and scope.
