The functional chemical admixtures consists essentially of hydrophobic agent taking hydrophobic effect, such as SEAL80 of organic silicon, zinc stearate, etc. cellulose ether and guar gum taking water retention and viscosity-phobic effects, polyvinyl alcohol taking thickening and foam stabling effects, re-dispensable latex powder taking water resistant and flexibility increasing effects and a little amount of air-entraining agent for lowering the volume and the density and reducing the thermal conductivity. With the common functions of the admixtures, the construction performance, the water resistant performance and the bond strength of the heat insulation mortar are improved. The invention can be used for the heat insulation of the external walls.

Description

The mortar that heat preservation and thermal insulation of building outer wall is used
Technical field
The invention belongs to a kind of material of construction, specifically is the mortar that a kind of construction wall heat insulating is used.
Background technology
The inorganic mineral light heat-insulation mortar of Xiao Shouing in the market, with the inorganic mineral light grains for gathering materials, with cement, breeze, flyash and grey calcium is gelling material, because poor performance, cohesive strength is low, and volume density is big, reasons such as water-intake rate height, can only be used for the interior insulation of body of wall, and can not be used for external wall outer insulation, particularly workability can not meet the demands.
Summary of the invention
The invention provides the mortar that a kind of construction wall heat insulating is used, with the inorganic mineral light grains for gathering materials, cement, breeze, flyash and grey calcium are in the inorganic mineral light heat-insulation mortar of gelling material, mixed in addition and have various functional chemical admixtures and fortifying fibre etc., because the cohesive strength height, volume density is little, water-intake rate is low, water resistance is strong, has good workability, and can be used for external wall outer insulation.
Technical scheme of the present invention is as follows:
The mortar that a kind of heat preservation and thermal insulation of building outer wall is used is characterized in that: with the inorganic mineral light grains for gathering materials, be to have added following composition by weight in the inorganic mineral light heat-insulation mortar of gelling material with cement, breeze, flyash and grey calcium:
Latex powder 2-5%
Hydrophober 0.3-1.2%
Fiber 0.5-5%
Described latex powder is meant ethene/vinyl laurate/vinylchlorid terpolymer latex material, described hydrophober is meant SEAL80, Zinic stearas or calcium stearate or its mixture, described fiber is meant vegetable fibre or man-made fiber, and vegetable fibre refers to wood fibre, paper fiber, crops stalk comminuted fibres.
Perhaps, in described mortar, also added following composition by weight:
Ether of cellulose 0.5-1.5%
Described ether of cellulose refers to hydroxyethyl methyl fiber HEMC, Vltra tears HPMC, and its viscosity is at 70000PS-200000PS.
Perhaps in described mortar, also added following composition by weight:
Guar gum or guar gum+xanthan gum 0.5-1.5%.
Perhaps in described mortar, also added following composition by weight:
Ether of cellulose 0.5-1.5%
Float pearl 0-10%
Described ether of cellulose refers to hydroxyethyl methyl fiber HEMC, Vltra tears HPMC, and its viscosity is at 70000PS-200000PS; It is described that to float pearl be isolated pearl or the made microballon of floating in the flyash.
Perhaps in described mortar, also added following composition by weight:
Ether of cellulose 0.5-1.5%
Air entrapment agent 0.1-0.5%
Suds-stabilizing agent 0.2-0.5%
Described ether of cellulose refers to hydroxyethyl methyl fiber HEMC, Vltra tears HPMC, and its viscosity is at 70000PS-200000PS; Air entrapment agent refers to sodium lauryl sulphate RN6031, sodium laurylsulfonate, alkylbenzene sulfonate etc., and suds-stabilizing agent refers to polyvinyl alcohol 0588,1788,2488.
The mortar that described heat preservation and thermal insulation of building outer wall is used is characterized in that: during the compound interpolation of guar gum+xanthan gum, its weight ratio is 6: 4; Described ether of cellulose viscosity is at 100000PS-200000PS.
The present invention is at the manufacturing condition that does not change original inorganic mineral light heat-insulation mortar, only in the ratio of components of inorganic mineral light heat-insulation mortar, particularly work hard on the chemical admixture, selected multiple functional admixture, improved the workability of thermal insulation mortar, water-retentivity, water tolerance reduce stem body density, improve cohesive strength.
The present invention has at first studied the workability of inorganic mineral light heat-insulation mortar, cohesiveness was too poor when original mortar was constructed, loose sense is arranged, being difficult for floatingly, is that the viscosity of used ether of cellulose is less with regard to its reason, and volume is low again, the general ether of cellulose viscosity of using is between 4-7 ten thousand, the present invention uses ether of cellulose viscosity between 10-20 ten thousand, but also has used a kind of guar gum and the compound use of xanthan gum, and effect is obvious.
Secondly, the water-intake rate that the present invention has studied the inorganic mineral light heat-insulation mortar is too big, coefficient of softening is little, can not be used for external heat insulating wall, the present invention has used the hydrophober of silicone based hydrophober such as SEAL80 and fatty acid such as Zinic stearas, calcium stearate, reduced the water-intake rate of thermal insulation mortar, coefficient of softening obviously improves.
For improving the water tolerance of thermal insulation mortar, cohesive force and flexibility, redispersable latex powder is indispensable, latex powder is various in style in the market, should select the water tolerance height, flexibility is latex powder preferably, and ethene/vinyl laurate/vinylchlorid terpolymer latex powder VINNAPAS RI5542 and 51Z are just better.
In order to reduce the stem body density and the thermal conductivity of thermal insulation mortar, the present invention adopts air entrapment agent and suds-stabilizing agent, and effect is obvious, mixes air entrapment agent and can generate countless small bubbles, as ball one by one, the workability of mortar is obviously improved.Have air entrapment agent and suds-stabilizing agent to sell in the market, air entrapment agent is mainly sodium lauryl sulphate, sodium laurylsulfonate, alkylbenzene sulfonate etc., suds-stabilizing agent be thickening power arranged colloid all can, be thickening suds-stabilizing agent commonly used as polyvinyl alcohol.
Use man-made fiber in the inorganic mineral light heat-insulation mortar at present more, its practical vegetable fibre is better, good and cheap, dispersiveness is good again, except that increasing tensile strength, also can play the water-keeping thickening effect, can reduce stem body density, the present invention has used wood fibre, paper fiber and crops stalk comminuted fibres, has all obtained good effect.
It also can be closed perlite, pearlstone, expanded vermiculite etc. that inorganic light-weight aggregate in the thermal insulation mortar mainly contains glass bead at present; the intensity of these materials is not high; in order to improve the intensity of thermal insulation mortar; can mix an amount of hollow glass bead; float pearl or made cenosphere as what sub-elect in the flyash; but the price of this material is more expensive, can use when special requirement are arranged.
