Abstract

The present invention relates to a dry powder mortar composition which comprises 55 to 90% of hollow or vacuum floater, 5 to 35% of adhesives and thickening agents and 1 to 10% of lime essence. Thermal-insulating effects of masonry walls of the composition is more than two times higher than that of benzene plates, hardness or intensity after air dry is basically similar to cement, and weight is lower than 1/4 that of cement. Meanwhile, calcium formate can generate carbon dioxide gas and can react with calcium oxide so as to generate calcium carbonate, and therefore, interior wall intensity is increased.

Description

Dry powder mortar composition
Technical field:
The present invention relates to a kind of dry powder mortar composition that is used for masonry panel and mixes and after maintenance, can form hardening thing with water.
Background technology:
The subparticle aggregate with high dispersing that flyash mainly is made up of the silica glass ball, various subparticles can be divided into according to the difference of its settling property in water and float pearl, light pearl and heavy pearl.Floating pearl is a kind of spheric cenosphere, and it contains nitrogen and carbonic acid gas negative-pressure gas, has high ultimate compression strength and highly corrosion resistant rate so float pearl, and low heat-conduction coefficient and Thermal Contraction Coefficient, its fusing point are a kind of multifunctional materials more than 1500 ℃.Particularly float pearl and be used for material of construction,, can realize insulation better because the existence of the rare gas element in hollow can be controlled the free air molecule effectively and move.But, should have certain viscosity at least as the mortar of architectural use, float with regard to the pearl with regard to above-mentioned, because it is discrete particle aggregate, so it can not directly use as building mortar.
Cement is widely used as the hardening composition in mortar, concrete and the similar purposes.Roasting in stove makes as main raw material and traditional cement is usually by Wingdale, so this kind cement does not have the good characteristics such as insulation that float pearl except that wasting energy and causing the environmental pollution, for this reason, the main research topic that pearl making cement has become this area is floated in utilization.
Just utilized as " the superconduction special cement " of CN1096277A bulletin and to have floated pearl, this kind cement is base-material with 100 parts of Portland clinkers, add 5-20 part alunite, 5-25 part gypsum combined grinding is to cement fineness, and what add 10-45 part flyash extract again floats pearl and microballon.This kind cement to float the pearl utilization ratio the highest only in about 20% of gross weight, the problem of its insulation, unit weight and aspect such as impervious can only be improved at most about 20%, forms this aspect and does not have much changes, major part is also still keeping the fundamental characteristics of traditional cement.
And " hollow centered microbead portland cement " of CN1061014A bulletin pays attention to improving the ratio of cenosphere, in a scheme that provides, the weight percent of cenosphere content is 15-65%, and is that its adding is made in the silicate cement that roasting constituted by Wingdale, clay, iron powder.This cement is the same with similar cement such as common silicate or flyash, in use, needs by predetermined proportion filling sand or analogue, and can not directly make mortar or concrete uses; Secondly, this kind cement is actually and utilizes silicate cement as binding agent, and the performance of aspects such as intensity after its aquation and insulation does not obtain basic improvement yet.
Summary of the invention:
Task of the present invention provide a kind of utilize slag granules for major ingredient make have excellent insulating effect and an ideal tensile strength and the direct dry powder mortar composition that uses of aquation.
Dry powder mortar composition proposed by the invention, the hollow or vacuum that contains 55-90% is floated binding agent and the thickening material of pearl and 5-35%, and the lime extract of 1-10%, and the weight ratio between described thickening material and the binding agent is 1: 50-90.Owing to have rare gas element or carbonic acid gas negative-pressure gas in the hollow float bead, it can suppress the motion of air free molecule effectively, it can hinder the heat conduction, increase the bounce-back speed of air molecule, therefore, seek out insulation and the good mortar of other performance, the content that floats pearl in the mortar should be that big more its performance is good more, consider the problem of the aspects such as intensity after the mortar aquation, the content that floats pearl should not surpass 90%; Simultaneously, need an amount of adhesion agent and thickening material and cooperate with it, and the content of adhesion agent and thickening material should not be lower than 5%; In addition, that lime extract has is early strong, the function of increase-volume, loss of weight, and one kilogram of lime extract can replace 2,500 kilograms of cement.
Described binding agent is made of high-alumina cement or magnesia oxychloride cement or both mixtures; Described thickening material is made of ether of cellulose, and to make the weight ratio between thickening material and the binding agent be 1: 50-90.
Hollow or the vacuum that contains 70-80% is floated the lime extract of pearl, 10-25% binding agent, 2-6%, the ether of cellulose of 1-5 ‰ and the calcium formiate of 1-5%.
Described ether of cellulose is made of ionic Mierocrystalline cellulose or non-ionic type Mierocrystalline cellulose.
Described ionic Mierocrystalline cellulose comprises carboxymethyl cellulose, and the non-ionic type Mierocrystalline cellulose comprises ethyl cellulose or methylcellulose gum or Natvosol.
Hollow or the vacuum that contains 80-90% is floated the lime extract of pearl, 10-25% binding agent, 2-6%, the ether of cellulose of 1-5 ‰ and the calcium formiate of 1-5%, and the above-mentioned substance sum is 100%.
Dry powder mortar composition proposed by the invention adopt hollow or vacuum to float pearl be major ingredient, add binding agent and thickening material, and lime extract etc. is mixed and made into, owing to float the characteristic that pearl has insulation and light weight, so, can improve more than 2 times than the heat insulation effect with the benzene plate with its masonry panel, hardness after it is air-dry or intensity and cement are close substantially, and weigh less than more than 3 times of cement; Simultaneously, owing to contain calcium formiate in the mixture, calcium formiate can produce carbon dioxide, when this mixture with after water mixes, with in its body of wall of building by laying bricks or stones because the increase of carbon dioxide and calcium oxide react generation lime carbonate, and then can increase the intravital intensity of wall.
