Abstract

The invention discloses a heat retaining masonry mortar and a preparation method thereof. The heat retaining masonry mortar comprises raw material components based on parts by weight: 20-30 parts of silicate cement, 0-20 parts of medium sand, 0-20 parts of pulverized fuel ash, 0.02-0.05 part of additive and 30-70 parts of industrial furnace slag, or 1-10 parts of closed cell perlite, or 1-10 parts of EPS polyphenyl granules or the mixture of the industrial furnace slag, the closed cell perlite and the EPS polyphenyl granules; the raw material components are stirred and evenly mixed. The invention can improve the heat-insulating property, the facility value and the bonding strength of the mortar, and has low cost and simple production technique.

Description

A kind of heat-insulating masonry mortar and preparation method thereof
Technical field
The present invention relates to building material field, specifically is a kind of heat-insulating masonry mortar and preparation method thereof.
Background technology
Common masonry mortar is generally sand-cement slurry or mixed mortar.Its apparent density is generally greater than 1800kg/m 3, thermal conductivity is about 0.93w/ (m.k); And the heat insulation building block apparent density is generally 950kg/m 3, thermal conductivity is 0.15～0.45w/ (m.k).During the heat insulation building block body of wall of building by laying bricks or stones with common masonry mortar, because the thermal conductivity of the two differs bigger, cause whole masonry to have cold " heat " bridge phenomenon, because it is very big to build the power loss that mortar joint causes by laying bricks or stones, even phenomenon such as metope dewfall can appear, cause buildings to shorten and the functions of use reduction work-ing life.
At present, working-yard preparation mortar, quality instability, intensity are difficult to reach requirement, easily cause problems such as wall crazing, seepage.
Summary of the invention
The invention provides a kind of heat-insulating masonry mortar and preparation method thereof, described heat-insulating masonry mortar has intensity height, good heat insulating and Yi Du and the high advantage of cohesive strength.
Technical scheme of the present invention is:
A kind of heat-insulating masonry mortar is characterized in that: the weight part of each feed composition is: silicate cement 20～30, medium sand 10～20, flyash 15～70, admixture 0.02～0.05; Other adds: industrial slags 30～70 or closed perlite 1～10 or EPS granular polystyrene 1～10 or three's mixture.
Described a kind of heat-insulating masonry mortar is characterized in that: described admixture is selected ether of cellulose for use.
Described a kind of heat-insulating masonry mortar is characterized in that: the particle diameter≤8.0mm of described industrial slags, described closed perlite is spherical closed perlite.
The preparation method of described heat-insulating masonry mortar is characterized in that: each feed composition is mixed, throw admixture at last, stir, churning time is to pack after 15 minutes.
The preparation method of described heat-insulating masonry mortar is characterized in that: described industrial slags will be delivered to roller dryer and carry out drying treatment then through fragmentation, and the industrial slags after the drying treatment is delivered to the projection formula vibrating screen classifier and sieves processing.
It is that light-weight aggregate replaces sand that the present invention adopts slag, closed perlite, EPS granular polystyrene, improve the heat-insulating property of mortar, by changing proportioning, produce the heat-insulation masonry dry-mixed mortar of different intensity grades and different thermal conductivitys, to adapt to the insulation blocks of different heat transfer performance, reduce of the influence of masonry mortar mortar joint to wall insulation performance; Add water-keeping thickening type admixture, can make masonry mortar have better serviceability and later strength.The present invention utilizes industrial residue to be raw material, and with low cost, production technique is simple, electronics metering, mechanize production, and quality product is secure.Along with deepening continuously of building energy conservation, market outlook are wide.
