Abstract

The invention relates to a composite thermal insulating mortar formula for building exterior walls. The formula comprises Portland cement, ground calcium carbonate, coal ash, slag, sepiolite, glass beads, rubber powder, crack-resisting fibers, polyacrylamide and hydroxypropyl methylcellulose ether. The method includes adding the Portland cement, the ground calcium carbonate, the coal ash, the slag, the rubber powder, the crack-resisting fibers, the polyacrylamide and the hydroxypropyl methylcellulose ether in order into water in a stirrer, adding the sepiolite and the glass beads, and stirring fully to obtain a finished product. Application of the ground calcium carbonate, the coal ash and the slag reduces the overall cost, and improves toughness and strength. Application of the rubber powder, the crack-resisting fibers and the polyacrylamide improves mechanical strength and bonding strength. The sepiolite and the glass beads improve thermal insulating effects. Through testing, compressive strength of a test block is higher than 0.5 kPa, the dry apparent density is less than 240 kg/m<3>, and the coefficient of thermal conductivity is less than 0.05 w/m.DEG C.

Description

A kind of skin composite thermal insulation mortar formula and its preparation method
Technical field
The invention belongs to thermal insulation mortar technical field, especially a kind of skin composite thermal insulation mortar formula preparation method.
Background technology
Thermal insulation mortar is a kind of energy-saving mortar material whitewashed for skin, take cement as gelating material, and some property-modifying additives of blending, through being uniformly mixed a kind of premixing dry-mix made, have the feature such as easy construction, good endurance. The thermal insulation mortar sold on market is mainly two kinds: 1. inorganic heat insulation mortar: comprise glass bead Fireproof thermal insulation mortar, perlite heat-insulating mortar; 2. organic heat-insulating mortar: comprise polyphenyl particle heat-insulating mortar. Inorganic heat insulation mortar wherein have acid and alkali-resistance, corrosion-resistant, do not ftracture, do not come off, advantage that stability is high, and during its construction, can directly spread upon blank wall surface, the machine tool of construction is simple, short construction period, resistivity against fire, intensity, mildew-resistant, water-fast etc. in all there is good performance, but the increase along with people's demand, the requirement of thermal insulation mortar performance is more and more higher, it is badly in need of that a kind of cost is cheaper and the better thermal insulation mortar of performance.
