Application number 200510134947.2 is introduced a kind of thermal insulation mortar, especially a kind of with glass bead as ultralight matter aggregate, the Superlight vitrification micropearl morttar that is composited by gelling material, redispersable latex powder, Mierocrystalline cellulose, fiber, starch ethers etc.Because of it is super light heat-insulation mortar, Yin Wendu or temperature and drying shrinkage produce wall body slit jointly easily, and the influence of thermal stresses also can make it produce wall body slit.
Summary of the invention
The present invention is in order to overcome defective and the problem that above-mentioned prior art exists; a kind of modified vitreous hollow beads heat-insulating fireproof mortar is provided; in the thermal insulation mortar that common glass bead, cement, rubber powder and auxiliary components are formed; add coupling agent again; make the mechanical property of thermal insulation mortar that improvement be arranged greatly, prepared ultimate compression strength and reached the above heat-insulating fireproof mortar of 1000KPa.
Technical scheme of the present invention is:
A kind of modified vitreous hollow beads heat-insulating fireproof mortar is mixed by following component, each component by weight,
Ordinary portland cement 450-500 part, glass bead 450-500 part, latex powder 13.5-15.5 part, polypropene staple 3.5-4.0 part, Vltra tears 3.5-3.8 part, water-soluble titanate coupling agent 3.5-4.0 part, 10 parts of calcium formiates.
Thinking with reference to the glass reinforced plastic modification, we also add the coupling agent of some amount in thermal insulation mortar, after test of many times, selected the kind and the add-on of coupling agent, make the mechanical property of thermal insulation mortar that improvement be arranged greatly, especially ultimate compression strength can be brought up to more than the 1MPa.
Modified vitreous hollow beads heat-insulating fireproof mortar preparation method takes multistage pre-mixing dry-mixed mortar technology, controls multiple material mixture ratio exactly, guarantees material quality compound and that all mix.
Modified vitreous hollow beads heat-insulating fireproof mortar preparation method; by above-mentioned prescription; at first ordinary portland cement, polypropene staple are dropped into stirrer; after the fly cutter operation; dropping into latex powder, Vltra tears, water-soluble titanate coupling agent, calcium formiate again mixes; drop into glass bead then and mix stirring 2-3 minute, throw in feed bin, put in storage by the metering pack by transfer roller.
Glass bead is the pearl glassiness mineral substance that the extraordinary high-temperature technology of a kind of process produces; it is a kind of high temperature resistant slight adiabatic inorganic materials; its unit weight is light, thermal conductivity is little, have fire prevention, insulation, premium properties such as heat insulation, and the thermal conductivity of its material self is 0.03W/ (mk).The glass bead Chemical Composition is as shown in table 1, and the glass bead physicals is as shown in table 2.
