Abstract
The present invention provides a hollow silicon diatomite composite building heat-insulating coating material which is made of hollow silicon, expanded perlite powder, diatomite, light calcium powder, rock wool, acrylic emulsion and water as raw material. Said coating material has good heat-insulating performance, and the thickness 1.5-2.5 cm of said heat-insulating coating layer applied on the wall is identical to thickness 3-5 cm of polybenzene plate in heat-insulating efficiency.
Description
Technical field: the present invention relates to a kind of material of construction, promptly a kind of hollow silicon tripolite compound building thermal-insulating coating.
Background technology: the heat-insulating property of body of wall, that is heat-proof quality are one of covil construction performances that must possess.At present, the wall thermal insulation technology kind is a lot, developed countries such as Great Britain and America adopt the prefabricated thermal insulation wallboard more, countries such as Russia, the Mongolia ways that add thick wall body that adopt more, China adopts the lower starting material of heat conductivility more, for example uses flyash, diatomite, materials such as fine perlite are made the concrete block masonry body of wall, and the employing styrofoam that also has is attached on the metope.But these methods, cost is higher, construction inconvenience, the difficulty that also has is mutually bonding with other materials, brings difficulty for follow-up engineering.The wall of the styrofoam veneer that for example present northern China city begins to adopt just is difficult to combine with the husky ash of cement, needs to cover the close plating grid, smears concrete grey again twice, wipe complex process, cost height off with putty, the square meter cost is up to 75 yuans, and visual appearance also is difficult to guarantee.Thereby people wish to have a kind of good heat insulating, and construction process is simple, and the coating that cost is lower again replaces present wall heat insulation material., the existing coating for wall surface of China, main effect is to decorate and corrosion protection, the thermal insulation coatings that is suitable for covil construction yet there are no report.Late nineteen nineties, provinces such as Sichuan, Hubei develop a kind of sepiolite coating in succession, and heat insulation effect is fine, because cost is too high, can only be used for the insulation of hot and cold equipment and pipeline, can't widely apply on building wall.
Summary of the invention: the objective of the invention is to develop a kind of good heat insulating, easy construction, lower-cost building thermal-insulating coating.Above-mentioned purpose is that following technical scheme realizes: get hollow silicon 3-7 part by weight, and swelling perlite powder 1-3 part, diatomite 2-5 part, light calcium carbonate 3-7 part, rock wool 1-3 part, acrylic acid emulsion 8-12 part, water 60-80 part is mixed to stir and is made coating.
Said mixing process is: earlier rock wool and swelling perlite powder are put into container, add hot-water soak 20-25 hour; In another container, add entry, hollow silicon, diatomite, lightweight charcoal acid calcium, stir evenly, left standstill at least 1 hour, add the acrylic acid emulsion again, stirring at low speed lumps together material in two containers after 0.5 hour at least again, stirring at low speed left standstill more than 1 hour more than 1 hour.
Said hollow silicon can adopt the light body particle of selecting in the flyash, claims flyash to float pearl again.
Adopt the coating of such scheme, thermal conductivity≤0.06, on wall, brush 1.5-2.5cm, can reach the rock wool of 3-5cm or the heat insulation effect of styrofoam, it is thick to make the thick brick wall of 50cm be kept to 37cm, and raw material is easy to get, easy construction, paste closely with existing metope, square meter cost≤45 yuan, thereby have very considerable application prospect.
Embodiment: get rock wool 20kg, swelling perlite powder 20kg puts into the stirring at low speed jar, soaks 24 hours with boiling water 20kg; With hollow silicon 50kg, diatomite 30kg, light calcium carbonate powder 50kg, water 500kg put into another low speed and stir to block in the jar and stir, and leave standstill 2 hours, add elastic emulsion acrylic acid 100kg then, stirring at low speed 12 hours.The material in back one jar is added in last jar, stirring at low speed 2 hours left standstill 2 hours again.Sampling inspection, the qualified finished product that is.
