Description
Technical field
The present invention relates to thermal insulation mortar technical field, be specifically related to a kind of scoria thermal insulation mortar and preparation method thereof.
Background technology
In recent years, various solid wastes and urban construction removal that industrial processes produce remake the solid waste etc. brought and annoying the living environment of resident always, solid waste is added in thermal insulation mortar as raw material by the present invention, achieve the cyclic utilization of waste, decrease the pollution to environment, meet strategy of sustainable development requirement.
Thermal insulation mortar is with various light materials as aggregate, with cement as gelating material, admixes some property-modifying additives, adds water through manufacturing enterprise and stirs a kind of premixing dry powder and mortar mixed and make.Can be not only used for external wall external thermal insulation, it is also possible to for exterior wall internal insulation, or be incubated inside and outside exterior wall simultaneously, and the insulation on roof and the thermal insulation layer of underground heat, provide certain motility for the design of energy-saving system.There is the advantages such as easy construction, good endurance, light weight, insulation, thermal insulation be good.But existing tradition mortar heat preserving and insulating material, such as poly-stupid granule heat-insulating mortar, Margarita thermal insulation mortar etc., in use expose many defects, such as surface hollowing, ftracture, come off, easily go mouldy, it addition, the porosity of major part thermal insulation mortar is higher, therefore overall water absorption rate is the highest, not only can reduce the intensity of material after water suction, and its heat-insulating property can be reduced greatly.Therefore, a kind of novel anti-aging, corrosion-resistant, cracking resistance, insect protected, thermal insulation mortar that the multi-functional intensity such as degerming is high demand extremely urgent.
Summary of the invention
It is an object of the invention to provide a kind of scoria thermal insulation mortar and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of scoria thermal insulation mortar, it is characterized in that, be prepared by the raw materials in: cement 280-350, scoria 200-260, rock 190-230, ceramic fine bead 35-40, doughnut 18-25, prodan 10-13, meerschaum 110-170, Caulis Sacchari sinensis straw 90-135, maltodextrin 7-9, lignosulfonates 9-11, sodium pyrophosphate 4-7, auxiliary agent 3-6 inferior.
