Embodiment Construction

[0012] A weather-resistant freeze-thaw thermal insulation mortar, made of the following weight (kg) raw materials: polyaluminum chloride 15, phosphate cement 60, xonotlite 22, magnesite 7, fiber stone 16, silica fume powder 12 , Porous calcium silicate 11, sawdust 8, nano-titanium dioxide 10, halloysite 20, oil shale ash 12, double fly powder 10, sesame powder 6, lithium chloride 4.5, calcium nitrite 3, polyglutamic acid 8.

[0013] A method for preparing weather-resistant freeze-thaw thermal insulation mortar, including the following steps:

[0014] (1) Mix xonotlite, silica fume powder, oil shale ash, and halloysite evenly, put them in a pulverizer, smash, sieving, and then put them into a ball mill for wet ball milling for 1 hour, and the ball mill speed is 3500r / min , The ratio of water to material is 1:5, vacuum drying, sieving, and conveying the dried powder to the arc area of ​​the plasma reaction furnace so that the powder is heated and melted. The working gas is compresse...

Abstract

The invention discloses weather-resistant freeze-thaw-resistant thermal insulation mortar and a preparation method thereof. The mortar is prepared from, by weight, 13-19 parts of polyaluminum chloride, 55-65 parts of phosphate cement, 20-25 parts of xonotlite, 5-10 parts of magnesia, 14-20 parts of satin stone, 10-15 parts of silica fume, 8-16 parts of macroporous calcium silicate, 5-10 parts of saw dust, 7-14 parts of nano titania powder, 16-24 parts of halloysite, 9-18 parts of oil shale residues, 6-12 parts of heavy calcium carbonate powder, 4-9 parts of sesbania cannabina powder, 3-7 parts of lithium chloride, 2-4 parts of calcium nitrite and 5-10 parts of polyglutamic acid. The thermal insulation mortar has the advantages of being excellent in weather resistance, good in freeze-thaw resistance, high in compressive strength, high in bonding strength, good in heat insulation, resistant to corrosion and the like.

Description

Technical field [0001] The invention relates to a weather-resistant, freeze-thaw and thermal insulation mortar and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Under the guidance of the national energy-saving policy, various provinces and cities have successively issued local regulations on building energy-saving, and implemented mandatory promotion policies for the external thermal insulation system of buildings, making the commercial mortar for external thermal insulation widely used. The thermal insulation mortar has been widely used due to its non-combustibility, convenient construction and long service life. With the rapid development of urban construction industry and the increasing improvement of people's living standards, people have higher and higher performance requirements for thermal insulation mortar. As a building insulation material, insulation mortar has been used in the past, but there are still shortc...
