Abstract

An anti-cracking thermal-insulating cement mortar is characterized by being prepared from the following raw materials in parts by weight: 300-340 parts of cement, 14-18 parts of nano attapulgite, 1-2 parts of lignosulfonic acid, 30-35 parts of sodium carboxymethylcellulose, 30-35 parts of waste building brick powder, 3-4 parts of sodium silicate, 6-9 parts of sodium fluosilicate, 40-45 parts of crushed crude pearlite powder, 4-6 parts of guar gum, 10-12 parts of polyoxyethylene, 3-5 parts of sodium sulfamate, 10-12 parts of magnesium silicate, 4-6 parts of modified nano carbon powder and 600-650 parts of water. According to the invention, the problems that cracking and hollowing occur to an existing mortar material, and the adhesive property of the existing mortar material is poor are solved; the setting and hardening rates of the anti-cracking thermal-insulating cement mortar are high; the anti-cracking thermal-insulating cement mortar is suitable for construction in winter and other severe weather, and has good fireproof, acid and alkali resistant, thermal insulating and sound absorbing properties.

Description

Cracking resistance cement heat preserving mortar and preparation method thereof
Technical field
The invention belongs to building material field, be specifically related to a kind of cracking resistance cement heat preserving mortar and preparation method thereof.
Background technology
China's exterior-wall heat insulation comprises organic heat-insulating system and inorganic heat preservation system and organic and inorganic composite heat-insulating material three classes.Wherein, be mainly organic lagging material, production and operating technique are very ripe, but can not prevent fires, and contaminate environment is easily aging.Mineral-type thermal insulation mortar material is because its finished product is low, and intensity is high, insulation, and fire prevention, the advantages such as weathering resistance are paid close attention to widely, but still have the shortcomings such as cost is higher, material source is limited, still have improved space.
Along with the use of the discarded building solid castoffs such as concrete blocks, standard fragment of brick and (hollow) air-entrained concrete building block of development of building green construction has become energy-conservation requirement and the material that generally uses, but because its volume is larger, intensity is relatively low, therefore be easy to produce the destruction of rib arrisdefect due to misoperation in handling process, this part building block can not be on main construction.The solid waste of these destructions is transported producer's aerating or work as building waste and throw away again often back.Utilize these building wastes as mortar material, can be salvaged, there is environmental benefit.
Summary of the invention
The object of this invention is to provide a kind of cracking resistance cement heat preserving mortar and preparation method thereof.
Technical scheme of the present invention is as follows:
A cracking resistance cement heat preserving mortar, is characterized in that being made by the raw material of following weight part: cement 300-340, nano-attapulgite 14-18, lignosulfonic acid 1-2, Xylo-Mucine 30-35, building useless brick powder 30-35, water glass 3-4, silicofluoric acid are received 6-9, perlite powder 40-45, guar gum 4-6, polyoxyethylene 10-12, thionamic acid sodium 3-5, Magnesium Silicate q-agent 10-12, modified Nano carbon dust 4-6, water 600-650; Described modified Nano carbon dust is made by the raw material of following weight part: nano-sized carbon 10-11, jade powder 20-24, Sodium Benzoate 1-2, Radix Angelicae Sinensis oil 1-2, Tremoliteor Tremoliteasbestos powder 2-3, Silane coupling agent KH550 1-2, Sodium Selenite 1-2, gynostemma pentaphyllum powder 1-2; Each material composition is mixed, and grinding distribution evenly and get final product.
The preparation method of described cracking resistance cement heat preserving mortar, it is characterized in that, by mixing except other later composition of cement, being heated to 60-70 ℃, stirs 20-30 minute, and form slurry, then adds cement mixing become lotion and get final product.
The present invention can solve the poor problem of crack, hollowing and adhesive property that existing mortar material exists, and setting and harden speed is fast, is suitable for the severe weather constructions such as winter, and has good fire prevention, acid and alkali-resistance, heat insulating and sound absorption qualities.
Embodiment
