Problems solved by technology

[0007] Steel slag and submerged arc furnace slag, as iron and steel smelting slag (also known as metallurgical slag), are associated solid wastes produced by steelmaking. Due to their poor stability and complex composition, they are difficult to handle and utilize. They are piled up in large quantities and seriously pollute the environment and occupy valuable urban land.

Embodiment 1

[0075] In parts by weight, take 50.4 parts of molding sand, 25 parts of micropowder, 24 parts of 42.5 grade high alumina cement, 0.5 part of 0202S silicone water repellent, and 0.1 part of MP-B40000 hydroxypropyl methyl cellulose ether. The specific data See Table 3. The specific specification parameters of submerged arc slag and steel slag in molding sand and micropowder are shown in the above-mentioned tables 1 and 2. Powder accounts for 50% and 50% by weight of micropowder respectively.

[0076] Put all raw material components except water in the mixer for dry material mixing, mix evenly, and then put the mixed material into a moisture-proof bag and seal it for later use.

[0077] During construction, the material is mixed with water by an electric mixer, and then applied to the wall surface by a spraying machine to form a building wall finish layer with a certain thickness, and the surface treatment is carried out. The addition of the water mixed with the material is 17%...

Abstract

The invention provides a solid waste composite inorganic facing mortar and a preparation method thereof, and belongs to the technical field of construction wall body decorative materials. The mortar comprises the following components in parts by weight: 50-60 parts of casting sand, 15-25 parts of micro powder, 15-25 parts of cement, 0.3-1.5 parts of an organosilicon water repellent, 0.2-0.5 part of hydroxyl propyl methyl cellulose ether, and a defined amount of water. The mortar serve as a low-carbon, ecologic and environment-friendly construction material, is good in performance, solves difficulty of saltpetering of a current facing mortar, and can replace currently used wall body decorative materials such as facing mortar, tiles and glass curtain walls. Moreover, the mortar has lower cost, increases safety, improves the product market competitiveness, brings good economic benefits, meanwhile exploits a new way for utilizing a steel slag resource and meets the requirements of national policy about solid waste resource cyclic utilization.

Description

technical field [0001] The invention relates to a solid waste composite inorganic facing mortar and a preparation method thereof, belonging to the technical field of building wall decoration materials. Background technique [0002] Facing mortar is a new type of building wall decoration material that has gradually emerged in recent years. It has a wide range of color changes and rich shapes. The research on this material and its production technology started relatively late in China. At present, well-known domestic facing mortar companies are all producing by introducing foreign technology or in the form of joint ventures. Finishing mortar products are mainly composed of cement, graded sand, fillers, pigments and other admixtures, and can be widely used in various building wall surfaces and ceiling decorations. [0003] Compared with the existing paint finish and ceramic tile finish, compared with the finish layer prepared by paint and other organic materials, the finish mo...
