Problems solved by technology

In order to deal with these waste residues, the country spends a huge amount of money every year to build slag dumps and railway lines, wasting a lot of manpower and material resources. Whenever there is windy weather, sand and dust are everywhere, and when there is heavy rain, the sand and sand pour down, occupying farmland, polluting water sources, and causing serious damage to the land. The ecological environment has caused serious harm

Embodiment 1

[0019] Such as figure 1 with figure 2 Shown is the schematic structural view and cross-sectional view of the slag polystyrene foam composite lightweight sandwich panel of the present invention, the slag polystyrene foam composite lightweight sandwich panel is cast slag slurry on the polystyrene foam board 3 Made of surface material 2, there are two lateral grooves 4 on both sides of the sandwich panel, the grooves can be trapezoidal, semicircular or triangular for installation. The ground slag powder, sulphoaluminate cement, desulfurized building gypsum, Glauber's salt, and quicklime are used as raw materials to mix evenly in proportion, and then add water and stir to form a slurry. Using a forming mold, apply the slurry on the upper and lower surfaces and both sides of a polystyrene foam board with a length of 2500mm, a width of 500mm, and a thickness of 40mm, and release the slurry after it is completely hardened. The slag lightweight sandwich panel surface material of th...

Abstract

The invention belongs to the technical field of novel building materials and relates to a light sandwich panel which uses slags as main surface materials and is manufactured by compounding on a polystyrene foam plastic panel core material, wherein, the sandwich panel is provided with ladder-shaped, triangular or semi-circular grooves at both sides. The surface materials coated on the exterior of the polystyrene foam plastic panel in the invention are manufactured by the following raw materials in parts by weight: 100 parts of slag powder, 2-7 parts of sulphate aluminium cement, 1.5-5.5 parts of desulfurized building gypsum, 0.5-5 parts of mirabilite and 4-11 parts of quicklime; the mass ratio of the water to the raw materials is 0.45 to 0.70. The product of the invention has the performance up to the national quality standard, is light in weight and high in strength, has the functions of thermal insulation, sound insulation and the like, and is a wall material that can be applied to frame-structured buildings.

Description

technical field [0001] The invention belongs to the technical field of new building materials, and relates to a lightweight sandwich panel for frame structure buildings made of blast furnace slag as the main raw material. Background technique [0002] Most of the traditional wall materials are solid clay bricks, which not only consume a lot of energy, but also seriously damage the cultivated land. In recent years, with the implementation of national policies such as restricting and prohibiting the use of solid clay bricks, various new wall materials have emerged in an endless stream. At present, the frame structure building has quietly risen in our country, and it is getting hotter and hotter. The enclosure wall is the main component of the frame structure building. In the frame structure building, the wall body is required to have light weight, heat insulation, sound insulation, impact resistance, fire prevention and other properties. Lightweight wall materials used as en...
