A kind of blast furnace slag/plant ash composite lightweight partition wall board and its manufacturing method

Abstract

The invention discloses a blast furnace slag / plant ash compound lightweight partition wall board. The lightweight partition wall board is characterized by being manufactured from the following raw materials in parts by weight: 11-14 parts of cement, 9-13 parts of kaolin tailings, 14-19 parts of geopolymer, 0.4-0.9 part of sodium silicate, 13-16 parts of plant ash, 0.2-0.5 part of fatty alcohol-polyoxyethylene ether, 18-23 parts of blast furnace slag, 0.7-2.1 parts of dicumyl peroxide, 1-2 parts of dimethyl phenyl sodium sulfonate, 4-7 parts of paraffin oil, 3-6 parts of aids and a proper amount of water. The blast furnace slag, the plant ash and the like are added to the raw materials after being subjected to high-temperature calcining treatment, so that harmful gases such as formaldehyde in air can be adsorbed, and the lightweight partition wall board is waterproof, high-temperature resistant and light in volume weight, can be widely applied to house decoration partition walls and is good in field practicability.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a blast furnace slag / plant ash composite lightweight partition wall board and a manufacturing method thereof. Background technique [0002] The lightweight partition board is a new type of energy-saving wall material composed of harmless phosphogypsum, light steel slag, fly ash and other industrial waste residues, and is cured by frequency conversion steam under pressure. The wall material is the same as the hollow floor slab, but there are male and female falcon grooves on both sides. When installing, you only need to stand up the board, and the male and female falcons can be assembled after applying a small amount of caulking mortar. It has the advantages of light weight, high strength, multiple environmental protection, thermal insulation, sound insulation, respiratory humidity control, fire prevention, rapid construction, and reduced wall cost, so it is very popular in the f...

AI Technical Summary

Problems solved by technology

It has the advantages of light weight, high strength, multiple environmental protection, thermal insulation, sound insulation, respiratory humidity control, fire prevention, rapid construction, and reduced wall cost, so it is very popular in the field of architectural interior decoration. Quality partition wall panels have disadvantages such as low compressive strength, weak tensile strength, poor crack resistance and hanging ability, high production cost, and poor sound insulation and heat preservation effects.
