Fiber cement board based on industrial solid waste and preparation method

Abstract

The invention relates to a fiber cement board based on industrial solid waste and a preparation method thereof, and the fiber cement board comprises the following raw materials by mass: 1-7 parts of cellulose fiber; 1-6 parts of synthetic inorganic fiber; 5-20 parts of limestone fiber; 30 to 90 parts of cement; 10 to 20 parts of gold tailings; 10-20 parts of gold ore sand; 10 to 55 parts of gold tail mud; 5 to 40 parts of fly ash; 5-40 parts of stone powder; 5-40 parts of steel slag; 5 to 40 parts of glass powder; 3 to 30 parts of aluminum powder; 5 to 40 parts of sludge; 5-60 parts of power plant ash; 5-45 parts of industrial tailing powder; 1-20 parts of a nano material; 1 to 25 parts of diatomite; 1-20 parts of an active additive; 1 to 15 parts of a defoaming agent; 0.1 to 15 parts of polyacrylamide; the weight of the water is 1-10 times of the total weight of the materials; wherein the cement is Portland cement prepared by taking industrial solid waste as a raw material. The energy consumption is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fiber cement board based on industrial solid waste and a preparation method. Background technique [0002] Traditional fiber cement board is a kind of board mainly made of ordinary silica cement as inorganic gelling agent and basic material, fiber material as reinforcing material, and by adding appropriate amount of admixtures, through pulping, molding, curing and other processes. , is widely used in the field of production and construction, for example, as decorative panels for interior and exterior walls, floor panels, ceiling panels, composite insulation panels, fireproof panels, etc. [0003] The strength of the traditional fiber cement board is mainly composed of ordinary silicon cement, quartz powder, silica fume, etc. through high temperature steam curing hydration reaction. After the traditional fiber cement board wet blank is prepared, it is mainly through t...

Problems solved by technology

[0003] The strength of the traditional fiber cement board is mainly composed of ordinary silicon cement, quartz powder, silica fume, etc. through high-temperature steam-cured hydration reaction. After the traditional fiber cement board wet billet is prepared, it is mainly through high-temperature autoclave curing to speed up the siliconization process. Calcium reaction rate, although this improves the production efficiency of traditional fiber cement boards to a certain extent, it also greatly intensifies energy consumption, and there are still environmental problems in the waste gas and waste water generated in the autoclave curing process
