Abstract

The invention discloses a high-property additive for a cement fiber board. The high-property additive is prepared from the following raw materials in parts by weight: 22 to 26 parts of rice husk ash,6 to 10 parts of inorganic composite superfine active filler, 3 to 6 parts of tailing sand, 9 to 13 parts of sulfate residue-doped steel slag powder, 2 to 5 parts of micro-silicon powder, and 1 to 3 parts of inorganic fiber. The high-property additive for the cement fiber board and the preparation method have the advantages that the strength of the fiber board can be improved; the density of the fiber board can be correspondingly improved; the use value is higher, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of cement fiber boards, in particular to a high-performance additive for cement fiber boards and a preparation method thereof. Background technique [0002] Cement fiberboard is a new type of building material made of silicon and calcareous materials as the main raw material, modified with natural reinforcing fibers and auxiliary materials, after pulping, copying, pressurization, and curing. It is used for exterior walls Hanging boards, indoor partitions, sound-absorbing ceilings, curtain wall linings, composite wall panels, outdoor billboards, metallurgy, electric furnace insulation panels, electrical distribution cabinets, transformer partitions, etc., according to the fibers used in them: currently domestic Most of them use asbestos fiber for reinforcement. This kind of fiber cement board is called chrysotile fiber cement board. Asbestos fiber cement board is not environmentally friendly. This is a shortc...
