Chimney white mud and mixed cotton fiber reinforced calcium silicate sheet

Abstract

A chimney white mud and mixed cotton fiber reinforced calcium silicate sheet is produced from the following raw materials by weight percent: 6-12 percent of mixed cotton fiber, 1-3 percent of fiberglass, 15-20 percent of the chimney white mud, 35-46.04 percent of quartz, 20-30 percent of common silicate cement and 1-2 percent of expanded perlite. The chimney white mud and mixed cotton fiber reinforced calcium silicate sheet has the advantages as follows: with the comprehensive utilization of the chemical white mud and recovered waste cotton tyre, the reuse value of the industrial and life waste materials is fully achieved to produce the chimney white mud and mixed cotton fiber reinforced calcium silicate sheet; the strength is high, the appearance is beautiful, and the cost is lower; not only is the problem about the comprehensive utilization of the industrial desulfurized gypsum and waste cotton tyre solved, but also the production cost of the calcium silicate sheet is lowered, the method which is reliable in technique, economical, feasible, and used for comprehensively utilizing waste resources is developed, and both the environment benefit and economical benefit are realized.

Description

technical field [0001] The invention relates to a building material, in particular to a chimney white mud mixed cotton fiber reinforced calcium silicate board. Background technique [0002] Fiber-reinforced calcium silicate board is widely used in various buildings because of its low density, fire prevention, strong sound insulation, anti-corrosion and moisture-proof, and high strength. In traditional methods, lime is used as raw material to utilize effective Ca in lime. ＋ with SiO 2 Si in ＋ In the production of calcium silicate board under certain conditions, its CaO is high, and the production environment is affected to a certain extent. [0003] Since the cost of using lime as a calcium raw material for the production of fiber-reinforced calcium silicate boards is too high, how to reduce production costs has always been an urgent problem to be solved. [0004] Chinese patent No. 201010197118 discloses the patent document titled: Lime Bamboo Pulp Fiber Reinforced Calci...

[0004] Chinese patent No. 201010197118 discloses the patent document titled: Lime Bamboo Pulp Fiber Reinforced Calcium Silicate Board. This document discloses the technical scheme of using Lime Bamboo Pulp to manufacture calcium silicate board as the main raw material. Although a breakthrough has been made, However, due to the use of lime bamboo pulp as raw material, it is necessary to increase the steps of making lime bamboo pulp during production. The process is complicated, which is not conducive to reducing the cost, the cycle is long, the efficiency is low, and the raw material is single; big, expensive
