Problems solved by technology

Low-alkali early-strength cement extruded boards have high strength, fast hardening, high production efficiency, and low drying shrinkage. low, and gradually withdraw from the market
Ordinary cement extruded board, due to its low cost, still has a certain low-end market, but due to the incomplete curing of ordinary cement extruded board, high drying shrinkage rate, and easy cracking after the wall is formed, the application range is getting smaller and smaller

Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment.

[0020] (1) Example of optimal proportioning of dihydrate gypsum (desulfurized gypsum) and fluorine gypsum

[0021] The main raw materials are dihydrate gypsum (desulfurized gypsum), fluorine gypsum, water-quenched slag powder, cement, lime, expanded perlite, and slag, and their weight ratio is:

[0022] Dihydrate gypsum: fluorine gypsum: water-quenched slag powder: cement: lime: expanded perlite: slag

[0023] 1#=0:600:300:100:10:40:1100

[0024] 2#=100:500:300:100:10:40:1100

[0025] 3#=300:300:300:100:10:40:1100

[0026] 4#=400:200:300:100:10:40:1100

[0027] 5#=400:300:400:100:10:40:1100

[0028] 6#=450:250:300:100:10:40:1100

[0029] 7#=500:100:300:100:10:40:1100

[0030] 8#=600:0:300:100:10:40:1100

Abstract

The invention relates to a high-strength waterproof extrusion molding gypsum-based composite ecological wallboard and is made of the following materials with the following weight ratio: 15 to 56 percent of gypsum binding material, 10 to 20 percent of potential active powder, 3 to 15 percent of alkali-activator, 30 to 80 percent of filler, 0 to 1.0 percent of strengthening material, 0 to 3 percent of accelerant, 0 to 0.8 percent of early strength agent, 0 to 1 percent of water reducing agent and 0 to 0.5 percent of retarder. The high-strength waterproof extrusion molding gypsum-based composite ecological wallboard is high in strength, good in waterproof performance, low in production cost, low in drying shrinking rate, fast in hardening, and high in performance-price ratio.

Description

technical field [0001] The invention relates to a lightweight porous wallboard, in particular to a high-strength water-resistant extruded gypsum-based composite ecological wallboard. Background technique [0002] Reinforced concrete frame structure building has become the mainstream form of architecture in our country. [0003] For frame structure buildings, using wall panels (including external wall panels and internal partition wall panels) as the wall is the direction of future development. At present, the wall panels with relatively mature technology are lightweight interior partition wall panels (including lightweight household wall panels and lightweight compartment wall panels, referred to as "lightweight partition wall panels"). The use of lightweight partition boards not only embodies the characteristics of the times of people-oriented, advancing with the times, and continuously improving people's working, living, and living conditions, but also conforms to my coun...
