Problems solved by technology

[0003] However, the quality of the boards on the market is uneven at present. The high amount of cement and low strength of the concrete boards lead to poor hanging force of the boards, so that the boards will crack when they are not used for a long time.
In addition, the heavy weight and poor insulation effect of the board bring great inconvenience to the hoisting and use of the board

Abstract

The invention relates to the technical field of building materials, and discloses a lightweight thermal insulation board and a preparation method thereof. The lightweight thermal insulation board is composed of: 300-500 parts of auxiliary gelling material, 30-50 parts of activator, and 100 parts of modifier ~200 parts, 500~1200 parts of aggregate, 20~60 parts of thickener, 150~250 parts of water; among them, the chemical composition of the cementitious material is CaO+SiO 2 +Al 2 o 3 >80%; Modifier composition: 5~20 parts of titanium white slag, 25~40 parts of lithium slag, 20~40 parts of attapulgite, 20~50 parts of carbide slag, 5~15 parts of fluorite powder, 5 parts of zinc iron slag ~15 parts; aggregate composition: 10~30 parts of slag sand, 10~20 parts of pearlescent sand, 5~20 parts of closed-cell perlite, 30~75 parts of lightweight aggregate. The invention adopts a large amount of industrial wastes to prepare the lightweight thermal insulation board with low cement consumption, low bulk density, high strength and good thermal insulation effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a lightweight thermal insulation board and a preparation method thereof. Background technique [0002] With the rapid development of my country's construction industry and the improvement of building energy conservation awareness, people have put forward new and higher requirements for the quantity, variety, function and quality of wall materials. The emergence of large space, large column net, and large bay flexible partition technology in building structures has led to the development of wall materials from block products to plate products, from single walls to composite walls, and from heavy walls to light walls. Therefore, building panels are increasingly favored by the industry. [0003] However, the quality of the boards currently on the market is uneven. The high amount of cement and low strength of the concrete boards lead to poor hanging strength of the board...
