Slip-casting inorganic insulation board and preparation method thereof

Abstract

The invention relates to a slip-casting inorganic insulation board and a preparation method thereof. The slip-casting inorganic insulation board comprises the following components in parts by weight: 500-600 parts of high-alumina cement, 100-200 parts of ordinary silicon cement, 100-200 parts of desulfurized gypsum, 300-450 parts of glazed hollow bead, 3 parts of hydroxypropyl methylcellulose, 1 part of 6mm-PP (Polypropylene) fiber, 8 parts of glass fiber, 4 parts of non-woven fiber, 4 parts of animal protein foaming agent and 1000 parts of water. The slip-casting inorganic insulation board has the advantages of high strength, difficulty in pulverization, low water absorption, stronger cohesive force with walls, difficulty in dropping, low heat conductivity coefficients, and very good energy-saving heat preservation effect, and therefore, the slip-casting inorganic insulation board simultaneously has two functions of fire retardancy and energy-saving heat preservation, thus buildings are safe and energy-saving and meet the requirements of energy conservation and environmental protection and green buildings.

Description

technical field [0001] The invention relates to a grouting-molded inorganic thermal insulation board and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] At present, there are many kinds of thermal insulation materials in my country's construction industry, which are mainly divided into organic thermal insulation materials and inorganic thermal insulation materials according to their chemical composition. Organic thermal insulation materials, due to complete sets of equipment, less investment, quick factory construction, light bulk density and low thermal conductivity, are very suitable for building thermal insulation, so they are developing rapidly. It can be said that organic thermal insulation materials have made great contributions to building energy conservation. However, organic thermal insulation materials are combustible and flammable materials, which are not resistant to high temperatures and soften ...

AI Technical Summary

Problems solved by technology

However, organic thermal insulation materials are combustible and flammable materials that are not resistant to high temperatures and soften at around 100°C. Burning quickly spreads on the combustible body. This kind of fire is difficult to achieve effective rescue and often causes serious economic losses and casualties.
