Inorganic fiber reinforced cement heat preservation product

Abstract

The invention discloses an inorganic fiber reinforced cement heat preservation product. The heat preservation product comprises a liquid material and a powder material, and when the heat preservation product is used, the liquid material and the powder material are prepared into a finished product according to the weight ratio of 1: 1, wherein the powder material comprises the following raw materials in percentage by weight: 40%-68% of cement, 15%-25% of filler, 15%-25% of light aggregate and 0.5%-2% of an early strength agent; and the powder material comprises the following raw materials in percentage by weight: 1%-1.5% of foaming agent, 0.5%-1% of foam stabilizing agent, 0.5%-1.5% of toughener, 0.5%-2.5% of hydrophobic agent and the balance water. Experiments prove that, the addition of inorganic fiber can effectively improve the creasing resistance of the product and increase the toughness and the dimension stability of the product, and various indexes can meet the existing related national standards.

Description

technical field [0001] The invention belongs to the field of new building thermal insulation materials and resource recycling, and in particular relates to an inorganic fiber reinforced cement thermal insulation product. Background technique [0002] In the 21st century, energy conservation has become my country's third basic national policy after family planning and environmental protection, and is one of the fundamental requirements for building a conservation-oriented society. At present, the increase of building energy consumption in my country accounts for 27.8% of the total energy consumption. With the rapid development of the national economy, the rising trend of building energy consumption in my country is accelerating year by year. Therefore, actual building energy conservation has great significance and potential for my country's energy strategy. [0003] Energy-saving buildings are far superior to traditional buildings in terms of reducing building energy consump...

Problems solved by technology

[0007] Existing rigid porous inorganic thermal insulation materials, such as silicon-calcium board, hard silicate board, magnesite foam board, due to the limitations of their formula and technical process, most of the material products have a single structure, unstable, and pore-forming Unevenness, low porosity, high thermal conductivity, low strength, poor flexibility, poor sound insulation and absorption performance, fragile and easy to damage, etc., directly affect the promotion and use of materials, and its practical application effect is not ideal

Other inorganic thermal insulation materials that have appeared on the market in the past one or two years all have immature technology, unqualified actual testing, etc., and their comprehensive performance is low.
