A kind of building energy-saving material and its preparation process

Abstract

The invention discloses a building energy-saving material which is prepared from the following components in parts by weight: 25-40 parts of coal ash, 0.1-0.5 part of sodium hydroxide, 12-24 parts ofsodium silicate, 0.2-0.4 part of calcium stearate, 0.4-0.8 part of sodium dodecyl benzene sulfonate, 13-19 parts of a China hemp fiber, 6-15 parts of a shaping phase-change material, 5-15 parts of a short-cut carbon fiber, 3-7 parts of a sepiolite fabric, 10-22 parts of modified cellulose aerogel, 6-18 parts of a starch-based porous carbon material and 1-3 parts of talcum powder. The building energy-saving material disclosed by the invention is wide in raw material source, low in price, and non-toxic and harmless in the preparation and use process, and compared with a conventional inorganic heat-preservation material, the material is light in weight, low in water absorption rate, good in fire resistance, good in durability and good in heat-preservation effect and sound absorption effect, and further has a radiation resistance effect.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a building energy-saving material and a preparation process thereof. Background technique [0002] With the rapid development of economy and society, people's requirements for living comfort have increased, and building energy consumption has also become higher and higher, accounting for an increasing proportion of the country's total energy consumption. Rational use of energy and improvement of energy utilization have become research hotspots. Promoting the in-depth development of building energy-saving materials is of great significance to ensuring energy security, reducing greenhouse gas emissions, protecting the atmosphere and ecological environment, saving land resources, and improving people's living standards. Traditional inorganic thermal insulation materials have too heavy bulk density, high water absorption rate, and poor thermal insulation effect; new organic thermal...

AI Technical Summary

Problems solved by technology

Traditional inorganic thermal insulation materials have too heavy bulk density, high water absorption rate, and poor thermal insulation effect; new organic thermal insulation materials are light in weight, and their thermal insulation effect is better than inorganic thermal insulation materials, but their mechanical properties and fire resistance are poor, their sound insulation effect is not good, and their VOC content is high. , release a large amount of toxic gas when burning, poor safety
