Description

Environment-friendly type building insulation material and preparation method thereof
Technical field
The invention belongs to building material field, be specifically related to a kind of environment-friendly type building insulation material and preparation method thereof.
Background technology
There is the most eurypalynous insulation material both at home and abroad.Classify by material, insulation material can be divided three classes: metal heat preservation material Material, organic insulation material, environment-friendly type building insulation material.The source of goods of metal heat preservation material still this material is little, and price is very Costliness, can greatly improve cost for the insulation material as building, it is impossible to be widely applied.Organic insulation material is easy to Burning, easily produces poisonous gas when high temperature, ageing-resistant, fire resistance is poor, and these shortcomings all limit organic insulation material Use widely.
Environment-friendly type building insulation material composition the most aging, have will not thermal expansion, cold events, cracking resistance, peel etc. good Good self-characteristic.Compared with general insulation material, there is oneself special performance superiority, be irreplaceable in construction material Performance characteristics, and cost is relatively low, can save lot of materials, cost of labor.But presently commercially available environment-friendly type building insulation material Generally there is the problem that the coefficient of heat conduction is big, cause substantial amounts of energy consumption.
Inorganic heat insulation material is concentrated mainly on glass cotton, rock wool, expanded perlite, micro-nano thermal insulation board etc. and has certain insulation The material of effect, it is possible to reach the fire prevention of A level.The production of rock wool is harmful, and workman also can be reluctant that the situation of construction occurs, and And cycle that rock wool is founded the factory is long, can produce the time taking around 2 years from founding the factory.The supply of domestic market rock wool is also now Do not reach the requirement of use.The weight of expanded perlite is big, and water absorption rate is high.The heat-insulating property of micro-nano thermal insulation board is conventional vacuum material 3~5 times of material, are usually used under hot environment, but expensive.Expanded perlite is extensive due to raw material sources, production facility letter Single, harmless, it is believed that afterwards can be as main materials'use.But, perlite fatal defects be water absorption very Strong material, this is the loose structure due to expanded perlite, and is the result of a kind of perforate, and has adsorptivity, makes sky Gas and water can free in and out, and after it soaks 25 hours in water, its water absorption rate returns to about 5 times of own wt, this One shortcoming will greatly affect the heat-insulating property of expanded perlite product and the permanent suitability, also can increase expanded perlite system The drying cost of product.
Summary of the invention
For solving the problem that the coefficient of heat conduction is big and absorbance is high that existing insulation material exists, the present invention proposes one Environment-friendly type building insulation material, this insulation material has that the coefficient of heat conduction is low, water absorption rate and comprcssive strength advantages of higher.
The technical scheme is that and be achieved in that:
