Description
Technical field
The invention belongs to technical field of material chemistry, is related to a kind of insulation material, and specially a kind of modified glue powder granular polystyrene is protected
Adiabator and preparation method thereof.
Background technology
With the fast development of modern industrial civilization, the natural resources such as oil, coal, natural gas is largely consumed, the energy
Has there is relatively nervous situation in supply, and first time world oil crisis cause ballooning oil prices within 1973, now,
The whole world common concern energy problem, and be classified as one of four major problem for influenceing human survival.According to statistics, it is for building
The 1/3 of the whole world consumption energy can be accounted for, while energy for building, a large amount of pollutant CO are discharged to air2、TSP、SO2, NOx etc.
Sour gas causes the excess emissions of the acid rain of large area, greenhouse gases to cause global warming, will jeopardize the mankind and biology
Boundary is survived, and under such historical background, Building Energy-saving is formally proposed, and is gradually paid attention to by countries in the world and regarded weight
Big problem is studied.
To today, it refers in the case where not influenceing the precondition of people's degree of being comfortable on (i.e. the concept development of building energy conservation
Inhabitation room temperature winter is not less than 18 DEG C, and summer is not higher than 26 DEG C), take active and effective measure reasonably to use between floors
The energy, the energy is effectively utilized, so as to improve the energy utilization rate of building.Energetically adopt various measures and promote building energy conservation
