Description
Technical field
The invention belongs to building material field, more particularly to one kind to avoid ground polymers-starch foam caused by lamination
The preparation method of particle composite thermal insulation material.
Background technology
According to the analysis of science and technology department of the Ministry of Construction, in the 30000000000 square metres of house architectural areas increased newly to the year two thousand twenty bottom, the whole nation,
City is newly-increased 13,000,000,000 square metres.If these buildings all realize 50% energy-conservation on the basis of existing, can about save every year
Save 1.6 hundred million tons of standard coals.In more than 400 hundred million square metres of existing building, the urban architecture gross area is about 13,800,000,000 square metres of left sides
The right side, the problems such as in the prevalence of building enclosure heat insulation property and low poor air-tightness heat-supply metering charge efficiency, energy-saving potential
It is huge.
At present, there is 40% energy resource consumption in building field, and exist in the energy resource consumption that building field has more than 60%
On skin, exemplified by accounting for the residential housing of China's urban architecture gross area about 60%, heating districts town-property area
There are about 4,000,000,000 square metres, the Heating Season average energy consumption of 2000 be about 25 kilograms of mark coals/square metre, if real on the basis of existing
Existing 50% energy-conservation, then it is annual about to save 0.5 hundred million tons of mark coals.As can be seen here, skin heat preservation energy-saving is in whole state
Shared proportion is very considerable in people's economy, it is necessary to attracts great attention.
With attention of the country to Building Energy-saving, building external wall energy-saving insulation industry increasingly attracts attention.It is external
Detection show, 50% is accounted for by the heat loss of wall facade in peripheral structure, and this domestic ratio is 46%, based on exterior wall
The important function that external thermal insulation has in building energy conservation, to implement this target, various regions building heat preservation work from now on will surround
Exterior-wall heat insulation deploys.The demand of the insulation material of estimated China of internal authority market analysis mechanism will increase with annual 9%
Rate develops, and is up to 28.4 hundred million RMB within 2011.It can be seen that whole building exterior-wall heat insulation industry has welcome unprecedented machine
Meet.
Be presently used for wall heat insulation material most study is organic insulation material system and inorganic heat insulation material system.
But (polystyrene type) the material high insulating effect of organic insulation at present, but easily triggering fire, smoke is big, and toxicity is big；And
Although inorganic material fire resistance rating is high, heat insulation effect is poor.
