Description
Technical field
The present invention relates to building thermal-insulation energy-saving field, be specifically related to a kind of heat insulating inner wall basic unit's cream and preparation and application.
Background technology
Based on the national conditions of resource anxiety, environmental carrying capacity weakness.Along with socioeconomic fast development, heat preservation energy-saving has become the focus of whole society's growing interest.In recent years since, the environmental problem that Global warming causes is very outstanding, the each state in the whole world all recognizes if do not strengthen the control to energy consumption, since growing this, going from bad to worse of environment for human survival will be caused, finally bring extinction to human society, building energy consumption accounts for 30% of the whole society of China total energy consumption, and country has gone out a series of policies for building thermal-insulation energy-saving.
At present more feasible heat insulating inner wall product, substantially in space state, is mainly that construction cost and product cost are too high.Replace conventional putty with heat preservation putty, in the situation that substantially not increasing cost, increased the heat insulation effect of body of wall, of far-reaching significance for building energy conservation heat insulation.
Also some heat insulating inner wall putties that occurred on market, the disadvantage of existence is a lot, is difficult to be accepted by market.The essential substance that heat insulating inner wall putty plays heat insulation effect is inner wall putty heat-insulating powder, and the addition of inner wall putty heat-insulating powder and its specific physical character affect heat insulation effect and the physical property of heat insulating inner wall putty.Most of inner wall putty heat-insulating powder are hollow structure, and physical strength is poor, easily water-absorbent.Putty layer poor water resistance, insufficient strength, shortcoming that snappiness is not all right etc., often appear that application property is difficult for, in putty prepared by single untreated putty heat-insulating powder.If reduce the interpolation of putty heat-insulating powder, these shortcomings make moderate progress, but the heat insulation effect variation of while heat preservation putty.Due to these shortcomings, make original heat insulating inner wall putty more difficult acceptance and widespread use on market.
