Send out important.The building energy consumption of China accounts for the 27% of national energy aggregate consumption, occupies first of national all kinds of energy consumptions.
The energy consumption of heating and air-conditioning accounts for the 55% of building total energy consumption, but also increases in the speed with annual 1 percentage point.
Because a little, research and develop insulating mold coating for construction and there is great economic benefit, environmental benefit and social benefit.Make in external wall
The original decoration of coating, protection and the function such as mould proof not only can be realized with the coating with heat insulating function, but also make coating
There is heat-insulated function, keep indoor temperature constant, increase the temperature difference of indoor and outdoor, warm energy consumption is reduced in summer, reduced in the winter time
Heat cost.At present, heat-barrier material is just experiencing the transformation to based on heat-insulating heat-insulated from industry, and this is also heat-insulated material from now on
One of main development direction of material.Insulating moulding coating has the disadvantage that in the market：
1st, poor insulation property：The density of glass microballoon or ceramic fine bead is high with respect to borosilicate hollow glass micropearl, thus in phase
With adding under consumption, the coating acquisition dry film heat insultating cavity using glass microballoon or ceramic fine bead is few, and coating thickness is relatively low, adiabatic
Poor performance；
2nd, poor storage stability：Glass microballoon or ceramic fine bead etc. are through surface treatment and density is relatively low, make coating in storage
During easily produce viscosity increase and the phenomenon for floating；
3rd, construct inconvenient：Using glass microballoon or the insulating moulding coating of ceramic fine bead, in order to prevent that floated during storing to show
As, the usual initial viscosity for improving coating, thus higher paint film can only be obtained by the way of blade coating or batch painting during construction
Thickness.
