Description
Technical field
The present invention relates to a kind of lagging material, particularly a kind of modified expanded perlite warming plate and preparation method thereof.
Background technology
Since the reform and opening-up, the fast development of China's economy improves constantly to industriallization and living standards of the people, and is increasing to the consumption of oil, coal equal energy source, thereby to the energy-conservation requirements at the higher level that proposed.In the total energy consumption of China, building energy consumption account is more than 30%, is one of the main aspect of the energy consumption of China.Relevant data shows, China newly-increased nearly 2,000,000,000 m2 of building construction area in annual town and country wherein are the highly energy-consuming building more than 85%; Nearly 42,000,000,000 m2 of existing building, about 95% is the high energy consumption building.The annual power consumption 4000 of whole nation buildings～5,000 hundred million degree accounts for 22%～24% of China's generated energy, and the floor area of building power consumption 26～27kWh/ of unit (m2a) is 2～3 times of developed country.
The overwhelming majority of building energy consumption is used to heating and air conditioner refrigerating.Along with the progressively raising of the home penetration rate of heating and air conditioner facility, corresponding building energy consumption also will significantly increase, and proportion also must be increasing in total energy consumption for building energy consumption.Buildings is divided into body of wall and door and window two parts, and wherein wall area accounts for more than 50%.The construction wall thermal conductivity is high, and heat conducts exchange with balance chamber's internal and external temperature through it, is the control room temp, must increase the weight of the burden of indoor heating and refrigeration equipment, causes energy dissipation.
For save energy, reduce thermal exchange through body of wall, the most feasible efficient manner is at exterior wall outside suspension thermal insulation system at present.The lagging material that this system adopted is the low density loose porous material, and its inner filling and closed air play very big barrier effect to the convection current of heat with conduction, thereby realize the purpose of heat preservation energy-saving.Can be divided into inorganic and organic insulation material according to the different lagging materials of material.Inorganic heat insulation material is main with rock wool, glass wool and pearlstone, is the lagging material that grows up at first.Inorganic heat insulation material acid and alkali-resistance, corrosion-resistant, stability height; Easy construction; Applied widely; Be applicable to the insulation of the complicated body of wall of various body of wall basic unit's materials and different shape, and its fire protection flame retarding security is good, can be widely used in intensive dwelling house, public building, large-scale public place, inflammable and explosive place, the strict place of fire protection requirement.Yet the heat-insulating property of inorganic heat insulation material is relatively poor, and impact resistance and compressive strength are poor, and water absorbability is big, has restricted its range of application.Organic type of lagging material has polystyrene block EPS, extruded polystyrene board XPS, granular polystyrene, spraying polyurethane SPU and polyurethane PU to hard bubble etc.That organic insulation material has is in light weight, processability good, compactness good, the characteristics of good effect of heat insulation.But there is disaster hidden-trouble in it, produces a large amount of dense smokes during burning, is prone to cause loss of life and personal injury.Although organic insulation material such as polystyrene foam and hard polyurethane foam has problems aspect fire savety, its good thermal and insulating performance, superior price advantage and the utilisation technology of comparative maturity still have market widely in China.China is the quite a long period flammable organic insulation material that will extensively adopt at present and even from now on; Dependence increases substantially its flame retardant resistance index, and to seek preferably resistance to flame can feasibility lower; This be because: significantly improve flame retardant properties and will inevitably increase material cost and technical requirements greatly, and then influence its popularization; Fire-retardant and be not equal to and do not fire, under the bigger situation of the intensity of a fire, the fire-retardant finish material still can be lighted, and fire retardant self burning also possibly produce a large amount of toxic smog, and the escape personnel dies like a rat or damped possibility when increasing fire and taking place.From the overall situation of building energy conservation and the special national conditions of China, organic insulation material in short duration also not preferably substitute can select for use, therefore, research and develop novel difficult fire or do not fire lagging material just become the current practical problems of needing solution badly with heat-insulation system.
From the angle consideration of difficulty combustion or uninflammability ability, inorganic materials is best selection.The main drawback of inorganic heat insulation material is that impact resistance and compressive strength are poor at present, and water absorbability is big.Through selecting suitable inorganic heat insulation material, sticker and hydrophobic function property powder, and carry out the scientific formula design according to application and can improve above-mentioned two big shortcomings.
