Description
Technical field
The present invention relates to the heat insulating material in a kind of band reflecting layer, can be used for building, industry, the insulation material in the field such as transportation.
Background technology
Along with expanding economy, the demand of the energy is increased by the whole world day by day, in the total energy consumption constantly increased, building energy consumption accounts for the 11%～25% of total energy consumption, therefore, Building Energy-saving causes the attention of increasing country, facts have proved, the most effective method of building energy conservation is to use heat preserving and insulating material, the most conventional heat-barrier material mainly has: foam glass, polystyrene foam plastics, glue powder polyphenyl granule insulating material, thermal insulation mortar, air entrained concrete, litaflex, composite silicate thermal insulation material etc., but first it typically have the disadvantages that, damping performance is poor, and oxidizable and corrosion, service life is short, within general 2 to three years, gradually lose waterproof, heat insulation function；Secondly, without air barrier in the middle of these Conventional insulation, interior outside energy easily forms thermal convection current and conduction of heat, thus affects effect of heat insulation.
The Chinese invention patent authorizing Publication No. CN1800293A proposes a kind of environment-friendly type cooling medium heat-insulating material; this material is by masterbatch; foaming agent, 2.5-dimethyl-2.5-double (tert-butyl peroxy base) alkynes-3, antioxidant, catalyst, magnesium silicate, HP-C molecular distillation monoglyceride, color masterbatch etc.; after dual-screw pelletizer prepares crosslinkable grafting master batch and antioxygen uncatalyzed master batch; again through the tubing of independent closed pore or the sheet material of foaming machine foam shaping by extrusion surface skining; cross-link through water environment, prepare environment-friendly type cooling medium heat-insulating material.Though this insulation material cost is low, heat insulation effect is more apparent, but complicated process of preparation, it is unfavorable for promoting the use of.
The Chinese invention patent authorizing Publication No. CN103466998A proposes a kind of Carbon aerogel thermal insulation material and preparation method thereof, this material is made up of manmade inorganic fibre, material with carbon element, dispersant and binding agent, wherein, the mass fraction of each component is: manmade inorganic fibre 100, material with carbon element 0-200, dispersant 0.5-2.0, binding agent 0.5-2.0.This material can be morphologically powder, can be slurry, it is also possible to be felt material or sheet material.Although this insulation material heat conductivity is little, can be used for building, industrial equipment and pipe insulation；But carbon aerogels is expensive, preparation cost is higher, is unfavorable for realizing industrialized production.
Heat-barrier material can be divided into by adiabatic principle: porous material, reflecting material and vacuum material three class, and the hole that the former utilizes material itself contained is heat insulation, because the heat conductivity of intrapore air or noble gas is the lowest, such as foamed materials, fibrous material etc..Heat-reflecting material has the highest reflection coefficient, heat can be reflected away, such as the polyester of gold, silver, nickel, aluminium foil or plating, Kapton etc., vacuum heat insulation materials is to utilize the inner vacuum of material to reach to intercept convection current to come heat insulation, from above-mentioned granted patent, we it is found that wherein porous material be widely used on heat insulating work, but the application that reflecting material is in engineering practice is the most little.
In nature, the transmission of heat has conduction of heat, thermal convection current and three kinds of basic modes of heat radiation, external wall is no exception, when there being occluded air interbed, what in three kinds of heat transfer types, heat output was maximum is heat radiation, account for the 70% of total amount of conducting heat, secondly 20% is accounted for for convection current, conduction of heat minimum only accounts for 10%, we have no reason the mentality of designing of outside wall heat preservation to be confined to stop in the such a narrow field of conduction of heat, it should heat radiation this principal contradiction maximum for heat output considers and solve problem.
Present situation based on current architecture exterior wall insulating materials and problem, the present invention devises the heat insulating material in a kind of band reflecting layer, fully utilize porous heat-insulating principle and reflective insulation principle, it is proposed that a kind of heat-insulating property is more excellent, the heat insulating material of low production cost.
