Description
Technical field
The invention belongs to field of heat insulating materials, more particularly to a kind of halogen-free rubber-plastic foamed insulation material and its preparation side
Method.
Background technology
Traditional heat preserving and insulating material is to improve gas phase voidage, is reduced based on thermal conductivity factor and the coefficient of conductivity.Fiber
In use environment convection heat transfer' heat-transfer by convection and radiant heat transfer will raise class insulation material, it is necessary to have thicker coating；And section bar class
Inorganic heat insulation material will carry out assembling construction, there is that seam is more, damages the defects of attractive in appearance, water proofing property is poor, service life is short.Rubber and plastic
It is the influence factor for influenceing building energy conservation that the promulgation of insulation material and product, energy-saving act, which performs, is related to a huge industry
The development of colony building insulating rubber plastics is with application increasingly by the most attention of countries in the world, novel rubber plastic thermal insulating material
Material constantly emerges in large numbers.From the material and kind of building insulating rubber plastic, both at home and abroad to being main using polystyrene
The insulating rubber plastic research of raw material is relatively extensive, but the overwhelming majority is all in sheet material field, such as styrofoam, steel wire net rack sandwich
Composite inside and outside wall plate, metal composite battenboard etc..Although styrofoam has good guarantor in use as insulating rubber plastic
Temp effect, but due to being to be fixed as main, face with point to be fixed as when the characteristics of sheet material make it that styrofoam couples in construction with main body
It is auxiliary, necessary splicing is carried out between sheet material, is cohered, is not suitable with insulation of the profile compared with complex building, construction technology is more complicated, comprehensive
Synthesize this height.Simultaneously as the hydrophilic material of the hydrophobicity of styrofoam and routine is not suitable with, cause follow-up beyond its surface layer
Construction quality is not easy to ensure, easily occur surface layer mortar ftracture, come off, the quality problems such as hollowing, to the external decoration of building such as
Face brick, the use of coating or construction constitute very big restriction.Unsetting slurry insulating rubber plastic can overcome sheet material class
These deficiencies, therefore it constitutes the important component of building heat preservation heat-barrier material.The developed countries such as America and Europe are in slurry rubber
The research and application aspect starting of modeling insulation material are more early, and technology is more ripe, upper fruitful in research and application.
Rubber-plastic foamed insulation material is a kind of new widely used heat-insulating heat-preserving material, has trickle independent closed pore
Structure, have the characteristics that density is small, thermal conductivity factor is low, do not absorb water, be flexible, be ageing-resistant, be corrosion-resistant, water proof, resistance vapour.Extensively should
For the position such as building, hotel, apartment roof, metope, central air-conditioning, building trade heat-insulating and sound-absorbing, shockproof.Meanwhile to understand
The problem of certainly its is inflammable, often through addition halogen based flame retardant to reach flame retardant effect, but the fire retardant of halogen makes
Easily environment is polluted during, is unfavorable for environmental protection and sustainable development.
The content of the invention
For drawbacks described above, it is an object of the invention to provide a kind of halogen-free rubber-plastic foamed insulation material and its preparation side
Method, effect of the halogen based flame retardant in foaming thermal-insulating is replaced with other compositions in preparation process, avoids halogen flame retardant
Agent pollution on the environment.
