The industries such as vehicle, electrical equipment and partial all kinds of cold and hot medium pipelines, container, the effect for reducing cold damage and heat waste can be reached, therefore
It is a kind of cross-centennial heat-insulating material of new generation of high-quality.When the seventies and eighties in last century, developed countries are
Through there is the precedent that insulating rubber plastic is applied to building field, paid attention to extensively particularly in terms of building energy conservation, and obtain
Huge achievement, these national building energy consumptions significantly decline；After insulating rubber plastic having been used such as Denmark, 1985 years ratios
Heating area in 1972 adds 30%, but heating energy consumption reduces 3,180,000 tons of standard coals, embodies significant social benefit
And economic benefit.
From the material and kind of building insulating rubber plastic, both at home and abroad to the rubber and plastic using polystyrene as primary raw material
Insulation material research 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 heat insulation effect in use as insulating rubber plastic, by
It is to be fixed as leading, supplemented by the fixation of face to put when the characteristics of sheet material make it that styrofoam couples in construction with main body, between sheet material
Carry out necessary splicing, cohere, be not suitable with insulation of the profile compared with complex building, construction technology is more complicated, integrated cost is high.Together
When, because the hydrophobicity of styrofoam and the hydrophilic material of routine are not suitable with, cause subsequent construction quality beyond its surface layer not
Easily 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, coating
Using or construction constitute very big restriction.As the application of rubber-plastic foamed insulation material is more and more wider, people not only meet
In its thermal conductivity factor is low, save space, thin materials the advantages that, some life application fields its anti-microbial property is proposed it is higher will
Ask, but existing rubber-plastic foamed insulation material is poor in terms of antibiotic property.
