A comparative analysis of the insulation materials on the roof of the building

Building roof roof insulation materials, the use of a wide range of areas, can be used in the external wall insulation project, can also be used in the external wall insulation project. The insulation body of the insulation material of the plate can be foaming polystyrene plate, extruded polystyrene plate, rock wool plate, glass cotton plate and other different materials.
Building roof roof insulation materials should have good waterproof, freeze-resistant, weather-resistant, impact-resistant, air pressure-resistant: as the external wall insulation, thermal insulation coating engineers pointed out that its surface direct contact with the outside environment must resist rain, freezing, impact and strong wind and other adverse factors, so before use should test the above functions. The pull-resistant strength of the alkali-resistant glass fiber mesh cloth matching the external insulation insulation system should be greater than 200N/cm, the residual pull strength after alkali resistance should not be less than 150N/cm, the 7-day anti-pull bonding strength of the adhesive should be greater than 1Mpa, the water-resistant, freeze-resistant melting anti-pull bonding strength should be greater than 0.9Mpa.
1, expansion polybenzene plate (EPS board) thermal conductivity 0.038-0.041 thermal insulation effect is good,
cheap, not waterproof strength slightly worse;
3, building thermal reflection insulation coating ZS-221, high solar thermal reflectivity, good insulation effect, waterproof and moisture-proof, more convenient construction, winter effect is not much
;
5, glue polybenzene particle thermal conductivity coefficient 0.057-0.06 flame retardant good, waste recovery insulation insulation effect is not ideal, high construction requirements;
6, polyurethane foaming material thermal conductivity 0.025-0.028 waterproof, good insulation effect, high strength price
is more expensive; Building insulation coating ZS-211, low thermal conductivity, winter and summer insulation insulation effect is good, construction to paint a certain thickness, expensive;
8, pearl rock and other slurry thermal conductivity 0.07-0.09 good fire resistance, low heat insulation effect, high water absorption,
building roof roof insulation material, thermal reflection insulation coating can make the coating in the sun's rays to produce temperature regulation effect of the coating is called thermal reflection paint, reflecting the heat of sunlight, reduce the heat of the building body heat coating. Insulation coating engineers pointed out that solar thermal reflection coatings are mainly used for outdoor, from an environmental point of view, the base material is preferably water-based, its own without heat-absorbing groups, and comprehensive consideration of water resistance, soil resistance, weather resistance and other properties. The strength and weakness of reflecting sunlight is mainly indicated by the refring index of matter, and the larger the refring index, the stronger the reflective ability of human sunlight.
building roof roof insulation materials, the company carefully researched and developed the production of ZS-221 type sunscreen insulation coating and ZS-222 thermal reflection insulation coating, coating is a set of reflection, radiation and hollow microbead insulation and one New sun protection and cooling coatings, thermal reflectivity and hemmic emission rate are more than 90%, do not allow the sun's heat on the surface of the object to accumulate heat, but also automatically heat radiation cooling, the surface of the object heat radiation into space, reduce the temperature of the object, even on cloudy days And night ZS-221 type sunscreen insulation coatings and ZS-222 thermal reflection insulation coatings can also radiate heat to reduce the temperature, while in the sun insulation energy-saving coatings with very low thermal conductivity hollow microbead insulation energy Transmission, even when the atmospheric temperature is very high, can be separated from external heat to the internal conduction of objects, so that ZS-221 type of sunscreen insulation coating three effects to ensure that the coating of the object cooling, to ensure that the internal space of the object can maintain a lasting state of indoor temperature, Long-term keep the building indoor cool and comfortable, restore a fresh natural green space temperature.
building roof roof insulation materials with technology to build products, new materials and new technology applications, ZS-221 type sunscreen insulation coating and ZS-222 thermal reflection insulation coating can reduce the surface temperature of the object by more than 20 degrees C, the internal space of the object can be reduced by more than 5 degrees C, in the absence of sunlight, cloudy days and nights can be cooled by more than 3 degrees C or reduced to atmospheric temperature consistent. Insulation coating has a good waterproof and leak-proof effect on objects coated with small cracks. In addition, the paint brush smooth and flat, hydrophobic, self-cleaning performance is good, so ZS-221 type sunscreen insulation coating and ZS-222 thermal reflection insulation coating is an efficient sun protection and cooling thin layer, decoration self-cleaning, waterproof moisture, anti-UV aging, acid-base anti-corrosion in one of the new anti-sun insulation energy-saving long-life coating.
