The characteristics of polyurea material

Hebei polyurea fender Editor told you The characteristics of polyurea material


  Polyurea is amino compounds by isocyanate component and component of an elastomer material. Divided into pure polyurea and half polyurea, their performance is different, the most basic characteristic of polyurea is anticorrosive, waterproof, wear-resisting, etc.



  Generated by reaction with amino compounds isocyanate component class of compounds. Isocyanate component can be a monomer, polymer and isocyanate derivatives, prepolymer and half prepolymer.


  Polyurea polymerization can be made of diisocyanate and diamine or urea.


  Polyurethane urea nonyl is representative of polyurea macromolecule. By condensation with urea, preparation of azelaic amine, its nature and polyamide (nylon 6) are similar, can melt spinning, melt temperature of 230 ℃ ~ 235 ℃, density is small (1.066 g/cm 3), good heat resistance, dyeing and corrosion resistance, fiber tensile strength is 0.0441 ~ 0.0539 n/denier, elongation is 23%, suitable for manufacturing nets and knitwear.


  Do not contain catalyst, fast curing, can be in any surface, slope and vertical spraying forming, do not produce flow phenomenon, 5 seconds gel, 1 minutes to walk.


  Is not sensitive to moisture, temperature, construction is not affected by environmental temperature, humidity, can be in - 28 ℃ under construction; on the ice coating curing).


  Two-component, 100% solid content, do not contain any volatile organic compounds (VOC), environmentally friendly, pollution-free construction, construction of health harmless to use.


  Thermal spraying or pouring, a construction thickness range from several hundred microns to a few centimeters, overcome the disadvantages of previous repeated construction.


  Excellent physical and chemical properties, high tensile impact strength, flexibility, abrasion resistance, prevent slippery, ageing resistance, corrosion resistance.


  With good thermal stability, can be long-term use under 120 ℃, 350 ℃ can withstand short-term thermal shock.


  Base, good reproducibility, continuous, dense coating, no juncture, pinhole, beautiful and practical and durable.


  The use of complete sets of equipment construction, high efficiency; A construction thickness can meet the design requirements, the equipment is equipped with a variety of switch mode, can spray already, also can hang water. And can be controlled by the construction worker skill to prevent slippery effect.


  Good cohesive force, can be in any such as steel, wood, concrete spraying forming on the substrate.
