Description
Technical field
The invention belongs to technical field of polymer materials, more particularly, it relates to a kind of poly- ammonia of modified thermoplastic
Ester elastomer material.
Background technology
Polyurethane is the abbreviation of polyurethanes, is a kind of emerging macromolecule organic material, by isocyanate groups
A kind of macromolecular compound synthesized with hydroxy compounds generation sudden reaction.Nineteen thirty-seven Germany Otto, professor Bayer was sharp first
Polyurethane has been synthesized with isocyanate groups and polyol compound addition polymerization, has indicated the beginning of polyurethane industrial.In future
In 80 years, polyurethane industrial has obtained significant progress, polyurethane elastomer due to its excellent wearability, mechanical performance, return
The remarkable performance such as elasticity, weatherability, oil resistivity, inoxidizability and be widely used in the every aspect of our daily lifes,
Constantly influence and change our life.
With the fast development of China's economy, automobile industry is increasingly becoming one of pillar industry for promoting GDP.In automobile
On, polyurethane elastomer product shows its various performance incisively and vividly.Whether the instrument board of interior trim, backrest, peace
Full air bag etc., or car paint, the tire of outward appearance, even the car film of automobile, auto sound heat-barrier material etc. be unable to do without poly- ammonia
Ester articles.Under the overall situation of this promotion energy-saving and emission-reduction, a large amount of fuel oils that automobile can be not only improved using polyurethane product
Economy reduces the discharge of carbon dioxide, while the outstanding performance of polyurethane product can delay the cycle that auto parts are changed
So as to save resource.
Filling-modified polyurethane elastomer is that corresponding filler is added during synthesis of polyurethane elastomer, is improved
The performance of polyurethane elastomer, reduce production cost.The filling-modified of filler is applied widely in polyurethane industries among others, such as is had
Machine filler can be used for fluid sealant, polyurethane slurry, special elastic body, polyurethane foam plastics；Inorganic filler includes calcium carbonate
Kaolin, molecular sieve powder talcum powder, blanc fixe, glass fibre etc., for polyurethane sealant, soft polyurethane foam polyurethane
Elastomer, adhesive polyurethane coating etc..
In actual applications, the intensity of material is a very important index.Possessing the same of good mechanical performance
When, we, which also are intended to material, can other property, such as electrical and thermal conductivity and electromagnetic shielding etc..This is not only extended
The application field of elastomer based nano composite material, and the function of some products can be improved conscientiously.In the prior art to these
The research of Structure-Property Relationship functionally is not also a lot.Requirement of the simultaneously different functions to filler is different.Mechanicalness
Filler can be needed to be uniformly distributed as far as possible, electric conductivity then needs filler to form close network, and heat conductivility then wishes filler
The capacity of heat transmission itself is strong and has good compatibility with matrix.
Thermoplastic polyurethane bullet is greatly improved by carrying out thermoplastic elastic material preferably with cooperation in the present invention
