Description
Technical field
The present invention relates to a kind of TPO materials, and in particular to a kind of with the TPO material for inhaling wave energy.
Background technique
Thermoplastic elastomer (TPE) (TPE) is a kind of high resiliency with rubber, high-intensitive, high resilience, and has and can be molded
The material of the feature of processing.TPE has environment-protecting and non-poisonous safety, has a wide range of application, there is excellent coloring, soft-touch is weather-proof
Property, fatigue resistance and temperature tolerance, processing performance are superior, and without vulcanization, can be recycled reduces cost, both can be with quadric injection mould
Molding can also be separately formed with the basis materials coating and bonding such as PP, PE, PC, PS, ABS.Therefore, it is often used as in vapour
The effects of water on door and window cuts material, plays sealing, the water droplet on removal glass surface, water mist, dust and beauty.Alkene
It is hard segment and EPDM as the blend of soft chain segment that class TPE system, which is using PP, abbreviation TPO.Due to its light specific gravity than other TPE
(only 0.88), heat resistance are up to 100 DEG C, resistance to weather and ozone resistance might as well, thus become another in TPE and have developed rapidly
Kind.But although simple TPO has many excellent performances, with the raising that people require material multifunctionality, TPO
The requirement of people is not reached still at many aspects, this is badly in need of us and develops a kind of multi-functional class as having and inhaled wave energy
TPO material.
In recent years, with the development of science and technology, a large amount of electronic equipment enters daily life, and electromagnetic radiation pollution is increasingly
Seriously.The electromagnetic environment of deterioration can not only interfere the normal work of electronic instrument, equipment, but also will affect the health of the mankind.Army
In thing, the international competition of weaponry is growing more intense, due to the rapid development of modern Detection Techniques and precision guided weapon, to force
The existence of device causes great threat, therefore studies the stealthy imperative of weapon.And absorbing material is exactly military stealthy, micro-
The defence and militaries such as wave darkroom, microwave communication, electromagnetic information leakage protection, electromagnetic interference shielding, electromagnetic radiation protection and civilian skill
One of critical material in art field, the especially development of electromagnetic shielding, stealth technology in recent years, make the research of absorbing material increasingly
Paid attention to by people.Ideal absorbing material should have that wide absorption band, light weight, thickness are thin, physical and mechanical property is good, make
The features such as with simplicity.The present invention makes TPO material obtained have electromagnetic wave absorption by adding absorbing material in TPO material
Function, to significantly increase the application of TPO material.It such as applies in building field, is absorbed and radiated by this TPO material
Electromagnetic wave, the phenomenon that greatly reducing Contamination of Electromagnetic Wave, alleviate electromagnetic interference.
Summary of the invention
Goal of the invention of the invention be to provide it is a kind of can facilitate it is molding, have and inhale wave energy and will not influence molding matter
The TPO material of amount.
Of the invention being achieved in that with the TPO material for inhaling wave energy is calculated in parts by weight, comprising:

Absorbing material has conducting polymer, nano material, chiral material, retinyl Schiff's base etc..In addition, the absorbing material being added can also
To be the mixture of two of them kind or many kinds of substance.
3, inorganic filler: be added inorganic filler, can be further improved mechanical performance, heat resistance, dimensional stability and
Economy requires that different amounts, different types of inorganic filler is added according to client's difference.Under normal circumstances, inorganic filler can
To be the mixture of one of calcium carbonate, titanium dioxide, talcum powder, silica, potassium carbonate, kaolin or at least two.
A small amount of inorganic filler can also play the role of nucleating agent, and polyacrylic irradiation stability can be improved in the addition of nucleating agent, can
To be effectively reduced the degree of polymer degradation.
4, fire retardant: Environmental Factors are considered, use aluminum diethylphosphinate ADP or melamine polyphosphoric acid in the present invention
Salt MPP or two kinds of mixtures do fire retardant.
Each raw material is weighed in proportion, is premixed 5~10 minutes, is placed into double screw extruder in high speed mixing smelting machine,
Melting extrusion is granulated at 80~180 DEG C.
Compared with prior art, the present invention having the following beneficial effects:
(1) TPO material that the formula is prepared through the invention has the function of electromagnetic wave absorption, can be effective
Reduce electromagnetic radiation.
(2) TPO material obtained joined fire retardant and inorganic filler through the invention, and material can be made to have suction
While wave energy, other properties are also able to maintain excellent.
