Description
Technical field
The invention belongs to technical field of polymer materials, relate to a kind of PP composite material and preparation method thereof and use
On the way.
Background technology
Other macromolecular material compared by polypropylene, and its electrical insulating property is good, and (sheet resistance is up to 1017Ω), light weight, resistance to punching
Hitting property is good, abrasion performance, heat conductivity are low, processing cost is low, is widely used in automotive upholstery, and principal item has: instrument board, door interior trim
Plate, central authorities box, steering wheel cover plate etc..But, its high-insulativity of polypropylene material as automotive upholstery is often rubbing
Can produce accumulation of static electricity during wiping, cause dust suction, may result in electric shock, discharge and even burn time serious, this just uses to automobile
Person's daily life brings a lot of trouble and potential hidden danger, and the antistatic of most automobile main frame maker to interior product has pointed out bright
Really requirement, generally individually requires that material surface resistance is less than 1013Ω.Therefore, plastic material and product thereof how are eliminated and reduce
Electrostatic hazard, it has also become current important technology problem.
Having multiple method to be used to reduce the resistance of plastic material at present, conventional is that surface processes and adds electric conductivity thing
Two kinds of methods of matter.The method of the previous interpolation electroconductive stuffing (such as white carbon black etc.) occurred due to exist product appearance and colour difference,
Material property reduces, high in cost of production shortcoming, the most less use.Most currently used method is exactly on internal or surface
Adding antistatic additive, this kind of method can effectively prevent electrostatic savings in the plastic, and can not change the original thing of goods
While property, its sheet resistance is controlled 1013Within Ω, thus give the antistatic property that goods are higher.
Mist degree refers to the organic substance volatilized from automotive interior plastic ornament and the material shape on glass being vaporized with
The condensation become.Particularly relating on weatherstrip window, when illuminating the best, atomization concretion may be to the intervisibility journey of weatherstrip window
Degree impacts.Additionally these harmful substances can also make people be poisoned unawares, is even equivalent to Chronic Suicide, the most more comes
The mist degree of material for car interior trim parts is required more and more stricter by the most automobile main frame maker.
At present automotive upholstery antistatic additive majority is little molecule or the little compound of molecular weight, its utilize this in
Animal migration in material matrix gradually moves to material surface to obtain stable antistatic property.If molecular weight is too big, then
Being difficult to move to material surface, antistatic effect is the best；If but molecular weight is the least, the most easily separated out, cause material mist degree
Bigger than normal.
Summary of the invention
Present invention aims to the defect of prior art and provide a kind of Antistatic low haze polypropylene material and
Preparation Method And The Use.The sheet resistance of polypropylene material can be controlled 10 by the present invention13Within Ω, and mist degree
Less than 3ug.
