Description
Technical field
The present invention relates to anti-flaming polypropylene material technical fields, and in particular to a kind of function additive is compounded with nano-oxide
Cooperative flame retardant polypropylene material.
Background technique
Polypropylene is a kind of thermoplastic resin as prepared by propylene polymerization.Polypropylene have it is nontoxic, tasteless, density is small,
The advantages of intensity, rigidity, hardness heat resistance are superior to low pressure polyethylene can use at 100 DEG C or so.With good dielectricity
It can and high-frequency insulation and not influenced by humidity, but become fragile when low temperature, it is not wear-resisting, easy to aging.Suitable for production common mechanical part,
Corrosion-resistant part and insulating part.The organic solvents such as common acid, alkali almost do not work to it, can also be used for tableware.
But while polypropylene also have the shortcomings that it is corresponding: product cold resistance is poor, and low temperature impact strength is low, product exists
In use vulnerable to light, heat and oxygen effect and the disadvantages of aging, easy firing；Since the presence of disadvantages mentioned above seriously constrains poly- second
Alkene material expands its use scope.
