Description
Technical field
The present invention relates to field of modified polypropylene composite materials, a kind of especially high-modulus high tenacity talc poly- third
Alkene composite material and preparation method.
Background technology
Talcum powder is a kind of hydrosilicate, and chemical formula is 3MgO4SiO2H2O, and crystal form can be sheet,
Lobate, needle-shaped or blocky, the structure of pure talc, which is sandwiched in by one layer of shepardite between two layers of silica, to be constituted, and interlayer is folded each other
Add, adjacent talcum layer relies on weak Van der Waals force and combines, when applying shear action to it, it is easy to the relatively sliding of interlayer occur
It is dynamic.When the Van der Waals force between talcum powder is destroyed, generation splitting advantageously forms the composite material of part nanostructure,
To improve the performance of material.
Different talcum powder is different on the influence of the performance of PP/ elastomers/talc system, in general, low mesh
Several talc PP systems, notched impact properties is low, and bending modulus is low, with the reduction of talcum powder grain size, the machine of material
Tool performance is gradually increasing, until superfine talcum powder, reaches 10000 mesh or more.Talcum powder is easy to reunite because grain size is too small, locates
It manages bad, is present in composite talcum powder filled material of polypropylene as defect instead, decline so as to cause the mechanical property of materials.
