Description
Technical field
The present invention relates to a kind of modified material technical fields, and in particular to a kind of for the PP alloy of plating and its preparation side
Method.
Background technique
Polypropylene (abbreviation PP) has excellent mechanical property, lower density, good heat resistance, excellent bending resistance
The advantages that bent fatigability, chemical stability and electrical property is one of maximum general-purpose plastics of dosage.But since polypropylene belongs to
Non-polar polymer, so that polyacrylic hydrophily, dyeability, antistatic property, cementability, impressionability are very poor, these disadvantages
Seriously limit polyacrylic application.
Plating is the technique developed rapidly in recent years, and the product after plating has good decoration function, and needs electricity now
The plastic product of plating can only almost select a kind of material of ABS, not be able to satisfy the power such as impact strength, tensile strength, elasticity modulus
It learns and requires, and cost is high.It sometimes for part strength is improved, is increased in size, but the following contraction distortion influences
Presentation quality.Though general PP polypropylene material is also able to satisfy high-intensitive mechanical property and cheap, plating layering, attached
Put forth effort very poor, cannot be received by market always.
Summary of the invention
The PP alloy and preparation method thereof that the object of the present invention is to provide a kind of for plating.
