Description
Technical field
The invention belongs to the technical field of modification of polymer composite, and in particular to a kind of fibre-reinforced polypropylene material
Material and preparation method thereof.
Background technique
Polypropylene (PP) is a kind of thermoplastic resin of function admirable, has many advantages, such as cost performance is high, easy to process,
It is all widely used in fields such as automobile, household electrical appliances, but is used as engineering plastics at present, in intensity, rigidity, conduction, led
Heat etc. Shortcomings require to be further improved according to its application environment.Carbon fiber has small specific gravity, specific strength and ratio
The features such as modulus is high, corrosion-resistant, is the most important reinforcement of advanced composite material.Carbon fibre reinforced composite has intensity
The advantages that high, light-weight, high temperature resistant, high heat resistance, research prepare high-performance carbon fibre reinforced polypropylene compound material, to meet
Automotive field requires highly important economic value and social effect to material lightweight.In addition, polyacrylic thermally conductive
Performance is poor, as long as thermal conductivity 0.19W/ (mk), when being applied to chemical industry heat exchanger, electronic radiation equipment, it is necessary to mention
Its high heating conduction is to meet the field that these have higher requirements to thermal conductivity.Therefore, it is multiple to study high-intensitive high thermal conductivity polypropylene
Condensation material is of great significance with meeting the fields such as automobile, machinery, chemical industry, electronics to the needs of functional composite material.
