Abstract

The invention discloses a creep-resistish long glass fiber, a creep-resistish long glass fiber enhanced propene polymer (PP) composite material and a preparation method thereof. The creep-resistish long glass fiber enhanced PP composite material has excellent impact resistance property and creep-resistish performance by adopting a special assistant and a compatilizer to reduce creeping problems and floating fibre problems, has smooth surface without floating fibers, is particularly suitable to prepare products such as vehicle parts, electronics components, instrument parts and aviation equipment parts and the like.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a creep-resistant long glass fiber, a creep-resistant long glass fiber reinforced PP composite material and a preparation method thereof. Background technique [0002] Long glass fiber reinforced pellets refer to pellets with fibers arranged in one direction, and the length of the fibers is equal to the length of the pellets, generally greater than 5mm. In China, research on long glass fibers is still in its infancy, and long glass fibers are generally used to improve the mechanical properties of polymer materials. Polypropylene resin (PP) is a general-purpose plastic with a wide range of uses. It is obtained by polymerization of propylene monomer. The advantages of polypropylene resin are low density, low price, excellent chemical corrosion resistance, good mechanical properties, Outstanding folding resistance and good formability. As a typical crystalline material, its melt...
