Abstract

The invention discloses a glass fiber reinforcement polypropylene composite material and a preparation method thereof. The glass fiber reinforcement polypropylene composite material is prepared from,by weight, 1-20 parts of molecular sieves modified by a silane coupling agent, 30-70 parts of polypropylene, 25-70 parts of glass fibers, 3-15 parts of a compatilizer, 0.1-3 parts of an antioxidant and 1-5 parts of a light stabilizer. According to the glass fiber reinforcement polypropylene composite material, the molecular sieves modified by the silane coupling agent of a porous structure are adopted and mingled with a semi-finished product, namely a glass fiber reinforcement polypropylene composite material for replacing traditional fillers such as calcium carbonate and mica powder, so thatthe mechanical performance of the glass fiber reinforcement polypropylene composite material is improved, the glass fiber reinforcement polypropylene composite material has high stretching strength, high bending strength and high impact-resistance strength, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of polymer materials, and specifically relates to a glass fiber reinforced polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene thermoplastic materials are widely used in various industries due to their cheap price, good formability, convenient processing and easy recycling and reuse. However, as the scope of application becomes wider and wider, the deficiencies in strength, impact resistance and high and low temperature resistance gradually appear, making it difficult to meet the requirements of high-performance products. The strength, modulus, impact resistance and high and low temperature resistance of the glass fiber reinforced polypropylene composite material have been greatly improved, so the glass fiber reinforced polypropylene composite material is more and more used to replace the traditional polypropylene material. [0003] Existing glass fiber rein...
