Problems solved by technology

The process of this material is simple and easy, and the product performance is good, but the composite material also does not add a light stabilizer or adopt an anti-ultraviolet aging method, and does not have anti-ultraviolet aging performance
[0008] Chinese invention patent CN101735513A discloses an alkali-free short fiber reinforced polypropylene composite material. The composite material has excellent mechanical properties. At the same time, the light stability performance is improved by adding a hindered amine light stabilizer. The antagonism between alkalis has not been completely resolved, so the anti-ultraviolet aging properties are limited

Abstract

The invention discloses an anti-ultraviolet aging glass fiber reinforced polypropylene composite material and a preparation method thereof. The composite material is composed of glass fiber reinforced polypropylene composite material particles and ASA at a mass ratio of 95:5-90:10; The fiber-reinforced polypropylene composite particle is composed of polypropylene, glass fiber, compatibilizer, antioxidant and light stabilizer. The material has strong anti-ultraviolet aging properties, and at the same time has the high strength and high toughness of the glass fiber reinforced polypropylene composite material; and the preparation process is simple, the production cost is low, and there is no secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to an anti-ultraviolet aging glass fiber reinforced polypropylene composite material and a preparation method thereof. Background technique [0002] Glass fiber reinforced plastic is a light-weight and high-strength engineering structural material. Because the fiber has good mechanical properties, when there is an external force, the load is transmitted through the fiber, so the tensile, bending, impact strength and resistance of glass fiber reinforced plastic Creep and fatigue resistance are far better than non-reinforced plastics, and have excellent rigidity, toughness, and warpage resistance, and their prices are much lower than engineering plastics. Glass fiber reinforced plastics are widely used, and about 50% of glass fiber reinforced plastics are used in the automotive industry in Western Europe. The performance of glass fiber reinforced plast...
