Abstract

The invention provides a glass fiber fabric reinforced polypropylene composite material as well as a preparation method and application thereof. The glass fiber fabric reinforced polypropylene composite material comprises 40-60 parts of glass fiber fabrics, 30-50 parts of polypropylene, 6-9 parts of a compatibilizer, 0.8-1 part of a light stabilizer and 0.3-0.6 part of an antioxidant. When appliedas a cover plate of an inspection well, the glass fiber fabric reinforced polypropylene composite material with less mass can be conveniently mounted, picked and placed by an operator; besides, the glass fiber fabric reinforced polypropylene composite material has the advantages of corrosion resistance, safety and environmental friendliness, can be recycled and is relatively low in cost.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a glass fiber cloth reinforced polypropylene composite material and a preparation method and application thereof. Background technique [0002] Polypropylene composite materials have good mechanical properties and corrosion resistance, so they have a wide range of applications and can be used as inspection well covers. Inspection manhole covers are generally installed at the intersection, turning, pipe diameter or slope change, drop water, etc. of drainage pipes in building areas (residential areas, public building areas, factory areas, etc.). In order to facilitate regular inspection, cleaning and dredging, usually use Buildings made of brick or cast iron are heavy and difficult to install and dismantle; in addition, their surfaces lack constant temperature and are very hot, which brings certain dangers to schools, shopping centers and other public spaces...
