Abstract

The invention discloses a glass fiber-reinforced plastic polyurethane TPU composite tube. The glass fiber-reinforced plastic polyurethane TPU composite tube comprises an outer protective layer, an outer reinforcing layer, a sand inclusion structure layer, an inner reinforcing layer and a lining layer which are sequentially arranged from outside to inside, wherein the outer protective layer is a composite layer with quartz sand and unsaturated polyester resin, the outer reinforcing layer is a composite layer with glass fibers and unsaturated polyester resin, the sand inclusion structure layer is a composite layer with quartz sand, glass fibers and unsaturated polyester resin, the inner reinforcing layer is a composite layer with glass fibers and unsaturated polyester resin, and the lining layer is a low free nanometer polyester layer. The invention further discloses a manufacturing process of the glass fiber-reinforced plastic polyurethane TPU composite tube. The glass fiber-reinforced plastic polyurethane TPU composite tube has reliability, safety and economy, is mainly used for pulp conveying, bittern conveying, sea water desalination and corrosion-resistant and abrasion-resistant process pipelines, has the advantages of being light, high in strength, resistant to corrosion, high in abrasion resistance, long in service life, low in operation and maintenance cost and the like, and saves a large number of expenses for construction engineering.

Description

technical field [0001] The invention relates to a FRP polyurethane TPU composite pipe and a manufacturing process thereof. Background technique [0002] The water pipes used in existing waterworks mostly adopt metal pipes or common plastic pipes. Although metal pipes are relatively strong and durable, they are heavy, easy to corrode, rust, and scale, and the cost is relatively high. Poor performance, easy to break with extreme weather changes, long-term drinking is harmful to human body and other shortcomings. Therefore, the development of a pipeline with excellent performance and harmless to human body has become a technical problem to be solved urgently. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a FRP polyurethane TPU composite pipe. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technic...
