Glass fiber reinforced plastic pipe and manufacturing method thereof

Abstract

The invention relates to a glass fiber reinforced plastic pipe and a manufacturing method thereof. Materials of the glass fiber reinforced plastic pipe comprise FW-H-2028 unsaturated polyester resin, HR-192-N unsaturated polyester resin, curing agent, accelerant, flame retardant, roving EDR240-T910, a non-alkali knitting mat MEK380, mesh cloth, a surface mat and a polyester thin film. The manufacturing method comprises weighing the two types of adequate unsaturated polyester resin, pouring the unsaturated polyester resin into different mixing buckets respectively and adding into the flame retardant and pigment paste in proportion; measuring the adequate accelerant and adding into the mixing buckets to be uniformly stirred; weighing a certain amount of curing agent to be mixed with the materials and uniformly stirring; manufacturing a lining in a corresponding mould and then manufacturing a structure layer; hoisting the mould to a curing station through a hoisting device to be heated and cured; hoisting the mould to a mould dismounting machine after the curing and performing demoulding through a mould dismounting ring. The production process of the glass fiber reinforced plastic pipe is simple, the materials are environmentally-friendly, and the damage to the physical health of people cannot be produced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a glass fiber reinforced plastic pipe and a manufacturing method thereof. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. According to the materials used to make pipes, they can be divided into metal pipes, plastic pipes and fiberglass pipes. Among them, the FRP pipe is a light, high-strength, corrosion-resistant non-metallic pipe. It is a glass fiber with a resin matrix weight. It is wound on the rotating mandrel layer by layer according to the process requirements, and spread evenly between the fibers The upper quartz sand is used as the sand layer. Its pipe wall structure is reasonable and advanced, which can give full play to the role of materials. Under the premise of satisfying the service strength, the rigidity is improved to ensure the stability and relia...

Problems solved by technology

[0003] The current FRP pipes are made of resin, glass fiber, and quartz sand as raw materials, and are made by a special process. The purification of the quartz sand needs to go through multiple steps such as scrubbing and desliming, magnetic separation, flotation, and acid leaching. The process is very troublesome. In addition, in the industrial production process of quartz sand, due to its extremely fine dust, it will have a great impact on the health of workers, and if inhaled for a long time, it may even cause lung cancer.
