Abstract
A large-diameter anti-static epoxy glass fiber reinforced plastic pipe belongs to the technical field of production of glass fiber reinforced plastic pipes. A carbon fiber felt conducting layer is disposed close to the inner wall of the pipe, a glass fiber high-strength yarn winding layer is disposed outside the carbon fiber felt conducting layer and is formed through helical and cross winding of epoxy-resin-soaked glass fiber high-strength yarns and carbon fiber yarns, both the outer wall and the inner wall of the pipe are covered with epoxy resin layers, and the anti-static high-strength epoxy glass fiber reinforced plastic pipe is obtained through high temperature solidification. The obtained pipe has a smooth inner wall, a high resin content, a neat and smooth appearance and excellent anti-static effects. At ambient temperatures from -40 DEG C to 120 DEG C, anti-static properties of the pipe, physical strength indexes of the materials, and decay resistance indexes of the pipe do not decline. Under ocean exposure conditions, anti-static, aging-resistant, and fatigue resistant service life of the pipe is no less than thirty years.
Description
Technical field
The invention belongs to the GRP pipe production technical field.
Background technique
This pipeline is mainly used in the field that fire prevention water system on offshore oil production platform and the boats and ships, Sprinkler system cargo oil handling system etc. have the pipeline antistatic to require.
Existing technology adopts epoxy resin, glass fibre, curing agent, antistatic material (Powdered) to be made into mixture in proportion, and is Wrapping formed on the pipeline mould, and curing process adopts the outer solidifying of baking box.The problem of coming that exists is to be mixed with conductive powder in the pipeline configuration, because raw material increases antistatic material, solidification process makes the conductive material skewness easily; Poor electric conductivity has reduced the conductive effect of pipeline, has reduced the intensity of pipeline simultaneously; Defect rate is high, and the pipeline fabricating cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of heavy caliber antistatic epoxy GRP pipe, low to solve the existing technology physical strength, defect rate is high, is prone to produce bubble, problems such as poor electric conductivity.
The utility model mainly is made up of pipeline outer wall, inner-walls of duct, glass fibre high strength yarns winding layer; Solving the technological scheme that its technical problem adopts is near inner-walls of duct the carbon fiber felt conductive layer to be set; Carbon fiber felt conductive layer skin is glass fibre high strength yarns and graphite fiber winding layer; It is Wrapping formed that glass fibre high strength yarns and graphite fiber yarn soak into rear screw through epoxy resin, the graphite fiber yarn structural distribution that in pipeline, assumes diamond in shape; Pipeline outer wall, inner-walls of duct all have epoxy resin layer to cover, and obtain antistatic high-strength epoxy GRP pipe through solidifying in the high temperature.
Adopt the good effect of the utility model to be:
1, this pipeline anti-static effect is remarkable, can Zai during 120 ℃ of Huan border Wen Du – 40 ℃----, and antistatic performance does not descend, and the physical strength index of material does not descend, and the rotproofness index does not reduce.
2, under the condition that this pipeline can expose in the ocean, antistatic, ageing-resistant, endurance were not less than 30 years working life.
3, inner wall smooth, resin content are high, flat appearance is smooth.
Description of drawings
Below in conjunction with accompanying drawing and instance the utility model is further specified:
Accompanying drawing 1 is the utility model structural representation;
1 graphite fiber, 2 glass fibre high strength yarns winding layers, 3 carbon fiber felt conductive layers, 4 pipeline outer walls, 5 inner-walls of duct among the figure.
Embodiment
As shown in the figure; Near inner-walls of duct 5 carbon fiber felt conductive layer 3 is set; Carbon fiber felt conductive layer 3 skins are glass fibre high strength yarns winding layer 2; Glass fibre high strength yarns and graphite fiber 1 soak into the rear screw intersection through epoxy resin and are wound on the pipeline mould; Graphite fiber 1 is embedded in the pipeline glass fibre high strength yarns winding layer 2 with the glass fibre high strength yarns, the graphite fiber 1 yarn structural distribution that in pipeline, assumes diamond in shape; Pipeline outer wall 4, inner-walls of duct 5 all have epoxy resin layer to cover, and obtain antistatic high-strength epoxy GRP pipe through hot setting.
Claims (2)
1. heavy caliber antistatic epoxy GRP pipe; Mainly form by pipeline outer wall, inner-walls of duct, glass fibre high strength yarns winding layer; It is characterized in that the carbon fiber felt conductive layer being set near inner-walls of duct; Carbon fiber felt conductive layer skin is a glass fibre high strength yarns winding layer; Glass fibre high strength yarns winding layer is intersected Wrapping formed through epoxy resin infiltration rear screw by glass fibre high strength yarns and graphite fiber yarn, pipeline outer wall, inner-walls of duct all have epoxy resin layer to cover, and obtain antistatic high-strength epoxy GRP pipe through curing in the high temperature.
2. heavy caliber antistatic epoxy GRP pipe according to claim 1 is characterized in that the graphite fiber yarn structural distribution that in pipeline, assumes diamond in shape.
