Description
【Technical field】
The present invention relates to pipe technology field, more particularly, to a kind of glass reinforced plastic pipe.
【Background technology】
The tubing used on domestic market generally steel pipe, pvc pipe, pipe of cement and general glass reinforced plastic pipe.Steel pipe is one
Kind of traditional piping material, by steel plate spiral winding into being welded after cylindrical shape, heavier-weight installs inconvenience and resistance to corrosion is poor；
Steel pipe when underground operation is imbedded, bury with the presence or absence of factors such as electric fields near area by water quality, surrounding soil, underground water in pipe,
Pipe inside and outside wall can be set to produce corrosion.Therefore, standard regulation：Body surfaces externally and internally should coat asphalitine or other anti-corrosion materials.
Because coating material is different from the material of steel pipe, in longtime running, by the effect such as cold and hot, hydraulic blow of weather, easily produce
Raw interface debonding comes off, and progressively loses anti-corrosion coat, so that the inner surface iron molecule of pipe produces oxidation, electrochemistry
Corrosion etc., will reduce service life.The operating condition that steel pipe is required in welding is higher, receives condition in work progress at the scene
Limitation welding quality be often difficult to ensure that, therefore weld sealing reliability not as good as glass reinforced plastic pipe, booster phenomenon is exactly
In the weld of steel pipe.The intensity of other pvc pipe is too low, it is actually used in generally require around to irrigate cement to strengthen resistance to compression
Power, long construction period, and material have certain pollution in itself；Pipe of cement is too heavy, and installation and transportation are inconvenient；These are passed
The roughness coefficien of material under the overall leadership is high, and absolute roughness is big, and wall surface resistance is big.Fiberglass is a kind of infant industry material to mould Dai Gang
Material, the fiberglass that past people see is the fiberglass reinforced plastics being composited by glass fibre and resin binder；Make
Binding agent is epoxy resin or unsaturated polyester resin；The main making material of existing GRP pipe is unsaturated polyester (UP)
Resin, it is widely used in the clear advantage such as light weight, specific strength high, corrosion-resistant, frictional resistance is small, long service life
The items such as the essential industry such as chemical industry, power plant, municipal works, sewage disposal field, draining especially in colliery, slip casting and gas pumping
Industrial occasions are even more and are widely used；The glass reinforced plastic pipe of prior art, there is also that anti-pressure ability is poor, and resistance to corrosion is poor, makes
With drawbacks such as short lifes.
【The content of the invention】
In view of the foregoing, it is necessary to provide a kind of anti-aging, anticorrosion, anti-pressure ability by force, the glass of long service life
Steel pipe.
The purpose of the present invention is achieved through the following technical solutions：
A kind of glass reinforced plastic pipe, including internal layer, burning into sand layer and outer layer, the burning into sand layer are located between internal layer and outer layer；Institute
State internal layer be by polyester film, fiberglass surfacing mat, glass fibre knitting felt, bisphenol A type epoxy resin, polyamide curing agent,
Silane coupler, ethyl phthalate, polyurethane and mica are made.
Further, the burning into sand layer is mixed to prepare by silica, quartz sand, flyash and calcium carbonate
Further, the outer layer is made up of surface of polyester felt and furane resins.
Further, meter takes following raw material composition by weight：Bisphenol A type epoxy resin 20-30 parts, polyamide cure
Agent 8-15 parts, silane coupler 1-3 parts, ethyl phthalate 5-7 parts, polyurethane 1-2 parts and mica 8-12 parts, above-mentioned raw materials are mixed
Polyester film, fiberglass surfacing mat and glass fibre knitting carpet veneer are uniformly pressed into internal layer as lamination material.
Further, the burning into sand layer is counted by following raw material by weight：Silica 1 0-12 parts, quartz sand 25-30
Part, flyash 3-6 parts and calcium carbonate 6-10 parts of adhesion are formed, by unsaturated polyester resin as adhesion agent.
Further, the outer layer is by surface of polyester felt and furane resins by weight 1:9 compositions.
Further, the particle grades of the quartz sand are according to the following ratio：
The quartz sand particle of granulometric range 20-30 mesh, quality accounting is 50%；
The quartz sand particle of granulometric range 40-50 mesh, quality accounting is 20%；
The quartz sand particle of granulometric range 60-70 mesh, quality accounting is 15%；
The quartz sand particle of granulometric range 100-150 mesh, quality accounting is 15%.
Glass reinforced plastic pipe of the present invention has the following advantages compared with prior art：Using above-mentioned technical glass steel pipe internal layer using double
Phenol A type epoxy resin has excellent mechanical performance, adhesive property, toughness and good resistance to corrosion, polyamide curing agent
Compared to other curing agent can more effective reinforced epoxy shear strength and toughness.Simple epoxy resin cured product compared with
Crisp, impact resistance and bending-resistant type are poor, add ethyl phthalate to reduce its solidfied material fragility, improve its toughness；Add silane idol
Connection agent can, acid resistance material ageing-resistant, water-fast with reinforcing glass steel pipe, strengthen its toughness and service life.Add polyurethane and
Mica with reinforcing glass steel pipe stability, can improve wearability, heat resistance, resistance to ag(e)ing, chemicals-resistant of resin cured matter etc.
The performance of aspect.Polyurethane can also reduce the water imbibition of resin cured matter, improve compression strength and impact resistance.Burning into sand layer by
Silica, quartz sand, flyash and calcium carbonate are mixed to prepare can be with the rigidity of reinforcing glass steel pipe and anti-pressure ability, quartz sand
Using proportioning of different sizes, glass reinforced plastic pipe is set more preferably to increase anti-pressure ability.After said structure, the intensity of itself increases
Plus, slow down corrosion, extend the service life of glass reinforced plastic pipe.
