Abstract
The invention discloses a kind of GRP pipes of fire resisting, including glass reinforced plastic pipe channel layer and the refractory insulating layer being arranged in outside glass reinforced plastic pipe channel layer, the glass reinforced plastic pipe channel layer is composed of several fan-shaped glass blooms and several elastic pieces, several sector glass blooms are uniformly distributed along the circumferencial direction of GRP pipe, set an elastic piece between each adjacent two sector glass bloom.When any place of glass reinforced plastic pipe channel layer is by weight, fan-shaped glass bloom is mobile to the center of glass reinforced plastic pipe channel layer, elastic piece is squeezed and deforms, and effectively absorbs from external weight, simultaneously, fan-shaped glass bloom has stronger anti-pressure ability, similar to the pressure-resistant principle of arch bridge, therefore, glass reinforced plastic pipe channel layer of the present invention, it is unlikely to deform, cracks under weight, anti-pressure ability is significantly improved.
Description
Technical field
The present invention relates to field of material technology, and in particular to GRP pipe.
Background technique
Why GRP pipe can be widely applied on ship, be that it is incomparable with other metal pipe materials
Superiority: such as there is excellent corrosion resistance, specific gravity is small, light-weight, simple installation, rapid, easy to maintenance, hydraulics
Can be excellent, flexible design, the adaptation of product are strong, long service life, safe and reliable.
Resin-based materials used in GRP pipe and conduit fittings such as flange are mainly epoxy-resin systems, ring at present
Oxygen resin haves the shortcomings that hardness is big, brittleness is big, is easy to appear crackle when by weight.
Summary of the invention
Technical problem solved by the invention: the anti-pressure ability of GRP pipe is improved.
In order to solve the above technical problems, the invention provides the following technical scheme: a kind of GRP pipe of fire resisting, including glass
Glass steel pipe channel layer and the refractory insulating layer being arranged in outside glass reinforced plastic pipe channel layer, the glass reinforced plastic pipe channel layer is by several fan-shaped glass
Bloom and several elastic pieces are composed, and several sector glass blooms are uniformly distributed along the circumferencial direction of GRP pipe, every phase
An elastic piece is set between adjacent two fan-shaped glass blooms.
Elastic piece and fan-shaped glass bloom are tightly connected.
GRP pipe is primarily subjected to the pressure from outside, such as biggish hydraulic pressure, integrally formed GRP pipe
Layer, outside receiving when larger pressure, is easy to appear crackle.Glass reinforced plastic pipe channel layer is designed to separate structure by the present invention, if by
Dry sector glass bloom and several elastic pieces are composed, when any place of glass reinforced plastic pipe channel layer or many places are by weight, fan-shaped glass
Glass bloom is mobile to the center of glass reinforced plastic pipe channel layer, the elastic piece between each adjacent two sector glass bloom by
It squeezing and deforms, the elastic piece of deformation can be effectively absorbed from external weight, meanwhile, fan-shaped glass bloom has relatively strong
Anti-pressure ability, similar to the pressure-resistant principle of arch bridge, therefore, glass reinforced plastic pipe channel layer of the present invention is not easy under weight
Deformation, cracking, anti-pressure ability are significantly improved.

Following further describes the present invention with reference to the drawings:
Fig. 1 is a kind of structural schematic diagram of the GRP pipe first embodiment of fire resisting；
Fig. 2 is a kind of structural schematic diagram of the GRP pipe second embodiment of fire resisting.

Specific embodiment
First embodiment: Fig. 1 is referred to
A kind of GRP pipe of fire resisting, including glass reinforced plastic pipe channel layer 10, elastomer layer 30, refractory insulating layer 20.
The glass reinforced plastic pipe channel layer 10 is composed of several fan-shaped glass blooms 11 and several elastic pieces 12, several sectors
Glass bloom is uniformly distributed along the circumferencial direction of GRP pipe, sets an elasticity between each adjacent two sector glass bloom
Piece.
Elastomer layer 30 is wrapped in the periphery of glass reinforced plastic pipe channel layer 10, several elastic pieces 12 and 30 one of elastomer layer
Molding, the material of elastic piece are identical to the material of elastomer layer.The material of elastomer layer can be natural rubber, butadiene-styrene rubber,
Butadiene rubber, neoprene, hydrogenated nitrile-butadiene rubber, ethylene propylene diene rubber, silicon rubber, fluorubber.The material of above-mentioned elastomer layer
In, rubber is usually all amorphous state, and amorphous finger substance or material shape are not fixed, and external force can change material shape
Shape, and external force removes material and does not have the characteristic for restoring shape itself.It therefore, is fixed shape by the rubber-moulding of amorphous state
Shape generally first makes rubber prefabricated component, i.e. type embryo, then type embryo is placed in be molded in vulcanizer and is vulcanized.For elastomer layer material
Middle thermoplasticity material, can be by elastomer layer and elastic piece that injection molding is structure as a whole.Above-mentioned, either molding vulcanization is gone back
It is injection molding, elastomer layer and several elastic pieces are integrally formed in type embryo or injection mold.If constituting glass reinforced plastic pipe channel layer 10
Dry sector glass bloom 11 can be embedded in type embryo or injection mold, make elastomer layer and several elastic pieces in type embryo or injection mould
It is combined in tool with several fan-shaped glass reinforced plastic agllutinations, makes the stable structure of glass reinforced plastic pipe channel layer 10.
The refractory insulating layer 20 is wrapped in the periphery of elastomer layer 20.The refractory insulating layer 20 is by GP-486G34 phenol
Urea formaldehyde adds the hexamethylenetetramine C6H12N4 of 8-15% as basis material in reisn base material；It stirs evenly
Afterwards, it then is impregnated with fiber and is wound into molded 10 surface cure of glass reinforced plastic pipe channel layer molding.As a preference, described
The mass fraction that C6H12N4 is added in basis material is 10-12%.About the detailed of fire resistant heat preserving layer component, technique and performance
Thin information can refer to the patent document of application number 201510055845.5, application publication number CN104653885A.
Second embodiment: Fig. 2 is referred to
