Abstract
The utility model provides a composite plastic pipe, comprising a pipe body and is characterized in that the pipe body is divided into an inner wall and an outer wall; a hollow core is arranged between the inner wall and the outer wall which are fixedly connected by at least three uniformly distributed connection ribs; an enhancing layer is arranged at the periphery of the outer wall; as the enhancing layer is arranged at the periphery of the outer wall of the pipe body, the composite pipe is formed, the strength is improved, the composite plastic pipe is suitable for the occasions with higher pressure level and higher annular rigidity, and is good in damage resistance. The pipe body is set to be the hollow core, so the weight is reduced under the condition of meeting the same usage.
Description
Technical field
The present invention relates to a kind of composite plastic pipe.
Background technique
At present, have a kind of plastic tube that adopts expressing technique to make, the tube wall of its body is one deck, and solid, because of characteristics such as internal and external walls are smooth, cost is lower, is widely used.But find after deliberation still to exist following problem: (1), when for open air, often can be subject to the effect of external force, easily breaks; (2) when for elevated pressures grade with compared with high ring rigidity grade occasion or larger caliber, needing has thicker tube wall, but along with the increase of pipe thickness, the strength increase of plastic tube is also few, but has increased weight, and cost significantly increases, less economical.
Fiber reinforced plastic are taking fiber as reinforcing material, composite material taking polymer as matrix, there is specific strength high, specific modulus is large, material property has the features such as designability, corrosion resistance and excellent in durability, in the relevant industries such as Aero-Space, railway, decorative architecture, family's living furniture, building materials bathroom and water power wind-powered electricity generation, is widely applied.
Summary of the invention
The present invention aims to provide that a kind of intensity is high, anti-destructive good, can be applicable to high pressure grade and high ring rigidity grade occasion, lightweight composite plastic pipe.
The technical solution adopted in the present invention is: a kind of composite plastic pipe, comprising body, it is characterized in that: described body is divided into inner and outer wall, is hollow between inner and outer wall, be fixedly connected by least three uniform connection ribs, be provided with enhancement layer in outer wall periphery.
Described outer wall periphery can be provided with at least three axial equally distributed fins or groove.
Described fin or groove can be dove-tail forms.
Described enhancement layer can be to comprise interior enhancement layer, packed layer, outer enhancement layer, and packed layer is located between interior enhancement layer and outer enhancement layer.
Described enhancement layer can be the outer enhancement layer of one deck.
Described packed layer can be silica sand or calcium carbonate.
Described interior enhancement layer, outer enhancement layer can be fiber reinforced plastic.
Described enhancement layer can be to adopt the mode being wound around to be located at the periphery of tube wall.
The invention has the beneficial effects as follows: (1) is arranged with enhancement layer outward at tube wall, becomes composite pipe, has improved intensity, can be applicable to the occasion of high pressure grade, high ring rigidity grade, anti-destructive is good; (2) body is made as hollow, meeting under identical purposes condition, has alleviated weight; (3) be provided with fin or groove in outer wall periphery, reached the more effectively combination of enhancement layer and body, also improved intensity simultaneously; (4) because inside and outside enhancement layer is fiber to be increased to plastics be located at body periphery, under the compound action of fibre reinforced materials, polymeric matrix, intensity is higher, and anti-destructive is better; (5) because inside and outside enhancement layer is to adopt fiber reinforced plastic, can adopt the mode of winding to be located at the periphery of tube wall, production is more prone to, and efficiency is higher.
Brief description of the drawings
Fig. 1 is band rib structures schematic diagram of the present invention.
Fig. 2 is with groove structural representation of the present invention.
Embodiment
The structure of one embodiment of the invention, as shown in Figure 1 and Figure 2, a kind of composite plastic pipe, comprise enhancement layer 1, body 2, body 2 is divided into outer wall 2A and inwall 2D, between outer wall 2A and inwall 2D, is hollow, is fixedly connected by least three uniform connection rib 2B, outer wall 2A periphery can be provided with at least three axial equally distributed fin 2C or groove 2E, and fin 2C or groove 2E can be dove-tail forms.; Be arranged with enhancement layer 1 outward at outer wall 2A, enhancement layer 1 can be to comprise outer enhancement layer 1A, packed layer 1B, interior enhancement layer 1C, packed layer 1B is located between outer enhancement layer 1A and interior enhancement layer 1C, can be according to different requirements, enhancement layer 1 can be the outer enhancement layer 1A of one deck, packed layer 1B can be silica sand or calcium carbonate, and outer enhancement layer 1A, interior enhancement layer 1B adopt fiber reinforced plastic.Because outer, interior enhancement layer 1A, 1C adopt fiber to increase plastics, can adopt the mode of winding to be located at the periphery of body 2 outer wall 2A, production is more prone to, efficiency is higher.
