Abstract
The utility model discloses a structured-wall pipe molded and wound from a fibrous composite material. The pipe structurally comprises a pipe wall and hollow ribs, wherein the pipe wall is wound by a flat belt, the hollow ribs are spirally wound on the outer surface of the pipe wall, and the flat belt comprises two wrapping layers and a fibrous composite material core layer sandwiched between the two wrapping layers. The structured-wall pipe can significantly improve the modulus of elasticity and the ring stiffness of the main body.
Description
Technical field
The utility model relates to a kind of with the Wrapping formed structure-wall pipe material of fibrous composite coextruding heat, belongs to plastic tube processing technique and equipment technical field.
Background technique
At present; large-diameter plastic pipe belongs to chemical building material; be to mould Dai Gang,, to be applied to municipal drainage to mould update product for cement; remote low-pressure water delivery; mine and chemical industry draining, the making of irrigation and water conservancy irrigation and ventilation duct and pressure vessels for the chemical industry etc. are to saving the energy; reduce and pollute, the protection environment is significant.Existing Wrapping formed structure-wall pipe material comprises tube wall and along the hollow rib of outer surface of tube wall helical arrangement, single employing high density polyethylene (HDPE) of its tube wall or polypropylene material are hot-extrudable Wrapping formed, its hollow rib comprises the skeleton pipe layer of polypropylene material or metal material, with high density polyethylene (HDPE) or polypropylene material skeleton pipe layer is carried out multiple coating again and twines.Such structure-wall pipe material, its tubing main body is high-density polyethylene layer or polypropylene layer, and level is single, is subjected to the restriction of elasticity modulus of materials, along with its ring stiffness of increase reduction rapidly of structure-wall pipe material caliber, cause totally unfavorable influence for the normal use of product.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of with the Wrapping formed structure-wall pipe material of fibrous composite, can significantly improve the Young's modulus and the ring stiffness of structure-wall pipe material main body.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of with fibrous composite Wrapping formed structure-wall pipe material, comprise tube wall that flat rubber belting twines in the structure and twine the hollow rib of arranging that described flat rubber belting comprises two clads and is sandwiched in fibrous composite sandwich layer between two clads along the outer surface of tube wall spiral.
Elongation technology scheme of the present utility model is: described hollow rib comprises skeleton pipe layer, fibrous composite pipe layer and cage walls layer from inside to outside.
Described hollow rib comprises fibrous composite pipe layer and cage walls layer from inside to outside.
Described clad is high-density polyethylene layer or polypropylene layer, and described fibrous composite sandwich layer is high density polyethylene (HDPE)-master batch fibrous composite layer.
Described skeleton pipe layer is polypropylene layer or metal layer, and described fibrous composite pipe layer is high density polyethylene (HDPE)-master batch fibrous composite layer, and described cage walls layer is high-density polyethylene layer or polypropylene layer.
Adopt the beneficial effect that technique scheme produced to be: tube wall and hollow rib are based on high density polyethylene (HDPE)-master batch fibrous composite layer, more simple high-density polyethylene layer or polypropylene layer, the Young's modulus of material of main part obtains significantly to promote, thereby has improved the ring stiffness of structure-wall pipe material; Tube wall comprises high density polyethylene (HDPE) clad or polypropylene clad, and hollow rib comprises high density polyethylene (HDPE) cage walls layer or polypropylene cage walls layer, can guarantee that the inner and outer surface of product is smooth smooth, promotes the product appearance quality.
