Abstract
The utility model discloses an inner pipe structure of resin pipes, which is in a double-layer structure and comprises an inner modified layer and an outer thermoplastic elastic body layer. The inner modified layer and the outer thermoplastic elastic body layer are compounded together in co-extrusion mode. The inner pipe structure of the resin pipes is provided with the inner layer structure and the outer layer structure, the inner modified layer can meet requirements for corrosion resistance and high strength which are required in contact with materials inside a pipe, material cost is high, and the outer thermoplastic elastic body layer is low in the material cost. By means of combination of materials of the inner layer and the outer layer, use requirement of users for pipe performance is met, product performance is ensured not to be changed, and whole manufacture cost and use of valuable materials can be reduced.
Description
Technical field
The utility model relates to a kind of composition structure of resin tubing, particularly a kind of resin tubing inner tube structure.
Background technique
The application area of resin tubing is wider, especially automobile, engineering machinery, main equipment etc., thereby the demand of resin tubing increases thereupon.Resin tubing generally is made up of interior pipe, outer tube and the middle level between inner and outer pipe, and wherein interior pipe directly contacts with internal liquid, and its intensity and Corrosion Protection need satisfy certain requirement.In order to satisfy the usage requirement of different occasions, the interior pipe of resin tubing generally need adopt the material of some better performances to process.But because the price of material increases gradually in recent years, the material price of making pipe in the resin tubing also increases thereupon, has therefore hindered the development and the extensive use of resin tubing industry greatly.
Summary of the invention
For addressing the above problem, the utility model provides a kind of with low cost, resin tubing inner tube structure that can satisfy usage requirement.
The utility model is that the technological scheme that its problem of solution is adopted is:
A kind of resin tubing inner tube structure, it is a double layer construction, comprises inter-modification layer and outside thermoplastic elastomer layer, the inter-modification layer with outside thermoplastic elastomer layer coextru-lamination be in the same place.
Preferably said external heat elasto-plasticity bulk layer thickness is greater than the inter-modification layer thickness.
Preferably outside thermoplastic elastomer layer and inter-modification layer are hyaline layer.
The beneficial effect of the utility model is: the utility model is established inside and outside double-layer structure; Wherein the inter-modification layer can satisfy and contacts needed corrosion-resistant, high tenacity requirement with intraductal material; Cost of material is higher, and the cost of material of outside thermoplastic elastomer layer is lower.Utilize combination the utility model of this inside and outside materials at two layers both can satisfy the usage requirement of user, guarantee that product performance are constant, can reduce whole manufacture cost again, save the use of precious materials pipe performance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the utility model structural drawing.
Embodiment
With reference to Fig. 1; A kind of resin tubing inner tube structure disclosed in the utility model; Pipe has used one deck structure that is different from traditional mode of production in it; And being to use double layer construction, double layer construction to comprise outside thermoplastic elastomer layer 1 and inter-modification layer 2, pipe is in the same place by inter-modification layer 2 and outside thermoplastic elastomer layer 1 coextru-lamination in the resin tubing.Outside thermoplastic elastomer layer 1 all is preferably hyaline layer with inter-modification layer 2.
Some preferred embodiment in, inter-modification layer 2 is a nylon layer, 1 on outside thermoplastic elastomer layer is a polyurethane layer.Nylon layer can satisfy and contacts needed corrosion-resistant, high tenacity requirement with intraductal material; Polyurethane layer then has reasonable heat resistance and wear resistance; And its whole cost is lower, so the utility model both can satisfy the usage requirement of user to pipe performance, guarantees that product performance are constant; Can reduce whole manufacture cost again, save the use of precious materials.
In actual product; Thickness proportion between outside thermoplastic elastomer layer 1 and the inter-modification layer 2 can dispose as required; But preferably resin tubing external heat elasto-plasticity body layer 1 thickness is greater than inter-modification layer 2 thickness; The major part that is tubing all is made up of lower-cost outside thermoplastic elastomer layer 1, reaches a more excellent economical with materials cost effectiveness.
For inter-modification layer 2 and outside thermoplastic elastomer layer 1 can well be combined with each other, elite selecting with the co-extrusion production line accomplished production, so pipe is produced through extruding and moulding in the resin tubing.
Claims (3)
1. a resin tubing inner tube structure is characterized in that it is a double layer construction, comprises outside thermoplastic elastomer layer (1) and inter-modification layer (2), and inter-modification layer (2) and outside thermoplastic elastomer layer (1) coextru-lamination are together.
2. a kind of resin tubing inner tube structure according to claim 1 is characterized in that said outside thermoplastic elastomer layer (1) thickness is greater than inter-modification layer (2) thickness.
3. a kind of resin tubing inner tube structure according to claim 1 is characterized in that said outside thermoplastic elastomer layer (1) and inter-modification layer (2) are hyaline layer.
