Abstract
The utility model relates to reinforced thermoplastics pipes, including nano material modified high-density polyethylene inner layer, the external wall of which is provided with a composite polyesterfibre layer, and the external wall of the composite polyester fibre layer is provided with a nano material modified high-density polyethylene outer layer. The beneficial effects of the utility model are that compression resistance, modulus and impact resistance of the inner layer pipes are improved compared with the pure high-density polyethylene pipes, and the service lifetime of the pipes is prolonged; the composite polyester fiber layer is composed of composite polyester material generated by polycondensation of nano material and polyester raw material, thus the molecular performance of thecomposite polyester is improved. The external layer is a nano material modified high-density polyethylene layer, wherein the modified action of the nano material improves the strength of the externallayer, the cost performance is easier to be accepted by marketplace, at the same time, the utility model also reserves the flexibility of pure polyethylene pipes and is capable of being made into long coiling pipes for transmission and usage.
Description
Technical field
The utility model relates to a kind of reinforced thermoplastics tubing.
Background technique
Reinforced plastic tubing has two big classes, and the first kind is a reinforced thermosetting plastics tubing, promptly common alleged frp pipe; Second class is a reinforced thermoplastics tubing, and the disadvantage of frp pipe is to coil, and therefore, lays and transport all very inconvenient.At present, reinforced thermoplastics tubing mainly is to use Steel Skeleton, hole pattern slab skeleton or steel wire twine, to thermoplastic plastic pipe (for example, polyethylene or polypropylene plastics tubing) strengthen, but, the plastic tube of Zeng Qianging like this, owing to have bigger and uneven internal stress between steel and the plastics, strengthen DeGrain, but also have the connection of tube and tube, butt joint, problems such as end-blocking, simultaneously, because traditional hdpe pipe inner wall surface is crude, very easily cause to be transferred material fouling and constantly thickening, and then stop up, become the main cause that finally causes pipe to be scrapped.Pipe regeneration after scrapping is poor, also can impact environment.A kind of reinforced thermoplastics tubing is arranged at present, and it is with the reinforcing material of fiber as thermoplastic plastic pipe.These fibers are synthetic fiber, glass fibre, carbon fiber or aramid fibre, and wherein, what the enhancing effect was best is aramid fibre.But the price of this fiber is tens of times of plastics, therefore, is difficult to promote in developing country.
The model utility content
The purpose of this utility model provides a kind of reinforced thermoplastics tubing, and existing to make the reinforced thermoplastics tubing price of reinforcing material by aramid fiber or carbon fiber expensive to overcome, poor performance, the deficiency that working life is short.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of reinforced thermoplastics tubing, comprise nano-material modified high density polyethylene (HDPE) internal layer, the outer wall of described internal layer is provided with the composite polyester fiber layer, the outer wall of composite polyester fiber layer is provided with nano-material modified high density polyethylene (HDPE) skin, described internal layer, composite polyester fiber layer and outer compound being structure as a whole.
The beneficial effects of the utility model are: because the existence of nanometer material, not only make crushing resistance, modulus and the impact resistance of internal layer tubing improve 30%, 30% and 80% respectively than pure hdpe pipe, and the internal layer tube surfaces is more smooth, transporting resistance reduces, the material that is transferred is difficult at tube wall incrustation, and prolong the working life of tubing; Constituting the complex polyester of composite polyester fiber layer, is the composite polyester material that generates with the polyester raw material polycondensation with nanometer material.Because nanometer material has participated in polycondensation reaction, and the performance of gained complex polyester molecule is improved.Compare with pure polyester molecule, the degree of crystallinity of complex polyester molecule and the degree of orientation improve, and intermolecular active force strengthens, and have fundamentally overcome the shortcoming of pure polyester material.Therefore, the fiber that makes with this complex polyester, compare with pure polyester fibre, its intensity improves 30%, and percent thermal shrinkage＜5%, skin are nano-material modified high-density polyethylene layer, wherein the modifying function of nanometer material has improved outer field intensity, and because outer the extruding with the composite polyester fiber layer combines, this extrusion modling typing has further improved composite polyester fiber layer strength and stiffness again.Therefore, the working pressure of tubing can reach 6～14Mpa, bursting pressure can reach 40Mpa, with being on close level of the thermoplastic plastic pipe of strengthening with expensive aramid fibre, its price performance is easier to be accepted by market, the flexibility that has also kept pure polyvinyl piping materials simultaneously can be made into long coil pipe transportation and use.
