Abstract
The utility model discloses a fiber-enhanced antistatic plastic pipe for resisting high temperature, which comprises a core pipe 1, an enhanced layer 2, an adhesive layer 3 and an outer layer 4. After being used, cross-linked polyethylene resin is added in an antistatic agent for extruding to form the core pipe 1 on the inner layer; then a fiber bundle is crossed left and right and wound or attached to the core pipe 1 in a knitting way to form the enhanced layer 2; coated resin is extruded from the outer layer of the enhanced layer 2 to form the adhesive layer 3, so that the core pipe 1 and the enhanced layer 2 are adhered together by the adhesive layer; and finally, polyvinyl chloride resin (PVC-M) modified by acrylic acid or cross-linked polyethylene is extruded to coat and form the outer layer 4. The pipe has the characteristics of high strength, high temperature resistance, static resistance, light weight and scratch resistance, has maximum diameter of 630mm and can be widely used for laying of non-digging pipeline and construction of special environments.
Description
Technical field
The utility model relates to a kind of fiber reinforced high-temperature-resistant antistatic plastic pipe
Background technique
Steel wire strengthens tubing and is widely used in engineering construction, and its advantage is light weight, aspect such as flexible.But foot, at present the tubing working pressure of using lacks pressure pipe material in the heavy caliber of the above working pressure 4-6MPa of DN200 all below 1.6MPa, and the also also prematurity of enhancing structural design of pressure pipe material in this heavy caliber.In course of working, the arrangement mode of reinforcing material and become the key factor of restriction tubing stability with the consistency problem of plastic materials, especially in the heavy caliber pipe using process, the link that the uniformity of intensity is fatal especially.In the arduouser Environmental Conditions of some conditions, for example: the field operation environment in mine, oil field, performance requirements such as intensity, toughness, heatproof, light weight and antistatic for tubing are very strict, therefore, press for a series of nonmetal enhancement engineering pipeline tubing of exploitation, on the basis that keeps tradition enhancing tubing advantage, make it have better intensity and lighter quality, to satisfy the composite request of environmental conditions.
Summary of the invention
Use the problem that exists at present enhancing tubing in particular surroundings, the utility model provides a kind of fiber reinforced high-temperature-resistant antistatic plastic pipe.It is characterized in that tubing comprises core pipe 1, enhancement layer 2, adhesion layer 3 and outer 4.Use back cross-linked polyethylene resin (trade mark PEXb2010 Zhangjiagang Lianguan New Material Co., Ltd.) to add antistatic auxiliary agent extruding and moulding internal layer core pipe 1, be attached to intersection winding about nanometer PET (trade mark PET9090 Changzhou Zhaolong Synthetic Materials Co., Ltd.) fiber tuft or with type of weave then and constitute enhancement layer 2 on the core pipe 1, extrude coated with resins (steel wire entwining tube special binding resin Shanghai Banzan Macromolecule Material Co., Ltd) at enhancement layer 2 skins and form adhesion layer 3, make adhesion layer core pipe 1, enhancement layer 2 is bonded together, to extrude the Overmolded skin 4 that is through acrylic acid modified Corvic (PVC-M) (PVC-M produces with high impact modified dose of trade mark IM808A Korea S LG of acrylic acid, Zhangjiagang the successive winning of the number on title new material company) at last.
Tubing of the present utility model adopts antistatic back cross-linked polyethylene resin as internal layer core pipe, and off-line is finished crosslinked, guarantees that normal serviceability temperature can and have antistatic performance up to 110 ℃; Select the fiber tuft of high-strength nano polyester fibre for use as enhancement layer, when increasing substantially intensity, alleviating composite metal plastic pipe weight, reduce the difference of nonmetal enhancement layer and plastic tube thermal expansion coefficient, helped to keep the good and adhesion layer fusion of compound plastic pipe dimensional stability and energy; Select for use resin as adhesion layer, strengthened integrity, homogeneity and the stability of tubing with adhesive property; Adopting PVC-M to extrude clad can effectively prevent the fragility damage of tubing and improve its mar-proof performance.The composite pipe external coating also can use crosslinked polyethylene or other mar-proof good TPO material except adopting ultra-tenacious PVC-M material.
Tubing has the feature of intensity height, high temperature resistant, antistatic, light weight, anti-stroke of damage, and the diameter maximum can reach 630mm, and the construction that can be widely used in non-excavation pipe laying and particular surroundings is used.

Embodiment
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The utility model provides a kind of fiber reinforced high-temperature-resistant antistatic plastic pipe.As shown in Figure 1, tubing comprises core pipe 1, enhancement layer 2, adhesion layer 3 and outer 4.Use the back cross-linked polyethylene resin to add antistatic auxiliary agent extruding and moulding internal layer core pipe 1, be attached to intersection winding about fiber tuft or with type of weave then and constitute enhancement layer 2 on the core pipe 1, extrude coated with resins at enhancement layer 2 skins and form adhesion layer 3, adhesion layer is bonded together core pipe 1, enhancement layer 2, at last PVC-M is extruded the Overmolded skin 4 that is.
In the actual production, add antistatic auxiliary agent by extruding and moulding with extraordinary back cross-linked polyethylene resin, become internal layer core pipe 1, the 1 used back cross-linked polyethylene resin off-line room temperature placement of core pipe is finished crosslinked, can guarantee that every usability of tubing is stable; Afterwards, at core pipe 1 skin, select the high-strength nano polyester fibre for use, about intersect to twine or be attached to and constitute enhancement layer 2 on the core pipe 1 with type of weave, when increasing substantially intensity, alleviating composite metal plastic pipe weight, reduce the difference of nonmetal enhancement layer and plastic tube thermal expansion coefficient and opened, helped to keep the good and adhesion layer fusion of compound plastic pipe dimensional stability and energy; Select the resin with adhesive property for use, extrude and apply formation adhesion layer 3, it is bonded together enhancement layer 2 and core pipe 1; At last, the modified PVC-M that selects good-toughness for use is as outermost surface, extrudes Overmoldedly for outer 4, effectively prevents the tubing brittle failure and improved the mar-proof performance of tubing.Tubing has intensity height, high temperature resistant, antistatic, light weight, anti-stroke and decreases feature, and the diameter maximum can reach 630mm, and the construction that can be widely used in non-excavation pipe laying and particular surroundings is used.
