Abstract

The utility model discloses provide HDPE to communicate fire-retardant sub- pipe, including HDPE main body tubes, reinforcing fiber layer and furane resins layer, reinforcing fiber layer is set in outside HDPE main body tubes, and furane resins layer is fixedly connected with the outer wall of HDPE main body tubes and is wrapped in outside reinforcing fiber layer.Reinforcing fiber layer and furane resins layer are set outside HDPE main body tubes as a result, can not only promote the flame retardant property of HDPE main body tubes, but also its intensity can be enhanced and its toughness will not significantly reduce.

Description

HDPE communicates fire-retardant sub- pipe

Technical field

The utility model is related to domain of communication equipments, more particularly to a kind of HDPE communicates fire-retardant sub- pipe.

Background technology

Currently, HDPE pipes are widely used in, municipal works, electric wire or cable are connected up, are buried in protection building, are protected It protects in the construction such as post and telecommunications, communication, power pipe be embedded.HDPE is high density polyethylene (HDPE), be it is a kind of have it is good heat-resisting and Cold resistance, chemical stability is good, has higher rigidity and certain toughness, the characteristics such as mechanical strength is good, and dielectric properties are good.But The anti-flammability and mechanical property of tubing are bad, can only be used in general occasion, can not adapt to more harsh environment.

Utility model content

One side according to the present utility model provides HDPE and communicates fire-retardant sub- pipe, including HDPE main body tubes, enhancing fibre Dimension layer and furane resins layer, reinforcing fiber layer are set in outside HDPE main body tubes, and furane resins layer and the outer wall of HDPE main body tubes are solid It connects and is wrapped in outside reinforcing fiber layer calmly.Reinforcing fiber layer and furane resins layer are set outside HDPE main body tubes as a result, both may be used The flame retardant property of HDPE main body tubes is promoted, and its intensity can be enhanced and its toughness will not significantly reduce.

In some embodiments, furane resins layer is Nian Jie with the outer wall of HDPE main body tubes.As a result, can HDPE main body tubes, Reinforcing fiber layer and furane resins layer are fixed to each other.

In some embodiments, it further includes protection jacket layer that HDPE, which communicates fire-retardant sub- pipe, and protection jacket layer is set in furans tree Outside lipid layer.Protection jacket layer can align pipeline in the inner as a result, and structure shields.

In some embodiments, it further includes elastic cord breaker that HDPE, which communicates fire-retardant sub- pipe, and elastic cord breaker is located at protection Between jacket layer and furane resins layer.Elastic cord breaker can enhance the shock resistance of pipe fitting entirety as a result,.

In some embodiments, it further includes flame retardant coating that HDPE, which communicates fire-retardant sub- pipe, and flame retardant coating is coated on protective case Layer is outer.Flame retardant coating can further strengthen the overall flame effect of pipe fitting as a result,.

The utility model has the beneficial effects that：By the way that reinforcing fiber layer and furane resins layer are arranged outside HDPE main body tubes, The intensity and corrosion resistance of HDPE pipes are improved while so that HDPE communication tubes is had preferable high temperature resistance；In its outer setting Elastic cord breaker and protection jacket layer and flame retardant coating, substantially increase the shock resistance of HDPE pipes, make it have fire-retardant, resistance to Erosion, sturdy and durable feature, can use under the harsh environment that other pipe fittings can not use.

Description of the drawings

Fig. 1 is that the HDPE of one embodiment of the utility model communicates the structural schematic diagram of fire-retardant sub- pipe.

Specific implementation mode

The utility model is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 schematically shows that a kind of HDPE of embodiment according to the present utility model communicates fire-retardant sub- pipe.

Referring to Fig.1, it includes HDPE main body tubes 1, reinforcing fiber layer 2 and furane resins layer 3, protection that HDPE, which communicates fire-retardant sub- pipe, Jacket layer 4, elastic cord breaker 5 and flame retardant coating 6.

HDPE main body tubes 1 are located at endonexine, and reinforcing fiber layer 2 is set in outside HDPE main body tubes 1, furane resins layer 3 with The outer wall of HDPE main body tubes 1 is fixedly connected and is wrapped in outside reinforcing fiber layer 2.Glass fibre, carbon fiber can be used in reinforcing fiber layer 2 Dimension etc..Reinforcing fiber layer 2 is greatly improved the intensity of pipe fitting.Furane resins layer 3 has preferable chemical resistance and anti-flammability, And there is good high temperature resistance.

Furane resins layer 3 can be carried out be bonded with the outer wall of HDPE main body tubes 1 by bonding agent, also can directly cure connection.

Protection jacket layer 4 is set in outside furane resins layer 3.Elastic cord breaker 5 be located at protection jacket layer 4 and furane resins layer 3 it Between.Elastic cord breaker 5 can make wavy shaped configuration, can be better against radial impact force and pressure.

Flame retardant coating 6 is coated on outside protection jacket layer 4.The flame retardant property of pipe fitting can be further enhanced.

Above-described is only some embodiments of the utility model.For those of ordinary skill in the art, Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this practicality Novel protection domain.
