Abstract
The invention discloses a flame-resistant polyethylene cable conduit which is characterized in that the polyethylene cable conduit is prepared by the following ingredients in parts by weight: 100 parts of polyethylene base material, 1-2.8 parts of polytetrafluoroethylene, 0.1-1 part of silane crosslinking agent, 0.05-2 parts of a dispersing agent, 2-5 parts of an antioxidant and 10-20 parts of a flame-retardant additive. The flame-resistant polyethylene cable conduit has the beneficial effects that the flame-retardant property of the polyethylene cable conduit is greatly improved and the service life of the polyethylene cable conduit is prolonged.
Description
?
Technical field
The present invention relates to the used wire conduit of cable, specifically, relate to a kind of fire-retardant polyethylene cable conduit.
Background technology
Polyvinyl piping materials is lightweight, maintenance, installation, easy maintenance, be easy to transportation, anti-stress cracking is good, low-temperature impact resistance is excellent, and the performances such as amount of deflection, rigidity, flexibility are good, and the tensile strength of existing Polyethylene insulated cable conduit, shock strength are not high, and flame retardant effect is bad, makes its use be restricted.
Summary of the invention
The object of the present invention is to provide a kind of fire-retardant polyethylene cable conduit.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of fire-retardant polyethylene cable conduit is characterized in that described polyethylene catheter is comprised of the component of following weight part: 100 parts of polyethylene base-materials, tetrafluoroethylene 1-2.8 part, silane crosslinker 0.1-1 part, dispersion agent 0.05-2 part, oxidation inhibitor 2-5 part, flame-retardant additive 10-20 part.
Described oxidation inhibitor is irgasfos 168 or sulfur type antioxidant.
Described sulfur type antioxidant is thiopropionate.
Described flame-retardant additive is the mixture of decabromodiphynly oxide and antimonous oxide, and the weight ratio of decabromodiphynly oxide and antimonous oxide is 1:2-3.
The weight ratio of decabromodiphynly oxide and antimonous oxide is 1:2.5.
Beneficial effect of the present invention: the flame retardant properties of Polyethylene insulated cable conduit of the present invention is greatly enhanced, and has prolonged the work-ing life of Polyethylene insulated cable conduit.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
Get 100 parts of polyethylene base-materials, tetrafluoroethylene 1-2.8 part, silane crosslinker 0.1-1 part, dispersion agent 0.05-2 part, 2-5 part irgasfos 168, flame-retardant additive 10-20 part according to weight part, with each component mixing and stirring, place and namely obtained polythene material in 2 hours, utilize this polythene material to prepare the fire-retardant polyethylene cable conduit.
