Description

Halogen-free copper-plastic composite belt with flame retardant property

Technical Field

The utility model relates to a copper is moulded compound area technical field, specifically is a there is not steamed copper of flame retardant property and is moulded compound area.

Background

The copper-plastic composite belt is a substitute of a pure copper belt for cables, and has the excellent performances of light weight, high strength, high temperature resistance, small shrinkage and the like, the surface coating has good waterproof performance, the proportion of plastics in the copper-plastic composite belt is generally larger than that of the general plastics, and the plastics are easy to burn sometimes, so the flame retardant performance is very important for the copper-plastic composite belt, the flame retardant of the plastics generally adopts a flame retardant material containing halogen, the copper-plastic composite belt has environmental pollution, and if the copper-plastic composite belt which does not contain halogen and has good flame retardant performance can be designed, the problems can be solved, and therefore, the halogen-free copper-plastic composite belt with the flame retardant performance is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a there is not steamed copper of fire retardant property and moulds compound area to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a there is not steamed copper of fire retardant property and moulds compound area, includes the plastic layer, the cavity has been seted up to the inside of plastic layer, the inside fixed mounting of cavity has the aluminium hydroxide layer, the upper and lower lateral wall symmetry of plastic layer scribbles first glue film, the lateral wall of first glue film all glues and have steamed fire-retardant polyester film layer, the lateral wall on steamed fire-retardant polyester film layer all scribbles the second glue film, the lateral wall on second glue film all glues and to have the copper foil layer.

Preferably, the outer surface of the copper foil layer is coated with a paint layer.

Preferably, the clamping groove has all been seted up to the lateral wall about the plastic layer, and the both ends are buckled respectively and are inserted to the clamping groove about the copper foil layer.

Preferably, the upper and lower surfaces of the aluminum hydroxide layer are provided with grooves in a staggered manner, and the grooves are filled with nitrogen.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a structure of plastic layer, aluminium hydroxide layer, halogen-free fire-retardant polyester film layer and copper foil layer utilizes halogen-free fire-retardant polyester film layer and aluminium hydroxide layer to play good flame retardant efficiency, and both all do not contain halogen, and better to the environment, nitrogen gas in the aluminium hydroxide layer upper groove simultaneously can flow out when here composite tape burns, plays good flame retardant efficiency, increases the security.

Fig. 1 is a cross-sectional view of the present invention.

In the figure: 1. the plastic layer, 2, the cavity, 3, the aluminium hydroxide layer, 4, first glue film, 5, no halogen flame retardant polyester film layer, 6, the second glue film, 7, the copper foil layer, 8, the lacquer layer, 9, the draw-in groove, 10, the recess.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a there is not steamed copper of fire retardant ability and moulds compound area, including plastic layer 1, cavity 2 has been seted up to the inside of plastic layer 1, the inside fixed mounting of cavity 2 has aluminium hydroxide layer 3, aluminium hydroxide is good flame retardant material, strengthen this compound area's flame retardant efficiency, the upper and lower lateral wall symmetry of plastic layer 1 scribbles first glue film 4, the lateral wall of first glue film 4 all glues to be stained with there is not steamed fire-retardant polyester film layer 5, steamed fire-retardant polyester film layer 5 mainly plays the protection to plastic layer 1, prevent the flame retardant efficiency of its burning, the lateral wall of steamed fire-retardant polyester film layer 5 all scribbles second glue film 6, the lateral wall of second glue film 6 all glues to be stained with copper foil layer.

Specifically, the outer surfaces of the copper foil layers 7 are coated with paint layers 8, and the copper foil layers 7 are protected by the paint layers 8 degrees.

Particularly, the clamping groove 9 is formed in the left side wall and the right side wall of the plastic layer 1, and the left end and the right end of the copper foil layer 7 are respectively bent and inserted into the clamping groove 9, so that the overall firmness of the composite belt is better, and the safety is enhanced.

Specifically, the upper surface and the lower surface of the aluminum hydroxide layer 3 are provided with the grooves 10 in a staggered manner, and the grooves 10 are filled with nitrogen, so that when the composite tape is combusted, the nitrogen in the grooves 10 flows out, the plastic layer 1 can be prevented from being combusted continuously, and a good flame-retardant effect is achieved.

The working principle is as follows: this compound area is moulded to no halogen copper with fire retardant ability mainly utilizes halogen-free fire-retardant polyester film layer 5 to protect plastic layer 1, utilizes aluminium hydroxide layer 3 to carry out supplementary protection to plastic layer 1, avoids the combustion of plastic layer 1, when the combustion takes place for plastic layer 1, can make aluminium hydroxide layer 3 contact the external world, and then can make the nitrogen gas outflow in the recess 10, and it is inert gas, can effectively prevent plastic layer 1 to continue burning.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
