Abstract
The invention discloses a smoke-suppressing flame-retardant cable. The cable prepared by the invention sequentially comprises a conductor, a shielding layer, an insulating layer, a flame-retardant layer and an outer sheath layer from inside to outside, wherein the conductor is a copper conductor, the copper conductor is coated on the conductor shielding layer, the conductor shielding layer is coated on the insulating layer, the insulating layer is coated on the flame-retardant layer, and the flame-retardant layer is coated on the outer sheath layer; the flame-retardant layer is formed by coating acrylic acid paint, so that excellent flame-retardant performance is provided for the cable; the outer sheath layer is prepared from sheath materials, the sheath materials are prepared from PVC resin and nitrile rubber with excellent corrosion resistance as main raw materials, and then the magnesium hydroxide nano material with excellent flame-retardant and smoke-suppressing effects is used as a base material and modified, so that the flame-retardant and smoke-suppressing performances of the matrix are further improved.
Description
Technical Field
The invention relates to the technical field of cables, in particular to a smoke-suppressing flame-retardant cable.
Background
The cable is a main carrier for transmitting electric energy and information or realizing electromagnetic conversion, and is widely applied to various fields such as electric power, rail transit, construction engineering, communication and the like, and is called as a blood vessel and a nerve of national economy. With the rapid development of global economy and the enhancement of human environmental awareness, the requirements of all fields on the quality and performance (such as flame retardant performance, smoke suppression performance, corrosion resistance and the like) of wires and cables are higher and higher, and more fires are caused by the aging of wires and cables, so that the occurrence rate of the fires and the death rate of the fires are reduced, and the low-smoke, flame retardant and environmental protection also become the development direction of the wire and cable industry.
At present, most of the production of environment-friendly low-smoke flame-retardant cable materials is to add a large amount of aluminum hydroxide or magnesium hydroxide into a base material to achieve the flame-retardant effect, however, flame retardance is realized by only relying on a single inorganic material, and the addition amount is large, so that the performance of the cable materials is reduced. In addition, a layer of flame-retardant smoke-suppressing paint can be coated on the outer surface of the inner substrate in the form of a coating in the cable, so that the flame-retardant smoke-suppressing performance of the cable is further improved.
Disclosure of Invention
In order to solve the technical problems, the invention provides a smoke-suppressing flame-retardant cable.
The aim of the invention can be achieved by the following technical scheme:
the smoke-suppressing flame-retardant cable comprises a conductor, a shielding layer, an insulating layer, a flame-retardant layer and an outer sheath layer in sequence from inside to outside, wherein the conductor is a copper conductor, the conductor shielding layer coats the conductor, the insulating layer coats the conductor shielding layer, the flame-retardant layer coats the insulating layer, and the outer sheath layer coats the flame-retardant layer;
the conductor shielding layer is an aluminum-plastic composite tape shielding layer, the insulating layer is polyvinyl chloride, the flame-retardant layer is formed by coating acrylic paint, and the outer sheath layer is prepared from sheath materials.
The acrylic coating is prepared by the following steps:

The invention has the beneficial effects that:
the cable prepared by the invention sequentially comprises a conductor, a shielding layer, an insulating layer, a flame-retardant layer and an outer sheath layer from inside to outside, wherein the conductor is a copper conductor, the conductor shielding layer is coated with the conductor, the insulating layer is coated with the conductor shielding layer, the flame-retardant layer is coated with the insulating layer, and the outer sheath layer is coated with the flame-retardant layer; the flame-retardant layer is formed by coating acrylic acid paint, so that excellent flame-retardant performance and corrosion resistance of the cable are provided; the outer sheath layer is prepared from sheath materials, the sheath materials are prepared from PVC resin and nitrile rubber with excellent corrosion resistance as main raw materials, and then the magnesium hydroxide nano material with excellent flame-retardant and smoke-suppressing effects is used as a base material and modified, so that the flame-retardant and smoke-suppressing performances of the matrix are further improved.
In the acrylic acid coating, firstly, cyanuric chloride is used as an intermediate, and a product 1 containing a terminal hydroxyl group is synthesized by utilizing the reaction between an amino group on ethanolamine and chlorine atoms in cyanuric chloride; secondly, carrying out substitution reaction between residual chlorine atoms in the product 1 and hydroxyl groups of the diethyl methylphosphonate acrylate, so as to introduce a phosphate structure into the product 2; then, an acyl chloride reaction is carried out by utilizing a hydroxyl end group in the product 2 and an acyl chloride group in the acrylic chloride to synthesize a double bond end flame-retardant product; then, methyl methacrylate, ethyl acrylate and a terminal double bond flame-retardant product are used as the synthetic raw materials of the flame-retardant acrylic resin; finally, acrylic resin and flame-retardant acrylic resin are used as raw materials to prepare the acrylic paint. In the combustion process, a large amount of phosphorus elements exist on the surface of a carbon layer generated on the surface of a matrix, and the phosphorus elements are generated by the decomposition of a phosphate structure when heated, so that the polymer is promoted to form a large amount of carbon through cyclization and crosslinking, and the formed compact carbon layer can effectively inhibit the generation of salt mist and prevent the further combustion of the matrix; the triazine ring serves as a carbon source when the matrix is combusted, forms a framework of the carbon layer, plays roles in isolating heat and preventing the diffusion of flammable gas, and can dilute the flammable gas and oxygen in the air when nitrogen element is generated during combustion, so that the matrix is inhibited from being combusted. In addition, the acrylic paint also has better corrosion resistance and can be well adhered to the polyvinyl chloride material of the insulating layer.
PVC resin and nitrile rubber are used as base materials in the sheath material, and an auxiliary agent is added to improve the flame-retardant smoke-suppressing performance and corrosion-resistant performance of the sheath material. The addition of MgOH NSs/COF nano-materials improves the flame-retardant and smoke-suppressing performance of the matrix, which is caused by the synergistic action of magnesium hydroxide and COF. In the nano material, firstly, amino groups are modified on the surface of a nano sheet by using a silane coupling agent; then, the amino groups on the surfaces of the nano sheets react with-Cl groups in the COF to form-NH-chemical bonds for connection, so that the amino groups and the-Cl groups are tightly combined, a mesoporous structure is formed at the joint of the amino groups and the-Cl groups, and smoke generated during the combustion of a matrix can be effectively adsorbed, so that the smoke suppression effect is achieved; the magnesium hydroxide nano-sheets are easy to decompose when the substrate burns to generate MgO films, and the MgO films are uniformly and completely covered on the surface of the substrate to play a role in protecting and isolating, and the holes left in the material after the nano-magnesium hydroxide is decomposed are smaller, so that the heat insulation effect of carbon residue is improved, the thermal decomposition of the substrate is slowed down, and the generation and overflow of smoke are reduced.
