Abstract
The utility model provides a low smoke and zero halogen inflaming retarding environment-friendly insulation flexible cord which is a low smoke and zero halogen inflaming retarding environment-friendly cross bonding polyolefine insulating layer wrapped by a conductor and formed by intertwisting a plurality of strands of tinned wires. The manufacture craft is as follows: a plurality of strands of tinned wires are intertwisted into a conductor, and the low smoke and zero halogen inflaming retarding environment-friendly cross bonding polyolefine insulating layer is extruded and is irradiated and cross bonded by an electronic accelerator. The conductive wire with a light structure has a structure of an insulating layer with a thin wall, smaller external diameter, lighter weight and up-to-standard electric and mechanical performance. The utility model has the advantages that the mechanical performance of the product is good, the insulating layer is irradiated and cross bonded so that the prior linear structure is converted into a three-dimensional structure, and the mechanical strength of the insulating layer is improved; the flexibility is good, and the product has the property of zero halogen; the material has low smoke and zero halogen, the electric wire has a small amount of smoke formation in the flame burning process, the release amount of acidic gas is small, and the fire resistance performance is good; the electric wire insulating layer is made of a special material so that the electric wire satisfies the requirement of kind A of vertically burning into a bunch; and the content of hazardous substance satisfies the requirement on the content of hazardous substance prescribed under European Union ROHS Instruction.
Description
Technical field
The utility model relates to a kind of environment-friendly type insulated cord of low-smoke non-halogen flame-retardant and manufacture craft that mainly is connected usefulness with electric power, electronic equipment internal, belong to technical field of electric wires and cables at the permanent wiring that heat-resisting requirement is arranged.
Background technology
For many years, the cable and wire that uses on the domestic and international market, its insulating material mainly are polyvinyl chloride and polythene material.Easy breaking out of fire during electric wire short circuit that the traditional polyvinyl chloride of this employing, polyethylene process are produced, smoke density is big during burning, and can produce a large amount of harmful halogen gass, the physical and mental health and the property safeties that directly endanger the user.Meanwhile, European Union member countries finish electric and electronic equipment is scrapped facture on November 8th, 2002, and on January 27th, 2003 formally announced " waste electronic andelectrical equipment instruction " (WEEE-2002/96/EC) and " about in electronic electric equipment, banning use of the instruction of some harmful substances " (RoHS-2002/95/EC), its main purpose is to reduce the discarded object of electric and electronic equipment and set up to reclaim and utilize system again, thus reduce these materials when discarding, burying and burning to human body and environment the impact and the harm that may cause.From on July 1st, 2006, the electronic and electrical equipment of defined can not contain the harmful substance of being mentioned in the RoHS instruction (lead, mercury, cadmium, Cr VI, Polybrominated biphenyl and Poly Brominated Diphenyl Ethers) in all WEEE instructions when entering the European market." RoHS instruction " and " WEEE instruction " these two instructions propose higher environmental requirement to the telecommunications product, and products export is had an immense impact on, and relate to the relevant whole industry chain of product.Enterprise's exploitation Green Product is responded actively european union directive, breaks through the green trade fort, and improving international competitiveness is the new problem that enterprise faces.
Summary of the invention
The utility model proposes the environment-friendly type insulated cord of a kind of low-smoke non-halogen flame-retardant, be intended to solve the problems referred to above that exist in the existing hookup wire, that this product has is not halogen-containing, do not produce pernicious gas and corrosive gas, the amount of being fuming is seldom during burning, have good flame retardancy, harmful substance contents meets characteristics such as ROHS instruction.
The technical solution of the utility model: it is characterized in that by stranded conductor outsourcing low-smoke non-halogen flame-retardant environment-friendly type cross-linked polyolefin insulating barrier that forms of multiply tinned wird or outsourcing thin-walled low-smoke non-halogen flame-retardant environmental protection cross-linked polyolefin insulating barrier.The manufacture craft of low-smoke non-halogen flame-retardant environmental protection insulation cord is to adopt multiply tinned wird stranded conductor, extrudes low-smoke non-halogen flame-retardant environmental protection cross-linked polyolefin insulation and crosslinked by electron accelerator irradiation.The insulate manufacture craft of light-duty cord of another structure low-smoke non-halogen flame-retardant environmental protection is to adopt multiply tinned wird stranded conductor, and extruding thin-walled low-smoke non-halogen flame-retardant environmental protection cross-linked polyolefin insulation is also crosslinked by electron accelerator irradiation.
Advantage of the present utility model: product good mechanical property: cross-linking radiation is carried out in insulation, make original linear structure be transformed into stereochemical structure, thereby improved the mechanical strength of insulating barrier; Good flexibility: product Halogen characteristic: material adopts the low smoke and zero halogen material, and electric wire amount of being fuming when flame combustion is little, and sour gas discharges few; Fire resistance is good: wire insulation adopts special material, makes electric wire can reach the vertical bunchy combustion requirements of category-A; Harmful substance contents meets the harmful substance contents requirement of regulation in the ROHS of the European Union instruction.The thinwalled insulation layer has littler external diameter, lighter weight, electric and mechanical performance conformance with standard requirement.
Description of drawings
The structural representation of accompanying drawing 1 outsourcing low-smoke non-halogen flame-retardant environmental protection cross-linked polyolefin insulating barrier.
Accompanying drawing 2 is structural representations of outsourcing thin-walled low-smoke non-halogen flame-retardant environmental protection cross-linked polyolefin insulating barrier.
Among the figure 1 adopts the stranded conductor, the 2nd that forms of multiply tinned wird, low-smoke non-halogen flame-retardant environmental protection cross-linked polyolefin insulating barrier, the 3rd, thin-walled low-smoke non-halogen flame-retardant environmental protection cross-linked polyolefin insulating barrier.
Embodiment
Another thin-wall construction is to adopt the stranded conductor that the forms 1 outsourcing thin-walled low-smoke non-halogen flame-retardant environmental protection cross-linked polyolefin insulating barrier 3 of multiply tinned wird.
The manufacture craft of low-smoke non-halogen flame-retardant environmental protection insulation cord: adopt multiply tinned wird stranded conductor, extrude low-smoke non-halogen flame-retardant environmental protection cross-linked polyolefin insulation and crosslinked by electron accelerator irradiation.
Described stranded conductor: adopt stranded the forming of multiply tinned wird;
Described insulating exruded: it is insulating exruded to adopt extraordinary cross-linked polyolefin material to carry out outside stranded conductor, by the high energy electron acceleration equipment sheath is carried out cross-linking radiation.
The thinwalled insulation layer has littler external diameter, lighter weight, electric and mechanical performance conformance with standard requirement.
Should have following requirement:
1) Liao mechanical and physical performance and processing performance should be not less than the like product material therefor;
2) parameters such as material content of halogen, smoke density, oxygen index should be better than the product standard setting;
3) testing agency of Liao environmental protection characteristic through qualification is arranged detects and confirms;
