Description
Technical field
The present invention relates to the making of electrical equipment wiring harness, particularly relate to the preparation method of high vapor-permeable type electrical equipment wiring harness.
Background technology
Electrical equipment wiring harness is the connecting part connecting each electric equipment in circuit, it is made up of insulating sheath, binding post, wire and insulating wrapping material, along with electronic industry, the development of machinery manufacturing industry, the application of electrical equipment wiring harness is more and more universal, such as microwave oven wire harness, washing machine wire harness etc..Wherein insulating wrapping material typically uses silica gel, the effect of insulation is reached at wire harness Surface coating silica gel, although silica gel is the material of high temperature high voltage resistant, but there is air-locked defect in it, wire can produce heat when energising, these heats are bound in silica gel material, and the time one, wire be caused damage by long meeting, even has an accident.
Summary of the invention
The technical problem to be solved in the present invention is that existing electrical equipment wiring harness is airtight; the wire continued accumulation heat causing inside can produce infringement to wire and even cause the accident, and provides a kind of preparation method while not reducing insulation protection effect with high vapor-permeable type electrical equipment wiring harness for this.
The technical scheme is that the preparation method of high vapor-permeable type electrical equipment wiring harness, comprise the following steps: (1), the Kiselgel A of 20-30 weight portion and the politef mix homogeneously of 3-6 weight portion are put into baking oven heating, heating-up temperature is 60-70 DEG C, and heat time heating time is 10-20min；(2), by the Kiselgel A-politef mixed-powder after heating pour the industrial alcohol stirring of 30-40wt% into, be evaporated to 1/4 volume and form mixed liquor；(3), mixed liquor felt being coated in wire harness surface uniformly, pull wire harness to move with the velocity linear of 2-3m/min during coating, wire harness rotates with the speed of 4-6r/min simultaneously；(4), toasting wire harness surface, baking temperature is 50-60 DEG C, and baking time is 20-30min.
The invention has the beneficial effects as follows to mix silica gel and politef and obtain mixed liquor through process, it is applied directly onto conductive line surfaces, the electrical equipment wiring harness prepared has the advantages that the high temperature high voltage resistant insulation effect of silica gel is good, there is preferable breathability simultaneously, the heat of conductive line surfaces is dispersed into outside linear speed, the working environment of one safety and stability is provided for wire, improves service life and the safety of wire.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described.
Embodiment 1:(1), the Kiselgel A of 20 weight portions and the politef mix homogeneously of 3 weight portions are put into baking oven heating, heating-up temperature is 60 DEG C, and heat time heating time is 10min；(2), by the Kiselgel A-politef mixed-powder after heating pour the industrial alcohol stirring of 30wt% into, be evaporated to 1/4 volume and form mixed liquor；(3), mixed liquor felt being coated in wire harness surface uniformly, pull wire harness to move with the velocity linear of 2m/min during coating, wire harness rotates with the speed of 4r/min simultaneously；(4), toasting wire harness surface, baking temperature is 50 DEG C, and baking time is 20min.
Embodiment 2:(1), the Kiselgel A of 25 weight portions and the politef mix homogeneously of 5 weight portions are put into baking oven heating, heating-up temperature is 65 DEG C, and heat time heating time is 15min；(2), by the Kiselgel A-politef mixed-powder after heating pour the industrial alcohol stirring of 35wt% into, be evaporated to 1/4 volume and form mixed liquor；(3), mixed liquor felt being coated in wire harness surface uniformly, pull wire harness to move with the velocity linear of 2.5m/min during coating, wire harness rotates with the speed of 5r/min simultaneously；(4), toasting wire harness surface, baking temperature is 55 DEG C, and baking time is 25min.
Embodiment 3:(1), the Kiselgel A of 30 weight portions and the politef mix homogeneously of 6 weight portions are put into baking oven heating, heating-up temperature is 70 DEG C, and heat time heating time is 20min；(2), by the Kiselgel A-politef mixed-powder after heating pour the industrial alcohol stirring of 40wt% into, be evaporated to 1/4 volume and form mixed liquor；(3), mixed liquor felt being coated in wire harness surface uniformly, pull wire harness to move with the velocity linear of 3m/min during coating, wire harness rotates with the speed of 6r/min simultaneously；(4), toasting wire harness surface, baking temperature is 60 DEG C, and baking time is 30min.
The present invention uses Kiselgel A as raw material, its aperture is expanded after heating, industrial alcohol is utilized to enter to form composite by politef filling as solvent, have the insulating properties of silica gel and the breathability of politef concurrently, in the coating procedure of step (2), point-to-point speed and the rotating speed of wire harness must strictly control, if beyond restriction scope can cause mixed liquor can not reliable attachment on wire harness surface, lose meaning.
