Abstract
The invention discloses a preparation method for a high permeability electric appliance wire harness, comprising steps of (1) uniformly mixing 20-30 parts by weight of fine-pored silica gel and 3-6 parts by weight of polytetrafluoroethylene, placing the mixture into a baking oven and heating at temperature of 60-70 DEG, wherein the heating duration is 10-20min, (2) pouring the mixing powder of heated fine-pored silica gel and rosin into 30-40wt% industrial alcohol for stirring and performing pressure reduction and condensation on the mixed liquid, the volume of which is reduced to 1/4, (3)uniformly coating the mixing liquid on the surface of the harness through a felt, dragging the harness to perform linear movement at the speed of 2-3/min during the coating process while the harness is rotating at the speed of 4-6r/min, and (4) baking the surface of the harness. The beneficial effect of the preparation method for the high permeability electric appliance wire harness is that the silica gel and the polytetrafluoroethylene are directly applied onto the surface of the lead after processing, and then the electric harness obtained has better permeability.
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, be made up of insulating sleeve, binding post, wire and insulating wrapping material, along with the development of electronic industry, machinery manufacturing industry, the application of electrical equipment wiring harness is more and more general, such as microwave oven wire harness, washing machine wire harness etc.Wherein insulating wrapping material generally adopts 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 being energized, these heats are bound in silica gel material, and the time one, long meeting cause damage to wire, even had 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; cause inner wire continued accumulation heat can produce infringement to wire even to cause the accident, a kind of preparation method while not reducing insulation protection effect with high vapor-permeable type electrical equipment wiring harness is provided for this reason.
Technical scheme of the present invention is: the preparation method of high vapor-permeable type electrical equipment wiring harness, comprising the following steps: (1), the polytetrafluoroethylene of the Kiselgel A of 20-30 weight portion and 3-6 weight portion mixed and puts into baking oven and heat, heating-up temperature is 60-70 DEG C, and heating time is 10-20min; (2) industrial alcohol, by the Kiselgel A-rosin mixed-powder after heating pouring 30-40wt% into stirs, and is evaporated to 1/4 volume and forms mixed liquor; (3), by mixed liquor felt be coated in wire harness surface uniformly, pull wire harness to move with the velocity linear of 2-3m/min in the process of coating, wire harness rotates with the speed of 4-6r/min simultaneously; (4), to wire harness surface toast, baking temperature is 50-60 DEG C, and baking time is 20-30min.
The invention has the beneficial effects as follows and silica gel and polytetrafluoroethylene mixing are obtained mixed liquor through process, directly be coated to conductive line surfaces, obtained electrical equipment wiring harness has the good feature of the high temperature high voltage resistant insulation effect of silica gel, there is good gas permeability simultaneously, the heat of conductive line surfaces is dispersed into outside linear speed, for wire provides the operational environment of a safety and stability, improve useful life and the fail safe of wire.
Embodiment
Below in conjunction with embodiment, the present invention will be further described.
Embodiment 1:(1), the polytetrafluoroethylene of the Kiselgel A of 20 weight portions and 3 weight portions mixed and puts into baking oven and heat, heating-up temperature is 60 DEG C, and heating time is 10min; (2) industrial alcohol, by the Kiselgel A-rosin mixed-powder after heating pouring 30wt% into stirs, and is evaporated to 1/4 volume and forms mixed liquor; (3), by mixed liquor felt be coated in wire harness surface uniformly, pull wire harness to move with the velocity linear of 2m/min in the process of coating, wire harness rotates with the speed of 4r/min simultaneously; (4), to wire harness surface toast, baking temperature is 50 DEG C, and baking time is 20min.
