Abstract

The invention relates to a processing process of a polyester glass sintering copper flat wire, in particular to a processing process of a paint-free copper flat wire. The processing process takes the polyester fiber and the glass fiber as the wrapping materials and comprises the following steps: firstly, the polyester fiber and the glass fiber are evenly mixed, wherein the polyester fiber accounts for 40-60 percent and is coiled for later use; secondly, the mixed fiber made in the first step is uniformly wrapped on the copper flat wire; thirdly, the copper flat wire wrapped with the mixed fiber is dried for 5-7 times through a drying oven at the drying temperature of 460 to 500 DEG C; and fourthly, the copper flat wire is cooled and rewound. The formed insulating layer has smooth and uniform in surface, good insulating effect and flexibility; no pollution is generated in the production process, the utilization ratio of material is high, the processing cost is greatly saved, the processing process of the polyester glass sintering copper flat wire is energy-saving and environmental-friendly and conforms to the Chinese industrial policy and the polyester glass sintering copper flat wire is the more ideal winding wire for the present electrical products such as motors, welding machines, reactors, and the like.

Description

The processing technology of polyester glass sintering copper flat wire

Technical field

The present invention relates to a kind of processing technology of not having the lacquer copper strap wire, relate in particular to a kind of processing technology of glass fiber copper-clad lenticular wire.

Background technology

Present glass fiber copper-clad lenticular wire adopts the process processing of impregnating varnish baking substantially.It makes glass fiber have certain tack, easily produces in the production process that solvent at high temperature volatilizees, wrapped head gets rid of problems such as lacquer, craft sanitary is poor, environmental pollution is big.And the material serious waste, the processing cost height, finished surface is of poor quality.

Summary of the invention

The present invention is directed to above problem provides a kind of employing terylene to be " adhesive ", and with terylene and the mixed silk of glass fiber, make the good uniformity of manufactured goods superficial layer, manufactured goods quality height reduces the processing technology of the polyester glass sintering copper flat wire that pollutes simultaneously in the course of processing.

Technical scheme of the present invention is: with dacron thread, glass fiber is wrapped material, according to the following steps processing:

1), doubling; Dacron thread, glass fiber are evenly mixed silk, and wherein dacron thread accounts for 40～60%, and lopping is stand-by;

2), wrapped; The mixed silk thread that last step makes is evenly wrapped on copper strap wire;

3), sintering; Adopt baker, the above copper strap wire that mixes silk thread that is surrounded with is toasted, baking temperature is 460～500 ℃, repeats 5 ~ 7 times;

4), the cooling, take-up makes.

Technology of the present invention does not adopt lacquer, but uses the terylene conduct " adhesive " of about 460～500 ℃ of fusing points instead; When thread, itself and glass fiber are mixed silk, wrapped in the lump then on the copper strap wire core, behind oversintering, the terylene that dissolves will bond together between glass fiber and core and the glass fiber securely.The surface of insulating layer that forms is smooth, even, and insulation effect is good, pliability is good.And pollution-free in the production process, the stock utilization height has been saved processing cost greatly, and promptly energy-conservation environmental protection again meets national industrial policy, is the comparatively desirable winding wires of electric product such as present motor, welding machine, reactor.

Embodiment

The present invention is wrapped material with dacron thread, glass fiber, according to the following steps processing:

1), doubling; Dacron thread, glass fiber are evenly mixed silk, and wherein dacron thread accounts for 40～60%, and lopping is stand-by;

2), wrapped; The mixed silk thread that last step makes is evenly wrapped on copper strap wire;

3), sintering; Adopt baker, the above copper strap wire that mixes silk thread that is surrounded with is toasted, baking temperature is 460～500 ℃, repeats to toast 5～7 times;

4), the cooling, take-up makes.
