Description
Technical field:
The utility model relates to wire rod structure field, relates to a kind of composite paint film of resistance to variable color wire rod that can directly weld in particular.
Background technology:
Traditional wire equipment structure (as accompanying drawing 1) from inside to outside centered by conductor layer 1a, insulating barrier 2a and nylon layer 3a, insulating barrier adopts polyurethane (PU) or nylon layer (PA), the main barrier of discoloration-resistant is insulating barrier, and polyurethane (PU) is formed by vulcabond or polyisocyanates and dihydroxy or polyol addition polymerization.(be generally more than 180 DEG C) in high temperature environments and easily form chromophore-imide structure, this structure causes PU to turn yellow, and oxidation generates diquinone-imide structure further, finally becomes amber, affects the performance of wire rod, its scolding tin poor performance.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, provides a kind of composite paint film of resistance to variable color wire rod that can directly weld, insulating barrier outer cladding one deck refractory layer, substantially solve the problem in the variable color of about 180 DEG C work wire rods, and scolding tin performance is good.
Technology solution of the present utility model is as follows:
A kind of composite paint film of resistance to variable color wire rod that can directly weld, it comprises four-layer structure from inside to outside, be respectively central conductor layer, insulating barrier, refractory layer and nylon layer, described insulating barrier is coated on outside central conductor layer, refractory layer is coated on outside insulating barrier, nylon layer is coated on outside refractory layer, and described refractory layer is the polyamide imide of 3-4um by imide ring and the regular thickness formed that is alternately arranged of amido link.
As preferably, described central conductor layer is formed by many fine copper wire strandings, and the wire diameter of each root fine copper wire is 0.05 ~ 0.1mm.
As preferably, the outer even coated coast of paint coating of each root fine copper wire described.
As preferably, described insulating barrier adopts thickness to be the layer of polyurethane of 3-5um.
As preferably, the thickness of described nylon layer is 2 ~ 3um.
The beneficial effects of the utility model are:
The utility model is coated with one deck polyamide imide at polyurethane outer, polyamidoimide is by imide ring and the regular base polymer be alternately arranged of amido link, vitrification point 250 ~ 300 DEG C, has superior mechanical performance at 250 DEG C, and heat distortion temperature is 269 DEG C.When in high temperature environments, time namely higher than 180 DEG C, wire color turns yellow slightly, variable color is very little, and its scolding tin fusing point is 390 DEG C, dielectric loss temperature 221 DEG C, therefore, after have employed wire rod of the present utility model, the problem in the variable color of about 180 DEG C work wire rods is substantially solved.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment:
