Abstract
The invention provides polyurethane enamelled wire paint. The paint is characterized by being prepared from the following components in parts by weight: 10-20 parts of polyester polyol, 10-32 parts of dimethyl terephthalate, 30-82 parts of ethylene glycol, 20-30 parts of glycerinum, 1-2 parts of auxiliaries and 50-100 parts of deionized water. According to the paint, polyester polyol is used as a base material, and heterocyclic triatomic alcohol is constructed in the polymerizing process, so that the thermal performance of the polyurethane enamelled wire can be improved; furthermore, bromine, acetic acid and other auxiliaries are added to serve as the auxiliary part instead of organic matters, so that the high temperature resistance of the polyurethane enamelled wire can be further improved. The polyurethane enamelled wire paint has the advantages of no saline pin-hole, acid resistance, alkali resistance and aging resistance.
Description
Technical field
The present invention relates to paint vehicle field, particularly a kind of Polyurethane Coating for Wire.
Background technology
Polyurethane paint is important enamelled wire insulated paint, have excellent electrical insulating property and directly weldering property (the most do not remove paint film
Just can the performance of direct scolding tin), at the colour TV that solder joint is more, instrument, the industry such as computer is widely used.
Poly-ammonia is made enamel-covered wire and is proposed requirements at the higher level by the development of science and technology, as inclined in the colour TV in colour TV production domesticization engineering
Switch coil polyurethane enamelled wire, it is desirable to resistance to more than 3000 volts high pressure, cut through temperature more than 245 DEG C, salt-free water pin hole, resistance to
Sour, alkaline-resisting, ageing-resistant, the feature of the excellent straight weldering of polyurethane enamelled wire must be kept again simultaneously.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of Polyurethane Coating for Wire, and this paint vehicle has high pressure resistant, high
The features such as cut through temperature, product both salt-free water pin holes, acidproof, alkaline-resisting, ageing-resistant, keep the most again polyurethane enamelled wire excellent
The feature of good straight weldering.
The technical scheme that the present invention solves technical problem is as follows:
A kind of Polyurethane Coating for Wire, it is characterised in that formulated according to following weight ratio by formula as below:
PEPA 10-20 part
Dimethyl terephthalate (DMT) 10-32 part
Ethylene glycol 30-82 part
Glycerol 20-30 part
Adjuvant 1-2 part
Deionized water 50-100 part.
As one of preferred scheme, it is characterised in that described adjuvant includes bromine, acetic acid, sodium thiosulfate and potassium iodide.
The invention has the beneficial effects as follows: this invention, with PEPA as bed material, is built into a heterocycle in polymerization process
Trihydroxylic alcohol, to improve the hot property of polyurethane enamelled wire.It addition, by adding the adjuvant such as bromine, acetic acid, to replace organic work
For adjuvant part, improve the heat-resisting ability of polyurethane enamelled wire further, possess salt-free water pin hole, acidproof, alkaline-resisting, ageing-resistant
Advantage.
Detailed description of the invention
Below with reference to embodiment, the technique effect of design, concrete structure and the generation of the present invention is carried out clear, complete
Ground describes, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is the one of the present invention
Section Example rather than all embodiment, based on embodiments of the invention, those skilled in the art is not paying creativeness
Other embodiments obtained on the premise of work, belong to the scope of protection of the invention.
Embodiment 1: a kind of Polyurethane Coating for Wire, it is characterised in that prepared according to following weight ratio by formula as below
Form:
PEPA 15 parts
Dimethyl terephthalate (DMT) 21 parts
Ethylene glycol 52 parts
Glycerol 25 parts
Adjuvant 1 part
Deionized water 75 parts.
Above the better embodiment of the present invention is illustrated, but the invention is not limited to described enforcement
Example, those of ordinary skill in the art also can make all equivalent modifications on the premise of spirit of the present invention or replace
Changing, modification or the replacement of these equivalents are all contained in the application claim limited range.
