Abstract
The invention provides a polyester imide aluminum wire coating enamel modifying agent, comprising the following compositions in weight portion: 10 to 30 portions of a phenolic resin, 10 to 20 portions of an epoxide resin, 1 to 10 portions of a poly-hydroxyl acrylic acid resin, 1 to 5 portions of a fluorocarbon surface active reagent and 30 to 60 portions of cresol m/p mixture. According to the formula, the phenolic resin, the epoxide resin, a cementing compound and the fluorocarbon surface active reagent are mixed and dissolved in a cresol m/p mixture solution and are stirred evenly at a temperature of between 40 and 60 DEG C so that the stable transparent fluid oil matter is produced. The polyester imide aluminum wire coating enamel modifying agent has the advantages that the modifying agent designed by the polyester imide copper wire coating enamel is added in the production, after the treatment of the preparation technique, the adhesive attraction of the polyesterimide wire enamel on the aluminum product is improved evidently, various performance indexes of the aluminum enamelled wire coated by the EIW insulated paint modified by the composite material meet the international electrician IEC standard requirement, and the heat-resisting index can be improved up to 220 grade.
Description
Technical field
The present invention relates to a kind of polyester imine aluminium wire wire coating enamel modifier, and preparation technology, this properties-correcting agent is used to make 220 grades of polyester-imide aluminum steel enamelled wire insulated paints.
Background technology
Since 2005, owing to sharp rising of copper valency, some Production of Enamel Wires producers and motor manufacturer begin to use instead aluminum steel and substitute copper cash for reducing production costs and material cost, produce and use aluminium enamel-covered wire.Though the price of aluminum steel is low, proportion is little, and resistivity is than copper height, and temperature increases during with the motor operation of equipower, so the temperature classification to aluminium enamel-covered wire requires to improve under the same service condition, promptly 200 grades of copper enameled wires will could be substituted by 220 grades of aluminium enamel-covered wires.
In addition because the thermal expansivity of aluminum steel is bigger than copper cash, after former 200 grades of polyesterimide wire enamels that are used to coat copper cash directly are used for coating aluminum steel, because thermal stresses changes, ubiquity sticking power variation, the defective that thermal shock resistance properties descends, more do not reach 220 grades thermal level requirement, what make enamel insulated aluminium wire uses and promotes the restriction that is subjected to a certain degree.
Summary of the invention
Technical problem to be solved by this invention is polyester imine aluminium wire wire coating enamel modifier, in the process of producing polyester imine aluminium wire wire coating enamel, add this properties-correcting agent, can significantly improve the sticking power of polyesterimide wire enamel, improve temperature classification to 220 grade aluminium.Be used for the modification of polyester-imide aluminum steel enamelled wire insulated paint.
Another technical problem to be solved by this invention is to provide the preparation method of above-mentioned polyester imine aluminium wire wire coating enamel modifier.
The present invention solves the problems of the technologies described above the technical scheme of being taked: a kind of polyester imine aluminium wire wire coating enamel modifier wherein, comprises following component in weight part:
