Abstract

The invention discloses a wet bonding resistant alcohol soluble self-bonded paint and a preparation method thereof. According to the preparation method, p-cresol, dimethylbenzene and butanol are taken as a mixed solvent, ES-08, IC alcohol-soluble nylon and epoxy resin are taken as the main raw materials, and a lubricant is taken as an addition agent. The alcohol-soluble nylon is added into equipment and is dissolved by the mixed solvent into an intermediate semi-finished product, and the epoxy resin and a certain proportion of lubricant are added for modification and reaction so as to obtain the product. As the epoxy resin with high molecular weight, high softening point and good humidity resistance is taken as the cooperative modified resin of the alcohol-soluble nylon, and a proper proportion of a lubricant and the mixed solvent with gradually steady evaporation property are added for cooperation, so that the wet bonding resistance of the enameled wire self-bonded paint is greatly improved; the prepared product has good homogeneity and storage stability; and chemical components of low chemical activity are adopted for cooperation, so that the production requirement of the product in production process is lowered, and the property of the product is more stable.

Description

technical field

[0001] The invention relates to an enameled wire self-adhesive varnish and a preparation method thereof, in particular to an alcohol-soluble self-adhesive varnish with anti-moisture sticking and a preparation method thereof. Background technique

[0002] Alcohol-soluble self-adhesive varnish is the self-adhesive varnish with the largest demand in self-adhesive enameled wire enamel. It is widely used in electroacoustic coils because of its low-level alcohol (ethanol, methanol) dissolution and adhesion properties, which improves the processing efficiency of the coil. , magnetic card coils, inductance coils, special micro-motor coils and other special electronic wires with (without) skeletons.

[0003] Alcohol-soluble nylon (PA) is usually used as the main film-forming material of this type of self-adhesive paint, and phenolic resin is used as a modified resin synthesis product. In practical applications, due to the hygroscopicity and low crystallinity (lower h...
