Problems solved by technology
[0004] At the present stage, styrene-based insulating impregnating varnishes are widely used in the market, but styrene has a low boiling point, is volatile, and has an irritating effect on the skin and respiratory tract. It is not easy to decompose and excrete after entering the human body, and has a certain cumulative effect. The VOC emissions in the process are relatively high, which is harmful to the environment and personnel

Abstract
The invention relates to the field of preparation of enameled wire coating, and specifically discloses a low-volatility polyester imide impregnated resin enamelled wire coating, and a preparation method thereof. The low-volatility polyester imide impregnated resin enamelled wire coating is mainly prepared through mixing and reacting raw materials including xylene, tetrahydrophthalic anhydride, trimellitic anhydride, monoethanolamine, castor oil, trimethylolpropane, neopentyl glycol, zinc acetate, an acrylate diluent, a benzoquinone solution and a curing agent according to a certain mass part ratio. The preparation method is simple, and the prepared low-volatility polyester imide impregnated resin enamelled wire coating has the advantages of stable storage, short gelation time, low volatilization, low toxicity, environmental protection, reduction of the VOC discharge amount, and small harm to human bodies.
Description
technical field [0001] The invention relates to the field of preparation of wire enamel, in particular to a low-volatile polyesterimide impregnated resin wire enamel and a preparation method thereof. Background technique [0002] Environmental protection and energy saving are important themes of current social and economic development. The country has made clear strategic arrangements for these two aspects and implemented an industrial strategic development plan. According to the country's industrial policy, one of the key points of the future development of the insulation material industry should be to adjust the product structure, research and develop environmentally friendly and energy-saving insulation materials; give priority to the development of environmentally friendly and low-carbon insulation materials with a large volume and wide range, such as giving priority to the development of solvent-free Insulating varnishes, water-based insulating varnishes and powder coat...
