Embodiment 1
[0037] According to the formula of solvent-impregnated resin for high and low frequency electronic transformers of the present embodiment:
[0038] 45g of polyester resin, 20g of 582-2 amino resin, 6g of oily phenolic resin, 0.1g of cobalt naphthenate, 9g of 200# solvent oil, and 20g of xylene.
[0039] After the above-mentioned components are uniformly mixed according to the formula, the solvent-impregnated resin for high- and low-frequency electronic transformers is obtained. When the impregnating resin is in use, it should be cured at about 120°C for 2 hours to form a film.
Embodiment 2
[0041] According to the formula of solvent-impregnated resin for high and low frequency electronic transformers of the present embodiment:
[0042] 55g of polyester resin, 15g of 582-2 amino resin, 10g of oily phenolic resin, 1.0g of ammonium p-toluenesulfonate, 4g of 120# solvent oil, and 15g of xylene.
[0043] After the above-mentioned components are uniformly mixed according to the formula, the solvent-impregnated resin for high- and low-frequency electronic transformers is obtained. When the impregnating resin is in use, it should be cured at about 120°C for 2 hours to form a film.
Embodiment 3
[0045] According to the formula of solvent-impregnated resin for high and low frequency electronic transformers of the present embodiment:
[0046] 60g of polyester resin, 10g of 582-2 amino resin, 7g of oily phenolic resin, 0.5g of zinc isooctanoate, 13g of xylene, 10g of 1500# solvent oil.
[0047] After the above-mentioned components are uniformly mixed according to the formula, the solvent-impregnated resin for high- and low-frequency electronic transformers is obtained. When the impregnating resin is in use, it should be cured at about 120°C for 2 hours to form a film.

Abstract
The invention discloses impregnating resin for high-frequency and low-frequency electronic transformers. The impregnating resin comprises the following materials in percent by weight: 45-60% of polyester resin, 10-20% of a curing agent, 5-10% of oily phenolic resin, 0.02-2% of a functional additive and 25-40% of a diluting agent. Compared with the prior art, the impregnating resin has the advantages that (1) the manufacturing process is simple and the stability of composition is good; (2) not only are the mechanical strength and the bonding force improved, but also the softness is improved, the aspects of heat resistance and strong permeability are also excellent, the heat-resistant level can reach F level, and the comprehensive performance is better; (3) the impregnating resin also has the advantages of fast low-temperature curing, strong permeability, good internal drying performance, excellent secondary solderability and stable storage and the like. The impregnating resin disclosed by the invention does not contain dangerous and forbidden matters specified by the European ROSH regulations, completely meets the requirement on the impregnation process of the electronic transformer, and is excellent electronic-insulating impregnating varnish which can be comparable with foreign similar products.
Description
technical field [0001] The invention relates to an impregnating resin, in particular to an impregnating resin for high and low frequency electronic transformers. Background technique [0002] Electronic transformers are indispensable components of electronics, communications and household appliances. In today's information age, with the rapid development of the information industry, electronic transformers have developed more rapidly. In the "Pearl River Delta" region of South my country, foreign-funded, wholly-owned or joint-venture electronics manufacturers, mainly electronic transformers, have sprung up like mushrooms. In recent years, there have been more and more electronics manufacturers in the "Yangtze River Delta" region. Electronic transformers are composed of various materials and components, and their quality, technological progress and development are inseparable from the reliability of material components and technological progress and development. Insulation ...
