preparation example 1

[0065] Add 12.2g of A-174, 22g of deionized water, 13g of isopropanol, 3.5g of OP-10, 3.7g of sodium lauryl sulfate, 0.5g of potassium persulfate into a 250mL reaction vessel, start stirring, and slowly add 13.4g of The mixed solution of perfluorododecyl ethyl methacrylate (that is, the compound with n=11 in the above formula (II)) dissolved in 50mL of toluene was dropped within 1 hour, and the polymerization reaction was carried out at 70-100°C for 4 -6 hours to obtain a viscous liquid, which is the silicone-modified fluorine-containing acrylate copolymer, with a weight average molecular weight of 6500 and a viscosity of 1100 mPa·s, hereinafter referred to as modified resin A12.

preparation example 2

[0067] The preparation conditions and method are the same as in Preparation Example 1, except that 13.4 g of perfluorododecyl is replaced by 13.9 g of perfluorohexadecyl ethyl methacrylate (i.e. the compound of n=15 in the above formula (II)) base ethyl methacrylate to obtain a silicone-modified fluorine-containing acrylate copolymer with a weight average molecular weight of 7300 and a viscosity of 1300 mPa·s, which is called modified resin A16.

preparation example 3

[0069] The preparation conditions and method are the same as in Preparation Example 1, except that 13.4 g of perfluorododecylmethyl is replaced by 12.7 g of perfluoroheptyl ethyl methacrylate (i.e. the compound of n=6 in the above formula (II)) Ethyl acrylate to obtain a silicone-modified fluorine-containing acrylate copolymer, its weight-average molecular weight is 6300, and its viscosity is 1100mPa·s, which is hereinafter referred to as modified resin A7.

Abstract

The invention relates to a peelable anti-condensation material which comprises the following raw materials in parts by weight: 30-65 parts of vinyl silicon oil, 6-15 parts of containing hydrogen silicone oil, 1-5 parts of a vinyl silicon resin, 1-5 parts of a hydrogen-containing silicon resin, 4-10 parts of fluorine-containing silane, 3-8 parts of an organic silicon modified fluorinated acrylate copolymer, 8-20 parts of a reinforcing filler, 10-30 parts of a flame-retardant filler, 1-3 parts of a catalyst and 0.5-2 parts of an inhibitor. The invention further provides a preparation method andapplication of the peelable anti-condensation material. The anti-condensation material for electric equipment is capable of preventing condensation, peelable, good in adherence, good in insulation andflame retardancy and excellent in mechanical property, and is an anti-condensation material with excellent comprehensive properties, the humidity inside the electric equipment can be reduced when theelectric equipment is coated by the material, corrosion can be reduced, and safe and stable operation of the electric equipment can be ensured.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a peelable anti-condensation material for electric equipment, a preparation method and application thereof. Background technique [0002] Power equipment, especially substation terminal boxes, are easily scratched, worn, polluted, and corroded by salt spray, moisture, acid rain, etc. during operation, which not only affects the appearance of the equipment, but also reduces the safety performance , or even malfunction. Especially when the cables pass through the power equipment and the wall, there will be tiny gaps between the equipment and the cables, and it is difficult to seal them. Once water vapor enters and forms condensation, it will cause corrosion, short circuit, jamming, etc. , affect the normal operation of the equipment, and cause safety accidents in severe cases. Therefore, it is necessary to take anti-condensation measures for such equipment. Common a...
