preparation example 1

[0043] The preparation method of zirconia: 1.0L of 10% sodium hydroxide solution is added to the stirring and grinding machine, and then 50g of zirconium oxychloride (Aladdin) is gradually added to the sodium hydroxide solution in the stirring and grinding machine, and the temperature is controlled At 4°C, stir and grind at 60 rpm for 60 minutes to obtain the mixture, let it settle for 2 hours, wash and filter with ethanol, and dry to obtain a semi-finished product. Put the semi-finished product in a planetary ball mill and ball mill it at 50 rpm for 20 minutes to obtain zirconia powder. The obtained zirconia powder was calcined at 1050°C±5°C for 1.5h, and cooled naturally to obtain t-phase zirconia.

preparation example 2

[0045] The silicone resin is prepared from 18g of FM-7721 modified hydroxysiloxane, 49.6g of methanol, 32g of KR-242A silicone resin and 0.2g of diethylenetriamine.

[0046] The preparation method of silicone resin: add 0.05g of diethylenetriamine, 18g of FM-7721 modified hydroxysiloxane and 32g of methylphenyl silicone resin into the reaction kettle, pre-react at 65°C for 120s, cool down After reaching 4°C, add 49.6 g of methanol, stir at 80 rpm for 10 min, add 0.15 g of diethylenetriamine, and stir at 60 rpm for 2 min to obtain a finished silicone resin.

Abstract

The invention relates to the technical field of mica insulation products, in particular to a special-shaped mica insulation product suitable for three-dimensional modeling and a preparation method of the special-shaped mica insulation product. The invention discloses a special-shaped mica insulation product suitable for three-dimensional modeling. The special-shaped mica insulation product is prepared from organic silicon resin and mica slurry, the mica slurry is prepared from the following raw materials in parts by weight: 60 to 80 parts of white mica, 5 to 10 parts of biotite, 5 to 20 parts of fluorophlogopite, 2 to 5 parts of toughening filler, 0.5 to 3 parts of mica surface treating agent and 80 to 150 parts of organic solvent. The prepared special-shaped mica insulation product is good in mechanical strength and weather resistance and long in service life, and the application field of the mica product is expanded.

Description

technical field [0001] The present application relates to the technical field of mica insulation products, in particular to a special-shaped mica insulation product suitable for three-dimensional modeling and a preparation method thereof. Background technique [0002] The development of the new material industry has received more and more attention from the state. In recent years, the state has successively released new material industry, strategic emerging industry development plans and technological development plans. Insulating material is the material that isolates the charged body from other parts in electrical equipment. It is the key to ensure the long-term safe operation of electrical products, and it is the key material that directly affects the advanced level of technical indicators of electrical products. [0003] Mica is a lamellar structure composed of two layers of silicon-oxygen tetrahedron sandwiching a layer of aluminum-oxygen octahedron. It has extremely hi...
