preparation example Construction
[0018] The present invention also provides a preparation method of an insulating wax composition, the preparation method comprising: mixing rice bran wax, candelilla wax, montan wax, thickener, petrolatum, nano-mica powder and polyacrylic acid, heating and stirring ;
[0019] Wherein, relative to 100 parts by weight of rice bran wax, the consumption of the candelilla wax is 30-45 parts by weight, the consumption of the montan wax is 20-35 parts by weight, and the consumption of the thickener is 7-45 parts by weight. 13 parts by weight, the consumption of the petrolatum is 8-15 parts by weight, the consumption of the nano mica powder is 12-16 parts by weight, the consumption of the polyacrylic acid is 5-7 parts by weight; the thickener is selected from One or more of methylcellulose, hydroxypropylmethylcellulose and hydroxyethylcellulose.
[0020] In the present invention, the particle size of the nano-mica powder can be selected in a wide range, as long as it reaches the nano...
Embodiment 1
[0030] Mix 100g of rice bran wax, 35g of candelilla wax, 25g of montan wax, 10g of methylcellulose, 11g of petrolatum, 14g of nano-mica powder and 6g of polyacrylic acid at 25°C for 20min, then heat and stir at 120°C for 2.5h. Insulating wax composition A1 was obtained. Wherein, the particle size of the nano mica powder is 8nm, the weight average molecular weight of the polyacrylic acid is 2500, the melting point of the rice bran wax is 80°C, and the dropping point of the vaseline is 55°C.
[0031] The dropping melting point, kinematic viscosity, volume resistivity and corrosion detection results of the insulating wax composition are shown in Table 1.
