Embodiment 1

[0036] Take 1 mol of 1-phenyltrichlorosilane, 0.1 mol of dimethyldichlorosilane, 0.5 mol of methylvinyldichlorosilane, 0.2 mol of diphenyldichlorosilane, and 0.2 mol of hexamethyldisiloxane at 10°C Add the organosilicon monomer dropwise to the flask with rapid stirring at a speed of 5L / min under certain conditions, and the dropwise hydrolysis reaction lasts for 4 hours, then reflux concentration and aging reaction at 120°C for 4 hours, and then wash with water until neutral , vacuumize the upper paint layer to remove solvent and low boiling matter, and take samples to measure the viscosity. When the viscosity reaches the target range, stop heating, cool to below 60°C and discharge to obtain component A. After NDJ-79 rotational viscosity Meter (Wuhan Glamo Testing Equipment Co., Ltd.) measures the viscosity of component A as 8120CP / 60°C.

Abstract

The invention relates to the field of paint chemical industry, in particular to an organosilicon impregnating paint and its preparation method and application. The tensile strength of the cured product of the organosilicon impregnating varnish is above 15MPa, preferably in the range of 15-20MPa, and the bending strength of the cured product of the organosilicon impregnating varnish is above 25MPa, preferably in the range of 25-35MPa. The mechanical strength of the organosilicon impregnating paint of the invention has been greatly improved.

Description

technical field [0001] The invention relates to the field of paint chemical industry, in particular to an organosilicon impregnating paint and its preparation method and application. Background technique [0002] Silicone material is currently a general-purpose insulating material variety, widely used in impregnating varnishes, coatings, mica tape adhesives, etc., but silicone materials have their own defects, and the problem of low mechanical strength of the cured product has been criticized. [0003] Silicone hydrosilicon addition silicone paint products are a large class of products in the silicone system, which obtain the final cured product through the addition reaction between silicon vinyl and silicon hydrogen, usually made of silicon vinyl Components and silicon hydrogen components, in order to obtain a suitable paint viscosity, for example, to obtain a paint viscosity of 1000CP, generally use the silicone vinyl component and silicon hydrogen component to achieve a v...
