Preparation method and application of high-performance motor packaging material

Abstract

The invention relates to the field of motor packaging, in particular to a preparation method and application of a high-performance motor packaging material. The preparation method of the high-performance motor packaging material comprises the following steps: (1) preparing the resin A; (2) preparing a curing agent; and (3) performing an action process of the resin and the curing agent to obtain the high-performance motor packaging material, wherein the mass ratio of the resin A to the curing agent is 1: (0.7-1.3); the resin A in the step (1) is prepared from the following raw materials: 3, 4-epoxy hexyl methyl-3, 4-epoxy cyclohexyl formate, acrylic polyurethane resin, a toughening agent, a novel functional filling agent, an anti-settling agent and a coupling agent; raw materials for preparing the curing agent in the step (2) comprise methyl tetrahydrophthalic anhydride, polyether polyol, novel functional filling powder, an anti-settling agent and an accelerant. According to the motor packaging material, the modified powder is used as a filling material, so that the motor packaging material has the characteristic of large usage amount, and the cost can be reduced; and on the basis of using a large amount of filling powder, the motor packaging material with relatively good toughness, strength and temperature-resistant effect is prepared.

Description

A kind of preparation method of high-performance motor packaging material and its application Technical field: The present invention relates to the field of motor packaging, in particular to a method for preparing a high-performance motor packaging material and its application use. Background technique: [0002] With the development of society, people have higher and higher requirements for motor packaging; the potting material factory of the motor requires The following characteristics: It should have good fluidity before curing, and can penetrate into the uneven gap on the winding surface. After potting, the workpiece is outside. The surface should be smooth and flat, so that the motor has basically the same moment of inertia when rotating. Reduce the sudden change in speed and steering of the motor. The vibration caused by the sudden thermal change of mechanical stress during cooling reduces the resistance of the cooling medium to the rotating part of the motor. to...
