Abstract

The invention discloses a new energy thin-film capacitor polyurethane embedding adhesive and a preparation method thereof. The two-component polyurethane adhesive is prepared by mixing and curing a component A and a component A in the weight ratio of 1 to (3-6), wherein the component A is prepared from the following components in parts by weight: 20 to 30 parts of castor oil, 10 to 20 parts of polycarbonate diol, 50 to 70 parts of filler and 2 to 5 parts of aid; the component B is a curing agent. The two-component polyurethane adhesive has high wear resistance, high low temperature resistance, high strength, high elongation, large load support capacity, high oil resistance, high bonding property, high shock absorbing capability and large hardness adjusting range, and has the characteristics of high heat resistance, environmental friendliness, flame retardance and high heat conductivity which are not owned by an ordinary polyurethane adhesive. The new energy thin-film capacitor polyurethane embedding adhesive has a potential use value and a development prospect in the field of electronic element embedding materials.

Description

technical field [0001] The invention belongs to the field of potting materials for new energy thin film capacitor electronic components, and relates to a new energy thin film capacitor polyurethane potting glue and a preparation method thereof. Background technique [0002] With the national environmental protection strategy and the promotion of new energy development, film capacitors are developing towards high-power, high-frequency and other high-performance. At present, the polyurethane potting adhesive potting capacitors used in the market generally have poor durability when the power is on, and poor high temperature and high humidity resistance for a long time when the power is not on, and the flexibility of the colloid itself needs to be strengthened. The product Poor stability, etc., have been unable to meet the requirements of new energy film capacitors. [0003] The invention mainly selects the types and proportions of various materials in the two-component polyure...
