Abstract

The invention provides an anti-static polyurethane pouring sealant and a using method thereof. The anti-static polyurethane pouring sealant comprises the following components in parts by weight: 40 to 50 parts of polyisocyanates, 60 to 72 parts of polyhydric alcohols, 2 to 2.4 parts of oxidized graphene, 67 to 80 parts of a filler and 0.05 to 0.08 part of a catalyst. The using method comprises the following steps: after all components of the anti-static polyurethane pouring sealant are mixed, pouring an object to be poured, and then curing the object to be poured at the temperature of 20 to 30 DEG C for 24 to 48 h to form a sealant block. The anti-static polyurethane pouring sealant provided by the invention has good mechanical performance after being cured, has relatively high insulation performance and anti-static performance, and is particularly applicable for pouring of electrical apparatus elements.

Description

technical field [0001] The invention belongs to the technical field of potting glue, and in particular relates to an antistatic polyurethane potting glue and a using method thereof. Background technique [0002] With the widespread popularization of electronic products, LED lighting and outdoor light art works, the components are becoming more and more small in size and highly integrated, resulting in smaller and smaller wire spacing, thinner and thinner insulating films, and improved electrical breakdown resistance. Also getting worse. However, the electrostatic voltage accumulated by electronic products in the process of production, storage and transportation far exceeds its breakdown voltage threshold (for example, the withstand voltage threshold of LED blue light wafers is only more than 1000 volts, and it is easy to be broken down by static electricity). It may cause breakdown or failure of the device, reduce its reliability and bring safety hazards. [0003] Potting ...
