This invention discloses a single-component moisture-curing conductive and thermally conductive adhesive and its preparation process, comprising the following raw materials in parts by weight: 100 parts SMP adhesive; 15-30 parts flake silver powder; 500-900 parts spherical silver-coated copper powder; 0-400 parts dendritic silver-coated copper powder; 10-20 parts decamethyltetrasiloxane; 1-1.5 parts β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate isooctyl ester; 7.5-10 parts N-β-(aminoethyl)-γ-aminopropyltrimethoxysilane; and 1-1.5 parts vinyltrimethoxysilane. This invention allows the adhesive to cure at room temperature / low temperature using moisture in the air, eliminating the need for temperatures above 120°C. This completely avoids thermal stress damage to heat-sensitive substrates such as plastics, flexible circuit boards, and PET / PI films, making it perfectly suited for low-temperature processing scenarios such as flexible electronics manufacturing, wearable devices, and flexible sensors.

The utility model discloses an extension piece for a table edge, the table edge with the extension piece and a billiard table, and belongs to the technical field of billiard tables, after the extension piece is fixed to the longitudinal end of a backing batten of the table edge, the extension piece extends to the outer side of a steel plate, after the middle of an adhesive tape of the table edge is bonded to the backing batten, the end of the adhesive tape can be bonded to the extension piece, and at the moment, the extension piece is fixed to the outer side of the steel plate. The end portion of the rubber strip is bonded on the extending piece, the end portion of the rubber strip is supported, radian grinding can be carried out on the end portion of the rubber strip, radian grinding can be carried out without needing to be carried out after the wooden handrail and the steel plate are assembled, and production efficiency of the billiard table is improved. Moreover, after the adhesive tape is mounted and polished, one end of the table wool can be fixed between the steel plate and the wooden handrail, and the steel plate can be mounted once, so that the tedious process that the wooden handrail is mounted, dismounted and then mounted is avoided, and the production efficiency of the billiard table is improved.

This utility model discloses a power module heat dissipation module and an automotive power supply, relating to the field of automotive power supplies. The power module heat dissipation module includes a mounting assembly and multiple heat-generating devices. The mounting assembly includes a first circuit board and a second circuit board arranged opposite each other and spaced apart. The side of the first circuit board facing the second circuit board is a first mounting surface, and the side of the second circuit board facing away from the first mounting surface is a second mounting surface. The first end face of each heat-generating device is connected to either the first or second mounting surface, and the second end face of each heat-generating device is flush with the same plane. This utility model aims to simplify the water channel structure and reduce the risk of leakage.
