Magnetic conductive pressure-sensitive adhesive, preparation method thereof and magnetic conductive adhesive tape

Abstract

The invention provides a magnetic conductive pressure-sensitive adhesive which comprises the following components in parts by weight: 15-30 parts of 1,6-hexanediol diacrylate gel, 20-40 parts of 2-ethylhexyl acrylate, 18-36 parts of AA refined acrylic acid, 10-20 parts of 1-hydroxycyclohexyl phenyl ketone and 10-20 parts of dodecanethiol. The preparation method of the 1,6-hexanediol diacrylate gelcomprises the following steps: adding persulfate into a mixed solution of 1,6-hexanediol diacrylate and triethanolamine in a weight part ratio of 3 : (1-2), and uniformly mixing the components, so asto obtain the 1,6-hexanediol diacrylate gel. The UV light is used for treating the preparation process instead of heating, so that the processing mode is simple, the production is more energy-savingand environment-friendly, and the prepared pressure-sensitive adhesive has very strong weather resistance to high temperature and low temperature.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and relates to a magnetically conductive pressure-sensitive adhesive, a preparation method thereof, and a magnetically conductive adhesive tape. Background technique [0002] With the continuous iterative update of electronic products, consumer electronics and automotive electronic products are gradually moving towards the direction of high frequency, high current, low power consumption, low cost, and thinness. Power inductors have the characteristics of fast production speed, high degree of automation, and stable electrical properties. It has several advantages and is widely used in electronic products; but the magnetic core also has some defects: the adhesive is not evenly distributed after the product is glued, there is a gap between the copper wire and the magnetic glue, and there will be noise when passing the current, and the The power dissipation value of the type core is relatively larg...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the pressure-sensitive adhesive commonly used in electronic equipment in the prior art is complicated to package and cannot be torn off multiple times, and conducts in-depth research and development on the pressure-sensitive adhesive component formula and preparation method to obtain a high-viscosity adhesive. High-quality pressure-sensitive adhesive, the bonded magnetic conductor has a series of advantages such as firmness, wear resistance, small stress, high resistivity, insensitivity to temperature changes, and can improve the magnetic permeability of components.
