Abstract

The invention discloses a magnetic material adhesive and a processing method thereof, which is characterized in that the magnetic material adhesive is made of the following components in parts by weight: 97% of ethyl α-cyanoacrylate, diphthalic acid di Allyl ester 2.8-2.9%, phthalic anhydride 0.01-0.03%, phenylmethylsulfonic acid 0.07%-0.1%, triethyl citrate 1-4%. Compared with the magnetic material glue of the conventional technology, the magnetic material products processed with the magnetic material glue of the present invention can remove the primer in a short period of time by using alkaline water cooking material and will not leave edge imprints on the surface of the magnetic material product , spots and other defects, greatly improving production efficiency and reducing the consumption of manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a magnetic material adhesive and a processing method thereof. Background technique [0002] The processing of existing magnetic products usually adopts a slicing process. The slicing process usually needs to first bond the magnetic blanks together with magnetic glue, and then slice the bonded blanks to obtain magnetic products. After the slicing process, multiple magnetic material products are bonded together. In order to obtain each independent product, the magnetic material glue needs to be melted to separate the bonded magnetic material products. [0003] Existing magnetic material adhesives are usually synthetic adhesives, including main agents and auxiliary agents. The main agent is the main component of the adhesive and dominates the adhesive performance of the adhesive. The auxiliary agents include flame retardants, curing agents, Stabilizers, thickeners, foaming agents...
