Abstract

The invention discloses an instant adhesive primer and a preparation method thereof, and the preparation method comprises the following steps: in a nitrogen or argon environment, under a stirring condition, mixing fluoride, methylsiloxane and an amino compound, heating to 50-60 DEG C, adding an ionic liquid, uniformly stirring, and cooling to room temperature to obtain the instant adhesive primer, the amido compound is an organic amine-glycidyl ether adduct, and the preparation method of the amido compound comprises the following steps: stirring organic amine and glycidyl ether at 58-60 DEG C for at least 4 hours in an inert environment atmosphere, and cooling to room temperature to obtain the amido compound, the fluoride, the ionic liquid and the amino compound are matched to serve as the primer of the instant adhesive, so that the curing speed of the instant adhesive is higher, the strength and the toughness are improved, and the cured adhesive layer is free of whitening phenomenon.

Description

technical field [0001] The invention belongs to the technical field of instant dry glue, in particular to an instant dry glue primer and a preparation method thereof. Background technique [0002] The main component of cyanoacrylate is α-cyanoacrylate monomer, which can be cured in a few seconds by anionic polymerization under the action of an initiator to complete the firm bonding of the two interfaces. Usually, cyanoacrylates are one-component, low-viscosity, fast-curing under normal temperature conditions, and have high bonding strength to metals, glass, rubber, plastics and other materials. Due to its simple use, fast curing speed, high bonding strength and relatively cheap price, instant adhesive has a wide range of applications and is especially suitable for use in the electronic assembly industry with a high degree of automation. [0003] In the electronic assembly industry, the pursuit of high production efficiency requires instant adhesives to have faster curing sp...
