Abstract

In order to overcome the problem of insufficient adhesion performance of existing UV-curable conformal adhesives, the present invention provides a high-adhesion UV-curable conformal adhesive, which includes the following components in parts by weight: 25-50 parts of modified trifunctional acrylate , 45-60 parts of active diluent, 3-6 parts of initiator, 1.5-10 parts of auxiliary agent. At the same time, the invention also discloses a preparation method of the above-mentioned high-adhesion ultraviolet-curable three-proof adhesive. The high-adhesion UV-curable conformal adhesive provided by the present invention improves the cohesion and polarity of the conformal adhesive by modifying the trifunctional acrylate, effectively improves the bonding adhesion and coating hardness of the conformal coating to the substrate, and improves protective effect.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a high-adhesion UV-curable three-proof adhesive and a preparation method thereof. Background technique [0002] UV curing technology is widely used in coatings, adhesives, microelectronics, dental restorations and biomaterials. UV-curable three-proof adhesive is a UV-cured electronic coating, generally made of low-viscosity and low-volatile resin, which can be used in selective spraying equipment, with waterproof and shock resistance, salt spray resistance, The breakdown strength is also stronger than other three anti-paints. Generally speaking, it only takes tens of seconds to quickly cure the UV-curable three-proof adhesive for circuit board protection. At the same time, the UV-curable three-proof adhesive is a solvent-free product. The composition does not contain VOC, which can avoid contact with various pollution sources during the assembly process. , such as...
