Abstract

The invention discloses a one-component ultraviolet-light-anaerobic dual-curing adhesive. The adhesive comprises the following active ingredients in percentage by weight: 40-50% of epoxy acrylate, 15-20% of polyurethane acrylate, 30-35% of acrylics reactive diluents, 1-2% of photoinitiator, 0.5-1% of oxidizing agent, 0.1-0.5% of reducing agent, 0.1-0.5% of polymerization inhibitor, and 0.5-2% of accelerator. The one-component ultraviolet-light-anaerobic dual-curing adhesive has the advantage of entirely solving the difficulty that the photocuring adhesive cannot be entirely cured at the shading parts. In addition, the adopted resin contains acrylate and double bonds. Through the one-component ultraviolet-light-anaerobic dual-curing adhesive, the photocuring reaction and anaerobic curing reaction are well combined, the reaction system is uniform, the curing property is excellent, the binding reliability is high, the energy resource can be saved, and the application range is wide.

Description

technical field [0001] The invention relates to an adhesive, in particular to a one-component ultraviolet-anaerobic dual curing adhesive and a preparation method thereof. Background technique [0002] Adhesives commonly used in the market currently include epoxy adhesives and UV-curable adhesives. [0003] Epoxy adhesives need to be prepared on-site. During the compounding process, a large number of mechanical air bubbles will be brought into the glue by fully stirring the compounding process, resulting in congenital technical defects in sealing and reliability. And the epoxy adhesive colloid is too hard and easy to crack. [0004] UV-curable adhesives have the advantages of single-liquid packaging, fast curing speed, and environmental protection. However, the use of UV-curable adhesives also has limitations, especially in terms of sealing. Because some light cannot be directly irradiated, such as non-transparent objects or complex geometric surfaces, curing is difficult t...
