Embodiment 1～7 and comparative example 1～3

[0044] At normal temperature and pressure, add the reactive diluent into the container according to the components specified in Table 2 and mix evenly; then slowly add oligomers, tackifying resins, mercaptans, vacuum glass micro Stir the ball at the same time to prevent agglomeration until the oligomer and reactive diluent are completely dissolved into a uniform liquid; then add photoinitiator and thermal initiator to the container, heat to 50°C, and stir at the same time until the photoinitiator is completely Dissolve into a uniform liquid; then add ultraviolet absorber and dispersant to the container and continue to stir for 2 hours, after standing still for 1 hour, the sampling test is qualified, and the adhesive of each embodiment and comparative example is made by filtering. During the production process, it is necessary to pay attention to moisture-proof and light-proof.

Abstract

The invention discloses a dual-curing adhesive and an adhesive tape. The dual-curing adhesive comprises the following raw materials in parts by weight: 10-50 parts of reactive diluent, 30-90 parts of oligomer, 1-20 parts of tackifying resin, 1-5 parts of mercaptan, 1-7 parts of photoinitiator and 1-5 parts of thermal initiator. The adhesive has better adhesion strength and ageing resistance and adopts a dual-curing manner; the thermal initiator is added in a formula and performs thermal initiation by using heat generated by photocuring; and the problem of difficult irradiation, and difficult curing in a deep layer due to the thick adhesive can be improved. Vacuum glass microspheres are added into the adhesive; the adhesive has sound-proof and shock absorbing effects; compared with the traditional foam adhesive tape, the adhesive has more excellent performance and wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a dual-curing adhesive and adhesive tape. Background technique [0002] At present, various tapes have become indispensable items in industries such as electronics, electrical appliances, hardware, advertising, construction, and solar photovoltaics. Applications in the above fields place high demands on the adhesive tape itself. For example, it must have a super strong adhesive function. Whether it is a slippery plastic surface, a mirror-smooth metal, a glass surface, or an uneven wall surface, it can stick the items to be fixed very firmly, which can effectively reduce the risk of damage. Weight, replace screws, rivets, welds, hold and seal at the same time. In addition, anti-ultraviolet radiation, anti-solvent, anti-high temperature, and anti-ultra-low temperature difference are also required. [0003] With the rapid development of my country's economy, the dem...
