Abstract

The invention provides a water vapor resistant composition. The water vapor resistant composition comprises 50-55 parts of epoxy resin; 0.1 to 10 parts of a water vapor resistant component; 30 to 46 parts of an active diluent; 0.5 to 3 parts of a photoinitiator; 0.1 to 2 parts of a photo-initiation auxiliary agent; 1-5 parts of other assistants. The moisture-resistant composition takes epoxy resinas a main component, the epoxy resin and a reactive diluent form macromolecules with high crosslinking density under the activation of a photoinitiator and a photo-initiation aid, the macromoleculesfurther have a synergistic effect with a moisture-resistant component, each molecule of the moisture-resistant component at least contains one group which reacts with hydroxyl, and the group can be combined with hydroxyl formed by ring opening of the epoxy resin, so that the cross-linking effect between the moisture-resistant component and the epoxy resin matrix is promoted, the compactness of thematerial is improved, the waterproof performance of the obtained water-vapor-resistant composition is enhanced, it is guaranteed that water molecules cannot penetrate the water-vapor-resistant composition, and the water vapor isolation effect of the water-vapor-resistant composition is improved.

Description

technical field [0001] The application belongs to the technical field of chemical materials, and in particular relates to a water vapor resistant composition and a preparation method thereof. Background technique [0002] With the rapid development of the electronics industry, electronic equipment is developing in the direction of miniaturization, high capacity and high performance, and the high integration and ultra-thinning of electronic components have become a trend. It must be done. [0003] The sealant for electronic appliances is produced by the condensation reaction of moisture in the air to release low molecules to cause cross-linking and curing, and vulcanize into high-performance elastomers. It has excellent resistance to alternating cold and heat, aging resistance and electrical insulation. And has excellent insulation, moisture-proof, shock resistance, corona resistance, leakage resistance and chemical medium resistance. At the same time, since the water vapo...
