Problems solved by technology

Double-sided adhesive gaskets usually require manual lamination, which consumes a lot of manpower and material resources, and has low production efficiency and high cost
Although the hot-melt adhesive process uses machine construction instead of manual lamination, the machine needs to be heated to 120°C during construction, and it needs to be left for at least 24 hours before it is completely dry after dispensing. Production requires a lot of space for storage

Abstract

The invention relates to a waterproof sealant as well as a preparation method and an application thereof. The waterproof sealant is prepared from components in parts by mass as follows: 30-70 parts of ultraviolet curing resin, 4-10 parts of a photoinitiator, 10-40 parts of a reactive diluent, 2.5-5.5 parts of a thixotropic agent, 1-4 parts of a coupling agent, 0.5-8 parts of an aid and 0.2-3 parts of a pigment, wherein the ultraviolet curing resin is one or more of polycarbonate polyurethane acrylate, polybutadiene polyurethane acrylate, polyester acrylate, modified epoxy acrylic resin and organic silicon acrylic resin. The waterproof sealant has better sealing and waterproof performance, can replace a traditional hot melt adhesive process or sealing washer after being applied to the sealing and waterproof field of electronic products and can significantly improve the production efficiency and reduce the cost.

Description

technical field [0001] The invention relates to the technical field of sealing and waterproof glue, in particular to a sealing and waterproof glue and its preparation method and application. Background technique [0002] In recent years, the role of electronic products in our lives has been increasing. People rely on electronic products for basic necessities of life, such as digital cameras, laptops, smart phones, removable storage devices, etc. The core components of electronic products are composed of electronic components, but electronic components are particularly sensitive to water. Once in contact with water vapor, they will be burned instantly under the condition of power on. There are many potential factors in our daily life that will cause damage to electronic products. harm. [0003] Modern electronic equipment requires small size, light weight, strong function, and compact structure, etc. The requirements for waterproofing of electronic products are increasingly ...
