Abstract

The invention provides threaded hole protection glue and a preparation method and application thereof. The threaded hole protection glue is prepared from the following components in percentage by mass: 15 to 20 percent of 2-acrylamide-2-methylpropanesulfonic acid, 16 to 23 percent of amide monomer, 15 to 20 percent of acrylate, 5 to 8 percent of trehalose, 10 to 20 percent of transparent powder, 0.5 to 2 percent of fumed silica and 2 to 3 percent of initiator. The preparation method comprises the following steps: mixing 2-acrylamide-2-methylpropanesulfonic acid, trehalose and water to obtain a mixture A; mixing the mixture A, fumed silica and transparent powder to obtain a mixture B; then mixing the mixture B, an amide monomer and acrylate to obtain a mixture C; and mixing the mixture C with an initiator to obtain the threaded hole protection glue. The threaded hole protection glue provided by the invention is resistant to high temperature, odorless, non-toxic, environment-friendly and safe, and can meet the processing requirements of surface treatment of structural parts of precise electronic products.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a threaded hole protective adhesive and its preparation method and application. Background technique [0002] With the development of society, many industries need to temporarily bond or protect materials under the limitation of technological conditions. For example, when a process needs to position the material or damage the material, UV glue can be used to bond or protect the material. After the process is completed, the UV glue is taken out and the next process is carried out. Due to the different processes, there are also various needs for temporary bonding or protective colloids. [0003] For example, the structural components of electronic products such as laptops, charging treasures, and mobile hard drives are often made of hard aluminum alloys. The screw holes on such structural components have the characteristics of small openings, low aperture ratio, and ...
