Quick-curing adhesive and preparation method thereof

Abstract

The invention discloses a quick-curing adhesive and a preparation method thereof. The quick-curing adhesive is prepared from phenol, 37% formaldehyde, 86% polyformaldehyde, NaOH, H2O, silane coupling agent and phenolic resin curing agent. When the quick-curing adhesive disclosed by the invention is used for preparing an emery cloth grinding tool, the curing drying technique can be implemented after directly drying for 2 hours. Compared with the traditional technique, the invention greatly shortens the curing time, saves the investment into the curing oven, cancels the aging treatment, enhances the work efficiency in production and saves the manpower, thereby greatly shortening the production cycle of the product, achieving the goal of greatly lowering the product cost, enhancing the market competitiveness of the product and improving the economic benefit; and meanwhile, the invention can save electricity, steam, water, coal and the like, and make contributions in the aspects of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to an adhesive and a manufacturing method thereof, in particular to a fast-curing adhesive and a manufacturing method thereof. Background technique [0002] my country's coated abrasive manufacturing industry currently uses ordinary binders, including animal glue, semi-resin binders, and full-resin binders. The main problem with the above binders is that the manufacturing cost is high, especially It is used in the manufacture of abrasive tools. After the product comes off the production line, it needs to go through a curing and drying process for 72 to 76 hours, and then it needs to be aged for about one week. Therefore, in the application of the above adhesives in the manufacture of emery cloth abrasive tools, the process route is long, which wastes a lot of money, energy and manpower, and makes the manufacturing cost high. Contents of the invention [0003] In order to solve the above problems, the present invention provides a...
