Problems solved by technology

Among the existing detection technologies for coated abrasive products in China, there is a detection method of "glue or phenolic resin adhesion" which has the following deficiencies: 1. There is no standardized and unified detection method and detection conditions, The data is inaccurate; 2. It only involves the detection of the adhesive force with hide glue or phenolic resin; 3. It is limited to the detection of the adhesive force of the cloth base

Embodiment 1

[0010] This embodiment is a method for testing the 90° peel strength of coated abrasives, and the tools used are iron plates, universal tensile machines and clamps. The adhesive is epoxy resin, and the epoxy resin is a mixture of E51 and 650. Materials and specifications: Abrasive belt sample strip 22cm*8cm. Environmental conditions: 25°C±1°C.

[0011] (1) Preparation: Cut the tested coated abrasive product into 22cm long and 8cm wide sample strips, then prepare epoxy resin adhesive, mix E51 and 650 curing agent according to 1:1, stir evenly, stand-by;

[0012] (2) Sample preparation: Evenly coat the prepared epoxy resin on the iron plate, then paste the tested coated abrasive sample strip with the sand side down on the iron plate, cover with a piece of plastic film, and use another One iron plate is aligned and pressed on the sample strip covered with plastic film, and finally the two iron plates are fixed with adhesive tape, and put into an oven to cure at 115°C / 180min; a...

Abstract

The invention relates to a method for testing the peeling strength of a coated abrasive tool, comprising the following stepsof sticking a coated abrasive tool sample on a base plate by using adhesives; solidifying and then fixing the base plate stuck with the coated abrasive tool sample by using a clamp; and then testing the average force required for peeling the coated abrasive tool sample from the base plate. The invention standardizes the test method and the test standard, and the average value of data is accurate and has repeatability; the invention has wider test range including coated abrasive products, fabricbase material, paper base material, plastic base material and the like; and with the method, not only the adhesion performance of different adhesives and base materials can be compared, but also the final adhesion performance of different coated abrasive tool products can be directly known, so that the method is universal and practical.

Description

technical field [0001] The invention relates to a method for testing the peel strength, in particular to a method for testing the peel strength of coated abrasives. Background technique [0002] The application conditions and environments of coated abrasive products are different. For example, in the application of heavy-duty grinding and high-speed grinding, the grinding conditions and environmental requirements are strict, and the local temperature of grinding can reach 350 ° C. s. In heavy-duty grinding, high-speed grinding and applications that require surface effects on the ground workpiece, coated abrasive products are required to have good bonding properties to avoid failure of the adhesive in harsh environments such as high temperature or high speed It will cause the abrasive to fall off, which will affect the service life of the product and the surface effect of the grinding workpiece. Therefore, in the production of coated abrasives, it is necessary to detect the...
