Abstract

The invention provides a particle size analysis method for carbon black in acrylic rubber, which is characterized by comprising steps: (1) smashing acrylic rubber and adding a photocatalyst; (2) performing light irradiation treatment on the acrylic rubber obtained in step (1); (3) mixing the product obtained in step (2) with an alkali solution; (4) mixing the residual solid A in the solution in step (3) with an acid solution; (5) placing residual solid in the step (4) into a solvent for supersonic dispersing; (6) detecting the particle size of the carbon black in step (5). The detection method has the characteristics of accuracy and high operability.

Description

technical field [0001] The invention belongs to the technical field of material engineering and detection, and specifically refers to a method for testing the particle size of carbon black in rubber materials. Background technique [0002] Acrylate rubber (ACM) is a kind of high molecular elastomer polymerized by acrylate and vulcanization point monomer. It has high thermal stability, good oil resistance, small air permeability and good resistance Ozone, aging resistance and stress fatigue resistance and other properties. [0003] Carbon black is an important reinforcing agent for the composition of rubber materials, and its mechanical behavior is related to the distribution, particle size and carbon black content of carbon black particles. Carbon black with different particle sizes has different reinforcing effects on rubber. Generally speaking, the smaller the particle size of carbon black in rubber materials, the better the tensile strength, hardness and reinforcing prop...
