Problems solved by technology
At present, the industry usually uses visual inspection for the detection of masterbatch dispersibility, that is, the inspector looks for the powder in the masterbatch. However, due to the similar color, the traditional detection method lacks intuition, and the detection accuracy is low, which affects product quality.

Embodiment Construction
[0009] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with illustrations and specific embodiments.
[0010] In the first step, carbon black is added to styrene-butadiene rubber at a ratio of about 1:60 (weight ratio) to make a mixed rubber, and the container containing the rubber is placed on the open mill, and the roller distance of the open mill is adjusted. For 4mm, perform triangular bagging and rolling for about 5 times each.
[0011] In the second step, a number of light-colored masterbatches than 30 are randomly selected as samples, and all samples are added to the mixed rubber prepared in step 1, and the roller distance of the open mill is kept, and the mixed rubber is rolled and rolled alternately. Triangle bag about 8 times, until the light-colored masterbatch glue that initially discolored the container spreads evenl...

The invention discloses a master batch dispersibility detection method. According to the detection method, the macro dispersibility of a master batch sample with light color is detected by utilizing the color difference between butadiene-styrene rubber added with carbon black and master batches. The method at least comprises the following steps: (1) adding carbon black into the butadiene-styrene rubber according to the proportion of 1 to 60 to prepare mixed rubber materials, carrying out triangular package and rolling on the mixed rubber materials, uniformly dispersing the carbon black and carrying out black dyeing on the butadiene-styrene rubber for later use; (2) randomly selecting a plurality of master batches with light colors as samples, adding all the samples into the mixed rubber materials prepared in the step (1), carrying out rolling and triangular package on the rubber materials alternatively until the mixed rubber materials are restored to be black; and (3) arranging the mixed rubber materials obtained in the step (2) on an open mill, rolling, and cutting the rolled mixed rubber materials into slices, judging the dispersibility of the samples is not qualified if the slices have particles with light colors under the irradiation of white light, and judging the dispersibility of the samples is qualified if the integral slices are uniformly black. The detection process is intuitive through the contrast colors generated by the carbon black.
Description
technical field [0001] The invention relates to a method for detecting the dispersibility of light-colored rubber masterbatch made by powder granulation technology. Background technique [0002] The masterbatch produced by powder granulation technology is one of the reasons that affect the quality of the masterbatch due to the aggregation of the main component powder. The powder exists in the form of small hard lumps and will not be dispersed during rubber processing. At present, the industry generally uses visual inspection for the detection of masterbatch dispersibility, that is, the inspector looks for the powder in the masterbatch. However, due to the similar color, the traditional detection method lacks intuition, and the detection accuracy is low, which affects product quality. Contents of the invention [0003] The object of the present invention is to provide a detection method for detecting the macroscopic dispersion of light-colored masterbatches, and the contras...
