Embodiment 1-3 and comparative example 1-6

[0052] The softening agents of Example 1-3 and Comparative Example 1-6 were prepared respectively by adopting the above-mentioned segmented blending method, and the formula and quality test results of Example 1-3 and Comparative Example 1-6 are shown in Table 2 below. Analysis method Same as Table 1.

[0053] Table 2: The material proportion (wt%) of embodiment 1-3 and comparative example 1-6

[0054]

[0055] As can be seen from Table 2, embodiment 1-3 can meet quality index requirement. It can be seen that 60-65% of the extracted oil (the aromatic content is not higher than 20%), 20-25% of the pressed residue, 10-15% of the white oil and 2-2.5% of the EPDM rubber, using the above The rubber softener is prepared by stepwise blending method, and its density, viscosity, flash point, water content, volatile matter and CA value can all meet the quality index requirements in Table 1.

Abstract

The invention discloses a production method of a cleaning rubber softener. The method comprises the following steps: Step 1, first-stage blending: blending the first part of the extracted oil with pressed residue oil to obtain the first-stage blending liquid; 2. The second stage of blending: blending the white oil with the first stage of the blending liquid to obtain the second stage of the blending liquid; step 3, blending the pre-blended viscosity adjustment mother liquor with the second stage of the blending liquid, A clean rubber softener is obtained; the viscosity-adjusting mother liquor is a mixture of the second part of the extracted oil and EPDM rubber; the first part of the extracted oil and the second part of the extracted oil constitute the entire extracted oil. The production method of the present invention controls the mother liquor by synchronously configuring the viscosity of the EPDM rubber and the second part of the extracted oil, which shortens the processing cycle and reduces the production cost. Blending processing is safer and more environmentally friendly, no three wastes are generated, and the efficiency is high.

Description

technical field [0001] The invention relates to an industrial rubber additive, in particular to a production method of a novel cleaning softener used in the production of rubber products. Background technique [0002] During the use of rubber tires and other products, at a certain temperature, the harmful aromatic hydrocarbons in the softener in rubber products are emitted into the air, causing air pollution. After years of research, relevant foreign scholars believe that the content of aromatic hydrocarbons in the softener used in rubber products is 8-10% (CA value), and the comprehensive index is the most suitable. The so-called comprehensive index mainly refers to the best choice for the strength of rubber products and the degree of air pollution when the CA value of the content is 8-10%. Therefore, this kind of softener is called cleaning softener oil. [0003] The CA value in the softener oil is large (the general content is about 35%), which is beneficial to the mutu...
