Embodiment 1-3 and comparative example 1-6

[0050] 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.

[0051] Table 2: The material proportion (wt%) of embodiment 1-3 and comparative example 1-6

[0052]

[0053] 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 cleaning rubber softening agent. The cleaning rubber softening agent comprises the following raw materials in percentage by weight: 60%-65% of extract oil, 20%-25% of vacuum residue, 10%-15% of white oil and 2%-2.5% of ethylene-propylene-diene monomer rubber, wherein the content of aromatic hydrocarbon in the extract oil is not higher than 20w%. According to the cleaning rubber softening agent, waste oil which is low in cost and wide in source is utilized as basic oil of, so that the cost is low, and the energy is saved; by selecting ethylene-propylene-diene monomer rubber aggregates, the viscosity can be conveniently and substantially adjusted, so that the cycle of a rubber vulcanization process is shortened, and the cost is further shortened; as the CA value is maintained within 8%-10%, and the strength and the service life of a rubber product are not influenced.

Description

technical field [0001] The invention relates to an industrial rubber additive, in particular to a new type of 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 mutual solubility of ...
