Abstract

The invention discloses a method for extracting latex with a deformable roller with a super-strong electric field. A latex extracting device with the super-strong electric field comprises a deformablethin film roller as a positive electrode and a conductive electrode plate as a negative electrode, the latex is put into a continuous latex extracting device through latex inlets in two sides and isthen extracted electronically by adjusting direct-current voltage, latex bars flocculated on the positive electrode are continuously introduced into a washing pool to wash through a traction apparatus, and then the washed latex bars are dried and packed to obtain finished products. The method for extracting the latex with the deformable roller with the super-strong electric field has the advantages that a technology by using a latex extracting device with the super-strong-electric-field is simple, equipment is efficient and low in energy consumption, obtained rubber is excellent performances,a rubber constituent is preserved completely, a flocculation process is omitted, green and environmental protection are realized, cost is saved, anthropogenic influences are less, continuous production can be realized, product quality is stable, and industrialized studying is facilitated.

Description

Technical field [0001] The invention relates to a method for extracting latex from a deformable roller with a strong electric field, and simultaneously solves the key problems of automatic production, acid flocculation, waste glue treatment and the like. And it improves the extraction efficiency of the previously used uniform electric field device and reduces the energy consumption of extraction. The rubber obtained by the method is mainly used in the fields of car tread rubber, engineering tread rubber and the like. Background technique [0002] The surface of rubber particles is composed of lipids and charged proteins. These components have good hydrophilicity, so they can form a function similar to a protective layer so that the latex can maintain a stable colloidal state. Based on this principle, if the function of this protective layer can be lifted, the latex can be gelled or solidified. [0003] Acid coagulants, inorganic salt coagulants, and microbial coagulants can all d...
