Abstract

The invention discloses a latex extraction device with an extremely strong electric field. The latex extraction device consists of positive and negative plates, a spray cleaning device and a drying device; the positive electrode is composed of a conveying device with a conductive material attached to the surface; and the cathode consists of a conductive electrode plate. The method for extracting the latex by the extremely strong electric field is a method for continuously extracting the latex by constructing the extremely strong electric field, and comprises the following steps of: feeding the latex into an extremely strong electric field latex extracting device from a latex inlet, adjusting direct-current voltage, and adjusting the minimum distance between two poles of the extremely strong electric field; extracting the latex by the extremely strong electric field to obtain residual liquid and a rubber sheet on the other side; and continuously discharging the rubber sheet condensed on the positive electrode roller through a traction device. The method is simple in process, the obtained rubber is excellent in performance, meanwhile, rubber components are completely reserved, no flocculation process exists, the method is environmentally friendly, and the cost is saved. The method has the advantages of few human influence factors, realization of continuous production, stable product quality, low energy consumption, high extraction efficiency, and easiness in industrial research.

Description

technical field [0001] The invention relates to a device for extracting latex by an extremely strong electric field, which simultaneously solves key problems such as automatic production, acid flocculation, waste glue treatment, etc., 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 production of solid rubber such as natural rubber and styrene-butadiene rubber is generally a positive flocculation process in which the flocculant is poured into the latex and waits for the latex to coagulate. The positive flocculation equipment has a simple process, but due to its long-term coagulation process, the quality of the product is not easy to obtain. control, the product is unstable; the positive flocculation process has many shortcomings that...
