Abstract

The invention discloses a method for preparing high-performance natural rubber through a biological coagulation technology. The method comprises the steps of fresh latex symbiotic microorganism solidification, extruding dehydration, crepe pressing, cleaning, granulation, drying and packaging. According to the fresh latex symbiotic microorganism solidification technology, cultured symbiotic bacteria solidification liquid and fresh latex are mixed and placed into a constant-temperature solidification box for constant-temperature solidification, and steps are executed, and finally the high-performance natural rubber is obtained. Mass industrial production can be achieved, and rapid odorless solidification of latex is achieved; due to rapid biological solidification, little non-rubber matter of natural rubber latex is decomposed, it is ensured that the chemical and physical properties of a solidified white gelatinous lump are quite high, strain induced crystallization can easily occur on the obtained high-performance rubber, and therefore the high-performance rubber has quite high autohension, good green strength and excellent processing performance.

Description

technical field

[0001] The invention relates to the technical field of accelerating the coagulation of natural fresh latex through the action of microorganisms, in particular to a method for preparing high-performance natural rubber by adopting biological coagulation technology. Background technique

[0002] The milky white liquid obtained from the rubber tree after rubber tapping is called latex. The latex that has just been harvested is also called fresh latex. The processing technology of these latex is the processing of natural rubber, and the final product of natural rubber processing is the corresponding number. Glue, to the processing of latex, the first step is actual coagulation, only the latex after solidification just has the condition of follow-up processing, and the latex after solidification is collectively referred to as white gel piece, and the coagulation mode of prior art has following several, the first In order to add acid to realize chemical coagulation,...
