Method for preparing high-performance natural rubber through biological coagulation technology

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,...

Problems solved by technology

This patented technology improves the combination of flora, but the flora in this patent still cannot get rid of the problem that the nutrients needed by the flora are obtained from fresh latex after the flora is implanted in fresh latex, and the microbial use solution still needs to be added Molasses, thus bring a large amount of fatty acids and ash in fresh latex, cause the quality of fresh latex to decline, still do not solve essential problem, how to obtain the high-quality white gel block of rapid solidification, if can't obtain high-quality white gel block, the income of rubber farmers and the operating income of natural rubber processing enterprises are difficult to increase again

[0008] The Chinese patent of patent number CN200910261009.7 is a method for coagulating natural rubber latex using microbial culture fluid. The present invention forms a microbial culture fluid containing a large number of viable bacteria through microbial fermentation of acetic acid bacteria and yeast as the main flora; The culture medium is mixed with a small amount of ethanol, acetic acid, sugar source, inorganic salt, etc. and added to the rubber latex, and the microorganisms such as acetic acid bacteria and yeast in the microbial culture medium use the nutrients in the rubber latex to produce acetic acid and bacterial cellulose to further promote the coagulation of latex particles , At the same time, microorganisms decompose and absorb a large number of nutrients such as nitrogen sources in latex during the growth process, thereby further reducing the total solid content of coagulation waste liquid, thereby reducing pollution emissions, and finally the whey left after squeezing the coagulation latex can be used as microbial The culture medium of the coagulation solution may be used as a beneficial micro-ecological preparation to realize the comprehensive utilization of rubber latex; this method is simple to operate, reduces costs, reduces pollution, and improves rubber production, and the physical and chemical properties of the product produced by the method are better than those of acid coagulation. The performance is good. This patent has the same problem as the patent No. CN201510006167.2, which uses a combination of microorganisms to coagulate natural rubber latex. That is, exogenous nutrients need to be added to the culture solution, and the problem caused by adding less exogenous nutrients is eventually caused. Bacteria decompose a large number of sugars and proteins in fresh latex to achieve their own reproduction. I personally think that as long as an appropriate amount of exogenous nutrients are added, high-quality white gel blocks can be obtained, but it is deceptive.
