Low ammonia low protein concentrated natural latex production method

Abstract

The invention discloses a natural latex manufacturing method of low amino low protein condensing, which is characterized by the following: adding laurate amine in the fresh latex to do stable disposal; adding 0.06-0.6 g Alcalase 3.0T in fresh latex per kg; stirring continually for 1-2 h; proceeding 10-19 h silencing disposal; supplying ammonia at 0.20 percent in the centrifuged latex timely; adding 0.05-0.1 percent laurate amine simultaneously; adding equivalent perduren accelerant and zinc oxide at 0.02-0.05 percent; conserving; condensing the latex to 0.015-0.065 percent of total weight; adding 1-2 percent dodecyl sodium sulfate at wafer content counting; utilizing ionic water for the whole procedure.

Description

technical field

[0001] The invention belongs to a production method of low-ammonia and low-protein concentrated natural rubber latex, and specifically relates to the technology of using enzymes to decompose and remove the protein in the natural rubber latex, the natural latex is stabilized first, and chemical drugs inhibit enzymes. Background technique

[0002] The production of existing low-protein concentrated natural rubber latex, the common method is to adopt multiple centrifugation or biochemical methods, that is, directly add a kind of alkaline protease in the fresh latex, utilize enzymatic removal of the protein in the natural rubber latex, concentrate through centrifugation obtained by removing most of the protein. However, the stability of fresh latex and residual enzymes involved in the production process have a significant impact on the chemical stability of concentrated natural latex. The solution often adopts 0.7% high ammonia as a preservative, adopts various ...
