Abstract

The invention provides a method for producing a rubber matrix Chinese medicine plaster based on Mooney viscosity. The method comprises the steps that: natural rubber or synthetic rubber plasticated into slice is placed in an internal mixer, a filler, a viscosifier, a softener and a Chinese medicine extract are added in accordance with the formulation of the rubber matrix Chinese medicine plaster for mixing, the internal mixer is shut off and samples are taken for analyzing the value of Mooney viscosity of the mixed plaster, the mixing time is controlled in a range from 4 to 25 minutes so thatthe Mooney viscosity of the mixed plaster, measured by a Mooney viscosity apparatus, is from 3 to 9; refining is then implemented, the mixed plaster is rolled 1 to 6 times on a mixing mill or milled for 1 to 5 minutes in the internal mixer, and the Mooney viscosity of the sampled plaster after the refining, measured by the Mooney viscosity apparatus, is from 2 to 7 by controlling the rolling timesor the milling time. According to the method, the Mooney viscosity of the rubber plaster in different production steps is regarded as quantitative indicators in order to monitor the production of therubber plaster on the scene, thus ensuring the coating and adhesive performance of the rubber plaster article.

Description

technical field [0001] The invention relates to a production method of a traditional Chinese medicine plaster, in particular to a production method of a rubber matrix traditional Chinese medicine plaster based on Mooney viscosity. Background technique [0002] At present, the production process of traditional Chinese medicine rubber ointment is divided into two kinds: traditional process (solvent method) and new process (hot pressing method). The production process of the solvent method needs to use a large amount of solvent-gasoline, the production cost is high, the requirements for explosion-proof and fire-proof measures are strict, the safety hazard is large, and the residue of gasoline is easy to cause skin allergies. Cause more loss of volatile components. The hot pressing method overcomes the shortcomings of the solvent-based rubber paste, does not require solvents, is safe in production, meets environmental protection requirements, has low production costs, and has a...
