Description
Technical field
The present invention relates to technical field of rubber preparation, more particularly to a kind of extracting method of natural rubber.
Background technology
Natural rubber typically refers to the Heveatex gathered from Para rubber tree, through manufacturing procedures such as supersolidification, dryings
And manufactured elastic decorating film.There are about 2000 kinds of different plants in the world can produce the polymer of similar natural rubber, from
Different types of rubber is obtained in wherein 500 kinds, but really with practical value is Brazilian para ruber.The table of rubber tree
When face is cut open, the latex dust in bark is cut off, and latex flows out from tree.The latex gathered from rubber tree, after dilution
Acid coagulation, washing, then tabletting, drying, packing, that is, commercially available natural rubber is made.The acquisition master of present natural rubber
Still to be commonly called as tapping rubber by manual operations, but this manipulation strength is big, and working environment is severe, and inefficient, therefore
With the demand in many markets, the trend of mechanized operation is not met yet.
The content of the invention

Obtain natural rubber.
To reach above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of extracting method of natural rubber, comprises the following steps：
（1）The branches and leaves of fresh rubber tree are chosen, taking off and wrap saw and take to sentence the branches and leaves of rubber tree saw prevents latex
Loss；
（2）Pulverization process is carried out to the branches and leaves of rubber tree using pulverizer and obtains rubber tree powder, by rubber tree powder and alkali
Property mixed liquor mixing after stand；
（3）Rubber tree powder after standing is filtered with alkaline mixed solution, is homogenized；
（4）Centrifugal treating is carried out to homogenate using centrifuge, the top layer suspension after centrifugation is rubber debris；
（5）Diafiltration is carried out to rubber debris using absolute ethyl alcohol, tabletting, dry i.e. acquisition rubber after diafiltration.
Further, step（1）In, the saw of the branches and leaves of rubber tree takes to be carried out in fine day.
Further, step（2）In, alkaline mixed solution is the nitrite of 0.1% concentration.
Further, step（2）In, the time of standing is 24 ~ 48 hours.
Further, step（3）In, the mesh number of filtering is 10 ~ 20 mesh.
Further, step（4）In, the rotating speed of centrifugal treating is 1200 ~ 6000r/min.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention provides a kind of extracting method of natural rubber, energy
Enough realize the saw of rubber tree branch take, crush and produce in mixed liquor centrifugation etc. mechanized operation, can realize natural
Rubber system standby mechanization and automation, so as to save artificial, raising speed, increase yield.
