The invention provides a method for extracting rubber colloid from rubber precipitation liquid and application, and relates to the technical field of rubber extraction. According to the method, the alkaline protease is firstly adopted to carry out enzymolysis on the gelatination liquid to obtain the enzymolysis gelatination liquid, then the bacterial liquid is adopted to carry out gelation on the enzymolysis gelatination liquid, and compared with a method of directly adopting the bacterial liquid to carry out gelation on the gelatination liquid, the method has the advantages that the addition amount of the bacterial liquid can be effectively reduced, and the gelation time is shortened; meanwhile, the quality of dry glue prepared by adopting the obtained rubber body is better than that of dry glue prepared by adopting a sulfuric acid gel process, the ammonia nitrogen content of water is relatively low, the production cost of an enterprise can be greatly reduced, the titer of a rubber product ...
