Abstract
The present invention relates to auxiliary biological crude rubber latex solidifying process during rubber processing. The present invention has the technological points of: ensuring the purity of collected crude rubber latex via processing barrel washing water alone; adding few ammonia less than 0.03 %; adopting coagulant comprising sodium alkylbenzene sulfonate in 0.1-0.3 wt% of dry rubber and white sugar in 0.6-0.8 wt% and with the amount decreasing with the environment temperature over 15 deg.c; and the coagulation mechanism converting from natural fermentation to catalytic fermentation. The present invention has the beneficial effect of raising the tensile strength of product to over 22 MPa, being higher than that for radial ply tyre and aviation tyre.
Description
Technical field
The present invention relates to the auxiliary biological coagulation production method of former latex of natural rubber preliminary working.

At present, the main products of China's natural rubber is No. five standard rubbers, and its output accounts for 80% of ultimate production.The appearance color of this kind is good, the degree of cleaning height, but its physical and mechanical properties especially the tensile strength of rubber be difficult to satisfy the Technology requirement that radial glue or aircraft tyre glue are produced.
Summary of the invention
The purpose of this invention is to provide a kind of auxiliary biological coagulation production method of former latex that can improve the natural rubber tensile strength effectively.
The technical solution adopted for the present invention to solve the technical problems is:
1. invention technical essential
A. guarantee the pure collection of fresh latex, wash water is handled in addition;
B. guarantee not ammonification or low ammonia in fresh latex;
C. peptizer title and consumption: the white sugar that accounts for dried glue weight 0.6%～0.8% with the sodium alkyl benzene sulfonate 701+ that accounts for dried glue weight 0.1%～0.3%, peptizer all can effectively use during more than or equal to 15 ℃ at temperature, and with temperature raise and in use range relatively decrement use;
D. coagulation mechanism is converted into catalystic, fermentative by spontaneous fermentation.
2, production operation requirement and quality control requirement
2.1 the collection of fresh latex transportation
2.1.1 fresh latex must clean up or lubricated filter screen chute and fresh latex collecting tank before collecting; During collection, with 1/3 wetting filter screen and the collecting tank that used ammonia vol the same day, ammoniacal liquor is made into 5% ammonia soln before use, and the fresh latex ammonia content requires to equal or boy 0.03%.
Directly put into collecting tank 2.1.2 deliver to the no ammoniacal latex of receiving the glue station from plantation after the nominal pore size is 355um or 40 purpose stainless steel sift net filtrations, wash water is collected in addition, is forbidden to sneak into and filters in the fresh latex.
2.1.3 mid-term and later stage that fresh latex is collected are respectively added 1/3 of ammonia volume, require fresh latex to collect and finish, and must fresh latex be transported to glue works at once.
2.2 the mixing of fresh latex, solidify.
2.2.1 from receiving the fresh latex that the glue station is sent here, through weighing, directly put into mixing pit behind centrifugal settling of latex centrifugal filter or the 60 order stainless steel sift net filtrations, fresh latex requires to reach to greatest extent and mixes, after stirring, sampling rapid determination drc and sampling and measuring ammonia of natural latex.Cleaning of evaporator water is collected in addition, does not allow to sneak into the virgin rubber Ruzhong.
2.2.2 latex coagulation adopts auxiliary biological coagulation method, the white sugar consumption is 0.6%～0.8% of a dried glue weight; Sodium alkyl benzene sulfonate 701 consumptions are 0.1%～0.3% of dried glue weight, can solidify operation after auxiliary biological coagulation agent should be dissolved earlier fully.Clotting method adopts channel process down in parallel.
2.2.3 in the latex coagulation process, do not allow in mixing pit, to spray water, when being left last groove latex in the mixing pit, can spraying water in right amount and clean mixing pit periphery and bottom, the grumeleuse of last groove latex, processing separately, its product is handled in addition.
2.2.4 finish solidify operation after, should be in time with mixing pit, spew groove and other apparatus, the place cleans up.
2.2.5 under the normal circumstances, the grumeleuse curing time is 12h～20h.
The invention has the beneficial effects as follows: production technique of the present invention is simple, adopt auxiliary its product tensile strength of biological coagulation method of former latex greater than 22Mpa, satisfy radial glue requirement tensile strength is equal to or greater than 22Mpa greater than 19.6Mpa and aircraft tyre glue requirement tensile strength requirement.
