Abstract
The invention relates to a solution method for producing a butyl rubber inner tire. A production formula comprises, by weight: 100 parts of butyl rubber, 1 part of stearic acid, 5 parts of zinc oxide, 62-78 parts of carbon black, 15-25 parts of naphthenic oil, 3-5 parts of resin, 1-1.5 parts of promoter TMTD, 1 part of rubber sulfuration promoter ZDC and 1-1.5 parts of sulphur. The carbon black comprises 12-18 parts of N550 and 50-60 parts of N660. The method comprises the following steps of: mixing in an internal mixer at 160 DEG C; filtering rubber and vulcanizing: filtering rubber with a rubber filtering temperature no more than 130 DEG C, starting the internal mixer to add sulphur and promoter for mixing, with a rubber temperature controlled below 100 DEG C; carrying out cooking on the rubber treated with mixing with a cooking temperature at 80 DEG C and a die temperature maintained at 115 DEG C; jointing for 4 s by a splicer; and inflating for fixing and vulcanizing at high temperature no less than 170 DEG C for a short time. The butyl rubber product prepared by the solution method is similar to that prepared by a slurry process.
Description
Technical field
The present invention relates to a kind of working method of solution method butyl rubber inner tube.
Background technology
Because solution method butyl rubber product molecular weight distribution broad; There is the branching phenomenon in molecular chain; There are a certain distance in its product performance and complete processing and slurry process; So at present in the world seldom, domesticly it is not carried out the exploratory development in inner tube of a tyre application facet to the application of solution method butyl rubber yet.
Butyl rubber is the multipolymer of iso-butylene and a small amount of isoprene.The constructional feature of butyl rubber is that saturation ratio is high, and degree of unsaturation is extremely low.Its degree of unsaturation is merely 0.5%～3.3% (mol), is about 1/50 of tree elastomer.Therefore; Butyl rubber has a series of good characteristics: resistance to air loss is good, flexibility is good, weathering resistance is good, good chemical stability, and it still in the future all is to keep the only material of doughnut resistance to air loss now that butyl rubber and main verivate halogenated butyl rubber thereof are not only.
At present, the working method of butyl rubber mainly is slurry process and solution method, wherein uses slurry process generally, and this production technology is grasped by Ka Musike company under Exxon Neftegas Limited, German Lanxess Corporation and the Russia.The production technology of solution method butyl rubber is by Russian Tao Liyadi viton company and the cooperative development of Italian Pressindustra company, only Russian in the world now Tao Liyadi viton company production solution method butyl rubber.Because solution method butyl rubber product molecular weight distribution broad; There is the branching phenomenon in molecular chain; There are a certain distance in its product performance and complete processing and slurry process; So at present in the world seldom, domesticly it is not carried out the exploratory development in inner tube of a tyre application facet to the application of solution method butyl rubber yet.
Summary of the invention
The working method that the purpose of this invention is to provide a kind of solution method butyl rubber inner tube under the situation that does not reduce inner tube of a tyre performance, is improved the production technique of the inner tube of a tyre, alleviates the nervous problem of butyl rubber application demand.
The working method of solution method butyl rubber inner tube of the present invention, its production formula is by weight: butyl rubber 100, Triple Pressed Stearic Acid 1, zinc oxide 5; Carbon black 62～78, NO 15～25, resin 3～5; TM monex TD 1～1.5, thiofide ZDC 1, sulphur 1～1.5; Wherein the prescription of carbon black is: N550:12～18, N660:50～60.
(1) calendering process: in Banbury mixer, butyl rubber is plasticated behind the 2min, add Triple Pressed Stearic Acid, zinc oxide successively, add the carbon black that accounts for carbon black total amount 1/2 again, add residue carbon black, NO, resin, binder removal behind the mixing 3min behind the mixing 3min successively; The Banbury mixer temperature: 160 ℃, rotating speed: 40r/min;
(2) filter glue, add sulphur: earlier filter glue after vulcanization sulphur or add sulphur earlier after filter glue; Rubber strainer adopts double-layer leaching net, and the first layer is No. 18 sieve apertures, and the second layer is No. 40 sieve apertures, and dump temperature≤130 ℃ open that Banbury mixer adds sulphur and promotor is mixing, and the glue temperature control is below 100 ℃;
(3) finished product is extruded: will filter glue and add the glue of sulphur after mixing and carry out heat refining, cooking temperature supplies the adhesive tape of glue to want evenly can not interrupt, in order to avoid air is involved at 80 ℃; Shape of the mouth as one speaks temperature should remain on 115 ℃; The speed of conveying belt should be complementary with extruded velocity, and avoids throwing off, otherwise the porous that can cause inboard wall uneven contraction during with cooling; Extrude simultaneously size must be as much as possible size during near the sulfuration typing, to reduce because of the flexible problems such as became uneven that cause of tire tube.
(4) joint technology: the same with calendering process, joint technology also is the important step that the IIR inner tube of a tyre is produced, and the joint defective accounts for the large percentage of whole substandard products.Adopt LJD-Y450 type splicer, through TE, finally confirmed the joint controlled variable: docking time 4s; Joint electric current 5～10A; Joint pressure is as far as possible little; Storage period 10～20min.
(5) sulfuration process: when inflation typing should slowly charge into gas, and 90% o'clock of volume when being inflated to tyre tube vulcanizer, and should be arranged the intermittence of an about 20s, i.e. inflation should be carried out in two steps, and sulfuration should be carried out being not less than in following short period of time of high temperature of 170 ℃.
