Abstract
The invention relates to a method for producing a thin butyl rubber product with reclaimed rubber of butyl capsules, which comprises an open mill, a splicer, a vulcanizer and an internal mixer that are used in the preparation. Raw materials and portions by weight of the thin butyl rubber product are as follows: 100 portions of the reclaimed rubber of butyl capsules, 9 portions of reclaimed rubber of ethylene-propylene diene monomer (EPDM), 3 portions of zinc oxide, 7.7 portions of 4221 reinforcing agent, 7.7 portions of talcum powder, 0.9 portion of DM or M, 1.35 portions of TT and 0.9 portion of sulfur. The product is prepared in the following steps: the reclaimed rubber of butyl capsule, the restored EPDM rubber, the zinc oxide, the 4221 reinforcing agent and the talcum powder are taken according to proportion and put into the internal mixer for mixing at the temperature of 150 DEG C for 7-8 minutes and tabletted and filtered; and the DM or the M, the TT and the sulfur are added into the open mill and placed for 8 hours. The splicer conducts splicing and a valve cock is pressed down, and the tablet is placed for 8-24 hours; and vulcanization is conducted for 8-9 minutes at the temperature of 170 DEG C. The method has the advantages of low price, good plasticity, uniform quality of compounded rubber, labor-hour saving and reduction in power consumption. Furthermore, a sizing material has good fluidity and low thermal plasticity, and the original shape of the sizing material is easily kept when in formation and vulcanization. The product has good appearance and strong elasticity.
Description
Technical field
The present invention relates to a kind of regeneration and working method of waste old, specifically use the method for producing thin butyl rubber product with reclaimed rubber butyl capsule.
Background technology
The regeneration of butyl capsule is as the part of recycling economy, turn waste into wealth, enlarged the source of rubber, saved the butyl virgin rubber, reduce the goods cost, improved the processing performance of sizing material, saved power consumption of polymer processing, and can improve some performances of goods, thereby a series of technology and economical effectiveness have been received.Because curing time length has restricted the application in slim isoprene-isobutylene rubber goods, because the former resin cure of using of butyl capsule will be used sulfur cross-linking earlier after the regeneration, curing time was long, influences production efficiency when but butyl capsule reclaimed rubber was used.
Summary of the invention
The objective of the invention is when using at prior art butyl capsule reclaimed rubber provides a kind of method with producing thin butyl rubber product with reclaimed rubber butyl capsule because curing time length has restricted the deficiency of the application in slim isoprene-isobutylene rubber goods.
Realize the foregoing invention purpose by the following technical solutions: a kind of method with producing thin butyl rubber product with reclaimed rubber butyl capsule, comprise the mill, splicer, vulcanizer, the Banbury mixer that use in the preparation process, the raw material of described slim isoprene-isobutylene rubber goods and weight part are: 100 parts of butyl capsule reclaimed rubbers, 9 parts of Ethylene Propylene Terpolymer reclaimed rubbers, 3 parts in zinc oxide, 7.7 parts of 4221 strengthening agents, 7.7 parts of talcum powder, DM or M0.9 part, TT1.35 part, 0.9 part in sulphur;
By following step preparation
A. mixing filtration adds sulphur
Get 100 parts of butyl capsule reclaimed rubbers, 9 parts of Ethylene Propylene Terpolymer reclaimed rubbers, 3 parts in zinc oxide, 7.7 parts of 4221 strengthening agents, 7.7 parts of talcum powder, it is mixing to put into Banbury mixer, 150 ℃ of melting temperatures, mixing time 7～8 minutes, slice is filtered; In mill, add DM or M0.9 part, TT1.35 part, sulphur was parked 8 hours for 0.9 part;
B. joint
Inflating valve is pressed in the splicer top connection, parks 8-24 hour;
C. sulfuration
Curing time is 8～9 minutes, 170 ℃ of temperature.
Adopt technique scheme,, the cost of goods is reduced because the present invention adopts butyl capsule reclaimed rubber, regeneration ethylene-propylene diene copolymer.Use 4221 strengthening agents, talcum powder has strengthened sizing material processing performance in process of production.The invention has the beneficial effects as follows: 1, low price.Its rubber hydrocarbon content is about 50%, and contains a large amount of valuable resins, tenderizer, zinc oxide and carbon black etc., and its tensile strength at yield can reach more than the 9-10%.2, good plasticity-is arranged, mix quality is even, saves man-hour, reduces power consumption.3, the heat of giving birth to of the courses of processing such as mixing, heat refining, extrusion is reduced, thereby avoid the too high and incipient scorch of Yin Jiaowen.4, rubber mobility is good, so extruder rate is fast, and swelling property is little during extrusion, and work piece macroscopic irregularity is few.5, sizing material thermoplasticity is little, is easy to hold its shape when moulding and sulfuration.6, because of the resin content height, so the strength of joint height.7, the finished product outward appearance is good, and elasticity is strong.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
