Abstract
The invention discloses a chlorinated butyl rubber heat-resistant conveyer belt cover rubber which is composed of chlorinated butyl rubber, ethylene propylene diene monomer rubber, medium super abrasion furnace black, high-wear-resistance carbon black, chlorinated paraffin, paraffin oil, zinc methacrylate, light magnesium oxide, dibenzothiazyl disulfide, alkyl phenol disulfide, a vulcanized resin, a tackifying resin, stearic acid, PE (polyethylene) wax, N-isopropyl-N'-phenyl p-phenylenediamine and a 2,2,4-trimethyl-1,2-dihydroquinoline polymer. The chlorinated butyl rubber heat-resistant conveyer belt cover rubber has the advantages of flame-retardant effect, high-temperature/heat resistance, higher tensile strength and favorable attrition resistance.
Description
Technical field
The present invention relates to rubber item technical field, particularly relate to a kind of chlorinated butyl rubber heat resistance conveyor belt rubber cover.
Background technology
High-heat-resistant conveyer belt be by multilayer rubber cotton duck (polyester-mixed cotton cloth) or polyester canvas be covered with up and down heat-resistant fireproof rubber, be bonded together through high temperature vulcanized.High-temperature-resistant flame retardant conveyor belt is widely used in the high temperature operating environments such as metallurgy, coking, building materials, the high-temp solid materials such as main conveying less than 175 DEG C hot cokes, cement, slag, hot-cast part, sintered ores.Insufficient owing to cooling, temperature of charge moment can reach 400 DEG C--and 600 DEG C, ensure that normal operation is transported, these high-temperature materials can not cause conveying belt to burn.Therefore conveying belt must have good high thermal resistance and excellent flame retardant resistance.
According to elastomeric material characteristic, high temperature resistant heat-resisting good rubber has ethylene-propylene rubber(EPR) and organo-silicone rubber, but both flame retardant effects are poor; Chloroprene rubber good flame retardation effect, but to be high temperature resistantly restricted, can not more than 120 DEG C.Chlorinated butyl rubber itself has flame retardant resistance, and high-temperature resistant result is also good, and for a long time because price comparison is expensive, application is few on the conveyor belt.
Number of patent application is the patent of invention of 201310580244.7, and the American-European sub-rubber industry company limited in its applicant Qingdao discloses a kind of chlorinated butyl rubber formula, and it disclose only its formula rate, does not more speak more bright.
Along with the industries such as metallurgy, coking require more and more higher to heat resistance conveyor belt quality and durability of product, select suitable elastomeric material, meet high temperature resistant and flame-retardancy requirements, this has become in adhesive tape industry is badly in need of solving and still fails the technical problem that efficient solution determines.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of chlorinated butyl rubber heat resistance conveyor belt rubber cover that can improve heat resistance conveyor belt work-ing life is provided.
The technical scheme adopted for realizing object of the present invention is: chlorinated butyl rubber heat resistance conveyor belt rubber cover, is characterized in that, component and mass fraction as follows:
Component proportion principle of the present invention is:
(1) elastomeric material of the present invention is chlorinated butyl rubber (CIIR) and terpolymer EP rubber (EPDM) and uses, CIIR and EPDM has good consistency and inter-vulcanizability, both can with any ratio and use, and its physical and mechanical properties is additivity; Prove through overtesting, add a small amount of EPDM in CIIRK and can change CIIR processing characteristics, improve the distortion of CIIR compression, ageing-resistant, abrasion performance and dynamic property; Due to the deliquescing of CIIR degradation with aging, EPDM is aging crosslinked hardening, therefore also can improve CIIR anti-reversion behaviour with EPDM, improves CIIR heat resisting temperature;
(2) chlorinated butyl rubber (CIIR) used in raw material itself has certain flame retardant resistance, when taking CIIR as main raw material, adding appropriate clorafin again as fire retardant, substantially increase the flame retardant effect of blend compounds material in formula;
(3) resin curative systems forms stable-C-C-and-C-O-C-cross-link bond in sulfidation, except thermolysis, produces reversion phenomenon hardly, so have excellent heat resisting performance; But resin curative systems vulcanization rate is slow, and production efficiency is low, the fast heat-resisting effect of sulfur-donor vulcanization rate is general.The present invention adopts curing resin SP1055-zinc methacrylate-alkyl phenol disulfide RPS710 Co-crosslinked System, can make to carry out co-crosslinking between CIIR and EPDM, accelerate vulcanization rate, two kinds of polymkeric substance with reaching co-crosslinking, both performances obtain complementation, the physical and mechanical properties of blend compounds is additivity, thus improves the high temperature resistant resistance toheat of CIIR and EPDM blend compounds material;
(4) because conveying belt requires to have higher tensile strength and good abrasion resistance, guarantee product uses for a long time in hot environment; CIIR and EPDM blend compounds material in the present invention, adds super abrasion furnace black N220 and high abrasion furnace black(HAF) N330 as strengthening agent also to improve tear resistance and the abrasion resistance of sizing material.Super abrasion furnace black N220 is less than ordinary carbon black with the particle size carbon black of high abrasion furnace black(HAF) N330, and specific surface area is large, can ensure that tensile strength is at more than 15MPa, possesses good wear resistance simultaneously.
Beneficial effect of the present invention is: chlorinated butyl rubber heat resistance conveyor belt rubber cover of the present invention is with CIIR and EPDM and with being sizing material, adopt co-crosslinking vulcanization system, best performance can be obtained after 160 DEG C × 30min compression molding, meet heat resistance conveyor belt to heat-resisting, wear-resisting and fire-retardant requirements: hardness is within the scope of 60 ± 5 Shao A, tensile strength is greater than 15.0MPa, and tensile yield is greater than 400%; After 175 DEG C × 96h heat ageing test, hardness is less than 85 Shao A, and tensile strength is greater than 5MPa, and tensile yield is greater than 180%; Wear resisting property aspect, Akron abrasion is less than 200mm
3; Flame retardant resistance aspect, chlorinated butyl rubber heat resistance conveyor belt rubber cover, in 800 DEG C × 30S combustion test, has flame and nonflame all certainly to put out in 3S.
