Description
Technical field
The present invention relates to rubber technical field, more particularly to a kind of chlorinated scoline heat resistance conveyor belt covering
Glue.
Background technology
High-heat-resistant conveyer belt is to be covered with heat-resistant fireproof above and below multilayer rubber duck (polyester-mixed cotton cloth) or polyester canvas
Rubber, be bonded together through high temperature vulcanized.High-temperature-resistant flame retardant conveyor belt is widely used in the high temperature such as metallurgy, coking, building materials work
In industry environment, the high-temp solid material such as main conveying less than 175 DEG C hot cokes, cement, slag, hot-cast part, sintered ores.Due to
Cooling is insufficient, and temperature of charge moment is up to 400 DEG C -- and 600 DEG C, it is ensured that normal operation is transported, these high-temperature materials can not draw
Play conveyer belt burning.Therefore conveyer belt must have good heat-resisting quantity and excellent anti-flammability.
According to elastomeric material characteristic, the heat-resisting good rubber of high temperature resistant has EP rubbers and organic silicon rubber, but both are fire-retardant
Effect is poor；Neoprene good flame retardation effect, but high temperature resistant is restricted, it is impossible to more than 120 DEG C.Chlorinated scoline has in itself
Anti-flammability, high-temperature resistant result is also good, for a long time because price is somewhat expensive, on the conveyor belt using few.
Number of patent application is 201310580244.7 patent of invention, the limited public affairs of the American-European sub- rubber industry in its applicant Qingdao
Department discloses a kind of chlorinated scoline formula, and it disclose only its formula rate, not more explanations.
As the industries such as metallurgy, coking require more and more higher to heat resistance conveyor belt quality and durability of product, selection is suitable
Elastomeric material, meet high temperature resistant and flame-retardancy requirements, this turn into adhesive tape industry in be badly in need of solve and still fail what is effectively solved
One technical problem.
The content of the invention
In view of the technical drawbacks of the prior art, it is an object of the present invention to provide one kind can improve resistance to heated conveying
Chlorinated scoline heat resistance conveyor belt rubber cover with service life.
To realize that the technical scheme that the purpose of the present invention is used is：Chlorinated scoline heat resistance conveyor belt rubber cover, its
It is characterised by, component and mass fraction are as follows：
The present invention component proportion principle be：
(1) elastomeric material of the invention is that chlorinated scoline (CIIR) and ethylene propylene diene rubber (EPDM) are used in combination, CIIR
There are preferable compatibility and intervulcanizability with EPDM, both can be used in combination in any proportion, its physical and mechanical properties is in additive property；Through
Overtesting proves, a small amount of EPDM is added in CIIRK can change CIIR processing characteristicies, improves the pressure-resistant compression deformations of CIIR, resistance to old
Change, abrasion performance and dynamic property；Because CIIR degradation with agings soften, EPDM agings crosslinking is hardened, therefore and can be improved with EPDM
CIIR anti-reversion behaviours, improve CIIR heat resisting temperatures；
(2) chlorinated scoline (CIIR) used in raw material itself has certain anti-flammability, when former based on CIIR
Appropriate chlorinated paraffin is added during material, in formula as fire retardant, the flame retardant effect of blend compounds material is substantially increased；
(3) resin curative systems form stable-C-C- and-C-O-C- cross-bonds in sulfidation, except thermal decomposition
Outside, recovery phenomenon is nearly free from, so with excellent heat resisting performance；But, resin curative systems vulcanization
Speed is slow, low production efficiency, and the fast heat-resisting effect of sulfur-donor curingprocess rate is general.The present invention is using curing resin SP1055-
Zinc methacrylate-alkyl phenol disulfide RPS710 Co-crosslinked Systems, can make to be handed over altogether between CIIR and EPDM
Connection, accelerates curingprocess rate, two kinds of polymer and with co-crosslinking has been reached, both performances obtain complementation, the physics of blend compounds
Mechanical performance is in additive property, so as to improve CIIR and EPDM blend compounds material high temperature resistant heat resistance；
(4) because conveyer belt requirement has higher tensile strength and good abrasion resistance, it just can guarantee that product exists
Used for a long time in hot environment；CIIR and EPDM blend compounds material in the present invention, add super abrasion furnace black N220 and high abrasion
Furnace black N330 as and reinforcing agent improve the tear resistance and abrasion resistance of sizing material.Super abrasion furnace black N220 and height
Abrasion furnace blacks N330 particle size carbon black is smaller than ordinary carbon black, and specific surface area is big, can guarantee that tensile strength in more than 15MPa, simultaneously
Possesses preferable wearability.
The beneficial effects of the present invention are：Chlorinated scoline heat resistance conveyor belt rubber cover of the present invention with CIIR and EPDM simultaneously
With for sizing material, using co-crosslinking vulcanizing system, optimal performance can be obtained after 160 DEG C × 30min compression moldings, is met resistance to
Hot conveyer belt is to heat-resisting, wear-resisting and fire-retardant requirements：Hardness is in the range of 60 ± 5 Shao A, and tensile strength is more than 15.0MPa,
Elongation at break is more than 400%；After 175 DEG C × 96h thermal aging tests, hardness is less than 85 Shao A, and tensile strength is more than 5MPa,
Elongation at break is more than 180%；In terms of anti-wear performance, Akron abrasion is less than 200mm3；In terms of anti-flammability, chlorinated scoline
Heat resistance conveyor belt rubber cover has flame and the nonflame self-extinguishment in 3S in 800 DEG C × 30S combustion tests.
