Description of drawings
Fig. 1 is the technological process of production figure of impact resistance high wearing-proof conveyer belt of the present invention.
Fig. 2 is the structure cross-sectional schematic of load-transfer device of the present invention.
The specific embodiment
The present invention will be helped to understand by following embodiment, but content of the present invention and protection domain can not be limited.
Embodiment one: the structure of load-transfer device of the present invention is made up of last rubber cover 1, cushion compound 2, belt carcass 3, following rubber cover 4 and limit glue 5 as shown in Figure 2.Reach the double effects of shock resistance and high abrasion, the making of rubber cover is crucial.The rubber cover of present embodiment prepares material and comprises following component and weight content: 70 parts of natural gums, and 30 parts of rubber polymers, 1.8 parts in sulphur, 5 parts in zinc oxide, 2.5 parts of stearic acid, 1.8 parts of accelerators, 55 parts of reinforcing agents, soften flux 11.5,3 parts in aging inhibitor adds up to 180.6 parts.
The elastomeric material aspect, natural gum elasticity, brute force, adhesive bonding property, shop characteristic are all fine, but wear hardness is slightly poor, and impact elasticity is less than cis-butadiene cement.The cis-butadiene cement resistance to abrasion is fine, and elasticity is also good than butadiene-styrene rubber, natural gum, be as the reasonable glue kind of impact resistance high wearing-proof conveyer belt rubber cover, but its brute force is low, and viscosity is poor, and shop characteristic is bad, can only and use with natural gum.Butadiene-styrene rubber is general rubber polymer, and powerful better than cis-butadiene cement, wear hardness is better than natural gum, but elastic ratio cis-butadiene cement and natural gum are poor.More than in three kinds of rubber production based on natural gum, the part of suitably arranging in pairs or groups cis-butadiene cement or butadiene-styrene rubber.
In order to satisfy the performance requriements of impact-resistant and high-wear-resistant, need below be to describe in detail to reinforcing agent, soften flux, vulcanizing system and aging inhibitor research experiment in the prescription and preferred:
The reinforcing agent aspect is because that the brute force of the rubber cover of impact resistance high wearing-proof conveyer belt requires is high, so select for use us to do many tests to reinforcing agent.From test results, the performance of Maoming intermediate super abrasion furnace black (N220) is good, and this carbon black physical property after chemically examining is: tensile strength at break 25.9Mpa, elongation at failure 475%, DBP absorption value 115 * 10
-5m
3/ Kg.Resistance to abrasion was good after prescription added N220, and pulling strengrth is also big, and resistance to abrasion exceeds 10-20% with respect to high wear-resistant carbon black (N330), and hardness has then increased 2-3A (Shao Er).Maoming high abrasion (N330) is also good to the reinforcing property and the wear hardness of sizing material, and physical property is after chemically examining: tensile strength at break 25Mpa, elongation at failure 450%, DBP absorption value 110 * 10
-5m
3/ Kg.Two kinds of N220 and N330 and time spent, N220 uses 15-20 part generally speaking, and N330 uses 35-40 part, and two kinds add up to 55 parts.And this prescription chemical examination back physical property tensile strength at break is 19-21Mpa, and abrasion are at 40-80mm
3Between.
Reinforcing agent is made owing to add more carbon black in the prescription in the soften flux aspect, just can make sizing material in refining glue and rolling out film technology the favorable manufacturability energy be arranged so must add certain soften flux.Soften flux commonly used has solid coumarone resin, pitch, machine oil and pine tar, and these several soften fluxs to the influence of tensile strength, elongation at failure, elasticity and the abrasion of prescription are:
Tensile strength: solid coumarone＞pitch＞machine oil＞pine tar
Elongation at failure: pine tar＞machine oil＞pitch＞solid coumarone
Elasticity: pine tar＞machine oil＞pitch＞solid coumarone
Wear hardness: pitch＜solid coumarone＜machine oil＜pine tar
Consider from physical property and shop characteristic, preferably select solid coumarone and machine oil and usefulness for use.Because gum content is higher in the prescription, if add pine tar then sizing material viscosity is excessive, the molding procedure inconvenient operation, though and pitch wear resistance ratio coumarone is better, reinforcing property is less than coumarone.
The vulcanizing system aspect adopts sulfur cross-linking owing to added partly rubber polymer, sulfur consumption during greater than 2 parts hardness want height a bit, aged properties is also a little bit poorer, thus sulfur consumption be 1.8 parts proper.
General aging inhibitor commonly used can be used in the aging inhibitor aspect, can reach aging requirement about 3 parts, and about elongation at failure-5%, percentage elongation is about-10～15% after 70 ℃ * 168h rubber cover is aging.
The following two kinds of canvas of optional usefulness are as the framework material of impact-resistant and high-wear-resistant: a kind of is the nylon dipped canvas, nylon fiber claims nylon fibre again, be that present adhesive tape uses maximum framework materials, nylon fibre is a kind of fiber powerful higher in the syntheticfibres of suitability for industrialized production, its hydroscopicity is very low, the elasticity height, fatigue durability is good, the rebound degree of nylon fibre is 98-100%, nylon cloth and rubber adhesion power through impregnation are higher, the adhesive tape that company produces, generally (standard 〉=4.5N) is so can stand HI high impact at 7-9N/mm for the nylon cloth interlayer adhesion, high-speed cruising is difficult for absciss layer, be difficult for coming unstuck, because adhesive tape is made up of the multilayer canvas.Cloth and cloth, layer of cloth and glue-line are bonding good, are difficult for absciss layer and destruction when being hit power.Another kind is the EP canvas, claims the polyester/nylon canvas again, and its warp-wise is a poly-ester fibres, and broadwise is a nylon fiber, its powerful high, good heat resistance, warp-stretch is little, and the adhesive tape made from it extends little in operational process, dimensionally stable, but its hardness is big, deflects performance less than nylon canvas.
With reference to flow scheme shown in Figure 1, the production technology of impact resistance high wearing-proof conveyer belt of the present invention is described as follows:
1) rubber mixing technique: rubber cover can carry out in mill, also can carry out in Banbury mixer.But Banbury mixer is effective, and sizing material is uniformly dispersed, error is little.But just can carry out mixing after cis-butadiene cement must refine evenly with natural gummed, if do not close refining evenly carry out mixing because cis-butadiene cement is stronger than natural gum to the affinity of carbon black, the carbon black that cis-butadiene cement is sneaked into will prior to greater than natural gum, thereby causing the irregularity of sizing material, the brute force of sizing material is also low.We have done test at rubber mixing technique: cis-butadiene cement and natural gum close evenly back rubber Hui Leng of refining earlier, and second day mixing again sizing material do not close refining and the mixing powerful big 2-3Mpa of sizing material than two kinds of glue.From the section of vulcanizate, the latter can see grain, this glue again with mill repeatedly thin-pass also be difficult for being uniformly dispersed.
2) calendering technology: the sandwich layer of impact resistance high wearing-proof conveyer belt adopts the NN canvas or the EP canvas of duck conveyor belt.Its rubber cover rolling out film and normal tape difference are little, because its rubber gum content height, semi-manufactured goods quality requires high, want strict so go out blade technolgy, the thick refining and the refining of sizing material carried out in technological operation, and the film size that guarantee to extrude is accurate, smooth surface, do not have cold line, no bubble.
3) forming process: the viscosity of rubber cover is good, film is powerful big, the relatively good operation of molding procedure, but under the environment of weather sweltering heat, if sizing material viscosity is excessive, operate also pretty troublesome, the chill roll of major control rolling out film machine at this moment, temperature will be hanged down, and film operation after fully cooling off does not just have too big inconvenience.Perhaps standing time is longer after the slice.
4) sulfuration process: little with the normal tape difference, but because gum content height, sizing material is more sticking, thus the time of the sprinkling of the water-soluble silicon oil before will noting vulcanizing and and concentration, before sulfuration, sprayed in 1 to 2 minute, behind the adhesive tape sulfuration matched moulds 1 to 2 minute the time pine press two to three times, at this moment silicone oil is vaporized after heating, and the air of tape surface can be discharged smoothly when pine is pressed, and the product mold filling performance of sulfuration is good, smooth surface, outward appearance is good.
