Abstract
The invention relates to a finger-shaped connector of an aramid fiber conveying belt and a preparation method of the finger-shaped connector. The preparation method comprises the following steps: stripping coverage glue, cleaning residual glue, cutting finger shapes, coating mucilage, splicing the finger shapes, forming and coating glue, reinforcing by a fabric layer, covering glue, and sulfurizing a specimen, thereby obtaining the finger-shaped connector on the aramid fiber conveying belt. According to the invention, the problems of extraction, edge wrapping, water seepage, glue failure of seams and the like of the connector of the conveying belt in the dynamic running process are solved; a certain gap is reserved in splicing the finger shapes so as to guarantee that the pasting glue can seep fully toward the finger shapes, the extraction force is increased, the stress uniformity is improved, and the phenomena of extraction and cracking which are caused by stress uniformity are prevented; the length of the stripped coverage glue is greater than the length of each finger by 5cm, and the connector glue and the coverage glue are lapped into an oblique slope, so that the phenomenon of water seepage of a framework material because of glue failure of the seam is prevented, and the service life of the connector of the aramid fiber conveying belt is prolonged greatly.
Description
Technical field
The present invention relates to a kind of aramid fiber conveying belt and refer to type joint and preparation method thereof, the aramid fiber conveying belt that is specifically related to the straight latitude programming structure of a kind of framework material filament strength diameter high, thin thickness refers to type joint and preparation method thereof, belongs to rubber conveyer belt goods field.
Background technology
The research work of China's aramid fiber conveying belt is started late, and is mainly that the production technology of aramid fiber rests in the minority west transnational enterprise hands such as Du Pont, Supreme Being people, expensive.Along with the progress of domestic science and technology and the raising of industrial level, domestic existing Ji Jia enterprise can carry out the production of aramid fiber, but small, as Yantai spandex, Henan god horse etc.Aramid fiber prices, the increase in demand of market to high-performance conveyer belt in recent years, makes the batch application of aramid fiber in conveyer belt become possibility, has at present Duo Jia conveyer belt enterprise and aramid fiber conveying belt is carried out to positive development.
In industrial experiment process, joint problem is maximum technological difficulties that expose.Aramid fiber canvas thin thickness, while referring to type fork-join, contact area is little, must refer to the long strength of joint that increases by prolongation.Aramid fiber conveying belt more than 2500S, refers to longly generally more than 3m, and need to splice 3 above sulfuration flat boards can vulcanize, and joint quality is difficult to guarantee.Joint is prone to extraction, alice, infiltration, the seam various problems such as come unglued in dynamic running process, has had a strong impact on the service life of aramid fiber conveying belt.
Application number is that 201310027979.7 patent of invention discloses a kind of diameter conveyer belt and refers to type joint and preparation method thereof, preparation method by this invention has improved strength of joint, and other position thickness of joint area and diameter conveyer belt are equated, joint is stressed evenly, soft, anti-fatigue performance is good, yet, diameter conveyer belt by this invention preparation refers to that type joint still can not meet the needs in market, as the problem due to the cutting of finger type, easily cause occurring in use procedure the problem of alice, extraction.
Summary of the invention
The object of the invention is to improve the joint life-span of aramid fiber conveying belt, especially for occurring the problem of alice, extraction in conveyer belt use procedure.
Technical scheme of the present invention is as follows:
Aramid fiber conveying belt refers to a preparation method for type joint, comprises the following steps:
Peeling off of 1 rubber cover
Peel off the upper and lower rubber cover of aramid fiber conveying belt joint area; Preferably, the cut place of rubber cover is the slope of 45 degree, and is polished in slope.
The cleaning of 2 residual gum
Remove the remaining glue on framework material surface, the rubber polishing around of framework material surface, groove is crude, and cleaning is clean, removes trickle particle, and skeleton surface is dried.
The cutting of 3 finger types
By the joint area justify align of aramid fiber conveying belt, at conveyer belt, longitudinally draw perpendicular bisector in surface, with marking pen, to perpendicular bisector both sides, every Yi Ge finger beam unit, identify, along the line of finishing, cut, during cutting, follow and stay few principle more, to facilitate carrying out of splicing operation, redundance is removed; The limit portion finger beam of described finger type joint area be more than or equal to finger beam half add the width of 1cm, the center line of take when measuring and calculating finger beam distributes distributes to both sides as benchmark, when half that is less than finger beam when outermost finger beam adds the width of 1cm, increase outermost finger beam, the amount of increase deducts on adjacent finger beam.
4 brushing rubber cements
With 120# gasoline, clean joint surface, can brushing rubber cement after gasoline dries, be generally coated with rubber cement twice, be coated with rubber cement and want thin and even, do not leak whitely, non-foaming, last tack-free again slightly when viscosity sense all over glued membrane, then be coated with glue second time; Wherein, rubber cement is that high adhint sizing material is fully dissolved in 120# gasoline, and cord rubber belt and 120# quality of gasoline ratio are 1:4.5-5, and preferred, cord rubber belt and 120# quality of gasoline ratio are 1:4.5.
For the available iodine tungsten lamp hair-dryer of increasing work efficiency, to accelerate the volatilization of solvent in glue.
5 splicings refer to type
The joint area of making is alignd along perpendicular bisector, intersect and dock, the space of the reserved 2mm left and right, place, gap of intersection, fills place, the gap use adhesive tape of docking; Wherein, adhesive tape is to be made in flakes by high adhint sizing material calendering, and thickness is 0.5mm-1mm, and suitable length and the width of cutting used as required.
6 moulding rubberizings, fabric enhancement Layer, rubber cover
Use the adhesive tape that 1-2mm is thick to cover joint upper and lower surface, after compacting, spread fabric enhancement Layer, fabric enhancement Layer and belt parallel longitudinal, the last upper and lower rubber cover of moulding, wherein fabric enhancement Layer is high-tenacity polyester eyelet fabric.
7 sample sulfurations
With the above and below of silicone oil paper protection joint area, the sample of forming is put into the sulfuration of vulcanizer Pressurized-heated; Wherein, the process conditions of sulfuration are: the belt body surface pressing 2.0Mpa of conveyer belt, curing temperature is 140-147 ℃, and cure time is 20-40min, and the compression factor before and after conveyer belt belt body is 1:0.85-0.9, when the time stops, stop heating, allow it naturally cool to 70 ℃ of pressure releasing die sinkings again when following, obtain, preferably, the compression factor before and after conveyer belt belt body is 1:0.9.
Further, the outside of limit portion finger beam should crop 0.5-1cm, and it is excessive to carry out fillet; Preferably, reduce 1cm, and it is excessive to carry out fillet.
Further, the Length Ratio of peelling off rubber cover in the present invention refers to long many 5cm.
The finger type joint obtaining by preparation method of the present invention also belongs to protection scope of the present invention.In addition,, during for the operation of the aramid fiber conveying belt of finger type joint of the present invention, limit portion finger tip points to contrary with traffic direction.
The straight knitting device structure of diameter: main warp line linearly, straight arrangement, parallel linearly, be positioned at the upper and lower surface of main warp line and arranged vertically with main warp line, connect that warp is contained between main warp line, the upper and lower crooked parallel that is wound around, by main warp line and parallel integrated by weaving.
