Description

The light-type conveyer belt and preparation method thereof of the compound Teflon of polyurethane surface
Technical field
The present invention relates to a kind of light-type conveyer belts and preparation method thereof of the compound Teflon of polyurethane surface, belong to conveyer belt Technical field.
Background technology
Light-type conveyer belt is the fine product in conveyer belt, with cotton, polyamide（PA）, the fabrics such as terylene are as belt carcass or bone Frame material, with rubber（Including rubber and plastic）Or plastics are as coating（It also can intectate band）, surface can be smooth, also may be used To have the depth decorative pattern of various patterns or lateral profile bar, baffle and corrugated sidewall.Light-type conveyer belt is frivolous with band body, size is steady The features such as qualitative good, precision is high, color is lucid and lively, tension is high, safe and non-toxic.Meanwhile with the development of technology of preparing, for user The product category and performance range of selection are more and more wider, can have the various particularity such as antistatic, corrosion-resistant, fire-retardant, low noise Energy.
It, can by the material type of the coating of light-type conveyer belt according to 2009 light-type conveyer belts of standard GB/T/T23677 It is classified as two major classes：Rubber-type（Including rubber-plastic type）And shaped plastics（Including polyvinylchloride, thermoplastic polyurethane elastomer TPU, polythene PE etc.）.Traditional rubber conveyer belt is invented by DuPont Corporation to be produced and is conveyed for various articles, so far Has more than 100 years history.Substantially based on natural rubber, nitrile rubber, neoprene, butadiene-styrene rubber etc..Currently, passing through Plastics enhance the use of the modified raw material such as rubber and Plastics Toughening by Rubber, promote to turn to by the conveyer belt of primary raw material of rubber Novel rubber plastic composite material conveyer belt.
The development of polymer modification technology plays great impetus to the development of new material used for conveyer belt, leads to The modification to high molecular material is crossed, high intensity, high cohesiveness, high friction are can get and is had fire-retardant, antistatic, environmentally friendly etc. more The Novel conveyer belt material of kind additional properties.
Conveyer belt is generally used for transport bulk material, just needs the conveying with special nature for special operating mode occasion It brings completion to convey, such as just needs a kind of high temperature resistant, oil resistant, anti-sticking conveyer belt to complete to biscuit, sugar in food processing The conveying of fruit, cake.
Invention content
The purpose of the present invention is overcoming above-mentioned shortcoming, a kind of light-duty conveying of the compound Teflon of polyurethane surface is provided Band and preparation method thereof, preparation process environmental protection, product can achieve the purpose that high temperature resistant, prevent adhesion.
Technical scheme of the present invention, the light-type conveyer belt of the compound Teflon of polyurethane surface include spy successively from top to bottom Fluorine dragon film layer, polyurethane gelatinous layer, bottom fabric layer layer and polyester textile skeleton；
The polyurethane gelatinous layer described by weight includes 7-9 parts of 90-110 parts of TPU powder and stabilizer；
The bottom fabric layer layer includes 4-6 parts of 90-110 parts of PU glue, 2-4 parts of lubricant and network cross-linked agent.
The polyester textile skeleton is woven using polyester fiber, is woven especially by warp and weft.Polyester Fiber has higher intensity and elastic recovery capability its biggest advantage is that wrinkle resistance and conformality are fine.Polyester fiber is compiled It knits and to form polyester textile skeleton the tensile strength of conveyer belt is improved.
The warp includes the first warp and the second warp, and first warp is constituted using single polyester fiber, described Second warp is constituted using plurality of fibers, and first warp and the second warp interval are arranged.By using above-mentioned technical proposal, It can form prominent structure to the second warp that plurality of fibers is constituted, to form reinforcing rib, so that entire conveyer belt Tensile strength is improved.
The stabilizer is specially calcium zinc stabilizer.Calcium zinc stabilizer is by based on calcium salt, zinc salt, lubricant, antioxidant etc. Component is wanted to be synthesized using special combination process.It can not only replace the toxic stabilizer such as lead cadmium salt class and organic tin, and And there is fairly good thermal stability, photostability and the transparency and tinting strength, tinting power.It was verified that in PVC resins, add Work performance is good, and heat stabilization is equivalent to lead salt stabilizer, is a kind of good non-toxic stabilizer.The present invention uses XY104 Type calcium zinc stabilizer, the product asepsis environment-protecting, no harmful heavy metal, alternative lead salt, organic tin stabilizer are conducive to environment Protection；With excellent thermal stability, initial coloring is outstanding, and long-time stability and weatherability are excellent；Have both toughening and promotion Melting is plasticized good fluidity, no precipitation；With unique coupled action, the good dispersibility of filler is assigned, promote and is set The package of fat improves the colour brightness and firmness of product, improves products appearance, improves product properties.
The lubricant is specially polyethylene wax or low-molecular-weight polypropylene.The polymer of low molecular weight is also widely used as Lubricant, inside and outside lubricity is all preferable, and nontoxic.Polyethylene wax is suitable for the materials extrusion moldings such as TPU, calendering processing, dosage one As be 0.1 ~ 1phr, processing efficiency can be improved, prevent film blocking, improve the dispersibility of filler or pigment, compatibility and transparent Property is not fine；Irregular structure low-molecular-weight polypropylene can be used as the lubricant of TPU, and function admirable can improve other auxiliary agents Dispersibility.
The network cross-linked agent is specially crosslinking agent TAC.Crosslinking agent is also referred to as bridging agent, is poly- hydro carbons photoresist Important component, the photochemical solidification effect of this photoresist, dependent on the crosslinking agent with double photonasty functional groups Reaction is participated in, generates diradical after crosslinking agent exposure, it and poly- hydrocarbon resins phase separation are formed between polymer molecular chain Bridged bond becomes the insoluble substance of three-dimensional structure.The present invention is using stablizing the country chemical industry crosslinking agent --- and JN852 is by Cyanuric Chloride, and third Enol is combined into reaction crosslinking agent TAC obtained.Its physicochemical property is：Solidification point is 26 DEG C, proportion 1.113, and refractive index is N26D3：1.504, when 30 DEG C of viscosity is 12.55 × 10-3Pa.s, can be with acetone, benzene, chloroform, dioxanes, ethyl acetate, ethyl alcohol It dissolves each other.Solubility is 0.6g/100g water under water, is stablized in alkalinity, meets sour facile hydrolysis, can accelerate to gather with molybdenum, nickel, manganese and mercury It closes, is used as the crosslinking agent and sensitizer of all kinds of rubber and plastics.
Chemical name：Triallylcyanurate, molecular formula：C12H12N3O3, relative molecular weight：249.27 can be significantly Shorten vulcanization time, improve mechanical performance, improves wearability, weatherability and solvent resistance；Heat resistance and machinery can be significantly improved Intensity, heat resistance can be improved to 200 DEG C or more.
The Teflon film is also referred to as polytetrafluoroethylene film, is by suspension polytetrafluoroethylene resin through being molded, burning It ties, be cooled to blank, then through made of calendering.
The preparation method of the light-type conveyer belt of the compound Teflon of polyurethane surface, steps are as follows by weight：
