Description
Technical field
The present invention relates to a kind of infantees V to be with and preparation method thereof, belong to mechanical transmission and field of material technology.
Background technology
Infantees V band is a kind of travelling belt being widely used in various machinery, primarily of industrial canvas, soft polyester cotton rope and primer layer composition, described primer layer is primarily of natural rubber, styrene-butadiene rubber(SBR), reclaimed rubber and Synergist S-421 95 (zinc oxide, stearic acid, anti-aging agent, carbon black, tenderizer etc.).But existing infantees V is with ubiquity product easily to cave in, cause distortion large, and the problem such as antifatigue flexural property is poor, easily breaks down, and work-ing life is short.Existing infantees V band also has longitudinal in V band (being equivalent to the length direction that infantees V is with) to be wound with soft polyester cotton rope to the longitudinal tensile strength performance providing infantees V to be with.But if adopt polyester rigid line rope in infantees V is with after, easily there is depressed phenomenon in infantees V band, and makes infantees V be with transverse deformation, causes infantees V to be with friction between side and belt wheel to increase, make infantees V be with fragile.As Chinese patent (Authorization Notice No.: 101204852B, the day for announcing: on 04 21st, 2010) manufacture method of disclosed a kind of trimming tooth type rubber V belt, it specifically discloses this tooth type rubber V belt and comprises primer layer, adhesive-layer, polyester rigid line rope and the cushion gum layer be made up of fiber film, and covers at the upper surface of cushion gum layer and be stained with top cloth.Also specifically disclose the concrete weight proportion of the fiber film for primer layer:
Chloroprene rubber: 80 ~ 100; Carbon black: 45 ~ 75; Styrene-butadiene rubber(SBR): 0 ~ 20; Magnesium oxide: 3.5 ~ 7.0; Zinc oxide: 3.5 ~ 5; Promotor: NA-22:0.2 ~ 0.5; Stearic acid: 1 ~ 1.5; Short polyester fiber: 15 ~ 25; Anti-aging agent LE-W:1.5 ~ 2.0; Tenderizer: 5 ~ 10.It is specifically designed to preparation to have tooth edge V tape, has rational technology, the technique effect that cost is low.But, if be directly applied to infantees V band also there is many defects, it is unreasonable that the one-tenth of fiber film is grouped into compatibility, directly apply to infantees V to be with, because strength layer adopts polyester rigid line rope, material is harder, depressed phenomenon can be there is by product in use procedure, in addition, although, fiber film is added with short polyester fiber, but, because fiber film is formed by calendering in the course of processing, thus cause the short polyester fiber in fiber film to present the mode of longitudinal arrangement, the polyester rigid line rope direction be longitudinally wound around during direct use can make the orientation of short polyester fiber be with V is consistent, thus do not have supporting role, also product can be made easily to occur depressed phenomenon, transverse deformation is serious, reduce the work-ing life of product.
Summary of the invention
The present invention is directed to above problems of the prior art, a kind of new infantees V is provided to be with and preparation method thereof, can realize product not easily cave in and produce the rational technique effect of composition proportion in distortion, fiber film, and described method has technique simply, the technique effect that cost is low.
An object of the present invention is achieved by the following technical programs, a kind of infantees V band, described infantees V band comprises sandwich layer and is coated on the infantees layer of sandwich layer outside surface, described sandwich layer is comprised primer layer, adhesive-layer, polyester rigid line rope and the cushion gum layer be made up of fiber film successively by bottom to top, described fiber film comprises the weight part of following composition:
