The high-performance total chloroprene rubber adhesive wide-angle fabric V-belt consists of a wrapping cloth layer, an extension layer, a strong layer and a compressed layer, wherein the compressed layer (namely, primer) is prepared from the following raw materials in parts by weight: 100 parts of chloroprene rubber, 10-20 parts of short-staple, 8-15 parts of organic modified nano montmorillonite, 0.4-0.6 part of stearic acid, 2-4 parts of anti-aging agent, 5-8 parts of zinc oxide, 4-6 parts of magnesium oxide and 2-5 parts of softening agent; the short-staple is one or more of aramid short fiber, nylon short-staple and polypropylene staple fiber. In a primer material of the high-performance total chloroprene rubber adhesive wide-angle fabric V-belt, the chloroprene rubber raw material is modified by the short-staple and the organic modified nano montmorillonite in a composite way, so that high strength, superior deflection resistance and superior fatigue resistance are achieved.
Description
Technical field
The present invention relates to transmission belt technical field, particularly a kind of high-performance full neoprene latex Wide-angle cloth V is with.
Background technology
The parts formations such as layer, strength layer and compressive layer, also known as V-type band, primarily of infantees layer, are upheld in wire belt, are a kind of rubber items being widely used in machinery and equipment dynamic transmission.Compressive layer glue, also known as primer, occupies very large component in wire belt.V be with in use procedure require primer to have heat-resisting, ageing-resistant, flex fatig resistance, compression set are little, lateral stiffness and the advantage such as longitudinal flexible is good.
Usually adopt a certain proportion of nano carbon black to fill enhancing V at present and be with primer, but carbon black take oil as raw material, energy consumption is large and expensive, can not improve the longitudinal flexible of primer and warping strength fatigue property simultaneously, is therefore with primer material in the urgent need to developing a kind of new V.
Summary of the invention
In order to solve existing chloroprene rubber V band Problems existing, the invention provides a kind of high-performance full neoprene latex Wide-angle cloth V to be with, adopt staple fibre and organic modified nano montmorillonite Composite modified chloroprene rubber raw material, there is higher intensity and excellent warping strength fatigue property.
The technical scheme that technical solution problem of the present invention adopts is:
A kind of high-performance full neoprene latex Wide-angle cloth V band, by infantees layer, uphold layer, strength layer and compressive layer four part form, described compressive layer (i.e. primer) is made up of following parts by weight raw material: 100 parts of chloroprene rubbers, 10-20 part staple fibre, the polynite of 8-15 part organic modified nano, 0.4-0.6 part stearic acid, 2-4 part anti-aging agent, 5-8 part zinc oxide, 4-6 part magnesium oxide and 2-5 part tenderizers.
As preferably, described staple fibre is one or more in aramid fiber short fibre, nylon staple peacekeeping polypropene staple.
Adding of machine modified nano montmorillonite alternative carbon black can carry out enhancement to chloroprene rubber matrix, but mineral filler add the toughness that simultaneously can reduce chloroprene rubber, therefore the present invention adopts appropriate staple fibre to increase the flexibility of chloroprene rubber, makes it have high strength and the warping strength fatigue property of height simultaneously.
After staple fibre adds chloroprene rubber, the flexibility of chloroprene rubber and the rigidity of fiber are organically combined, the snappiness of chloroprene rubber can be kept, make again chloroprene rubber be provided with the feature of high-modulus under low elongation, make it laterally have enough rigidity, longitudinally there is higher flexibility.But the addition of staple fibre should be suitable, add very few, then toughening effect is not obvious; Add too much, staple fibre is inclined to boundling in the base, is difficult to be uniformly dispersed, thus affects its toughening effect.
As preferably, the preparation method of described organic modified nano polynite is: polynite joins in aqueous ethanolic solution by (1), and makes it fully disperse under strong stirring; (2) step (1) gained mixed solution is heated to 65-75 DEG C, adds silane coupling agent, and adopt oxalic acid regulation system PH to 3-4, after insulation reaction 1-3 hour, be cooled to normal temperature and suction filtration; (3) get step (2) gained filter cake washing 2-3 time after, drying, grinding, mistake 100 mesh sieves namely obtain organic modified nano polynite.Because surface of inorganic particles generally has wetting ability, with hydrophobic chloroprene rubber matrix, poor compatibility between the chloroprene rubber matrix of particularly nonpolar or low-pole, therefore the interface adhesiveness of rubber/inorganic particle composite material is weak, directly causes the mechanical property of matrix material undesirable.For preparing high performance chloroprene rubber/inorganic particle composite material, modification must be carried out to surface of inorganic particles, realizing the bonds well of particle surface and chloroprene rubber matrix, thus obtaining the matrix material of excellent property.
More preferably, described in step (1), the massfraction of aqueous ethanolic solution is 30-40%, and the quality of described aqueous ethanolic solution is 2-4 times of polynite quality.
More preferably, described in step (2), silane coupling agent is selected from the one in KH550, KH560 and KH570.
More preferably, the quality that feeds intake of silane coupling agent described in step (2) is 0.2-0.4 times of polynite quality.
Beneficial effect of the present invention is:
Full neoprene latex Wide-angle cloth V provided by the present invention is with, adopt organic modified nano polynite and staple fibre composite modified, improve the intensity of V band, flexibility and warping strength fatigue property simultaneously.
