Abstract
The utility model relates to a polyvinyl chloride poly V-ribbed belt with a basalt fiber rope core, comprising a core rope, core adhesive, wedge adhesive and top cloth, wherein a basalt fiber core rope is arranged in the core adhesive; the basalt fiber core rope consists of basalt fiber core string and a cover layer; the basalt fiber core string is twisted by strands of basalt fiber twistless roving; and the cover layer is a polyvinyl chloride cover layer. As the basalt fiber core rope is arranged in the core adhesive, the V-ribbed belt is higher in strength, the belt body is softer, the weight is light, the elongation of the belt is lower than that of a fabric canvas flat transmission belt, and the heat resistance is better, compared with high-technology fiber, the price is lower, and the cost performance is better; and as the basalt fiber core rope is subjected to polyvinyl chloride covering treatment, the loss of tensile strength due to fragility and fracture of fiber in the belt manufacturing process of the basalt fiber rope core is effectively reduced, and meanwhile, the bonding strength of the rope core and the polyvinyl chloride core adhesive is increased.
Description
Technical field
The utility model relates to the driving belt that a kind of equipment is used, and particularly relates to a kind of PVC poly Vbelt that has the basalt fibre wire rope core.
Background technique
The poly Vbelt of existing technology generally uses as driving belt; Its inside is with the tension element of wire rope as driving belt; The fracture great majority of driving belt are owing to Steel cord corrosion fracture causes; And big with wire rope as the tension element weight of driving belt, consume the more powerful, energy-conservation inadequately of traction electric machine; Also have at present and use aramid fibre, superhigh molecular weight polyethylene fibers wire rope core to produce driving belt, but cost is high as tension element.
Summary of the invention
The purpose of the utility model is exactly the defective that overcomes present driving belt, and a kind of PVC poly Vbelt that has the basalt fibre wire rope core is provided.
For achieving the above object, the utility model adopts following technological scheme:
A kind of PVC poly Vbelt that has the basalt fibre wire rope core; Comprise: core rope, core glue, wedge glue, top cloth; Be provided with basalt fibre core rope in the described core glue; Described basalt fibre core rope is made up of basalt fibre heart yearn and clad, and described basalt fibre heart yearn is the heart yearn of basalt fibre roving Split Down twisting, and described clad is the PVC clad.
Described core glue and wedge glue are that the degree of polymerization is at the Corvic more than 1150.
Described top cloth is the fabric canvas, and the fabric canvas is provided with the coating of PVC paste resin.
The beneficial effect of the utility model: owing to be provided with basalt fibre core rope in the core glue of driving belt; Basalt fibre core rope is fibrous by basalt (CBF), and the tensile strength of basalt (CBF) fiber is 4450～4800MPa, and is all higher than large-tow carbon fiber, aramid fibre, Steel Fibre; The core rope that utilizes basalt fibre roving twisting Split Down to process has high tenacity, high-modulus, good heat resistance, characteristics that elongation percentage is low; Replace Steel cord to produce poly Vbelt as tension element, its tensile strength is higher, elongation percentage is lower, weight lighter (proportion be merely steel 1/3); Compare with the Steel cord poly Vbelt as the poly Vbelt of tension element manufacturing with the basalt fibre wire rope core; Its intensity is higher, belt body is more soft, can significantly reduce the weight of poly Vbelt, uses the poly Vbelt of high technology fiber (aramid fibre, superhigh molecular weight polyethylene fibers) wire rope core production to compare with other; Its price is lower, and cost performance is better; Because the basalt fibre wire rope core is to be added by the Split Down of basalt fibre roving to be twisted into; The basalt fibre wire rope core coats through PVC and handles; Can effectively reduce the basalt fibre wire rope core in system band process; Fracture easily because of fibrous is crisp and to cause the loss of tensile strength, increased the bonding strength of wire rope core and polyvinylchloride core glue simultaneously.
Description of drawings
Fig. 1 is one of them embodiment's of the utility model a cross section stereo schematic representation.
Embodiment
Can find out with reference to Fig. 1; The utility model comprises: core rope 2, core glue 3, wedge glue 4, top cloth 1; Be provided with basalt fibre core rope in the described core glue; Described basalt fibre core rope is made up of basalt fibre heart yearn and clad, and described basalt fibre heart yearn is the heart yearn of basalt fibre roving Split Down twisting, and described clad is the PVC clad.Described core glue 3 is that the degree of polymerization is at the Corvic more than 1150 with wedge glue 4.Described top cloth is the fabric canvas, and the fabric canvas is provided with the coating of PVC paste resin.The described PVC clad of the utility model is that the basalt fibre heart yearn coats the very thin melt of one deck (coating thickness is about 0.08mm) through extruder around heart yearn; Process through the tank slow cooling again; Use has the basalt fibre core rope of clad, and not only driving belt intensity is high, and because the clad with basalt fibre wire rope core tension element of band colloid is a same material; Both can well combine, thereby have increased the bonding strength of wire rope core and core glue.The poly Vbelt of the utility model comprises annular poly Vbelt and ports having (two ports are arranged, do not circularize) poly Vbelt.
