The load-transfer device that is used for cement industry of the utility model; The manufacture craft of said driving surface rubber cover may further comprise the steps successively: adopt the contrary method of mixing; At first compounding ingredients such as active agent, aging inhibitor, reinforcing agent, soften flux are added Banbury mixer; Then ethylene propylene diene rubber (EPDM), ethylene-propylene diene reclaimed rubber (R-EPDM) and poly-chloroprene rubber (CR) are added mixer mixing, mixingly be processed into one section sizing material; The mixing one section sizing material that parks is carried out two-stage mixing, and one section sizing material drops into Banbury mixer earlier, adds refining medicine eventually such as crosslinking agent, assistant crosslinking agent then, and mixing even back discharge makes the finished composition material; And then the finished composition material that makes more than the handle rolls into film through heat refining; Film is a band embryo half-blank with the powerful special high temperature resistant skeleton belt carcass assembly of integrally stretching that provides that posts, and is modified to finished product through high temperature vulcanized, inspection then.
The manufacture craft of driving surface rubber cover mainly is to adopt the contrary method of mixing in the utility model; Earlier compounding ingredients such as active agent, aging inhibitor, reinforcing agent, soften flux are added Banbury mixer; Then ethylene propylene diene rubber (EPDM), ethylene-propylene diene reclaimed rubber (R-EPDM) and poly-chloroprene rubber (CR) are added mixer mixing, mixingly be processed into one section glue; The mixing one section sizing material that parks is carried out two-stage mixing, and one section sizing material drops into Banbury mixer earlier, adds refining medicine eventually such as crosslinking agent, assistant crosslinking agent then, and mixing even back discharge makes the finished composition material; And then the finished composition material that makes more than the handle rolls into film through heat refining; Film is a band embryo half-blank with the powerful indeformable skeleton belt carcass of the special high temperature assembly of integrally stretching that provides that posts, and is modified to finished product through high temperature vulcanized, inspection then.The utlity model has excellent ageing-resistant, freedom from cracking wear resisting property, satisfied the requirement that cement industry is carried high-temperature material; The utility model has adopted the EPDM reclaimed rubber and has used the part ethylene propylene diene rubber in addition, has improved the performance of technical process of sizing material, has improved the sticking and performance of EPDM sizing material, and the utilization of renewable resource has met the requirement of low-carbon environment-friendly again.
Compared with prior art the beneficial effect of the utility model is: 1, the rubber cover of ethylene propylene diene rubber and EPDM reclaimed rubber and usefulness; Have excellent high temperature resistant ageing properties and ageing-resistant be full of cracks performance, satisfied iron and steel, cement industry high temperature is carried the working condition requirement of operation.2, the use of EPDM reclaimed rubber has improved the performance of technical process when manufacturing, and has improved the sticking and performance of sizing material, makes each parts in high temperate zone be able to firm combination.3, select for use the canvas of extraordinary high temperature resistant processing to solve the belt body problem on deformation under hot environment.4, improve the service life in high temperate zone, reduced the replacing frequency of belt, improved industry high temperature transport efficiencies such as iron and steel, cement.
Description of drawings
Fig. 1 is the constructional drawing of the utility model;
Fig. 2 is the flow scheme of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1; A kind of load-transfer device that is used for cement industry; Comprise the layer-stepping fabric core conveyor belt belt body that is combined as a whole through moulding and vulcanization process, the belt body structure down is followed successively by driving surface rubber cover 1, fabric core tension casing play 2, non-working surface rubber cover 3, rubber cover film 4 and casing play rubberizing canvas 5 from contact material driving surface.
