Said upward rubber cover 2, following rubber cover 3 are by any one or a few mixing the forming in natural rubber, butadiene-styrene rubber, the EP rubbers;
2, spiral steel mesh calendering
Core glue is rolled on upper and lower surface at spiral steel mesh 1 respectively, and the thickness of core glue is decided according to the binder removal amount of the spiral steel mesh of being selected for use;
Said core glue is by natural rubber and neoprene is mixing forms;
3, moulding
The said length that goes up covering 2, following rubber cover 3, limit glue 4 is all than the short 180-220 millimeter of the length of spiral steel mesh 1;
Said limit glue 4 is by any one or a few mixing the forming in natural rubber, butadiene-styrene rubber, the EP rubbers;
4, sulfuration
Made-up belt after the moulding delivered in the vulcanizer vulcanize, curing temperature is controlled at 130-180 degree centigrade, and sulfide stress is decided according to filter bag belt body width, and cure time is decided according to the thickness of made-up belt;
5, splicing
The two ends of spiral steel mesh 1 length direction connect as one through the joint that step 3 reserves, and cover rubber cover 2, following rubber cover 3 and limit glue 4 then respectively on the upper and lower surface of junction spiral steel mesh, vulcanize to be one;
In order further to increase the width of monolithic spiral steel mesh rubber strip belt body; During said step 3) moulding; The width one side setting of spiral steel mesh 1 and spiral steel mesh 1 uniform thickness widen parts 5, the width of widening parts is decided according to the actual requirements, the calendering that equal thickness is set again at the width opposite side of widening parts has the spiral steel mesh of core glue; Rubber cover on laying at last, the width of the width of upper and lower rubber cover=two a spiral steel mesh+the widen width of the width+limit glue of parts;
The said parts 5 of widening are to be processed by any one material in elastomeric material, mylar, the duck core.
A kind of spiral steel mesh rubber strip belt body preparation technology of the present invention; By the mode that the spiral steel mesh replaces polyester or duck core to make the rubber strip belt body, this mode of production has not only significantly strengthened the bulk strength of rubber strip belt body, and has simplified process of manufacture and joint style; Use this mode of production cost can reduce about 30% to product with intensity rank; This product percentage elongation is little, can layering in the use, increased the cost performance of rubber strip.
Description of drawings
The structural representation of a kind of spiral steel mesh rubber strip belt body of Fig. 1: embodiment 1;
The structural representation of a kind of spiral steel mesh rubber strip belt body of Fig. 2: embodiment 2.
The specific embodiment
Provide the specific embodiment of the present invention below with reference to accompanying drawing, be used for the present invention is done further explanation.
A kind of preparation technology of spiral steel mesh rubber strip belt body, the prepared belt body width that goes out is that 2800mm, thickness are that 25mm, length are 20mm, and it is the spiral steel mesh of 6mm that framework material is selected thickness for use, and rubber cover is selected ethylene propylene diene rubber EPDM for use.
Preparation technology is following:
1, rubber cover calendering
To go up rubber cover 2, descend rubber cover 3 to roll, the thickness that makes upper and lower rubber cover is 14-16mm;
Wherein, last rubber cover, down rubber cover is to be mainly to carry out mixing forming with other sizing material by ethylene propylene diene rubber;
2, spiral steel mesh calendering
Core glue is rolled on upper and lower surface at spiral steel mesh 1 respectively, and the thickness of calendering back core glue is 8mm;
Said core glue is by natural rubber and neoprene is mixing forms;
3, moulding
The spiral steel mesh lay that calendering is had the core glue material is on the moulding table top; Both sides at spiral steel mesh 1 length direction are provided with limit glue 4; Rubber cover 3, upper surface are laid rubber cover 2 under the lower surface of spiral steel mesh is laid; Last rubber cover 2, the length of rubber cover 3, limit glue 4 all is shorter than the length of spiral steel mesh 1 down, thereby makes the length direction two ends of spiral steel mesh 1 reserve joint, and last rubber cover 2, the length of rubber cover 3, limit glue 4 is all lacked the 180-220 millimeter than the length of spiral steel mesh 1 down;
Said limit glue material is with the rubber cover material is identical up and down;
4, sulfuration
Made-up belt after the moulding delivered in the vulcanizer vulcanize, curing temperature is controlled at 130-180 degree centigrade, and sulfide stress is controlled at 7-9Mpa, and cure time is 40-60 minute;
5, splicing
The spiral steel mesh that reserves 1 is connected as one through steel wire rope, rubber cover 2, rubber cover 3 down are set respectively on the upper and lower surface of spiral steel mesh 1 then, vulcanize and be one.
