Problems solved by technology

[0002] Traditional EPDM waterproof membranes are mostly bonded with adhesives and adhesive tapes. This bonding method has the disadvantage that the overlapping parts of the membranes are not bonded firmly, and cracks are prone to appear, which affects the overall quality of the membranes. Waterproof effect, unable to form an overall waterproof layer, and the adhesive and adhesive tape cannot have the same lifespan as the main body coil

Embodiment Construction

[0008] A heat-welded EPDM waterproof membrane is produced from raw materials POE, EPDM rubber, APP, light calcium carbonate, carbon black, chlorinated paraffin, DOP, sulfur, anti-aging agent, and TMTD. Add to the banburying, the banburying time is 12 minutes, the banburying temperature is 130-150 degrees, so that the mixing is uniform, the material is discharged, the glue is poured on the 560 open mixer, the temperature is lowered to ≤90 degrees, and the sliver is removed, and the glue is filtered Machine to filter impurities, carry out thinning and mixing on the 450 open mill, after mixing evenly, the strips will be rolled out, extruded by the extruder, and the formed coils will pass through a 20-meter-long continuous vulcanization tank at 160 degrees and 0.3Mpa condition vulcanization, ie the finished product.

[0009] The parts by weight of raw materials are raw materials POE (100), EPDM rubber (100), APP (100), light calcium carbonate (230), carbon black (45), chlorinated ...

Abstract

The invention discloses a thermal welding ethylene-propylene-diene rubber waterproof coiled material which is produced by raw materials of POE, ethylene-propylene-diene rubber, APP, light calcium carbonate, carbon black, chlorinated paraffin wax, DOP, sulfur, anti-aging agent and TMTD; the raw materials are put into a banburying device; the banburying time is 12 minutes, and the banburying temperature is 130 to 150 DEG C; the mixing is even; discharging is carried out, and the glue is poured on a 560 mill; strip discharging is carried out after the temperature is reduced to lower than or equal to 90 DEG C; the impurities are filtrated by a glue filtering machine and strip discharging is carried out after thinning and even mixing are carried out on a 450 mill; extrusion molding is carried out by an extruder; the molded coiled material goes through a continuous vulcanizing tank with the length of 20 meters and is vulcanized under 160 DEG C and 0.3 MPa, and then the finished product is produced; and the waterproof coiled material is an integrated waterproof layer which improves the adhesive strength.

Description

Technical field: [0001] The invention relates to a production method of a building waterproof material. Background technique: [0002] Traditional EPDM waterproof membranes are mostly bonded with adhesives and adhesive tapes. This bonding method has the disadvantage that the overlapping parts of the coils are not bonded firmly, and cracks are prone to appear, which affects the overall quality of the coils. The waterproof effect cannot form an integral waterproof layer, and the adhesive and adhesive tape cannot have the same life as the main body coil. Invention content: [0003] The object of the present invention is to provide a thermally welded EPDM waterproof roll material, which is an integral waterproof layer and has improved bonding strength. [0004] The purpose of the present invention can be achieved through the following schemes: [0005] A heat-welded EPDM waterproof membrane is produced from raw materials POE, EPDM rubber, APP, light calcium carbonate, carbon...
