Problems solved by technology

[0002] At present, the traditional rubber waterproof sheet is a fully vulcanized sheet, which is bonded with adhesive or adhesive tape. This bonding method has the problem that the overlapping parts of the sheet are not bonded firmly, and cracking is prone to occur, which affects the roll. The overall waterproof effect of the material cannot form an overall waterproof layer
And the adhesive and adhesive tape cannot have the same life as the body coil

Embodiment Construction

[0007] A kind of preparation method of TZ-SBSEC welded type rubber waterproof sheet is made of SBS (1401), EPDM (4770 type), CPE (135A), light calcium carbonate, carbon black N330, DOP, modifier TP-10 , sulfur, antioxidant RD, antioxidant 4010, TMTD, SBS (1401), EPDM (4770 type), CPE (135A), light calcium carbonate, carbon black N330, DOP, modifier TP-10, sulfur, The weight ratio of anti-aging agent RD, anti-aging agent 4010, and TMTD is 100:100:100:230:45:15:2:3:5:5:2.5, and SBS, EPDM, and CPE are added to the banburying according to the formula ratio, The refining temperature is 90-105°C, the banburying time is 3min, then sequentially add modifier TP-10, anti-aging agent 4010, anti-aging agent RD for 1.5min at the same temperature, and finally add light calcium carbonate, carbon black 330N, DOP The mixing temperature is 135-145°C, and the time is 9min, so that it is mixed evenly, and the material is discharged. The glue is poured on the S(X)K-560 rubber mixer, the temperatur...

Abstract

The invention discloses a method for preparing a TZ-SBSEC welding type rubber waterproof sheet. The TZ-SBSEC welding type rubber waterproof sheet consists of SBS (1401), EPDM (4770), CPE (135A), precipitated calcium carbonate, carbon black N330, DOP, a modifier TP-10, sulfur, an age inhibiter RD, an age inhibitor 4010, and TMTD. The preparation method comprises the following steps: adding the SBS, the EPDM and the CPE according to formula proportion into a banbury mixer at a banburying temperature of between 90 and 105 DEG C for 30 min; orderly adding the modifier TP-10, the age inhibiter RD, the age inhibitor 4010 for banburying at the same banburying temperature for 1.5min; finally adding the precipitated calcium carbonate, the carbon black N330 and the DOP at a banburying temperature of between 135 and 145 DEG C for 9 min for even banburying, and discharging; performing rubber reversing on an S(X)K-560 rubber mixing machine, reducing the temperature to less than or equal to 90 DEG C, and discharging strips; filtering impurities by a rubber strainer, performing thinning and mixing on a 450 mill mixer, and discharging strips after even mixing; performing extrusion molding by an extruder, and vulcanizing the formed coiled material in a 20m continuous vulcanizing boiler at 160 DEG C and 0.3MPa; and finally rolling and packaging. The method solves the problem of cold adhesion in construction of the rubber waterproof sheet, and makes the rubber waterproof sheet form an integral waterproof layer.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a preparation method of a TZ-SBSEC welded rubber waterproof sheet. Background technique [0002] At present, the traditional rubber waterproof sheet is a fully vulcanized sheet, which is bonded with adhesive or adhesive tape. This bonding method has the problem that the overlapping parts of the sheet are not bonded firmly, and cracking is prone to occur, which affects the roll. The overall waterproof effect of the material cannot form an overall waterproof layer. And the adhesive and adhesive tape cannot have the same lifespan as the body coil. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of TZ-SBSEC welded rubber waterproof sheet. [0004] The technical scheme adopted in the present invention is: a kind of preparation method of TZ-SBSEC welded rubber waterproof sheet, is made of SBS (1401), EPDM (4770 type), CPE (...
