Problems solved by technology

[0002] At present, the traditional chlorinated polyethylene rubber-plastic blended waterproof membranes are mostly bonded with adhesives and adhesive tapes. This bonding method has the disadvantages that the overlapping parts of the coils are not bonded firmly and are prone to cracking, which affects the The overall waterproof effect of the membrane 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 preparation method of TZ-PSBSR thermally welded rubber-plastic blended waterproof membrane, which is composed of POE (7380), styrene-butadiene rubber (1502), SBS (1401), light calcium carbonate, carbon black N330, modifier TP -10, DOP, sulfur, antioxidant RD, TMTD, antioxidant 4010, POE (7380), styrene-butadiene rubber (1502), SBS (1401), light calcium carbonate, carbon black N330, modifier TP-10 , DOP, sulfur, anti-aging agent RD, TMTD, anti-aging agent 4010 weight ratio is 100: 100: 100: 320: 65: 2: 15: 3: 5: 5: 2.5, all raw materials are added to the banburying according to the formula ratio , the banburying time is 9min, and the banburying temperature is 130-150°C, so that it can be mixed evenly and then discharged. The glue is poured on the 560 open mill, the temperature is lowered to ≤90°C, and then the strips are unloaded. The impurities are filtered through the filter rubber machine, and the strips are thinned and mixed on the 450 open mill. After the mixing i...

Abstract

The invention discloses a method for preparing a TZ-PSBSR soldering rubber blended waterproof coiled material. The TZ-PSBSR soldering rubber blended waterproof coiled material consists of POE (7380), styrene-butadiene rubber (1502), SBS (1401), precipitated calcium carbonate, carbon black N330, DOP, sulfur, an age inhibiter RD, TMTD, and an age inhibiter 4010. The preparation method comprises the following steps: adding all raw materials in formula proportion into a banbury machine for banburying at a temperature of between 130 and 150 DEG C for 9min, evenly mixing the raw materials, and discharging; performing rubber reversing on a 560 mill mixer, reducing the temperature to less than or equal to 90 DEG C to discharge 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 adhesion of the rubber blended waterproof coiled material so as to make the rubber blended waterproof coiled material 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-PSBSR thermally welded rubber-plastic blended waterproof coiled material. Background technique [0002] At present, the traditional chlorinated polyethylene rubber-plastic blended waterproof membranes are mostly bonded with adhesives and adhesive tapes. This bonding method has the disadvantages that the overlapping parts of the coils are not bonded firmly and are prone to cracking, which affects the The overall waterproof effect of the membrane 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 object of the present invention is to provide a method for preparing a TZ-PSBSR thermally welded rubber-plastic blended waterproof membrane. [0004] The technical solution adopted by the present invention is: a preparation method of TZ-PSBSR heat...
