[0069] Preparation of butyl rubber

[0070] Heat 42kg of 150# aromatic hydrocarbon oil to 155°C, add 35kg of 1502 styrene-butadiene rubber and 5kg of SBS, then stir at a speed of 1000rpm for 30min, then increase the temperature of the mixed system to 180°C and stir at a speed of 1500rpm for 3h, then Add 2kg of wax powder and stir at a speed of 1500rpm for 0.5h, then grind until the system has no particles, finally add 16kg of 200 mesh talc powder and stir for 1h to make the system evenly mixed, and cool to room temperature to obtain butyl rubber.

preparation Embodiment 1

[0074] The specific composition of each raw material of the sizing material is shown in Table 1 below, and its preparation method includes the following steps.

[0075] (1) Mix the oil and asphalt evenly at 120°C;

[0076] (2) Heating the mixture obtained in the step (1) to 160° C., then adding SBS under agitation and mixing uniformly;

[0077] (3) Continue to add butyl rubber, SBR, lignin, tackifying resin and filler and stir for 100 minutes at a temperature of 165°C to make it evenly mixed;

[0078] (4) Grinding the mixed system obtained in the step (3) to a particle size of 0.3mm and continuing to stir for 5min;

[0079] (5) Add talcum powder to the mixed system after grinding in the step (4) and stir for 60 minutes to make the system evenly mixed, then cool down to room temperature and finally discharge to obtain the rubber compound of the present invention, which is recorded as A1.

Abstract

The invention discloses a sizing material for improving the stripping performance and construction applicability of an S-CLF YC type coiled material. The sizing material obtained by compounding asphalt, an oil product, SBS, butyl rubber, SBR, lignin, tackifying resin and stone powder in a specific range can overcome the defect that the stripping strength of the coiled material and post-cast concrete does not meet the requirement. And the S-CLF YC type waterproof coiled material is smooth in appearance, the phenomena of sand surface and yellowing of the coiled material under a high-temperature condition are not easily caused, and meanwhile, it is ensured that other properties meet the standard requirements. The performance of the coiled material is improved, and the market competitiveness of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of building material production, and in particular relates to a rubber material for improving the stripping performance and construction applicability of S-CLF YC type coils. In addition, the present invention also relates to a preparation method of the rubber compound. Background technique [0002] Waterproof membranes have developed very rapidly since the 1980s. Because of their advantages such as light weight, high tensile strength, high elongation, good weather resistance, large operating temperature range, and low pollution, they have gradually become very common in modern buildings. One of the most popular building materials, it is mainly used for building walls, roofs, tunnels, roads, landfills, etc., and can resist external rainwater and groundwater leakage. It is used as a link between the engineering foundation and the building. The leak-free connection is the first barrier for the waterproofing o...
