Problems solved by technology
The products mainly include asphalt waterproof membrane and polymer waterproof membrane, but these types of waterproof membranes currently on the market will have heat resistance, weather resistance, ozone resistance, chemical corrosion resistance, and low temperature resistance in actual use. The flexibility and elastic-plastic properties are relatively weak, and the tear resistance is also relatively weak, so the service life is very short. Although there are so many weaknesses, due to the current lack of waterproof membrane technology, the options are very low.

Embodiment 1
[0020] A butyl rubber waterproof membrane is composed of the raw materials of the following components:
[0021]
[0022] The method for preparing the butyl rubber waterproof membrane of the present invention comprises the following processing steps:
[0023] a. Select a high-speed mixing mixer, add butyl rubber into it according to the formula amount, and start stirring.
[0024] b. After the above-mentioned step a is stirred evenly, all the vulcanizing agent, anti-aging agent, furnace black, calciumcarbonate, paraffin oil, accelerator and sulfur in the above-mentioned raw materials are put into the high-speed mixing mixer, and after stirring evenly, use refining The rubber machine is plasticized and then mixed, and the mixing temperature is controlled at 50-110°C.
[0025] c. When the temperature of the above mixed material is 70-90°C, use a two-roller calender to roll the material into a semi-finished waterproof membrane with a thickness of 1.1-1.4mm.

Abstract
The invention relates to the technical field of chemical engineering and provides a preparation method for a butyl rubber waterproof coil. The coil comprises the following raw materials: 95 to 105 parts of butyl rubber, 4 to 6 parts of a vulcanizing agent, 0.5 to 1.5 parts of an anti-aging agent, 65 to 75 parts of furnace black, 4 to 6 parts of calciumcarbonate, 5 to 7 parts of paraffin oil, 3 to 5 parts of a promoter and 1 to 2 parts of sulphur. The invention has the following beneficial effects: the preparation method has the advantages of convenient and simple preparation, environmental protection, no pollution, easy availability of the raw materials, low investment for equipment, high purity and convenient operation; and the prepared butyl rubber waterproof coil has a good usage effect and strong high temperature resistance and is safe and reliable.
Description
technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for preparing a butyl rubber waterproof coiled material. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. The products mainly include asphalt waterproof membrane and polymer waterproof membrane, but these types of waterproof membranes currently on the market will have heat resistance, weather resistance, ozone resistance, chemical corrosion resistance, and low temperature resistance in actual use. The flexibility and elastic-plastic properties are relatively weak, and the tear resistance is a...
