Problems solved by technology

However, the non-curing rubber asphalt waterproof coating contains asphalt, so the color is usually single and black; the low temperature flexibility is poor, it can only reach -20°C, the elongation performance is poor, and the aging resistance is poor
In addition, non-curing waterproof coatings need to be heated during the construction process, so some of the components will produce smoke at high temperatures, which is not environmentally friendly

Abstract

The invention provides a smokeless non-curing rubber waterproof coating. The waterproof coating is mainly composed of extracted oil, C9 petroleum resin increases the adhesive force of the coating, SBS improves the high temperature resistance and low temperature resistance of the coating, and SBR increases the peeling strength. Improve the adhesion between the coating and the substrate. Polypropylene wax and polyethylene wax have the functions of dispersing and lubricating, effectively reducing the viscosity of the coating, so that the obtained waterproof coating can be sprayed when heated to 130 °C during the construction process. In addition, polypropylene wax and polyethylene wax can be used as carriers to improve the compatibility between SBS, SBR and extracted oil, and reduce the accumulation of molecules, thereby ensuring The resulting coating is more uniform and can be heated evenly during construction, further reducing the generation of smoke and dust. The invention improves the low-temperature flexibility and aging resistance of the waterproof coating through the interaction between the components.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a smokeless non-curing rubber waterproof coating and a preparation method thereof. Background technique [0002] Waterproof coatings are generally made of asphalt, synthetic polymers, synthetic polymers and asphalt as the main film-forming substances, mixed with an appropriate amount of pigments, additives, solvents, etc., which are solvent-based, water-emulsion or Reactive type, a polymer synthetic material that is an amorphous viscous liquid or liquefiable solid powder at room temperature. In the process of using waterproof coating, it is alone or combined with carcass reinforcement material, brushed or sprayed on the surface of the substrate that needs to be waterproofed to form a continuous, seamless, integral and waterproof coating with a certain thickness. [0003] Waterproof coatings are generally divided into asphalt-based waterproof coatings, polymer-modifi...
