The invention selects the components and the proportion of the raw materials to obtain the permeable waterproof agent which takes the illegal cooking oil as the raw material and has excellent waterproof effect. The raw materials of the invention are emulsified by reaction to form non-ionic emulsion, and most of the colloidal particles are very hydrophobic. The grease particles and rosin particles can react with calcium hydroxide, which is a hydration product of cement or concrete, to form an insoluble calcium soap complex adsorption layer and an oily substance resolved in the reaction process, so that the concrete and products thereof are compact and waterproof. Due to the strong nonionic characteristic, the emulsion can penetrate into the inner layer through pores on the surface layer, and the oily particles and the calcium soap complex in the emulsion are attached to cement or concrete from the surface layer to the inner layer in the penetration process to form a compact calcium soap surface layer, thereby playing the excellent roles of water prevention and seepage prevention. In addition, the oily substance is resolved in the reaction process, so the dosage is greatly saved and the effect is excellent. The characteristics include: high flexibility, water and moisture resistance, strong adhesion, cracking resistance, air permeability and impermeability. The invention adopts the gutter oil as the main raw material, has simple preparation method, easily obtained raw materials, less investment, environmental protection, strong high temperature resistance and extremely simple construction method. By adopting the invention, the recycling benefit of the illegal cooking oil can be improved by 8-10 times, and the illegal cooking oil is prevented from flowing back to the dining table and harming health.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
