Abstract
The invention relates to a method for preparing waterproof leakage-mending adhesive by utilizing waste polystyrene foam plastic. The method comprises the following steps: crushing the waste polystyrene foam plastic, adding isocyanate, dioctyl phthalate and a solvent, dissolving and standing for 20-30 hours and filtering to obtain a polystyrene foam plastic adhesive solution; adding phenolic resin, lime rosin, tung oil and a part of polymerized sub tung oil into a cooking pot to mix, raising the temperature to 175-180 DEG C, adding lead acetate, raising the temperature to 270-275 DEG C, carrying out heat preservation till the viscosity is 100-200 s, reducing the temperature, adding rest polymerized sub tung oil, cooling to 155-160 DEG C, adding No.200 solvent oil to dilute and filtering to obtain phenolic mixing paint; taking and mixing the polystyrene foam plastic adhesive solution and the phenolic mixing paint according to the mass ratio of 3:1, adding a defoaming agent, turpentine, a stabilizing agent, an antioxidant, a drying catalyst and a filler, uniformly mixing and grinding for 1-2 times by using a film machine. The waterproof leakage-mending adhesive obtained by the method has the advantages of high viscosity, good elasticity, good light, water and cold resistance and good convenience in use.
Description
technical field [0001] The invention relates to a method for preparing waterproof leak-trapping glue by using waste polystyrene foam plastics, and belongs to the technical field of waterproof glue preparation. Background technique [0002] At present, in order to prevent water leakage in buildings, chemical waterproofing agents are often added to concrete or mortar to increase the density to achieve waterproofing. Since chemical waterproofing agents are rigid waterproof materials, they have better anti-aging performance, but their crack resistance is poor. , Variability, will still lead to the phenomenon of building water leakage. [0003] Waterproof sealant glue is mainly used in building renovation waterproofing, roof leak repairing waterproofing, exterior wall waterproofing, indoor kitchen and bathroom waterproofing, pipeline leakage prevention and other waterproofing engineering constructions in building decoration. Waterproof sealants not only require good waterproof p...
