High-solid-content solvent type non-curing rubber asphalt waterproof paint and preparation method thereof

Abstract

The invention discloses a high-solid-content solvent type non-curing rubber asphalt waterproof paint which is prepared by mixing the following ingredients in weight percentage: 20-65 percent of softening oil, 3-20 percent of thermoplastic styrene butadiene rubber, 5-25 percent of rubber powder, 3-20 percent of a bonding modifier, 13-58 percent of asphalt, 10-30 percent of solvent oil and 0.3-1.0 percent of a compatilizer. The waterproof paint can be used under the construction condition of below 30-50 DEG C, the construction is simple, and the high-temperature heat resistance in summer and the low-temperature elasticity in winter are high. The waterproof paint has high heat-resistant liquidity, always keeps in an elastic-plastic colloidal state in the entire service life, is suitable for any forms of underlayer base surfaces, and can cut down the engineering time substantially. The invention further discloses a preparation method of the high-solid-content solvent type non-curing rubber asphalt waterproof paint.

Description

technical field [0001] The invention relates to a waterproof coating used in the construction industry, in particular to a high-solid-content solvent-type non-curing rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] At present, the materials used in waterproofing projects mainly include waterproof coiled materials, film-coated waterproof coatings, and emulsion rubber waterproof materials. During the construction of the waterproof membrane, a hot-melt spray gun is used to melt the adhesive surface of the membrane. The construction is difficult and the construction time is long. If there is water leakage after construction, the water will flow along the adhesive surface and damage the membrane in other areas. Leakage points must be re-constructed. [0003] Coating film waterproofing is spraying construction, construction is simple, convenient, and film thickness is uniform. After construction, it needs to be hardened and dried, ...

AI Technical Summary

Problems solved by technology

During the construction of the waterproof membrane, a hot-melt spray gun is used to melt the adhesive surface of the membrane. The construction is difficult and the construction time is long. If there is water leakage after construction, the water will flow along the adhesive surface and damage the membrane in other areas. Leakage points must be re-constructed

[0003] Coating film waterproofing is spraying construction, construction is simple, convenient, and film thickness is uniform. After construction, it needs to be hardened and dried, and the project progress is correspondingly extended. Water-based coating film waterproof materials cannot be constructed in winter. After construction, the hardened and dried waterproof coating film layer is fixed and bonded In the bottom layer, when cracks occur in the civil structure, the coating layer has poor flexibility and no extensibility, resulting in cracks and water leakage in the waterproof layer of the coating film.

[0004] Cement and emulsified glue waterproofing materials need to be applied manually. The construction period is long, the application thickness is uneven, the construction quality is poor, and the cost is high. When constructing vertical civil structures in summer, due to the high temperature, the emulsion applied on the upper part will flow backwards, resulting in waterproofing. Uneven layer thickness, waterproof membrane falling off, etc.
