Abstract

The invention relates to low-VOC (volatile organic compound)-content low-temperature-resistant solvent type rubber asphalt waterproof paint, which is prepared from the following raw materials in parts by weight: 90 to 110 parts of asphalt, 5 to 15 parts of softening agents, 10 to 30 parts of SBS, 0 to 3 parts of modifiers, 20 to 40 parts of filling agents and 60 to 80 parts of solvents. The invention also provides a preparation method of the low-VOC-content low-temperature-resistant solvent type rubber asphalt waterproof paint. The low-temperature-resistant performance of a product provided by the invention is obviously improved; the product application range is improved; the product VOC content is reduced; the environment-friendly application effect of the product is obviously improved; the product proportioning time is shortened; the product proportioning temperature is lowered; the heat loss in the product temperature reduction process is reduced; the energy is saved; the emission is reduced; meanwhile, the defects of low dissolution dispersion speed of a high modifier addition of asphalt paint and easy polymerization in long-time modification can be solved; the defect of obvious reduction of performance after the dilution of modified asphalt by a solvent is overcome.

Description

technical field [0001] The invention relates to a rubber asphalt waterproof coating and a preparation method thereof, in particular to a low-VOC content low-temperature solvent-resistant rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] Solvent-based rubber asphalt waterproof coating, as a member of asphalt coatings, has been widely recognized by the market for its characteristics of no flow at high temperature, no cracking at low temperature, strong weather resistance, acid resistance, and strong crack resistance. Due to the rapid curing of the material, it can be constructed at room temperature or at a lower temperature. The product forms a continuous closed system without joints or joints after spraying or scraping. It is firmly bonded on various dry base surfaces such as roof, plane, elevation, and slope, and is often used in combination with waterproof membranes, thereby solving the problem of single waterproof membranes d...
