The water-based rubber asphalt waterproof sealant of the present invention has all technical performance indicators up to the standard, does not use organic volatile solvents such as benzene and ketones in production, realizes environmental protection in production, construction and application, and has long-term The development plan is of far-reaching significance for the benefit of future generations.

Description

technical field [0001] The invention relates to a waterproof sealant, in particular to a water-based rubber asphalt waterproof sealant. technical background [0002] Waterproof sealant is a kind of sealing material with waterproof function, which can prevent the intrusion of liquid, gas and solid, and can play the role of watertight and airtight. Traditional waterproof sealants are mainly divided into solvent-free, solvent-based and emulsion-based. Solvent-based waterproof sealants contain solvents that are volatile, toxic and harmful, and are very harmful to the human body and the atmospheric environment. Solvent-free waterproof sealants are mostly composed of silicone rubber, polysulfide rubber, and sulfide rubber. Although they do not contain solvents, the materials themselves are odorous and harmful to the human body and the atmospheric environment. Emulsion-type waterproof sealant is composed of acrylic and butyl rubber. Although it does not contain solvent, it is non...
