Abstract

The invention specifically relates to an asphalt-based flexible isolated layer material as well as a production method thereof. The material provided by the invention is prepared from asphalt, filler A, filler B, a solvent A and a solvent B which are compounded in a certain proportion and produced and processed. The material provided by the invention has good strong acid resistance, alkali resistance and acid-base alternating corrosion resistance. Meanwhile, the material has extremely good flexibility and overcomes the problem that buildings crack due to different coefficients of expansion and contraction caused by poor toughness of the isolated layer used in a sulfuric acid dry absorption tower and tanks. The performance of the isolated layer or the anti-corrosion coating is improved and the service life of the material is prolonged. At the same time, after being unpacked the product provided by the invention can be immediately used without being decocted in the field, thereby greatly reducing the environmental pollution generated by field decoction of a common asphalt material, and omitting the pre-treatment process of the asphalt material in a construction operation. The material has good construction convenience, so the construction period can be shortened and the construction cost is lowered.

Description

technical field [0001] The invention relates to the technical field of industrial anticorrosion, in particular to an asphalt-based flexible isolation layer material and a production method thereof. Background technique [0002] Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material, which can be used as an anti-corrosion coating material for buildings, a primer in concrete construction, and an isolation layer material for reaction towers or tanks. It is currently widely used in coatings, Plastic, rubber and other industries and road paving, etc. Traditional asphalt materials need complex pretreatment processes such as on-site boiling, batching, and mixing before use, and are affected by temperature, proportioning, raw material control, etc., which not only requires high operating requirements, inconvenient construction, but also pollutes the environment. [0003] There are many types and models of asphalt materials or modified asphalt-based mate...
