Abstract

The invention discloses a self-permeability-increasing high-permeability acid-resistant epoxy resin waterproof coating material and a preparation method therefor. The self-permeability-increasing high-permeability acid-resistant epoxy resin waterproof coating material consists of a component A and a component B, wherein the component A is prepared from epoxy resin, a fluorinated organosilicone modified epoxy reactive diluent and a carbonyl compound, and the component B is prepared from polyamine, a silane coupler and an accelerant. The self-permeability-increasing high-permeability acid-resistant epoxy resin waterproof coating material is good in permeability, plays dual roles in preventing seepage and reinforcing and has good acid resistance and low-temperature flexibility.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, in particular to a self-increasing permeable high-permeability acid-resistant epoxy resin waterproof coating and a preparation method thereof. Background technique [0002] In recent years, with the advancement of urbanization, various infrastructures and public works are under construction in full swing. In the buildings that have been built or are under construction, the anti-seepage and anti-corrosion properties of concrete are particularly important. Concrete itself is a non-uniform porous material, and it is prone to local cracking after construction. Such problems need to be solved through certain waterproof and anti-corrosion measures. [0003] At present, the traditional methods used in engineering are mainly asphalt waterproof coiled materials, polyurethane waterproof materials, and ordinary epoxy waterproof coatings. However, they all have the problem that they cannot penet...
