Abstract

The invention discloses two-component waterproof acid-proof paint as well as a preparation method and an application thereof. The two-component waterproof acid-proof paint is composed of a component A and a component B, wherein the component A comprises the following components in parts by weight: 30-40 parts of acrylic resin, 5-10 parts of hydrophobic organic silicon resin, 5-9 parts of alkaline filler, 1-3 parts of coupling agent, 0.5-1 part of anti-settling agent, 0.1-0.3 part of defoaming agent, 0.5-1.0 part of dispersing agent, 15-25 parts of colouring pigment filler and 20-25 parts of first organic solvent, the component B comprises the following components in parts by weight: 20-24 parts of polyurethane curing agent and 9-11 part of second organic solvent. The two-component waterproof acid-proof paint has good low temperature malleability and low water absorption, can effectively absorb acidic materials and has an effect of preventing concrete from being in ageing failure too fast when being coated on the surface of the concrete.

Description

technical field

[0001] The invention relates to the field of coatings, in particular to a waterproof and acid-resistant coating as well as its preparation method and application. Background technique

[0002] Concrete is the most widely used and used building material in modern society, but if it is exposed to the natural environment for a long time, it will age or even be damaged due to various factors. At present, some concrete engineering projects mainly improve the performance of concrete itself, standardize the construction and maintenance of concrete, and prolong the service life of concrete by constructing surface protective coatings.

[0003] There are mainly two types of materials for surface protection coatings: one is silicone-based silane-impregnated materials, and the other is organic coatings with a certain film thickness. The former type of material is mainly used in the protection of marine underwater concrete, which is expensive, difficult to construct, and...
