Composite waterproof coating composition

Abstract

The invention relates to a composite waterproof coating composition. A montmorillonite material modified by lauryl ammonium chloride and triethanolamine is adopted in the composite waterproof coating composition; and the modified montmorillonite material has good dispersibility, thickening property and thixotropy and is capable of improving the stability of the coating. In addition, a specific proportion of modified nanometer composite powder is also adopted in the coating composition, and the nanometer composite powder subjected to surface modification can effectively modify the strength, toughness and scraping resistance of coatings. All the components in the specific composition of the coating interact synergistically so that after forming films, the coating has good adhesiveness, strength, hardness and waterproof performance.

Description

technical field [0001] The application relates to a composite waterproof coating composition and a preparation method thereof. Background technique [0002] Traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, and sealing ointments, as well as rigid waterproof materials that are based on cement substrates and added waterproofing agents and other additives. Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature. At the same time, there are still the following problems: (1) Traditional waterproof coatings are not environmentally friendly, corrosive, have large shrinkage of their own materials, and poor puncture resistance; (2) Traditional waterproof coatings are less brushed, and it is difficult to detect missing brushes; (3) Traditional waterproof coatings The constructio...

Problems solved by technology

Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature.

At the same time, there are still the following problems: (1) Traditional waterproof coatings are not environmentally friendly, corrosive, have large shrinkage of their own materials, and poor puncture resistance; (2) Traditional waterproof coatings are less brushed, and it is difficult to detect missing brushes; (3) Traditional waterproof coatings The construction base surface has strict requirements and must meet the requirements of solidity, smoothness and drying, otherwise the quality of the project is difficult to guarantee; (4) The traditional waterproof coating process is simple, low in technical content, and easy to fake; (5) If the wall is painted with a large area of ​​waterproof coating, It is difficult to guarantee the requirement of pasting large-size decorative bricks on the facade

Traditional waterproof coatings are used for roof waterproofing, which is easy to cause aging, cracking, deformation, breaking, and delamination; for indoor waterproofing, it is difficult to construct for places with complex shapes, and it is even more difficult to guarantee the quality of leakage. It takes a lot of money and labor to repair every few years, which not only disrupts people's normal life, work and production order, but also affects the service life of the entire building.
