Scratching-resistant waterproof coating compound

Abstract

The invention relates to a scratching-resistant waterproof coating compound. The scratching-resistant waterproof coating compound is made of a montmorillonite material modified by lauryl ammonium chloride and triethanolamine, and the modified montmorillonite material is excellent in dispersity, thickening performance and thixotropy and capable of improving stability of the coating compound. By adoption of modified nano compound powder in specific ratio, coating strength, toughness and scratching resistance can be effectively improved after the nano compound powder is subjected to surface modification. Owing to mutual synergy of specific compositions of the coating compound, the scratching-resistant waterproof coating compound is high in adhesiveness, strength, hardness and water resistance after film formation.

Description

technical field [0001] The application relates to a scratch-resistant 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 con...

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.
