Problems solved by technology

The above-mentioned waterproof coating also has problems such as high cost, complicated preparation process, low solid content, and more organic volatiles, which will bring difficulties to a thick film construction and bring great pollution to the environment.
In addition, most of the curing agents used in existing high-performance polyurethane waterproof coatings are MOCA and MOCA, which will bring great harm to human health.

Abstract

The invention provides a waterproof coating for decoration engineering and a preparation method thereof. The waterproof coating is prepared from the following components: a modified butyl acrylate emulsion, ethyl silicate, castor oil, talc powder, titanium dioxide, graphene, anhydrous ethanol, dimethylethanolamine, dibutyltin dilaurate, a polymerization inhibitor, a defoamer, a coalescing agent and deionized water. The waterproof coating prepared by the invention has excellent bonding strength, waterproof performance, impact resistance and stability.

Description

technical field [0001] The invention belongs to the technical field of decoration materials, and in particular relates to a waterproof coating for decoration engineering and a preparation method thereof. Background technique [0002] At present, there are two main types of waterproof materials: one is polyurethane waterproof coating, which is made of polyurethane as the basic component and additives such as coal tar and asphalt. This type of material has a dense coating film and good waterproof performance, but it contains many toxic solvents. When the smell is strong. The other is polymer cement-based waterproof coating, which is a waterproof coating composed of organic liquid material and inorganic powder. Excellent in stability, non-toxic and environmentally friendly. However, the current polymer cement-based waterproof coatings have poor impermeability and short impermeability time, are prone to aging, and are prone to leakage during use. [0003] The publication numb...
