Abstract
The invention takes the acrylic ester emulsion as the main film forming matter, adds water-based polyurethane emulsion, butylbenzene emulsion and organosilicon emulsion as modifier, takes the water as solvent, adds other adjuvant and gets the product. The invention overcomes the limitation when only employing single macromolecular emulsion because it employs several macromolecular emulsion, which can cover the shortage each other. The invention is characterized in that it takes water as solvent, which is non-toxic, non-odour and non pollution; the modifier and film coating possesses excellent hydrophobicity after drying; the product possesses unique water resistance property, ultra-violet rseistance and ageing resistance which the paint do not possess when employing single macromolecular emulsion; and the color can be various according to the requirement; the adhesive strength is strong, the effect of water resistance and impervious is good, possesses the property of heat resistance and freezing resistance and good extensibility; the product can be painted directly and the process is easy, and it is suitable for the water-proof, seepage control and moisture proof for various new and old roofing, basement and toilet and so on.
Description
technical field [0001] The invention belongs to the class of coatings in chemical industry. Specifically, it is a waterproof coating used on buildings. Background technique [0002] At present, there are many varieties of waterproof coatings in my country. There are modified asphalt, polyurethane, acrylic and so on. Modified asphalt waterproof coating is based on asphalt as the main film-forming material, and is modified by adding thermoplastic rubber, waste rubber powder and other polymers. After modification, it overcomes the shortcoming of hot dripping and cold brittleness of asphalt. Poor quality; polyurethane waterproof coating is a reactive waterproof coating composed of isocyanate and polyether as the main raw materials. It contains almost no organic solvent. It is the most widely used waterproof coating in my country and has the best effect. But the cost is high and the price is more expensive; acrylic waterproof coating is prepared by adding polyacrylate as the mai...
