Heat-insulating, waterproof and environment-friendly paint and preparation method thereof

Abstract

The invention discloses heat-insulating, waterproof and environment-friendly paint and a preparation method thereof. The heat-insulating, waterproof and environment-friendly paint is prepared by adding a porous inorganic material into acrylic emulsion, and combining pigments, auxiliaries and a lotus effect self-cleaning agent. The heat-insulating, waterproof and environment-friendly paint has very good solar reflecting ability and extensibility, has a reflecting rate of 86% on sunlight, has radiance of 0.88, has absorbing ability of 99.9% on ultraviolet light, and can effectively inhibit the temperature of a coated object from quickly increasing under the irradiation of sunshine. In hot summer, the heat-insulating, waterproof and environment-friendly paint can effectively isolate solar radiant heat, so that the working time of an air conditioner is reduced, and energy resources are saved. Besides, the solid content of the paint exceeds 65%, and the paint is high in covering power, has good extensibility and waterproof function, and is guaranteed to be not cracked while used on the surface of an object with fierce temperature variation and obvious expansion and concentration, so that good waterproof rust-proof protection is provided for equipment, a pipeline, a storage tank and the like. The paint is rich in color and long in service life, and not only provides a remarkable energy-saving effect, but also achieves the effect of beautifying a building.

Description

technical field [0001] The invention relates to a heat-insulating, waterproof and environment-friendly coating and a preparation method thereof, which is especially suitable for the surfaces of petroleum and petrochemical storage tanks, tank trucks and civil buildings. Background technique [0002] With the continuous development of the global economy, the demand for energy in human society is increasing year by year; while our country is in a stage of rapid economic development, the consumption of energy is increasing, and the growth rate is higher than the world average growth rate. According to reports, my country has surpassed the United States to become the world's largest energy consumer since 2010. In 2012, the consumption of primary energy reached 2,735 million tons of oil equivalent, accounting for 21.9% of the world's energy consumption; therefore, how to use energy more reasonably , saving energy has become one of the important prerequisites for our country to achi...

AI Technical Summary

Problems solved by technology

At present, countries such as Europe and the United States have developed several high-performance thermal insulation coatings, but the main defect is that they are all oil-based coatings, which contain a large amount of harmful gases, which will cause harm to the human body and the environment during use.

The research and development of domestic thermal insulation coatings is also very immature, and there are generally problems of single function and high cost

At present, domestic enterprises mainly rely on imported products from abroad, not only with high unit prices, but also subject to human
