Preparation method of low-carbon light reflecting energy-saving coating

Abstract

The invention discloses a preparation method of a low-carbon light reflecting energy-saving coating. The method comprises the following steps of: modifying various pigments-fillers by using a chelate titanate coupling agent; adding an aid and water into the pigments and fillers, and grinding the pigments and fillers into slurry; and adding a base material into the slurry for blending into the coating. The reflectivity of the coating obtained by the method is increased to 85-90 percent, and the content of VOC (Volatile Organic Compound) is greatly lowered.

Description

technical field [0001] The invention relates to water-based coatings, in particular to low-carbon environmental protection reflective light energy-saving coatings. Background technique [0002] With the rapid development of my country's construction industry, building energy consumption has also increased accordingly. In recent years, the energy consumption of residential buildings in the country has accounted for 12.6% of the total energy consumption in the country when there is basically no hot water supply. In some severe cold regions, urban building energy consumption is as high as about 50% of local energy consumption. The Ministry of Construction has proposed that "by 2010, the total energy consumption of urban buildings in the country should basically achieve 50% energy saving, and by 2020, the northern and coastal economically developed regions and megacities should achieve the goal of 65% building energy saving." This will bring huge business opportunities to the l...

Problems solved by technology

However, the above-mentioned various methods are still not perfect in polymerization technology and process, such as the control of the ratio of soft and hard monomers, the control of molecular weight and molecular weight distribution, etc. directly affect the T of the polymer. Kg and MFT are two important parameters, which affect the film-forming characteristics and comprehensive mechanical properties of the coating

At present, there are few types of high-boiling film-forming additives used in water-based coatings, and the compatibility research with other additives-defoamers, wetting agents, dispersants and other additives has not been reported. In terms of industrial production and market Coatings are in the transition phase to zero-VOC products
