Problems solved by technology

[0003] At present, the storage time of water-based saturated polyester resin dispersion emulsion is generally between 6 months and 12 months, and the storage time is generally not long, which leads to the need to use water-based saturated polyester resin dispersion emulsion as soon as possible after production. The effect of the elapsed emulsion gradually decreases, which leads to the strict control of the demand for the material by the manufacturers and users, which increases the management and control costs of the enterprise. At the same time, the requirements for the transportation of the material are also high. As a chemical raw material, its transportation requirements lead to the Increased production or use costs

Abstract

The invention discloses waterborne saturated polyester resin dispersion emulsion and a preparation method thereof. The waterborne saturated polyester resin dispersion emulsion is prepared from the following raw materials in parts by weight: 50 to 60 parts of saturated polyester resin, 0.5 to 2.5 parts of non-ionic emulsifier, 0.5 to 2.5 parts of anion emulsifier and 40 to 50 parts of deionized water. The waterborne saturated polyester resin dispersion emulsion disclosed by the invention has the beneficial effects of extremely-low content of VOC (Volatile Organic Compounds), good dispersion effects and long storage time.

Description

technical field [0001] The invention relates to a dispersion emulsion and a preparation method thereof, in particular to a water-based saturated polyester resin dispersion emulsion and a preparation method thereof. Background technique [0002] As a landmark industry in modern society, the automobile industry has become a pillar industry of the national economy with the rapid development of China's economy. However, its negative impact on the environment is further highlighted. Now the domestic automobile industry generally uses low-solid solvent-based coatings for vehicle painting. The production and construction of solvent-based coatings will inevitably emit a large amount of organic compounds (VOC) and hazardous air pollutants (HAPS), which will seriously endanger human health and cause environmental pollution. Therefore, in 2010, the national standard GB24409-2009 "Limits of Hazardous Substances in Automobile Coatings" also strictly limited the emission of VOCs in autom...
