Embodiment 1

[0015] In a four-neck flask with a reflux condenser, a thermometer, a stirrer and a dropping funnel, add 70 grams of isopropanol and start the stirrer to stir. When the temperature rises to 70-85°C, after the solvent isopropanol is refluxed in the condensation tube, start to drop 70 grams of isopropanol, 2.5 grams of dodecafluoroheptyl methacrylate, 210 grams of butyl acrylate, 27 grams of The mixture of acrylic acid, 1.74 grams of azobisisobutyronitrile and 32 grams of hydroxypropyl acrylate was added dropwise after 2 hours, and then the temperature was kept at 70-85°C to continue stirring for 2 hours; The mixture of azobisisobutyronitrile was added for 10 minutes, then stirring was continued for 2 h keeping the temperature at 70-85°C. After the heat preservation is over, adjust the solid content to 60±2%, take out the product, and seal the can for packaging.

Abstract

The invention discloses a fluorine-containing acrylate leveling agent for an environment-friendly type water-soluble coating and a preparation method thereof. The acid value of the leveling agent is 30-60; the number-average molecular weight of the leveling agent is 3500-4500; the weight-average molecular weight of the leveling agent is 5000-10000; and the polydispersity of the leveling agent is 1.7-3.0. The invention aims at providing the fluorine-containing acrylate leveling agent for the environment-friendly type water-soluble coating, which can reduce the surface tension of a coating system, and has the advantages of high leveling speed, strong anti-shrinkage capacity and excellent long-wave leveling.

Description

technical field [0001] The invention relates to a fluorine-containing acrylate leveling agent for water-soluble paint, which belongs to the technical field of paint additives. Background technique [0002] The national climate change plan is an important national-level special plan in the "Twelfth Five-Year Plan". Solventborne industrial coatings are increasingly restricted in application due to their VOC emissions. However, the current non-silicon leveling agents used in water-soluble industrial coatings have disadvantages such as high surface tension, slow leveling speed, poor anti-shrinkage cratering ability and poor long-wave leveling. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly fluorine-containing acrylate leveling agent for water-soluble coatings, which can reduce the surface tension of the coating system, has fast leveling speed, strong anti-shrinkage ability and excellent long-wave leveling. [0004...
