Abstract
The invention relates to a sun burn-resistant coating material in a drip irrigation zone. The material is prepared by mixing a fluorinated acrylate copolymer and benzophenone according to an equivalence ratio of 1:(0.02-0.04), wherein the fluorinated acrylate copolymer is prepared by the following steps: mixing 1 part by equivalent weight of octadecyl acrylate and acrylic acid-2-hydroxyethyl acrylate, and adding an initiator azodiisobutyronitrile for carrying out a polymerization reaction, thus obtaining an acrylate copolymer intermediate A with lots of hydroxyl groups on a side chain; slowly dropwise adding the intermediate A into a solution of 1,6-hexamethylene diisocyanate while stirring, thus obtaining an acrylate copolymer intermediate B with lots of isocyanate groups on a side chain after reaction; adding fluorine alcohol into the intermediate B, thus obtaining an acrylate copolymer intermediate C with lots of fluorocarbon chains on a side chain after reaction; and finally, adding ethanol into the intermediate C for carrying out a blocking reaction, thus obtaining the fluorinated acrylate copolymer. Meanwhile, the invention also provides a method for using the coating material. The coating material is low in cost and has an obvious effect.
