The present application relates to the technical field of high molecular antifogging
coating, and particularly relates to a supermolecular coated shed film antifogging
coating solution, a preparation method and application thereof, wherein
acrylic acid, acrylamidoalkyl
sulfonic acid, hydroxyalkyl
acrylate and double-ene crosslinking
monomer are used for
tetra-copolymerization to construct a supermolecular matrix with carboxyl,
sulfonic acid group, hydroxyl side group and crosslinking network, and a spandex antifogging agent is introduced in situ in the matrix,
hydrogen bond and hydrophobic association synergistic effect between the side group functional groups and the spandex molecules are used to realize supermolecular
coating, and then pH adjustment and functional additive compounding are performed to obtain the coating solution. The present application solves the problems of easy migration and
precipitation of the traditional antifogging agent, coating
brittleness, short effective period, and the obtained coating has comprehensive performances of long-acting antifogging, high
light transmission, strong adhesion, flexible and bending-resistant, water-resistant and aging-resistant, and
room temperature rapid curing, and is suitable for antifogging treatment of various agricultural shed films and
greenhouse transparent materials.
