Abstract
The invention relates to external coating liquid for an agricultural greenhouse film, which comprises 87 to 95 parts of purified water, 4.5 to 8.5 parts of aluminum sol, 0.1 to 2 parts of aqueous acrylic emulsion, 0.1 to 1 part of aqueous defoaming agent, 0.5 to 1.5 parts of flatting agent, 0.1 to 0.5 part of propylene epoxide and 2.0 to 4.5 parts of O/W type non-ionic surfactant. After a greenhouse film of polyolefin for agricultural use is coated with the external coating liquid disclosed by the invention, a layer of interface with excellent hydrophilic performance is formed at the surface of the greenhouse film. The surface tension of the interface approaches to that of water, so that the water can be spread into a water film so as to act as the action of defogging flow drops. By trial, the average flow drop defogging period of the greenhouse film reaches more than three years, and the aim of synchronizing with the service life of aging of a thin film is achieved. Resources are saved, and the use cost is also lowered.
Description
Technical field
