2results about How to "Rain-resistant" patented technology

The application provides a spraying agent for preventing and treating snails and a preparation method and application thereof, and belongs to the technical field of pesticides. The spraying agent comprises ginkgo leaf extract, psoralea corylifolia fruit extract, bloodgrass extract, modified chitosan, hydroxypropyl-beta-cyclodextrin, tetrahydro-piperine, eucalyptol, polyvinyl alcohol, surfactant, dispersant and water. The spraying agent has both contact killing and stomach poisoning effects by using three plant source extracts as snail killing active ingredients. Tetrahydro-piperine and eucalyptol are compounded as penetration enhancers, which can effectively open the snail body surface channel, improve the penetration rate and bioavailability. The modified chitosan and polyvinyl alcohol form a water-resistant film skeleton, and the inclusion protection of hydroxypropyl-beta-cyclodextrin, so that the spraying agent forms a water-resistant protective film on the surface of plants or buildings. The spraying agent has the advantages of high efficiency, rainwater resistance, long persistence and the like, and can be widely applied to the prevention and treatment of snails on the surfaces of crops, flowers, lawns and buildings.

The invention relates to the technical field of paint, in particular to water-based wind turbine blade finish paint and a preparation method thereof. The water-based wind power blade finish paint comprises a component A and a component B, wherein the component A comprises water, a coalescing agent, a dispersing agent, a first defoaming agent, a water-based rheological agent, titanium dioxide, a wear-resistant filler, a water-based hydroxyl acrylic emulsion, a water-based polyurethane dispersion, a wax emulsion, a second defoaming agent and a base material wetting dispersing agent; and the component B comprises a water-based isocyanate curing agent and propylene glycol diacetate. The finish paint provided by the invention is high-performance environment-friendly water-based wind power blade finish paint, has the characteristics of high drying rate, smooth roller painting construction and the like, and is excellent in construction performance; meanwhile, the coating has low VOCs content, also has excellent mechanical properties, medium resistance, ultraviolet aging resistance, salt mist resistance, damp heat resistance, high and low temperature resistance, weather alternation resistance, wear resistance, rain erosion resistance, icing resistance, mold resistance and other protection properties, and can meet the long-acting protection requirements of wind turbine blades.
