Description

Technical Field

[0001] The utility model belongs to the technical field of drip-free membranes, in particular to a fog-eliminating, waterproof, breathable and drip-free membrane. Background Art

[0002] The drip-free film has a special anti-fog plastic additive added to the formula, which can make the water vapor near the film adsorb to the film surface to form a water film that drips downward, thereby preventing and eliminating fog and reducing the relative humidity of the air.

[0003] However, in some usage environments, the membrane needs to have waterproof and breathable functions. The waterproof and breathable membrane achieves waterproof and breathable functions through the principle of the difference in molecular distance between air and water vapor. It is difficult to produce a drip-free membrane with waterproof and breathable functions through formula modification or production process modification, and there will be more or less problems of poor and unstable effects. Summary of the invention

[0004] The utility model aims to provide a defogging, waterproof, breathable and drip-free membrane. By arranging a drip-free membrane and a waterproof and breathable membrane at intervals on the inner side of an integral base membrane, the drip-free membrane plays a role in preventing and eliminating fog, and the waterproof and breathable membrane plays a role in waterproofing and ventilation. It has efficient defogging and ventilation capabilities, and the various properties will not affect each other. At the same time, the three are connected by a heat sealing strip, which is convenient for connection and production.
