Problems solved by technology

[0004] The Chinese patent with the publication number CN102508320A discloses a high-altitude balloon with a waterproof protective layer and a processing method. The method improves the weather detection by coating an oil coating on the outer surface of the existing weather detection balloon. The waterproof performance of air balloons can improve the release height of weather balloons in rainy and humid weather environments, but there are the following disadvantages: oils will be absorbed by the balloons, on the one hand, the weight of the balloon itself will increase, and the payload will decrease. The lift-off height is extremely unfavorable. On the other hand, after the material is absorbed by the balloon, it will also adversely affect the physical and mechanical properties of the balloon, such as stretching, blasting and anti-aging performance. The treated balloon can be released immediately, if after a certain period of time After storage and release, the release height not only cannot reach the expected height, but is worse than that of untreated balloons; in addition, the hydrophobicity of the coating is limited, and the operation is cumbersome and the practicability is limited

Abstract

The invention relates to a waterproof weather balloon and a production method. The weather balloon comprises a balloon matrix and a hydrophobic film coated on a balloon matrix surface. The hydrophobicfilm comprises 8.5-11.5 parts of a hydrophobic main agent, 1-3 parts of a solubilizer, 0.1-0.3 parts of an organic film forming agent and 85.2-90.4 parts of water. The hydrophobic main agent is a compound of one or more of an organosilicon hydrophobic agent and an organic fluorine hydrophobic agent. In the weather balloon, a synthetic material possessing a hydrophobic function is used; and through a necessary operation, a layer of molecular film and even a nanometer film which can achieve a hydrophobic effect are manufactured on a balloon surface. After the balloon is casted and encounters water, beads are formed and are rapidly dispersed and drained so that a problem that the weather balloon which is casted on a rainy day or in humid weather carries out embrittlement acceleration and isblasted in advance due to accumulation of ice on the surface because of surface water absorption so that a service height requirement can not be satisfied is solved.

Description

technical field [0001] The invention relates to a vehicle for detecting air weather and a production method thereof, in particular to a waterproof weather balloon and a production method thereof. Background technique [0002] Meteorological balloons are the most convenient and economical vehicles for carrying sounding instruments to detect air meteorological elements (temperature, humidity, wind direction, wind force, air pressure, etc.), and are widely used in aviation, aerospace, navigation, combat and military scientific research and other fields. . [0003] Weather balloons made of natural rubber latex are water-absorbent. After the balloon absorbs water, the ball skin swells, and the water absorption rate is about 20%. When the balloon is released in rainy weather, in addition to the increase in load, the decrease in payload and the decrease in speed-up, it is even more unfavorable that the water droplets in the atmosphere encountered during the flight will be absorbed...
