Abstract
The special concentrated latex of meteorological balloon and meteorological balloon and preparation method are made the invention discloses one kind, the purpose of the present invention is low using calcium ions and magnesium ions content, molecular weight is big and concentrated latex that be evenly distributed makes meteorological balloon, existing concentrated latex is solved in balloon manufacturing process, easily cause covering not ageing-resistant, became uneven, dehydration, adhesive tape, adhesion, the defect such as rubber calcium chloride content is exceeded, decline the qualification rate of balloon, also the physical property of balloon will be influenceed, so as to the molecular weight difference of the component of polymer polyisoprene in the lift-off height and concentrated natural latex that reduce balloon is big, molecular weight distribution is wide, cause the mechanical property difference of latex product big, so as to influence the problem of balloon homogeneity.The present invention is by controlling to make the calcium ions and magnesium ions content in meteorological balloon raw material concentrated latex, the number-average molecular weight of latex and changing meteorological balloon manufacture craft with formula, the performance of meteorological balloon is improve, and then improves meteorological balloon lift-off height, the uniformity of lift-off height and effective percentage.
Description
Technical field：
The present invention relates to a kind of making material for detecting air weather, delivery vehicle and its production method, more particularly to a kind of system
Make the special concentrated latex of meteorological balloon and meteorological balloon and preparation method.
Background technology：
Meteorological balloon is to detect a kind of delivery vehicle that air weather key element is generally used.Being applied not only to meteorological department carries out meteorology
Key element is detected, there is provided meteorological support condition, and is that army performs the national defence scientific researches such as space flight, aviation, navigation, operation and military row
Essential Climate measurement means during dynamic task.In recent years, because industrial development is swift and violent, geographical environment changes greatly, entirely
Ball climate warming, various regions meteorological element there occurs many changes, and it is complicated that meteorological balloon should adapt to be continually changing in atmosphere
Meteorological element.With the development of science and technology, the application of the popularization of novel electron sonde, New Type Radar, to sounding balloon
Lift-off height proposes requirement higher.Level balloon according to detection can be divided into：1. survey wind, survey cloud meteorological balloon,
2. high and medium detects meteorological balloon, 3. aerological sounding meteorological balloon.The need for being developed according to weather service, Sounding Data will
The height for reaching 35000 meters (5hPa) is sought, at present average only 27000 meters or so of detection height, and its effective percentage is relatively low.
During prior art makes meteorological balloon, easily there is covering and has not ageing-resistant, became uneven, dehydration, glue in balloon
The defects such as bar, adhesion, this makes the qualification rate of balloon decline (only 83.64%), and (tensile strength is only for the physical property of influence balloon
For 18.6MPa, elongation are only that 730%), the aging physical property in 10h × 100 DEG C is poor, (tensile strength is only 17.9MPa, elongation
Rate is only 710%, burst diameter only 6.8m) so as to reduce balloon lift-off highly；In addition the poor mechanical property of latex product
It is different big so that between balloon and balloon each several part nature difference is larger, influence the homogeneous performance of meteorological balloon.In process of production
Using the concentrated latex that calcium ions and magnesium ions content is low, molecular weight big and is evenly distributed and substitute new age resistor and limit leaching operation
Soaked temperature and time make meteorological balloon can solve in existing concentrated latex present in manufacturing process and release process
Shortcoming.
