Abstract
The invention discloses a kind of dedicated concentrated latex of production meteorological balloon and meteorological balloon and production methods, the purpose of the present invention is low using calcium ions and magnesium ions content, molecular weight is big and the concentrated latex production meteorological balloon that is evenly distributed, existing concentrated latex is solved in balloon manufacturing process, easily cause covering not ageing-resistant, became uneven, dehydration, adhesive tape, adhesion, the defects of rubber calcium chloride content is exceeded, decline the qualification rate of balloon, also it will affect the physical property of balloon, to reduce balloon lift-off height and the component of polymer polyisoprene in concentrated natural latex molecular weight difference it is big, molecular weight distribution is wide, cause the mechanical property difference of latex product big, the problem of to influence balloon homogeneity.This patent passes through calcium ions and magnesium ions content, the number-average molecular weight of latex and the change meteorological balloon manufacture craft and formula in control production meteorological balloon raw material concentrated latex, the performance of meteorological balloon is improved, and then improves meteorological balloon lift-off height, lift-off high consistency and effective percentage.
Description
Technical field:
The present invention relates to a kind of making material, delivery vehicle and its production methods more particularly to one for detecting air weather
The dedicated concentrated latex of kind production meteorological balloon and meteorological balloon and production method.
Background technique:
Meteorological balloon is a kind of delivery vehicle for detecting air weather element and generalling use.It is applied not only to meteorological department's progress
Meteorological element detection, provides meteorological support condition, and is that army executes national defence scientific researches and the armies such as space flight, aviation, navigation, operation
Essential Climate measurement means when thing action task.In recent years, since industrial development is swift and violent, geographical environment variation
Greatly, many variations have occurred in global warming, various regions meteorological element, and meteorological balloon should adapt to continually changing multiple in atmosphere
Miscellaneous meteorological element.With the development of science and technology, the application of the universal of novel electron sonde, New Type Radar, to sounding gas
More stringent requirements are proposed for the lift-off height of ball.It can be divided into according to the level balloon of detection: 1. survey wind, survey cloud meteorological balloon,
2. high and medium detects meteorological balloon, 3. aerological sounding meteorological balloon.According to the needs that weather service develops, sounding money
Material requires the height for reaching 35000 meters (5hPa), and detection height averagely only has 27000 meters or so at present, and its effective percentage is lower.
During the prior art makes meteorological balloon, covering, which easily occurs, in balloon to be had not ageing-resistant, became uneven, takes off
The defects of water, adhesive tape, adhesion, this makes the qualification rate of balloon decline (only 83.64%), and the physical property for influencing balloon (stretches
It is only that 730%), 10h × 100 DEG C aging physical property is poor that intensity, which is only 18.6MPa, elongation, and (tensile strength is only
17.9MPa, elongation are only that 710%, burst diameter is only 6.8m) to reduce the lift-off height of balloon；Furthermore latex product
Mechanical property difference it is big so that influencing the uniform performance of meteorological balloon between balloon and balloon each section nature difference is larger.
In process of production using the concentrated latex that calcium ions and magnesium ions content is low, molecular weight is big and is evenly distributed and substitute novel anti-aging agent and
The soaked temperature and time production meteorological balloon for limiting leaching process can solve in existing concentrated latex in manufacturing process and release
The shortcomings that existing in the process.
Summary of the invention:
The purpose of the present invention is to provide a kind of dedicated concentrated latex of production meteorological balloon and meteorological balloon and production methods.
The number-average molecular weight and meteorology for the calcium ions and magnesium ions content and latex in concentrated latex that this patent passes through control production meteorological balloon
