Problems solved by technology

[0004] In the process of making weather balloons in the prior art, the balloon skin is prone to defects such as aging resistance, uneven thickness, dehydration, glue strips, and adhesion, which makes the qualified rate of the balloon drop (only 83.64%) and affects the balloon. Physical properties (tensile strength is only 18.6MPa, elongation is only 730%), 10h × 100 ℃ aging physical properties are poor, (tensile strength is only 17.9MPa, elongation is only 710%, blasting diameter is only 6.8m) to reduce the lift-off height of the balloon; in addition, the mechanical properties of latex products vary greatly, which makes the properties of balloons and various parts of the balloons vary greatly, which affects the uniform performance of weather balloons

Abstract

The invention discloses concentrated latex special for manufacturing of meteorological balloons and a manufacture method of meteorological balloons. The invention aims to adopt concentrated latex with low content of calcium and magnesium ions, large molecular weight and uniform distribution for the manufacturing of meteorological balloons so as to solve the following problems: in the balloon manufacturing process by the use of existing concentrated latex, defects such as no ageing resistance of balloon skin, nonuniform thickness, dehydration, binding bar, adhesion, exceedance of content standards of calcium chloride in rubber and the like are easily caused, qualified rate of the balloons is reduced, physical properties of balloons also will be influenced so as to reduce lift-off height of the balloons, difference in molecular weight of a polymer component polyisoprene in natural concentrated latex is large, molecular weight distribution is wide, difference in mechanical property of a latex product is large, and then uniformity of balloons is influenced. By controlling content of calcium and magnesium ions in the concentrated latex as the raw material for manufacturing of the meteorological balloons and number-average molecular weight of the latex and changing the manufacture process and formula of the meteorological balloons, properties of the meteorological balloons are enhanced and lift-off height of the meteorological balloons and consistency and effective rate of lift-off height are further raised.

Description

Technical field: [0001] The invention relates to a production material for detecting aerial weather, a vehicle and a production method thereof, in particular to a special concentrated latex for making a weather balloon, a weather balloon and a production method. Background technique: [0002] Meteorological balloons are a vehicle commonly used to detect meteorological elements in the air. It is not only used by meteorological departments to detect meteorological elements and provide meteorological support conditions, but also is an indispensable meteorological test method for troops to perform national defense scientific research and military operations such as aerospace, aviation, navigation, and combat. In recent years, due to the rapid development of industry, great changes in the geographical environment, and global warming, many changes have taken place in meteorological elements in various places. Weather balloons should adapt to the changing and complex meteorological...
