Abstract

The invention relates to a light-weight flexible irradiation-resistant cover glass which is composed of the following raw materials in percentage by mass: 50.8-62.5% of SiO2, 0.2-0.7% of Al2O3, 10-15.9% of B2O3, 8-10.6% of MgO, 3-6% of Na2O, 11.1-16.4% of Li2O, 0.1-0.5% of K2O, 4.6-5.1% of CeO2 and 0.2-1.6% of P2O5. The preparation method of the light-weight flexible irradiation-resistant cover glass comprises the following steps: A. proportioning; B. charging; C. melting; D. cast forming; E. annealing; F. cutting; G. grinding; H. polishing; I. cleaning; K. drying; and L. low-temperature ion exchange to obtain the light-weight flexible irradiation-resistant cover glass. The light-weight flexible irradiation-resistant cover glass has lighter weight, thereby reducing the take-off weight during satellite launching and lowering the launching cost.

Description

technical field

[0001] The invention belongs to the technical field of supporting products for aerospace equipment, and relates to the field of special glass for space, in particular to a light-weight flexible radiation-resistant glass cover sheet and a preparation method thereof. Background technique

[0002] In the orbital space of the earth, there are radiations such as cosmic rays from the Milky Way, the radiation belts of the earth, and solar particles. When the spacecraft is in space, it is violated by space high-energy particles and rays, and the solar panels on the two wings of the spacecraft will be damaged. wear, causing a short circuit and failure, in order to protect the solar cell, the solar cell is usually covered with a glass cover. Ordinary colorless glass generally does not change its visible light transmission performance when used in a normal environment, but when the glass is used in a space vehicle, it will receive radiation from high-energy particles or...
