Abstract

The invention provides a screen protection layer and a production method thereof. The screen protection layer is mainly produced from a magnesium aluminate spinel composite material, an organic solvent and a binder; the magnesium aluminate spinel composite material comprises magnesium aluminate spinel and an additive, and the mass of the additive is 0.8-11% of the mass of the magnesium aluminate spinel composite material; a mass ratio of the organic solvent to the magnesium aluminate spinel composite material is 1:(1-6); and a mass ratio of the binder to the magnesium aluminate spinel composite material is (0.3-3):100 The method comprises the following steps: grinding, granulating, compacting to form a blank, degreasing, pre-sintering, and sintering. The screen protection layer has high light transmittance, and has no scratches under strict use conditions, and the thickness reduces by above 60% under a same protection requirement, so the weight is effectively reduced; and the protection ability is improved under a same thickness.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a magnesium aluminum spinel screen protective layer and a preparation method thereof. Background technique [0002] With the development of modern technology, more and more smart electronic products have entered people's lives and become an indispensable part of people's lives. For example, smart phones, tablet computers, smart watches, etc., the display screens of these smart electronic products are covered with a protective layer. [0003] The existing protective layer often produces scratches during use, which affects the display effect of the screen. At the same time, the thickness of the existing protective layer is relatively thick, so that smart electronic products cannot meet the requirements of thinness and lightness, which affects their sense of use. [0004] In view of this, this invention is proposed. Contents of the invention [0005] The first object of the ...
