Silica gel key processing technology capable of adjusting light transmittance

Abstract

The invention discloses a light transmittance adjustable silica gel key processing technology which comprises the following steps: S1, preparing a mold: manufacturing a corresponding silica gel key mold according to a drawing or a sample of a silica gel key, performing clearance treatment on the back surface of a corresponding position of the key according to the requirement that the key needs laser etching and light transmission, and after the silica gel key mold is manufactured, manufacturing the silica gel key mold into a mold; and the silica gel keys are trial-manufactured in small batches so as to ensure that the silica gel key mold is qualified. According to the technical scheme, the back face of the corresponding position of the key is subjected to clearance treatment according to the requirement that the key needs laser etching light transmission, then the silica gel with the corresponding color is prepared according to the requirement for forming production, and therefore the light transmission effect is achieved, and when the silica gel before production is subjected to color matching according to the experience, the thickness of the light transmission position of the back glue of the key is 1-2 mm, and the thickness of the light transmission position is 1-2 mm. When the proportion of the added white color glue is increased by 5%, the thickness of the light-transmitting part of the back glue of the key is reduced by 0.5 mm, but the thinnest is not less than 0.1 mm, and the thickest is not more than 2 mm, so that the adjustability of the light transmittance of the silica gel key is realized.

Description

technical field [0001] The invention relates to the technical field of light-permeable silicone keypads, and more specifically, the invention relates to a process for processing silicone keypads with adjustable light transmittance. Background technique [0002] Silica gel alias: silicic acid gel, is a highly active adsorption material, which is an amorphous substance. The main component of silica gel is silicon dioxide, which is chemically stable and non-combustible. Its chemical molecular formula is mSiO2 nH2O, which is insoluble in water and Any solvent, non-toxic and tasteless, does not react with any substance except strong alkali and hydrofluoric acid; and different types of silica gel form different microporous structures due to different manufacturing methods, so the chemical composition and physical structure of silica gel, It has determined that it has many characteristics that other similar materials are difficult to replace: such as high adsorption performance, go...
