Problems solved by technology

Plastic optical fiber has strong corrosion resistance and low cost, but its light guide is poor, especially after long-term use, its light transmission will further deteriorate due to its aging
Although glass optical fiber has excellent light guiding performance, the main component of glass optical fiber is SiO2, which is easily corroded by OH- generated by hydration

Abstract

The invention relates to a glass optical fiber surface treating agent, an alkali-resistant glass optical fiber and a light-transmitting concrete prefabricated part, and belongs to the technical fieldof concrete. The glass optical fiber surface treating agent is prepared from the following components in parts by weight: 100 parts of ethylene vinyl acetate copolymer emulsion, 5 to 9 parts of a silane coupling agent, 4 to 6 parts of a film-forming agent, 8 to 10 parts of a surfactant and 150 to 200 parts of deionized water. The glass optical fiber surface treating agent can improve the alkali resistance of the glass optical fiber, and the durability of concrete can be improved when the treated glass optical fiber is applied to the concrete.

Description

technical field [0001] The invention belongs to the technical field of concrete, and relates to a glass optical fiber surface treatment agent, an alkali-resistant glass optical fiber and a light-transmitting concrete prefabricated part. Background technique [0002] The impression of traditional concrete is always very dark. With the vigorous development of civil engineering construction, civil construction workers are also trying to use more methods to change the dark and gray perception of concrete. Light-transmitting concrete first originated in Hungary in 2001. An architect implanted optical fibers and some materials into traditional concrete. Through these optical fibers, one end of the light is transmitted to the other end, so that a clear outline can be seen at the other end. The effect is like a screen or scanning machine, which can well improve the traditional thick and dark feeling of concrete. [0003] From the emergence to the use of light-transmitting concrete,...
