Abstract

The invention discloses a glass fiber produced by using waste glass as a raw material and a preparation method thereof, and particularly relates to the technical field of the recycling of glass. The glass fiber is prepared from the following raw materials in parts by weight: 30 to 50 parts of the waste glass, 10 to 15 parts of quartz sand, 10 to 12 parts of sodium sulfate, 5 to 10 parts of calcite, 5 to 12 parts of zircon sand and 2 to 20 parts of sodium carbonate. The preparation method comprises the following steps of (1), pretreatment of the waste glass; (2), confecting of a mixed material;(3), melting; (4), clarification and preparation of the glass fiber. According to the preparation method, the glass fiber is produced by using the waste glass as the raw material; not only can adverse influences generated by the waste glass to an environment be reduced, but also a resource can be recycle; favorable economic and social benefits are obtained; moreover, the preparation method is simple, and the popularization and the application are suitable.

Description

technical field [0001] The invention relates to the field of waste glass recycling, in particular to a glass fiber produced from waste glass as a raw material and a preparation method thereof. Background technique [0002] Glass is a substance commonly used in modern human life, and can be made into utensils, utensils and flat glass. As a result, there are also many wastes. In China, more than 12 million tons of waste and broken glass are not used in scientific and high-end recycled products every year. The general processing mode is to make low-grade, low-value glass products. What's more, the waste glass is directly stacked in the open air or buried deep, occupying a large amount of arable land, which not only seriously pollutes the environment, but also wastes precious resources. From an economic and environmental point of view, the best way is to recycle waste glass. [0003] Therefore, how to achieve it and make reasonable and efficient utilization of waste glass res...
