Problems solved by technology

[0008] The invention provides a high-strength microcrystalline fiber produced by using tailings and stone waste and its preparation method, which can fundamentally solve the harm to the human body caused by the presence of carbon fibers mainly produced by chemical organic components and inorganic glass fibers that are currently supplied to the domestic market in large quantities. The problem of silicosis health and environmental pollution; solve the problems of existing glass fiber products such as brittleness, poor corrosion resistance, wear resistance, easy fracture, and short service life, and also solve the problem that the natural production raw material source of basalt fiber fluctuates greatly. Difficulties that lead to unstable product quality
At the same time, it can effectively alleviate the environmental problems and hidden dangers of safety accidents caused by the accumulation of tailings and stone waste.

Embodiment 1

[0045] The high-strength microcrystalline fiber produced from tailings has the following raw material composition by weight:

[0046]

[0047] Flame blowing method is the main method of producing microcrystalline fiber, and its process is as follows: when preparing, send the prepared powder into the mixer for homogenization and mixing. The mixed microcrystalline fiber production raw materials are pushed into the electric furnace (or high-temperature fiber melting pool kiln) through a heat-resistant stainless steel screw feeder for high-temperature melting. The melting temperature is 1550°C. The drawing wire flows out from the bottom of the many small holes (800 holes or 1200 holes) of the wire leaking plate to form primary fibers; a single primary fiber with a diameter of 9-15 microns enters the oily infiltrating agent coating equipment, passes through the rotating rubber roller winding machine and the guide Under the guidance of the yarn device, the continuous fiber is wou...

Abstract

A high-strength microcrystalline fiber produced by using tailings waste slag and a preparation method thereof. The raw materials are composed of 28-40 parts by weight of copper tailings, 40-60 parts of basalt stone waste, and 7-60 parts of bauxite tailings. 20 parts, 0.2-1.5 parts of flux and 0.2-0.6 parts of clarifying agent. In its preparation process, the process of "feeding-melting-drawing" is used for production. The present invention uses copper tailings, basalt stone waste, and bauxite tailings as main raw materials, and the products do not burn at a temperature above 750°C, and the cost of production raw materials is reduced by 26-35%. Carbon fiber mainly produced with organic components and inorganic glass fiber are harmful to the health of human silicosis and pollute the environment; solve the problems of brittleness, poor corrosion resistance, wear resistance, easy breakage and short service life of existing glass fiber products , It also solves the problem that the natural production raw material source of basalt fiber fluctuates greatly, resulting in unstable product quality. At the same time, it can effectively alleviate the environmental problems and hidden dangers of safety accidents caused by the accumulation of tailings and stone waste.

Description

technical field [0001] The invention relates to an inorganic fiber-reinforced composite material that is environmentally friendly and energy-saving. A high-strength microcrystalline fiber produced in a mine and a preparation method thereof. Background technique [0002] High-strength microcrystalline fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is composed of tailings and stone wastes composed of oxides such as silica, alumina, calcium oxide, magnesium oxide, iron oxide, and titanium dioxide.
