Embodiment 1

[0045] Prepare the required raw materials and prepare the ingredients according to the following parts by weight: 23 parts of basalt, 6.5 parts of boronite, 36 parts of pyrophyllite, 14 parts of quicklime, 14 parts of quartz powder, 4 parts of ferric oxide, and 2.5 parts of titanium dioxide. The raw materials are mixed into a batch, and mixed 18 times in a mixing tank with a pressure of 300kPa to obtain a uniform batch. The uniform batch is sent to a 1320°C pool kiln through a kiln head silo and a screw feeder for melting, clarification and homogenization to obtain a black The molten glass, and then the molten glass flows out and enters the main passage at 1270°C, the distribution passage at 1210°C, the working passage at 1150°C, and then enters the platinum-rhodium alloy leakage plate with a leak nozzle at the bottom through the flow tank. The diameter of the molten glass is 1.5- The 2mm nozzle flows out to obtain liquid black glass filaments. The length of the liquid glass fi...

Abstract

The invention provides black glass fiber and a preparation method thereof. The black glass fiber prepared by virtue of the preparation method contains SiO2, Al2O3, CaO, MgO, B2O3, Fe2O3, TiO2, MnO2 and K2O+Na2O. The black glass fiber is prepared through direct wiredrawing in a preparation process, and secondary dip dyeing is omitted, so that the problems in the prior art that the dyeing is not uniform, the dyeing adhesive force is poor and the fiber is easy to fall in a secondary dip dyeing process are solved. The preparation method provided by the invention has the beneficial effects that the prepared black glass fiber is low in melting temperature and high in acid-base resistance, and the main raw material is basalt which is widely distributed, high in reserve and low in cost, so that the production cost is greatly lowered.

Description

technical field [0001] The invention relates to the field of electronic non-metallic materials, in particular to a black glass fiber and a preparation method thereof. Background technique [0002] At present, engineering plastics and magnesium-aluminum alloys, which are widely used in electronic products, have problems such as heavy weight, poor thermal conductivity, high cost, not strong, and not wear-resistant. The most common method to change the above disadvantages at this stage is to use carbon fiber As a reinforcing material, carbon fiber is expensive, and it is not easy to form and color during the production process. Moreover, carbon fiber has strong conductivity, and electronic products using carbon fiber are prone to leakage. [0003] Glass fiber is an inorganic non-metallic material with excellent performance. It has excellent insulation, heat resistance, corrosion resistance, and has the advantages of high mechanical strength and high modulus. Therefore, in recen...
