Problems solved by technology

Not only good traditional mechanical properties are required, but also requirements for poorer fields are required. While improving strength, the strength of toughness cannot be reduced. It is still difficult to make glass fibers have good mechanical properties and molding properties at the same time.

Abstract

The invention discloses a high-strength and high-temperature-resistant fiber material. The high-strength and high-temperature-resistant fiber material comprises the following raw materials in parts byweight: 550-600 parts of silicon dioxide, 270-300 parts of calcium oxide, 150-200 parts of aluminium oxide, 100-120 parts of magnesium oxide, 80-120 parts of lithium oxide, 10-14 parts of titanium oxide, 30-50 parts of phosphor, 5-10 parts of sodium oxide, 8-12 parts of sulfate, 6-10 parts of iron sesquioxide and 8-12 parts of boron oxide. The high-strength and high-temperature-resistant fiber material comprises the following steps: first step, separately pulverizing the raw materials into particles with the grain size being 50 nm-0.15 mm; second step, mixing the silicon dioxide, the aluminium oxide, the magnesium oxide and the phosphor in advance and heating the mixture to the temperature being 900-1100 DEG C; third step, feeding smashed residual particles into a pre-heating furnace, feeding the pre-heated product into a heating furnace and fusing the pre-heated product at the temperature being 1650-1950 DEG C for 5-7 hours; and fourth step, feeding the fused product into a thread throwing machine to obtain fibers, wherein the revolving speed of a thread throwing roll is 8000-12000 revolutions per part, and the lengths of the fibers are 420 pm-650 pm. The produced fibers are highin mechanical strength, good in chemical stability and good in thermal stability; the acid resistance is improved; and the coefficient of thermal expansion is reduced.

Description

technical field [0001] The invention relates to a high-performance fiber material, in particular to a high-strength and high-temperature-resistant fiber material. Background technique [0002] Glass fiber is an inorganic non-metallic material, which has many advantages such as good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, etc., so it has become the most widely used type of matrix material in reinforced composite materials. With the wide application of inorganic non-metallic materials, the industry's requirements for glass fibers are also increasing. Not only good traditional mechanical properties are required, but also requirements for poorer fields are required. While the strength is increased, the strength of toughness cannot be reduced. The existing technology is still difficult to make glass fibers have good mechanical properties and molding properties at the same time. Therefore, by improving the basic performance of the ...
