High performance flexibility heat-resisting material and process thereof

Abstract

The invention discloses a high performance flexibility heat-resisting material, comprising PBO staple fibre yarn and stainless steel fibre yarn, wherein, the number of the stainless steel yarn is 5-50Nm and the diameter is 6-50 mu; and the number of PBO fibre yarn is 5-60 Ne, the content of PBO staple fibre yarn is 20% to 80% and the content of stainless steel fibre yarn is 80% to 20%. The preparation process of the material is as follows: firstly taking the stainless steel fibre yarn as the core yarn, and winding the PBO staple fibre yarn spirally on the stainless steel fibre yarn to form cladding yarn; then entwisting the cladding yarn into two threads; and finally weaving the threads into knitting fabric to obtain the finished products. The invention has the beneficial effects of integrating the advantages of PBO fibre and stainless steel fibre, having high strength, high shock resistance, high buffering, high heat resistance and high corrosion resistance, being very flexible, andhaving long service life and low cost.

Description

technical field [0001] The invention relates to a flexible heat-resistant material, in particular to a high-performance flexible heat-resistant material used in the glass manufacturing process and its technology. Background technique [0002] Flexible heat-resistant materials are widely used in various heat-resistant materials in the glass manufacturing process, conveyor belts, heat-resistant cushioning materials in aluminum extrusion molding, and conveyor belts. In the prior art, various heat-resistant fibers are generally used, such as stainless steel fibers, PBO, PBI, aramid, melamine formaldehyde, etc., either alone or in combination. Among them, stainless steel fiber and PBO fiber have the best heat resistance. The stainless steel fiber can be used for a long time at 650°C, the interstitial use temperature is greater than 800°C, the PBO fiber can be used for a long time at 300°C, the interstitial use temperature is greater than 500°C, and the instantaneous use temperat...

AI Technical Summary

Problems solved by technology

At present, the use of stainless steel fibers in the glass manufacturing process cannot meet the quality requirements of high-grade glass. Using PBO fibers alone can meet the requirements, but the service life is short and the cost of use is high.

The performance of PBO and stainless steel fiber interweaving material is between the two, and it cannot fully meet the requirements of high-grade glass.
