Embodiment Construction

[0008] In order to make the present invention easier to understand, we will describe the present invention in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0009] refer to figure 1 , a high-performance flexible heat-resistant material, which includes PBO staple fiber yarn 2 and stainless steel fiber yarn 1, wherein stainless steel fiber yarn has a count of 5-50Nm and a diameter of 6-50, and PBO staple fiber has a count of 5 ~60Ne, the content of PBO short fiber yarn 2 is 20%~80%, and the content of stainless steel fiber yarn 1 is 80%~20%. During preparation, the stainless steel fiber yarn 1 is first used as the core yarn, and the PBO staple fiber yarn 2 is wound on the stainless steel fiber yarn 1 in a spiral shape to form a covered yarn; then the covered yarn is twisted into two strands; finally, the strand is woven Knitted fabrics, finished products.

[0010] Take the PBO fiber yarn as 45Ne, the stainless steel fiber yarn as 40...

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...
