Description

A kind of resistant to elevated temperatures ceramic fibre

Technical field

The present invention relates to a kind of high performance ceramic fibre.

Background technology

Ceramic fibre is a kind of fibrous light refractory material, have lightweight, high temperature resistant, Heat stability is good, thermal conductivity are low, specific heat is little and the advantage such as mechanical resistant vibrations, be thus obtained in the industry such as machinery, metallurgy, chemical industry, electronics and apply widely.Rising steadily in recent years due to global energy price, energy-conservationly become China national strategy, in this context, the ceramic fibre of the energy-conservation 10-30% of reaching such as resistance to material more traditional than insulating brick and pouring material etc. obtains more wider application at China, and development prospect is very good.But existing fiber is comparatively thick, and can not satisfy the demand, along with the progress of technology, the fiber that performance is become better and better will be used gradually.

Summary of the invention

For the deficiencies in the prior art, the technical problem to be solved in the present invention is, provides a kind of high performance ceramic fibre, has good resistant to elevated temperatures performance, and fiber is comparatively thin simultaneously, and performance is better, simultaneously applied range.

For solving the deficiencies in the prior art, the technical scheme that the present invention takes is: a kind of resistant to elevated temperatures ceramic fibre, is made up of the raw material of following parts by weight:

Mineral fibres 8-12 part, magnesia 4-9 part, calgon 5-7 part, fire retardant 3-7 part, dispersant 2-6 part, wheaten starch 6-10 part, FeCl ₃5-9 part, alpha-alumina 8-14 part, talcum powder 2-6 part, antioxidant 1-3 part, silica 9-14 part, dioctyl phthalate 8-11 part, diatom ooze 2-9 part, 3-chloropropyl triethoxysilane 5-9 part, silicone defoaming agent 2-6 part, chloroazotic acid borax 5-10 part, prodan 5-8 part.

The invention has the beneficial effects as follows that high performance ceramic fibre of the present invention has good resistant to elevated temperatures performance, fiber is comparatively thin simultaneously, and performance is better, simultaneously applied range.
