Abstract

The invention relates to the technical field of refractory fiber materials, and discloses a 1260 DEG C biosoluble environment-friendly refractory fiber and a preparation process thereof. The refractory fiber is prepared from, by mass, 67.6-70.32% of SiO2, 13.34-15.37% of CaO, 8.48-11.26% of MgO and 3.28-5.57% of ZrO2, and the content of impurities in the refractory fiber is not higher than 2%. Thepreparation process of the refractory fiber comprises the following steps: 1) mixing of materials; 2) material distribution; 3) melting; 4) spinning to form fibers; 5) collecting of cotton; and (6) post-treatment, cutting, and rolling to obtain the refractory fiber product. On the basis of the original 1200 DEG C soluble environment-friendly fiber, by adding a proper amount of high-melting-pointzirconium oxide, the high-temperature crystallization speed of the fiber is successfully reduced, the service life of the refractory fiber is effectively prolonged, and meanwhile, the fiber meets therequirement that the alkaline earth metal content of C3 type fibers and biosoluble environment-friendly refractory fibers is 18-43%.

Description

technical field [0001] The invention relates to the technical field of refractory fiber materials, in particular to a 1260°C bio-soluble environment-friendly refractory fiber and a preparation process thereof. Background technique [0002] The European Union divides man-made fibers into three categories, namely C1, C2, and C3: [0003] C1: determined to cause human cancer, such as asbestos; [0004] C2: May cause cancer, such as traditional mineral fibers (rock wool, mineral wool), glass fibers, aluminum silicate ceramic fibers, etc.; [0005] C3: There is not enough evidence to show that it causes human cancer, such as bio-soluble fiber, also known as alkaline earth silicate fiber, the content of alkaline earth metal in the chemical composition of this type of fiber is 18%-43%, that is, this type of fiber can pass through after being inhaled into the human body Human body fluids are degraded and excreted after a certain period of time, and will not affect the human respir...
