Preparation method of SiC microwire modified gypsum
The invention relates to a preparation method of SiC microwire modified gypsum. The method includes the following steps of firstly, adding SiC microwires to hydrogen peroxide to be soaked and dried in the air for standby application; secondly, preparing a SiC microwire mixture A; thirdly, preparing a SiC microwire mixture B; fourthly, adding gypsum powder to the SiC microwire mixture A to obtain a mixture C; fifthly, pouring half of the mixture C into a forming die, and conducting drying to obtain a sample D; sixthly, soaking carbon fiber cloth in phenolic resin, and flat laying the carbon fiber cloth on the upper surface of the sample D to obtain a sample E; seventhly, coating the upper surface of the sample E with at least one layer of SiC microwire mixture B, and drying the mixture B to obtain a sample F; eighthly, pouring the rest of the mixture C on the upper surface of the sample F, and conducting drying and demolding to obtain SiC microwire modified gypsum. The breaking strength of the modified gypsum obtained through the preparation method is improved by 200-350%.
