The invention relates to the technical field of rubber modification, in particular to a fluororubber-ethylene propylene diene monomer compatilizer and application. Silica (DMSN) with a dendritic mesoporous structure is synthesized and can be physically located at a two-phase interface, the effects of anchoring and reinforcing the phase interface are achieved, the size of a phase region is prevented from being too large, and therefore the compatibility is preliminarily improved. PFTS is further used for carrying out surface grafting modification on DMSN, PFTS is grafted to the surface of silicon dioxide through Si-O-Si, the compatibility of a perfluoro long chain at the other end and an FKM phase is good, and the interface bonding force between the filler and a rubber matrix is remarkably enhanced. The finally obtained composite material not only has the inherent high temperature resistance, oil resistance and chemical resistance of FKM, but also improves the low temperature resistance due to the introduction of EPDM, and greatly enhances the mechanical strength and toughness due to the enhancement of PFTS-DMSN.

A method for preparing a binary formula for Dai pottery clay and its application is disclosed. The method involves taking Dai pottery clay from the Honghe River basin, five-colored clay from Honghe County, and charcoal powder. The Dai pottery clay and five-colored clay are sun-dried and weathered for at least three months. The Dai pottery clay from the Honghe River basin has a SiO2 content of not less than 50%, an Al2O3 content of not less than 15%, an Fe2O3 content of not less than 10%, and a loss on ignition of less than 10%. The five-colored clay from Honghe County has a SiO2 content of 72-82%, an Al2O3 content of 9-12%, and an Fe2O3 content of 3-5%. The method involves soaking the Dai pottery clay and five-colored clay in water until fully saturated, then ball-milling them. The slurry is sieved, and then charcoal powder is added. After stirring evenly, the clay is pressed to drain water and then kneaded to remove air. This invention can improve the throwing and molding performance of Dai pottery clay, increase the sintering temperature and the density and strength of its structure, and reduce the burn-off rate.

The application discloses a knitted belt with elastic covered yarn as floating threads, which comprises a belt body, the belt body comprises a pile layer, a weft layer and a root layer which are connected by integral knitting, the pile layer is located on the surface of the belt body, the weft layer and the root layer are located inside the belt body, and the root layer is arranged between the pile layer and the weft layer, the root layer is connected with the pile layer and the weft layer respectively, and the pile layer is formed on the surface of the belt by knitting with elastic covered yarn in the process mode of floating threads. The pile layer is formed on the belt body by adopting the elastic covered yarn and the process mode of floating threads, so that the problem that the traditional knitted belt cannot consider the hand feeling and the anti-pilling property when pursuing high modulus demand is solved.
