Abstract

The invention provides a ceramic filler, which comprises the following components by weight: 10-20 parts of a first oxide, namely a rare metal oxide; 50-70 parts of a second oxide including one or more substance of a light metal oxide, a silicon oxide, an antimony oxide and a transition metal oxide; and 10-30 parts of an oxysalt including one or more substance of carbonate, silicate, metasilicate, borate and phosphate. The ceramic filler contains the rare metal oxide, by adding of the rare metal oxide, the ceramic filler has good tensile strength, elongation at break and tear strength. The experimental results show that, the tensile strength of the ceramic filler is 7.5MPa-8MPa, the elongation at break is 210%-230%, and the tear strength is 20KN / m to 25KN / M.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a ceramic filler. Background technique [0002] Among many synthetic rubbers, silicone rubber is one of the best. Silicone rubber has excellent properties such as good electrical insulation, oxygen resistance and aging resistance, light resistance and aging resistance, mildew resistance, and chemical stability. These excellent properties of silicone rubber make it have important applications in the fields of power transmission lines, aerospace, mechanical parts and electronic appliances. Since silicone rubber is often used under conditions of high pressure, high temperature, heat generation, and discharge, there are high requirements for silicone rubber in terms of flame retardancy. However, after the currently used flame-retardant silicone rubber is continuously burned at high temperature, the burnt residue has no mechanical strength, which may cause more dangerous secondary ...
