In view of such circumstances, in order to further enhance the heat resistance of silicone rubber, it is well known that metal oxides such as iron oxide and cerium oxide are added to silicone rubber, but the compatibility of metal oxides in silicone rubber systems is poor, Limits the use of silicone rubber adhesives
[0003] Chinese patent CN102643553A discloses a high-temperature-resistant silicone rubber additive and its method. The heat-resistant additive prepared by this method can make the heat-resistant temperature of silicone rubber reach 300°C, but it cannot meet the heat resistance and mechanical properties of silicone rubber under special conditions. Requirements; Chinese patent CN101899214A discloses a heat-resistant additive for silicone rubber and its method. The heat-resistant additive prepared by this method can make the heat-resistant temperature of silicone rubber reach 320°C, but it still cannot meet the heat-resistant and mechanical properties of silicone rubber under special conditions. performance requirements

Abstract

The invention discloses a method for preparing phenanthrene-type (polyphenyl) phenyl polyhedral polyvinylsilicone rubber and relates to a method for preparing silicone rubber. The method comprises that vinyl polyhedral oligomeric silsesquioxane and phenanthroline-type cyclopentadienone undergo a Diels-Alder reaction to produce phenanthrene-type (polyphenyl) phenyl polyhedral polyvinylsilicone oil, and the phenanthrene-type (polyphenyl) phenyl polyhedral polyvinylsilicone oil and silicone rubber undergo a reaction to produce the phenanthrene-type (polyphenyl) phenyl polyhedral polyvinylsilicone rubber. The phenanthrene-type (polyphenyl) phenyl polyhedral polyvinylsilicone rubber has a high conjugation degree condensed ring group and an inserted polyhedral oligomeric silsesquioxane inorganic framework structure and the two structures cooperate. The heat-resistant additive has the high conjugation degree condensed ring group (containing multiple benzene ring groups) and the inserted polyhedral oligomeric silsesquioxane inorganic framework structure and the two structures cooperate so that the thermal stability and mechanical properties of the silicone rubber are greatly improved. The initial decomposition temperature is 460 DEG C, tensile strength is greater than 5Mpa and breaking elongation is 300%.

Description

technical field [0001] The invention relates to a method for preparing silicone rubber, in particular to a method for preparing phenanthrene (polyphenyl) phenyl cage polyvinyl silicone rubber. Background technique [0002] Silicone rubber products are used in high temperature environments due to their excellent heat resistance. Among them, high heat resistance in a higher temperature environment such as a temperature exceeding, for example, 300° C. is required. In view of such circumstances, in order to further enhance the heat resistance of silicone rubber, it is well known that metal oxides such as iron oxide and cerium oxide are added to silicone rubber, but the compatibility of metal oxides in silicone rubber systems is poor, Limit the use of silicone rubber adhesives. [0003] Chinese patent CN102643553A discloses a high-temperature-resistant silicone rubber additive and its method. The heat-resistant additive prepared by this method can make the heat-resistant temper...
