Abstract

The invention discloses a platinum compound with a fikarest configuration as well as a preparation method and application of the platinum compound. The invention provides a platinum compound with a fikaster configuration. The platinum compound is Pt-(P-(O-R1) (O-R2) (O-R3)) n. The platinum compound with the non-caster configuration has the characteristics that the platinum compound is not cured for more than 1.5 months at the temperature of 30 + / -5 DEG C and can be rapidly cured for a short time at the temperature of more than 140 DEG C, and particularly, any inhibitor does not need to be added when silica gel base materials are vinyl silicone oil and hydrogen-containing silicone oil, so that the platinum compound is particularly suitable for production and use of various single-component addition type silica gel.

Description

technical field [0001] The present invention relates to a non-caster configuration platinum compound, its preparation method and its application. Background technique [0002] Addition silicone is a silicone material that is widely used in electronic potting, dental materials, medical cosmetic materials and high-end adhesives; and Castel platinum catalyst is currently the dominant curing agent in the production of addition silicone; it Also known as platinum water, platinum catalyst or K-type platinum catalyst, Custer is the name of an engineer working for Dow Corning in the United States. He invented this type of catalyst in the 1970s; the catalyst has high activity and is compatible with silicone Good performance, but the disadvantage is that the curing speed is too fast at room temperature, because it is generally necessary to use it with an inhibitor to make a one-component or two-component silicone product for application; the combination with the inhibitor requires a l...
