Organic silicon product surface oil-seal method

Abstract

The invention discloses an organic silicon product surface oil-seal method which is characterized by comprising the steps as follows: preparing liquid silicone rubber mixing solution, coating, heating and naturally cooling, wherein the liquid silicone rubber mixing solution comprises the components in percent by volume: 5 to 20 percent of vinyl silicone oil, 10 to 20 percent of hydrogen-containing silicone oil and 0.5 to 5.5 percent of platinum catalyst; the heating temperature ranges from 80 to 200 DEG C; and the heating time is 5 to 25 min. The method has the benefits that the reaction condition is mild, the implementation is easy, the operation is convenient, the environmental pollution is reduced, the wastes of manpower and energy sources are reduced, the health of operators is not jeopardized, and meanwhile, the product prepared by the method still keeps the relatively dry and oil-free appearance after being put for a long time, and the oil-seal effect is remarkable.

Description

technical field [0001] The invention relates to a method for improving the surface of organic silicon series products, in particular to a method for preventing oil seepage and oil discharge from the surface of organic silicon series products. Background technique [0002] During the manufacturing process of some silicone series products, or after the product is vulcanized, with the storage status of the product itself and the change of the storage environment, such as temperature, humidity, pressure changes, etc., there will be oil leakage and oil leakage on the surface of the product. The general treatment method is to bake the silicone series products at a high temperature after they are molded. This method removes the small oil molecules remaining inside the product, thereby reducing the possibility of oil oozing from the surface of the product. However, using this method will cause waste of energy and increase of labor hours during the long-term high-temperature baking p...
