A material feeding method and a device thereof in organic silicone resin production are disclosed. An organic silicone material barrel is arranged at a position higher than the position of a mixed monomer material reactor for organic silicone resin production and a feeding device like siphon pipe is arranged between the organic silicone material barrel and the mixed monomer material reactor; one end of the feeding device is connected to the cover of the organic silicone material barrel through a connecting device and the other end is connected with the material inlet of the mixed monomer material reactor for organic silicone resin production through a hose, making the part from the entrance of the material inlet pipe of the feeding device to the material inlet of the mixed monomer material reactor for organic silicone resin production resemble a siphon pipe. A nitrogen inlet is arranged on the screw threads which connect the feeding device and the organic silicone material barrel. Thematerial in the organic silicone material barrel is firstly pressed into the feeding device by the nitrogen and when the organic silicone material in the feeding device flows into the mixed monomer material reactor for organic silicone resin production and develops into siphon effect, the nitrogen can be closed and then the material in the organic silicone material barrel is pumped due to the siphon effect.
Description
technical field [0001] The invention relates to a method and device for producing silicone resin, in particular to a method and device suitable for feeding raw materials for producing silicone resin, especially suitable for feeding easily hydrolyzed chlorosilane monomers. Background technique [0002] Silicone raw material, silane monomer, is a highly dangerous product that is easy to corrode and explode. It is easy to be hydrolyzed in the air to produce a large amount of hydrochloric acid mist, and most of the silane monomer has a low boiling point, so it is easy to be taken away by vacuum, resulting in the ratio of raw materials. Changes and a large amount of hydrogen chloride gas are pumped into the vacuum pump to cause corrosion and other problems, so the raw material feeding device for silicone resin production is generally carried out by nitrogen pressure. However, a large amount of hydrogen chloride gas often leaks when only nitrogen gas is used, causing breathing dif...
