Abstract
The invention belongs to silicone rubber art, specifically a kind of high flame retardancy silicon rubber additive and preparation method.It is characterized in that comprising poly-titanium organo-siloxane, methyl phenyl vinyl silicone rubber rubber, hexamethyldisilazane, two two or five vulcanizing agents, aerosil and phosphate flame retardant, its formula consists of weight fraction: poly-titanium organo-siloxane 100 parts, methyl phenyl vinyl silicone rubber rubber 10-100 part, hexamethyldisilazane 3-9 part, two two or five vulcanizing agent 1-6 parts, aerosil 13-30 part, phosphate flame retardant 5-20 part.The silicone rubber products using the present invention to produce has the performance of high flame retardant, is suitable for the application in inflammable and explosive field.
Description
Technical field
The present invention relates to engineering materials field, specifically a kind of high flame retardancy silicon rubber additive and preparation method.
Background technology
Silicon rubber is a kind of specialty elastomer, has the performances such as heat-resisting, low temperature resistant, high insulation, is widely used, and a lot of daily necessities is all produce with it now, also has many other fields also to be unable to do without it.Use the environment of silicon rubber various, have very low temperature field, ultra-high voltage field, even also have explosive inflammable field, so the flame retardant properties improving silicon rubber has very large meaning.
Summary of the invention
The present invention, in order to improve the flame retardant properties of existing silicon rubber, provides a kind of high flame retardancy silicon rubber additive and preparation method.
Object of the present invention is achieved by following technical proposals:
A kind of high flame retardancy silicon rubber additive, it is characterized in that comprising poly-titanium organo-siloxane, methyl phenyl vinyl silicone rubber rubber, hexamethyldisilazane, two two or five vulcanizing agents, aerosil and phosphate flame retardant, its formula consists of weight fraction:
The content of each component described is preferably as follows:
The manufacturer of phosphate flame retardant is Jiangsu Daming Technology Co., Ltd.
Prepare a method for high flame retardancy silicon rubber additive as claimed in claim 1, be prepared according to the following step:
(1) poly-titanium organo-siloxane and methyl phenyl vinyl silicone rubber rubber are placed on mixing half an hour on mixing roll, then add the mixing 0.5-1 hour of hexamethyldisilazane, aerosil and phosphate flame retardant;
(2) mixture placement above-mentioned steps prepared adds two two or five vulcanizing agents and carry out back mixing on mixing roll after 4-5 hour, carry out sulfuration in an oven after fully mixing, oven temperature remains on 170-220 DEG C, and the time is 3-6 hour;
(3) feeding inspection, qualified rear discharging naturally cooling.
The present invention uses phosphate flame retardant, has high flame-retardant property, makes to use the silicon rubber of this additive to be used widely in inflammable and explosive field.
