Anti-sublimation silica gel printing coating and preparation method thereof

[0035] The preparation method includes the following steps:

[0036] Step 1, prepare anti-lifting base silica gel: Ethylene polysiloxane, orthosilicate and n-heptane are prepared in a mixture of 500-1000 rpm rotational speeds of 15-30 min, and mix evenly, add deionized water. The mixture was continued for 5-10 min to give a mixed solution, and the mixed solution was placed in a pressure-resistant hydrothermal reaction kettle, and the reaction was reacted at 120-150 ° C for 8-10 h to obtain a lifted base silicone;

[0037] Step 2, prepare a component: Add white carbon black and platinum catalyst to the anti-lifting base silica gel, uniformly dispersed by the planetary mixer, and remove the residual n-heptane and deionized water at a temperature of from 100 to 10 ° C. A component;

[0038] Step 3: Preparation of B components: Silicone oil and inhibitors are uniformly dispersed in a mixer of 500-1000 rpm to 5-10 min to obtain B components;

[0039] Step 4: Preparation of anti-lifting...

[0044] This example uses a method of preventing subtilizing silica gel printing coatings, which is prepared for the preparation of anti-lifting silicone printing coatings;

[0045] The preparation method includes the following steps:

[0046] Step 1: Preparation of anti-lifting base silica gel: 100 parts of the two-terminal vinyl polymethylsiloxane, 5 parts of n-silicate and 10 parts of n-heptane are uniformly dispersed in a mixer of 500 rpm rotational speeds 30 min, and mix Uniform, then 0.05 parts of deionized water, continued for 10 min to obtain a mixed solution, and the mixed solution was placed in a pressure-resistant hydrothermal reaction kettle, and the reaction was reacted at 120 ° C for 8 h, resulting in anti-lifting base silica gel; wherein said The viscosity of the double-end vinyl polymethylsiloxane is 1000 mPa · s, and the vinyl content is 0.2%;
