Anti-sticking coating for cylinder gasket for vehicle and preparation method thereof

The invention relates to an anti-sticking coating for a cylinder gasket for a vehicle and a preparation method thereof The anti-sticking coating for the cylinder gasket for the vehicle comprises 1-20 parts of fluorine-containing silane; 20-50 parts of an alkoxy terminated siloxane polymer; 20-50 parts of hydroxylated polysiloxane; 0.1-5 parts of a brightening agent; 10-70 parts of a diluent; and 0.1-10 parts of a silane coupling agent. The invention also comprises a preparation method of the coating. The preparation method comprises the following steps: mixing fluorine-containing silane, hydroxylated polysiloxane, the alkoxy-terminated siloxane polymer and the brightening agent, dropwise adding a hydrochloric acid solution at 50-90 DEG C, refluxing, adding hexamethyldisilazane, adjusting the pH value to 6.5-7.5, heating to 100 DEG C or above, adding the diluent, after cooling, adding a silane coupling agent to obtain the anti-sticking coating for the cylinder gasket for the vehicle. According to the anti-stic
