The invention relates to a retardant plasticizer methyl silicate ester compound and a preparation method thereof, in particular to methyl silicic acid tris(1-chloro-1-methylethyl)ester and a preparation method thereof. The compound has the structure shown as CH3Si(OC3H6Cl)3. The preparation method comprises the following steps of: mixing methyltrimethoxy silane and 1-chloro propanol in a certain molar ratio with an organic solvent, heating for refluxing, steaming out quantitative methanol generated in reaction by using a fractionating device, and performing passivation treatment to obtain colorless to light yellow liquid, namely the methyl silicate ester. The methyl silicate ester has good retardant plasticization; moreover, the production process is simple, equipment investment is low, cost is low, pollution is avoided and the invention is suitable for industrial production.
