The invention provides a high-specific-gravity transparent resin composition and a preparation method of particles thereof.The preparation method of the high-specific-gravity transparent resin composition comprises the steps that acrylic acid or (methyl) acrylic acid, pre-smashed brominated epoxy resin, a polymerization inhibitor and an antioxidant are put into a reaction kettle to be mixed, the temperature is increased to 60-70 DEG C, then a reaction catalyst is added step by step, and the mixture is stirred to be uniform; the reaction temperature is kept between 80 DEG C and 90 DEG C for 2-3 hours until the acid value reaches 10-20, then cooling is conducted to 65-75 DEG C, a reactive monomer diluent, a polymerization inhibitor and a toner are added, and the high-specific-gravity transparent resin composition is obtained through a reaction. According to the method, the required reaction temperature is relatively low, high-temperature melting of the brominated epoxy resin is not needed, the conditions of eas
