The invention relates to a preparation method of polyethylene glycol 1000 diacrylate. The steps include: (1) esterification reaction: adding polyethylene glycol 1000, acrylic acid, a solvent toluene, a catalyst p-toluenesulfonic acid, and a polymerization inhibitor p-hydroxyanisole into a reaction kettle, conducting heating under stirring till system backflow, separating the reaction generated water by an oil-water separator, and when no more water is generated, further conducting stirring for 2h, stopping heating, and turning-off stirring, wherein the polyethylene glycol 1000 and acrylic acid are in a molar ratio of 1:1.1-1.2; (2) washing; and (3) carrying out pressure reduction and solvent removal to obtain a finished product. The invention aims to provide a production method that has no need of adopting expensive special equipment during production, can reduce the production cost and improve the market competitiveness of enterprises, so that the product can enjoy greater popularization and application on the market.
