Preparation method of marble adhesive

The invention provides a preparation method of a marble adhesive which is a single-component marble adhesive; an addition mode of variable-temperature polymerization and slow dropwise addition of a monomer and an anionic emulsifier is adopted, and an initiator is supplemented in the middle stage of polymerization on the basis of variable-temperature polymerization. During use, adhesive preparationis not needed, so that time waste and material loss caused by adhesive preparation are reduced; with adopting of variable-temperature polymerization, temperature rise in the later period of polymerization can be avoided, the automatic acceleration phenomenon is overcome to a certain extent, the reaction is close to a constant-speed polymerization reaction, and a high-quality product with more concentrated molecular weight distribution can be obtained. According to the method, the concentration of free radicals in the later period of polymerization can be increased, polymerization is complete,meanwhile, the polymeriza
