Abstract

The invention relates to a preparation method of polyacrylate emulsion bead-planting glue used in a light-reflecting material, which includes steps of preparing a pre-emulsified liquid, preparing an initiator water solution and performing a reaction. In the invention, by means of the polyacrylate emulsion bead-planting glue for replacing solvent-type bead-planting glue, a production cost can be reduced. The aqueous bead-planting glue is excellent in binding performance with a base material. The surface of a bead-planted film is flat, is smooth, is free of bead-leakage and is free of pores. The preparation method is simple in process and is convenient to carry out. The polyacrylate emulsion bead-planting glue is easy to clean, is not less than the solvent-type bead-planting glue in performances, is less in odor, is low in the content of VOC, and is more healthy, safe, environmental-protective and energy-saving.

Description
