Abstract

A synthetic method of a low-temperature environmentally friendly type flame retardant silicone acrylic electrostatic flocking adhesive is disclosed. The method is characterized by including preparinga core-layer pre-emulsification liquid and a shell-layer pre-emulsification liquid separately; adding dropwise the core-layer pre-emulsification liquid and an initiator solution into a container at the same time to obtain a seed emulsion; then adding dropwise the shell-layer pre-emulsification liquid and an initiator solution into the seed emulsion at the same time; maintaining the temperature after material addition is finished; taking the product out of a reactor; naturally cooling the product to room temperature; performing filtration to obtain a milk-white emulsion through which blue lightcan penetrate; adding adipic dihydrazide into the milk-white emulsion; and stirring the mixture to obtain the uniform and stable adhesive. An in-situ polymerization method, introduction of new functional monomers and multi-component copolymerization are adopted to prepare the phosphorus-containing silicone acrylic emulsion stable to store and silicone acrylic latex having intrinsic flame retardant performance, so that a polyacrylate emulsion after complete polymerization has certain flame retardant performance, the dosage of a blending flame retardant is reduced and flocking effects are improved.
