Problems solved by technology

[0007] The object of the present invention is to provide a kind of polyacrylate emulsion and synthetic method, this polyacrylate emulsion does not use organic solvent, non-toxic environmental protection, and preparation method can overcome the ubiquitous "heat" in polyacrylate emulsion synthesized by traditional emulsion polymerization method. Sticky, cold and brittle", not resistant to organic solvents and other defects, applied in PVC wallpaper printing ink, can solve the problems of high temperature stickiness, precipitation of plasticizers and resistance to organic solvents such as alcohol to wipe, etc.

Abstract

The invention discloses a polyacrylate emulsion and a preparation method thereof. The polyacrylate emulsion is prepared from the following raw materials in parts by weight: 21.1-35.3 parts of a pre-emulsion in a nuclear layer, 21.3-34.1 parts of a pre-emulsion in a crosslinking layer, 8.05-12.2 parts of a pre-emulsion in a shell, 22.21-34.43 parts of initiator aqueous liquor, 0.01-0.08 part of an anionic emulsifier d, 0.04-0.32 part of a non-ionic emulsifier d and 20 parts of deionized water d. The solid content of the target emulsion product disclosed by the invention is over 45%, the storage stability of the emulsion through freeze-thaw stability test is longer than 6 months, and the coating is good in temperature resistance. The emulsion is non-sticky at 200 DEG C, and the adhesive force of the coating to a PVC (polyvinyl chloride) substrate reaches level 1, so that the problems that PVC wallpaper is sticky at high temperature, easy in separation of a plasticizer and intolerant to wiping by organic solvents such as alcohol and the like can be effectively solved.

Description

(1) Technical field [0001] The invention relates to a polyacrylate emulsion, in particular to a polyacrylate emulsion used for PVC wallpaper printing ink and a preparation method thereof. (2) Background technology [0002] As an interior decoration material, wallpaper has developed rapidly in my country in recent years. Among them, PVC (polyvinyl chloride) wallpaper is widely used because of its good flame retardancy. PVC wallpaper is a composite material with paper as the base material, PVC plastic coating as the surface layer, and printing ink on it to obtain various exquisite patterns. PVC wallpaper has the advantages of beautiful, durable, high strength, anti-pull, and easy to paste. However, it has the disadvantages of being sticky at high temperature, releasing hydrogen chloride gas which is harmful to human health, migration and exudation of plasticizers used in large quantities, resulting in easy dust absorption on the surface, and decreased wear resistance. There...
