Problems solved by technology

[0003] In the prior art, some domestic companies adopt a two-step coating method, that is, the first pass is to pre-coat a layer of primer with good adhesion on the film surface of PP artificial synthetic paper. Apply a layer of functional coating to achieve the purpose of replacing paper with film. In this coating method, two sets of baking equipment are needed, which not only wastes energy consumption, but also reduces production efficiency and increases production costs. The efficiency of production equipment is bound to be low, the energy consumption is high, the yield is low, and the cost of manpower and material resources is high.

Abstract

The invention relates to a single-component emulsion suitable for PP artificial synthetic paper surface coating and a synthesis method of the single-component emulsion, and is characterized in that when 60%-1% of a pre-emulsification monomer is left in the later stage of a polymerization process, a special monomer is added into a pre-emulsification kettle to be dropwise added and participates in a polymerization reaction, so that the use efficiency of the special monomer is improved; in the drying process of film formation, because addition is carried out at the latter part, the situation that the special monomer is wrapped in latex particles by other monomers is greatly reduced, the efficiency of the special monomer participating in the cross-linking reaction in the film forming stage is improved, the usage amount of the special monomer is reduced, and the same effect that the usage amount of the special monomer is larger is achieved.

Description

technical field [0001] The invention relates to the technical field of film coating, in particular to a one-component emulsion suitable for surface coating of PP artificial synthetic paper and a synthesis method thereof. Background technique [0002] With the development of society, the digitalization of commodity circulation, express delivery, logistics, and the uniqueness and traceability of each commodity have given rise to the uniqueness, speed, and ease of use of each commodity label. PP artificial synthetic paper labels Emerged as the times require, it has various advantages such as economy, water resistance, tear resistance, alcohol resistance, moisture resistance, and quick use. PP artificial synthetic paper labels have developed rapidly in recent years and gradually replaced some paper applications. PP artificial synthetic paper labels Paper, the most critical core technology is that the coating on the surface has various properties similar to paper, which puts forw...
