Abstract

The present invention is water-thinned environment friendly paper polishing oil, and belongs to the field of fine chemical technology. The water-thinned environment friendly paper polishing oil is the reaction product of water dissolved composite monomer, initiator and composite emulsifier. The composite emulsifier consists of non-ionic emulsifier and anionic emulsifier; and the composite monomer consists of methyl methacrylate or styrene, butyl acrylate or butyl methacrylate, acrylic acid or methacrylic acid, acrylonitrile or styrene, hydroxyethyl methacrylate or hydroxyethyl acrylate. The water-thinned paper polishing oil has high wear resistance, good low temperature filming property, high safety and low cost, and the painted paper may be recovered for reuse.

Description

technical field [0001] The invention relates to a paper varnish, which belongs to the field of fine chemicals, in particular to an environment-friendly paper varnish using water as a medium, and also provides a method for manufacturing the water-based varnish. Background technique [0002] At present, most of the paper varnishes produced in China are solvent-based varnishes, which use organic solvents such as styrene as the medium, which are flammable and explosive in operation and application, and the solvents are volatile, and paper products cannot be recycled after plastic lamination Utilization causes environmental pollution and waste of resources. The abrasion resistance of the glazing oil is poor, the low temperature film formation is poor, and the film is easy to crack. Contents of the invention [0003] The purpose of this invention is to overcome the above disadvantages and provide a water-based environment-friendly paper varnish with low cost, high wear resistanc...
