Embodiment 1

[0016] The production formula (by weight) of post-crosslinking elastic transfer film latex: 1 part of acrylic acid, 6 parts of E44 epoxy resin, 3 parts of triethylenetetramine, 20 parts of butyl acrylate, 70 parts of styrene, 5 parts of acrylamide part, 0.5 part of initiator, 2 parts of emulsifier, and 0.3 part of defoamer.

[0017] Production steps of post-crosslinked elastic transfer film latex:

[0018] (1) Dissolution of epoxy resin: add E44 epoxy resin to acrylic acid, butyl acrylate and styrene to fully dissolve until completely transparent, and set aside;

[0019] (2) Preparation of pre-emulsion: add water to the pre-emulsification tank, then add acrylamide, a part of emulsifier and a part of initiator, and stir until completely dissolved; then add the mixture obtained in step (1) and dissolve epoxy resin Monomer, fully emulsified to obtain a pre-emulsion;

[0020] (3) Emulsion synthesis: add remaining emulsifier, water and buffering agent in reactor, heat up while st...

Embodiment 2

[0022] The production formula (in parts by weight) of post-crosslinking elastic transfer film latex: 3 parts of acrylic acid, 10 parts of E44 epoxy resin, 2 parts of triethylenetetramine, 30 parts of butyl acrylate, 60 parts of styrene, 3 parts of acrylamide 1 part, 1 part of initiator, 3 parts of emulsifier, 0.5 part of defoamer.

[0023] The production steps of the post-crosslinked elastic transfer film latex are the same as in Example 1.

Embodiment 3

Abstract

The present invention discloses a post-crosslinked elastomeric transfer film emulsion and a preparation method thereof. The emulsion comprises the following components in parts by weight: 1-5 parts of acrylic acid, 6-15 parts of epoxy resin, 1-3 parts of triethylene tetramine, 20-40 parts of butyl acrylate monomer, 50-70 parts of styrene, 1-5 parts of acrylamide, 0.5-1.5 parts of initiator, 2-4 parts of emulsifier, and 0.3-1 part of antifoaming agent. The preparation method of the emulsion comprises the steps of dissolving epoxy resin, preparing a pre-emulsion, synthesizing an emulsion and the like. According to the technical scheme of the invention, the above post-crosslinked elastic transfer film emulsion is adopted to replace the BOPP and PE films of film-coated products, and is high in light, high in brightness, abrasion resistant, folding resistant, degradable, recyclable, good in environmental protection property and low in cost. The post-crosslinked elastic transfer film emulsion can be used as the oil polish of paper packages and can also be used as the water-based paint glossy topcoat.

Description

technical field [0001] The invention relates to the technical field of paper packaging film coating, in particular to a post-crosslinking elastic transfer film latex and a preparation method thereof. Background technique [0002] Real life is full of various and colorful packaging, and packaging is like a coat, which is becoming more and more important. China has become the largest carton producer in the world, accounting for 19.3% of the world's total and 30% of Asia's total. [0003] In order to ensure the printing quality of paper packaging surface paper, the surface is generally treated with film coating, varnish, and UV oil to improve the effects of wear resistance, scratch resistance, water resistance, and gloss and color retention. Film-coated products have excellent brightness, wear resistance and water resistance, good hand feeling, good flexibility and bending resistance, but poor environmental protection, difficult to recycle, and secondary pollution problems; var...
