Problems solved by technology

The paper water-based varnish prepared by the above preparation method has complicated processes and formulas, and cannot be glazed by calendering technology.
Since the water-based glazing oil obtained according to this formula and preparation method needs to be calendered, the glazing oil or even the entire paper will stick to the calendering mold, which cannot meet the requirements.

Embodiment Construction

[0025] The invention is further illustrated by the following examples.

[0026] Take by weighing 30 kilograms of acrylic monomers, 20 kilograms of alcohol polar solvents, 10 kilograms of auxiliary agents, 40 kilograms of water, 0.5 kilograms of initiators, and 0.09 kilograms of release agents for subsequent use; the above-mentioned acrylic monomers are acrylic acid; The alcohol polar solvent is any one of n-butanol, tert-butanol, isopropanol, ethylene glycol ether or propylene glycol ether, and what this embodiment uses is propylene glycol ether; the auxiliary agent is a defoamer and leveling agent It is a mixture of antifoaming agents; the model of its defoaming agent is 082, the main component is non-polysiloxane (silicone), a mixture of mineral oil containing hydrophobic particles, it has good water dispersibility, antifoaming and defoaming effects Good; the type of leveling agent is 455, the main component is modified silicone, which is universal for water and oil, and has...

Abstract

The invention discloses a kind of water glazing paint and the preparation method, belonging to high polymer material technique field. It is characterized in that comprised raw material and their weight proportion are as follows: acrylic acid series monomer 20- 50 units, alcohol polar solvent 10- 30 units, adjuvant 10- 20 units, water 20- 40 units, initiator 0.3- 0.8 unit; mixing acrylic acid series monomer and alcohol polar solvent, adding initiator, carrying out polymerization reaction under vacuum condition or under protection of nitrogen gas, getting polymer with molecular weight being 5000- 15000, adding neutralization agent, adjuvant and releasing agent into polymer, stirring, adding water to dilute, and getting final product. The product is characterized by little toxicity and smell, little environmental pollution, good lustrousness, good wear-resisting and water- proof property. It can be widely used for fine decoration of packing surface with various paper.

Description

【Technical field】 [0001] The invention belongs to the technical field of polymer materials, and relates to a formula and a preparation method of water-based glazing and calendering oil for paper. 【Background technique】 [0002] At present, in order to ensure the film-forming ability and glossiness of most water-based varnishes sold on the market, the content of film-forming aids accounts for more than 20% of the solvent part, and some even reach as high as 70%. Water-based varnish. The boiling point of film-forming aids is generally high, which reduces the drying speed of the film and cannot meet the needs of high-speed printing. At the same time, it increases the product cost and brings environmental pollution. In addition, in order to improve the wear resistance of the glazing coating, wax powder or wax paste is usually added to the water-based glazing oil, but the dispersibility of the wax powder and wax paste is poor, and it is easy to condense and precipitate, which wi...
