Aqueous gloss oil for beer cartons and preparation method thereof

Abstract

The invention discloses aqueous gloss oil for beer cartons, which is prepared from the following raw materials in percentage by mass: 70%-80% of modified styrene-acrylate emulsions, 10%-20% of styrene-acrylate emulsions, 2%-6% of wear-resistant wax slurry, 0.1%-0.3% of defoamers, 0.1%-0.3% of preservatives and 3%-5% of isopropyl alcohol. The preparation method comprises the following steps of: firstly adding the modified styrene-acrylate emulsions at normal temperature, and then slowly and sequentially adding the defoamers, the styrene-acrylate emulsions, the wear-resistant wax slurry, the preservatives and the isopropyl alcohol when stirring; after adding various raw materials, stirring for 10 minutes at the rotary speed of 500-1000 revolutions / minute to uniformly disperse various raw materials in the system for obtaining the aqueous gloss oil for the beer cartons. The aqueous gloss oil has the advantages of high skid resistance, wear resistance, adhesion resistance, wet-adhesion resistance and waterproofing performance, is suitable for the glossing of the beer cartons and has a good protection action on the beer cartons.

Description

technical field [0001] The invention belongs to a water-based varnish, in particular to a water-based varnish for beer cartons and a preparation method thereof. Background technique [0002] In recent years, the development of my country's beer industry has shown a strong upward trend, and the demand for beer cartons has also increased. The surface of beer cartons often needs to be coated with a layer of water-based varnish, so strict technical requirements are put forward for the performance of varnish. There is a certain pressure in the beer bottle, which is easy to burst. Therefore, in the storage and transportation, it is necessary to ensure that there is enough friction between the cartons to prevent the stacked beer boxes from slipping, causing the beer boxes to tilt, fall, and collide. Causing the bottle of beer to explode. Water-based varnish is coated on the surface of beer cartons, which requires the varnish to have high anti-skid performance. Beer cartons have ...

Problems solved by technology

At the same time, when the boxed beer comes out of the refrigerator and encounters hot air, it will form small water droplets on the surface of the carton. The varnish on the surface of the carton is easy to dissolve in water, and it is easy to make the stacked cartons stick together, damaging the surface of the carton. Printing effect, so the varnish is required to have high anti-wet sticking performance

The technical requirements for the performance of varnish for beer cartons are difficult to achieve for general water-based varnishes
