Problems solved by technology

[0004] However, the water-based box paste glue currently on the market is basically a single-component non-crosslinked system, which is mainly resistant to high temperature, low temperature and normal temperature and high humidity, such as a water-based sealing glue emulsion disclosed in Chinese invention application CN108034018A And its preparation method, the sealing glue has high temperature resistance and low temperature resistance performance, but can not adapt to the environment of high humidity; Another example is a kind of water-based sealing adhesive adhesive emulsion preparation method disclosed in Chinese invention application CN106479408A, which mainly improves the sealing glue low-temperature film-forming properties and bond strength, but no improvement in high-temperature and high-humidity resistance

preparation example Construction

[0030] The present invention also provides the preparation method of above-mentioned water-based box glue, and this preparation method comprises the following steps:

[0031] Step 1, adding the weighed polyacrylate emulsion into the container;

[0032] Step 2. Add the weighed carboxylated styrene-butadiene latex, vinyl acetate-ethylene copolymer emulsion, water-based tackifying resin, water-based one-component crosslinking agent, wetting agent, and defoaming agent to the container in sequence under the stirring action of the disperser. agent and preservative, stirring for 20min under the condition of 300~500r / min;

[0033] Step 3. Continue to add thickener to the container until the viscosity of the system reaches 8000-13000mPa·s;

[0034] Step 4, using a filter screen to filter to obtain water-based box glue.

[0035] Wherein, in step 1, the container is a beaker, and the weighing tool is an electronic balance; in step 2, the disperser is a stirring sand mill disperser; in ...

Embodiment 1

[0048] In this embodiment, the water-based box glue includes the following components: 80 parts of water-based polymer, 20 parts of water-based tackifying resin, 2.5 parts of water-based one-component crosslinking agent, 0.3 parts of defoaming agent, 0.2 parts of wetting agent, 0.1 part of preservative, 0.8 part of thickener. Among them, the water-based polymer is a mixture of polyacrylate emulsion, carboxylated styrene-butadiene latex and vinyl acetate-ethylene copolymer emulsion, and the ratio of polyacrylate emulsion, carboxylated styrene-butadiene latex and vinyl acetate-ethylene copolymer emulsion is 40:20 : 20; the water-based tackifying resin is rosin polyol resin; the water-based one-component crosslinking agent is a mixture of ionic crosslinking agent and multifunctional adhesion promoter, and the ratio of ionic crosslinking agent and multifunctional adhesion promoter For: 1.0:1.5; defoamer is mineral oil defoamer; wetting agent is sodium sulfosuccinic acid diester; p...

Embodiment 2

[0050] In this example, the composition of the water-based box glue is similar to that of Example 1, except that it is different from Example 1: 80 parts of water-based polymer, polyacrylate emulsion, carboxylated styrene-butadiene latex and vinyl acetate-ethylene copolymer The ratio of the emulsion is: 30:30:20; the ratio of the water-based one-component cross-linking agent is 2.5 parts, and the ratio of the ionic cross-linking agent and the multifunctional adhesion promoter is: 1.5:1.0.

Abstract

The invention discloses a high-temperature and high-humidity-resistant water-based box pasting adhesive, which comprises the following components in parts by weight: 60-90 parts of water-based polymer, 10-40 parts of water-based tackifying resin, 0.5-4 part of a water-based single-component cross-linking agent, 0.05-0.3 part of a defoaming agent, 0.1-0.5 part of a wetting agent, 0.05-0.2 part of apreservative and 0.05-0.8 part of a thickening agent, wherein the water-based polymer is a mixture of polyacrylate emulsion, carboxylic butadiene-styrene latex and vinyl acetate-ethylene copolymer emulsion. Compared with an existing water-based box pasting adhesive, the cross-linking degree between polymer molecular chains is improved by combining different water-based polymers and adding the single-component cross-linking agent, the high and low temperature resistance and high temperature and high humidity resistance can be met at the same time, and the adhesive failure problem of a packaging box in the transportation process is prevented.

Description

technical field [0001] The invention relates to water-based box glue, in particular to a water-based box glue resistant to high temperature and high humidity and a preparation method thereof. Background technique [0002] Box glue, also known as edge-sealing glue, is used in the last sealing process of packaging box manufacturing. The packaging sheet is edge-sealed by a folder-gluer and glued into a box with a three-dimensional structure. The quality of the bonding performance of box glue to the bonding surface of packaging materials determines the service life of the packaging box, and its importance is self-evident. With the rapid development of packaging materials and customers' higher and higher requirements for packaging materials, various box gluers have emerged as the times require. But generally speaking, the current box gluers on the market are mainly water-based and hot-melt. Xylene-based organic solvents to increase the adhesion to difficult-to-stick substrates,...
