Example Embodiment

[0020] Example 1

[0021] 1. Preparation of liquid resin emulsion

[0022] Weigh out 0.3KG of 264 stabilizer, 24881KG of PVA, 60KG of liquid resin, 3KG of 908 emulsifier, and 35.7KG of water. Put 60KG of liquid resin into a closed cylinder, close the cylinder, start the agitator to stir at 60 rpm, turn on the heater, let the temperature of the liquid resin in the cylinder gradually rise to 90°C, and open the vacuum at the same time. Add water 35.7KG, 908 emulsifier 3KG and PVA24881KG to the tank to heat up, when the temperature rises to 90 ℃, add water, emulsifier and stabilizer to the first cylinder in a short time, mix for 40 minutes, turn on The high-speed disperser emulsifies at a high speed for 10-20 minutes at a speed of 1000-1500 rpm.

[0023] 2. Preparation of acrylic mixed emulsion

[0024] Mix 75KG of acrylic emulsion, 7KG of EVA emulsion, and 18KG of vinyl acetate emulsion at room temperature, and use a disperser in a pulling cylinder at 500 to 700 rpm to dispers...

[0031] 2. Preparation of acrylic mixed emulsion

[0032] Mix 75KG of acrylic emulsion, 7KG of EVA emulsion, and 18KG of vinyl acetate emulsion at room temperature, and use a disperser in a pulling cylinder at 500 to 700 rpm to disperse for 10 to 20 ...

Example Embodiment

[0036] Example 3

[0037] The preparation steps are the same as those in Example 1, except that in the preparation of the acrylic mixed emulsion, 65KG of acrylic emulsion, 5KG of EVA emulsion, and 30KG of vinegar-acrylic emulsion were mixed at room temperature, and the dispersing machine was used in the pulling cylinder under the condition of 500-700 rpm. , dispersed for 10 to 20 minutes and mixed evenly.

Abstract

The invention provides a nontoxic and tasteless emulsion adhesive for food packaging, which consists of the following raw materials in percentage by weight: 45-62% of acrylic acid mixed emulsion, 8-10% of rosin emulsion and 30-45% of liquid resin emulsion. The emulsion adhesive has the advantages of high adhesive strength and long opening time, and is suitable for the manual and flow line production of food packaging boxes; moreover, the emulsion adhesive is remarkably convenient to apply and easy to clean.

Description

technical field [0001] The invention relates to the field of food packaging, in particular to an emulsion adhesive used for food packaging outer boxes. Background technique [0002] At present, many food packaging boxes include materials that are in direct contact with food, and most of them use adhesives. Adhesive is an auxiliary material that can bond many materials together. There are many types of adhesives, and there are more packaging materials. For example, adhesive materials include solvent-based, semi-oily, water-soluble, and emulsion-based. The substrates to be bonded include paper, cardboard, plastic materials (OPP, PE, PP, PET, BOPP, PS), wood, aluminum foil, etc. Those skilled in the art choose different adhesives to bond different substrates, so as to realize the purpose of forming different materials into a whole. [0003] The rapid development of the adhesive industry has provided the society with many new types of glue. At the same time, the toxic raw mat...
