preparation example Construction

[0047] A kind of preparation method of high green environmental protection label glue, comprises the steps:

[0048] Step 1: weighing styrene-based thermoplastic elastomer, styrene-butadiene rubber, EVA, petroleum resin, rosin resin, paraffin wax, softener, and antioxidant according to parts by weight;

[0049] Step 2: heating the reaction vessel to 135-140°C, adding paraffin and softener for stirring and heating;

[0050] Step 3: Add antioxidant, 20wt% petroleum resin and 20wt% rosin resin to the reaction vessel, fill with nitrogen and then vacuumize, control the temperature of the reaction vessel to be 145-150°C, and the melting time is 15-18min, the petroleum resin and The rosin resin melts completely;

[0051] Step 4: Stir and heat until the temperature of the reaction vessel is 165-170°C, first add EVA, the melting time is 8-12min, after the EVA is completely melted, add styrene thermoplastic elastomer, styrene-butadiene rubber, the remaining petroleum resin and the rema...

Abstract

The invention discloses an environment-friendly label adhesive and a preparation method of the environment-friendly label adhesive. The environment-friendly label adhesive comprises the following components by weight: 10-20 parts of styrenic thermoplastic elastomer, 10-20 parts of EVA, 20-30 parts of petroleum resin, 10-20 parts of rosin resin, 5-10 parts of paraffin, 10-20 parts of softening agent, and 1.5-2 parts of antioxygen. The environment-friendly label adhesive has the beneficial effects that the environment-friendly label adhesive reduces the carbon deposit produced in a sunk part ofa compression roller in the coating process, so that the dismounting and cleaning efficiency of the compression roller is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an adhesive, in particular to a green environmental protection label glue and a preparation method thereof. Background technique [0002] All kinds of food packaging on the market often have labels. The label is attached to the food packaging with an adhesive. According to the varieties appearing on the market, the adhesives used for label pasting can be divided into three categories: pressure-sensitive adhesives, hydrosols and water-remoistenable adhesives. Among them, pressure-sensitive adhesives have the characteristics of high initial adhesion, long-lasting adhesion, good adhesion to most packaging materials, and are convenient to use, so they are used in the largest amount in label adhesives. [0003] The Chinese patent with publication number CN105969272A discloses a hot melt adhesive composition for refrigeration labels and a preparation method thereof. The hot melt adhesive composition comprises the following compone...
