Embodiment 1
[0018] A preparation method of water-based heat-sealing glue, comprising the following steps:
[0019] Step 1, in parts by weight, add 0.8 parts of surfactant, 2 parts of plasticizer, 0.1 part of triethanolamine, and 0.5 parts of polyol into water and disperse to obtain mixture A;
[0020] Step 2, in parts by weight, the temperature of mixture A is raised to 50°C, 0.3 parts of acrylic acid, 0.1 part of neoprene, and 0.2 parts of polyvinyl alcohol are added, and the mixture is kept for 3 hours to obtain mixture B;
[0021] Step 3: Add mixture B to 30 parts of polyvinyl acetate resin emulsion in parts by weight, adjust the pH to 6.0-8.0, and obtain mixture C;
[0022] Step 4, in parts by weight, add 2 parts of thickener to mixture C and stir.
[0023] Wherein, the plasticizer is a mixture of dibutyl phthalate and diethylhexyl phthalate in a weight ratio of 1:1; the surfactant is Tween 80 and lauryl sulfate A mixture of sodium in a weight ratio of 4:1.
[0024] In step 3, sodi...
Embodiment 2
[0028] A preparation method of water-based heat-sealing glue, comprising the following steps:
[0029] Step 1, in parts by weight, add 1.3 parts of surfactant, 3 parts of plasticizer, 0.2 part of triethanolamine, and 0.7 part of polyol into water and disperse to obtain mixture A;
[0030] Step 2, in parts by weight, the mixture A is heated to 50-70°C, 0.5 parts of acrylic acid, 0.2 parts of neoprene, and 0.4 parts of polyvinyl alcohol are added, and the mixture is kept for 2 hours to obtain a mixture B;
[0031] Step 3: Add mixture B to 40 parts of polyvinyl acetate resin emulsion in parts by weight, adjust the pH to 6.0-8.0, and obtain mixture C;
[0032] Step 4, in parts by weight, add 5 parts of thickener to mixture C and stir.
[0033] Wherein, the plasticizer is a mixture of dibutyl phthalate and diethylhexyl phthalate in a weight ratio of 1:1; the surfactant is Tween 80 and lauryl sulfate A mixture of sodium in a weight ratio of 4:1.
[0034] In step 3, sodium hydroxi...
Embodiment 3
[0038] A preparation method of water-based heat-sealing glue, comprising the following steps:
[0039] Step 1, in parts by weight, add 1.4 parts of surfactant, 4 parts of plasticizer, 0.3 part of triethanolamine, and 0.7 part of polyol into water and disperse to obtain mixture A;
[0040] Step 2, in parts by weight, the temperature of mixture A is raised to 60°C, 0.7 parts of acrylic acid, 0.2 parts of neoprene, and 0.5 parts of polyvinyl alcohol are added, and the mixture is kept for 3 hours to obtain mixture B;
[0041] Step 3: Add mixture B to 45 parts of polyvinyl acetate resin emulsion in parts by weight, adjust the pH to 6.0-8.0, and obtain mixture C;
[0042] Step 4, in parts by weight, add 7 parts of thickener to mixture C and stir.
[0043] Wherein, the plasticizer is a mixture of dibutyl phthalate and diethylhexyl phthalate in a weight ratio of 1:1; the surfactant is Tween 80 and lauryl sulfate A mixture of sodium in a weight ratio of 4:1.
[0044] In step 3, sodi...
