Embodiment 1-5 and comparative example 1-3

[0061] The specific components and component contents (in parts by weight) of the glues of Examples 1-5 and Comparative Examples 1-3 are shown in Table 1.

[0062] 1. Prepare the quick-drying environment-friendly glue of Examples 1-5 according to the following preparation process:

[0063] Step 1, mixing vinyl acetate and hydroxyethyl acrylate and stirring evenly to obtain monomer mixture 1, which is set aside;

[0064] Mix allyl glycidyl ether, acrylic acid, and diacetone acrylamide and stir evenly to obtain monomer mixture 2, which is set aside;

[0065] Ammonium persulfate is configured as a 2wt% aqueous solution for subsequent use;

[0066]Step 2, add deionized water, polyvinyl alcohol 2699, 35% by weight PEG-4 laurate and sodium bicarbonate into the reactor, stir, then heat up to 90-95°C, fully dissolve;

[0067] Step 3, cool down to 60-70°C, slowly add 50% by weight monomer mixture 1 and 25% by weight ammonium persulfate aqueous solution, heat up to 88-95°C, keep warm ...

Abstract

The invention provides rapid-drying environment-friendly glue suitable for a toy book mounting process. The rapid-drying environment-friendly glue is prepared from the following components: deionizedwater, polyvinyl alcohol 2699, PEG-4 laurate, sodium bicarbonate, ammonium persulfate, vinyl acetate, hydroxyethyl acrylate, allyl glycidyl ether, acrylic acid, diacetone acrylamide, glycerol, dioctylsodium sulfosuccinate and tributyl citrate. The rapid-drying environment-friendly glue is small in expansion and contraction along with the change of temperature and humidity, so that the rapid-drying environment-friendly glue is good in mounting effect, flat, free of warping, easy to dry, not easy to fall off, excellent in temperature resistance, moisture resistance and heat resistance, high insolid content and small in deformation degree, does not contain aldehyde compounds, and is environment-friendly and pollution-free. Various non-environment-friendly substances forbidden to be used inthe ROHS instruction of the European Union are not used, and the rapid-drying environment-friendly glue is suitable for the toy book mounting process.

Description

technical field [0001] The invention relates to the technical field of water-based adhesives, in particular to a quick-drying environmental-friendly glue suitable for a toy book mounting process and a preparation method thereof. Background technique [0002] Children's toy books are generally made and bound by soft materials (such as EVA materials, foam, etc.) and hard paper. shape. Specific patterns and characters can be printed on the hard paper, which can be read as a book. The pages have a certain thickness, which is very suitable for children to read. Among them, some plates with specific patterns can be taken out from the pages and placed again, which is very interesting. At present, when making such books, water-based glue is often used for bonding. [0003] Water-based polyvinyl acetate emulsion adhesive uses water as the dispersion medium, which is friendly to the environment, easy to store, and has no potential safety hazards. It is widely used in the fields of a...
