Specifically, the peak value of the separation strength of the non-woven fabric for printing is 16.5-24.2N, and the non-woven fabric for printing is free of bubbles and delamination after being placed for 72 hours.
The acrylic resin of example 6 has a small viscosity at 25 ℃ and thus the peak value of the separation strength of the composite adhesive is small and the adhesive property is deteriorated.
The carboxymethyl starch ether of example 7 or 8 has too small or too large degree of substitution, which does not optimize the adhesive property of the compound adhesive.
Example 9 replacement of the inorganic salt with sodium acetate decreased the peak separation strength and poor adhesion.
Comparative example 1, which does not contain carboxymethyl starch ether, comparative example 4, which has too high content of inorganic salt, causes a small peak value of separation strength, deteriorated adhesive property, and deteriorated stability.
Comparative example 2 the carboxymethyl starch ether content is too high and comparative example 3 does not contain inorganic salts, which affects the adhesive properties of the compound gum.
