Spraying glue for water-based bags, suitcases and handbags and preparation method thereof

[0015] Embodiment 1: a kind of water-based bag handbag spray glue, is made up of the raw material of following weight: polybutadiene 55kg, cornflour interpolymer 3kg, hydroxymethyl cellulose sodium 28kg, ammonium gum 4kg, defoamer 3kg .

[0016] Polybutadiene is a highly crystalline butadiene dispersion, the solid content of the high crystalline butadiene dispersion is 55%, the pH value is 13, the viscosity is 100Pa·s, the density at room temperature is 1.12%, and the water content is 45wt %.

[0017] The corn flour copolymer is composed of corn starch and water, the quality of corn starch accounts for 10% of the corn flour copolymer, and the water is boiling water at 100 °C. When preparing the corn flour copolymer, the cornstarch is added into boiling water and boiled for 3 minutes, and then it becomes a paste after cooling.
