The invention relates to the technical field of dyeing and finishing, and relates to universal digital ink-jet printing priming paste and a preparation method thereof. The universal digital ink-jet printing prime slurry comprises raw materials for preparing deionized water, and also comprises 2-acrylamido-2-methylpropanesulfonic acid, acrylic acid, acrylamide, sodium hydroxide and an initiator; the weight ratio of the 2-acrylamido-2-methylpropanesulfonic acid is 15-30%, the weight ratio of the acrylic acid is 1-5%, the weight ratio of the acrylamide is 1-5%, the weight ratio of the sodium hydroxide is 3-10%, the weight ratio of the initiator is 0.1-10%, and the balance is deionized water. The invention overcomes the defect that the sizing agent for digital printing in the prior art forms sizing spots due to poor fluidity, and obtains the universal digital ink-jet printing primer paste with low cost and high performance. |
