[0073] A second aspect of the present invention provides the preparation method of the styrene-acrylic emulsion adhesive used for fabric compounding as described above, comprising the following steps:
[0074] A. Dissolve the above-mentioned emulsifier and pH buffer in 40-50 parts of deionized water, and after the emulsifier is completely dissolved, add the soft monomer, hard monomer and cross-linking monomer of the above-mentioned weight in turn The mixture is fully stirred at 200-300rpm for 20-30min to obtain an acrylate pre-emulsion;
[0075] B, the initiator of the above-mentioned weight portion is dissolved in 10-40 parts of deionized water, and stirring is uniform to obtain an aqueous initiator solution;
[0076] C. Take by weighing 10-15% acrylate pre-emulsion and 30-40 parts of deionized water, at 100-150rpm rotating speed, stir and heat up to 75-85 ℃, add 30-50% by volume Initiator aqueous solution, continue to react at this temperature for 0.5-1h to obtain blue phas...
