Embodiment 1
[0027] The preparation method of zero DMF dipped gloves water-based PU glue, described water-based PU glue is made up of following weight ratio composition:
[0028] Water-based polyurethane dispersion 70%, anti-wear agent 2%, wax emulsion 1%, cell opener 0.5%, wetting agent 0.1%, adhesive 2%, foaming agent 1%, foam stabilizer 1%, association Type thickener 0.4%, deionized water 10%;
[0029] Its preparation steps include:
[0030] S1, take a certain amount of water-based polyurethane dispersion and place it in the mixing tank; the mixing tank is a stainless steel mixing tank with a smooth inner wall;
[0031] S2, an agitator is set outside the stainless steel mixing tank, the driving end of the agitator extends into the stainless steel mixing tank, and is stirred at a speed of 500-1100r / min;
[0032] S3, taking appropriate ratio of deionized water, foaming agent, foam stabilizer, adhesive and wetting agent into the water-based polyurethane dispersion, stirring for 5-13 minu...
