Embodiment 1
[0030] A preparation process for naturally cracked foam-dipped gloves, comprising the following steps:
[0031] (1) Material preparation: natural latex; the foaming agent is potassium oleate, the mass fraction of which is 1‰ of the natural latex; the thickener is casein, and the mass fraction of the natural latex is 5‰;
[0032] Described natural latex is the three trees brand natural latex of import in Thailand, 205Kg / barrel, and mass concentration is 61%.
[0033] (2) Mechanical foaming: Add natural latex, foaming agent and thickener into the liquid mixing and stirring device according to the ratio of step (1), control the speed at 500rad / min, stir for 1 hour, and control the foaming volume at 1.5 times , to get foam gum.
[0034] (3) Chemical cracking: control the ambient temperature at 22°C, put the hand mold on the glove embryo and immerse it in the coagulant for 5 seconds, then immerse it in the foaming glue obtained in step (2) for 1-2 seconds, and evenly coat the glu...
