Flexible Glove and the Preparation Method Thereof

A preparation method of flexible gloves comprising the following preparation steps:

• (A) 100 portions (by weight) of at least one of anionic aliphatic polyurethane dispersions;
• (B) 10˜100 portions (by weight) of at least one of self-reactive acrylic emulsions or solutions;
• (C) 0.1˜0.5 portions (by weight) of cure-crosslinking agent, said cure-crosslinking agent is an aqueous or alcoholic solution of amino resin;
• (D) 0˜10 portions (by weight) of waterborne pigment color slurry composition;
• (E) 5˜20 portions (by weight) of a nano-calcium carbonate slurry;
• (F) an agglomerant;
• (G) a waterborne coating;
• (H) acid and alkali cleaning agents;
• (1) cleanse hand-moulds by the alkali cleaning agent of (H), followed by the acid cleaning agent of (H), then by 50˜90° C. hot water;
• (2) dry the hand-moulds cleansed in step (1) under 100˜120° C. atmosphere for 3‥5 min;
• (3) immerse the hand-moulds dried in step (2) in 1˜30% (w/w) of (F), preferably 5˜15% (w/w), then dry it under 80˜110° C. atmosphere for 3˜5 min;
• (4) immerse the dried hand-moulds immersed in step (3) into a premix of (A), (B), (C), (D) and (E) for 5˜7 seconds, and then cure the moulds under 110˜150° C. atmosphere for 20˜60 seconds;
• (5) immerse the hand-moulds cured in step (5) in a dilute solution of (G), the dilution ratio (by weight) is 5˜15 times compared to (F);
• then cure the moulds under 110˜150° C. atmosphere for 10˜20 min;
• (6) cleanse the hand-mould cured in step (5) in 50° C. warm water and leach, then cure the mould under 110˜150° C. atmosphere for 3˜10 min, then demould to thereby obtain the flexible gloves.
