Embodiment 1
[0041] Present embodiment is a kind of technology that utilizes novel environment-friendly water-based latex coagulant to prepare nitrile coated gloves, and it comprises steps:
[0042] S1: 20 parts by mass of acrylamide (gel monomer), 2 parts by mass of ammonium persulfate (initiator), 2 parts by mass of ferrous chloride (reducing agent), 5 parts by mass of N, N-methylenebispropylene Amide (crosslinking agent), 1 mass part of sodium carboxymethylcellulose (thickener), 3 mass parts of calcium chloride (destabilizer), 67 mass parts of water are mixed, and the pH is adjusted with ammonia water (neutralizer) Stir evenly at 9.30°C to prepare a new type of environmentally friendly water-based coagulant.
[0043] S2: put the polyester flat glove embryo on the hand mold, and raise the temperature to 80°C.
[0044] S3: Soak the glove embryo heated in S2 with the coagulant in S1, shake the water 10 times, and homogenize the water for 3 minutes.
[0045] S4: impregnation with pre-vulc...
Embodiment 2
[0050] Present embodiment is a kind of technology that utilizes novel environment-friendly water-based latex coagulant to prepare natural rubber wrinkled gloves, and it comprises steps:
[0051] S1: 25 parts by mass of acrylamide (gel monomer), 3 parts by mass of ammonium persulfate (initiator), 3 parts by mass of ferrous chloride (reducing agent), 5 parts by mass of N, N-methylenebispropylene Amide (crosslinking agent), 1 part by mass of sodium polyacrylate (thickener), 3 parts by mass of calcium nitrate (destabilizer), and 60 parts by mass of water are mixed, 0.5 part of sodium hydroxide is used to adjust the pH to 7, and stirred at 30°C Evenly, a new type of environmentally friendly water-based coagulant is prepared.
[0052] S2: put the polyester flat glove embryo on the hand mold, and raise the temperature to 70°C.
[0053] S3: Soak the glove embryo heated in S2 with the coagulant in S1, shake the water 10 times, and homogenize the water for 3 minutes.
[0054] S4: impr...
Embodiment 3
[0060] Present embodiment is a kind of technology that utilizes novel environment-friendly water-based latex coagulant to prepare natural rubber coated gloves, and it comprises steps:
[0061] S1: 20 parts by mass of vinyl alcohol (gel monomer), 1.5 parts by mass of ammonium persulfate (initiator), 2 parts by mass of ferrous chloride (reducing agent), 5 parts by mass of N, N-methylenebispropylene Amide (crosslinking agent), 2 parts by mass of sodium polyacrylate (thickener), 2 parts by mass of calcium nitrate (destabilizer), and 67.5 parts by mass of water are mixed, 0.5 part of sodium hydroxide is used to adjust the pH to 7, and stirred at 30°C Evenly, a new type of environmentally friendly water-based coagulant is prepared.
[0062] S2: Put the polyester fully and half-soaked glove embryo on the hand mold, and raise the temperature to 80°C.
[0063] S3: soak the glove embryos heated in S2 with the coagulant in S1, shake the water 20 times, and homogenize the water for 4 min...
