Abstract
A disposable 4G highly elastic gloves processing process comprises a processing process flow, formula material and proportion preparation, and processing method steps. A pair of highly elastic gloves disclosed by the invention adopts a special production process and a novel nontoxic environmental friendly raw material to compound with NBR (nitrile-butadiene rubber). The process reduces the mobility and the volatility of the raw material due to the improvement of the process; reduces raw material consumption; successfully co-blends and cross-links the NBR into the disposable PVC gloves for the first time; and forms a pure environmental friendly, highly elastic and comfortable wearing compound gloves.
Description
Technical field
The present invention relates to the processing technology of the high-elastic PVC material of a kind of disposable 4G gloves.
Background technology
The PVC gloves are to be that primary raw material is made through technologies such as mix, filtration, deaeration, bakings and formed with PVC paste resin and plasticizer and calcium-zinc composite stabilizing agent; Be widely used in many industries and every field such as hospital, family, electron trade, food service industry, gardening plantation, mainly play to isolate and pollute, protect the both hands effect.It is relatively poor that existing P VC gloves resilience is poor, percentage elongation is on the low side, wearing is fitted chirality.
Summary of the invention
The present invention is in order to address the above problem; The processing technology of the high-elastic PVC material of a kind of disposable 4G gloves is provided; Purpose is: through obtaining preferable product to raw-material blending and modifying, promote the physical property of gloves, improve the right chirality of gloves simultaneously and dress comfortableness.
Technical solution of the present invention:
The high-elastic gloves processing technology of disposable 4G, it is characterized in that: said processing process is: raw material detection, batching, stirring, filtration, vacuum defoamation, leave standstill processing, dipping gloves, hang down to drip backflow, a plasticizing forming, once vulcanize, cool off, flood PU, the demoulding, post-cure, process sampling observation, packing, process inspection, finished product put in storage; A said unnecessary material of backflow that hangs down continues to use as batching.
The high-elastic gloves processing technology of disposable 4G is characterized in that: prescription materials and ratio are following: PVC1 sticks with paste 50 parts of resin-oatmeals, PVC2 sticks with paste 30 parts of resin-oatmeals, 20 parts of resin-oatmeals of PVC3 paste, plasticizer I 40-60 part, plasticizer II 10-20 part, plasticizer III 10-20 part, zinc calcium heat stabilizer 0.9-1.8 part, NBR 25-40 part, promoter 0.5-1 part, vulcanizing agent 0.5-1 part; Said prescription materials are through blending and modifying and chemical crosslinking modified producing.
Said polychloroethylene with high polymerization degree is stuck with paste resin (PVC) and is handled and NBR (NBR) material and plasticizer blending and modifying, increases goods tension intensity and elongation at break.
The high-elastic gloves processing technology of disposable 4G, it is characterized in that: processing method comprises the steps: the first step, it is subsequent use to choose raw material by formula rate;
Second step added earlier plasticizer, added NBR and no phenol environment-friendly calcium zinc heat stabilizer then, and high-speed stirred 60 minutes;
In the 3rd step, slowly add PVC and stick with paste resin-oatmeal, high-speed stirred 2-3 hour then;
The 4th step added vulcanizing agent sulphur and TMTD/CZ promoter again, stirred then 20 minutes, and the slurry that mixes is filtered with 150～200 order stainless steel filtering nets;
In the 5th step, the slurry that filtration is good is put into vacuum drying chamber and is used vavuum pump to carry out vacuum froth breaking and slurry preheating, is preheating to 50-60 ℃, and preheating is 1 hour;
The 6th step, dip forming in the simulation baking oven of mould is housed, the control oven temperature is raised to 240 ℃ and smoked 5-9 minute;
In the 7th step, the band mould takes out and is cooled to 90 ℃ of dipping PU, and crimping promptly becomes product.
1), PVC1 sticks with paste resin-oatmeal: high polymerization degree powder, plasticizing forming prescription materials title, type and Action Specification:.
2), PVC2 sticks with paste resin-oatmeal: copolymerization powder, plasticizing forming.
3), PVC3 sticks with paste resin-oatmeal: low polymerization degree powder, plasticizing forming.
