Problems solved by technology

At present, Dinp is used as the plasticizer in the dipping material. Because Dinp contains benzene, PVC gloves do not meet the requirements of food-grade gloves, and the promotion and application in the food industry is limited.
PE gloves do not contain benzene, and their application in the food industry has been promoted to a certain extent. However, PE gloves are made of PE film after high-temperature ironing, and their watertight performance is far inferior to that of PVC gloves. Decreased food hygiene indicators due to skin contact with food
Moreover, the cost of latex gloves, nitrile gloves and PE gloves is relatively high, which limits the general application in the food industry
At present, PVC gloves without benzene and good watertight performance are still rare, and no media reports

[0022] (1) Put 21% of PN-860 and 16.3% of UN-610 into the mixing container;

[0023] (2) Add 62.3% PVC powder and 0.4% stabilizer, and stir the PN-860, UN-610, PVC powder and stabilizer at 42°C for 3 hours.

[0024] (3) Throw in the viscosity reducer TXIB, and adjust the viscosity of the impregnating material to the viscosity required for production.

[0025] (4) Stand still for 72 hours after filtration.

[0026] (5) Dipping, dripping, baking, secondary dipping, secondary baking, crimping, edge trimming, pre-release, and demoulding are performed in sequence with a hand-shaped mold.

Abstract

The invention relates to the field of glove manufacturing, and especially relates to a modified manufacturing method for a food-grade PVC glove. According to the manufacturing method of the food-grade PVC glove, in an impregnant prepared from PVC powder, a plasticizer, a stabilizing agent and a viscosity reducer, the plasticizer is a combination of PN-860 and UN-610, and the mass percentage of PVC powder, PN-860, UN-610 and the stabilizing agent respectively are 45-80, 10-30, 8.6-24.6 and 0.35-0.65. The PVC glove prepared by employing the method does not contain benzene, is good in water tightness and is accord with the requirements of food-grade gloves.

Description

technical field [0001] The invention relates to the field of glove manufacturing, in particular to the improvement of a PVC glove manufacturing method. Background technique [0002] PVC gloves are widely used in industrial and medical fields because of their tensile strength, elasticity, comfort, etc. are close to latex gloves and nitrile gloves. At present, the manufacturing method of PVC gloves is to prepare four kinds of raw materials of PVC powder, plasticizer, stabilizer and viscosity reducer in a certain order, proportion and time to make a liquid impregnating material, and then use a hand-shaped mold to impregnate and vertically in order. Dropping, baking, secondary dipping, secondary baking, curling, edge trimming, pre-release, and demoulding, PVC gloves can be made. PVC powder, plasticizer, and stabilizer are the main raw materials of the dipping material, and the viscosity reducer is used to dilute the dipping material to meet the customer's requirements for the w...
