Problems solved by technology

[0003] At present, natural latex examination gloves, nitrile examination gloves, and PVC examination gloves are the main disposable protective products currently used in the medical industry in developed countries such as Europe and the United States. The shortcomings of the product have also produced many shortcomings, such as: ① latex gloves made of natural latex formula have very comfortable fit and good physical properties, but it contains "protein" which causes some Europeans and Americans, especially white Allergic ulcers caused by skin contact with the product
②Although the formula of "Nitrile Rubber Gloves" does not contain allergens of allergic proteins, the gloves feel hard and have poor wearing comfort and the manufacturing cost is higher than that of latex gloves

Abstract

The invention discloses environmentally-friendly polyvinyl chloride / nitrile butadiene rubber (PVC / NBR) composite gloves. The composite gloves are prepared from the following raw materials: PVC paste resin powder, plasticizer, heat stabilizer, NBR, accelerant, vulcanizing agent and color paste in a ratio of 100:(40-60):(0.9-1.8):(25-40):(0.5-1):(0.5-1):(2-5), wherein the plasticizer is ATBC (acetyl tributyl citrate) / polyester plasticizer; the heat stabilizer is phenol-free environmentally-friendly calcium-zinc heat stabilizer; the accelerant is tetramethyl thiuram disulfide / N-cyclohexyl-2-benzothiazole sulfonamide (TMTD / CZ); and the vulcanizing agent is sulfur. The composite gloves have the advantages that the mobility and volatility of the materials in the raw materials are reduced, the energy consumption is lowered, the wearing comfort is improved at the same time, and harm to human bodies is completely avoided.

Description

technical field [0001] The invention relates to a composite glove, in particular to an environment-friendly PVC / NBR composite glove. Background technique [0002] PVC-nitrile composite gloves are a new material "rubber-plastic" composite material obtained by blending polyvinyl chloride paste resin (EPVC) and nitrile rubber NBR through blending modification and chemical crosslinking. The technology covers rubber glove processing technology And PVC plastic processing technology and polymer material blending modified cross-linking technology, environmental protection improvement technology. [0003] At present, natural latex examination gloves, nitrile examination gloves, and PVC examination gloves are the main disposable protective products currently used in the medical industry in developed countries such as Europe and the United States. The shortcomings of the product have also produced many shortcomings, such as: ① latex gloves made of natural latex formula have very comfo...
