Problems solved by technology

Although the production process of gloves made of a single rubber is simple, the functionality is relatively single, and there are many shortcomings.
For example, natural latex gloves are poor in oil resistance, chemical resistance, and abrasion resistance; while nitrile gloves are poor in softness and comfort, etc.
There are also some rubber gloves that only strengthen the thumb and the tiger's mouth to improve the anti-abrasion performance of this part, but do not consider the oil resistance and chemical resistance of the entire glove, especially the air permeability, resulting in the performance of the entire product. Insufficient

Embodiment 1

[0030] Step S1: Impregnate oily PU resin compound: 100 parts by mass of polyester oily PU resin (solid content 28%), 600 parts of DMF, 0.5 part of defoamer (high-carbon alcohol fatty acid ester complex) It is mixed with 0.5 parts of leveling agent polydimethylsiloxane to prepare oily PU resin compound, and the cotton wool glove embryo is impregnated with the oily PU resin compound prepared by the aforementioned process.

[0031]Step S2: Glue dispensing and water washing: place the gloves impregnated with oily PU resin in step S1 for 3 to 8 minutes, then soak in water at a temperature of 30°C for 15 minutes, so that the oily PU resin can fully react with water Completely and solidify; then soak twice in water at 45°C for 30 minutes, on the one hand to promote the PU resin to react more thoroughly, and on the other hand to remove DMF; then soak in water three times at 65°C for 30 minutes , remove DMF again, reduce the content of DMF in the glove; finally oven dry, the temperatur...

Embodiment 2

[0036] Step S1: impregnating oily PU resin compound: 120 parts by mass of polyether type oily PU resin (solid content 22%), 800 parts of DMF, 1.5 parts of defoamer (polyoxyethylene polyoxypropylene pentaerythritol ether) It is mixed with 2 parts of leveling agent (polymethylphenylsiloxane) to prepare an oily PU resin compound, and the knitted glove embryo is impregnated with the oily PU resin compound prepared by the aforementioned process.

[0037] Step S2: Glue dispensing and water washing: place the gloves impregnated with oily PU resin in step S1 for 2 to 6 minutes, then soak in water for 15 minutes at a temperature of 35°C, so that the oily PU resin can fully react with water Completely and solidify; then soak in water twice at 50°C for 30 minutes, on the one hand to promote the PU resin to react more thoroughly, and on the other hand to remove DMF; then soak in water three times at 65°C for 35 minutes , remove DMF again, minimize the content of DMF in the glove; finally ...

Embodiment 3

[0041] Step S1: Impregnate oily PU resin compound: 90 parts by mass of polyether type oily PU resin (33% solid content by mass), 250 parts of DMF, 0.2 part of defoamer (main component polyoxyethylene polyoxyethylene Propanol amine ether) and 0.2 parts of leveling agent (main component polymethylphenylsiloxane) are mixed and prepared to prepare oily PU resin compound, and cotton wool knitted glove embryos or cotton wool glove embryos are impregnated in the oily PU prepared by the aforementioned process Resin compound.

[0042] Step S2: Glue dispensing and washing: place the gloves impregnated with oily PU resin in step S1 for 4 to 8 minutes, then soak in water for 15 minutes at a temperature of 25°C, so that the oily PU resin can fully react with water Completely and solidify; then soak in water twice at 35°C for 35 minutes; then soak in water three times at 60°C for 35 minutes to minimize the content of DMF in the gloves; finally dry in an oven at 110°C ℃, time 40 minutes.

Abstract

The invention provides a preparation method of an oily PU-butyronitrile double-layer composite rubber glove. The preparation method comprises the following steps: S1, soaking with oily PU resin glue material: soaking a glove preform with the oily PU resin glue material, wherein the oily PU resin glue material is prepared by mixing and blending the following components in parts by mass: 90-120 parts of oily PU resin, 250-800 parts of DMF, 0.2-1.5 parts of a defoaming agent and 0.2-2 parts of a leveling agent; S2, glue dripping and water washing: dripping the glue on the glove soaked with the oily PU resin in S1, placing the glove, then putting the glove in water to be soaked and washed, taking out the soaked and washed glove, and then, drying the glove; S3, soaking with butyronitrile latexglue material: soaking the glove treated in S2 with the butyronitrile latex glue material, wherein the butyronitrile latex glue material is prepared by mixing and blending the following components inparts by mass: 90-120 parts of butyronitrile latex, 0.5-4 parts of thickening agent, 0-4 parts of cross-linking agent and 5-10 parts of water; and S4, vulcanizing and drying: vulcanizing and drying the glove treated in S3 to prepare the oily PU-butyronitrile double-layer composite rubber glove. The glove prepared by the method provided by the invention combines the characteristics of oil resistance, chemical resistance, wear resistance and the like of butyronitrile rubber as well as comfort, flexibility and air permeability of PU resin rubber. The invention also relates to the oily PU-butyronitrile double-layer composite rubber glove.

Description

technical field [0001] The invention relates to a method for manufacturing oily PU-nitrile double-layer composite rubber gloves. Background technique [0002] In the past, long-tube labor protection gloves were mostly made of a single type of rubber, such as natural latex gloves, nitrile gloves, neoprene gloves, and butyl gloves. Although the manufacturing process of gloves made of a single rubber is simple, the functionality is relatively single, and there are many shortcomings. For example, natural latex gloves are poor in oil resistance, chemical resistance, and abrasion resistance; while nitrile gloves are poor in softness and comfort. There are also some rubber gloves that only strengthen the thumb and the tiger's mouth to improve the anti-abrasion performance of this part, but do not consider the oil resistance and chemical resistance of the entire glove, especially the air permeability, resulting in the performance of the entire product. Insufficient. Contents of ...
