Embodiment 1

[0014] like figure 1 Shown, a kind of butyronitrile strengthens PU coating glove, comprises glove core 5 and PU coating 6, and glove core 5 comprises palm portion 1, finger portion 2 and close mouth portion 3, and PU coating 6 is arranged on palm portion 1 and The front of the finger portion 2, the thumb and forefinger of the finger portion 2 and the tiger's mouth are provided with a nitrile rubber coating 4.

[0015] During production, first put on the gloves coated with PU coating on the special hand, and then dip the thumb, forefinger and tiger's mouth with DMF aqueous solution at a specific angle. After the DMF aqueous solution is dried, the thumb Dip the index finger and tiger's mouth in nitrile rubber liquid, the dipping time is 0.2s, turn over the hand after dipping to make the glue not flow randomly, then dry and vulcanize at 110°C for 1 hour, and finally get the finished product after cooling and demoulding . The above-mentioned nitrile rubber liquid is formed by mi...

Abstract

The invention discloses a butyronitrile-reinforced glove with a PU (polyurethane) coating. The butyronitrile-reinforced glove comprises a glove core and the PU coating. The glove core comprises a palm portion, a finger portion and a folding portion. The PU coating is arranged on the front sides of the palm portion and the finger portion. The butyronitrile-reinforced glove is characterized in that nitrile rubber coatings are arranged on the thumb and the index finger of the finger portion and at the joint between the thumb and the index finger. The butyronitrile-reinforced glove has the advantages that the nitrile rubber coatings are arranged on the thumb and the index finger and at the joint between the thumb and the index finger in a dipping mode, so that the glove is durable and wear-resisting, and flexible to use; meanwhile, production technology is simple, operation is facilitated, and production efficiency is high.

Description

technical field [0001] The invention relates to a nitrile reinforced PU coated glove and a production process thereof, belonging to the technical field of labor protection gloves. Background technique [0002] Under normal conditions, the durability of the rubber surface of PU coated gloves is very low, especially the tiger's mouth part is used most frequently in specific working environments and is also the most vulnerable to damage. For this reason, strengthening treatment is adopted at the tiger's mouth of PU gloves. At present, the tiger's mouth is mainly strengthened by sewing leather at the tiger's mouth and coating nitrile rubber on the tiger's crotch. Sewn leather at the tiger's mouth makes the glove's tiger's mouth hard and thick, but it is not flexible during use, and it needs to be sewn one by one with a sewing machine during production, which is low in production efficiency and takes a long time. Nitrile rubber gloves are applied on the tiger's butt, and the glu...
