Process for producing aqueous PU foam gloves

Abstract

The invention discloses a process for producing aqueous PU foam gloves, which comprises: impregnating knitted gloves in a resin, wherein the resin comprises 70 to 80 percent of PU resin and 20 to 30 percent of butadiene-acrylonitrile rubber, and based on the mixed volume of the PU resin and the butadiene-acrylonitrile rubber, also comprises 0.5 to2 percent of foaming agent, 0.5 to 2 percent of sodium dodecylsulphonate, 1 to 5 percent of potassium oleate, 1 to 5 percent of thickener and 5 to 20 percent of foam stabilizer, and the resin is foamed mechanically; before impregnating the knitted gloves with the resin, impregnating the knitted gloves with a coagulator to perform pulp spray and homogenate treatment; after impregnating the knitted gloves with the resin, impregnating the knitted gloves with a curing agent to perform pulp spray and homogenate treatment; drying the knitted gloves impregnated with the resin; and washing the knitted gloves impregnated with the resin with water by first soaking the knitted gloves in warm water for 1 to 30 minutes and then rinsing the knitted gloves with warm water for 1 to 30 minutes. The invention also discloses the aqueous PU foam gloves produced by the process for producing the aqueous PU foam gloves and a resin for use in the process for producing the aqueous PU foam gloves.

Description

technical field [0001] The invention relates to a production process of water-based PU foam gloves, in particular to a process for producing water-based PU foam gloves without using dimethylformamide (DMF) solvent. Background technique [0002] The safety protection gloves produced with knitted liner gloves as the base material and impregnated with water-based PU foaming resin have become a new product in PU impregnated gloves due to their safety, environmental protection, waterproof, breathable, and good wear resistance. In recent years, the sales volume in the international market The share keeps rising. However, the production of such PU impregnated gloves requires the use of dimethylformamide (DMF) as a solvent, and DMF has high toxicity. If there is DMF residue in the gloves, it will irritate the skin after wearing; at the same time, due to the use of DMF in production As a solvent, it will affect the health protection of employees. The European Union has determined t...
