Abstract

The invention provides water-based PU slurry and a preparation method as well as application thereof. The water-based PU slurry is prepared from the following materials by mass percent: 70 to 79 percent of water-based PU resin, 5 to 10 percent of delustering agent aqueous solution, 0.2 to 2 percent of wear-resistant agent, and 10 to 20 percent of water-soluble thickener. A process for producing water-based PU gloves by using the water-based PU slurry is free of a toxic solvent DMF, safe and environment friendly. The impregnation gloves prepared by dipping a nylon liner with water-based PU can reach European Union EN388 standards of wear-resisting property level 3, cutting resistance level 1, tear resistance level 3 and puncture resistance level 1.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a water-based PU slurry and its preparation method and application. Background technique [0002] PU coated gloves, also known as PU rubberized gloves or PU finger and palm gloves, completely cover the palm part with specially treated polyurethane, which can provide good anti-skid performance and prevent hand sweat and particle pollution in the palm of the human body. . In the traditional production method of PU coated gloves, dimethylformamide (DMF) solvent is used, and DMF has high toxicity. If there is DMF residue in the gloves, it can be absorbed through the skin and respiratory tract after wearing, causing damage to liver function. damage to the health of workers. Therefore, in many other manufacturing fields, DMF content has been strictly controlled, such as automobile manufacturing, leather industry, footwear industry and so on. In addition, the manufacturing ...
