Problems solved by technology

[0003] 1. Some of the existing glove finishing products add some fillers such as micron-sized wax powder or white carbon black. Fillers that do not belong to the same system are easy to layer and precipitate during preparation, and the matting effect and smoothness of the film are not good.
[0004] 2. Gloves will be sweaty, sticky and stuffy after wearing, and it is not easy to put on and take off
User comfort / anti-sensitivity is not considered in the published literature
[0005] 3. After the gloves are baked at about 180°C, they cannot be impregnated with water-based polyurethane coating agents at high temperatures. They need to be cooled to 70°C before they can be impregnated. The process consumes energy

Abstract

The invention discloses a powderless super-smooth water-based polyurethane coating agent for gloves and a preparation method thereof. The coating agent is prepared from water-based polyurethane, water-based polyacrylic resin, polyurethane granules, wetting agent, thickening agent, anti-sticking slipping defoaming agent and deionized water. The water-based polyurethane is prepared from polyalcohol, aliphatic diisocyanate, ionizing reagent, chain extender, environment-friendly solvent, neutralizer and deionized water. The water-based polyurethane (PU) is added into the polyurethane granules (PU granules) to produce surface roughness and fuzz sensation, so that the water-based polyurethane coating agent is soft and smooth, can not easily fall off after people wear the gloves, can not easily generate peculiar smell and stimulation due to perspiration, and has favorable adhesive force of PVC (polyvinyl chloride).

Description

technical field [0001] The invention relates to a super-smooth water-based polyurethane finishing agent for powder-free gloves and a preparation method thereof. Background technique [0002] Most of the existing plastic gloves are made of PVC, natural rubber, nitrile rubber (NBR) and other materials. However, due to the stickiness and airtightness of these materials, gloves made of these materials are prone to sticking. To improve the adhesion between the inner surface of the glove and the hand, the surface of the glove is usually treated with a coating agent to form a thin film on the surface of the glove to prevent adhesion. This kind of glove is called a powder-free glove. Existing finishing agents generally have the following disadvantages: [0003] 1. Some of the existing glove finishing products add some fillers such as micron-sized wax powder or white carbon black. Fillers that do not belong to the same system are easy to layer and precipitate during preparation, and...
