High solid content PVC glove powder-free aqueous coating and its preparation method and use method

Abstract

The invention discloses a high solid content PVC glove powder-free aqueous coating. The high solid content PVC glove powder-free aqueous coating comprises 30-40wt% of a delustering agent, 15-25wt% of a wetting levelling agent, 15-25wt% of water-soluble resin, 20-30wt% of redispersible polyurethane resin, 0.2-0.5wt% of a solid thickening agent and 1.5-10wt% of water. The preparation method comprises uniformly dispersing and mixing a wetting levelling agent and an inorganic delustering agent, mixing the mixture and an organic delustering agent, carrying out uniform mixing, uniformly mixing the mixture, redispersible polyurethane resin, water-soluble resin and a solid thickening agent and packaging and storing the mixture. The invention discloses the use method of the high solid content PVC glove powder-free aqueous coating. The high solid content PVC glove powder-free aqueous coating solves the prior art problems, has high solid content, large dilution multiple and a low transport cost and can be simply fed.

Description

technical field [0001] The invention relates to the technical field of PVC gloves processing, in particular to a powder-free water-based coating for PVC gloves with a high solid content and a preparation and use method thereof. Background technique [0002] PVC gloves occupy an important position in the market because they are cheaper than nitrile gloves, latex gloves, and polyurethane gloves, and have good protective performance. Since PVC gloves contain a large amount of plasticizers, the gloves are easy to stick back during storage and transportation, which affects the performance of wearing and using. In order to solve this problem, during the production process of gloves, there will be a dip coating process, and a coating is applied to the inside of the glove to play the role of easy release, anti-adhesion, and improved wearability. There are mainly two processing methods in current production. One is to use cross-linked starch to produce powdered gloves. The gloves ar...

Problems solved by technology

There are mainly two processing methods in current production. One is to use cross-linked starch to produce powdered gloves. The gloves are very smooth to wear. The disadvantage is that it is easy to get powder on the hands, prone to allergies, and the production line has been used for a long time. It will breed bacteria and produce odor; one is to use powder-free PVC coating agent for finishing, the mainstream market is to use water-based polyurethane coating, most of the solid content ranges between 12-35%, for example, the solid content of Japanese products is 30% -33%, it can be diluted 30-35 times when used; the solid content of products from Taiwan, China Beijing Youmeite, Shanghai Zhengfeng, Anhui Lingda and other companies are all lower than 35%, and the moisture content accounts for more than 60%.
