Non-powder treating agent for gloves made of latex

Abstract

The invention relates to a powder-free treatment agent used for latex gloves, which pertains to the field of chemical products. The invention mainly resolves the coating raw materials used in the latex glove coating process. The invention replaces the treatment agent of anionic water-base resin system in the prior art with the treatment agent of cationic water-base resin system. The cationic water-base resin prefers 10 to 90 parts of cationic water-base polyurethane resin and cationic water-base acrylic resin, 0 to 70 parts of paraffin oil, 1 to 80 parts of wax powder and 0.1 to 10 parts of silicone oil which are mixed for uniform and complete stirring. The powder-free treatment agent has the advantages of good coating quality for the latex gloves, strong binding between the coating and the latex glove surface, uneasy to flake off as well as excellent smoothness property and anti-blocking property. The invention also has high weather resistance for polyvalent metal cations as well as hard-water resistance. When being applied in coating process, the emulsion of the invention is not easy to break and gelatinize to produce sediment, thus greatly improving coating quality and production efficiency, saving raw materials and reducing cost.

Description

technical field [0001] The invention belongs to the field of chemicals and relates to a powder-free treatment agent for latex gloves. Background technique [0002] At present, the surface treatment process of latex gloves includes: chlorine washing, dipping in silicone oil emulsion, spraying corresponding micro-materials and coating, except for coating process, other treatment processes are not easy to operate, low production efficiency, low quality, toxic and harmful substances Residues and emissions are serious, and it is difficult to meet environmental protection requirements. The coating treatment process is not only easy to operate, stable in quality, high in production efficiency, but also very conducive to environmental protection. However, the powder-free treatment agent used in the existing coating process—that is, coating The raw material is generally anionic water-based acrylic resin or anionic water-based polyurethane system.

[0002] At present, the surface treatment process of latex gloves includes: chlorine washing, dipping in silicone oil emulsion, spraying corresponding micro-materials and coating, except for coating process, other treatment processes are not easy to operate, low production efficiency, low quality, toxic and harmful substances Residues and emissions are serious, and it is difficult to meet environmental protection requirements. The coating treatment process is not only easy to operate, stable in quality, high in production efficiency, but also very conducive to environmental protection. However, the powder-free treatment agent used in the existing coating process—that is, coating The raw material is generally anionic water-based acrylic resin or anionic water-based polyurethane system. This kind of coating material has poor adhesion to the surface of latex gloves and is easy to fall off, which affects the quality and use of gloves. At the same time, because the coating process is in the coating The aqueous solution of the raw material is treated in the tank, and the aqueous solution of the coating raw material used in the production is made of ordinary water, which contains a large amount of multivalent metal cations, such as calcium and magnesium ions, which are easy to cause demulsification of the anionic water-based resin system. And coagulation, and sediment deposits in the treatment tank, which not only affects the quality of the coating, wastes raw materials, but also requires frequent cleaning of the treatment tank, increasing unnecessary labor
