Butyl latex and preparation method thereof as well as preparation method of gloves prepared from butyl latex

Abstract

The invention discloses butyl latex. The butyl latex is prepared from the following raw materials in parts by weight: 100 parts of butyl rubber paste, 11-19 parts of an emulsifier mixture, 13-18 partsof a mixed dispersing system and 0-0.5 part of a stabilizer KOH (potassium hydroxide); the emulsifier mixture is prepared from the following raw materials in parts by weight: 4-6 parts of oleic acid,2-4 parts of the stabilizer KOH, 1-3 parts of potassium dihydrogen phosphate, 2-4 parts of polyvinyl alcohol and 2-4 parts of potassium soap, the potassium soap is prepared from the following raw materials by mass percent: 75-85% of castor oil, 10% of the stabilizer KOH and the balance of an aqueous solution. Solid butyl rubber is prepared into the butyl latex, the emulsifier and the like are added in a preparation process, gel particles or gum residue generated by mechanical action in the preparation process of latex are reduced, the problem that the conversion rate of the butyl latex is lowis solved, the conversion rate of the butyl latex can be increased by 12% or above compared with that of existing butyl latex, the process stability is good in the production process of the gloves, and the prepared gloves have excellent tensile strength.

Description

technical field [0001] The invention belongs to the field of rubber gloves, in particular to a kind of butyl latex and its preparation method and the preparation method of the gloves prepared by it. Background technique [0002] As a main type of synthetic rubber, butyl rubber has the characteristics of heat resistance, ozone resistance, low temperature resistance and high air tightness, and is widely used in the manufacture of gloves, rubber hoses, medical rubber stoppers, tire inner liners and adhesive products. Butyl latex retains the characteristics of butyl rubber, the processing technology is simpler, and it is easy to use with other latex. The dipping and coating process can be used to prepare cord dipping, protective clothing, anti-corrosion coatings and packaging coatings, non-woven fabrics, anti-virus gloves, etc. Butyl latex, polyisoprene latex, and ethylene-propylene latex are collectively known as the three major artificial latexes, and are generally suitable f...
