Abstract
The invention discloses high temperature resistant nitrile rubber latex for a lined glove and a preparation method thereof. The high temperature resistant nitrile rubber latex for the lined glove is prepared from the following raw materials in parts by weight: 90 to 100 parts of butadiene, 45 to 55 parts of acrylonitrile, 6 to 9 parts of methylsuccinic acid, 5 to 8 parts of 2-ethylhexyl acrylate, 1 to 2 parts of potassium hydrogen phosphate, 0.6 to 0.8 part of sodium carbonate, 2 to 3 parts of N,N-dimethylaniline, 1 to 2 parts of a molecular weight regulator, 1 to 2 parts of tetramethylthiourea, 2 to 4 parts of polyacrylamide and the like. The nitrile rubber latex used for the glove disclosed by the invention has the characteristics of high wet gel strength, low shrinkage and the like, so that the nitrile rubber latex is suitable for making a dipped article. Because of added light calcined powder and aluminium dihydrogen tripolyphosphate, the high temperature resistance of a product can be improved, and the product can be prevented from being damaged and has a very good heat insulating effect. The film-forming property of the rubber latex is improved and the strength of a vulcanized film is reinforced due to the added glyceryl monostearate and magnesium stearate.
