Abstract

The invention relates to the field of an adhesive, in particular to water-based neoprene with storage stability. The water-based neoprene is prepared from 0.5 to 2 weight percent of lithium salt and 1to 2 weight percent of anion complex. The invention aims at providing the water-based neoprene with high storage stability. Meanwhile, the invention also discloses a storage method of the water-basedneoprene.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a storage-stable water-based neoprene and a storage method for the water-based neoprene. Background technique [0002] Since water-based neoprene latex uses water as a carrier, there is no solvent emission, it is environmentally friendly, safe and reliable for storage and transportation, and has no odor. It has replaced some solvent-based neoprene and is widely used in mattresses, sofas, and bags. , wood industry, shoe industry, automobile, etc. [0003] At present, foreign German companies and Japanese companies have produced water-based neoprene for sale in the market, and domestic Shanna Company has also put some water-based neoprene products on the market. Because the pH value of water-based neoprene latex will drop slowly, it will directly affect the stability of the latex, causing the latex to break and coagulate. The shelf life of water-based neoprene latex of general ma...
