The invention relates to three watercrafts self-viscosity latex product with superior cold tolerance, and its usage. Meanwhile, it offers a manufacturing method of cold tolerance self-viscosity latex product, which can be described as follows: dissolve xylene denatured resin, rosin denatured resin, natural rubber, or synthetic rubber, in order to change its oiliness into watercrafts, and then make it have emulsification and dispersion. One feature of the invention lies in the use of a kind of reactivity emulsifier that can take combined polymerization reaction with monomer; another feature lies in that it acquires the cold tolerance by dissolving xylene denatured resin, rosin denatured resin, natural rubber, or synthetic rubber, in order to change its oiliness into watercrafts, and by making it have emulsification and dispersion. The cold tolerance self-viscosity latex has the advantages such as initial adhesion, high adhesion in winter, fine water resistance, low cost, no evocative fire hazard, more safety, better environmental protection, better guarantee of worker's health, so it can substitute oiliness rubber and solvent form Alec Rubber completely.
