The application discloses a preparation method of epoxidized styrene-butadiene latex and epoxidized styrene-butadiene rubber and relates to the technical field of styrene-butadiene rubber epoxidation.The preparation method of the epoxidized styrene-butadiene latex uses a sulfonic acid type emulsifier and a non-ionic emulsifier as stabilizers of the styrene-butadiene latex.It is found for the first time that the use of the sulfonic acid type emulsifier and the non-ionic emulsifier as the stabilizers can not only improve the epoxidation rate of the styrene-butadiene rubber but also maintain the stability of the latex system in the process of synthesizing the epoxidized styrene-butadiene rubber.The sulfonic acid type emulsifier as an acidic surfactant can act as a catalyst in the latex epoxidation process, improve the generation efficiency and reaction rate of peroxyformic acid on the surface of the latex particles and rapidly prepare the epoxidized styrene-butadiene rubber.

Peroxyformic acid compositions for removal of biofilm growth and other contaminants and impurities from industrial processing hard surfaces are disclosed. In particular, peroxyformic acid compositions may be dosed on site and / or generated in situ for the reduction and prevention of biofilms on the hard surfaces. Methods of employing the peroxyformic acid compositions for removal of biofilm growth and other impurities such as aldehydes and alcohols from industrial CO2 effluent are also disclosed which beneficially provide ambient biofilm control and break down more rapidly than other peracids, allowing for extended runs between CIP cleaning, including a reduction and / or elimination of cleaning of the scrubbers and other industrial surfaces.
