Description

technical field [0001] The invention relates to the technical field of polymer compounds, in particular to a modified potassium titanate whisker / styrene-butadiene latex composite foaming material and a preparation process thereof. Background technique [0002] Carboxylated styrene-butadiene latex is a copolymer produced by emulsion polymerization of butadiene, styrene, a small amount of carboxylic acid and other additives. It is a milky white water dispersion with blue-purple luster. Carboxylated styrene-butadiene latex has a high proportion of bound styrene, high cohesive force and conjunctival strength, good mechanical and chemical stability, good fluidity and storage stability, and large filling capacity. [0003] At present, the reported uses of styrene-butadiene latex mainly include: special latex for cement (Guan Fujia, Li Yunbo, Huang Zhiwen, laboratory research on styrene-butadiene latex cement slurry [J]. Offshore Oil, 2003, 4(23): 83-86), high-speed coating Latex ...
