The invention discloses carboxylic butadiene-vinylpyridine latex as well as a preparation method and application thereof. The carboxylic butadiene-vinylpyridine latex is prepared from the following components in parts by weight: 65 to 75 parts of butadiene, 10 to 15 parts of 2-vinylpyridine, 10 to 15 parts of propyl ethylene, 10 to 15 parts of acrylic acid, 10 to 15 parts of itaconic acid BD, 1 to 5 parts of maleic anhydride, 0.1 to 1.5 parts of an emulsifier, 0.5 to 1.0 part of a molecular weight regulator and 0.1 to 0.5 part of an initiator. According to the carboxylic butadiene-vinylpyridine latex provided by the invention, a main body adopts butadiene, propyl ethylene, acrylic acid, itaconic acid BD and 2-vinylpyridine, then deionized water, a conditioning agent, maleic anhydride and the like are added, polyoxyethylene lauryl ether, nekal, sodium dodecyl sulfate and the like are used as emulsifiers, mercaptan is used as a conditioning agent, and the carboxylic butadiene-vinylpyridine latex is prepared by a one-step method. And a proper amount of carboxyl monomer is supplemented to improve the product performance, such as the heat resistance, aging resistance, fatigue resistance and the like of the curtain canvas.
