Abstract

The invention discloses car tail gas detecting equipment. The car tail gas detecting equipment comprises a metal shell subjected to coating treatment. The coating treatment includes the steps of firstly, sequentially adding 1-2 parts of sebacic acid, 1.5 parts of sodium metasilicate, 2.2 parts of vinyl trimethoxy silane and 1.4 parts of alkyl naphthalene sulfonate into 48 parts of deionized water, and evenly stirring; secondly, sequentially adding 12.5 parts of diethylhexyl carbonate, 11.1 parts of ethyl acrylate, 1.3 parts of dodecyl betaine and 0.7 part of benzotriazole, and continuing stirring until the materials are sufficiently evenly mixed to obtain coating treatment liquid; thirdly, impregnating the metal shell in the coating treatment liquid, and taking out and drying. The car tail gas detecting equipment has the advantages that the metal shell of the car tail gas detecting equipment is coated with a protecting film and is good in performance and good in surface smoothness.

Description
