Diesel tail gas treating fluid storage tank and manufacturing method thereof

Abstract

The invention belongs to the technical field of oil tanks and discloses a diesel tail gas treating fluid storage tank and a manufacturing method thereof. The tank is characterized by being formed by an inner tank body made of glass fiber reinforced plastics, an outer tank body made of glass fiber reinforced plastics and a hollow layer formed by a continuous cavity formed between the inner tank body and the outer tank body. The inner tank body comprises a resin layer and an inner function layer formed by resin and organic fiber. Resin in the resin layer and the inner function layer is formed by a curing system formed by vinyl ester resin, benzoyl peroxide and N,N-dimethylaniline. Due to the fact that the inner tank body overcomes metal ion precipitation, the metal ions are effectively prevented from being mixed with the diesel tail gas treating fluid, and storage of the diesel tail gas treating fluid is facilitated. The storage tank is formed by the inner tank body, the hollow layer, the outer tank body and a reinforced rib structure, seepage proof capacity is improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of oil storage tanks, and in particular relates to a storage tank for diesel tail gas treatment liquid with a double-wall structure and a preparation method thereof. Background technique [0002] Diesel vehicle exhaust treatment fluid is a highly refined chemical product. During storage and transportation, metal ions such as aluminum, calcium, iron, copper and other organic substances must not be mixed, otherwise the treatment effect on vehicle exhaust will be greatly reduced. . At present, stainless steel tanks are used to store diesel exhaust treatment fluid, and only 10L / barrel and 20L / barrel stainless steel barrels can be used for retail supply in barrels. However, these stainless steel tanks or barrels are Welded stainless steel plate. However, the welds of the tank or barrel will produce intergranular corrosion and liquid leakage during long-term use; therefore, the stainless steel tank or barrel has...

[0003] China Patent No. 201010298344.7, application publication number CN101948038A patent application for invention discloses a FRP double-wall oil storage tank and its preparation method and special mold, and the inner tank body constituting the structure of the FRP double-wall oil storage tank is "in place Lay a layer of cloth layer dipped in resin on the above hollow layer, and then coat resin and chopped fibers on the cloth layer, and roll it to form”, the inner tank body of this structure is difficult to ensure its The strength of chopped fibers makes the inner tank body not only difficult to meet the storage of diesel vehicle exhaust treatment fluid in terms of structural strength, but also the inner tank body prepared by using the conventional curing system composed of methyl ethyl ketone peroxide / cobalt salt , because it is very easy to precipitate dangerous metal ions, it is impossible to make the oil storage tank meet the storage of diesel vehicle exhaust treatment fluid
