A kind of preparation method of epoxy heavy-duty anti-corrosion conductive static fireproof coating

Abstract

The invention proposes a preparation method of an epoxy heavy-anticorrosive, electrostatic-conducting and fire-retardant coating. The coating comprises a component A and a component B. The coating is characterized in that the component A comprises the following ingredients: epoxy resin, modified resin, conductive mica powder, rutile titanium dioxide, expansive graphite, antimonous oxide, aluminium hydroxide, ammonium polyphosphate, pentaerythritol, melamine, white vermiculite, organobentonite, a dispersing agent, a flatting agent, a defoamer and a mixed solvent; and the component B comprises the following ingredients: polyamide resin, an assistant and a mixed solvent. The method comprises the following production processes: stirring, dispersing, grinding, proportioning, air drying and curing. The invention relates to a preparation method of a special epoxy heavy-anticorrosive, electrostatic-conducting and fire-retardant coating which is intensively applied to an exterior wall of a storage tank. The coating has special heavy-anticorrosive, electrostatic-conducting and fire-retardant functions, and can be widely applied to high-risk equipment such as a storage tank in chemical industry, and a fire of the storage tank can be effectively prevented and controlled.

Description

technical field [0001] The invention relates to the field of paint preparation, in particular to a preparation method of epoxy heavy-duty anti-corrosion conductive static fireproof paint. Background technique [0002] Although the country has formulated a series of fire prevention measures and policies for storage tanks, there are still many oil tank fires caused by various reasons every year. As far as the first half of 2013 is concerned, on March 22, Shaanxi Shenmu Chemical A fire broke out in an oil storage tank, causing two oil tanks to catch fire; 7 days later (March 29), an oil tank fire occurred in Haoliheng Petrochemical in Qingzhou City, Shandong Province, resulting in one missing and one seriously injured; on June 2, Dalian Petrochemical Co., Ltd. Canister No. 939 in the workshop caught fire, causing two injuries and two missing. In order to prevent and control the storage tank fire and the loss after the fire, it has become the focus of the chemical industry. ...
