Problems solved by technology

[0005] However, the barrier explosion-proof materials applicable in our country now have the following problems: 1) The barrier explosion-proof materials used for filling oil tanks and oil tanks on the market will not affect the performance of oil products (octane number) and oil deterioration tendency (acidity) It will cause obvious impact, but it will significantly affect the storage performance of the oil (actual colloid, induction period and oxidation stability headquarters solution), and it will cause pollution to the oil, which is reflected in the accumulation of metals produced by friction and wear in the oil storage container Debris, and increased levels of particulate contamination and metal ions in oil
2) At present, the filling density and replacement rate of the latest non-metallic barrier explosion-proof materials are too high, making the production cost high
3) The resistivity of the conductive coating on oil tanks increases with time (10 12 Ω), poor stability, and the resistivity of this type of coating must be controlled at no more than 10 9 Ω, so it needs to be recoated to avoid electrostatic fire and explosion accidents caused by a sharp drop in electrostatic potential
4) Static conductive coatings have limited anti-corrosion ability and poor environmental adaptability
Because the surfactant in the second category will continue to lose into the petroleum products soaked in the coating surface, the conductivity of the coating will decline sharply and lose the antistatic function; the deposition system of the third category is for the inner wall of the storage tank. process implementation is not possible

Abstract

The invention discloses a carbon nanostructure reinforced explosion-proof surface material which is excellent in barrier explosion-proof performance and can be industrially produced, and a preparationmethod thereof, and particularly discloses a carbon material (such as graphene) reinforced epoxy powder paint and preparation method thereof. The paint is characterized by comprising 2 to 5wt per thousand of carbon nanometer material. According to the paint, a modified carbon material is added in a specific silane epoxy additive, an additive material is sufficiently refined through a tertiary grinding and dispersion technology, carbon material is intensively dispersed, an epoxy powder paint finished product is obtained through traditional technologies of crushing and sieving, and reinforced explosion-proof barrier powder paints with different trace contents and ratios are sufficiently prepared. The paint belongs to special coating developed for an HAN (Hypostasis Anch Noexplosion) barrierexplosion-proof technology, can effectively prevent explosion of inflammable, explosive, gaseous and liquid dangerous chemicals caused by fortuitous accidents (such as static electricity, welding, shooting, collision and faulty operation) during storage and transportation, and thoroughly solves the intrinsic safety problem of the inflammable, explosive, liquid and gaseous dangerous chemicals during storage and transportation. The high-performance explosion-proof paint can be widely applied to military products and military and civilian products, such as vehicle manufacture, military vehicle armor, military helmets and building curtain walls.

Description

technical field [0001] The invention discloses an industrially produced carbon nanostructure reinforced epoxy explosion-proof surface material with good barrier and explosion-proof performance and a preparation method thereof, in particular a graphene-enhanced coating and a preparation method thereof. Background technique [0002] As a kind of important people's livelihood and strategic materials, the safety of oil has always been the focus of people's attention. For example, in the field of public transportation, in recent years, various types of domestic vehicles have experienced frequent combustion and explosion incidents caused by traffic accidents and spontaneous combustion, which have caused huge losses of life and property, and brought social instability. In the process of transportation and use, a large number of casualties and property losses of more than three billion yuan are caused by burning and explosions in accidents every year. In the field of dangerous good...
