Problems solved by technology

Most of the heat is concentrated on the surface of the oil interface, which accelerates the evaporation of the oil, causes "breathing" loss, and increases the pressure in the tank, which is not conducive to safe and stable production, and the exhaust increases the environmental burden.
In order to ensure the safety of storage tanks, the method of spraying is usually used to reduce the temperature, which not only requires external power supply, wastes manpower, material resources and financial resources, but also the coating is difficult to withstand the erosion of water, and the alternating dry and wet environment makes it prematurely aging and corrosive facilities

Abstract

The invention discloses a heat-reflecting thermal insulation coating which is characterized by comprising the following ingredients by weight: 15 to 30 parts of epoxy resin, 10 to 40 parts of a filler, 0.1 to 7 parts of an additive and 1 to 15 parts of a curing agent. The heat-reflecting thermal insulation coating is a novel material changing the conventional thermal insulation manner, not only is anti-corrosion, but also can effectively insulate an object from sunlight infrared radiation heat under the condition that the coating is only 1 mm thick, and has the advantages that the temperature difference between the wall of a tank and a liquid in the tank can be 7 to 12 DEG C, and the temperature of the storage tank can be further lowered by 3 to 8 degrees compared with the condition that the storage tank is treated according to the conventional water spraying method.

Description

technical field [0001] The invention relates to a heat-reflecting heat-insulating coating and a chemical product storage tank. Background technique [0002] Chemical products, especially petrochemical product storage tanks have the characteristics of large storage capacity and flammable and explosive storage media. Petrochemical products such as liquefied petroleum gas stored in petrochemical product storage tanks are flammable, explosive, and volatile products. These factors determine that liquid petrochemical product storage tanks must be sealed, anti-corrosion, and necessary cooling measures must be taken. According to the provisions of GB11174-89 "Liquefied Petroleum Gas Storage, Transportation, Acceptance and Measurement Regulations", the surface temperature of liquefied petroleum gas balloon tanks, light oil tanks, and chemical light low-boiling substance storage tanks in summer should not exceed 50°C. The area does not exceed 45°C. [0003] Due to long-term outdoor ...
