Thermal insulation and weather-resistant coating, preparation method and application thereof

Abstract

The invention provides a thermal insulation and weather-resistant coating, a preparation method and application thereof, and relates to the technical field of coatings. The coating comprises raw materials in parts by mass: 20-30 parts of heat radiation fillers and 10-20 parts of heat reflection fillers , 10-20 parts of thermal insulation filler, 20-30 parts of polymer emulsion, 0-5 parts of auxiliary agent, and water supplemented to 100 parts; wherein, the heat radiation filler includes cobalt phosphate and 12-sodium molybdenum heterosilicate, And the mass ratio of the two is (2‑3):(3‑2). In the present invention, cobalt phosphate and 12-sodium molybdenum heterosilicate are used as heat radiation fillers, in coordination with heat reflection fillers, thermal insulation fillers and polymer emulsions, and the obtained coating is coated on the surfaces of equipment and pipes, which can not only effectively isolate infrared radiation , has infrared reflection effect, and can effectively reduce heat conduction, improve thermal insulation performance, and also has excellent weather resistance, which can effectively prolong the service life of equipment and pipes.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermal insulation and weather-resistant coating and a preparation method and application thereof. Background technique [0002] In the process of oilfield extraction, in order to meet the production process conditions and meet the needs of crude oil extraction and transportation, it is necessary to actively provide heat source heating and heat preservation to the equipment and pipelines in the oil production well to maintain a certain temperature to meet the needs of the process and equipment. operating temperature required. At present, the associated parts such as pipelines and equipment in the oil production well are generally heated and insulated by means of electric heat tracing, while the existing electric heat tracing method is to directly wind the heating wire for heating, and then wrap it with glass fiber cloth for heat preservation. The glass fiber cloth is blown by ...
