A kind of hydroxyl-modified petroleum resin applied to naval vessel coating and its production process

Abstract

The invention discloses a hydroxyl-modified petroleum resin applied to ship coatings and a production process thereof, comprising the following steps: S4, fractionating, thermally polymerizing, flashing and molding crude oil through a three-stage reaction tower to obtain hydroxyl groups Modified petroleum resin; the present invention implements fusion treatment by synchronously transporting sulfolane solvent, so that the crude oil can effectively remove residues before being subjected to fractionation, thermal polymerization, flash evaporation and molding processing to obtain hydroxyl-modified petroleum resin raw materials in a three-stage reaction tower. benzene, so that users can effectively avoid the pollution of toxic substances when mass-producing the hydroxy-modified petroleum resin, thereby effectively improving the utilization rate of the hydroxy-modified petroleum resin. It makes up for the situation that the ship's coating in the traditional method loses its protective effect due to long-term seawater erosion, thereby effectively improving the corrosion resistance of ships immersed in seawater for a long time.

Description

technical field [0001] The invention relates to the technical field of petroleum resins, in particular to a hydroxy-modified petroleum resin used for ship coatings and a production process thereof. Background technique [0002] Ships, commonly known as warships, also known as naval ships, refer to naval vessels with weapons and equipment that can perform combat missions in the ocean. They are the main equipment of the navy. Ships are regarded as part of the national territory and only abide by the laws of their own countries and recognized international laws. Ships are mainly used for maritime maneuver operations, conducting strategic nuclear raids, protecting one's own side or destroying enemy's sea lines of communication, conducting blockade or anti-blockade, participating in landing or anti-landing operations, and undertaking maritime supply, transportation, repair, lifesaving, medical treatment, Support services such as reconnaissance, survey, measurement, engineering an...

Problems solved by technology

[0003] Traditional ship coatings are prone to corrosion and peeling off when the ship is immersed in seawater for a long time, so that the inner steel plate of the ship is exposed to the external sea water and is extremely vulnerable to intrusion corrosion, which seriously affects the ship's nautical life, so it is difficult to Meet the needs of existing technology
