Abstract
The invention discloses solvent-free epoxy/diamond grain re-coating anti-corrosive paint which comprises epoxy resin and a modified ammonia curing agent. The re-coating anti-corrosive paint is characterized by further comprising diamond grain, an antifoaming agent, a defoaming agent and a modified castor oil thixotropic agent. The application of the solvent-free epoxy/diamond grain re-coating anti-corrosive paint disclosed by the invention can increase the production efficiency by more than 50 percent and increase the service life of an oil delivery pipe up to more than five years, and is environmentally-friendly.
Description
Technical field
The present invention relates to a kind of protective system, be specifically related to a kind of protective system for the oil pipeline inwall.
Background technology
Now, in oil pipeline inner wall anti-corrosive field of coating, mostly adopt artificial brushing, the thickest 0.15mm that is no more than of per pass brushing, as reach 2-4mm thickness and must carry out the multiple tracks brushing, the expense of taking a lot of work material, and existing oil pipeline inner surface anticorrosion paint generally all contains volatile diluent, not environmental protection.
Summary of the invention
In order to improve painting efficiency, strengthen environmental protection, to improve transition pipeline work-ing life, the invention provides a kind of solvent-free transition pipeline protective system, it comprises Resins, epoxy and modification Ammonia solidifying agent, characterized by further comprising silicon carbide, defoamer, deaerating agent and modified castor oils thixotropic agent.
Preferably, described Resins, epoxy is liquid 128 Resins, epoxy.
Preferably, described defoamer and deaerating agent are selected respectively EFKA-2722 and EFKA-3239.
Preferably, described Resins, epoxy and modification Ammonia solidifying agent weight proportion relation are 100: 100.
Preferably, described silicon carbide adding proportion is not less than 35% of prescription gross weight.
Preferably, the weight content of Resins, epoxy, modification Ammonia solidifying agent, silicon carbide, defoamer EFKA-2722, deaerating agent EFKA-3239 and modified castor oils thixotropic agent is respectively: 25.75-32.15%, 25.75-32.15%, 35-45%, 0.1-1%, 0.1-1%, 0.5-1.5%.
The present invention also provides a kind of oil pipeline coating process, it is characterized in that comprising the steps: to choose according to the solvent-free protective system for the oil pipeline inwall of the present invention; Oil pipeline is brushed, and wherein disposable film thickness reaches more than the 2mm; Dry coating under field conditions (factors) or in the baking oven.
Because existing pipeline inner wall anticorrosion paint mostly is the solvent-borne type product, the per pass brushing can not surpass 150 microns, otherwise is easy to occur sagging, and is dry bad, bubbles the disadvantages such as cracking.As brush 2-4mm and need to construct 14 times to 26 times, cost of labor and duration property are very high; Non-solvent epoxy Buddha's warrior attendant provided by the present invention heavily plates protective system, must drive the raising of production efficiency, can enhance productivity more than 50%, and can improve transition pipeline working life more than 5 years.
Embodiment
Selecting Resins, epoxy and modification Ammonia solidifying agent is main film forming matter, can guarantee to have good application property under the state that does not add volatile diluent (solvent), and acidproof, alkaline-resisting, wear-resistant etc.Selecting silicon carbide is main wear-resistant medium, replaces common quartz sand.Silicon carbide Mohs' hardness 10, quartz sand Mohs' hardness 7 can improve the finished product wear resistance more than 30%.Reach more than the 2mm in order to be implemented in disposable film thickness, time of drying, within 50 minutes, the present invention adopted high effective antifoaming agent to be equipped with deaerating agent to the product froth breaking again; Put into 50 degrees centigrade of baking ovens baking 40 minutes after the making sheet, observe the test plate (panel) condition of surface, coating surface is without bubble, free of pinholes.Also be added with modified castor oils thixotropic agent in the coating, form three-dimensional netted system after the high speed dispersion, sagging problem in sedimentation problem and the construction process in the solution storage process
In a preferred implementation, defoamer and deaerating agent (flow agent) are selected respectively EFKA-2722 and EFKA-3239.
