An inner wall coating layer (3) and an outer wall coating layer (1) are respectively and tightly compounded on the inner surface and the outer surface of a drilling rod pipe wall (2). The utility model is characterized in that the inner wall coating layer (3) sequentially consists of an inner wall bottom coating layer (3.1), an inner wall middle coating layer (3.2) and an inner wall surface coating layer (3.3) from inside to outside, and the outer wall coating layer (1) sequentially consists of an outer wall bottom coating layer (1.1), an outer wall middle coating layer (1.2) and an outer wall surface coating layer (1.3) from inside to outside. The drilling rod coating layer structure of the utility model has the advantages of good anticorrosion performance and abrasion resistance performance of the inner surface and good anticorrosion performance and weather resistance performance of the outer surface, and can meet the transportation and use requirements.
Description
(1) technical field
The utility model relates to a kind of drilling rod coating structure.Belong to the surface protection technique field.
(2) background technology
Oil drill rocker has higher requirement because its environment for use is more abominable to the protection on its surface.For the external surface of oil drill rocker, require corrosion-resistant in its storage and transportation process, good weatherability; For the inner surface of oil drill rocker, because environment for use requires it to have higher Corrosion Protection and anti-wear performance.Before the utility model was made, common rustproof paint was adopted in the surface protection one of oil drill rocker, is difficult to satisfy the demand of transportation, use, thereby has shortened the application life of oil drill rocker.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of inner surface Corrosion Protection and anti-wear performance good, and corrosion-resistant, the good weatherability of external surface can satisfy the transportation and the drilling rod coating structure of user demand.
The purpose of this utility model is achieved in that a kind of drilling rod coating structure, described drilling rod tube wall closely is compounded with inside coating and outer wall coating respectively on the inside and outside surface, it is characterized in that described inside coating is followed successively by inwall scratch coat, inwall floating coat and internal face coating from inside to outside; Described outer wall coating is followed successively by outer wall scratch coat, outer wall floating coat and outside wall surface coating from inside to outside.
The utility model drilling rod coating structure, described inwall scratch coat is a trbasic zinc phosphate modified epoxy phenolic coating layer, described inwall floating coat is to be the epoxy-phenol resin paint layer of rustproofing pigment with the sheet mica iron oxide, described internal face coating is an epoxy resin modification epoxy-phenol resin paint layer, described outer wall scratch coat is the Zinc phosphate coating layer, described outer wall floating coat is for being the dope layer of rustproofing pigment with the flake aluminum, and described outside wall surface coating is the acrylic resin modified dope layer of organic siliconresin.
The beneficial effect of the utility model drilling rod coating structure is:
Described inside coating cost performance is excellent, the coating storage stability is good, be difficult for precipitation; Application property is good, and sag resistance is strong; Film smooth, antiseptic property good, has that coating adhesion is strong, nontoxic, environmental protection.The coating that described inside coating uses is a kind of coating of novel environment friendly, amount of solid content height (〉=90%), easy construction; Have excellent Corrosion Protection, in the corrosive environment of harshness, use; Have excellent anti-wear energy, in the friction serious environmental, use; Have the excellent flexibility energy, resist various mechanical stress effects and not damaged; Can effectively improve flowability, reduce pump pressure and alleviate wearing and tearing; The most excellent coating in the drilling rod series coating, abrasion resistance and mechanical performance are very outstanding.
Described outer wall coating cost performance is excellent, the coating storage stability is good, be difficult for precipitation; Application property is good, and sag resistance is strong; Film smooth, frictional resistance is little, heat resistance good, has the coating surface strong adhesion, weather-proof, antirust, nontoxic, environmental protection.
In sum, the utility model drilling rod coating structure, its inner surface Corrosion Protection and anti-wear performance are good, and corrosion-resistant, the good weatherability of external surface can satisfy transportation and user demand.
