Problems solved by technology

Thereby causing various rusts and peelings of construction machinery car bodies, in order to solve the above problems, people improve the anti-corrosion performance of car bodies by spraying coatings on construction machinery shells, but the existing construction machinery coatings have low protective performance and long service life. Short, poor spraying effect, low protection level, easy to fall off

Abstract

A powdery coating for engineering machinery is prepared from the following raw materials in percent by weight: 50% of polyester, 15% of a curing agent, 5% of an auxiliary agent and 30% of a filler. The powdery coating for engineering machinery is capable of performing antirust protection on engineering vehicle body, prolonging the service life of a whole machine, obtaining a smooth uniform saturated coating layer, and improving the appearance quality and the protection degrade of a product. The powdery coating has excellent appearance effect, excellent outdoor durability, firm coating-layer hardness and excellent anticorrosion performance and resistance to various chemical solvents.

Description

technical field [0001] The invention relates to a powder coating for engineering machinery. Background technique [0002] Construction machinery is the machinery that serves the construction of various basic construction projects such as urban and rural areas, railways, highways, port terminals, farmland water conservancy, electric power, metallurgy, mines, sea and air bases. In my country, construction machinery mainly includes: excavation machinery, shovel transportation Machinery, engineering hoisting machinery, road machinery, compaction machinery, piling machinery, reinforced concrete machinery, rock drilling machinery, forklifts, special construction machinery and other 10 categories. The main common construction machinery are: hydraulic excavators, crawler bulldozers, wheel loaders, road rollers, graders, pavers, forklifts and truck cranes. As we all know, construction machinery is a kind of outdoor working machinery. It has been exposed to harsh environments such as ...
