Problems solved by technology

[0003] The boiler will be affected by various factors such as temperature, water, and air when it is working. If things go on like this, it will be easily corroded. Therefore, it is necessary to protect the surface of the boiler. However, after the existing coating is applied to the outer surface of the boiler, due to the temperature Elevation and water contact erosion will easily lead to cracking and peeling off of the coating film, greatly reducing its service life
[0004] The publication number is "CN 106987204 A", an epoxy-modified organosilicon heat-resistant coating and its preparation method. Mechanical properties, so that the protected object can still function normally in a high temperature environment; it does not disclose how much high temperature it can withstand, and at the same time, the heat-resistant coating it prepares also has certain shortcomings. The temperature resistance performance is not good, and the film quality is average

Abstract

The invention discloses a boiler exterior wall coating with high temperature resistance and high film formation quality, and relates to the technical field of boiler coating. 0.5 wt%-2.2 wt% of carboxymethylated cellulose nanofibers and 3.5 wt%-6.8 wt% of a water-soluble acrylamide polymer composition are added into a resin matrix. After being sprayed on the surface of a boiler, the prepared boiler exterior wall coating with high temperature resistance and high film formation quality has good solidification effect on the boiler, can effectively protect the boiler, and has good heat resistanceand wear resistance.

Description

technical field [0001] The invention belongs to the technical field of boiler coatings, in particular to a boiler outer wall coating with high temperature resistance and high film-forming quality. Background technique [0002] Paint, traditionally known as paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] The boiler will be affected by various factors such as temperature, water, and air when it is working. If things go on like this, it will be easily corroded. Therefore, it is necessary to protect the surface of the boiler. However, after the existing coating is applied to the outer surface of the boiler, due to the temperature Elevation and water contact eros...
