Description
Technical Field
The invention relates to the technical field of coatings, in particular to a thin film high-temperature nano wear-resistant coating.
Background
At present, the problems of high temperature abrasion resistance exist for metal overflow gas-solid two-phase flow parts in the fields of domestic and foreign electric boilers, cement and coal coking, mainly the inner wall and the outer wall of the metal overflow gas-solid two-phase flow parts are stuck by high temperature abrasion-resistant paint, ceramic sticking blocks, tortoise shell nets and the like with various properties to form high temperature abrasion-resistant isolation layers, but the abrasion resistance and the high temperature resistance are generally not ideal and are easy to fall off in pieces.
The main means of the current abrasion resistance is that the ceramic block and the tortoise shell net are combined with ceramic plastic, the base material to be protected is covered by pasting, the thickness of the base material is up to a certain thickness (generally up to 15-30 mm), the abrasion resistance protective layer is formed, and the high strength and the corrosion resistance characteristics of the ceramic and the ceramic plastic are utilized, so that the base material is protected by abrasion resistance.
Although these two methods are widely used, they have the following disadvantages: the ceramic sticking block must be bonded by using adhesive, once the adhesive fails or the adhesive coated in the construction process is unevenly coated, the adhesive has poor temperature resistance, and the ceramic sticking block can fall off in a piece, so that the large-area wear-resistant protection layer fails. The ceramic plastic of the tortoise shell net is easy to fill unevenly and not compactly in the construction and use process, so that the abrasion-resistant protective layer is loose and difficult to find by naked eyes, the final abrasion-resistant protective layer is loose and falls off in a piece, abrasion-resistant protection is lost, and the later dismantling and maintenance are very difficult and the repair effect is poor due to the grid influence of the tortoise shell net.
The conventional wear resistant coating is widely applied at present, but has the following defects: the wear-resistant particles can enhance the adhesive force of the coating, improve the mechanical strength of the coating, resist abrasion and resist impact, but the content of the wear-resistant particles cannot be high, generally is below 30%, because the content of the wear-resistant particles is high, the problem of precipitation exists, the wear-resistant particles are easy to delaminate in the use process of the coating, the wear-resistant particles cannot be uniformly distributed in the coating, the adhesive force of the coating is reduced, the coating is easy to fall off, the high-temperature wear-resistant quality of the coating is influenced, and in addition, due to the existence of non-flame-retardant high polymer materials, certain specific application occasions are very easy to cause serious safety accidents. The high cost is caused by the high proportion of high polymer materials with high use cost.
