Description
Technical Field
The invention belongs to the field of coatings, and particularly relates to a ceramic anticorrosive wear-resistant bi-component epoxy resin coating containing a flexible high-molecular dispersing agent, in particular to a coating applied to petroleum pipelines and ship decks and needing anticorrosive wear-resistant fields.
Background
Coatings are an important metal protection measure. The general coating is composed of resin, filler, assistant and solvent. The special coating can be a powder coating without solvent. However, whatever the type of coating, the most important properties that determine the coating are resins and fillers. This means that changing the resin and filler can change the properties of the coating.
With the change of the using environment, more requirements are made on the performance of the coating, and the coating not only has a general corrosion protection effect on metal, but also requires some special functions. For example: wear resistance, etc. to meet the special requirements of some occasions. For example, transporting fine sand containing pipeline, ship deck, grinding machine and other coating materials.
In an abrasive, corrosive environment, the coating is subjected to stresses caused by friction and corrosion. The coating fails due to abrasion, and meanwhile, the stress cannot be timely released, so that the aging of the coating is accelerated, the metal protection time of the coating is shortened, the maintenance cost is increased, and further the equipment is more damaged due to corrosion.
In order to satisfy the use of the coating in the abrasive and corrosive environments, the resin or filler, or both, needs to be changed from the compositional analysis of the coating to accommodate its use in the abrasive and corrosive environments.
Among the used coatings, epoxy resins are the most important anticorrosive coatings. The epoxy resin includes bisphenol A epoxy resin, bisphenol F epoxy resin, novolac epoxy resin and the like.
The phenolic epoxy resin has the advantages of high hardness, high temperature resistance, acid and alkali resistance and wear resistance.
The bisphenol A epoxy resin has the characteristics of low viscosity, stress release and the like.
The bisphenol F epoxy resin has good flexibility, low viscosity and quick response to external stress.
The use of different epoxy resins is inherently a stress relief method, but neither use nor control is convenient.
The rubber has elasticity, so that the rubber can better adapt to the change of the external environmental stress. The compatibility of the rubber with the epoxy makes it susceptible to delamination during curing.
Stress is generated by external forces or curing of the coating, and if the stress-generating coating is not released in a timely and effective manner, it remains in the coating and will accelerate failure of the coating. There are numerous experimental data that show: the stress is also closely related to the structure, type and chain length of the dispersant.
During the erosion of the coating, the fillers in the coating greatly affect the wear resistance of the coating. Especially the synergistic effect of the combination and collocation of different fillers affects the abrasion of the coating. In the prior patents and literature, the use of coatings to improve abrasion resistance has been reported. For example patent CN 104130662A. But these only take into account their filling properties and neglect the effect between the filler and the resin.
Meanwhile, the hardness and elasticity of the resin itself also affect the wear resistance. In general, the higher the coating hardness, the better the abrasion resistance; the greater the elasticity, the better the wear resistance. Based on this basic understanding, efforts are being made to design wear and corrosion resistant coatings.
In the prior wear-resistant paint, people usually pay attention to the flexibility of the coating, and a polyurethane coating is mostly selected. However, in terms of corrosion resistance, polyurethane coatings have a certain gap compared with epoxy resins, and designing epoxy resins into a wear-resistant and corrosion-resistant coating is an important problem to be solved.

wherein n is 10-20, R is alkyl, and the number of carbon atoms is 1-5. The reaction temperature is 100 ℃, and the reaction time is 4 h.
