Do you know the epoxy resin in the epoxy floor? Do you know the characteristics of epoxy coatings? Not only that, the use of epoxy flooring in the process of often appear chromatic aberration, do you know why? Is there a problem in the construction process or is it due to the influence of floor coating? Following is an introduction to "factors causing color difference in epoxy flooring and performance analysis of resins". Epoxy resin is very important in epoxy floor coatings, because the film-forming substance of epoxy floor coatings is mainly formed by the reaction of epoxy resin and its curing agent. Here, the epoxy flooring manufacturer gives you a brief introduction of the composition and properties of epoxy resin.
Generally speaking, epoxy resins can be divided into two categories: glycidyl and non-glycidyl. At present, glycidyl ether is mostly used in epoxy floor coatings, such as bisphenol A epoxy resin and linear phenolic epoxy resin, which are one of the two commonly used resins. Among them, bisphenol A epoxy resin belongs to thermoplastic resin with high cost performance and can be cured with a variety of curing agents.
The catalyst reacts to form many kinds of solidified products with excellent properties, which have good technological properties and can be formed at low pressure and room temperature; low shrinkage can ensure that the internal stress is small and cracking is not easy; moreover, the solidified products have high strength, adhesion strength, toughness and heat resistance because of their high molecular cohesion and dense molecular structure.
However, its moisture and heat resistance and weather resistance are poor. In recent years, more and more attention has been paid to the research and development of linear phenolic epoxy resin, which can achieve high crosslinking density after curing, so it is better than bisphenol A epoxy resin in heat resistance, mechanical strength and chemical resistance. This is the introduction of two common epoxy resins. In research and development, we must base on each other. The coordination reaction of epoxy resin and curing agent, as well as their respective molecular characteristics, has been continuously developed to meet the various needs of consumers.
[Analysis of the causes of color difference in epoxy floors]
The colour difference of epoxy floor is also one of the common quality problems of floor. Some floor construction team experience and technology is not good or the quality of floor paint is not good, it is likely to cause the colour difference phenomenon on the surface of well-done floor paint. Here is a brief introduction to the color difference of the lower floor.
The colour difference of epoxy floor is caused by two factors: one is the problem of floor paint, the other is the problem of construction technology. Firstly, it is very possible that the color difference of the floor after construction is caused by the floor coating. If the floor coating is not well proportioned, or the mixing is not uniform.
All of these may lead to precipitation of epoxy floor paint, resulting in uneven color difference of the whole floor paint, and then lead to color difference. In addition, if construction technology is poor, resulting in uneven overall thickness of the epoxy floor, or when construction, using different batches of floor paint, or the construction interval of each part of the same coating is too long, it may lead to more obvious color difference.
Before undertaking construction, floor enterprises must carry out corresponding construction organization design, from the arrangement of personnel, equipment and materials, to the arrangement of specific construction period, the guarantee measures of quality, safety and duration in construction, and then to the response measures against unexpected situations, etc., and must plan and arrange in place so as to avoid the occurrence of accidents. The unexpected situation has caused problems in the project.
