What is the difference between paint and paint?
A: The paint is divided into water-based coatings and oil-based coatings. Many people used to refer to water-based coatings as coatings, and their texture was rough. Oil paint for paint, more fine spots. At present, with the development of science and technology, many oil-based paints gradually change into water-based paints by grafting hydrophilic groups or water-wrapping technology, and the boundaries between the two are becoming less apparent. The meaning of the word itself is changing with the changing times. The name of the paint is the material of the scraping and painting brush, covering a wider range; the paint is the paint of the oil. The ancient one was the anticorrosion paint material that was mixed with tung oil or added mineral pigments. . It can be said that the basic meaning of paint and coating in the industry convergence, there are obvious differences in the minds of outsiders, so often ambiguous doubts.
What is the role of paint?
A: The role played by the coating through the coating can be summarized in three aspects: A. Protection. The surface of the object is coated with a coating to form a protective film, which can prevent or delay the occurrence and development of metal corrosion, wood decay, cement weathering and other damage phenomena, and extend the service life of various materials; B. Decoration effect. Different materials are coated with paints to make them have different colors, different luster, and different textures. They have a colorful and colorful appearance, which can beautify life and work environment. C. Special functions. Some of the modern paint types can provide a variety of special functions, such as: electrical insulation, conductive, shielding electromagnetic waves, anti-static generation, etc.; anti-mildew, sterilization, insecticide, marine bio-adhesion and other biochemical effects; resistance High-temperature, heat preservation, temperature and temperature marking, thermal insulation and other thermal effects; reflected light, luminescence, absorption, and reflection of infrared, solar absorption, shielding rays, marking color and other optical properties; non-slip, self-lubricating, The role of mechanical properties such as anti-fragmentation and splashing: There are also various functions such as anti-noise, shock absorption, sanitation, anti-condensation, and anti-icing. This kind of paint has developed into a kind of functional engineering material in modern times. 1. What is the composition of the paint? A. Film-forming substances: The components required for the completion of the construction process and the composition of the coating film are the basis of the coating and have the function of bonding the other components in the coating to form a coating film. It plays a decisive role in the properties of the coating and the coating film: B. Pigment: The component that gives the coating a color and gives the coating a certain hiding power. It allows the coating to exert its decorative and protective effects, as well as enhance the mechanical properties and durability of the coating. Some pigments can also provide a specific function for the coating, such as anti-corrosion, electrical conductivity, fire prevention, anti-flammability, etc. C. Solvent: The components necessary for liquid coating to complete the construction process except for non-solvent coating. The choice of solvent type is based on the requirements of the coating and the coating film. A paint can use one solvent variety or multiple solvent varieties.
Why choose epoxy floor paint?
A: The molecular formula of epoxy resin is: From the epoxy resin formula can be seen that epoxy resin has the following advantages: A. Due to the presence of hydroxyl and ether bonds, the paint film has excellent adhesion to concrete, wood, metal, plastic, and other substrates; B. Due to the absence of double bonds, when the ring-opening polymerization of epoxy is carried out, the polymerization atoms can only be linked by a covalent bond, and the volume after polymerization does not have a great influence, while for the unsaturated polyester, there are double bonds and the double bonds are opened after polymerization. , And by covalent bonding, the atomic spacing shrinks, resulting in volumetric shrinkage, and internal stress due to volumetric shrinkage can cause adhesion. C. Excellent chemical resistance, no ester bond, so strong alkali resistance and general oils and alkyd rust-proof primer, in the corrosion of the cathode site, will be alkaline, and destroyed; after the epoxy resin film Into a three-dimensional network structure, it is water-resistant, good oil absorption performance, excellent acid and alkali resistance, it is suitable for use in preservative sites. D. Due to the presence of aromatic rings, the mechanical properties of the film are hard; the cross-linking distance of the epoxy resin is long for easy rotation, and the ether bond facilitates the rotation of the molecular bonds and therefore has good toughness, while the phenolic resin cross-linking spacing is close, so it is relatively brittle .
