From the experimental results, it is known that the abrasion resistance of the coating film added with colloidal silica is greatly improved compared with the blank sample. When the content is 28%, the turbidity is reduced by 83% compared with the blank sample (after 100 cycles) ) And 88% (after 500 laps), compared with 50% content, the wear resistance has reached the maximum value, which is the optimal addition amount, so there is no need to increase the addition amount of colloidal silica.
The current preparation and surface modification methods of inorganic nano-silica used as wear-resistant agents in coatings can obtain transparent coating films, low-viscosity coating systems and greatly improved wear resistance.
The development of emerging nanotechnology is in the ascendant, and the application of inorganic nanoparticles as anti-wear agents in coatings is also in its infancy, research and development stages. The purpose msds sasol wax is to find cheap and high-quality access and suitable and feasible methods for industrial production and application. It has been achieved internationally. Some achievements and applications, Chinese paint workers have also begun to explore. Looking to the future, its prospects are considerable.
Cured coatings, especially those outdoors, are often exposed to sunlight (mainly long-wave ultraviolet light and short-wave visible light), heat, humidity, oxygen, ozone, oil, acid mist, aromatic compounds in exhaust gas and other pollutants , The aging behaviors such as oxidation, degradation, rearrangement, acidolysis or excessive crosslinking of the polymer chains inside the coating may occur, which manifests as decreased gloss, fading, yellowing, chalking, and brittleness of the coating, which will eventually make the coating It peels off and loses its protective and decorative functions. The yellowing behavior in the early stage of aging will also affect the visual aesthetics of the coating, which is very critical in varnish, white and lightly pigmented coatings. Among all the aging forms of coatings, chemical bonds and polymer chain scission reactions are the most common structural changes. Therefore, when studying the aging behavior of coatings, polymer degradation reactions are often taken as an important indicator. The aging process is often manifested as a complex oxidation reaction of the polymer. The result of oxidation generally leads to the formation of carbonyl groups on the polymer structure, and even polymer chain scission, as well as the production of polar groups such as peroxide groups and hydroxyl groups. Therefore, the slow oxidation reaction performance of the coating polymer is often used as a measure of aging.
