Give back to the industry, 2020 Paint Industry, the 10th issue of the electronic version, priority publishing - free reading.

In recent years, while the production of coatings has increased, the industry and product structure have also changed greatly.
the focus and direction of the adjustment of the industrial structure of china is to encourage the production of environment-friendly and resource-saving coatings, environmental protection and functionalization are still the trend of the development of coatings today, and are the key forces driving the market demand in the future.
with the rapid development of bridge tunnels, automobiles, high-rise buildings, oil reserves and other related fields, water-based coatings have been widely used in the field of industrial corrosion protection.
, Wu Haipeng and other plant oleic acid as a bio-based resin, through the esterification reaction to the epoxy resin modified, the preparation of a single-group self-intersecting epoxy acrylic emulsion.
Wenlong and so on through the adjustment of emulsified asphalt process and coating formula, has produced a better adhesion performance and a certain anti-corrosion performance of the water-based oil sands asphalt coating.
Xinliang and other selected solution stripping legal preparation of graphene (PG) to water-based epoxy zinc-rich coatings to change, replacing some zinc-rich coatings in zinc-rich coatings, prepared a low-zinc content of graphene water-based epoxy zinc-containing coatings.
Wang Yongcai and other water-based acrylic hydroxyl emulsions as film-forming substances, water-based isocyanate for curing agent prepared excellent performance suitable for liquefied natural gas (LNG) storage tanks of water-based polyurethane finish, can replace solvent-based finish.
the performance of the coating should consider not only the influence of atmospheric environment, but also the influence of external cross-strain stress, construction conditions, etc.
Taking the steel box-concrete combination bridge anti-corrosion coating as an example, Zhao Fukang and others used ANSYS software to establish a local nonlinear analysis model of the maximum stress area of the steel box-concrete combination bridge, and analyzed the fatigue stress and the crack development mode of the coating under the fatigue load of the coating and the steel structure substrate.
Taking the bare wire of the high-voltage overhead line of the power grid with single-component room temperature silicone sulfide rubber (RTV-1) as an example, Zhao Farqiang and others added 4 kinds of amino silane coupled agents to the RTV-1 to change, which can effectively improve the adhesion performance of the coating interface and the drying time.
To polar ships with low temperature wear-resistant coatings as an example, Chen Kaifeng and other polyurethane and nanoparticle toughened epoxy resin, the use of wear-resistant fillers to reduce coating wear and surface friction coefficient, prepared epoxy coating with excellent impact resistance and wear resistance.
addition, this issue also has a number of articles on powder coatings, VOCs emission performance system research, mandatory standards of harmful substances limit interpretation and imported paint filing countermeasures, etc. for readers to learn from.
the latest issue free of charge in the coatings industry's online APP "Journal Magazine" module.
