Honghui new material anti-corrosion emulsion: alternative alicylic resin to improve paint performance

Since human society entered the iron and steel age, the harm of corrosion has been there. Because of its slow development process, easy to be ignored, resulting in damage to equipment and facilities, resulting in economic losses. According to statistics, the annual economic losses caused by corrosion in China are equivalent to 4% to 5% of GDP per year

. In fact, the damage of corrosion is not only reflected in economic losses, but also may cause major safety accidents. Therefore, the research and development of high-efficiency, environmentally friendly anti-corrosion coatings has been a new technology research and development of a very urgent task.
At present, anti-corrosion coatings are mainly epoxy resin coatings, alicic acid resin coatings, polyurethane resin coatings, etc. , of which aliclicyptic resin coatings in anti-corrosion coatings occupy an important position, aolic acid resin is the paint synthetic resin in the largest use, one of the most widely used varieties. The traditional solvent-based alkyd resin coating has the characteristics of good adhesion, good gloss and fullness, and easy to use in a single part, but its chemical resistance is poor, poor weather resistance, low hardness, and contains a large number of solvents, causing great harm to the environment and human health;
in view of the above situation, Honghui New Material has developed a co-polyseptic anti-corrosion emulsion of vinyl chloride, which can replace aolic acid resin, model VDAR-20S (see Table 1 for technical indicators). Because the resin contains vinyl chloride monosome, so that the emulsion itself has good resistance to water, acid and alkali and other corrosion resistance, by adding self-crossed monosome, so the preparation of self-crossed anti-corrosion coating has a high hardness, excellent water resistance, salt water resistance and so on, and drying speed, good stability, very good solution to the shortage of alkyd resin.

-a products contain flaky pigments and effect pigments, such as aluminum powder, mica iron oxide, glass scales, pearlescing powder, etc., except for products containing aluminum powder pigments in
-b.
the VDAR-20S primer performance index is better with tables 2 and 3 (see Table 4). It can be seen that the comprehensive performance of VDAR-20S primer can meet the requirements of general anti-corrosion coatings, can meet the anti-corrosion performance standards of aolic acid primer (see GB/T 25251-2010). Therefore, VDAR-20S emulsion can completely replace alicic resin, used in construction steel structures, highway guardrails and other anti-corrosion primers, and more environmentally friendly and safe.
Wuxi Honghui New Materials Technology Co., Ltd. as a collection of vinyl chloride-ethylene acetate co-polyester resin and vinyl chloride co-polypulestion emulsion and its modified water-based products research and development, manufacturing and sales in one of the high-tech enterprises, established in 2001 has gone through 18 years. In the course of 18 years of development, Honghui new materials always adhere to technological innovation, product innovation, to continue innovation, the development of green new chemical materials as its own responsibility, in line with industry trends and national industrial policies and domestic and foreign environmental trends, committed to green chemical new materials technology research and development, can greatly promote the development of downstream water-based coatings, including vinyl chloride co-polypulestion emulsion as the base of water-based industrial coatings.
from Honghui new material over the years the development path is not difficult to see that innovation has always been the soul of the enterprise, can create such an advantage of the product, relying on years of technology accumulation and talent reserves. It is reported that Honghui new material gathered a group of industry senior technical experts, with a number of core technology and high-tech products, more than a dozen national invention patents, for many years has been identified as "high-tech enterprises in Jiangsu Province", "private science and technology enterprises in Jiangsu Province", but also has "provincial enterprise technology center", "provincial engineering and technology research center." The development of industry and technology has led to the breakthrough of Honghui new material technology in related fields, but also to build its own core technology, the achievement of honghui new material advantage products continued output, at the same time, as a listed enterprise, with the capital market, Honghui new material future can be expected.
