<b>strengthening the renovation of old residential areas, advocating green building materials, and benefiting the development of polyurethane waterproof coatings</b>

the renovation of old residential areas has intensified, driving the demand for waterproof coatings to grow:

on april 16, at the state council’s regular policy briefing held by the state council information office, huang yan, deputy minister of the ministry of housing and urban-rural development, said: in 2019, 19,000 old residential areas in cities and towns were remodeled, involving 3.52 million households. in 2020, various places plan to renovate 39,000 old urban communities, involving nearly 7 million households, double that of last year.the focus is residential complex built before the end of 2000. at the beginning of this year, the construction industry was affected by the shutn of the epidemic and the delay in resumption of work, so from this set of figures, we can even see the national government’s emphasis on the reconstruction of old areas. if the above plans are fully completed, it will drive further growth in the rigid demand for waterproof coatings this year.

new housing, advocate green building materials:
on april 13, 2020, shortly after wuhan was officially unsealed, the hubei provincial building energy conservation and wall innovation leading group issued the “opinions on building energy conservation and green building development in 2020”, proposing that “urban green buildings account for the proportion reaches more than 40%, and the energy-saving transformation of existing buildings is 2.2 million square meters, and vigorously promotes green building materials”, “government investment projects, key projects, municipal public works, green buildings and ecological urban areas, prefabricated buildings and other projects must continuously improve the application of green building materials rate, setting an example for the promotion and application of green building materials.”
the
earlier in mid-january this year, guizhou provincial department of housing and urban-rural development, provincial development and reform commission, provincial department of finance, and provincial government affairs administration jointly issued a notice of “ten measures to accelerate the development of green buildings”, referring to the housing, urban and rural areas of guizhou province. the department of construction took the lead in organizing the formulation of “ten measures to accelerate the development of green buildings”. the “measures” make it clear that starting from january 1, 2021, all new civil buildings in cities and towns across the province will be designed and constructed in accordance with green building standards. by the end of 2020, the proportion of green building area in newly built civil buildings in cities and towns in the province will reach more than 50%.
green building materials will be the development trend of the construction industry in recent years, which will also benefit the sustainable and steady development of the construction waterproof coating industry.
the
performance of polyurethane waterproof coating companies:
polyurethane waterproof coating is a prepolymer containing isocyanate group formed by addition polymerization of isocyanate, polyether, etc., with catalyst, anhydrous additive, anhydrous filler, solvent, etc., and processed through mixing and other processes one-component polyurethane waterproof coating. this type of coating has many characteristics such as high strength, high elongation, good water resistance, strong adhesion, and convenient construction. its non-toxic and harmless advantages also conform to the development trend of green building materials, and are being developed and promoted by more and more architectural waterproof coating companies.
the
the first echelon of domestic architectural waterproof coating companies includes oriental yuhong, jiangsu kailun and keshun. their sales revenue performance of waterproof coatings in 2019 all performed well. the following briefly lists the business performance of these three companies in waterproof coatings in recent years, as well as their development status and achievements in polyurethane waterproof coatings:
the
oriental yuhong–the main products of oriental yuhong are building waterproof materials, which are widely used in housing construction, high-speed railways, subways and urban rails, expressways and urban roads and bridges, airports and water conservancy facilities, comprehensive pipe corridors and many other fields. in 2019, oriental yuhong’s revenue in the anti-water coating sectorwas 48.75billion yuan , a year-on-year increase of 22.61%. focusing on national strategies such as green building and energy-saving building, oriental yuhong has carried out research on innovative waterproofing products for roofing projects and major green building residences. in the field of green building and residential waterproofing, breakthroughs have been made in the key technologies of high water-resistant polymer waterproof coatings, water-based self-repairing waterproof coatings, one-component quick-drying waterproof coatings and one-component solvent-free polyurethane waterproof coatings, and realized transformation of technological achievements.
the
keshun – kesun company specializes in the research and development, production, sales of new building waterproof materials and provides waterproof engineering construction services. the company’s products cover more than 100 varieties of waterproof membranes and waterproof coatings, and can provide customers with “one-stop” building waterproof solutions. in 2019, the sales revenue of kesunin the anti-water coating sectorwas 923100 million yuan, year-on-year increase57.04%. the one-component low-voc polyurethane waterproof coating independently developed by keshun meets the stringent requirements of db11/3005-2017, and has made a breakthrough to solve the balance between construction technology and voc reduction. graphene-modified polyurethane waterproof coatings have also been put on the market and have been widely praised by users.
the
jiangsu kailun – jiangsu kailun specializes in the research and development, production, sales and waterproof engineering construction services of new building waterproof materials. the company’s main products are new building waterproof materials, including polymer membranes, asphalt-based membranes, polyurethane coatings, polymer cement coatings and polymer self-adhesive tapes. the products are mainly used in high-speed rail, subway, tunnel, civil air defense, underground pipe gallery, airport, nuclear power, water conservancy, grain depot and other public facilities and infrastructure construction projects and industrial and civil buildings. in 2019, jiangsu kailun’s revenue in the waterproof coating segment was 1.4100 million yuan, a year-on-year increase147.18%. the high-tech mpuwhite polyurethane waterproof coating launched by jiangsu kailun in recent years. it is counterfeit, more environmentally friendly, easy to spray, and the construction reliability and construction efficiency are greatly improved. the product has passed the evaluation of scientific and technological achievements of the ministry of housing and urban-rural development and obtained the certificate of scientific and technological promotion, and won the first prize of technological progress in china’s building waterproof industry, and the “voc standard certificate for architectural coatings and adhesive products” issued by beijing green label building materials industry alliance.
