Create new advantages to create growth poles “The Chinese Academy of Building Research has traditionally been mainly engaged in the research and development and application of cement-based materials and concrete materials. The start of chemical building materials is relatively late. For example, the current reinforcing materials that are doing well are probably defined as professional development since 2000. To operate in the direction.†Zhao Lanlong, director of the Institute of Building Materials, Chinese Academy of Building Research, frankly stated in an interview with reporters recently. In the eyes of Zhao Xiaolong, the industrialization of chemical building materials is still a “newborn†in the AICPA, but at the same time, he also stated that he will build chemical building materials into new advantages and new economic growth poles in the “12th Five Year Plan†period.

Founded in 1953, the Institute was originally the largest comprehensive scientific research institution directly under the Ministry of Construction. In October 2000, the institute was transformed from a scientific research institution into a science and technology enterprise directly under the State-owned Assets Supervision and Administration Commission of the State Council. It is currently the largest integrated research and development institution in the construction industry with the most complete disciplines in China. Its business scope covers 79 areas including building structure, seismic resistance, construction materials, foundations, residential systems and products, intelligent buildings, construction engineering and material testing.
Chemical building materials are the fourth generation of new building materials following steel, wood and cement. According to Zhao Yulong, the research and development of the chemical building materials of the Academia Sinica is mainly focused on the Institute for Building Materials. In order to speed up the transformation of related scientific research results, the Institute established the Jianyan Building Materials Co., Ltd. in 2005, mainly engaged in reinforcing materials, concrete, waterproof materials, admixtures, wall thermal insulation materials and decorative materials, etc. Business activities.
“At present, the chemical building materials involved in the building materials of the Institute are mainly concentrated in three areas: concrete admixtures, structural structural reinforcements, and waterproof materials.†Zhao Xiaolong said, “Concrete admixtures are the starting materials for chemical building materials.†According to him In the introduction, the Building Materials Institute independently developed additive products such as polycarboxylate water reducers, naphthalene sulfonate water reducers, and melamine water reducers. The current products are mainly CABR series concrete admixture products, including CABR- SF low-shrinkage type hydrazine superplasticizer, CABR-SJ early strength water reducer, CABR-SL concrete anti-cracking agent, CABR-PCA polycarboxylate high performance water reducer, CABR-SN naphthalene series superplasticizer, etc. product. Its additive products have been used in the "Bird's Nest" concrete project of the Beijing Olympics, the expansion of the Beijing Capital International Airport, and the 100,000 tons/year polypropylene plant concrete project of Sinopec Yan'an. In terms of concrete admixtures, the Building Materials Institute has also compiled a number of national and industrial standards.
With the increase in the amount of building reinforcement and renovation projects, various new types of reinforcement materials continue to emerge. According to Zhao Yulong, the output value of Kunlun brand structural reinforcement rubber and grouting material produced and sold by China Jianyan Building Materials Co., Ltd. has always been the largest in the chemical building materials field of building materials. The annual output value is about 20 million yuan, and the product performance is in the domestic advanced and even Leading level. Since 2002, the occupancy rate of Kunlun brand reinforcement materials in the domestic market has been increasing year by year, and application engineering has spread throughout the country. It is understood that Kunlun reinforcement material product system mainly includes: fiber composite materials, building structural reinforcement glue, MS series of migratory organic composite steel rust inhibitor, high strength steel strands - polymer mortar, dry mortar and so on. One of the steel rust inhibitors has been used in Xinjiang Dushanzi Petrochemical 1 million tons/year ethylene project, Inner Mongolia Duolun Datang coal chemical project, Qingdao petrochemical refining project.
In terms of waterproof materials, the Building Materials Institute successively carried out the development of JS waterproof coatings, acrylic waterproof materials, environment-friendly two-component color polyurethane waterproof coatings, and epoxy resin floor coatings. At present, JS waterproof coatings and environmental protection have been formed. Polyurethane waterproof coating, inorganic fast plugging material, environmentally friendly chemical grouting material based product system. According to Zhao Xiaolong, the self-developed penetrating crystalline waterproof material has been successfully applied to the anti-seepage project of the Shenhua Coal-to-oil Plant in Ordos. In addition, in the field of waterproof and plugging materials, the institute also undertakes funded projects funded by the Scientific Research Institute of the Ministry of Science and Technology. Its main tasks are to develop self-repairing waterproof coatings for cracks, high-performance polyurethane waterproof coatings, and high-efficiency waterproof coatings for roads and bridges.
In the field of wall insulation materials, building materials has always been the country's key issues. Zhao Yulong introduced that the research topic of the polyurethane rigid foam external wall insulation system undertaken by building materials has been completed, and related achievements have played an important role in promoting the use of polyurethane rigid foam as a building insulation system. For example, in 2010, Bayer MaterialScience and the R&D Institute jointly developed a spray polyurethane foam wall insulation system and successfully developed a new polyurethane material for the curtain wall fire insulation system.
Zhao Yulong introduced that during the "12th Five-Year Plan" period, the research on the highly efficient flame-retardant and high-efficiency insulating organic foam external wall thermal insulation system jointly undertaken by the China Academy of Building Materials and the China Building Materials Group in the field of wall thermal insulation materials has been officially launched. In the field of waterproof materials, it is planned to develop a series of waterproof products with longer-lasting waterproof effect, more prominent environmental protection performance and higher cost performance, and at the same time develop a batch of construction repair and sealing materials. In addition, structural reinforcement materials must also be developed in the direction of simple construction, cost-effectiveness, and functional compounding, and develop high-performance, environmentally-friendly products.
