Building development, and the current status of building insulation is that the existing insulation cannot keep up with the situation, the hidden danger of fire is lingering, and the phenomenon of falling off is becoming more and more serious. Functional coatings such as thermal insulation, anti-mildew and antibacterial coatings represented by MiG have shown good market application prospects and can meet the higher requirements of buildings for energy conservation and safety. Since 2020, China National Inspection and Quarantine Group, Tianyu Technology and MiG have jointly created an intelligent evaluation system for MiG's thermal insulation coatings, which through continuous dynamic monitoring of solar radiation, outdoor temperature, heat flow, wind and other parameters ; Through the control of indoor temperature and humidity and continuous monitoring of power consumption, the application effect and energy-saving evaluation of thermal insulation coatings in different climates and different periods of time can be realized. At present, the system has undergone three phases of testing and data collection. Based on this, this technical exchange seminar is held.

Jiang Quan, chief engineer and professor-level senior engineer of China National Building Material Inspection and Certification Group

 

Professor Jiang Quan first thanked MiG and the experts and leaders who promoted the development of thin-body thermal insulation coatings. The National Inspection and Quarantine Group has been researching and promoting radiation-type building energy-saving materials over the years, and has done a lot of testing and data collection and drafting. A series of standards for thin-body thermal radiation coatings have been compiled, among which T/CIE082-2020 "Test Method for Thermal Insulation Temperature Difference of Thermal Insulation Coatings" and T/CSTM00292-2021 "Energy-saving Evaluation Method for Building Thermal Insulation Coatings" are now available. It has been released, and the standard can provide technical support for the evaluation of the energy-saving performance of thermal insulation coatings. A large number of research results and analysis of test data show that radiant coatings are indeed safe, reliable, energy-saving and environmentally friendly. According to survey data, carbon emissions from buildings and building materials account for more than 50% of total carbon emissions. , And high-performance radiant coatings will provide new solutions for green buildings, low-carbon buildings and even zero-carbon buildings. Finally, Professor Quan Jiang also shared with the participants on the microclimate that MiG Coatings can greatly improve the indoor environment.

Professor Lu Pihe, an expert on the Science and Technology Promotion Platform of the Ministry of Housing and Urban-Rural Development and the National Center for Testing and Evaluation of New Materials

 

Professor Lu Pihe has been committed to the research and promotion of thin-body radiation shielding materials since more than ten years ago, and has done a lot of work for the mechanism, testing and standard promotion of this material. Professor Lu believes that the climate difference between the north and the south is huge in our country. The heat conduction heat insulation and energy-saving methods are used to wear quilted jackets on all buildings, which is not fully in line with the actual situation of our country. The cooling time is generally more than four months. For example, in Hangzhou, Zhejiang, the cooling energy consumption in summer is nearly 90 times that of heating in winter. The conductive heat insulation method not only does not save energy, but consumes energy, which is more advanced than conductive heat insulation. It is radiant heat insulation. This method is mainly based on the temperature difference of blocking heat radiation as the judgement. The greater the temperature difference, the greater the thermal resistance. Professor Lu said that in recent years, the detection and design of domestic building envelope structure are mainly heat conduction, and there is little research on heat radiation technology. For this, Professor Lu has asked experts from the Academy of Construction Sciences, the Institute of Building Materials, the National Inspection and Quarantine Group, and the MiG The company is dedicated to the hard work promoted by the research and development of heat radiation materials and expresses its sincere respect. And express my heartfelt gratitude to the leaders of the Ministry of Housing and Urban-Rural Development and the provincial and municipal housing construction departments for their care and support.

Pei Chao, engineer of the National Building Materials Industry Building Materials and Structural Safety Quality Supervision and Inspection Center, made a keynote report

 

The topic of this keynote report is "Test Data Analysis of Energy-saving Evaluation Methods for Building Thermal Insulation Coatings". In the report, Mr. Pei explained the relevant background and development significance. The types of coatings have evolved from decorative protective coatings to functional coatings in the past. Some coatings It can achieve a certain energy saving effect by blocking, reflecting, and radiating heat energy. There is no mature detection method for radiant energy-saving coatings and radiation composite energy-saving coatings to evaluate its thermal insulation performance. In order to provide effective and solid testing data for the CECS standard "Building Thermal Insulation Coatings"; promote the market application of thermal insulation coatings, solve the many disadvantages of traditional thermal insulation materials, and meet the energy-saving and safety effects of domestic existing buildings and new buildings. Higher requirements for performance. Minister Pei introduced the thermal performance testing methods of thermal insulation coatings, and analyzed the "Determination and Calibration of Thermal Insulation Steady-State Heat Transfer Properties and Protective Hot Box Method", "Testing Methods for Thermal Insulation Temperature Difference of Thermal Insulation Coatings", and "Building Thermal Insulation The actual application test of the three methods of Coating Energy Conservation Evaluation Method, and the introduction of the "Energy Conservation Evaluation Method for Building Thermal Insulation Coatings" based on the experimental cabin comparison method. Through the three-stage monitoring data analysis, the test proves that the thickness The energy-saving effect of the 0.4mm MiG thermal insulation coating and the 35mm molded polystyrene board (the thermal conductivity of the molded polystyrene board is 0.042W/mk) is the same.
