Two major bottlenecks in the development of new energy-saving building materials

With the promotion of science and technology, with the widespread promotion of energy-saving buildings, the society has put forward new requirements for energy-saving building materials. The market has higher and higher requirements for energy-saving, consumption-reducing, and environmental protection indicators of building materials products. Energy-saving building materials comply with energy conservation and environmental protection. The development has become a hot product. At present, new energy-saving building materials mainly include new wall materials, chemical building materials, new thermal insulation materials, and architectural decoration materials. Although there are market demands, in fact, on the one hand due to the cost and market constraints, on the other hand due to technical barriers, the development of new energy-saving building materials is currently struggling.

The high cost is one of the main factors that hinder the development of energy-saving building materials

The choice of building materials by owners has a direct impact on the development of energy-saving building materials. At present, in the interior decoration, due to the lack of awareness of energy saving and environmental protection, many owners are not willing to pay for the use of new energy-saving and environmentally-friendly building materials. As a result, the formaldehyde content in the room after renovation is excessive, and the indoor air pollution is serious, which not only endangers the health of the owners, but also causes Economic losses also cause huge material waste.

Although new energy-saving building materials have the advantages of high technology content, low resource consumption, long service life, and less environmental pollution, the use cost is not as high as that of general building materials. However, in terms of market prices, it does not have a competitive advantage. The high production cost of energy-saving building materials makes it difficult to lower the selling price of these new products and it is difficult to become the darling of the market. For example, the new insulation material - polyurethane rigid foam, the current share of the use of external wall insulation accounted for less than 10%, only a few large-scale real estate development companies that focus on brand building using polyurethane rigid foam external wall insulation system.

Technical difficulties are another major factor hindering the development of energy-saving building materials

At this stage, the competition of most of China's new building materials companies is concentrated on medium and low-end products. Products with higher technological content are relatively few, and competition in high-end fields is not fierce. The most obvious is the plastic pipe and window and door industry. At present, the production of low-end products in the country has experienced excess capacity and the market growth has slowed down. Domestic plastic pipe and pipe Fittings are mostly general-purpose products. The use of pipe and fittings with high requirements and high added-value has produced less, which has greatly limited its market application. The application of high-end plastic pipe materials is only at the initial stage. The main reason is that the industry lacks investment in science and technology in terms of energy conservation and resources, and the lack of technological innovation has affected the overall level of the industry. The PC transparent board market favored by the market, due to high technical requirements, domestic enterprises can not achieve a breakthrough in technology, most of the market position is occupied by foreign companies.

At present, in the production and sales of high-profit-making wall internal and external thermal insulation panels and roof waterproof materials and other plastic building materials, there are short-sighted behaviors that are quick-acting and quick-acting for production enterprises. They are satisfied with the introduction of technology for simple production and do not pay attention to research and development of proprietary technologies. With new products with high added value, this short-sighted behavior has laid a hidden danger for the development of the industry.

The building energy-saving materials such as cement hollow bricks instead of clay solid bricks and clay hollow bricks have been widely promoted, but there are also many problems with these types of products: First, the strength of the hollow bricks of cement is insufficient. This is in contrast to the partial pursuit of profit maximization and neglect of some hollow brick producers. The quality and safety of building materials are related; Second, there are great differences in the construction methods involving cement hollow bricks, affecting the quality of the project.

In addition to the above-mentioned two major bottlenecks, related incentives and supporting policies are not perfect, the building materials industry itself has low barriers to entry, low concentration, and disorderly market competition, and companies are facing pressure to transfer to high-tech and high-end markets. All of these are important reasons and new directions for the development of new energy-saving building materials that cannot be quickly developed in a short period of time.
