Zhejiang Province: Suggestions for Waterproof Industry Planning during the Twelfth Five-year Plan

Since the reform and opening up, China's waterproof industry has undergone tremendous changes. The new type of building waterproof material has been continuously developed. The variety of waterproof materials has basically adapted to the requirements of buildings for waterproof materials, and has contributed to the healthy development of the national economy.

Waterproofing companies in Zhejiang Province are mainly based on joint-stock companies and private companies. They have few technical personnel, weak R&D capabilities, few independent innovation technologies, and a single business model. The scale is generally small. The production volume of modified bitumen membranes for enterprises is generally 5 million square meters per year, and the majority of asphalt-composite tires are flexible waterproofing membranes, and the development of glass fiber tire asphalt shingles is rapid, and the production of self-adhesive waterproofing membranes also tends to increase. However, the development of polymer waterproofing membranes has been lagging behind, and waterproof construction companies lack the training of key projects.

In recent years, the product innovation of the waterproofing industry in Zhejiang Province has developed, such as the integration of waterproof and thermal insulation technology, the spraying of waterborne neoprene emulsified asphalt paint, waterproof breathable film, etc., which has added vitality to the Zhejiang waterproofing industry, but with other domestic There is still a long way to go for the rapid development of regional waterproofing companies.

During the “Twelfth Five-Year Plan” period, in order to implement the requirements of the scientific concept of development and changes in the economic growth mode, in light of the actualities and trends in the development of the domestic and foreign waterproof industries, combined with the actual situation of the Zhejiang Waterproof Industry, the author proposes the following suggestions:

Vigorously develop new types of building waterproof materials and continue to develop elastomer-modified bitumen membranes and plastic-modified bitumen membranes (The proposed new asphalt-type waterproof membrane production line must have a production capacity of 10 million square meters per year or more), eliminating asphalt. Composite tire flexible waterproof membrane; Encourage the development of EPDM waterproof membrane, and eliminate polyethylene polypropylene composite waterproof membrane.

Strengthening the training of talents in the waterproofing industry is fundamental to the sustainable development of the industry. Strengthen the research and development of waterproof material production technology, construction technology, construction equipment, and encourage technological innovation. Actively develop waterproof coating technologies and products, such as spray polyurea, spray water-based waterproof coatings, and polyurethane waterproof coatings.

Strengthening the formulation, specification and strict implementation of new waterproof material standards for self-adhesive waterproofing membranes is a product that has developed rapidly in recent years. However, there are several regionally similar standards in the country. Some quality indicators are lower than national standards and are easily misleading. Consumers ultimately affect the development of this type of waterproof material.

Strengthen the study of special waterproof technology Develop planting roof waterproofing technology, solar roof waterproofing technology, underground engineering waterproofing technology, tunnel engineering waterproofing technology, waterproof and thermal insulation integration technology.
