Product development direction
In recent years, my country has made great progress in the research and development of waterproof coatings. With the development of society, people are paying more and more attention to the environment and physical health, so waterproof coatings should also develop in the direction of green environmental protection. The limit of harmful substances in the product should comply with the "Limit of Harmful Substances in Building Waterproof Coatings" JC 1066-2008 and "Technical Requirements for Environmental Labeling Products Waterproof Coatings" HJ 457-2009 Technical requirements.
At the same time, it is necessary to develop water-soluble waterproof coatings and eliminate solvent-based waterproof coatings. Develop from low-grade to high elasticity, high durability and functionality. Products should develop spray-on quick-setting rubber asphalt waterproof coatings, water-based non-curing rubber asphalt waterproof coatings, water-emulsion modified asphalt waterproof coatings, water-based polymer waterproof coatings, etc.
Strengthen technological innovation and develop high-tech waterproof coating products. Vigorously research, develop and promote high-performance (high-strength, high-elongation waterproof coatings), high-weather resistance, environmentally friendly and multifunctional waterproof coatings, such as exposed aliphatic polyurethane waterproof coatings, slow-curing single-component and double-component polyurea waterproof coatings, and high-performance polyurethane waterproof coatings, to promote technological progress in the waterproof industry and meet market needs.
New mechanized spraying construction process
With the advancement of science and technology, waterproof coatings have been applied to various large and medium-sized waterproof projects. The mechanized spraying technology of waterproof coatings has attracted people's attention. While foreign waterproof spraying equipment has entered my country, many domestic companies have also successively developed mechanized spraying equipment suitable for polymer waterproof coatings, spray polyurea waterproof coatings, polyurethane waterproof coatings, spray quick-setting rubber asphalt waterproof coatings, non-curing rubber asphalt waterproof coatings, etc. Vigorously developing spraying equipment and spraying construction technology that are suitable for various types of waterproof coatings and various construction environments can not only improve construction efficiency and construction quality, but also reduce construction costs, which will surely promote the rapid development of waterproof coatings.
Promote new processes for composite use with other waterproof materials
The coating can be well bonded to the concrete and mortar base, which can effectively prevent the occurrence of water leakage. Therefore, the composite use of coatings and other waterproof materials can not only improve the waterproof grade, but more importantly, it can greatly improve the waterproof function and waterproof effect by composite with waterproof membrane or rigid waterproof material. The composite use of non-curing rubber asphalt waterproof coatings and various types of waterproof membranes can effectively reduce the construction quality problems caused by human factors. This waterproofing method has been widely recognized by the waterproofing industry and is a waterproofing method worthy of promotion and application.
Continuously improve construction methods and improve the quality of waterproof construction
While vigorously advocating the use of new building waterproof materials, we should also speed up the research and formulation of various types of waterproof coatings construction technology and construction technical regulations. When formulating national standards and regulations, we should pay attention to the construction technology and construction methods of waterproof materials. Good waterproof materials also require good construction technology and construction methods.
Attach importance to technical training of construction personnel
Attach importance to the training of construction skills of waterproof construction personnel, improve the quality of construction personnel, and improve the quality of waterproof construction.
Waterproof coatings account for 1/4 of the share of waterproof materials, so waterproof coatings are waterproof products worthy of attention in the waterproofing industry, and it is very necessary to develop new waterproof coatings.
Manufacturers should strengthen self-discipline and produce waterproof coatings that meet product quality. Quality supervision departments should not only supervise the quality of waterproof products of manufacturers, but more importantly, conduct quality inspections on waterproof materials sold on the market and used on construction sites, and form a mechanism.
On the basis of existing products, it is necessary to further standardize the product standards of waterproof coatings. In formulating specifications, regulations, and construction standard drawings, the application environment and technical conditions of various types of waterproof coatings should be clarified, and corresponding construction processes and methods should be formulated.
Although the waterproof coating is restricted by the ambient temperature during molding, the mechanical properties of the film layer are affected by the molding ambient temperature and humidity, and the flatness of the base surface, and the film layer has uneven thickness, the flaws do not cover the merits. Waterproof coatings are still irreplaceable products for other waterproof materials such as waterproof membranes.
