A new type of waterproof sealing material is coming soon

It is understood that according to the current situation and existing problems of my country's building waterproof materials, considering the future needs and actual possibilities, and referring to foreign experience, the technical route of my country's building waterproof materials is also advancing in the process of learning.

In the industry, it has become the mainstream to restrict paper base felt and vigorously develop modified asphalt felt. In addition, actively promote polymer waterproof membranes, properly develop waterproof coatings, strive to develop sealing materials, and pay attention to the development of underground water stop , plugging materials and rigid polyurethane foam waterproof and thermal insulation materials, gradually reduce the low-grade materials and correspondingly increase the proportion of various medium and high-grade materials, comprehensively improve the overall level of waterproof materials in my country, and correspondingly solve the relevant construction machinery, supporting materials and construction The technology can completely cure serious building leakage and ensure the steady improvement of the service life of waterproofing projects.

In terms of modified linoleum, focus on the development of SBS modified linoleum, and actively create conditions to promote the increase in the production of APP modified linoleum, and gradually reduce or cancel reclaimed rubber modified asphalt linoleum. In terms of carcass for modified linoleum, polyester felt, glass fiber felt and polyester fiberglass composite tires are advocated, and cotton fiber-based composite carcasses are restricted or even eliminated.

Focus on promoting EPDM membranes for polymer waterproof sheets, actively develop a new generation of PVC waterproof membranes, limit CPE-based waterproof membranes, and eliminate reclaimed rubber waterproof membranes.

Waterproof coatings should focus on the development of polyurethane and acrylic water-emulsion waterproof coatings and rubber-modified asphalt waterproof coatings. Polyurethane waterproof coatings are transitioning from coal tar type to petroleum asphalt polyurethane and pure polyurethane. Actively develop and promote high-solid-content and high-quality rubber-modified asphalt coatings in terms of rubber-modified asphalt coatings, greatly reducing or even eliminating the use of PVC and plastic ointment. Actively develop acrylic and other exterior wall waterproof coatings to solve the problem of wall leakage.

For sealing materials, it is advisable to focus on the development of sealing pastes for construction and automobiles. The focus of development should be on the two types of elastomeric sealing pastes, silicone and polyurethane, and the appropriate development of medium and high-grade sealing pastes such as polysulfide and acrylic.
