Do you know these kinds of building waterproof materials?

2021-09-09    1103

In recent years, the application of building waterproofing has been extended from a single building waterproofing to high-speed railways, tunnels and bridges, highways, subway tunnels, landfills, sewage treatment and other engineering construction fields. Waterproof materials are also changing with each passing day. The following types of buildings Waterproof materials are worthy of development.

(1) Spraying quick-setting rubber asphalt waterproof coating: product introduction——Spraying quick-setting polymer rubber asphalt waterproof coating is a water-emulsion spray coating composed of rubber modified asphalt emulsion and coagulant. It is sprayed with special spraying equipment. Fast film formation.

1. Product features

1) Ultra-high elasticity, the coating uses a variety of high-content rubber to modify the asphalt, emulsified and cross-linked into nanometer fineness, the coating film has a breaking elongation of more than 1000% and an elastic recovery rate of more than 85%.

2) Using spraying technology, high efficiency, seamless connection, no water channeling. It has unique features for special-shaped structures or objects with complex shapes, and the construction is very simple and convenient.

3) Strong adaptability to the base level, and can be used on base materials such as reinforced concrete, profiled steel plates, plastics and various masonry materials.

4) The spraying surface treatment is simple, and there is no need to make the leveling layer if there is no special requirement, and directly apply on the base surface with appropriate moisture.

5) The coating has superior weather resistance, acid and alkali resistance, and aging resistance.

6) Long service life, can be used at no lower than 0℃, with excellent anti-peeling and puncture resistance.

7) During the construction process, it can be operated continuously, does not contain volatile organic compounds, is non-toxic, odorless, has no exhaust gas emissions, does not pollute the environment, and can be applied in a confined space.

8) Fast film formation, curing and forming within a few seconds after spraying.


2. Scope of application

1) External waterproofing of underground structures: subways, building basements, common trenches (cables, optical cable trenches), etc.

2) Roof waterproof: concrete flat roof, color steel sandwich insulation board, slate tile, etc.

3) Artificial lakes, pools, waste treatment plants, sewage treatment plants, sedimentation tanks, etc.

4) The bridge deck is waterproof.

5) Anti-corrosion and anti-fouling of vehicle chassis and ships.

(2) Non-curing rubber asphalt waterproof material: Product introduction —— Non-curing rubber asphalt waterproof coating is a plastic paste made of rubber powder, modified asphalt and special additives. It has a long-term non-curing waterproof material.

1. Product features

1) No curing, solid content greater than 98%, almost no volatile matter, and always maintain the original state of colloid after construction;

2) Strong adhesion, can be constructed on wet base surface, and can be bonded with any foreign matter, the materials will not separate during construction, and can form a stable and seamless waterproof layer;

3) Good creep performance, good flexibility, high elongation, suitable for base layer deformation;

4) Strong self-healing ability, even if the waterproof layer is damaged during construction, it can be repaired by itself to maintain a complete waterproof layer;

5) The construction is simple, and it can be applied by scraping or spraying. It can be constructed at room temperature or below zero;

6) It can prevent water from flowing in the waterproof layer, and it is easy to maintain and manage;

7) It can be used simultaneously with other waterproof materials to form a composite waterproof layer to improve the waterproof effect;

8) Durability, corrosion resistance, high and low temperature resistance, excellent extension performance, non-toxic, odorless, non-polluting, and non-flammable.

2. Scope of application

1) Widely used in non-external waterproofing projects in various fields, industrial and civil buildings and planting roofing projects.

2) Underground structures, subway stations, tunnels, bridge decks and other projects.

3) Deformation joint plugging project.
