Problems solved by technology

[0003] In the prior art, on the one hand, the traditional asphalt-based waterproof materials have low peel strength and insufficient waterproof performance. With the prolongation of use time, their waterproof performance weakens; on the other hand, the use of asphalt-based materials has brought environmental pollution problems , affecting the health of construction workers, so it is urgent to develop new non-bitumen-based waterproof materials with good water resistance

Embodiment 1

[0016] A waterproof material, comprising a fetal membrane, an isolation membrane and a polymer colloid, the polymer colloid is uniformly placed between the fetal membrane and the isolation membrane polymer colloid, and is formed by mixing the following components by weight: 48 parts of hot melt adhesive; 5 parts of naphthenic oil; 20 parts of white cement; 60 parts of quartz sand; 1 part of green pigment; 5 parts of nano-silica, 3 parts of nano-alumina.

[0017] The preparation method of polymer colloid is the following steps:

[0018] 1) Weigh the hot melt adhesive and naphthenic oil by weight and put them into the oxidation kettle, heat to 150°C, melt and stir evenly;

[0019] 2) Add white cement, quartz sand and green pigment to the mixture prepared in step 1), heat at 180° C., stir evenly, and prepare polymer colloid.

Embodiment 2

[0022] The preparation method of polymer colloid is the following steps:

[0023] 1) Weigh the hot melt adhesive and naphthenic oil by weight and put them into the oxidation kettle, heat to 110°C, melt and stir evenly;

[0024] 2) Add white cement, quartz sand and green pigment to the mixture prepared in step 1), heat at 150° C., stir evenly, and prepare polymer colloid.

Embodiment 3

[0026] A waterproof material, including a fetal membrane, an isolation membrane and a polymer colloid, the polymer colloid is uniformly placed between the fetal membrane and the isolation membrane polymer colloid, and is formed by mixing the following components by weight: 30 parts of hot melt adhesive; 2 parts of naphthenic oil; 15 parts of white cement; 50 parts of quartz sand; 0.5 parts of green pigment; 3 parts of nano-silica, 2 parts of nano-alumina.

[0027] The preparation method of polymer colloid is the following steps:

[0028] 1) Weigh the hot melt adhesive and naphthenic oil by weight and put them into the oxidation kettle, heat to 150°C, melt and stir evenly;

[0029] 2) Add white cement, quartz sand and green pigment to the mixture prepared in step 1), heat at 170° C., stir evenly, and prepare polymer colloid.

Abstract

The invention discloses a waterproof material comprising a tire film, a separator film and a polymer colloid. The polymer colloid is uniformly applied between the tire film and the separator film, andis obtained by mixing the following components by weight: 20 to 48 parts of a hot melt adhesive; 1.7 to 5 parts of naphthenic oil; 10 to 20 parts of white cement; 30 to 60 parts of quartz sand; 0.3 to 1 part of a green pigment; 1 to 5 parts of nano silica and 1 to 3 parts of nano-alumina. The waterproof material has excellent weather resistance, peeling strength and waterproof performance, can build a skin-type waterproof barrier for building materials, adopts an environmentally-friendly non-asphalt-based raw material, and has uncomplicated components, simple preparation process, low production cost, economical and environmental protection characteristic, and broad prospects for large-scale industrial application.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a waterproof material. Background technique [0002] At present, my country's waterproof materials are still dominated by asphalt-based waterproof materials, accounting for 65% of all waterproof materials, polymer waterproof membranes account for about 15%, and other waterproof materials account for about 20%. Among them, the polymer waterproof membrane is a typical new building waterproof material. Because of its excellent performance, in line with the purpose of building material innovation, and the rise of light steel structure buildings, it has developed very rapidly in recent years. [0003] In the prior art, on the one hand, the traditional asphalt-based waterproof materials have low peel strength and insufficient waterproof performance. With the prolongation of use time, their waterproof performance weakens; on the other hand, the use of asphalt-based materials has brough...
