Embodiment Construction

[0005] 1. Cement-based permeable crystalline waterproof bonding material

[0006] The cement-based osmotic crystalline waterproof bonding material of the present invention is formed by using ordinary Portland cement, quartz sand and other inorganic materials as base materials, adding active compound osmotic crystalline masterbatch, polymers and other various auxiliary materials. A powder material, which is a non-toxic, odorless and pollution-free environmentally friendly rigid waterproof material.

[0007] The waterproof mechanism of the cement-based permeable crystalline waterproof bonding material is: after the active compound contained in the waterproof bonding material reacts with water, it uses water as the carrier to penetrate into the capillary pores of the internal structure of the concrete, and penetrates into the internal pores of the concrete. The active compound reacts with the free calcium oxide in the concrete to form water-insoluble dendritic fibrous crystals (c...

Abstract

The invention discloses a waterproof binding material. According to the invention, inorganic materials such as silicate cement, quartz sand and the like are adopted as base materials. Active compound permeable crystalline masterbatch, polymer and various other auxiliary materials are blended into the base material, such that a powdery waterproof material is obtained. The composite waterproof system provided by the invention is composed of the waterproof binding material and a macromolecular polyethylene polypropylene waterproof coiled material. Two surfaces of the macromolecular polyethylene polypropylene waterproof coiled material are composed of high-density polypropylene filament non-woven fabrics. A main water proof layer is prepared from the process of adding an anti-aging agent, a stabilizing agent, an auxiliary agent, and the like into linear low-density polyethylene. According to the invention, a composite waterproof system with an optimal waterproof effect is selected from various possible binding materials and waterproof coiled materials. As a result of testing, the composite waterproof system provided by the invention has excellent permeation resistance, excellent water-pressure resistance, excellent corrosion resistance, excellent aging resistance, excellent self-repairing capacity and excellent environment protecting characteristic.

Description

technical field [0001] The invention relates to a waterproof bonding material, especially a cement-based permeable crystalline waterproof bonding material. The invention also relates to a composite waterproof system composed of the waterproof adhesive material and waterproof coiled material. Background technique [0002] Building waterproofing is an important technology in construction engineering. The waterproof performance is directly related to the quality and service life of buildings. Strongest, most complained about issue. Practice has proved that the use of a single waterproof method or material cannot solve the problem of building leakage. It is necessary to use a composite waterproof system to give full play to the complementary advantages of various waterproof methods or materials in order to achieve the ideal waterproof effect. Although it has been recognized that the use of waterproof adhesive materials and waterproof membranes will greatly improve the waterpro...
