Description

Construction method of waterproof coiled material

Technical Field

Background

In recent years, environmental problems are increasingly highlighted, and various pollutants are discharged and suspended in the atmosphere in the form of fine particles through a series of physical and chemical processes, so that when the surface of a material is exposed outdoors, harmful substances in the air are easily adsorbed due to electrostatic action, the attractiveness of the material is affected, and the health of people is threatened. For example, Thermoplastic Polyolefin (TPO) waterproofing membrane is widely used for constructing a roof waterproofing system as one of the most important building waterproofing materials at present, and when the TPO waterproofing membrane is used outdoors, a large amount of dust and other pollutants are often adsorbed due to the fact that the traditional TPO waterproofing membrane has no self-cleaning function.

The current solution to the above problem is to apply a self-cleaning coating on the surface of the material to form a self-cleaning surface. Generally, a self-cleaning surface refers to a surface on which contaminants or dust on the surface can automatically fall off or be degraded under the action of gravity or external force such as rain or wind. After the self-cleaning material is coated to form a self-cleaning surface, the surface of the material can be kept clean under natural conditions without manual cleaning, so that the cleaning cost and the labor intensity of workers are greatly reduced, and the potential safety hazard caused by manual cleaning is reduced. At present, more self-cleaning materials are researched, have building, pipeline transportation, traffic and the like related to industrial production, and show wide application prospects.

However, most of self-cleaning materials in the prior art, such as self-cleaning TPO waterproof rolls, have self-cleaning layers coated on the surfaces before leaving factories, so that the phenomena of partial abrasion and damage of the self-cleaning layers on the surfaces exist in the transportation and construction processes of the materials, the self-cleaning effect of the surfaces is reduced, and even the self-cleaning effect is lost.
