Problems solved by technology

Because the thickness of the waterproof membrane is very thin, generally between 1.0 and 1.5cm, it not only has low weather resistance and short service life, but also is prone to leakage. Leakage, affect the use
[0003] At the same time, because the waterproof membrane has been used outdoors for a long time, the use environment is relatively harsh, and it has to withstand the erosion of ultraviolet rays and various atmospheric pollutants for a long time, and it is easy to degrade; Sticky, so that the product is easy to stick to dust, crack, and the service life of the product is short, so it is necessary to coat a layer of weather-resistant protective layer on the surface of the waterproof membrane, on the one hand, reduce the erosion of ultraviolet rays on the surface of the waterproof membrane, and improve the service life of the product , on the other hand, it has antifouling and self-cleaning effect

Abstract

A preparation technology of a waterproof roll material with long service life includes the following steps: 1) preparation of a blank membrane, 2) preparation of an upper layer adhesive membrane, 3) preparation of a lower layer adhesive membrane, 4) preheating and heating of mesh, 5) preheating and heating of the upper and the lower layer adhesive membranes, 6) adhesion of the three layers of membranes, and 7) surface treatment. The reasonable preparation technology is adopted, and the technology is more complete, scientific and reasonable; the upper and the lower surfaces of a product are respectively coated with a surface treatment layer which not only plays roles in pollution prevention and product protection, but also achieves pollution-prevention self-cleaning effects in virtue of rain water; meanwhile, the thickness of the product prepared by the technology achieves 2.5-3.0cm, the increase in the thickness of the product improves the product durability and uvioresistant capability, thereby enhancing the waterproof effect of the product and prolonging the service life of the product.

Description

technical field [0001] The invention relates to a preparation process of a waterproof coiled material, in particular to a preparation process of a waterproof coiled material with long service life, antifouling and self-cleaning. Background technique [0002] Existing waterproof membranes are all made of hydrophobic materials, which generally have the advantages of economy, energy saving, self-cleaning, etc., so they are more and more widely used in the field of modern construction. Because the thickness of the waterproof membrane is very thin, generally between 1.0 and 1.5cm, it not only has low weather resistance and short service life, but also is prone to leakage. Leakage affects use. [0003] At the same time, because the waterproof membrane has been used outdoors for a long time, the use environment is relatively harsh, it has to withstand the erosion of ultraviolet rays and various atmospheric pollutants for a long time, and it is easy to degrade; Sticky, so that the...
