[0002] Waterproof materials occupy a very important position in building materials. The quality of waterproof materials directly affects the quality of the entire construction project. The traditional waterproof materials are mainly petroleum asphalt linoleum, but this kind of material has its own shortcomings that are difficult to overcome. After being gradually eliminated, organic polymer materials were used in the construction field, and new polymer waterproof materials developed rapidly, such as modified asphalt linoleum, synthetic rubber series, and polymer waterproof coatings. Traditional waterproof materials have been greatly improved. People have also designed waterproof materials that bond layered waterproof materials with laminated structures. This type of waterproof membrane is widely used in existing construction projects, but with the development of society , the change of people's concept of building waterproofing has changed from a single economic cost concept to a functional concept. At the same time, the cost and service life of the waterproof project have also been considered. Therefore, the existing waterproof rolls have the following defects: First, this type of waterproof roll The pattern of the material is very simple, that is, black and white monochrome, which is not beautiful, and cannot meet the beautification and aesthetic requirements of modern urbanization; secondly, the stain resistance and weather resistance of this type of waterproof membrane are relatively poor, especially in the north where the temperature difference is large. In other places, after a period of use, the underlying plasticizer migrates upwards and seeps back to the surface, so the stain resistance and weather resistance are relatively poor. In addition, its reliable waterproof life is relatively short

Embodiment 1
[0014] The present invention comprises the following steps:
[0015] The first step is to blow the PE film, and add powdered UV absorber during the blowing process;
[0016] In the second step, the surface of the PE film completed in the first step is electrostatically treated at 35°C for 0.05s;
[0017] The third step is to print a color pattern on the surface of the PE film completed in the second step to prepare a PE color film;
[0018] In the fourth step, one side of the PE color film completed in the third step is compounded with a layer of PET film with an adhesive to obtain a color laminated film;
[0019] In the fifth step, after the color laminated film produced in the fourth step is cured at a constant temperature of 65°C for 48 hours, it can be combined with the main layer of the modified bitumen waterproof membrane prepared by the prior art.

Abstract
The invention discloses a printing synthesis method of a color film for modified asphalt waterproof coiled materials, which comprises the following steps: 1. blowing a PE (polyethylene) or PET (polyethylene terephthalate) film while adding a weather-resistant assistant; 2. carrying out electrostatic treatment on the surface of the PE or PET film at 35-50 DEG C for 0.05-0.15 second; 3. printing a color pattern on the surface of the PE or PET film; 4. compounding a PET film on one surface of a color film by using an adhesive to obtain a color laminate film; and 5. carrying out constant-temperature curing on the color laminate film at 45-65 DEG C for 30-48 hours, thereby performing compounding application. The color film can satisfy the demand for beautiful appearance in the actual construction process by printing the beautiful pattern on the surface layer, thereby greatly enhancing decoration performance of the product. The weather-resistant assistant is added into the color film, and the PET film is compounded, so the color film has higher pollution resistance and weather resistance and can prolong the actual waterproof service life of the modified asphalt waterproof coiled material.
