Description

TECHNICAL FIELD

[0001] The application relates to the technical field of waterproof roll processing, in particular to an immersion coating tank and an electric heating melting non-self-adhesive asphalt waterproof roll production device. BACKGROUND

[0002] Building waterproof materials can be divided into waterproof rolls, waterproof coatings, waterproof plugging materials and rigid waterproof materials, among which waterproof rolls are divided into two categories: modified asphalt waterproof rolls and polymer waterproof rolls, accounting for about 65%-70%, and the modified asphalt waterproof rolls account for 45-50%, so the modified asphalt waterproof rolls are the main force of building waterproof, because of their high cost performance.

[0003] Modified asphalt waterproof rolls are divided into self-adhesive asphalt waterproof rolls and non-self-adhesive asphalt waterproof rolls. The self-adhesive asphalt waterproof roll has adhesion at room temperature, and can be directly adhered to the base surface after the surface isolation material (film) is removed, and the roll-to-roll sealing is directly overlapped, without the need for open flame heating, that is, cold construction, which has natural advantages in closed space or poorly ventilated environment. The non-self-adhesive asphalt waterproof roll, as the name implies, refers to a roll that does not have adhesion at room temperature, mainly including elastomer modified asphalt waterproof roll (GB18242) and plastic body modified asphalt waterproof roll (GB18243), etc. This kind of material uses hot melt styrene-butadiene rubber (SBS) or atactic polypropylene (APP) modified asphalt to prepare asphalt coating material, which is prepared by immersion coating of polyester or glass fiber, and is covered with isolation film (such as shown in the drawing). Figure 1 Due to high-temperature combustion, smoke is serious, which seriously pollutes the environment. In some areas such as Beijing, Shandong and Chongqing, the use of hot melt method construction roll is prohibited in closed space or poorly ventilated environment. In some urban areas, in order to avoid affecting the living environment, even in non-closed space such as roof, the use of hot melt method is also prohibited. This is extremely unfavorable to the development of non-self-adhesive asphalt waterproof roll (mainly referring to elastomer modified asphalt waterproof roll and plastic body modified asphalt waterproof roll). In terms of physical properties, non-self-adhesive asphalt waterproof roll has high water pressure resistance and excellent waterproof performance, and has a history of more than 100 years in developed countries such as Europe and the United States. In China, it has also been used for 30 years since the 1990s. It is a reliable waterproof material, but its open flame heating construction causes serious smoke, which affects the environment and is not in line with the development direction of society.

[0004] The existing immersion coating tank can only coat ordinary asphalt waterproof roll. Therefore, the immersion coating tank needs to be improved by those skilled in the art. CONTENT OF THE UTILITY MODEL
