Problems solved by technology

[0005] However, the inventors have found that there are still some defects in the above disclosed documents, and their common shortcomings are: the first is that the above equipment has complex structure, high cost, inconvenient use and maintenance, and is only suitable for single-sided composite waterproof rolls. When it is necessary to process double-sided composite waterproof membranes, the processing is difficult and the process is cumbersome
Therefore, the thickness can only be increased on the layered structure of the waterproof membrane to achieve strength. However, during the composite production process, asphalt is easy to leak from the phase material and bond with the two rollers of the composite pressure roller, causing pollution , affecting the normal operation of production equipment
In addition, due to the high viscosity of the modified asphalt, it is not easy to be dispersed, and if the temperature is uneven, it is more likely to cause uneven thickness of the material

Embodiment 1

[0038] Scratching points: 1. There is a scraping point on the left and right sides. There are two large rollers 18 of the same size at the scraping point, and the length can be determined according to the product specification. The lower roller drives the main shaft to rotate through the motor, and the upper roller can rotate or not, or manually rotate. 2. The temperature of the modified asphalt is controlled at about 170°C. After it is placed at the scraping point, the lower roller rotates, and the upper roller does not rotate or rotates slowly, thereby driving the upper coating film 16, the lower coating film 21 and the isolation film 15 forward Movement, and "bring" the modified material out, similar to calendering, but there is almost no pressure between the two rollers, so it is a shearing movement. It is equivalent to scraping the modified material on the isolation film, which not only ensures that the modified material can be effectively scraped on the isolation film, ...

Embodiment 2

[0041] Similar to the first one, just change the two large rollers at the scraping point into different large rollers 18 and small rollers 25 pairs of rollers, and the film coating system is the same.

[0042] Scratching points: 1. There is a scraping point on the left and right sides. There are two rollers at the scraping point, one big and one small, and the length can be determined according to the product specification. The big roller drives the main rotation through the motor, and the small roller can rotate or not, and it is manually rotated. 2. The temperature of the modified material is controlled at about 170°C. After it is placed at the scraping point, the lower roller rotates, and the upper roller does not rotate or rotates slowly, thereby driving the upper coating film 16, the lower coating film 21 and the isolation film 15 forward Movement, and "bring" the modified material out, similar to calendering, but there is almost no pressure between the two rollers, so i...

Embodiment 3

[0045] The knife coating point consists of a large roller 18 and a rolling plate 26 . Scrape by traction.

[0046] Scratching points: 1. There is a scraping point on the left and right sides. The scraping point is made up of large roller 18 and rolling plate 26, and the length can be determined according to product specifications. The roller drives the main rotation through the motor, and the steel plate does not rotate. 2. The temperature of the modified material is controlled at about 170°C. After it is placed at the scraping point, the scraping roller rotates, and the coating counter-roller 22 at the coating point 20 drives the coating 16. The lower covering film 21 and the isolation film 15 move forward and "bring" the modified material out, which is a shearing movement. It is equivalent to scraping the modified material on the isolation film, which not only ensures that the modified material can be effectively scraped on the isolation film, but also ensures that the iso...

Abstract

The invention discloses a production method and equipment for a double-sided adhesive asphalt waterproof coiled material of a macromolecular tire. The production method comprises processes of material putting, modified asphalt scrape-coating, film covering and coiling, wherein the material putting process is used for putting molten modified asphalt into a scrape-coating system; the scrape-coatingprocess adopts a device for scrape-coating the modified asphalt leftwards and rightwards, and then carries out double-sided roller pressing and film covering to form the double-sided adhesive waterproof coiled material; the film covering process carries out double-sided film covering; the coiling process is carried out after the double-sided film covering is carried out; and a double-sided rollerfor scrape-coating the modified asphalt is provided with a thermostatic device. The equipment adopted for the production of the double-sided adhesive of the macromolecular tire comprises a material putting system and a scrape-coating system, wherein the material putting system adopts a circulating loop for a modified material by virtue of a motor and a pump. The production method and the equipment have the characteristics of simple structure, low cost, high production efficiency, wide purposes and the like.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to a production method and equipment for a double-sided asphalt waterproof coiled material with polymer tires. technical background [0002] Some current bitumen waterproofing membranes use a layered structure to increase strength. When this kind of waterproof membrane is produced, the composite counter-pressure roller is used as the forming machine. The two sides of the composite counter-pressure roller are fed with two layers of cloth through the cloth unfolding device, and the asphalt is input between the two layers of cloth through the asphalt conveying device. The fabric and the asphalt in the middle are pressed together by a composite counter-pressing roller, and the scraped modified asphalt is scraped at least twice before and after to become a high-strength waterproof membrane. The open literature also reports some production equipment of waterproof membranes, such as: [00...
