Background

The asphalt waterproof coiled material is a coiled material made of asphalt material, base material and surface spreading anti-sticking material, also called asphalt felt, and is commonly used for a pasting type waterproof layer. The asphalt waterproof coiled material comprises a filled coiled material and a non-filled coiled material. The roll-shaped material is made by impregnating base materials such as thick paper or glass fiber cloth, asbestos cloth, cotton and linen fabrics and the like with petroleum asphalt and is called as a base coiled material; asbestos, rubber powder, etc. are mixed into asphalt material, and the rolled material is called rolled coiled material, i.e. tubeless coiled material.

The modified asphalt waterproof coiled material is commonly called modified asphalt felt, and is a curlable sheet-like waterproof material which is prepared by taking a glass fiber felt, a polyester felt, a jute cloth, a polyethylene film, a polyester non-woven fabric, a metal foil or two composite materials as a base, taking synthetic high molecular polymer modified asphalt and oxidized asphalt with the mixing amount of not less than 10% as dip-coating materials and taking powder, sheet and granular mineral materials, synthetic high molecular films and metal films as covering materials. Due to inherent disadvantages of low softening point, high penetration and low temperature brittleness of asphalt itself, the application range of the asphalt is limited when the asphalt is used as a waterproof material. After the asphalt is modified by adding the high molecular polymer, the performances are greatly improved, the weather resistance, the temperature sensitivity (high-temperature characteristic and low-temperature flexibility) and the adaptability to substrate cracking are obviously improved, and the waterproof material prepared by using the modified asphalt is realistic and possible from the traditional 'heavy, thick, long and big' era to the 'light, thin, short and small' industrialized era.

Wherein, the waterproof coiled material is really formed only after the coiled material which is coated with the coating is subjected to sand coating or film coating. The currently common coating process is as follows: the method is characterized in that a pre-soaked base fabric is introduced into an asphalt coating material pool by using a press roller, and the base fabric leaves the material pool after being adhered with the asphalt coating material on the two sides. Accordingly, there is a need for improvements in existing coating devices. According to different treatment modes of sand coating or film coating on the surface of the waterproof roll, the waterproof roll is divided into a double-sided sand product, a double-sided film product and a single-sided sand product, different devices are generally required to be used for producing different waterproof roll products, the device universality is not high, and the general type film coating and sand coating device which can be suitable for different types of waterproof rolls simultaneously can greatly improve the practicability of roll production equipment.

When the two-sided sand-lined product of production, first reverse conveying roller also once compressed tightly the sand that coats the sand surface through the extrusion effort between roller and the coiled material when going on the upset to the coiled material, has improved the steadiness of sand and the quality of coiled material product simultaneously. The air outlet can make the temperature on pitch coiled material surface promote more evenly towards parallel arrangement, consequently the effect of sand-lined is also better.

The front blower set comprises two sets of blowers which are arranged up and down, namely an upper blower and a lower blower respectively, the waterproof coiled material passes through the space between the upper blower and the lower blower, the air outlet of the upper blower is inclined and aligned with the upper surface of the waterproof coiled material downwards, and the air outlet of the lower blower is inclined and aligned with the lower surface of the waterproof coiled material upwards. In the technical scheme, the air outlet is obliquely arranged towards the surface of the coiled material, so that the moisture on the upper surface and the lower surface of the coiled material in transmission can be removed by the air blown out from the front air blower set like an oblique scraper, and the drying efficiency is improved.

Compared with the prior art, the invention has the beneficial effects that: the waterproofing membrane that this equipment was made need not to impress in the pitch coating pond at coating in-process child base cloth, and child base cloth is not in and continuously pulls the state, consequently tension big, the serious condition of shrink in back end process can not appear, simultaneously, highly changes the contact condition of coiled material surface and cooling water through the bearing roller of adjusting the bearing coiled material for this equipment can adapt to the production of different types of coiled material products, has improved coiled material production facility's practicality, reduce cost and save space.
