Description

Asphalt coating extrusion equipment for asphalt waterproof coiled material

Technical Field

The invention relates to the technical field of asphalt waterproof coiled material production equipment, in particular to asphalt coating extrusion equipment for asphalt waterproof coiled materials.

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.

The waterproof roll material is an unmodified waterproof roll material with the asphalt in the tire or a modified waterproof roll material with the asphalt in the tire. The production process of the waterproof roll material generally comprises the steps of dipping asphalt on base fabric of a tire, such as non-woven fabric, and the like, and then extruding the base fabric of the tire dipped with the asphalt to tamp the asphalt on the base fabric of the tire. Two procedures of pre-dipping and coating are needed during production; the pre-dipping has the function of soaking the pre-dipping asphalt into the tire base fabric, so that the tire base fabric can be completely soaked with the asphalt, and water channeling and layering of a finished product after the finished product is in contact with water are avoided; on one hand, the coating is to meet the requirement of certain thickness, and more importantly, to finally obtain a strict and uniform waterproof coiled material, however, the strict and uniform degree of the waterproof coiled material produced by the existing coating device is not high, and air bubbles are easily left, so that the production quality is not high, and the service life of the waterproof coiled material is influenced; in addition, child base itself has certain elastic deformation space, in case will appear contracting deformation by being dragged, because pitch has certain viscosity, the child base of coating pitch can produce stress when tensile to lead to child base and pitch layer to appear the contracting deformation of bigger degree, how reduce the shrinkage of coiled material, be present waterproofing membrane production line urgent need to solve waterproofing membrane's thickness change, the strict even degree is not high, and how reduce the problem of coiled material shrinkage.
