Abstract

The invention relates to a production process of a waterproof roll material for a greenhouse. The production process of the waterproof roll material for the greenhouse belongs to the technical field of production processes of the waterproof roll material, and comprises the following steps of uniformly mixing a polymer modifier and an anti-aging agent, melting asphalt, and adding a plasticizer for mixing with the asphalt; cooling polymer modified asphalt, passing the polymer modified asphalt through a cooling section of a main extruder, and gradually reducing the temperature from 185 to 200 DEG C to 80 to 120 DEG C, wherein the tail end of the cooling section is provided with vacuum exhaust; entering the polymer modified asphalt into a net changing section, coating a waterproof roll material base material with the polymer modified asphalt through a flat mold head; and compounding an isolation protection layer to the surface of the polymer modified asphalt through a pressure roller. By adopting the process provided by the invention, the production efficiency is greatly improved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a production process of waterproof coiled material for greenhouses, and belongs to the technical field of production process of waterproof coiled material. Background technique [0002] Bituminous waterproofing membranes have been widely used, especially in the use of greenhouses. However, due to the significant temperature sensitivity of asphalt (easy to soften at high temperature and easy to crack at low temperature), low mechanical properties and elastic properties, it is easy to age and lead to cracking and loosening. Significant thermal sensitivity prevents asphalt mixtures from exhibiting good performance at high and low temperatures, and asphalt properties must be modified to enhance product performance. [0003] By mixing polymers into asphalt, it can significantly improve the high-temperature and low-temperature performance of asphalt, improve the elastic-plastic properties of asphalt, increase durability and anti-agi...
