Production process and equipment of waterproof and anti-cracking polypropylene base cloth

Abstract

The invention discloses a production process of waterproof and anti-cracking polypropylene base cloth. The polypropylene base cloth is contained and is produced through steps as follows: S1, production of polypropylene base cloth skin; S2, smearing of an anti-cracking coating; S3, primary drying; S4, smearing of a waterproof coating; S5 secondary drying; S6 turning of the polypropylene base cloth skin; S7 winding up; S8, storage. The invention further discloses equipment for producing polypropylene base cloth. The equipment comprises an operating table, wherein wind-up rolls are arranged at two ends of the operating table, and coating storage grooves directly face a coating roll I and a coating roll II; the structure is simple, the polypropylene base cloth has the anti-cracking function and the service life of the polypropylene base cloth in cold winter is further guaranteed by adding and smearing the anti-cracking coating, the surface of the polypropylene base cloth is smeared with the waterproof coating, and accordingly, the waterproof capability of the polypropylene base cloth is further improved.

Description

technical field [0001] The invention relates to the technical field of polypropylene base cloth, in particular to a production process and equipment for a polypropylene waterproof and crack-proof base cloth. Background technique [0002] Polypropylene base cloth refers to functional special materials that can save energy, reduce consumption, protect the environment and restore the environment in engineering construction, especially in infrastructure projects such as railways, highways, water conservancy, and mines that have great damage to the environment. , is known as the fourth type of green new building material after the three traditional materials of cement, steel bar, and wood. However, some polypropylene base fabrics do not have the function of waterproofing and anti-cracking. In cold winter or other weather with a lot of rain, it is easy to cause damage to bridges and other buildings, and the traditional polypropylene base fabric has a single function and cannot be ...

AI Technical Summary

Problems solved by technology

However, some polypropylene base fabrics do not have the function of waterproofing and anti-cracking. In cold winter or other weather with a lot of rain, it is easy to cause damage to bridges and other buildings, and the traditional polypropylene base fabric has a single function and cannot be used very well. construction of protection projects, etc., which in turn affects the service life of buildings and wastes resources, which is contrary to the subject of conservation and environmental protection advocated now.
