Problems solved by technology

[0003] During the construction of TPO waterproof membranes, two methods of mechanical fixing and hot air welding are usually used, but the effect of mechanical fixing is poor, and it is difficult to completely fix the overlapping edges of the membrane without leaving gaps, so hot air welding has become the mainstream construction method

Abstract

The invention relates to the technical field of waterproofing, in particular to a flame-retardant TPO (thermoplastic polyolefin) waterproof roll and a preparation process thereof. The flame-retardant TPO waterproof rolll comprises the following components in parts by mass: 40-60 parts of rubber, 15-35 parts of thermoplastic polyolefin synthetic resin, 15-25 parts of a flame retardant, 10-25 parts of a modified filler, 0.1-0.5 parts of an antioxidant, 2-5 parts of a defoaming agent and 1-3 parts of argil. The preparation process of the TPO waterproof roll comprises the following steps of: S1, mixing the raw materials prepared according to the weight parts of the formula, putting the mixture into a stirring device, feeding the mixture into a feeding machine, and feeding the mixture into a hot air drying device for drying; S2, carrying out melting and plasticizing, and extrusion molding; S3, shaping a sheet; and S4, carrying out traction cooling, deviation rectification, edge cutting, tailoring and rolling. Aiming at the defects in the prior art, the waterproof roll prepared by the process can reduce the probability of fire disasters during construction, and is safe and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of waterproofing, in particular to a flame-retardant TPO waterproofing membrane and a preparation process thereof. Background technique [0002] TPO waterproof membrane is a new environment-friendly polymer waterproof material. Due to its excellent physical and mechanical properties, reliable installation and excellent performance confirmed by long-term use, TPO waterproof membrane has been widely recognized. In the single-layer roof waterproofing system, the TPO waterproofing membrane has the excellent weather resistance and low temperature performance of the EPDM waterproofing membrane and the excellent welding construction performance of the PVC waterproofing membrane, and the TPO waterproofing membrane does not contain chlorine and plasticizers. No harmful volatiles are produced during processing, so it has long-term weather resistance and thermal stability. Since the oxygen index (OI) of TPO is only 18...
