Flame-retardant TPO (thermoplastic polyolefin) waterproof coiled material and preparation method thereof

Abstract

The invention discloses a flame-retardant TPO (thermoplastic polyolefin) waterproof coiled material which is of a three-layer structure. The upper surface and the lower surface of the waterproof coiled material are flame-retardant TPO coiled material layers, a polyester fiber mesh grid fabric reinforced layer is arranged in the middle of the waterproof coiled material, the TPO coiled material layer of the upper surface is white, the flame-retardant TPO coiled material layer takes thermoplastic polyolefin synthetic resin materials combining ethylene propylene rubber and polypropylene as base materials and takes flame-retardant mixture as an auxiliary, safety of a product in the storage, transportation and use process is guaranteed, the weather resistance and the color retaining performanceof the product are guaranteed by cooperatively using anti-aging agents, anchoring agents, bridging agents, dispersing agents, softening agents and toners, so that the prepared waterproof coiled material is good in flame resistance, combustion performance level reaches non-combustible level, the waterproof coiled material has the advantages of high reflectivity, excellent energy-saving effect and pollution resistance. The flame-retardant mixture is mixture of dimethyl methylphosphonate and micro-encapsulation red phosphorus, and the weight ratio of the dimethyl methylphosphonate to the micro-encapsulation red phosphorus is 1:2.

Description

technical field [0001] The invention relates to a polymer waterproof coiled material, in particular to a flame-retardant thermoplastic polyolefin TPO waterproof coiled material and a preparation method thereof, belonging to the field of waterproof chemical materials. Background technique [0002] With the improvement of construction technology, the demand for waterproof materials for construction projects is also increasing, and the quality requirements are also getting higher and higher. Therefore, the promotion and application prospects of new polymer waterproof membranes are also becoming wider and wider. Polymer waterproof membrane is a new type of building material. It is light, high-strength, low-energy and multi-functional in line with the development trend of building material innovation. Common varieties include PVC waterproof membrane, EPDM waterproof membrane, CPE waterproof membrane and TPO waterproof membrane. Coil. Among the current waterproof materials, the m...

Problems solved by technology

[0005] Although the flame-retardant thermoplastic polyolefin waterproof membrane of the above-mentioned patent has the highest level of combustion performance up to grade A, the fillers in it have not been modified, and there will be obvious disadvantages when filled with polyolefin: first, the surface is hydrophilic and oleophobic, The dispersion in polyolefin is poor; the second is the poor bonding force between calcium carbonate and polyolefin body, which can only play a role of compatibilization. When filling with high proportion of calcium carbonate, the performance of polyolefin material will drop sharply, so that the product is difficult to be processed. and use
