Abstract

The invention provides a high-weather-resistance TPO waterproof coiled material and a preparation method and application thereof. The high-weather-resistance TPO waterproof coiled material is prepared from the following raw materials in percentage by weight: 75-90% of TPO resin; 7-15% of a filler; 2-8% of an opacifying agent; 0.1-0.4% of an ultraviolet light absorber; 0.5-1% of a light stabilizer; and 0.4-0.6% of an antioxidant. According to the invention, multiple defense lines and multiple systems are constructed, so that the TPO waterproof coiled material can keep long-term and efficient weather resistance in the use process.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled materials, and relates to a highly weather-resistant TPO waterproof coiled material and a preparation method and application thereof. Background technique [0002] TPO waterproof membrane is thermoplastic polyolefin waterproof membrane. It is a thermoplastic polyolefin (TPO) synthetic resin that combines ethylene-propylene rubber and polypropylene as the base material, adding antioxidants, anti-aging agents, softeners and other additives. Made of new waterproof membrane. The exposed TPO waterproof membrane has very strict requirements on weather resistance. Ultraviolet radiation will cause free radicals inside the TPO waterproof membrane, which will accelerate the aging of the product, and strong sunlight will cause the temperature of the roof to rise and damage the membrane. Thereby reducing the service life of the coil. At present, the exposed TPO waterproof membrane generally has in...
