Abstract

The invention relates to a vulcanized ethylene-octene copolymer waterproof coiled material and a production method thereof. The vulcanized ethylene-octene copolymer waterproof coiled material comprises a base layer, the base layer takes the ethylene-octene copolymer as a main raw material, and other auxiliary materials comprise fast extruding furnace black, calcium carbonate, ultrafine powdered steatile, polyethylene glycol and an antioxidant. By taking 100 parts of the ethylene-octene copolymer as a reference, the vulcanized ethylene-octene copolymer waterproof coiled material comprises the following components by weight part: 50-110 parts of fast extruding furnace black, 30-70 parts of ultrafine powdered steatile, 5-10 parts of calcium carbonate, 20-60 parts of plasticizer, 2-10 parts of polyethylene glycol, 1-6 parts of dicumyl peroxide, 0.5-2.75 parts of cross-linking agent and 1-3 parts of antioxidant. The ethylene-octene copolymer is crosslinked by dicumyl peroxide, complete crosslinking of the molecular chain of the ethylene-octene copolymer waterproof coiled material can be realized, thermal stability performance of the waterproof coiled material is increased, the relative molecular mass distribution of the ethylene-octene copolymer is narrow, high extrusion capacity is realized, production efficiency is greatly increased, and production cost is effectively reduced.

Description

1. Technical field [0001] The invention relates to the field of building waterproof materials, in particular to a vulcanized ethylene octene copolymer waterproof coiled material and a production method thereof. 2. Background technology [0002] At present, the polymer membrane with the best comprehensive performance is recognized in the world as the vulcanized EPDM waterproof membrane, but because EPDM is a non-polar and difficult-to-stick material, the vulcanized EPDM waterproof Coil materials have been difficult to be widely used due to adhesion problems. With the advancement of science and technology, many polymer materials with excellent performance have been born. Among them, the molecular structure of ethylene octene copolymer is similar to that of EPDM rubber, so it can be used in waterproof materials. In recent years, some public documents have also disclosed some technologies in this area, such as: [0003] 1. Chinese patent ZL98102553.6, the patent name is: "A The...
