Preparation method of polymer waterproof coiled material

Abstract

The invention provides a preparation method of a high-molecular waterproof coiled material. The preparation method comprises the following steps: step S1, pre-oil-soaking treatment of tire base cloth; s2, carrying out cooling treatment on the tire base cloth; s3, preparing a polymer composite waterproof layer; s4, adhering a polymer composite waterproof layer; s5, adhering an isolating membrane; the prepared high-molecular coiled material comprises tire base cloth, high-molecular composite waterproof layers are adhered to the upper surface and the lower surface of the tire base cloth, isolating membranes are further adhered to the high-molecular composite waterproof layers, and the high-molecular composite waterproof layers are prepared from, by weight, 100 parts of high-density polyethylene and 15-20 parts of POE resin. The invention discloses a high-temperature-resistant adhesive which is prepared from the following components in parts by weight: 40-50 parts of asphalt, 10-15 parts of filling master batch, 3-5 parts of a cross-linking agent, 20-25 parts of tackifying resin, 15-20 parts of softening oil and 3-5 parts of dibromocyanoacetamide. The invention provides the preparation method of the high-molecular waterproof coiled material which is good in chloride ion penetration resistance, good in tensile property and resistant to salt and alkali.

Description

technical field [0001] The invention relates to the technical field of waterproof rolls, in particular to a preparation method of a polymer waterproof roll. Background technique [0002] Solving the corrosion problem of steel bars is the key to improving the durability of buildings, and the steel bars of buildings are mainly eroded by chloride ions. Therefore, we need a waterproof membrane that can effectively resist the penetration of chloride ions, which can be installed on the water-facing surface of concrete. , in order to prevent the corrosion of concrete such as chloride ions. The traditional waterproof membrane also has a certain resistance to salt and alkali, but in actual use, the waterproof building in coastal and high salinity areas still has the problem of salt damage. Therefore, the preparation of specialized salt and alkali-resistant polymer waterproof membrane importance is increasing day by day. [0003] Therefore, it is necessary to study a preparation met...
