Problems solved by technology

This kind of manufacturing process makes the self-adhesive adhesive and the main material layer bond firmly, and it cannot be peeled off by artificial methods
[0005] The waterproof coiled material reported in the above-mentioned publication 1 has improved the bonding performance with wet concrete in some aspects, and it is also mentioned that the resin adhesive layer achieves waterproof effect due to the chemical reaction with concrete, but the use of high-density polyethylene membrane coiled material The strength is low when subjected to high temperature; the self-adhesive glue and polymer self-adhesive waterproof membrane composition reported in Document 2 have insufficient bonding force with the concrete base surface, the bonding force is not durable, and the operation is not easy to master

Abstract

The invention discloses a wet-laying and pre-laying waterproof roll which is made by the following processes: dipping and coating a modified asphalt compound on a blank body, controlling the thickness and sizing, coating a membrane, rolling, and the like, wherein the modified asphalt compound contains modified asphalt, a plasticizer, an antioxidant, a functional auxiliary agent and a filling gent. A preparation method of the waterproof roll comprises the following steps: putting substrate asphalt in a reaction pot, adding a thickening agent, irregular polyethylene and styrene-polybutadiene-styrene segmented copolymer, evenly mixing, heating and stirring for 1.5-2 hours, then reducing the temperature to about 180 DEG C, adding padding, the plasticizer, the antioxidant and the functional auxiliary agent into the reaction pot and stirring for 0.5-1h, evenly mixing and modifying, then conveying into a colloid mill for repeatedly milling to the material, then dipping and coating the modified asphalt on the blank body, controlling the thickness, sizing, coating the membrane and rolling, and finally preparing the waterproof roll which has excellent performance and can carry out chemical bonding and physical crosslinking synergism with the concrete, namely, a CPS waterproof roll for short.

Description

technical field [0001] The patent of the present invention relates to a waterproof coiled material, especially a wet-laid pre-paved waterproof coiled material capable of physically adsorbing mortise and tenon with concrete and at the same time chemically crosslinking and firmly bonded to concrete and its production method. Background technique [0002] Common waterproof materials mainly include coatings, coiled materials, sealants, and waterstops. The most used waterproof coatings are polyurethane, neoprene latex, and polymer cement waterproof coatings. They all have common problems in the use of coatings: such as construction The thickness is not easy to control; it is firmly combined with the base surface, and it is prone to "0" stretching and cracking due to cracks in the base surface; most coatings are not easy to use in long-term water immersion environments, and are not easy to use in places exposed to sunlight; especially polyurethane The waterproof coating used for c...
