Problems solved by technology

A large number of spraying polyurea waterproofing methods are used, which effectively solves the requirement of continuous waterproofing under the base plate, but in the process of application, some problems are also found: ①High engineering cost
②Many influencing factors
③Polyurea spraying construction requires one-time complete coverage of the bridge deck, and the follow-up process will inevitably cause certain damage to the constructed polyurea waterproof layer, affecting the waterproof effect

Abstract

The invention discloses a compound type chlorinated polyethylene waterproof roll and a preparation method of the compound type chlorinated polyethylene waterproof roll, which solve the problems in the construction and use process of spraying polyurea waterproofing coating in the prior art. The adopted technical scheme is as follows: the compound type chlorinated polyethylene waterproof roll comprises the following components in parts by weight in the formula: 90-120 parts of chlorinated polyethylene, 2-30 parts of filling-reinforcing agent, 10-45 parts of softening plasticizer, 0.1-2 parts of phenolic antioxidant, 3-10 parts of heat stabilizer, 0.4-1.5 parts of light stabilizer, 3-8 parts of lubricant and 0.5-3 parts of other agents; the phenolic antioxidant is blended by 30-40% of antioxidant 1076 and 60-70% of antioxidant DSTDP; and the other agents are processing-modifying agents ACR-201 or ACR-301.

Description

technical field [0001] The invention relates to a novel wide-width waterproof coiled material which can replace spraying polyurea waterproof coating, in particular to a composite chlorinated polyethylene waterproof coiled material and a preparation method thereof. Background technique [0002] The construction industry in the 21st century has entered an era of rapid development, requiring beautiful and durable buildings, and building waterproof materials must also have the characteristics of light weight, high strength and long service life. At present, the concrete waterproof layer is an important technical means to improve the durability of building structures. There are many cases of bridge deck or roof water seepage and steel bar corrosion due to waterproof failure, which directly affects its service life. At present, the most widely used waterproof material on high-speed railway bridges is spraying polyurea waterproof coating, which is a kind of polyurea elastomer. This...
