Problems solved by technology

However, asphalt cannot fully meet these requirements, resulting in serious leakage of asphalt waterproof materials and short service life.
Moreover, the existing modified asphalt only by adding materials has poor compatibility between the modifier and the asphalt, and is easy to delaminate, coagulate or phase separate, and the properties of the asphalt cannot be effectively improved.

Abstract

The invention relates to the technical field of waterproof materials, in particular to a butyl rubber modified asphalt waterproof material as well as a preparation method and application thereof. Thebutyl rubber modified asphalt waterproof material is mainly prepared from the following components in percentage by weight: 40-60% of asphalt, 8-20% of butyl rubber, 2-4% of butadiene styrene rubber,6-25% of softening oil and 10-36% of talcum powder. According to the butyl rubber modified asphalt waterproof material disclosed by the invention, butyl rubber is added for modifying, so that ageing resistance and stable performance of asphalt are effectively improved, and embrittlement of the asphalt is improved; a little butadiene styrene rubber is added, so that strength of the waterproof material is improved; and butyl rubber and butadiene styrene rubber are good in compatibility, can form a homogenized mixed system with asphalt, and effectively improves performances of the asphalt, so that the waterproof material has the advantages of being resistant to a high temperature, a low temperature, ageing, corrosion and water; and meanwhile, low-temperature elasticity and plasticity as wellas high-temperature strength and stability are met.

Description

Technical field [0001] The present invention relates to the technical field of waterproof materials, in particular to a butyl rubber modified asphalt waterproof material and a preparation method and application thereof. Background technique [0002] Waterproof materials are a very important item in building products, which are related to the use value, use conditions and sanitary conditions of the building, and affect people's production activities and the quality of work and life. The quality of waterproof materials directly affects the function and service life of the building. With the continuous improvement of social living conditions, people pay more and more attention to their quality of life, and the requirements for waterproof conditions are constantly increasing. In recent years, with the development of social science and technology, new waterproof products and their engineering application technologies have developed rapidly. [0003] Waterproof materials are mostly use...
