Description

technical field

[0001] The invention relates to an asphalt tile and a preparation method thereof. Background technique

[0002] As an easy-to-construct roof waterproof material, asphalt tiles are mainly used in various types of residential buildings, especially in the slope roof waterproofing projects of multi-storey houses and villas.

[0003] In recent years, due to changes in architectural design and the use of new building components, higher and higher requirements have been placed on roof waterproofing materials. In September 2009, the Ministry of Public Security issued Document No. 46 requiring the exterior facades including roofs to reach the fire rating of B1. Document No. 65 in March 2011 required even stricter requirements, including the fire rating of high-rise buildings and other building materials being adjusted to A class. At the same time, the "Twelfth Five-Year Plan" Comprehensive Work Plan for Energy Conservation and Emission Reduction issued by the State ...
