Problems solved by technology

The condensed SBS and APP overcome the resistance and float up, causing segregation and stratification, which destroys the stability of the modified asphalt system and seriously affects the modification effect of the modified asphalt
In addition, the anti-aging performance is improved by adding ultraviolet absorbers in this formula. Although the anti-aging performance has been improved compared with traditional asphalt shingles, it is still not ideal, and it is well known that ultraviolet absorbers are expensive, which increases the cost of asphalt shingles.
At the same time, the asphalt shingles of this patent also do not have the effects of fire retardant and heat insulation.

Abstract

The invention relates to a heat-insulation flame-retardant asphalt shingle and a preparation method thereof. The asphalt shingle comprises a glass fiber body, a modified asphalt coating, a facing material layer and an isolation material layer; the modified asphalt coating adopts the following raw material formula in percentage by weight: 30 percent to 50 percent of 10# petroleum asphalt, 5 percent to 10 percent of 90# road asphalt, 1 percent to 3 percent of a polyolefin processing modifier, 15 percent to 25 percent of magnesium hydroxide, 6 percent to 12 percent of rubber powder and the balance of filling; the facing material layer adopts the following raw material formula in percentage by weight: 30 percent to 40 percent of hollow ceramic microbeads, 2 percent to 5 percent of powder butadiene styrene rubber and the balance of color sand. The asphalt shingle disclosed by the invention has excellent fireproof, flame-retardant, heat insulation and heat preservation effects, aging resistance and low flexibility, has both decoration performance and attraction performance and is low in cost.

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 ...
