Problems solved by technology

[0004] (1) At present, my country has not formulated a unified test standard for flame-retardant asphalt materials
[0005] (2) The use of some flame retardants will cause greater harm to the human body and the environment, so attention should be paid to the use and development of environmentally friendly flame retardants in the research of flame-retardant asphalt
Prior to this, there was no large-scale production of flame-retardant polymer-modified bitumen waterproof membranes in China.

Abstract

The invention provides a flame-retardant polymer modified asphalt waterproof roll, which is in a multi-layer composite structure, a middle layer is a non-woven fabric layer, and an upper surface layer and a lower surface layer are flame-retardant polymer modified asphalt coatings, wherein each flame-retardant polymer modified asphalt coating comprises the following components in parts by weight: 100 parts of heavy duty road petroleum asphalt, 15-30 parts of composite flame retardant which further comprises 3-7 parts of decabromodiphenylethane, 5-10 parts of diantimony trioxide, 3-5 parts of magnesium hydroxide, 3-5 parts of aluminum hydroxide and 1-3 parts of zinc borate, and 15-30 parts of polymer modifier which further comprises 10-20 parts of butadiene-styrene-butadiene copolymer, 2-5 parts of styrene-butadiene rubber and 2-5 parts of atactic polypropylene. The invention further provides a preparation method of the roll.

Description

technical field [0001] The invention relates to a waterproof material for construction engineering, in particular to a flame-retardant polymer modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] In building fire safety, the burning of asphalt is an unavoidable problem. Because asphalt is easy to burn when it comes into contact with the fire source, and it will melt, drip, and flow when it burns, causing the fire to spread and expand. During the combustion process, asphalt will also decompose flammable gases such as hydrogen and methane, and the combustion of these flammable gases will intensify the fire. At present, some manufacturers and scientific research institutions at home and abroad have begun to study and conduct trial production of flame-retardant asphalt to meet the demand for flame-retardant asphalt in construction projects. [0003] In consideration of the flammability and safety of asphalt, my country has...
