Abstract

The invention provides a waterproof coiled material with high flame retardance and a preparation method. The waterproof coiled material comprises a glass fiber mat, wherein waterproof layers are arranged on the upper and lower surfaces of the glass fiber mat; flame retardant layers are arranged on the surfaces of the waterproof layers; the glass fiber mat is an alkali glass fiber mat; the waterproof layers are SBS modified asphalt layers; the flame retardant layers are graphene modified polyurethane coatings. The preparation method comprises the following steps: (1) preparation of SBS modified asphalt; (2) preparation of a polystyrene / graphene nanocomposite; (3) preparation of the waterproof material. The waterproof coiled material and the preparation method have the beneficial effects that by adopting the polystyrene / graphene nanocomposite layers as the flame retardant layers, the flame retardance of the polymer modified asphalt waterproof coiled material can be greatly improved, so the waterproof coiled material meets the requirements of the construction industry at present, and the waterproof coiled material is simple in preparation process and has higher application value.

Description

technical field [0001] The invention relates to a waterproof material for construction engineering, in particular to a highly flame-resistant waterproof coiled material. Background technique [0002] Waterproof materials are widely used in the engineering waterproofing of roofs and basements of various industrial and civil buildings, as well as engineering waterproofing of municipal and water conservancy facilities such as subways, tunnels, highway bridges, etc. The current waterproof membranes have poor resistance to damage and are prone to puncture Or tear phenomenon, need to spend manpower, material resources to repair, shorten the service life of waterproof material, cause the waste of resources and funds. [0003] Waterproof membrane is a kind of building material commonly used in building construction. In the construction of road bridges, roofs or buildings that need waterproofing, waterproof membranes need to be laid in advance. At present, the commonly used waterpro...
