Abstract

Disclosed are a flame-retardant modified bitumen waterproof coiled material coating material and a flame-retardant self-adhesive bitumen waterproof coiled material and preparation method thereof. Thewaterproof coiled material includes a metal glass fiber grid composite flame-retardant layer, a flame-retardant modified asphalt layer, a glass fiber tire flame-retardant layer, a flame-retardant self-adhesive asphalt layer, and an isolation layer that are sequentially arranged from top to bottom. The invention is thin and adapts to the trend of building energy saving and carries out cold self-adhesive construction, and has high bonding strength and good heat resistance. There is no need to use open flame for construction. Construction is convenient, safe and environmentally friendly. The invention has excellent waterproof and flame-retardant performance, is multi-layer synergistic flame-retardant, has fire-proof grade B1, and stops burning after leaving the fire source. The invention is especially suitable for building waterproofing with high waterproof requirements and can be flame-retardant from the inside to the outside and from the outside to the inside. It has excellent flame retardant performance and wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of building waterproof membranes, and more specifically relates to a flame-retardant modified asphalt waterproof membrane coating material, a flame-retardant self-adhesive asphalt waterproof membrane and a preparation method thereof. Background technique [0002] The self-adhesive membrane construction does not need to use open flames, the construction is convenient, and the waterproof effect is good. It is an environmentally friendly waterproof material and is widely used in waterproof projects for various civil and industrial buildings. Poor, the waterproof layer is easily damaged in high temperature environment, thus losing the waterproof effect, and the ordinary asphalt membrane does not have the characteristics of flame retardancy, so it cannot be used in some waterproof parts of buildings with high fire protection requirements. At this stage, building energy saving is the development trend. Waterproofi...
