Problems solved by technology

However, once its flame-retardant waterproof membrane is burned, as the heat is transferred to the base layer, the base layer or the underlying structure will heat up, and the combustion will spread to the base layer and structure, resulting in structural failure.
The flame-retardant waterproof membrane only increases the burning point, and does not have the function of preventing the burning from spreading

Abstract

The invention belongs to the functional and high-performance research field of universal materials, namely a functional organic polymer matrix composite system and particularly relates to an intumescent fire resistant type waterproof roll and a preparation method thereof. The technical scheme adopted by the invention is as follows: the intumescent fire resistant type waterproof roll is composed of a perchloride polymer, a toughening polymer, a compound stabilizer, a lubricant, a plasticizer, a processing aid, a thermal expander, a sintering carbon-forming agent, a catalysis dehydrating agent, a smoke abatement fire retardant, high-temperature resistance fiber and a coupling agent. The intumescent fire resistant type waterproof roll provided by the invention has waterproof and fireproof double functions and is particularly suitable for the application with waterproof and fireproof requirements.

Description

technical field [0001] The invention belongs to the field of functional and high-performance research and development of general materials, is a functional organic polymer-based composite material system, and particularly relates to an intumescent fire-retardant waterproof coiled material and a preparation method. Background technique [0002] The progress of construction technology is developing in the direction of industrialization, modernization and industrialization, followed by the rapid increase in the use of steel structure buildings and metal roofs, and the use of metal structures and roofs has become the most obvious feature of construction technology progress. Most steel structures or metal roofs are accompanied by thermal insulation layers. The thermal insulation materials that can meet the relevant standards for building thermal insulation are basically combustible materials. [0003] The technical measure adopted by the existing flame-retardant waterproof membra...
