Problems solved by technology

However, in actual use, melamine will decompose at a pressure melting point of 354°C, and melamine will decompose at high temperature to produce cyanide gas, which is a highly toxic gas. While achieving flame retardancy, it will produce toxic smoke with severe toxicity. Seriously affect the health in use

Abstract

The invention discloses a flame retardant coiled material. The flame retardant coiled material comprises the following components in parts by weight: 80 to 120 parts of highchlorinated polymer, 10 to 30 parts of magnesium aluminum alloy, 3 to 5 parts of toughened polymer, 1 to 3 parts of a dispersing agent, 0.5 to 2 parts of a silane coupling agent, 2 to 6 parts of organic silicon resin, 1 to 5 parts of a modifier, 1 to 5 parts of carboxymethylcellulose, and 1 to 5 parts of a compound stabilizer. The invention further discloses a preparation method of the flame retardant coiled material. The flame retardant coiled material ensures that inorganic materials are compounded with organic materials, improves the fire resistance and the flame retardant property of a highchlorinated polymer coiled material, guarantees the mechanical property and the water resistance of the highchlorinated polymer coiled material, with the combustion performance capable of reaching level A2, and has a good application prospect.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a flame-retardant coiled material and a preparation method thereof. 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, and waterproof membranes 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 membrane is to use a flame retardant in the material components, and as its content reaches a certain requirement, the flame-retardant performance will be improve...
