Waterborne flame retardant adhesive and preparation method thereof
Technical Field The invention relates to a heat insulating material is used for outsourcing aqueous flame-retardant adhesive and its preparation method, in particular relates to a water-based fire-retardant adhesive and method for preparing same. Background Art Adhesive series flame retardant adhesive glue is relatively special products in the product, is mainly applied to the paper, polyester film, the surface of the packaging material, fire-retardant material such as asbestos sandwiched in the middle, then the thin film material of the composite, the composite product is mainly used for heat-insulating material, and the like outside the installation, is the more popular mode of construction of the heat insulating material. Generally, the flame-retardant polymer compared with flame retardant similar material, have a high thermal stability, low burning rate, and it is difficult to ignite. Under the high temperature, however, still produce but however nature gas, when the condition is sufficient, can still be burning. Some flame-retardant material is very difficult to ignite, and some other fire-retardant material may in some test condition can be relatively easy to be ignited, such as expansion of the material of the flame-retardant system, after being ignited, combustion for a while, when a foam layer when coal is self-extinguishing, flame retardant so as to achieve the purpose. The flame-retardant adhesive in great demand, research in this area is still very small. Adhesive is a high molecular compound, meet the general conditions for combustion of high, if not through the flame retardant treatment, it is impossible to use the field of flame retardant requirements. The flame-retardant adhesive on the market now are most of the main raw materials for producing oily substance, not only high cost of raw materials, it is difficult to separate and contain a lot of harmful chemical substance to the human body, such as benzene. As human health requirements increase, the use of such glue become increasingly constrained range, range become increasingly smaller. Because the market demand and the current of the flame-retardant glue itself clear contradiction defect exist, heat-insulating fireproof industry many of the manufacturers can only in the restricted product uses other types of adhesive to replace. Therefore, aqueous flame-retardant adhesive on the market have very large development space.
