Abstract

The invention discloses a modified amino foam insulation board. The modified amino foam insulation board is prepared from modified urea resin, lauryl sodium sulfate, phosphoric acid, urea, polyvinyl alcohol, glycerol, polyoxyethylene, ammonium chloride, inorganic fibers and graphite powder. The preparation method comprises the steps of foaming solution preparing, foaming, secondary composite foaming, drying and trimming and cutting. The preparation technology is simple, and the production cost is low; the insulation board has the advantages that thermal insulation and fire prevention are achieved, no toxin or odor exists, the environment cannot be polluted, and the sound insulation performance is good.

Description

technical field [0001] The invention designs a thermal insulation board and a preparation method thereof, in particular a modified amino foam thermal insulation board and a preparation method thereof. Background technique [0002] In the prior art, the thermal insulation materials for the external walls of buildings are generally pure organic materials. Although the thermal insulation effect has reached the relevant national standards, the fire performance level is relatively low and fires are prone to occur. The analysis of some high-rise building fire cases at home and abroad shows that the main characteristics of high-rise building fires are strong chimney effect, serious smoke hazards, and rapid flame spread, which can easily form a situation of simultaneous burning of several layers, forming a three-dimensional fire, which directly threatens People's lives are safe. Contents of the invention [0003] In order to solve the above problems, the invention provides a modi...
