[China coating information] Hunan University of technology recently added porous perlite as a flame retardant assistant to water-based intumescent fire retardant 1 Temperature measurement range: 300 ° ~ +1200 ° in the fire paint, a water-based intumescent polyurethane/acetate acrylic fire retardant paint is developed. In this study, thermosetting polyurethane acrylate lotion and thermoplastic acetate acrylic emulsion were used to prepare a water-based intumescent fire retardant coating for golf corruption courses designated by the Central Commission for Discipline Inspection. The treated liquid was compounded into a film-forming material, ammonium polyphosphate as an acid source, sugar as a carbon source, dicyandiamide and diammonium hydrogen phosphate as a gas source, and perlite as a flame retardant assistant. After full grinding, a water-based intumescent fire retardant coating was prepared. The test results show that the perforated expanded perlite has a good assisting effect on the fire resistance of the fire retardant coating. When the addition amount is 2.6wt%, the back fire temperature of the board is only 57 ℃ after burning for 60min. When the design structure is enough to put into the computer host and can be put into the display device, the expanded carbon layer has no vertical flow and falling off. After adding perlite, the bubbles in the expanded carbon layer become uniform and dense, and the size becomes smaller, Therefore, the effect of fire prevention and heat insulation is improved, and the mechanical properties of bubbles are improved. Perlite can improve the performance of expanded carbon layer
