This paper studies the heat release rate of PVC desktop decoration materials, aiming to provide reference for fire prevention and control. PVC desktop decoration materials have beautifying and protecting functions, so they are widely used in daily life. However, fire accidents caused by these materials cannot be underestimated in recent years. When a fire accident happens, all kinds of decoration materials not only are supporters of combustion, but also release toxic gas in the process of combustion which is the main reason for casualties. Therefore, the heat release rates of PVC decoration materials with thicknesses of 1, 2 and 3 mm were measured based on the oxygen consumption principle using ISO 9705 standard small size heat release rate test bench. The test results show that the PVC decoration materials can be ignited by 2 mL n-heptane, and the maximum temperature reached more than 800℃. The maximum heat release rate of different samples increased with the increase of thickness, being 5.82, 4.41 and 2.83 kW/s. The total heat release rate took on an increasing trend. With the increase of sample thickness, the ignition time was prolonged, that is, the materials were more difficult to be ignited. A large amount of black smoke and pungent odors were released in the combustion process.
