Abstract
Against the background of people’s increasing awareness of personal safety and property safety, the flame retardancy (FR) of materials has increasingly become the focus of attention in the field of construction engineering. A variety of materials have been developed in research and production in this field. Polymers have many advantages, such as their light weight, low water absorption, high flexibility, good chemical corrosion resistance, high specific strength, high specific modulus and low thermal conductivity, and are often applied to the field of construction engineering. However, the FR of unmodified polymer is not ideal, and new methods to make it more flame retardant are needed to enhance the FR. This article primarily introduces the flame-retardant mechanism of fire retardancy. It summarizes the preparation of polymer flame-retardant materials by adding different flame-retardant agents, and the application and research progress related to polymer flame-retardant materials in construction engineering.

Summary
Fire accidents have occurred frequently, causing serious losses to people’s lives and of property. Enhancing the FR of polymers is a significant challenge in ensuring their safety and reliability in a wide range of applications [6,7]. Because of their light weight, low water absorption, high flexibility, good chemical corrosion resistance, high specific modulus and low thermal conductivity, polymers are often used in the field of construction engineering [8,9,10,11,12,13]. This paper mainly introduces the mechanism of flame retardancy, the classification of flame-retardant agents, the fabrication of flame-retardant polymer materials and their potential applications in the field of construction engineering
