Abstract

The invention belongs to the technical field of flame retardants and particularly discloses a flame retardant for a polyvinyl chloride wall decoration film material. The flame retardant is prepared from the following raw materials: a bismuth compound, an adsorbent, an inorganic mineral flame retardant, a fungicide, an antioxidant and calcium stearate. The invention further discloses a preparation method of the flame retardant. The method comprises the steps of firstly preparing the fungicide; grinding the absorbent into absorbent particles; treating the surfaces of the bismuth compound and the inorganic mineral flame retardant by adopting a silane coupling agent; and finally feeding the fungicide, the absorbent particles, a silane coupling agent-modified bismuth compound and a silane coupling agent-modified inorganic mineral flame retardant into a high-speed mixer, adding the antioxidant and the calcium stearate and mixing for 15min. The flame retardant for the polyvinyl chloride wall decoration film material is free of halogen, free of stibium, free of phosphate and free of boron and is an environment-friendly nonvolatile high-performance flame retardant.

Description

technical field [0001] The invention relates to the technical field of flame retardants, in particular to a flame retardant for polyvinyl chloride wall decoration film material and a preparation method thereof. Background technique [0002] PVC is polyvinyl chloride. It has good environmental protection, aging resistance and ductility. The surface of the film material is smooth, non-toxic and water-resistant. It is an ideal material for indoor wall decoration. With the development of social economy, people have higher and higher requirements for living environment, including visual sense, sense of smell, and safety of healthy living environment. Polyvinyl chloride is a high-performance material that is friendly to the human body and environmentally friendly. It has good flame retardancy and is widely used in daily life. It is a polymer material that is difficult to give up. In commonly used PVC materials, in order to obtain other physical properties, plasticizers are often ...
