Problems solved by technology

However, reactive flame retardants are mostly liquid, with average reactivity, and some monomers that do not participate in polymerization and curing are easier to precipitate from the composite material. The requirements for bubble process control are more stringent
[0004] Therefore, considering environmental protection, economy, ease of use, flame retardant efficiency and durability, etc., it is urgent to develop an applicable In polyurethane, it can solve the problem of poor compatibility and eliminate the influence of reactive flame retardants on the viscosity of the system.

Abstract

The invention discloses a zirconium phosphate-melamine cyanurate reactive flame retardant and a preparation method and application thereof. The invention utilizes the porous characteristics of zirconium phosphate and the swelling effect of the alcoholizing agent to enlarge the layer spacing of the zirconium phosphate, so as to provide space for the introduction of melamine cyanurate in the later stage. The urate composite material makes it surface active, can be well compatible with polyether polyol, and reacts with curing agent, so that zirconium phosphate-melamine cyanurate has the characteristics of reactive flame retardant, with phosphorus Nitrogen compounding theory ensures the flame retardant efficiency of composite flame retardants, significantly improves the compatibility of flame retardants in polyurethane, and then uses it in polyurethane composite materials to significantly reduce the amount of flame retardants added and improve The mechanical properties of the composite material are improved, so that the UL‑94 test of the composite material reaches V‑0 level, the oxygen index reaches more than 29%, and the compressive strength reaches 241Kpa.

Description

technical field [0001] The invention relates to the field of flame retardant material synthesis, in particular to a zirconium phosphate-melamine cyanurate reactive flame retardant and its preparation method and application. Background technique [0002] Polyurethane is generally obtained by the interaction of dibasic or polybasic organic isocyanate and polyol compound (polyether or polyester polyol). Polyurethane foam, known as the "fifth largest plastic", has excellent physical, mechanical, acoustic, electrical and chemical resistance properties, and is widely used in construction, transportation, interior decoration and other fields. However, due to its own molecular structure characteristics, it is extremely It is easy to burn, which greatly limits the application prospects of polyurethane. [0003] At present, flame retardants for polyurethane are mainly divided into additive type and liquid reactive type. Among them, the method of adding flame retardant has the advanta...
