Problems solved by technology

These fireproof materials themselves have certain safety hazards: (1) Good fire-resistant and flame-retardant effects are obtained by adding halogen flame retardants
Halogen flame retardants emit toxic hydrogen halide gas in a fire, which is harmful to human life. The hydrogen halide gas adheres to electrical equipment, which will cause corrosion damage to the equipment; (2) These fireproof materials have poor expansion in fire , the through-holes, especially the gaps of densely-packed cable-through holes, cannot be fully filled, and the size of the holes cannot be fully satisfied, resulting in the spread of flames, dense smoke and toxic gases; (4) The construction technology is backward, and it needs to be mixed and stirred at the construction site, which will pollute the environment, and may cause short circuit of live equipment during construction

Abstract

The invention relates to a high-expansion fireproof low-smoke halogen-free flame retardant composition and a thermoplastic resin composition. The high-expansion fireproof low-smoke halogen-free flame retardant composition contains 20-70 parts by mass of a component (A), 10-50 parts by mass of a component (B) and 15-60 parts by mass of a component (C), wherein the total amount of the components (A), (B) and (C) is 100 parts by mass. The component (A) is selected from one or two or more of piperazine polyphosphate, piperazine pyrophosphate, piperazine orthophosphate or piperazine diphosphate; the component (B) is selected from one or two or more of ammonium polyphosphate, melamine, melamine polyphosphate, melamine di-tripolyphosphate and melamine cyanurate; and the component (C) is expanded graphite. The high-expansion fireproof low-smoke halogen-free flame retardant composition disclosed by the invention has dual characteristics of flame retardance and fire prevention, and can quickly expand after catching fire at high temperature to form a compact expanded carbon layer, so that the effects of plugging, flame retardance, fire prevention, heat insulation, oxygen isolation and smoke suppression are realized.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a high-expansion, fire-proof, low-smoke, halogen-free flame retardant composition and a thermoplastic resin composition. Background technique [0002] The fire safety of materials used in densely populated areas plays a vital role in fire prevention. In the partitions between different areas in buildings and ship cabins, such as walls, bulkheads, ceilings, floors and other space division areas, it is necessary to set through holes and devices such as cables and pipes to realize water, electricity, gas, signals, etc. Transfer between different regions. However, the penetration hole will destroy the original fire protection system of the building, and the fire and smoke will spread rapidly between different areas through the pipeline penetration device, causing heavy losses. Especially in ships, penetration holes not only have to withstand high temperature an...
