Problems solved by technology

Red phosphorus and ammonium polyphosphate are common components of phosphorus-based flame retardants and nitrogen-phosphorus composite intumescent flame retardants. Due to the high phosphorus content, the flame retardant effect is good and the flame retardant efficiency is also high. Ammonium polyphosphate als

Abstract

The invention discloses a fire retardant, belonging to the field of fire-proof technology. The fire retardant comprises the components by weight percent: 45-55% of epoxy resin coated ammonium polyphosphate, 10-15% of pentaerythritol, 3-5% of melamine, 5-10% of coated red phosphorus, 5-10% of magnesium hydroxide, 5-10% of aluminium hydroxide, 5-10% of zinc borate, 1-5% of carbon formation accelerator, 1-5% of smoke suppression agent and 0.5-3% of coupling reagent. The fire retardant is capable of inhibiting flame combustion and smoldering, can be smeared or sprayed onto any object so as to guarantee the object to be only carbonized without burning, has good compatibility with material, can be evenly dispersed on the material which is prevented from burning, and has better affinity; the fire retardant is high in stability, so that the physical and technical performances of the material mixed with the fire retardant are not influenced; and the fire retardant causes less smoke during burning and does not generate poisonous gas, thus belonging to environment-friendly fire retardant and being added into materials such as plastics, paint, and rubber.

Description

technical field [0001] The invention relates to the field of flame retardant technology, in particular to a flame retardant. Background technique [0002] At present, the polymer material industry is developing rapidly and its application fields are constantly expanding. However, it has the characteristics of flammability. In fields with high safety requirements, such as chemical building materials, electronic appliances, transportation, aerospace, daily furniture, interior decoration And other fields, the application of flame retardant polymer materials is increasing. [0003] Flame retardants added to polymer materials are mainly divided into halogen-based flame retardants, phosphorus-based flame retardants, nitrogen-phosphorus composite intumescent flame retardants, and inorganic flame retardants. Red phosphorus and ammonium polyphosphate are common components of phosphorus-based flame retardants and nitrogen-phosphorus composite intumescent flame retardants. Due to the ...
