Embodiment Construction

[0022] An environmentally friendly low-smoke expansion type flame retardant, which is made from the following raw materials by weight (kg): bromotriazine 15, antimony trioxide 3, ammonium polyphosphate 35, melamine 20, polypentethritol 15 , Urate 8, Magnesium Hydroxide 2, Ionic Surfactant 0.3.

[0023] The preparation method of the environment-friendly low-smoke expansion flame retardant comprises the following steps:

[0024] Add ammonium polyphosphate, melamine, polypentylthritol, and urate into the reactor in parts by weight, and control the temperature of the reactor to rise slowly at 10°C / min by controlling the speed of the mixer in the reactor, and keep it at 100°C for 20 minutes. Slowly add bromotriazine, antimony trioxide, and magnesium hydroxide, slowly add ionic surfactant after 10 minutes, stop the reaction in 15 minutes, and discharge the product.

[0025] Taking the flame retardant in this example as the raw material to prepare the copolymerized PP as an example,...

Abstract

The invention discloses an environmentally-friendly low smoke intumescent flame retardant and a preparation method thereof. The flame retardant is prepared from, by weight, 8-15 parts of brominated triazine, 1-6 parts of antimony trioxide, 30-35 parts of ammonium polyphosphate, 15-20 parts of melamine, 12-15 parts of polypentaerythritol, 7-9 parts of urate, 2-5 parts of an inorganic additive and 0.1-3 parts of an ionic surfactant. The flame retardant is produced by special formula compounding and a special technology, has a substantial flame retardation effect, is a white (crystalline or amorphous) powder, is a mixture, and has a flame retardation effect on polyolefin through the coordination effect of substances. The flame retardant has the advantages of good flame retardation effect, high thermal stability, realization of the decomposition temperature being greater than 280 DEG C, high residual carbon rate, small moisture absorption, excellent dispersion, good chemical stability, and realization of mixing with other substances without chemical reactions.

Description

technical field [0001] The invention relates to the field of flame retardants, in particular to an environment-friendly low-smoke expansion type flame retardant and a preparation method thereof. Background technique [0002] Polymer materials are widely used in various fields of national economy and people's life because of their excellent performance and low price. In 2000, the production volume of plastic alone reached 170 million tons, and its volume was much larger than that of steel produced in the same year. However, most polymers are flammable and combustible materials. When burning, the heat release rate is high, the calorific value is high, the flame spreads fast, and it is not easy to extinguish. Sometimes it also produces thick smoke and toxic gases, causing harm to the environment and people. For example, fires have occurred frequently in recent years, and accidents of serious fire injuries have often occurred, especially several fires in public places have cause...
