Abstract

The invention discloses a molybdenum trioxide microsphere flame-retardant smoke-suppressing polypropylene composite material and a preparation method thereof, and relates to the technical field of polymer materials. The molybdenum trioxide microsphere flame-retardant smoke-suppressing polypropylene composite material is prepared from the following raw materials: polypropylene resin, molybdenum trioxide microspheres, mineral powder, a toughening agent, an antioxidant, a light stabilizer and a lubricant. The preparation method has the characteristics that firstly the molybdenum trioxide microspheres are synthesized by using a hydrothermal method, and the molybdenum trioxide microspheres are uniformly distributed and have good dispersibility in a polypropylene matrix, and have little influence on mechanical properties of the material; and a larger specific surface area of the molybdenum trioxide microspheres is utilized, so that char formation of the polypropylene and absorption of smokegenerated by the material when the material is thermally decomposed can be more effectively promoted, and a low smoke density flame-retardant polypropylene composite material is obtained. The synthetic raw materials of the molybdenum trioxide microspheres are easy to purchase, and the molybdenum trioxide microspheres are economical, environmentally friendly, and efficient, so that the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant and smoke-suppressing polypropylene composite material of molybdenum trioxide microspheres and a preparation method thereof. Background technique [0002] When a fire breaks out, the smoke is also very harmful. They have a strong stimulating effect on the nose, eyes, and throat of people, causing difficulty in breathing, and affecting the sight of personnel when escaping and firefighters rescue. Many fires can prove that smoke It is also the main factor causing casualties. [0003] Liu Xiu et al. added molybdenum trioxide to polyurethane foam, and studied the effects of different additions of molybdenum trioxide on the flame retardancy and smoke suppression performance of PUF. The results showed that adding 5% MoO 3 That is to say, the maximum smoke density of flame-retardant PUF is reduced by 22%, and the charcoal residue burned is increased from 8% ...
