Abstract

The invention discloses a red phosphorus master batch flame retardation PTT polyester and a preparation method therefor. The red phosphorus master batch flame retardation PTT polyester comprises the following ingredients, by weight, 60%-80% of PTT, 10%-15% of red phosphorus master batch, 8%-15% of glass fibers, 2%-8% of POE, 1%-4% of calcium oxide, 0.1%-0.5% of aluminum titanium composite coupling agents, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The calcium oxide is calcium oxide particles with a particle size of being less than 5 micrometers. The beneficial effects are that the red phosphorus master batch is employed as a flame retardant, the flame retardation of PTT is raised, and the tensile strength, the bending strength and the CTI value of PTT are also raised obviously; a proper amount of calcium oxide is added for strengthening, a proper amount of POE is added for toughening, calcium oxide and the red phosphorus master batch has good flame retardant synergism effects, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a red phosphorus masterbatch flame-retardant PTT polyester and a preparation method thereof. Background technique [0002] Polytrimethylene terephthalate (PTT) is an aromatic polyester synthesized by esterification and polycondensation of terephthalic acid and 1,3-propanediol. Since its industrial production in the 1990s, it has been widely used in Fiber, film, engineering plastics and other fields. Especially in the field of engineering plastics, PTT has both the high performance of PET and the ease of processing of PBT, and its price is much lower than that of PBT, so it has important application value. However, PTT itself cannot be flame-retardant (the limiting oxygen index is about 21), which limits the application range of PTT. Contents of the invention [0003] The object of the present invention is to provide a kind of red phosphorus masterbatch flame-retarda...
