Abstract

The invention discloses a high-density polyethylene composition and a preparation method thereof. The high-density polyethylene composition comprises the following components in parts by weight: 100 parts of high-density polyethylene; 13.5 to 17.5 parts of a main flame retardant; 3.5 to 7.5 parts of an auxiliary flame retardant; 3-6 parts of a toughening agent; 2-6 parts of a main antioxidant; 2-4parts of an auxiliary antioxidant; 3-6 parts of a dispersant; 1-4 parts of an auxiliary flame retardant; 2-4 parts of a toughening oil. The high-density polyethylene composition is excellent in flameretardant property, the flame retardant property meets the B1 level flame retardant requirement (according to GB / T27904-2011 Testing method for fire characteristics of furniture and subassemblies exposed to flaming ignition source), toughening and environment pressure cracking resistance are achieved, the European Union RoHS instruction standard is met, and the high-density polyethylene composition is particularly suitable for the field of seats. The seats prepared from the composition is successfully applied to many stadiums.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-density polyethylene composition and a preparation method thereof. Background technique [0002] High-density polyethylene (HDPE) is one of the five most important general-purpose plastics. It is widely used because of its excellent comprehensive performance, abundant raw material sources, and low cost. However, HDPE resin is flammable and has a low oxygen index (17.5), so its flame retardancy must be improved before it can be fully used. Flame retardants are usually added to improve flame retardancy. Flame retardants are mainly divided into halogen-based, inorganic-based and phosphorus-oxygen-based. Although the current development direction of flame retardants is the trend of adopting new varieties with low toxicity, low smoke and high heat resistance, non-halogen, halogen-based flame retardants have the characteristics of low cost, less addition, and many va...
