Abstract

The invention belongs to the technical field of expanded plastic, and particularly relates to halogen-free flame-retardant polyurethane expanded plastic. The plastic is prepared from the following raw materials in percentage by weight: 40-80% of water, 10-20% of 1, 4-hexamethylene diisocyanate, 5-35% of polyethylene glycol adipate glycol, 2-5% of a chain extender 1, 4-butanediol, 1-5% of a halogen-free flame retardant, 0.001-0.1% of a catalyst, 0.1-1% of a foam stabilizer and 0.2-0.8% of an antioxidant. Compared with the prior art, the halogen-free flame-retardant polyurethane expanded plastic has the advantages that water is adopted as the foaming agent, so that damage caused by a fluorine-containing foaming agent such as HCFC-141b (1,1-dichloro-1-fluoroethane) to the environment is effectively avoided; the halogen-free flame retardant is added, so that the flame-retardant performance of the TPU (thermoplastic polyurethane) expanded plastic is improved; the flame retardant used does not contain halogens or heavy metal elements such as lead, cadmium, mercury, chromium and the like, so that the plastic satisfies the demand of European Union VDE (Verband Deutscher Elektrotechniker) and is a green and environment-friendly material.

Description

technical field [0001] The invention belongs to the technical field of foamed plastics, in particular to a halogen-free flame-retardant polyurethane foamed plastic. Background technique [0002] TPU (thermoplastic polyurethane) is an environmentally friendly polymer. It overcomes many defects of PVC and PU leather. It not only has most of the characteristics of rubber and ordinary plastics, but also has excellent comprehensive physical and chemical properties, so it is also called TPU. Future material. It is a mature environmentally friendly material, which has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance and weather resistance that other plastics and natural materials cannot match. Waterproof, moisture permeability, windproof, coldproof, antibacterial, mildewproof, warm, anti-ultraviolet and energy release and many other excellent functions. [0003] After TPU is foamed, it can b...
