Abstract

The invention discloses an environment-friendly polyurethane track material formula, which is mainly characterized in that low-toxicity harmless chain expanding agents of 4,4'-methylene-bis(3-chloro-2,6-diethylaniline) (M-CDEA) and 4,4'-di-sec-butyl aminodiphenylmethane are used; the environment-friendly performance of the track material is improved. The formula uses a semi-prepolymer method for synthesizing a solvent-free polyurethane track material, wherein an ingredient A is prepared by the steps of taking a certain amount of polyether glycol; adding the polyether glycol into a reaction kettle; performing stirring for temperature rise to 110 to 120 DEG C; performing dewatering for 2 h; lowering the temperature to 40 to 60 DEG C; adding a certain amount of isocyanate; performing stirringand temperature rise to 80 to 90 DEG C; performing constant temperature reaction for 2 h; lowering the temperature; performing discharging. An ingredient B is prepared by the steps of performing stirring and temperature rise on polyether glycol, chain expanding agents and plasticizers to 110 to 120 DEG C; performing dewatering for 2 h; then, lowering the temperature to the room temperature; adding filling materials; performing uniform mixing; performing discharging. The ingredient A and the ingredient B are mixed according to a certain mass ratio; the catalyst is added; the material is uniformly stirred. The double-ingredient polyurethane track material has the advantages of non-toxicity, environment-friendly effect and good mechanical performance.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an environment-friendly polyurethane track material formula. Background technique [0002] Polyurethane is a general term for macromolecular compounds containing repeated urethane groups on the main chain, which is polymerized from oligomer polyols and isocyanates. The plastic runway paved with polyurethane has the advantages of good elasticity, strong wear resistance, good skid resistance, stable physical properties and can be used all-weather. With the rapid development of polyurethane runway materials, its environmental performance has also received widespread attention. Especially with the emergence of the "poisonous runway" incident, people's demand for environmentally friendly polyurethane runway materials has further increased. However, most of the chain extenders used in the synthesis of traditional polyurethane track materials are 3,3'-dichloro-4,4'-diphenylmethanediam...
