Abstract

The invention discloses an antiaging polyurethane composite material which is prepared from polyoxypropylene diol, hydroxyl-terminated liquid silicone rubber, hydroxyl-terminated liquid nitrile-butadiene rubber, 1,4-cyclohexane diisocyanate, 1,5-naphthalene diisocyanate, 1,4-butynediol, 1,4-di(2-hydroxyethoxy)benzene, 4,4'-diaminodiphenyl sulfone, dibutyltin dilaurate, bis dodecyldimethyl ammonium bromide, graphene oxide, carbon nanotubes, hydroxy polydimethylsiloxane, a heat stabilizer, polystyrene and a rare-earth complex. The heat stabilizer is prepared from nano titanium dioxide, molybdenum trioxide, bismuth trioxide, triglycol bis-[3-(3-tert-butyl-4-hydroxy-5-methylphenyl)propionate], pentaerythritol diisodecyl diphosphite, monophenyldiisodecyl phosphite and ethyl 2,2'-thiobis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate].

Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to an aging-resistant polyurethane composite material. Background technique [0002] Polyurethane is formed by addition polymerization of diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compound. In addition to carbamate, the macromolecule also contains ether, ester, urea, biuret, allophanate and other groups. There are many structural changes, and it has been widely used in many aspects. For example, it can replace rubber, plastic, nylon, etc., and is used in airports, hotels, building materials, automobile factories, coal mines, cement factories, high-end apartments, villas, landscaping, color Stone art, parks and other fields. However, the weather resistance of polyurethane is poor, and it is prone to aging phenomena such as yellowing and cracking when used outdoors, which seriously affects the appearance and mechanical properties of the product.
