AI Technical Summary
Existing outdoor rattan and artificial turf polyolefin products are prone to fading and becoming brittle under long-term ultraviolet radiation. In existing anti-UV systems, additives are prone to migration and loss, and pigments are not well matched with the anti-UV system, which cannot meet the requirements of long-term colorfastness and non-brittleness.
A composite UV stabilizer using a specific mass ratio of high molecular weight hindered amine light stabilizer, modified hindered amine light stabilizer, and benzotriazole UV absorber is formed by graft copolymerization, which links the modified hindered amine light stabilizer to the polyolefin chain through chemical bonds, forming a uniformly distributed UV stabilizer network. Combined with a reasonable ratio of carrier resin, pigment, and dispersing lubricant, the compatibility and migration resistance are improved.
It achieves high weather resistance outdoor rattan and artificial turf fiber UV-resistant masterbatch that does not fade or become brittle under long-term sun and rain conditions, maintains excellent UV resistance and high mechanical properties, tensile strength retention rate ≥87.1%, no exudation, no blooming, no powdering on the surface, and strong migration resistance.
