Description

technical field

[0001] The invention relates to an auxiliary agent composition, in particular to an auxiliary agent composition for polymers. Background technique

[0002] Among polymer materials, polyolefin has become a widely used polymer material because of its better chemical resistance and mechanical properties. However, polyolefins are easily affected by light during processing or use of finished products made of polyolefins, resulting in deterioration problems such as yellowing, aging, or embrittlement.

[0003] US Patent Publication No. 6051164 discloses a composition for protecting polymers from ultraviolet light. The composition includes ortho-hydroxy tris-aryltriazine light absorber (ortho hydroxy tris-aryltriazine light absorber) and hindered amine light stabilizer (hindered amine light stabilizers, HALS) with molecular weight above 500. The weight ratio of the hindered amine light stabilizer to the o-hydroxyl-triaryl triazine light absorber ranges from 3:1 to ...
