Problems solved by technology

Although the composition can improve the stability of the polymer to light and avoid the deterioration of the polymer (such as embrittlement, yellowing or aging, etc.), the effect still does not meet the needs of the industry

Abstract

An assistant composition used for a polymer includes a triazine light absorbent, a component containing a polyisocyanate group, and a hindered amine component containing a reaction function group, and the reaction function group comprises at least one of a hydroxyl group, a mercapto group and an amino group. The assistant composition used for the polymer is added to the polymer in order to form a composite material having good light stability and being difficult to deteriorate.

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 ...
