Abstract

The invention discloses a high-tenacity PA and EPDM blend formula. According to the high-tenacity PA and EPDM blend formula, by part, every 100 parts of PA-66 resin is prepared with 19-23 parts of sulfonated EPDM and 4.5-5.5 parts of ZnSt. The high-tenacity PA and EPDM blend formula can significantly improve the tenacity.

Description

technical field [0001] The invention relates to a polymer composite material formulation, in particular to a PA blending formulation. Background technique [0002] The strength and toughness of PA blended materials are high, but the toughness still needs to be improved if it is used to make automobile bumpers. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a high-toughness PA and EPDM blending formula that can significantly improve the toughness. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The improvement of the high-toughness PA and EPDM blend formula is: 19-23 parts of sulfonated EPDM and 4.5-5.5 parts of ZnSt are prepared in every 100 parts of PA-66 resin. [0006] The further improvement is that: 21-22 parts of sulfonated EPDM and 4.8-5.2 parts of ZnSt are prepared in every 100 parts of PA-66 resin. [0007] Compared with the prior art, the present...
