To described pre-dispersed masterbatch particles.
Preferably, in the step (1) of the method, it is additionally added 2-((S)-6-(((S)-4-(4-(3-first
Epoxide propoxyl group)-2,6-3,5-dimethylphenyl)-2,3-dihydro-1H-indenes-1-base) epoxide)-2,3-dihydrobenzene
And [b] thiene-3-yl) acetic acid.
The present invention also provides for 2-((S)-6-(((S)-4-(4-(3-methoxy propoxy)-2,6-dimethyl benzene
Base)-2,3-dihydro-1H-indenes-1-base) epoxide)-2,3-dihydrobenzo [b] thiene-3-yl) acetic acid is being used as
Purposes in antibacterial.
The present invention is by optimizing formula and the preparation work of pre-dispersed masterbatch particles of pre-dispersed masterbatch particles
Skill, compared with prior art, has the advantages that
1, add TDEC and DPTT double-component active component, possess collaborative facilitation, pole
Improve greatly the curingprocess rate of rubber, and effectively improve the mechanical property of vulcanite and aging
Performance.
2, add double-component surfactant processing aid, improve the dispersibility of active component,
Have good interior lubricant effect and outer lubricant effect concurrently.
3, the combination of ultra-fine filling material, especially Kaolin and Pulvis Talci ultra-fine filling material is added, greatly
Improve the mechanical property of rubber and the viscosity flow in mixing process can be effectively improved.
4, by the present invention improvement to pre-dispersed masterbatch particles preparation technology, active component can
It is evenly distributed in rubber carrier, has reached preferable discharging effect, and masterbatch particles discharging is equal
Even, particle surface smooths, and possesses good processing characteristics.
Detailed description of the invention
Below by way of the description of detailed description of the invention, the invention will be further described, but this is not
