Abstract

The invention discloses a kind of blending of high intensity NR, EVA to be formulated, by 20~25 parts of NR natural rubbers, 68~72 parts of EVA resins, 16~19 parts of CaCO3, 2.2~2.5 parts of DOP, 1.1~1.4 parts of DCP, 3.6~3.9 parts of H foaming agents, 4.1~4.3 parts of ZnO blowing promotors, 1.1~1.4 parts of ZnSt blendings form.The present invention significantly improves intensity.

Description

High intensity NR, EVA blending formula
Technical field
The present invention relates to a kind of polymer composite formula, particularly a kind of NR, EVA blending formula.
Background technology
NR, EVA intermingling material have higher elasticity, but intensity is relatively low.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes that a kind of high intensity NR, EVA blending that can significantly improve intensity is matched somebody with somebody Side.
The present invention is achieved through the following technical solutions technical goal.
High intensity NR, EVA blending formula, it is theed improvement is that：By 20~25 parts of NR natural rubbers, 68~72 parts of EVA Resin, 16~19 parts of CaCO3, 2.2~2.5 parts of DOP, 1.1~1.4 parts of DCP, 3.6~3.9 parts of H foaming agents, 4.1~4.3 parts ZnO blowing promotors, 1.1~1.4 parts of ZnSt blendings form.
Further improvement is that：By 22~24 parts of NR natural rubbers, 70~71 parts of EVA resins, 17~18 parts of CaCO3、2.3 ~2.4 parts of DOP, 1.2~1.3 parts of DCP, 3.7~3.8 parts of H foaming agents, 4.2~4.25 parts of ZnO blowing promotors, 1.2~1.3 parts ZnSt blendings form.
The present invention compared with prior art, has the positive effect that：
1st, NR, EVA are blended, and add CaCO3, significantly improve intensity.
2nd, by 22~24 parts of NR natural rubbers, 70~71 parts of EVA resins, 17~18 parts of CaCO3, 2.3~2.4 parts of DOP, 1.2~1.3 parts of DCP, 3.7~3.8 parts of H foaming agents, 4.2~4.25 parts of ZnO blowing promotors, 1.2~1.3 parts of ZnSt blending and Into can further improve intensity.
