Problems solved by technology

[0003] The critical surface tension of PP is small, the inertia is strong, the affinity with ink is poor, and the adhesion fastness to ink is relatively low, so the printing performance of PP is poor
limit its scope of application

Abstract

The invention relates to a POE graft polymer for enhancing PP printing performance. The POE graft polymer comprises 8-10 parts by weight of 7-amino-3-vinyl-8-oxo-5-thia-1-azabicyclo(4,2,0)oct-2-ene-2-carboxylic acid, 0.30-0.50 part by weight of 2,5-dimethyl-2,5-bis(tert-butyl peroxy)hexane, 0.20-0.30 part by weight of dioctyl tin dilaurate, 0.20-0.25 part by weight of an antioxidant 1010, 0.30-0.35 part by weight of an antioxidant DLTP and 0.8-1.0 part by weight of a wetting agent EBS, wherein the total part by weight of the components is 100. By the adoption of the method, the surface wettingtension is remarkably improved, good printing performance is shown, and the low-temperature impact strength and the antistatic performance are also greatly improved; and the PP polymer has excellentprinting performance and good comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a POE graft polymer for enhancing the printing performance of PP and a preparation process thereof. Background technique [0002] Polypropylene (PP) is a thermoplastic polymer. With good physical and mechanical properties, it is widely used in daily necessities, machinery, electronic appliances, household appliances, product packaging, plates, etc. PP has high crystallinity and low surface tension. It is a polymer material with a non-polar molecular structure. [0003] PP has low critical surface tension, strong inertness, poor affinity with ink, and relatively low adhesion fastness to ink, so PP printing performance is poor. limited its scope of application. Contents of the invention [0004] The invention provides a POE graft polymer for enhancing the printing performance of PP and its preparation process, which is used to improve the disadvantage of poor printing performa...
