Problems solved by technology

[0002] After all kinds of plastics are recycled, sorted, crushed, and re-granulated, they can be directly mixed with new materials for use under normal circumstances. In other cases, the performance of products mixed with recycled plastics will decrease in different proportions, reducing the use value of products. Therefore, in the recycling and use of plastics, the recycling ratio is limited.

Abstract

The inorganic nanometer particle modified high performance regenerated plastic consists of recovered plastic 5-98 wt%, new plastic in the same type 0-93 wt%, inorganic nanometer particle 1-30 wt%, flexibilizer and compatilizer 1-30 wt%, and alkali free glass fiber 0-45 wt%, and the surface of the alkali free glass fiber is treated with silane coupler in the amount of 0.2- 5% of the added alkali free glass fiber. The said components are mixed homogeneously through stirring, melted and extruded to form.

Description

technical field [0001] The invention discloses a nano-modified recycled plastic and a preparation process of the nano-modified recycled plastic, belonging to the technical field of composite materials. Background technique [0002] After all kinds of plastics are recycled, sorted, broken, and re-granulated, they can be directly mixed with new materials for use under normal circumstances. In other cases, the performance of products mixed with recycled plastics will decrease in different proportions, reducing the use value of products. Therefore, in the recycling and use of plastics, the recycling ratio is limited. [0003] In order to solve these problems, people at home and abroad have been conducting related research. CN93117398.1 reports that special stabilizers are added to recycled plastics to prevent the degradation of plastics; The properties of plastics are improved. Contents of the invention [0004] The purpose of the present invention is to overcome the deficie...
