Abstract

The invention relates to a novel high-performance environment-friendly adhesive and a preparation method thereof, which is characterized in that the adhesive contains the following raw material components in percentage by weight: polyolefin graft adhesive resin 30-60%, polyester elastic Body 10‑30%, tackifying resin 10‑20%, modifier 5‑10%, polymerization inhibitor 0.4‑3%, viscosity regulator 3‑5%, antioxidant 0.2‑1%, auxiliary agent 0.4‑ 3%; this new type of high-performance environmentally friendly adhesive is developed based on the shortcomings of the current commercial 3PE adhesives. It uses new grafting reaction equipment, improves the initiator and grafting monomer, increases the depth of grafting reaction, and optimizes the molecular chain structure of the product. Enhance the bonding strength, reduce the thickness of the adhesive layer by 10-20μm, and the thickness of the adhesive layer is 150-230μm, which saves application costs and has obvious technical advantages.

Description

technical field [0001] The invention relates to an adhesive, in particular to a high-performance environment-friendly adhesive and a preparation method thereof, belonging to the field of polymer composite material preparation and processing. Background technique [0002] Metal corrosion is a major economic problem. The outer anti-corrosion layer of oil and gas pipelines is an important barrier to ensure the safety of pipelines. The anti-corrosion technology of pipelines and components plays an important role in the overall structure of the national economy, which is related to the use of oil and gas transmission and other fields. Safety and facility life issues. At present, the economic damage caused by metal corrosion is huge every year, especially for the external anti-corrosion technology of pipelines, which also puts forward higher requirements. After years of development and evolution, anti-corrosion coatings have formed a variety of patterns, including 2 / 3PE anti-corr...
