Abstract

The invention discloses a binding resin for multilayer coextruded hoses. The binding resin comprises the following raw materials in parts by weight: 15-50 parts of HDPE (high-density polyethylene), 40-80 parts of EEA, 1-20 parts of polyethylene wax, 0.1-30 parts of talcum powder and 0.1-7 parts of hindered phenolic antioxidant. The binding resin disclosed by the invention has favorable compatibility between the barrier layer and substrate, and thus, widens the selection range of the hose material; and the binding resin has high binding force, and thus, the hose has more excellent overall barrier property.

Description

technical field [0001] The invention relates to a bonding resin, in particular to a bonding resin for multi-layer co-extruded hoses. Background technique [0002] In the past ten years, cosmetic hose materials have become the fastest-growing field in China's packaging industry, and will continue to grow at an annual rate of 11-12%. The cosmetic hose industry has a very large market potential in China. It has Its light weight, high softness, bright colors, high performance, low cost, reduced waste and improved space utilization make it replace traditional packaging materials in many applications. The adhesive resin connecting the base material and the heat-sealing layer in the composite packaging material plays a key role. It not only needs to play the role of high barrier properties of the functional layer, but also needs to play a good role as an adhesive. There are many types of bonding resins in the prior art. In the prior art, polyurethane adhesives are generally used t...
