4results about How to "Improve bonded state" patented technology

Provided are a heat-sealable laminated film which has a high adhesion force at a laminated interface and has a good bonded state when being heat-sealed, and a roll obtained by rolling the heat-sealable laminated film. A heat-sealable laminated film includes a layer B, a layer C, a layer A, a layer C, and a layer B in this order. At least the layer C, the layer A, and the layer C are laminated by co-extrusion. The layer A contains 100 to 70% by mass of a polymer A1 containing 90 mol% or more and 100 mol% or less of a constitutional unit derived from 4-methyl-1-pentene with respect to all constitutional units. The layer B contains 100 to 70% by mass of a heat-sealable polyolefin B1. The layer C contains 50% by mass or more of a copolymer C1 containing 60 mol% or more and 99 mol% or less of a constitutional unit derived from 4-methyl-1-pentene and 1 mol% or more and 40 mol% or less of a constitutional unit derived from an α-olefin having 2 or more and 20 or less carbon atoms other than 4-methyl-1-pentene.

This invention provides a high-wear-resistant polyamide composite material and its preparation method. The modified carbon nanotubes of this invention, due to their nanoscale structural characteristics, can effectively exert a nano-reinforcing effect, improving the mechanical strength and anti-slip and wear-resistant properties of the polyamide composite material. On one hand, the fluoroalkyl chains grafted onto their surface improve compatibility with polytetrafluoroethylene (PTFE), while the amide groups from N,N'-methylenebisacrylamide enhance the interfacial bonding between the carbon nanotubes and the nylon matrix, effectively preventing filler agglomeration and precipitation. On the other hand, the hydroxyl groups can interact with the carboxyl groups of the nylon matrix, enhancing the material's mechanical properties and anti-slip and wear-resistant properties. Furthermore, the good interfacial compatibility of the modified carbon nanotubes improves the bonding state between PTFE and the nylon matrix, enhancing material performance. Additionally, this invention modifies glass fibers with polyethyleneimine, which facilitates their interaction with other components, further improving material performance.
