Abstract
The invention relates to an atactic block polyamide material, which comprises the following components by weight portion: 200 to 950 portions of polyamide, and 50 to 800 portions of polycaprolactone. Compared with the prior art, the material can effectively improve mechanical property and other properties of the polyamide, and widen the application range of the polyamide.
Description
Technical field
The present invention relates to polyamide material, relate in particular to a kind of random block polyamide material.
Background technology
In view of development, material is had higher requirement to the demand of daily necessities.Make high-strengthly, strong, sense organ is good, and the novel material that machine-shaping is easy is our current urgent task.This depends on the one hand existing macromolecular material is carried out blend or filling-modified, depends on the development of polymer kind on the other hand, to improve its every physical and mechanical properties index.Blend and fill method are often sacrificed the performance of a lot of excellences to reduce cost, and cause original just a large amount of wastes of Chemicals very in short supply.
Polymeric amide is commonly called as nylon, is the thermoplastics that a class has excellent physical and mechanical properties, has a large amount in variety on the market, and relative merits are different.Because its structure and biological intravital seemingly protein-based has better biocompatibility, is widely used in medical material. if can make its processing conditions gentle, biodegradable more, then can expand their application space greatly.
Polycaprolactone (PCL) is a kind of Biodegradable high-molecular polymkeric substance.Join the biocompatibility that can effectively improve nylon in the nylon segment, biodegradable, and the machine-shaping property of nylon products.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of mechanical property and other performances that can improve polymeric amide effectively for the defective that overcomes above-mentioned prior art existence, enlarges the random block polyamide material of polymeric amide range of application.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of random block polyamide material is characterized in that, this material comprises following composition and content (weight part): polymeric amide 200-950
Polycaprolactone 50-800.
Described polymeric amide is the mixture of two kinds or more of technical grade polymeric amide.
Described polymeric amide comprises Nylon6, and Nylon 66, and Nylon 11, and Nylon 12, the mixture of Nylon 4 and copolymer nylon.
Described polycaprolactone is the technical grade polycaprolactone.
Compared with prior art, the present invention has developed a kind of new polymer kind, has revised the processing characteristics of nylon at molecular level, and has kept its mechanical property; Utilize the amide-ester switching method to prepare random block polyamide material, can make up polymeric amide easily, improve mechanical property and other performances of polymeric amide effectively, enlarge the polymeric amide range of application by this method.
