Abstract
The nano antiseptic plastic master batch and its application that the invention discloses a kind of with bionic function, the plastic master batch is made of following parts by weight of component: 1 ~ 10 part of lubricant, 1 ~ 30 part of antibacterial agent, 80 ~ 100 parts of polycaprolactone resin, 1 ~ 10 part of sodium carboxymethylcellulose, 1 ~ 10 part of calcium carbonate, 1 ~ 30 part of starch, 1 ~ 10 part of chitosan, 1 ~ 10 part of fibroin albumen.The polycaprolactone resin that the master batch selects biocompatibility high is basis material, reduces human body repellency；The addition of antibacterial agent can reduce the incidence of postoperative wound infection, promote the healing of wound.Mother particles of antibacterial plastics disclosed by the invention for operation suture thread has many advantages, such as simple production process, and processability is good and can continuous large-scale production.
Description
Technical field
The present invention relates to a kind of technical field of polymer composite materials, and in particular to a kind of nanometer with bionic function is anti-
Bacterium material and its application.
Background technique
Operation suture thread refer in surgical operation or wound disposition in, be used for hemostasis by ligation, Suture hemostasis
And the Special Linear material of tissue suture.There are many type of operation suture thread, can be divided by material type natural, synthesis
With metal suture line.Since synthesis suture has the characteristics that intensity is big, tissue reaction is small, easy disinfection, suture is become
Center.Developing new synthetic fibers suture and being modified to existing suture is the emphasis studied from now on.
Antibiotic plastic be it is a kind of in use environment itself to stain on plastics bacterium, mould, alcohol mother bacterium, algae very
The plastics that inhibition or killing effect have been waited to virus keep itself clean by inhibiting the breeding of microorganism.Currently, antibacterial is moulded
Material is mainly obtained by the method for adding a small amount of antibacterial agent in common plastics.
Currently, surgical operation postoperative infection and its caused complication clinically still occupy biggish ratio, to trouble
The rehabilitation of person especially gerontal patient brings unfavorable factor.Therefore, it is badly in need of developing a kind of be made of antibiotic plastic while can be with
Reduce the antibacterial operation suture of postoperative infection.Antibiotic plastic is applied to the development of operation suture thread, will further widen plastics
In the application range of medical field.
Summary of the invention
In order to overcome the deficiencies of the prior art, present invention aims at: a kind of nano-antibacterial material with bionic function is provided
Material.
A further object of the present invention is to provide the applications of the above-mentioned nano anti-biotic material product with bionic function.This hair
It is bright to adopt the following technical scheme that
A kind of nano anti-biotic material with bionic function, the master batch are made of following parts by weight of component: 1 ~ 10 part of lubricant, being resisted
1 ~ 30 part of microbial inoculum, 80 ~ 100 parts of polycaprolactone resin, 1 ~ 10 part of sodium carboxymethylcellulose, 1 ~ 10 part of calcium carbonate, 1 ~ 30 part of starch,
1 ~ 10 part of chitosan, 1 ~ 10 part of fibroin albumen.
The lubricant is glycerol.
The antibacterial agent is the inorganic antiseptic of argentiferous, zinc, copper one or more of them metallic element.
The polycaprolactone resin as matrix resin, 50 DEG C of vacuum drying treatments for 24 hours.
The present invention provides the application that the above-mentioned nano anti-biotic material with bionic function of one kind is used to prepare operation suture thread.
The polycaprolactone resin that the present invention selects biocompatibility high is basis material, reduces human body repellency；Antibacterial agent
Addition can reduce the incidence of postoperative wound infection, promote the healing of wound.It is disclosed by the invention for operation suture thread
Mother particles of antibacterial plastics has many advantages, such as simple production process, and processability is good and can continuous large-scale production.
The beneficial effects of the present invention are:
1. the present invention polycaprolactone high for the mother particles of antibacterial plastics selection biocompatibility of operation suture thread is as matrix tree
Rouge, reduces the rejection of human body, and the addition of antibacterial agent can reduce the incidence of postoperative wound infection, promote the healing of wound.
2. antibiotic plastic of the present invention has widened plastics in the application range of medical field for operation suture thread.
3. the present invention has simple production process for the mother particles of antibacterial plastics of operation suture thread, non-environmental-pollution, can connect
The features such as continuous property scale industrial production.
Specific embodiment
The present invention is described in detail below by specific example, but protection scope of the present invention is not only restricted to these
Examples of implementation.
Embodiment 1:
A kind of nano anti-biotic material with bionic function, is made of following parts by weight of component: 5 parts of glycerol, carboxymethyl cellulose
