Description
Technical field
The invention belongs to modified plastics technical fields, and in particular to a kind of plastic additive with bacteriostasis.
Background technology
The main component of plastics is resin.This noun of resin is initially the lipid secreted out of by animals and plants and gains the name, such as
Rosin, shellac etc., resin refer to the high-molecular compound not yet mixed with various additives.Resin accounts for about plastics total weight
40%~100%.The basic performance of plastics depends mainly on the person's character of resin, but additive also plays an important role.Some plastics
It is substantially made of synthetic resin, is free of or contains less additive, such as organic glass, polystyrene.
Additive generates strong influence to the performance of plastics, can be generated to the performance of plastics using different additives bright
Aobvious influence, in food plastic applications, preservative film is a kind of highly important category, in order to promote the biocidal property of preservative film
Can, it often adds bacteriostatic agent in the plastic now, much uses silver ion additive now, but it is of high cost, safety is opposite
It is relatively low, it can not be ensured again using the stability of plant bacteriostatic agent.
Invention content
The purpose of the present invention is for existing problem, provide a kind of plastic additive with bacteriostasis, this Shen
The volume bacteriostatic agent antibacterial bacteriostatic performance that please be prepared is good, stability and safe.
The present invention is achieved by the following technical solutions：
A kind of plastic additive with bacteriostasis, preparation method include the following steps：
（1）The preparation process of garlic oil-beta cyclodextrin clathrate；
20 parts of deionized waters are added into 1-2 parts of beta cyclodextrins, aqueous solution is made, 1 part of addition is anhydrous into 0.2-0.3 portions of garlic oils
Ethyl alcohol dissolves, and is then added drop-wise in the aqueous solution of beta cyclodextrin, mixed solution is carried out inclusion 1-2h under the conditions of clathrate process,
Crystallisation by cooling, vacuum filtration, after being washed with absolute ethyl alcohol, dry at normal temperatures garlic oil-Benexate Hydrochloride；
（2）The preparation of the antibacterial film liquid of caryophyllus oil-sodium alginate；
0.5-1 parts of caryophyllus oil ethanol solutions are added in 10-15 parts of sodium alginate solns, are stirred evenly, then with 0.3-0.4 parts
Hydrophobic ingredient, 0.2-0.3 part emulsifier are uniformly mixed, and obtain the antibacterial film liquid of caryophyllus oil-sodium alginate；
（3）Ingredient compounds；
By step（1）Obtained garlic oil-Benexate Hydrochloride and step（2）Obtained caryophyllus oil-sodium alginate bacteriostatic film
Liquid is uniformly mixed, and obtains additive.
Step（2）Middle hydrophobic ingredient is the hydrophobing agent of Henan Zhong Jie chemical products Co., Ltd production.
The step（2）Middle sodium alginate soln is the sodium alginate soln that mass fraction is 45%.
The emulsifier is ethoxylated dodecyl alcohol or phenethyl phenol polyethenoxy ether.
The present invention has the following advantages compared with prior art：
Garlic oil has antibacterial, antiviral and antitumor, protects cardiovascular system, promotes glycometabolism, improves the works such as immunity of organisms
With；Garlic oil is included with beta cyclodextrin, inclusion compound has no irritating odor, and shows that good thermal stability, light are stablized
Property and the long-term stability that keeps sample, fully meet follow-up film forming and require.Caryophyllus oil is added in sodium alginate layer and makees bacteriostatic agent, with
Beeswax is hydrophobic ingredient, block-water effect is strong, and the emulsifying effectiveness using S40 as emulsifier, to beeswax is good, and caryophyllus oil makes the water-resistance of film
Increase, organoleptic properties, barrier property and the good mechanical property of film.The antibacterial additive of the application passes through the place to material composition
Reason so that the stability of bacteriostatic agent is high, after capable of adding in the plastic, promotes the bacteriostasis property of plastics, and due to carrying out
Embedding treatment etc. can make the stability higher of bacteriostatic agent, can extend the antibacterial period of bacteriostatic agent.
Specific implementation mode
A kind of plastic additive with bacteriostasis, preparation method include the following steps：
（1）The preparation process of garlic oil-beta cyclodextrin clathrate；
