The material of toughener is HDPE, LLDPE, EVA, PA, POE, PPB etc..

The preparation method of the antibiotic polypropylene master batch, the specific steps are that:

One, the preparation of bagasse whisker:

The bagasse cleaned up is taken, it is molten using the urea liquid progress of sodium hydroxide under the conditions of subzero 10~15 DEG C Solution after dissolution completely, using the method for ultracentrifugation, collects the sample of centrifugation bottom of the tube, then washed using deionized water It washs three times, then obtains bagasse whisker for 24 hours in 60 DEG C of vacuum drying；

In the urea liquid of sodium hydroxide, the mass fraction of sodium hydroxide is 3~8%, and the mass fraction of urea is 1.2 ~3%；

In ultracentrifugation technique, centrifugal force is 8000~12000g；

Holocellulos or content of lignin are up to 80% in bagasse, and the cellulose itself in bagasse have compared with The high degree of orientation can be significantly in certain arrangement, while by using hot-cold lysis in the aqueous slkali of current urea After removal impurity and the aqueous slkali for reducing the crystal whisker materials in cellulose for oriented crystalline, therefore passing through urea dissolve, lysate Natural cellulose whiskers material in middle reservation bagasse；And crystal whisker materials are being used for PP as a kind of excellent reinforcing material The fields such as tubing are widely used, and after cellulose whiskers, are reduced due in the glucose molecule structure in cellulose The dehydration of ehter bond and keep its heat resisting temperature low, easily charing and cause to decompose in plastic processes, cause reinforcing material intensity drop The problems such as low；Therefore Random fiber element is dissolved by the aqueous slkali of low temperature urea, obtains natural cellulose whiskers material, solved The low problem of its PP tubing intensity, while having many advantages, such as heat resisting temperature height and high intensity；To extend the service life of tubing.

Two, the preparation of bagasse whisker is activated:

Using the bagasse whisker of step 1 preparation as raw material, acidification activation processing is carried out to bagasse whisker, is then existed again Under the conditions of 60~80 DEG C, in the aqueous solution of edta edta, edta edta is made to be grafted on bagasse whisker On, it is dried in vacuo under the conditions of 60 DEG C again after filtering, activation bagasse whisker is prepared；

Acidification activation process is Strong oxdiative acidic mixed solution, and 3~6h is impregnated under the conditions of 80~90 DEG C；Strong oxygen Change the mixed solution that acidic mixed solution is nitric acid and hydrogen peroxide, wherein the mass concentration of nitric acid solution is 10~15%, dioxygen The mass concentration of aqueous solution is 10%~15%；

In the aqueous solution of edta edta, the mass fraction of edta edta is 4~8%；

In the grafting process, the graft reaction time is 1.5~2.0h；

Due to the hydroxyl structure containing glucose in the cellulosic structure of bagasse, it is anti-esterification can to occur with carboxylic acid structure It answers, is improved using esterification and the functionalization of cellulose itself is presently the most effective means；But there is also functions The function of material itself is difficult to merge with basis material, to influence processing performance；Therefore the application is by carrying out cellulose Acidification and oxidation processes improve hydroxyl activity in fibre structure using the strong oxidation of nitric acid and hydrogen peroxide, thus be conducive to Esterification occurs in water phase for EDTA, avoids since the EDTA carboxylic acid structure of aqueous solution is low with hydroxyl structure activity, esterification The problems such as rate is slow, and enzymatic synthesis condition is harsh；The EDTA structure introduced simultaneously can be good at carrying out complex reaction with metal ion, To improve the Heat-resistant stable performance of bagasse whisker, and since complex ion itself is in cellulose surface precipitating, to mention Its high functional effect and reinforcing effect.

Three, the preparation of antibacterial agent:

Activation bagasse whisker prepared by step 2 is added in copper nitrate solution, then adjusts mixed solution with nitric acid PH is 5.05~5.15, under 45~60 DEG C of stirring conditions, copper ion and activated biomass cellulose whiskers is made be complexed instead It answers, after being generated again without precipitating in solution to be mixed；Then adjusting pH is 6.0~6.5, then under 45~60 DEG C of stirring conditions, is added Enter magnesium nitrate solution, so that magnesium ion and activation bagasse whisker is carried out complex reaction, generate and stop without precipitating in solution to be mixed Reaction is collected sediment and is reacted for 24 hours in 60 DEG C of vacuum drying again, obtains antibacterial agent；

The mass values of the activation bagasse whisker and copper nitrate are 1:0.15~1:0.25；

The mass values of the activation bagasse whisker and magnesium nitrate are 1:0.10~1:0.15；
