Abstract
The preparation method that the invention discloses a kind of modified algae amortizing packaging material, after being pulverized by the Thallus Laminariae (Thallus Eckloniae) cleaned up, puts into immersion 0.5 ~ 6h in the hydrochloric acid that mass fraction is 1 ~ 5%, and deionized water cleans, and filters; It is then placed in the sodium ion solution that mass fraction is 1 ~ 15%, after soaking 1 ~ 6h, in-20 DEG C ~-80 DEG C freezing 6 ~ 12h; Again at 0.5 ~ 4Pa, at-80 ~-45 DEG C, vacuum lyophilization is to constant weight, obtains modified algae amortizing packaging material. The present invention is using Fresh Laminaria Japonica as raw material, and it is extensively easy to get. Preparation technology is simple, adopts vacuum freeze-drying method that raw material can be made to produce loose structure by water sublimed without any blowing promotor when, has excellent shock-absorbing capacity and degradation property, light weight. And preparation process do not produce by-product, it is to avoid environmental pollution.
Description
Technical field
The preparation method that the present invention relates to a kind of modified algae amortizing packaging material, especially relates to a kind of method preparing amortizing packaging material for raw material by vacuum freeze-drying method with Fresh Laminaria Japonica.
Background technology
At packaging field, the amortizing packaging material used the earliest has dividing plate, Waste paper strip etc., owing to its shock-absorbing capacity is undesirable and is replaced by foam plastics. Foam plastics prepares under high-temperature and high-pressure conditions by adding various blowing promotors, preparation process can produce the noxious substances such as bisphenols, and environment can be produced serious pollution owing to being difficult to degraded, so degradable buffering package material becomes a kind of new development trend.
Summary of the invention
The preparation method that it is an object of the invention to provide a kind of light weight, the good and biodegradable modified algae amortizing packaging material of shock-absorbing capacity.
The preparation method of the modified algae amortizing packaging material of the present invention, step is as follows:
After being pulverized by the Thallus Laminariae (Thallus Eckloniae) cleaned up, putting into immersion 0.5 ~ 6h in the hydrochloric acid that mass fraction is 1 ~ 5%, deionized water cleans, and filters; It is then placed in the sodium ion solution that mass fraction is 1 ~ 15%, after soaking 1 ~ 6h, in-20 DEG C ~-80 DEG C freezing 6 ~ 12h; Again at 0.5 ~ 4Pa, at-80 ~-45 DEG C, vacuum lyophilization is to constant weight, obtains modified algae amortizing packaging material.
In the present invention, described sodium ion solution is aqueous sodium carbonate or sodium hydrate aqueous solution.
In the present invention, the degree of grinding of Thallus Laminariae (Thallus Eckloniae) is not specially required, be generally crushed to 50 order～200 orders.
The present invention is using Fresh Laminaria Japonica as raw material, and it is extensively easy to get. Preparation technology is simple, adopt vacuum freeze-drying method that raw material can be made to produce loose structure by water sublimed without any blowing promotor when, having excellent shock-absorbing capacity and degradation property, light weight, the foam plastics of alternative contaminated environment is as the amortizing packaging material of commodity. And preparation process do not produce by-product, it is to avoid environmental pollution.
Accompanying drawing explanation
Fig. 1 is the section microscope figure of modified algae amortizing packaging material prepared by the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.

(3) utilize deionized water to clean, after filtration, the aqueous sodium carbonate of the mass fraction 15% of 50ml soaks 3h;
(4) mechanical agitation 5min, freezing 6h at-80 DEG C of temperature;
(5) vacuum lyophilization under 0.8Pa ,-80 DEG C of conditions of the Thallus Laminariae (Thallus Eckloniae) after freezing reaches constant weight taking-up, prepares modified algae amortizing packaging material.
Embodiment 3:
(1) in pulverizer, it is crushed to 200 orders with the rotating speed of 2500r/min after being cleaned by Fresh Laminaria Japonica;
(2) more broken for 50g Thallus Laminariae (Thallus Eckloniae) is soaked in the hydrochloric acid of the mass fraction 5% of 50ml 6h;
(3) utilize deionized water to clean, after filtration, the sodium hydrate aqueous solution of the mass fraction 1% of 50ml soaks 6h;
(4) mechanical agitation 10min, first freezing 6h under-20 DEG C of cryogenic temperatures, then freezing 6h at-80 DEG C of temperature;
(5) vacuum lyophilization under 4Pa ,-45 DEG C of conditions of the Thallus Laminariae (Thallus Eckloniae) after freezing reaches constant weight taking-up, prepares modified algae amortizing packaging material.
