Abstract
The invention discloses a method for manufacturing straw composite materials by adopting bio-adhesive. The method includes the steps of 1), inoculating bio-adhesive generating strains on a PDA culture medium and placing the strains under the constant temperature ranging from 10DEG C to 40DEG C for culture; 2), smashing straws to 10-100 in mesh, adding water 1-3 times as much as straws, adjusting pH value to be 3-6, inoculating the bio-adhesive generating strains on the wet straw powder, culturing for 5-30 days under the temperature of 10-40DEG C, and allowing microorganism generating the bio-adhesive to have the straw powder adhered by the aid of biological adhesion generated during growth of the microorganism; 3), subjected to the straw composite materials shaped by adhesion to dry stripping to obtain the straw composite materials good in buffer performance. The method is simple in manufacturing, energy saving and environment friendly, wide in source of raw materials, fully satisfied to disposable packaging, biodegradable and good in extensive use.
Description
Technical field
The present invention relates to a kind of method manufacturing stalk compound material using biological binding agent.
Technical background
Modern goods expanding economy promotes the circulation of commodity, for avoiding the breakage during Commodity Transportation, buffers packet
Package material is widely applied.Foam plasticss become most widely used due to having good shock-absorbing capacity and vibration absorbing performance
Padded coaming, it has, and lightweight, easy processing, protective value are good, wide adaptability, good and cheap the features such as.But, due to bubble
The volume of foam plastics is big, garbage is unable to weathering, burning disposal can produce harmful gass, and environment is caused with very big danger
Evil.Although having now been developed degredation plastic at present, this plastics are expensive, and the condition of degraded requires strictly, no
Method is extensively applied.
Content of the invention
The invention provides a kind of method manufacturing stalk compound material using biological binding agent.
Present invention aim to address using foam plasticss as amortizing packaging material on existing market, discarded foam plasticss
High risks can be caused to environment, and degradation plastic is because expensive, degradation condition is strictly it is impossible to wide variety of ask
Topic.
The technical solution adopted for the present invention to solve the technical problems is：A kind of compound using biological binding agent manufacture straw
The method of material, including following preparation process：
Step one, generation binding agent strain is inoculated in PDA culture medium, is placed in 10-40 DEG C of constant temperature culture；
Step 2, crushed stalk to 10-100 mesh is subsequently adding the water of powder of straw weight 1-3 times, adjusts pH to 3-6,
By cultured product binding agent microbial inoculant in wet powder of straw, cultivate 5-30d, the micro- life of generation binding agent in 10-40 DEG C
Powder of straw is bonded by thing using the biological cementation producing in growth course；
Step 3, the stalk compound material of molding bonded is dried the demoulding, that is, be obtained and have comfort cushioning performance
Stalk compound material.
Further, described generation binding agent strain is Agaricus edibilis or the Pleurotaceae in basidiomycetes.
Further, described straw includes agricultural crop straw and herbage straw.
Further, it is inoculated in the 5-10% producing binding agent microbial biomass about dry straw grain weight amount in wet powder of straw.
The invention has the beneficial effects as follows：Production process of the present invention is simple, energy-conserving and environment-protective, and raw material sources are extensive.Institute of the present invention
The material structure that the method stated is obtained is loose, and plasticity is big, make the material during amortizing packaging material be easier to pulverize and
Compressing, making amortizing packaging material toughness is strong, appropriate density, intensity are higher, can fully meet non-returnable container needs；And
Will not be to human body and environmental pollution during processing, use；Product is easily handled after using, and enters environment 60～90 days
After can be degraded by microorganisms completely, enter soil after, become good plant growing nutrient, soil fertility can be increased, be one
Plant environmentally friendly biomass composite.
Brief description
Fig. 1 is the FB(flow block) of the present invention.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples：
As shown in the figure, there is provided the present invention manufactures the embodiment of the method for stalk compound material, bag using biological binding agent
Include following preparation process：
Step one, pleurotus funguses Pleurotus ostreatus is inoculated in solid slope PDA culture medium, in 28
DEG C constant temperature culture 5d, strain be positioned over after covering with inclined-plane 4 DEG C standby.The strain having activated is inoculated in solid plate culture medium
On, in 28 DEG C of constant temperature culture 4d, strain covers with flat board, you can be used for stalk compound material preparation as producing strain.Activate
Strain also can access in 500mL triangular flask, liquid culture base unit weight in triangular flask is 100mL, and the triangular flask connecting kind is put
Enter in rotational oscillation incubator, rotating speed is set to 170rpm, in 28 DEG C of constant-temperature shaking culture 3d, that is, Pleurotus is obtained
The liquid spawn of ostreatus.Wherein, PDA culture medium is：Rhizoma Solani tuber osi 200g, sucrose 20g, water 1000mL；If preparing solid
Culture medium, needs to add agar, and agar consumption is 15g；The sterilising temp of culture medium is 121 DEG C, and the time is 30min.
Step 2, crosses 50 mesh sieve, powder of straw for produce is obtained after rice straw is pulverized.Weigh powder of straw
1000g, water 2500g, concentration is 10% hydrochloric acid 100mL；Hydrochloric acid is added to the water, then water is mixed homogeneously with powder of straw,
Again the Pleurotus ostreatus liquid spawn of 100mL is added in wet powder of straw, mix homogeneously again.By consolidating of preparing
Body substrate will enter in mould, keep suitable tightness, then mould be placed in 25 DEG C of thermostatic chamber；After 7d, mould is beaten
Open, powder of straw molding again under the biological binding agent effect that Pleurotus ostreatus produces.
Step 3, by the straw material of molding again under the biological binding agent effect producing in Pleurotus ostreatus
Material is removed from the molds, and is less than 10% through drying to water content, that is, the straw composite packaging material with certain shape has been obtained
Material.
Described generation binding agent strain can also be the Agaricus edibilis in basidiomycetes.
Described straw includes agricultural crop straw and herbage straw.
Production process of the present invention is simple, energy-conserving and environment-protective, and raw material sources are extensive.The material knot that method of the present invention is obtained
Structure is loose, and plasticity is big, and the material during making amortizing packaging material is easier to pulverize and compressing, makes buffering package
Toughness of material is strong, appropriate density, intensity are higher, can fully meet non-returnable container needs；And will not during processing, use
To human body and environmental pollution；Product is easily handled after using, and enters environment and can be degraded by microorganisms completely after 60～90 days,
After entering soil, become good plant growing nutrient, soil fertility can be increased, be that a kind of environmentally friendly biomass is combined
Material.
