Description
Technical field
The present invention relates to a kind of mold-proof method of material, more particularly to a kind of mold-proof method of Wood plastic composite, belong to
Timber treatment technology field.
Background technology
Wood plastic composite be with plant fiber powders such as plastics, wood powders as primary raw material, along with other auxiliary agents are extruded,
A kind of advanced composite material (ACM) of the technological formings such as molding, injection, it have be not cracked, indeformable, corrosion-resistant, plasticity is strong, energy
Particularly simple realize that personalized moulding, high-environmental, pollution-free, nuisanceless, product are free of the materials such as benzene, formaldehyde, are recycled
Utilize, be a kind of brand-new Green Product, be also a kind of ecological clean composite, just causing in the last few years more next
More concerns.Wood plastic composite can be used as the packaging material such as pallet, packing case, the storage material such as bed board, paving beam, house,
The leisure material such as outdoor tables and chairs, stool that the occasions such as the finishings such as floor, building template, ornament materials, park, court, street are used
Material, automobile inside decoration materials, tubing etc..
Wood plastic composite in use, can usually occur the situation of surface from mildewing, general processing mode Shi Sumu factories
Family adds chemical anti mildew agent or the mould proof composition feelings mouldy to reduce product surface when product is produced in formula
Condition.
But this method has following shortcoming：
1st, mould inhibitor is a kind of biocide, and addition in the product, with the use of product, can be produced certain to environment
Harmful effect.If species and adding proportion are improper, can also certain harm be caused to human body and environment；
2nd, mould inhibitor is relatively costly, and mould inhibitor is intended merely to prevent product surface mouldy, but is added in product formula
Mould inhibitor causes that product entire body contains mould inhibitor, and those additions mould inhibitor that center portion is divided in the material does not play effect, wastes
Cost.
The content of the invention
The purpose of the present invention is directed to the defect of prior art presence, proposes a kind of mold-proof method of Wood plastic composite,
It is surface-treated by Wood plastic composite, reduces the Signs of Mould of material surface.
Biological mould proof treatment does not influence not only on human body and environment, while simplifying process step, has saved cost.
The present invention solves technical problem by the following technical programs：The mold-proof method of Wood plastic composite, including by fungi
Solution and culture medium are dissolved in the water in proportion, are made biological mildew inhibitor；The biological mildew inhibitor is sprayed in confined space to enter
Row fungal culture is used as biological mould proof room；Wood plastic composite is placed in biological mould proof room and treats that fungi runs out of plastic-wood material
After nutriment in wood powder, the mould proof treatment of Wood plastic composite is completed.
Fungi in the fungi solution of the above method includes koning trichoderma, trichoderma pseudokiningii, Trichoderma atroviride, spine spore wood
Mould, tangerine green trichoderma, trichoderma aureoviride.
Fungal spore concentration is (0.1~1) × 10 in the fungi solution6CFU/ml。
The culture medium include peptone, beef extract, bean sprouts, potato, flour, soluble starch, sucrose, glucose,
Maltose.
The concentration of the culture medium is (0.1~1) g/L.
25 DEG C~30 DEG C of the temperature of the biological mould proof room, relative humidity more than 85%.Preferably, the biological mould proof room
Inside set wind circulating system.
The biological mildew inhibitor is by peptone 0.35g, dehydrated potato powder 0.35g and concentration 1 × 106The Kang Shi wood of CFU/ml
Mould stoste 100ml is obtained in being dissolved in 1L water.
The reason for modeling wood products surface from mildewing is that mould is touching modeling wood products surface free bag in air or environment
During the wood-fibred for covering, grow under certain environmental conditions, cause product surface to change colour.
Modeling wood products are put into mould proof room and are pre-processed by the present invention, in advance in some the easy lifes of modeling wood products surface seeding
Grow, endanger low, non-discoloring fungi, the nutriment in the wood powder of consumption modeling wood products surface.Treat that product surface nutriment disappears
After the completion of consumption, these fungies are most of dead, so that nutriment of the modeling wood products surface without fungus growth, while
Remaining a part of fungi also has certain rejection ability to the growth of mould, and fungicidal properties is substantially improved.These are true simultaneously
Bacterium is the type being widely present in natural environment, does not have any influence to human body and environment.
Advantages of the present invention is as follows：
1. prevent product mouldy using biotechnology, overcome the mould proof environmental risk of conventional chemical method and high cost
Shortcoming；
2. the characteristics of make use of Wood plastic composite surface wood-fibred limited amount, is disappeared nutriment using fungi in advance
Consumption, breaks off mould production environment；
3. the suppression principle that make use of fungi to grow, promotes beneficial bacteria growing, suppresses harmful bacteria growing；
4. biomembrane principle make use of, and fungi passes through the breeding and growth of itself, gradually all surfaces of covering product, i.e.,
After making to be subjected to rainwater or friction loss, moreover it is possible to gradually recover.The mould proof middle surface mould inhibitor of chemistry is overcome with rain water runoff
Afterwards, the situation of fungicidal properties reduction.
5. modeling wood products are processed using mould proof room, make fungi own growth in suitable environmental conditions, be not required to
Biological mildew inhibitor is persistently prepared, further simplifies operation.
