Layer raw material；
(2) plastic substrate 100 parts, bamboo fibre 20～40 parts, coupling agent 2～5 parts are weighed by weight,
First plastic substrate is mixed homogeneously with coupling agent, add bamboo fibre and continue mix homogeneously, obtain sandwich layer former
Material；Weigh ethylene-vinyl alcohol copolymer 100 parts as barrier layer raw material；
(3) top layer raw material, core layer raw material, barrier layer raw material are separately added in three extruders, melted
Being expressed in same co-extruding mould, wherein core layer raw material is positioned at centre, and barrier layer raw material is positioned at core layer raw material
Surrounding by core layer raw material cladding get up, top layer raw material is positioned at the surrounding of barrier layer raw material by barrier layer raw material
Cladding is got up, and is then passed through cooling down, shapes, cuts and obtain described antibiosis layered board.
Preferably, described bamboo fibre, before use through drying and processing, makes moisture content be less than 0.05%.
Preferably, during in described step (3), top layer raw material adds double screw extruder, extrusion temperature is

Antibacterial, obstruct filler plasticizer first are mixed homogeneously to add with coupling agent by top layer raw material and moulds
Material matrix and antioxidant continue mix homogeneously, and antibacterial, obstruct filling surface can be made preferably to be located
Reason, increases and the compatibility of plastic substrate in extrusion.
Plastic substrate is first mixed homogeneously with coupling agent by core layer raw material, adds bamboo fibre and continue mixing all
Even, owing to plastic substrate raw material mostly is pellet, after pellet is mixed homogeneously with coupling agent, surface viscosity increases
Add, can preferably adhere to bamboo fibre, thus avoid bamboo fibre to float on plastic substrate in mixed process
The surface of pellet, causes mixing uneven, affects the performance of core material.
Compared to the prior art, the beneficial effects of the present invention is:
(1) antibiosis layered board of the present invention is made up of trilaminate material, and sandwich layer cross section is rectangle, depends on outside sandwich layer
Secondary it is coated with barrier layer and top layer, core material uses bamboo fibre material overall rush can be greatly improved
Hit, stretch, the mechanical property such as bending, bamboo fibre itself has certain antibacterial, antibacterial, sterilization simultaneously
Effect, therefore sandwich layer also has certain antibacterial effect；And play the skin-material of main antibacterial action,
Through formula design, there is good anti-bacterial effect, the feature of antibacterial action length in lasting service life；Barrier layer material
Material is provided simultaneously with gluing and the effect preferably intercepted, resistance for EVOH for the material of top layer and sandwich layer
Being come in top layer and sandwich layer obstruct of interlayer prevents mutually migrating and shadow between core material and skin-material
Ringing, so that the antibacterial time of antibiosis layered board is more lasting, antibacterial effect is more preferable.
(2) top layer of the present invention uses photocatalyst-type inorganic antiseptic as antibacterial, use lamellar without
Machine filler is as intercepting filler, after flaky inorganic filler is dispersed in skin-material system, Ke Yiqi
To certain iris action, the antimicrobial component in skin-material is made to be discharged into antimicrobial composite material slowly
Surface, thus extend effective antibacterial time of antimicrobial composite material.
(3), in antimicrobial composite material of the present invention, there is no the antibacterial of silver ion series, use three layers simultaneously
The technical scheme of co-extrusion, is used for the table of composite board by skin-material best but relatively costly for antibacterial effect
Face, and the antibacterial effect as the sandwich layer of supporting role is slightly worse, cost is relatively low, significantly reduces raw material
Cost.
