Wood fibre 100%,
Adhesive 8%~12%,
Antiseptic and antibiotic agent A 0.25%~1%,
Antiseptic and antibiotic agent B 0.25%~0.5%,
Emulsified wax 1%~2%;
Wherein, the wood fibre is over dry wood fibre, and type is Ginkgo wood and poplar, wherein ginkgo wood-fibred accounting 10%
~30%, surplus is aspen fibers by using silicon;
The adhesive is mixed by isocyanates and E0 grade urea-formaldehyde resins, and wherein isocyanates accounts for adhesive mass percent
40~60%, remaining is E0 grade urea-formaldehyde resins;
The antiseptic and antibiotic agent A is mixed by ethanol amine copper and dimercaptodimethyl ammonium chloride, wherein ethanol amine copper mass hundred
Divide ratio 60%~70%, remaining is dimercaptodimethyl ammonium chloride;
The antiseptic and antibiotic agent B is boric acid.
The invention also discloses the manufacturing process for making the anti-corrosive antibacterial fiberboard, including following process:
A, prepared by antiseptic and antibiotic agent:Ethanol amine copper and dimercaptodimethyl ammonium chloride are put in proportion into the water to 40~45 DEG C
In, the antiseptic and antibiotic agent A of active ingredient 1%~3% is made until dissolving in stirring;Boric acid is put into stirring container, is constantly added
Add 45~55 DEG C of water, until being completely dissolved, antiseptic and antibiotic agent B, the i.e. saturated solution of boric acid is made;
B, procedure for preparation:Ginkgo wood and poplar are passed through respectively peeling, slice, screening, washing and etc. be processed into qualified wood
Piece, and poplar wood chip is dried to moisture content 2%~4%;
C, poplar wood chip preservative treatment:The antiseptic and antibiotic agent A prepared is placed in vacuum impregnation pressurized tank, first -0.05
30~60min is impregnated under conditions of~-0.1Mpa;Then 2~3h is impregnated under conditions of 1.0~2.0Mpa;Finally -0.05
20~30min is impregnated under conditions of~-0.1Mpa, takes out wood chip;Wherein optimal processing condition is:First in the item of -0.08MPa
30min is impregnated under part, and 2.5h is then impregnated under conditions of 1.6MPa, 30min is finally impregnated under conditions of -0.06MPa;
D, heat mill process:Ginkgo wood chip and poplar wood chip Jing Guo preservative treatment are worn into fiber respectively;
E, it is glued process:Fiber after defibrator process is mixed in proportion, antiseptic and antibiotic agent B is first uniformly applied to fiber
In, then emulsified wax and adhesive are uniformly applied in fiber;
F, drying process:By the fiber drying after sizing to moisture content 8%~11%;
G, hot pressing process:Fiber of the sizing after dry is placed in precompressed grinding tool, after precompressed, send into hot press and carries out hot pressing
Molding, wherein hot pressing temperature are 180~210 DEG C, and hot pressing time is 20~30smm-1, using Discrete control, wherein section of boosting
Total hot pressing time 1~3% is accounted for, high pressure section accounts for total hot pressing time 15~25%, and decompression section accounts for total hot pressing time 15~20%, exhaust section
Total hot pressing time 35~40% is accounted for, secondary booster section accounts for total hot pressing time 2~5%, and fixed thickness section accounts for total hot pressing time 15~20%, lets out
Pressure section accounts for total hot pressing time 3~6%;
H, cooling, grade, pack.
The fiberboard anti-corrosion grade obtained by the manufacturing process has reached 1 grade according to the present invention, i.e., weight-loss ratio 10% with
Under, it is most corrosion resistant grade, antibiotic rate is 95% or more, and physical and mechanical property is better than"It is moist in GB/T 11718-2009 standards
The furniture type medium density fibre board (MDF) used under state"Performance requirement, burst size of methanal is in 3mg/100g hereinafter, having taken into account fiberboard
Anti-corrosive antibacterial performance, physical and mechanical property and environmental requirement.
The present invention is using Ginkgo wood and poplar as wood material, and Ginkgo wood has natural anticorrosion effect, and poplar hole is big, anti-corrosion
Agent easily infiltrates into, and preservative adhesive rate is high.Boric acid has good antisepsis, but boric acid leach resistance is poor, therefore selects
It is added in Process of Applying Glue, improves the utilization rate of boric acid.Ethanol amine copper has preventive and therapeutic effect, didecyldimethylammonium to a variety of fungies
Ammonium chloride has killing and inhibiting effect to fungi, moth, termite etc.;Ethanol amine copper can be reacted with the group in timber, can be stablized
Ground be attached in timber not by it is water-soluble go out;Dimercaptodimethyl ammonium chloride also can occur ion exchange with wood component and consolidate
Determine in wood without flowing out, since ethanol amine copper, dimercaptodimethyl ammonium chloride leach resistance are good, after preservative treatment
Wood chip is after heat mill process, and not only preservative is lost in few, but also preservative is fully combined with timber, to the physical mechanics of fiberboard
Performance influences small.It selects three kinds of boric acid, ethanol amine copper, dimercaptodimethyl ammonium chloride substances as antiseptic and antibiotic agent, and applies
Mode is different, not only increases the anti-corrosive antibacterial effect of fiberboard, and influence very little to the physical and mechanical property of plank.Selection
Isocyanates, Lauxite not only ensure that the physical and mechanical property of plank, while reducing and being produced into as enhancing adhesive
This.
Raw material used in the present invention is technical grade, commercially available, wherein E0 grade urea-formaldehyde resins are derived from big sub- wood-based plate collection
Danyang factory of Co., Ltd of group, E0 grade urea-formaldehyde resin physical and chemical indexes are:PH value 8.5~8.9, solid content 54.5~56.5%, viscosity
15.5~17.5s, hardening time≤200s, free formaldehyde≤0.1%, water Combination >=0.5;Isocyanates is graceful poly- purchased from Hensel
Urethane(China)Co., Ltd.
Advantageous effect
Manufacturing process process disclosed in this invention is relatively simple, and using Ginkgo wood and poplar as wood material, Ginkgo wood has day
Right antisepsis selects three kinds of boric acid, ethanol amine copper, dimercaptodimethyl ammonium chloride substances as antiseptic and antibiotic agent, and applies
Mode is different, not only increases the anti-corrosive antibacterial effect of fiberboard, and influence very little to the physical and mechanical property of plank.
