Abstract
The present invention discloses a kind of bamboo wood anti-mould and anti-moth inorganic agent and preparation method thereof and construction technology, belongs to bamboo wood anti-mould and anti-moth processing technology field.The anti-mould and anti-moth inorganic agent is first to react nano-silver loaded isocyanation esterification graphene oxide with ethanol amine, then react and be prepared with Kocide SD.The construction technology is to carry out an Immersion treatment to bamboo wood first with anti-mould and anti-moth prepared by the present invention processing agent dispersing liquid, then carry out secondary Immersion treatment to bamboo wood with aqueous polyurethane.Anti-mould and anti-moth inorganic agent prepared by the present invention and the construction technology of offer can not only significantly improve the anti-mould and anti-moth and anti-mould and anti-moth stability of bamboo wood, and the hardness, wearability and dimensional stability of bamboo wood can be increased substantially, there is significant economic value and social benefit.
Description
Technical field
The invention belongs to bamboo wood anti-mould and anti-moth processing technology fields, and in particular to a kind of bamboo wood anti-mould and anti-moth inorganic agent and its
Preparation method and construction technology.
Background technique
Bamboo wood has the characteristics that resourceful, growth cycle is short, renewable, economic value is high, wood-based plate, composite plate,
The fields such as ornament materials, furniture, automobile manufacture are widely used.But due to bamboo wood and its product processing, transport and
Mildew, rotten and damage by worms frequent occurrence in use process, causes the performances such as its intensity, hardness to be greatly lowered, affects bamboo wood
Be widely used.Therefore, the anti-mould and anti-moth of bamboo wood is for the efficient using with vital meaning of bamboo resource.Currently, anti-
The method that only bamboo wood goes mouldy and damages by worms is mainly physical method and chemical method.Physical method is easy to operate, at low cost, but insecticidal effect
Difference.Chemical method mainly passes through Chemical treatment, kills the mould and existing pest infected in bamboo wood with chemical agent,
But also bamboo wood can be protected not corroded by bacterium worm.Water-soluble mould inhibitor is current most widely used mould inhibitor, is had non-stimulated
Property smell, the features such as processing material surface is clean, cheap, but the resistance leachability of water-soluble mould inhibitor is poor.The molten mould inhibitor of oil,
Such as pentachlorophenol, Bravo have the advantages such as mould proof ability is strong and persistence is good, but its processing cost is high, malicious to people and animals
Property is larger.Ma Hongxia (Ma Hongxia, He Xuexiang, Chen Lifang, Zhang Yanjun；Several mould inhibitors study Cluster Bamboo anti-mold effect, the world
The communication of bamboo rattan, 2013,11 (4): 11-15) use self-control compounding mould inhibitor to carry out mould proof processing to Cluster Bamboo D.farinosus.Research
The result shows that compounding mould inhibitor has preferable anti-mold effect.But that there are usage amounts is more for compounding mould inhibitor, higher cost has
The disadvantages of effect ingredient is easy to run off.
Summary of the invention
Mildew easily occurs in use for current bamboo wood, damages by worms and the problems such as mechanical properties decrease, the present invention is mentioned
For a kind of bamboo wood anti-mould and anti-moth inorganic agent and preparation method thereof and construction technology.Anti-mould and anti-moth inorganic agent prepared by the present invention and
The construction technology of offer can not only significantly improve the anti-mould and anti-moth and anti-mould and anti-moth stability of bamboo wood, but also can be significantly
Hardness, wearability and the dimensional stability of bamboo wood are improved, there is significant economic value and social benefit.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of anti-mould and anti-moth inorganic agent be nano-silver loaded isocyanation esterification graphene oxide is first reacted with ethanol amine, then
It reacts and is prepared with Kocide SD.
The preparation method of the bamboo wood anti-mould and anti-moth inorganic agent the following steps are included:
(1) 1~5g nano-silver loaded isocyanation esterification graphene oxide is added to 100~500mL N, N- dimethyl methyl
In amide, 30~90min of ultrasound, prepares nano-silver loaded isocyanation esterification graphene oxide dispersion at room temperature；- 5~5
DEG C and argon gas protection under, 20~200mL ethanolamine solutions are added drop-wise to nano-silver loaded with 20~60 drops/min speed dropwise
In isocyanation esterification graphene oxide dispersion, 12~36h of mechanic whirl-nett reaction is centrifuged, washs and is dried in vacuo, system
Standby nano-silver loaded ethanol amine grafted graphene oxide；
(2) 1~4g nano-silver loaded ethanol amine grafted graphene oxide is added in 100~400mL water, at room temperature
30~90min of ultrasound prepares nano-silver loaded ethanol amine grafted graphene oxide dispersion liquid；Point 1~8 time by 1~8g hydroxide
Copper is added in nano-silver loaded ethanol amine grafted graphene oxide dispersion liquid, at room temperature after 20~60min of ultrasound, is warming up to
30~60 DEG C, mechanic whirl-nett reaction 12~for 24 hours, it is centrifuged, washs and is dried in vacuo, prepare the grafting of nano-silver loaded amine copper
Graphene oxide, the as described anti-mould and anti-moth inorganic agent.
The nano-silver loaded isocyanation esterification graphene oxide is first according to document (Lin Rongquan；A kind of loading nano silvery
Graphene antibiosis composite material and preparation method, Chinese invention patent, application number: 201710886162.3) prepare nanometer
Silver load graphene oxide, further according to document (Yang Hongjun, Jiang Zhenqi, Bai Tao, Xue little Qiang, Huang Wenyan, Jiang Bibiao；Graphene/poly-
The synthesis and characterization of urethane composite material, polymer material science and engineering, 2016,32 (5): 28-32) utilize diphenyl-methane two
Isocyanates and nano-silver loaded graphite oxide alkene reaction are prepared.
In the nano-silver loaded isocyanation esterification graphene oxide, the weight percent of nano silver is 20~29%, different
The weight percent of cyanate group is 4.2~5.5%.
The concentration of the ethanolamine solutions is 50g/L, and solvent is n,N-Dimethylformamide.
