Description
Technical field
The present invention is a kind of environment-friendly type composite wooden material antifungus agent and preparation method thereof, belongs to composite wooden material
Mildew-resistant field.
Background technology
The composite wooden materials such as plywood, fibre board, particieboard, owing to having good physical and mechanical property, processability
Can, obtain the attention of countries in the world and unprecedented development, be widely used in the fields such as building, interior decoration and automobile.
But, owing to composite wooden material has obvious biological characteristics, easily caused by the harm of bacterium, insecticide and microorganism sending out
Mould, rotten and damage by worms.Especially China the Changjiang river areas to the south hot humid, meets the suitable condition of mycete existence, to mycete
Grow and breed highly beneficial.Slightly going mouldy in early days occurs in composite wooden material surface, only affects outward appearance, but along with mycete
Development, mycelia can go deep into the inside to composite wooden material, and rot fungi also can grow up, and finally causes composite wooden material
Intensity reduces, and gradually loses use value.Meanwhile, when the mycotic spore in air reaches some, indoor inhabitation or work
Author there will be the symptom such as allergy, asthma.
For composite wooden material, effective mildew-resistant mode remains Chemical treatment.The mildew-resistant that tradition uses
Agent such as penta sodium pentachlorophenate and copper chromium arsenic, anti-mold effect is notable, moderate, but toxicity is high, it is relatively big to injure people and animals, Long Term Contact
Or use can cause serious environmental pollution, many countries to limit or have prohibitted the use of such antifungus agent.
In the environment-friendly type mixed solvents such as Bamboo vinegar solution, wood vinegar, CAOSU liquid, the organic acid substance that comprises, letones and
Alcohols material, has that anthelmintic sterilization is antibacterial waits effect it is considered to be natural antibacterial and insecticide.But bamboo-vinegar, wood vinegar
Stock solution, CAOSU stock solution be mainly composed of moisture, active constituent content is low, and when being used alone, anti-mold effect is the most notable, it is necessary to
Strengthen effective ingredient.The Chinese invention patent of Publication No. CN 1857882 A, with Bamboo vinegar solution as substrate, compounding Bravo, three
The effective ingredient such as oxazolone, boric acid, Borax, penta sodium pentachlorophenate, sodium dichromate, are prepared for a kind of novel bamboo and timber material anticorrosive mildewproof
Agent.The Chinese invention patent of Publication No. CN 101229645 A, compounds with Bamboo vinegar solution, wood vinegar, CAOSU liquid for main component
Zinc compound, copper-containing compound and cationic surfactant, it is thus achieved that the bamboo wood that a kind of toxicity is low, anticorrosive mildewproof is effective
Material Antisepticize and mildew preventive.Human body and the pollution of environment and toxicity are greatly reduced by both antifungus agents, but still exist compounding
The defects such as thing addition is big, production cost is high, poor stability.
Summary of the invention
The present invention is a kind of environment-friendly type composite wooden material antifungus agent and preparation method thereof, its purpose is to improve now
Have the antifungus agent deficiency at the aspect such as bio-toxicity, production cost, it is provided that a kind of environment-friendly type composite wooden material antifungus agent and
Its preparation method.
The technical solution of the present invention: a kind of environment-friendly type composite wooden material antifungus agent and preparation method thereof, it is special
Levy is that preparation method comprises the steps: containing natural Chinese medicinal herb and environment-friendly type solvent in antifungus agent
(1) herbal raw material is weighed according to formula proportion；
(2) by Chinese herbal medicine according to weight ratio (1 ~ 100): 1000, immersion 0 ~ 48 h it is placed in environment-friendly type solvent；
(3) the above-mentioned solvent being added with Chinese herbal medicine is placed in microwave oven, microwave 5 ~ 60 min；
(4) stir, cooling, complete the preparation of antifungus agent；
(5) composite wooden material is carried out mildew-resistant process, and carry out the evaluation of anti-mold effect.
Advantages of the present invention:
1) process is simple to operate, it is not necessary to complex device, and production efficiency is high；
2) process after composite wooden material fungicidal properties be improved significantly;
3) compared with existing chemical anti mildew agent, the most nontoxic to people and animals, more meet environmental requirement；
4) with single Bamboo vinegar solution, CAOSU liquid, wood vinegar solvent phase ratio, bacteriostasis is higher, and anti-mold effect is substantially improved；
5) compared with the complex preparation such as existing Bamboo vinegar solution, formula is more scientific rationally, does not especially use chemistry interpolation in formula
Agent, stability is more preferable, and cost is lower.
