Description
Technical field
The invention belongs to the additive technology fields of wood-based plate, and in particular to a kind of wood-based plate mould inhibitor.
Background technique
Wood-based plate is widely used in the upholstery etc. of Furniture manufacture, engineering construction, packaging material, vehicle and ship.
Since the raw material of production wood-based plate is usually the biological materials such as timber, wood shavings, fiber, straw, in a humidity environment, especially
It is in the damp and hot place in south, general fibre plate is placed in wet environment the deformation that can make moist, using being easier to mouldy and breed bacterium,
Its service life and using effect are not only reduced, but also can make one pathogenic due to the diffusion of mycotic spore.Use antibacterial agent, mould proof
Agent can effectively kill bacterium, mould, inhibit bacterium, the mold concentrations in people living space, improve indoor environmental quality, reduce disease
The generation of disease.Antibacterial is the growth and breeding for inhibiting microorganism and trophosome and the brood body of killing microorganism, shows as antibacterium
With antimycotic performance.The non-timber particieboard manufactured with plant materials such as cornstalk, wheat straw bars, though it is reachable on mechanical strength
To the level of wood planing card, but due to containing more sugar and starch substance in non-timber particieboard, bred conducive to mould,
Thus this kind of particieboard be easier to it is mouldy, influence using.Antibacterial mildew inhibitor can effectively kill bacterium, mould, inhibit people to live empty
Between bacterium, mold concentrations, improve indoor environmental quality, reduce the generation of disease.
Wood-based plate antimicrobial treatment multiselect antibacterial agent or mould inhibitor at present, antibacterial effect is fine, but to the gluing of plate
Intensity effect is larger, and there is secondary pollutions.The antimicrobial sheet material overwhelming majority of commercial type is all to decorate antibacterial on surface layer
Coating adds anti-biotic material in surface layer abrasion-proof paper, itself does not have antibacterial and mouldproof effect.Inorganic antiseptic has wide spectrum, height
The advantages that effect, low toxicity, bacterium can be effectively suppressed, but its fungicidal properties is not significant.Organic mould inhibitor is quick, sterilizing ability
By force, but mostly it is oily matter, is first not easy to disperse in glue, moreover be affected to the bonding strength of plate, and easily
Drug resistance is generated to microorganism, the disadvantages of that there are antibacterial times is short, easy to migrate, poor heat resistance；Efficacy of a drug release is concentrated when use, mistake
Big release concentration can cause damages to environment and the mankind.The antibacterial agent or mould inhibitor of one-component, only to a certain or
Several bacteriums or mould have particularly efficient killing effect, cannot all work to all bacterium.Therefore it need to develop a kind of mould proof
Effect and the strong wood-based plate mould inhibitor of fungistatic effect.
