Description
Technical field
The present invention relates to a kind of preparation method of artificial board, especially a kind of preparation method of antibacterial and mouldproof particieboard.
Background technique
Particieboard is an important board kind in wood-based plate, and compared with other plate kinds, its investment of production is relatively fewer, energy consumption
Small, at low cost, the requirement to material quality is not also high, and three surplus objects, fast growing wood, recycling waste and old wood and some non-wooden materials are all
It can be used as the raw material of particieboard, therefore have its unique advantage in the Chinese development particieboard industry of timber resources scarcity.Plane
It is the graininess for intersecting structure straggly inside card, the performance in each portion direction is essentially identical, and lateral bearing capacity is good；Surface of chipboard
Smooth, texture is true to nature, and bulk density is uniform, and thickness error is small, and anti-pollution is ageing-resistant, beautiful, can carry out various veneers；Particieboard exists
In production process, glue consumption is smaller, and environmentally friendly coefficient is relatively high.Since particieboard volume is larger, with its Hepplewhite, relatively
For other plates, also than heavier.Because particieboard have it is so many a little, therefore it is widely used in Furniture manufacture, building, packet
Dress, the interior decoration of vehicle and ship and household appliance shell production etc., can also make facing particieboard through secondary operation.But
Being is wooden product due to particieboard, if keeping ventilation not in time on rainy day, it is easy to it is deformed because of air humidity,
Even have that mouldy, the situations such as addle, causes indoor stale taste serious, and particieboard majority is to be glued by Eucalyptus monolithic by adhesive
It ties, bow warping can be made to deform because generating expansive force difference after long-time moisture absorption.
Summary of the invention
It is anti-to provide a kind of antibacterial for the defects of the purpose of the present invention is to solve particieboard fungicidal properties is poor in the prior art
The preparation method of mould particieboard.
The present invention is achieved by the following technical solutions:
A kind of preparation method of antibacterial and mouldproof particieboard, includes the following steps:
S1: sawdust, wood shavings, useless bamboo fiber are chosen, silt, dust and iron filings class impurity are removed by screening and magnetic；
S2: the raw material of step S1 is crushed, and blender is transported to, and distillation bamboo vinegar, addition are sprayed when in whipping process
Amount is the 5-15% of raw material absolute dry mass；
S3: the resulting raw material of step S2 is sent into high-temperature heat treatment machine, handles 30min-- under the conditions of 120-200 DEG C
150min；
S4: will be sent into chip dryer through step S3 treated raw material, dry to moisture content 3-6%；
S5: the raw material after drying is sent into sizing applicator, applies antibacterial and mouldproof adhesive；
S6: mat formation；
S7: saw is cut out；
S8: hot pressing.
Preferably, the antibacterial and mouldproof adhesive includes the component of following parts by weight: adding MDI isocyanate adhesive 20-
40 parts and antibacterial mildew inhibitor 10-20 parts.
Preferably, the antibacterial mildew inhibitor includes the component of following parts by weight: 20-30 parts of mint extract, Radix Isatidis mention
Take 10-20 parts of object, active 20-61 parts of powdered carbon, 15-20 parts of bamboo charcoal powder, 10-20 parts of garlic powder and 5-12 parts of chilli powder.
Preferably, active powdered carbon, bamboo charcoal powder, garlic powder and the chilli powder cross 300 meshes.
Preferably, the distillation bamboo vinegar is that the fume gas condensation that cooling bamboo charcoal or Machine-made bamboo charcoal carbonization process generate obtains
Thick bamboo vinegar, air-distillation or the distillation bamboo being evaporated under reduced pressure at a temperature of 60 DEG C~80 DEG C at a temperature of 170 DEG C~190 DEG C
Vinegar liquid.
Wherein, the large specific surface area of active powdered carbon and bamboo charcoal powder, dampproof effect with super strength, to absorb the water in air
Point, avoiding timber main body from having, mouldy, the situations such as addle.Main component allicin in garlic has sterilization, desinsection, removing toxic substances, prevents
Corruption and other effects；And the main component capsaicine in capsicum is obvious to the action of contace poison of pest, i.e. table after pest contacts with capsaicine
Now benumb (inactive, not feeding), the final dead phenomenon of paralysis.Active powdered carbon, bamboo charcoal powder, garlic powder and chilli powder are as anti-
Worm mould inhibitor is added in composite urea formaldehyde resin adhesive of the present invention, and vermins-proof effect is lasting, does not influence the bonding strength of adhesive,
It is uniformly dispersed in adhesive, can be permeated with glue to wood internal, product is made to reach the function of long-acting insect prevention, it is prior
It is the safe and efficient low toxicity of these types of substance, there is certain antiseptic property.
The beneficial effect of particieboard of the invention is: carrying out high-temperature heat treatment before dry, makes starch, the sugar inside raw material
Point, the ingredients denaturation such as albumen, nutritional ingredient needed for destroying mould, while the bacterium that raw material itself is carried or infected kills,
And mildew-proof function is played, meanwhile, apply antibacterial and mouldproof adhesive, further increases the effect of antibacterial and mouldproof.
