Description
Technical field
The present invention relates to a kind of particieboard, more particularly to a kind of compound moulding plane produced using bamboo shaving and crushed straw aggregate
Card and preparation method thereof, belong to field of composite material preparation.
Background technology
Agricultural crop straw wide material sources, it is a kind of valuable renewable resource, mainly in the form of agricultural production byproduct
Obtain.It is estimated that at present national agricultural crop straw annual production more than 800,000,000 tons, wherein about 700,000,000 tons of recyclable stalk resource.
Agricultural crop straw was once the main animal feeding-stuff and life fuel in China rural area.But due to the raising and production of the rural area level of production
The transformation of mode, and the requirement of Environmental Protection Situation, the Land use models of stalk are needed badly and are adjusted.However, by China for a long time with
Agriculture Production Modes to be formed are influenceed, and the scale collection system of agricultural crop straw is not completely set up.Meanwhile agriculture at this stage
Crop material utilization ways variation degree is relatively low and technology and immature.Therefore, agricultural crop straw utilization ways are more at this stage
Sample degree is relatively low and technology and immature.Therefore, it is limited to the digestion capability of agricultural crop straw.Still there are a large amount of stalks to adopt at present
Handled with the mode directly burned, not only cause the waste of a large amount of valuable biomass resources, also cause all kinds of environment
Pollution and the generation of fire and traffic accident.As a kind of lignin fibre raw material, agricultural crop straw is used for particieboard
Preparation is an effective way for realizing its higher value application.
At present, the exploration to stalk-shaving board manufacturing technology has been achieved for good progress, and also has industrialized production
Example is seen in report.However, stalk is different from lumber fibre, its fiber is elongated, there is a cavity, and there is a wax coat on surface, soft texture,
It is directly used in wood-based plate and easily weakens timber intensity.Therefore, stalk-shaving board at this stage is by its sheet material mechanical strength is relatively low, plate
The restriction of the problems such as easy warpage in face, moisture protection difference, it is difficult to realize large-scale industrialized production.Therefore, by stalk and other originals
Material coordinates making laminated particle-board to be to manufacture one of good feasible way of particieboard of combination property.Such as patent
A kind of method that CN105965658A discloses Wheat Straw and wooden shavings composite manufacturing particieboard, thereon layer select wheat straw
Stalk wood shavings, sandwich layer select wooden shavings, and plate property is optimal when Wheat Straw wood shavings ratio reaches 35-45%.Although the above method
Plate property is improved, but has still used a large amount of timber resources, this low feature of stalk cost can not be given full play to.And for example
Patent CN101947804B and CN106079015A individually disclose stalk and magnesia and magnesium chloride is mutually compound and by stalk
With the compound method for preparing wood-based plate of basalt fibre.Above-mentioned two patent has used the higher inorganic matter of price, sheet material into
This is of a relatively high.
Bamboo wood receives the extensive concern of wood working industry because of its good mechanical property.Bamboo wood and stalk composite manufacturing
Wood-based plate is also the active path for improving stalk-shaving board combination property.As patent CN103538138B discloses a kind of bamboo wood weight
The preparation method of group material stalk brick and bamboo glulam stalk brick, its using bamboo wood recombinant material or bamboo glulam as outer layer, with
Stalk brick manufactures composite board as internal layer.And for example patent CN102699976A discloses a kind of bamboo chip or bamboo cane, stalk are compound
Plate, bamboo chip or bamboo cane are arranged in inside sheet material by it manufactures composite plate to have the function that to strengthen sheet material mechanical property.The above two
Though bamboo wood and stalk composite manufacturing sheet material can not be utilized path bamboo wood or bamboo processing leftover bits and pieces by example patent.Meanwhile
Larger-size two kinds of raw material compound tenses, its interracial contact is inevitable smaller, can not realize that effect enhancing maximizes.It is in addition, existing
Some stalk-shaving boards largely employ isocyanate resin (MDI) and are used as adhesive to reach no aldehyde effect, itself and farming
Thing stalk has good bonding capacity, and resin added is low, curing rate is fast, hot pressing temperature is low, sheet material water-tolerant, but because
Its with multiple material can good gluing, often occur " haftplatte " phenomenon in sheet material hot pressing, i.e., raw material crushed straw aggregate,
Fiber and metal caul, heating platen are bonding, cause the inconvenience in production technology.
