Description
Technical field
The present invention relates to a kind of preparation methods of fire-retardant anti-mildew container bottom board, belong to transport field of material technology.
Background technique
With flourishing for modern transportation industry, the demand of container is significantly increased, and which also promotes container bottom boards
The fast development of industry.China has become container bottom board and produces the first big country at present.It is hard to clone the tropical rain forests such as wood, A Bidong
Carpentery workshop is the main raw material(s) of conventional container bottom plate, has the characteristics that high mechanical properties, anti-corrosion, insect prevention.But due to supply
The quick reduction of the shortage of the tropical rain forest hardwood of ground south east asia, the hardwood resource such as Ke Longmu, A Bidong seriously constrains
The development of container bottom board industry.In view of this severe situation, relevant scientific research personnel is considered as other artificial forest fast-growings
Timber replaces traditional hardwood to prepare container bottom board.
Container is constituted by steel plate, paint and as carrying, buffering, shockproof bottom plate-part of thickness glued board three.Collection
Necessary accessory of the vanning bottom plate as container, demand is synchronous with the development of container.According to container bottom board table
Face situation can be classified as two major classes: a kind of surface is Wooden veneer；Cover phenolic resin impregnated paper in another kind of surface.Container
The thickness of bottom plate is generally 28mm, and breadth specification is more complicated, generally depending on body structure.Regular size is generally
20 feet and 40 feet two kinds.
Different from the use occasion of general decor glued board or building template glued board, container bottom board is mainly used for
Transportational process, it is necessary to have the performances such as good antidetonation, impact resistance, weatherability, ageing-resistant.Therefore, other than apparent size,
Very high requirement is proposed to physical properties such as the bonding durability of composite board for bottom board of container, static bending strength, elasticity modulus.
The use condition of container bottom board requires it that must have the property such as good weatherability, impact resistance, ageing-resistant, antidetonation
Can, other than apparent size reaches requirement, to the bending property, bonding strength and durability etc. of composite board for bottom board of container
The requirement of physical and mechanical property is very high.Therefore, the requirement to container floor material is also just correspondingly relatively stringenter.It is below
Once used baseboard material in container development process.Shaped steel plate bottom plate has enough compression strength and rigidity, processing
The advantages that haveing excellent performance, but there is also following two major defects: and in identical compression strength, steel sole plate will increase container
Self weight, seriously reduce the loading transport capacity of ship；Bottom plate system consolidates cargo difficult, and its cost is relatively high.For making
Standby non-traditional Hard―Wood used for bottom plate of container mainly includes the domestic artificial forest wood such as larch, birch, eucalyptus.It is this kind of
Artificial forest wood various aspects of performance is all more excellent, but there is presently no obtain promoting and large batch of use.Its reason is except biography
Outside the factors such as the more excellent performance and use habit of system bottom plate, the high expensive of main or such bottom plate.Synthetic material bottom
Plate is the superior performance using plastics as primary raw material, but raw material sources are limited, higher cost, not yet realization large-scale production.In foreign countries
People, which are making great efforts to develop, some can substitute other materials hardwood material and with environment protection significance.China is carrying out bamboo
Substitute the research and test of tropical Hard―Wood.Currently, bamboo wood container bottom board production line has had been established.But bamboo wood bottom plate
Higher cost, quarantine problems are complicated, and to the material thickness of different bamboo kinds, method for anticorrosion treatment and the scope of application have different want
It asks, technology controlling and process is more complex.
Compared with normal plywood, the production technology characteristic of composite board for bottom board of container mainly has the following:
(1) since product need to have preferable water-fast and weather resistance, the adhesive used is often phenolic resin glue；
(2) plate expansion is changed in product requirement dash board, core plate and length；
(3) thickness of packaging composite board for bottom board is generally 28mm；
(4) veneer thickness of composite board for bottom board of container is related with the number of plies, and veneer thickness is generally 1.6~2.1mm, ply
Number is often 15,17,19 layers 3 kinds；
(5) commonly using tree species is the Hard―Woods such as A Bidong, clone, Okoume；
(6) since the product is more demanding to longitudinal strength, longitudinal veneer number of plies is required to be more than lateral veneer in assembly
The number of plies；(7) product must have certain antiseptic property, so specific anti-corrosion measure is needed in the process of producing product,
Common anticorrosive is that halogen is red；
(8) product surface requires have certain wear-resisting, scratch resistance, to handle surface, common method is
Surface coating is carried out with phenolic resin or polyurethane etc., to achieve the purpose that increase its wear-resisting, scratch resistance.
Currently, China come into widely apply artificial forest wood stage, in order to efficiently utilize artificial forest wood and
Intermediate cutting should be improved such as intensity, durability etc., to meet using function from the material of soft artificial forest first
It is required that.It is needed to improve alkali resistance, acid resistance, anti-flammability, natural corrosion resistant (moth) property, dimensional stability and the mechanical strength of timber
Will physics, mechanics, chemical property and construction feature to timber improved or changed by physically or chemically working process.Through
The timber for crossing modification claims innovation wood or improvement wood.It is traditionally more not timber and glued board, wood shavings through protective treatment
The scope that though there is plate etc. the property of certain improved woods to be included in improved wood.
