Abstract
The utility model relates to a plywood for shipbuilding. The plywood comprises a surface layer, core layers and a bottom layer, wherein the surface layer, the core layers and the bottom layer are closely combined through adhesives, a piece of impregnated paper is arranged on the surface layer, the number of the surface layer is one, the number of the core layers is nine, the number of the bottom layer is one, and the thickness of the surface layer, the thickness of the core layers and the thickness of the bottom layer are respectively 15mm. Bamboo wood materials which are abundant in China are utilized in the plywood, and bamboo wood which is extensive in source and relatively low in cost is compounded with wood through reasonable process means.
Description
Technical field
The utility model relates to a kind of glued board, relates in particular to a kind of shipbuilding special glue plywood.
Background technology
The boats and ships glued board is because its special environment for use requires glued board to have intensity height, good weatherability, water-fast good corrosion resistance.Boats and ships with glued board generally adopt intensity high revolve veneer processed, surface backplate floods pure dissolubility phenolic resins, central layer is coated with water soluble phenol resin, and the high strength that hot-press gluing forms under elevated pressures, enhanced water resistance glued board revolve veneer processed and generally adopt Eucalyptus or pine to produce.
The strength ratio of bamboo wood is higher, and the tensile strength parallel to grain of bamboo wood is 2-25 times of timber, and compression strength perpendicular to grain is 1.5-2 times of timber.Bamboo wood is the characteristic resources of China, and domestic bamboo grove area reaches 5,000,000 hm2, and bamboo afforestation is success once, also can cut selectively every year, and continuous utilization and do not destroy ecological environment is the optimal selection of filling up the timber shortage.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, provide a kind of and meeting boats and ships with under the prerequisite of Strength of Plywood, utilize the bamboo timber resource of China's abundant, by rational process means wide material sources and cheap relatively bamboo wood are carried out compound shipbuilding special glue plywood with timber.
Technical scheme: in order to solve the problems of the technologies described above, a kind of shipbuilding special glue plywood described in the utility model, it comprises surface layer, sandwich layer and bottom, combine closely by adhesive between them, be provided with impregnated paper on described surface layer, described surface layer is one deck, and described sandwich layer is nine layers, described bottom is one deck, and the thickness of described surface layer, sandwich layer and bottom is 15mm.
Described surface layer and bottom all are single wood plate layer.
Described sandwich layer is made up of veneer and bamboo veneer, arranges bonding between them in length and breadth in order and forms.
Described surface layer adopts any one in the seeds such as Okoume, rock sugar fruit, birch.
Described bottom adopts any one in the seeds such as big whitewood, Okoume, birch.
Described impregnated paper is the resin impregnating bond paper that contains the alundum (Al powder.
Described bamboo veneer is for being bamboo curtain splint or bamboo mat.
Described binding agent is the resorcinol resin modified phenol resin.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the structural design of the utility model by optimizing, the artificial forest fast growing wood that material is relatively poor carries out compound with the higher bamboo wood of intensity, promoted the intensity of vertical and horizontal, thereby bring into play the maximum performance of various materials, obtain shipbuilding bamboo wood composite veneer rationally; Because bamboo wood and artificial fast growing wood wide material sources, cost is lower, the lower to a great extent production cost of boats and ships glued boards; Adopted the resorcinol modified phenolic resin adhesive, can improve curing rate, reduced solidification temperature, enhanced productivity, adopt the glued board of this adhesive production just have good weather, water-fast, bonding strength is high, hot-water soak was not come unglued in 72 hours; The top layer posts the resin impregnating bond paper that contains alundum (Al, has given boats and ships with the good wearability of glued board.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein:
1, surface layer; 2, sandwich layer; 3, bottom; 4, impregnated paper
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the total number of plies of shipbuilding special glue plywood described in the utility model is 11 layers, and it comprises surface layer 1, sandwich layer 2, bottom 3 and impregnated paper 4; Described surface layer 1 is provided with impregnated paper 4, closely connects between them; Described surface layer 1 is made up of one deck veneer; Described sandwich layer 2 is made up of 9 layers of veneer and bamboo veneer, arranges bonding between them in length and breadth in order and forms; Described base plate 3 is made up of one deck veneer; Described surface layer 1, the gross thickness of sandwich layer 2 and bottom 3 is 15mm; Described surface layer 1 veneer adopts seeds such as Okoume, rock sugar fruit, birch; Bottom 3 adopts seeds such as big whitewood, Okoume, birch; The veneer of described sandwich layer 2 is by adopting Eucalyptus veneer and bamboo veneer; Be 1.7mm with Eucalyptus rounding to thickness, be dried to moisture content＜8%, Okoume thickness 1.0mm is selected on the top layer, be dried to moisture content＜8%, bottom is selected big whitewood, and thickness is 1.2mm, be dried to moisture content＜8%, the bamboo veneer is bamboo curtain splint, and thickness is 2.0mm, and low temperature drying is to moisture＜13% behind the impregnation.The utility model processes through gluing, assembly, hot pressing etc., described sandwich layer from top to bottom be followed successively by vertical veneer, vertically the bamboo veneer, laterally veneer, vertically veneer, vertically veneer, vertically veneer, laterally veneer, vertically the bamboo veneer, vertically veneer, carry out colding pressing behind the assembly at last, can obtain the boats and ships glued board after hot pressing, saw limit, the sanding.The structural design of the utility model by optimizing, the artificial forest fast growing wood that material is relatively poor carries out compound with the higher bamboo wood of intensity, promote the intensity of vertical and horizontal, thereby brought into play the maximum performance of various materials, obtained shipbuilding bamboo wood composite veneer rationally; Because bamboo wood and artificial fast growing wood wide material sources, cost is lower, the lower to a great extent production cost of boats and ships glued boards; Adopted the resorcinol modified phenolic resin adhesive, can improve curing rate, reduced solidification temperature, enhanced productivity, adopt the glued board of this adhesive production just have good weather, water-fast, bonding strength is high, hot-water soak was not come unglued in 72 hours; The top layer posts the resin impregnating bond paper that contains alundum (Al, has given boats and ships with the good wearability of glued board.
The utility model provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications; these improvements and modifications also should be considered as protection domain of the present utility model, in the present embodiment not clear and definite each part all available prior art realized.
