Abstract

The invention provides a bamboo-wood composite container base plate with improved bamboo curtain splint surface layers, and a manufacturing method thereof. The bamboo-wood composite container base plate with improved bamboo curtain splint surface layers is characterized in that each half of the bamboo-wood composite container base plate comprises an improved bamboo curtain splint surface layer, two to three bamboo curtain splints (or two to three wood single boards) and wood single board with transverse textures, wherein the improved bamboo curtain splint surface layer, the two to three bamboo curtain splints (or two to three wood single boards) and the wood single board with transverse textures are orderly arranged from outside to inside; the bamboo curtain splints and the wood single board with transverse textures are arranged at intervals from outside to inside; the bamboo curtain splints can be replaced by wood single boards and when the bamboo curtain splints are replaced by wood single boards, the innermost three wood single boards have longitudinal textures; and phenolic resin impregnated material layers are arranged at the outermost sides of the bamboo-wood composite container base plate with the improved bamboo curtain splint surface layers. The manufacturing method comprises the following steps of 1, treating the wood single boards to enable the wood single boards to have water content less than or equal to 10%, coating double surfaces of each one of the wood single boards with glue, and aging or drying at a low temperature, and 2, assembling the wood single boards, the improved bamboo curtain splint surface layers, the bamboo curtain splints and the phenolic resin impregnated material layers to obtain a plate blank and carrying out hot pressing under the conditions of a temperature of 130 to 150 DEG C and the maximum pressure of 2.0 to 3.5MPa. The bamboo-wood composite container base plate with the improved bamboo curtain splint surface layers has the advantages that the improved bamboo curtain splint surface layers prepared from thin bamboo chips having the same width through a novel splicing technology are adopted and thus a container base plate prepared from the bamboo-wood composite container base plate with the improved bamboo curtain splint surface layers is beautiful and has good wear resistance, stable quality and all performance indexes such as intensity and elastic modulus according with technical requirements of the international container industry.

Description

A kind of to improve bamboo wood composite container baseboard and the manufacture method of bamboo curtain splint as top layer
Technical field
What the present invention relates to is a kind of to improve bamboo wood composite container baseboard and the manufacture method of bamboo curtain splint as top layer, belongs to the wood-based plate manufacturing technology field in timber industry.
Background technology
The main loaded area of container is base plate, and container manufacture requires base plate to have very high mechanical property, presentation quality, impact resistance and ageing-resistant performance.Existing bamboo wood composite container baseboard has two kinds of forms: patent ZL 98111153.x mesexine is a kind of bamboo wood composite container baseboard that impregnated paper adds bamboo mat, another patent ZL 03152841.4 mesexine is the high-density bamboo material thin layer that hot pressing forms through high pressure, is then composited for core secondary hot pressing with structural particleboard or board using poplar board etc. as table backing layer with it again.The first, in order to obtain beautiful outward appearance, needs impregnated paper and bamboo mat, and bamboo mat braiding needs more cost of labor, and the surface quality of base plate is not high; Though rear one also can meet the requirements of mechanical property and acceptable outward appearance, owing to being post forming, also need its cemented surface sanding gluing, then it is compound to pass through secondary hot pressing, consume the more energy, material and labour.All there is high in cost of production problem in these two kinds of bamboo wood composite container baseboards, case east is difficult to accept.
Summary of the invention
The present invention is to provide a kind of to improve bamboo wood composite container baseboard and the manufacture method of bamboo curtain splint as top layer, its objective is that utilizing improvement bamboo curtain splint is top layer, by special wide thin bamboo plate and Novel splicing mode, can wait until the surface layer that surface gaps is less, by the uniform phenolic impregnated material of compound one deck color, make and there is evenly attractive in appearance, fine and close wear-resisting surface layer again of color, have again the composite bottom board of bamboo wood high-intensity performance.
Technical solution of the present invention: it is characterized in that from outside to inside to being called one deck hard paper, one deck improvement bamboo curtain splint, two-layer longitudinal texture bamboo curtain splint; Be inwardly cross grain veneer and the longitudinally alternate laying of texture veneer again, intermediate layer is except longitudinal texture veneer, and totally 13 layers, middle three layers are longitudinal texture, and remaining is by a cross grain veneer and the alternate laying of a longitudinal texture veneer.
Described improvement bamboo curtain splint is that bamboo cane is processed into wide bamboo chip by special equipment, after being dried, is used line, thin bamboo plate, thin veneer, nonwoven etc. to make compared with small gap.
Phenolic impregnated material can be impregnated paper, also can be immersion non-woven fabrics, also can be dipping glass-fiber-fabric.
Manufacture method comprises following processing step:
A, Wooden veneer, bamboo curtain splint sorting, dry, arrangement, Wooden veneer moisture content≤10%, to Wooden veneer double spread, glue-spread 250~350g/m 2, in glue, add glue to weigh 15% flour filler, ageing or low temperature drying; Wide bamboo chip is weaved into bamboo curtain splint or will be spelled tight bamboo chip glue jail with several veneer veneers with line etc., and all bamboo curtain splints are dried to moisture content below 12%, dipping phenol glue low temperature drying below 20%, add appropriate pesticide to moisture content in glue;
B, assembly, hot pressing, by veneer, bamboo curtain splint and impregnated paper assembly, be 130~150 ℃ in temperature, carries out hot pressing under the condition that maximum pressure is 2.0~3.5MPa, keeps then pressure drop stage, steam discharge, release 30~45 minutes; Or lead to cold water, release after heating platen is cooled to 70 ℃ or 80 ℃ in heating platen.
Advantage of the present invention: can effectively utilize China and timber all over the world, as the various softwoods of wildwood and artificial forest, broadleaf timber, and have that growth is fast, the cycle is short, can cut selectively every year, bamboo timber resource that the sustainable utilization time is long.These Material claddings are used, design and reasonably combination through science, both can solve the difficulty of hardwood resource scarcity in world wide, can solve again the technical barrier of the Novel bottom plate of producing to meet the requirement of trans-container industrial technology in enormous quantities.By the closely knit improvement bamboo curtain splint application in surface, the bamboo mat of purchase is changed into the improvement bamboo curtain splint oneself customizing, surface quality and the stability of product have simultaneously
Institute improves.
Special wide bamboo chip is woven into bamboo curtain splint (or with several veneer veneers etc. will spell tight bamboo chip glue jail) by the present invention, then by being composited with bamboo curtain splint, veneer.In glue used, all should add pesticide, uniformly penetrating is in the surface material of container bottom board in the time of hot pressing to make it, and base plate has long-acting insect protected performance like this; Core material and surface material are combined into slab, then make container bottom board through hot-press gluing, the property indices such as its intensity, elastic modelling quantity, surface quality, can meet the technical requirement of trans-container industry completely.
