Problems solved by technology

[0003] In the patent ZL93115652.0 of the production method of bamboo container floor, the method cuts the bamboo into strips of equal width and thickness, arranges the strips in parallel, puts them into the mixed solution of preservative and phenolic resin, and then laminates them. Pressurized, the bamboo container floor produced can pass the test requirements of international containers, but the utilization rate of bamboo is low, the manufacturing is complicated, and the processing efficiency is low, which leads to the high cost of bamboo container floor, limited production capacity, and cannot be used on a large scale.

Embodiment 1

[0049] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of the bottom plate of the container shown in Embodiment 1.

[0050] The bottom plate of the container is made by the following methods:

[0051] (1) Spread the continuous glass fiber, compound it with the extruded and melted polypropylene resin matrix, and then roll to obtain a fiber-reinforced thermoplastic prepreg tape. The mass percentage of the fiber in the prepreg tape is 40%, and the thickness of the single layer 0.50mm, take 4 layers and lay them up alternately at 0-90 degrees, and then heat-press the fiber-reinforced thermoplastic prepreg tape and a layer of PET non-woven fabric into a sheet at a temperature of 180°C and a pressure of 4MPa. The hot pressing time is 20 minutes, and then the cold pressing is performed for 30 minutes to obtain the fiber-reinforced thermoplastic sheet, that is, the surface layer 1 and the bottom layer 3;

Embodiment 3

[0066] Such as image 3 as shown, image 3 It is a structural schematic diagram of the bottom plate of the container shown in Embodiment 3.

[0067] (1) Spread the continuous glass fiber, compound it with the extruded and melted polypropylene resin matrix, and then roll to obtain a fiber-reinforced thermoplastic prepreg tape. The mass percentage of the fiber in the prepreg tape is 50%, and the thickness of the single layer 0.50mm, take 4 layers and lay them up alternately according to 0 / 90 degrees, and then heat-press the fiber-reinforced thermoplastic prepreg tape and a layer of PET non-woven fabric into a sheet at a temperature of 170°C and a pressure of 3MPa. The hot pressing time is 30 minutes, and then the cold pressing is performed for 40 minutes to obtain fiber reinforced thermoplastic sheets, that is, the surface layer 1 and the bottom layer 3;

[0068] (2) Moso bamboo is cut to form strip-shaped bamboo strips; the bamboo strips are unidirectionally arranged in paral...

Abstract

The invention discloses a container baseboard. The container baseboard sequentially comprises a surface layer, a sandwich layer and a bottom layer from top to bottom, wherein upper and lower surfaces of the sandwich layer are respectively connected with the surface layer and the bottom layer. The invention further discloses a method for preparing the container baseboard comprises the following steps: paving the sandwich layer on the upper surface of the bottom layer, paving the surface layer on the upper surface of the sandwich layer, and performing hot pressing composite to prepare the container baseboard. The density, strength, elasticity modulus, surface quality and various property indexes of the container baseboard can meet a composite container baseboard with industry standards of the international container, and the container baseboard has strong design, and can reasonably select thickness and density of the surface layer, the bottom layer and the core material according to actual demands, thereby realizing the best economic effect.

Description

technical field [0001] The invention relates to the technical field of manufacturing container bottom plates, in particular to a glass fiber reinforced bamboo composite plate container bottom plate and a preparation method thereof. Background technique [0002] The container floor is the main load-bearing structure of the container. The container floor manufacturing industry requires the floor to have high mechanical properties, precise processing dimensions, and good impact resistance. For a long time, the container floor mainly uses high-density hard broad-leaved wood grown in tropical rain forests as the main raw material. After being cut into veneers by large-diameter logs, multi-layer veneers are formed into embryos and hot-pressed into plywood. Since the growth cycle of high-density broad-leaved tree species is very long, it generally takes 50 years or even longer, and the demand for container floor is increasing day by day. In order to protect the world's ecological ...
