Description

A container floor

technical field

The utility model relates to a container bottom plate, in particular to a container bottom plate with long service life, free from painting and high strength.

Background technique

At present, most of the surface and bottom plates used in the manufacture of container bottom plates are still processed and produced with wood and bamboo materials. Intensity of use, but also finishing treatment during use, the service life and strength of the bottom plate are all affected.

In "A Plywood for Container Bottom" with the notification number CN201012510Y, the utility model relates to a plywood for container bottom, including a core ply and upper and lower plies located on the upper and lower sides of the core ply, and the upper ply Including the upper panel layer and the upper middle layer between the upper panel layer and the core layer, the lower layer includes the lower panel layer and the lower middle layer between the lower panel layer and the core layer, and the core layer is particleboard or fiberboard , the upper and lower layers both include a wood veneer layer and a bamboo layer, a wood veneer layer is set between adjacent bamboo layers, the bamboo layer is a bamboo curtain or a bamboo mat, and the upper and lower middle layers include the upper and lower sides of the core layer. The wood veneer layers are connected by gluing and pressing between adjacent layers. The plywood of the utility model meets the use requirements of the container floor, can replace the container floor made of traditional Southeast Asian clone wood, reduces the production cost of the container floor, and is of great significance in reducing the harvesting of tropical hardwood such as Southeast Asian clone wood and protecting the environment. At the same time, it provides a new development direction for the industrial utilization of bamboo. However, since the upper and lower layers involved in this utility model patent are wood veneer layers or bamboo layers, the control requirements for surface quality are relatively high, and the control of strength and appearance quality is not very satisfactory.

In the invention patent of "a high-strength composite container floor plywood" whose publication number is CN1583526A, the container floor plywood includes a surface board, a long medium board and a core board, and the core layer of the plywood is medium density fiberboard or particle board, The surface board is tropical broad-leaved hardwood, and the arrangement of the veneers on both sides of the medium density fiberboard or particle board is symmetrical. Each layer of veneers from the innermost layer of long medium board to medium fiber board is arranged in the form of orthogonal combination. The use of tropical broad-leaved wood as raw materials results in a waste of high-quality wood resources, which is not in line with the consumption trend of ecology and environmental protection, and the use of ordinary particleboard and medium density fiberboard as the core layer has a poor overall strength.

Contents of the invention

Aiming at the problems existing in the prior art, the purpose of this utility model is to provide a container bottom plate, which can reduce the use of high-quality wood for the surface and bottom plate in the production process of the container bottom plate, so that the container bottom plate has the advantages of free painting and long service life and higher use intensity.

The technical solution of the utility model to solve the technical problem is: a container bottom plate, which includes a surface layer and a base material layer, the base material layer is located below the surface layer, and the surface layer and the base material layer are connected by an adhesive; The surface layer is an aluminum alloy plate; the substrate layer is one of oriented strand board, bamboo plywood or bamboo-wood composite board; the bamboo plywood consists of 10-17 bamboo curtains and/or bamboo mat layers Quality materials are glued together with a water-resistant adhesive; the bamboo-wood composite board includes a surface layer, a middle layer and a bottom layer. The bamboo curtains are assembled vertically and horizontally; the surface layer, the middle layer and the bottom layer are glued together.

The thickness of the surface layer is 0.5-5 mm; the thickness of the base material layer is 26-38 mm.

The thickness of the wood veneer in the bamboo-wood composite board is 1.2-2mm.

The thickness of the bamboo curtain in the bamboo-wood composite board is 1.5-3.5mm.

The beneficial effects of the utility model are: compared with the prior art, the container bottom plate provided by the utility model is formed by pressing through the secondary molding process, adopts an aluminum alloy plate as the surface layer, and is based on an oriented particle board or a bamboo material plate. The material layer reduces the requirement of the base plate for surface defects, and there is no need to spray paint when using it. The base plate has high strength and prolongs the service life of the base plate; at the same time, the aluminum alloy plate is used as the surface layer, which reduces the dependence on high-quality wood and has the characteristics of ecology and environmental protection. .
