Abstract

The utility model relates to a glass fiber reinforced formaldehyde-free plywood, which is characterized in that it comprises wooden veneers on both sides and a middle core board between the two wood veneers, and the wood veneer and the middle core board are sandwiched A glass fiber layer is provided, and the glass fiber layer is glued between the middle core board and the wood veneer by a formaldehyde-free film-like thermoplastic wood adhesive. The glass fiber reinforced formaldehyde-free plywood can greatly improve the strength of the plywood. Under the condition of ensuring the strength of use, the thickness of the veneer is reduced, wood is saved, the weight is reduced, and the flame retardancy of the board is improved, and formaldehyde pollution is completely eliminated. It is healthy, environmentally friendly, economical, The social benefit is obvious, and it has a broad market prospect.

Description

A glass fiber reinforced formaldehyde-free plywood

technical field

The utility model relates to a glass fiber reinforced formaldehyde-free plywood.

Background technique

At present, plywood is widely used in furniture and home decoration. In order to ensure sufficient strength, it is necessary to use a large thickness of the board, which is heavy, takes up space, and is expensive. Moreover, the board contains a large amount of harmful substances such as formaldehyde, which seriously affects the health of users.

Utility model content

In view of this, the purpose of this utility model is to provide a novel structure of glass fiber reinforced formaldehyde-free plywood.

The utility model is realized by the following scheme: a glass fiber reinforced formaldehyde-free plywood, comprising wooden veneers on both sides and a middle core board between the two wooden veneers, the wood veneer and the middle core board are sandwiched A glass fiber layer is provided, and the glass fiber layer is glued between the middle core board and the wood veneer by a formaldehyde-free film-like thermoplastic wood adhesive.

Further, the intermediate core board is composed of multiple layers of wood veneers.

Further, a glass fiber layer is also sandwiched between two adjacent layers of wood veneers on the middle core board.

Further, the glass fiber layer has a grid structure, and the thickness of the glass fiber layer is 0.1-1mm.

Compared with the prior art, the utility model has the following beneficial effects: the glass fiber reinforced formaldehyde-free plywood can greatly increase the static bending strength and elastic modulus of the plywood, which can be increased to more than 50%, and the plywood can be properly reduced when used. Thickness, save wood, save space, reduce weight, and because glass fiber is a non-combustible inorganic substance, it can improve the flame retardancy of plywood; completely eliminate formaldehyde pollution, healthy and environmentally friendly, and has broad market prospects.

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail through specific embodiments and related drawings below.

detailed description

As shown in Figure 1, Embodiment 1 of the present utility model, a glass fiber reinforced formaldehyde-free plywood, comprises wooden veneers 1 on both sides and an intermediate core board 2 between the two wooden veneers 1, the wooden veneer A glass fiber layer 3 is sandwiched between 1 and the middle core board 2 , and the glass fiber layer 3 is glued between the middle core board 2 and the wood veneer 1 by the formaldehyde-free film-like thermoplastic wood adhesive 4 .

The glass fiber reinforced formaldehyde-free plywood can greatly increase the static bending strength and elastic modulus of the plywood, which can be increased to more than 50%, and the thickness of the plywood can be appropriately reduced during use, saving wood, saving space, and reducing weight. Fiber is a non-combustible inorganic substance, which can improve the flame retardancy of plywood; completely eliminate formaldehyde pollution, is healthy and environmentally friendly, and has broad market prospects.

In this embodiment, the glass fiber layer 3 has a grid structure, and the thickness of the glass fiber layer 3 is 0.1-1 mm.

Figure 2 shows Embodiment 2 of the present utility model. In this embodiment, the middle core board 2 is also composed of multi-layer wooden veneers, and between two adjacent wooden veneers is also a formaldehyde-free film-like thermoplastic wood. Adhesive 4 glues together.

As shown in Fig. 3 embodiment 3 of the present invention, in this embodiment, in order to obtain high-strength plywood, described intermediate core board 2 is made up of multi-layer wooden veneer, and between adjacent two layers of wooden veneer A glass fiber layer is also sandwiched, and the glass fiber layer 3 is also glued between adjacent wooden veneers on both sides by the formaldehyde-free film-like thermoplastic wood adhesive 4 .

The above preferred embodiments have further described the purpose, technical solutions and advantages of the utility model in detail. It should be understood that the above descriptions are only preferred embodiments of the utility model and are not intended to limit the utility model. For new models, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
