Radiation-resistant fiber board and production method thereof

Abstract

The invention relates to a radiation-resistant fiber board, which comprises a lower surface fiber layer 1 and an upper surface fiber layer 2. A radiation-resistant metal layer 3 is arranged between the lower surface fiber layer 1 and the upper surface fiber layer 2, and mixed metal powder and adhesive materials are paved to form the radiation-resistant metal layer 3. The invention further relates to a production method of the radiation-resistant fiber board. The production method is characterized by comprising steps of a, running paving equipment and running a paving belt (5); b, uniformly feeding paving heads of various layers at different front and back positions of the paving belt; c, forming a board blank by means of pre-compaction by the aid of a pre-compaction roll (6); d, realizing hot pressing forming; and e, realizing trimming and sanding and forming a finished product. The radiation-resistant fiber board produced by the aid of the production method is fine in radiation-resistant effect, simple in production process and fine in physical and mechanical performances.

Description

[0001] technical field [0002] The invention belongs to the technical field of fiberboard production, and in particular relates to a fiberboard with good radiation protection effect and a production method thereof. [0003] Background technique [0004] With the expansion of the application field, people put forward higher and higher requirements for the functionality of some areas, such as the requirement of radiation protection. At present, because the decorative panels do not have this function, the realization of this function usually needs to be installed separately in the building. shielding layer, installation is complex and very costly. For this reason, the industry has designed a particleboard with anti-radiation function. For example, the name disclosed in the Chinese utility model patent is "anti-radiation particleboard" (patent number: 201120179950.7). Composite with the backboard, there is a radiation-proof wire mesh between the panel and the core board. The ...

[0004] With the expansion of the application field, people put forward higher and higher requirements for the functionality of some areas, such as the requirement of radiation protection. At present, because the decorative panels do not have this function, the realization of this function usually needs to be installed separately in the building. Shielding, complex and very costly to install

For this reason, the industry has designed a particleboard with anti-radiation function. For example, the name disclosed in the Chinese utility model patent is "anti-radiation particleboard" (patent number: 201120179950.7). Composite with the backboard, there is a radiation-proof wire mesh between the panel and the core board. The radiation-proof particleboard using this technology can play a certain radiation-proof function, but because the wire mesh is used, the wire mesh There are gaps between them, so it cannot play a complete role in radiation protection, and the radiation-proof particleboard with wire mesh structure cannot be fully automatic produced on the particleboard paving equipment. It is necessary to manufacture each layer of particleboard first, and then between layers. Bonding, the radiation-proof particleboard manufactured by this production process, because the layers are bonded by the later bonding process, the physical and mechanical properties are poor, and the wire mesh is designed with an asymmetric structure, the particleboard expands with heat and contracts with cold. under the influence of
