Pavement equipment for functional shaving boards with multilayered structures and production method realized by aid of equipment

Abstract

The invention relates to pavement equipment for functional shaving boards with multilayered structures. The pavement equipment comprises a pavement belt (1), a lower-surface-layer shaving pavement head (2), at least one layer of core-layer shaving pavement head (3) and an upper-surface-layer shaving pavement head (4). The lower-surface-layer shaving pavement head (2), the core-layer shaving pavement heads (3) and the upper-surface-layer shaving pavement head (4) are sequentially mounted at different front-back positions of the upper side of the pavement belt (1). The pavement equipment is characterized in that at least one functional material pavement head (5) is disposed between the lower-surface-layer shaving pavement head (2) and the upper-surface-layer shaving pavement head (4). The invention further relates to a production method realized by the aid of the equipment. The production method includes steps of a, running the pavement belt; b, uniformly discharging materials by the various pavement heads; c, forming a board blank by means of pre-pressing by the aid of a pre-pressing roll (20); d, realizing hot-press forming; and e, realizing trimming and sanding and forming a finished product. A multilayered-structured functional shaving board produced by the aid of the equipment and the production method has excellent physical and mechanical performances, and is fine in applicability and functionality and low in cost.

Description

technical field [0001] The invention relates to a multi-layer structure functional particle board paving equipment and a production method using the equipment. [0002] Background technique [0003] With the improvement of living standards, people put forward higher and higher requirements for the functionality of particleboard, such as requiring particleboard to have flame retardancy, moisture resistance, sound insulation, antistatic and antibacterial properties. At present, the production of functional particleboard is generally divided into two ways, one is to use particleboard and functional board to glue together in a certain way, the other is to add functional materials to the raw material of particleboard in the production process and then pave , Hot pressing. However, the former kind of functional particleboard made of gluing, because it is not formed by one-time hot pressing, makes the production cost increase, the bonding strength between the board layers is poor...

Problems solved by technology

However, the former kind of functional particleboard made of gluing, because it is not formed by one-time hot pressing, makes the production cost increase, the bonding strength between the board layers is poor, the physical and mechanical properties are low, and the glue layer is easily produced due to the influence of the environment. Aging causes problems such as structural debonding

The functional particleboard produced by the latter method is made by adding functional materials to the particleboard raw materials and then paving and hot pressing. In this case, if you want to produce functional particleboard Adding corresponding functional materials to the board, due to the large amount of particle board raw materials, in order to achieve the functional effect of the particle board, it is often necessary to add a large amount of functional materials, adding a large amount of functional materials will affect the physical and mechanical properties of the particle board, and at the same time, the functional The cost of materials is usually much higher than that of wood shavings, which increases the production cost, and the mixed method of functional materials and wood shavings is not ideal for its functional effects, such as fire prevention, anti-static, and radiation protection. It is often necessary to form a continuous Compartments can perform their functions optimally
