Description

A kind of immersion-resistant and flame-retardant plywood

technical field

The utility model relates to the technical field of soaking-resistant and flame-retardant plywood, in particular to a soaking-resistant and flame-retardant plywood.

Background technique

With the development of my country's social economy, the practical demand of wood-based panels in construction engineering, interior decoration, home manufacturing, packaging and other industries is increasing. However, the raw materials of wood-based panels are mostly plant fibers, which are combustible materials. The flammability of wood-based panels is An important cause of fires. In recent years, fire accidents in my country are on the rise, and the losses caused by fires are becoming more and more serious. Therefore, plywood with flame retardant properties has attracted more and more attention. Of course, immersion resistance is also important for plywood, because now If the plywood is soaked in water, it will become moldy, affect the appearance, and may delaminate. At present, most of the flame-retardant plywood is to impregnate the veneer or the finished product, which brings a lot of trouble to the actual production. Therefore, we propose a durable Soaked and flame-retardant plywood is used to solve the above problems.

Utility model content

The purpose of this utility model is to provide a soaking-resistant and flame-retardant plywood to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions: a soaking-resistant and flame-retardant plywood, including a plywood body, the plywood body is composed of a substrate and a bamboo fiber board, the bottom of the plywood body is provided with a substrate, and the substrate is connected by adhesive glue. Bamboo fiberboard, the surface of the bamboo fiberboard is bonded with a flame-retardant woven mesh, and the bamboo fiberboard is fixed with a horizontal fixing plate and a vertical fixing plate through expansion screws. The horizontal fixing plate and the vertical fixing plate form a cavity, and a dry powder is installed in the cavity granules, and the bamboo fiber board at the upper end of the dry powder granules is fixed on the horizontal and vertical fixing plates by adhesive glue, and the joints of the horizontal and vertical fixing plates and the upper bamboo fiber board are provided with a steel fiber mesh through the adhesive glue. The upper layer of the bamboo fiberboard is brushed with an anti-soaking coating.

Preferably, for a soaking-resistant and flame-retardant plywood, expansion screws are arranged at the cross intersections of the horizontal fixing plate and the longitudinal fixing plate, and the expansion screws fasten and connect the upper and lower layers of bamboo fiber boards.

Preferably, the thickness of the bamboo fiber board is 3mm, and the anti-soaking coating on the bamboo fiber board is polyester glue.

Preferably, the meshes in the flame-retardant woven mesh and the steel fiber mesh are 0.25*0.25 rhombus meshes.

Compared with the prior art, the beneficial effect of the utility model is: the structure of the utility model sets the plywood body as a bamboo fiber board, which can make it have flame retardancy. When a fire occurs and the fire has burned the upper plywood, the Setting dry powder particles in the cavity formed by the horizontal fixing plate and the vertical fixing plate can make the dry powder particles chemically react with the flame to extinguish the flame. By setting a flame-retardant woven mesh on the plywood body, the flame retardancy of the plywood is further improved. High reliability, by tightly connecting the upper and lower layers of bamboo fiber boards with expansion screws, the upper and lower layers of bamboo fiber boards will not be easily delaminated when soaked in water, and the bamboo fiber boards are brushed with anti-soaking coating, which can maximize the anti-soaking of the plywood body The connection between the upper bamboo fiber board and the cavity is provided with a steel fiber mesh, which can increase the overall strength of the plywood body. Through these several methods, the immersion resistance and flame retardancy of the plywood in the prior art are well improved.
