Description

Environment-friendly plywood with good aging resistance

Technical Field

The utility model relates to an environment-friendly plywood technical field especially relates to an environment-friendly plywood that ageing resistance is good.

Background

The urea-formaldehyde resin adhesive is one of the high molecular adhesives which are developed and applied earlier, is widely used for manufacturing various artificial boards in the wood industry, accounts for more than 90 percent of the glue consumption of the artificial boards, accounts for more than 60 percent of the total consumption of the adhesives in the wood processing industry, and is the variety with the largest consumption in the adhesives. It can be used in large quantities because it has many advantages: if the price is low, the raw material source is rich, and the price is the lowest in the synthetic resin; has good gluing performance, higher cold water resistance and medium hot water resistance: the color of the cured glue layer is light, and the color of the surface of the plywood cannot be influenced. In addition, the water solubility is better, and the proper viscosity is easy to prepare.

In recent years, forest resource protection projects in China are started, and traditional wood export countries also have more and more wood export restrictions in succession, so that structural changes occur in wood for the wood industry, and the production of the plywood is changed from the prior art of adopting large-diameter logs to the technology of adopting fast-growing artificial forest wood (such as poplar wood and the like). In order to improve the production rate of the plywood, a method for increasing the number of layers of a multilayer hot press is generally adopted at home and abroad, a process without a base plate is adopted in a limited vertical space, the relative distance between pressing plates is reduced to the greatest extent so as to reduce the closing time of the press, and therefore, the plate blank needs to be subjected to cold pressing and preliminary forming before entering the press, and then is subjected to hot pressing. In addition, the mechanization and automation degree of many domestic plywood factories is not high, the urea-formaldehyde resin adhesive with poor slab prepressing initial viscosity performance is limited in production due to frequent movement and turning in process connection, and especially the requirement on slab prepressing strength is higher by a secondary gluing production process and a four-layer plywood structure production process with a symmetrical structure which appear in recent years.

Along with people's health consciousness, the improvement of indoor environment consciousness and quality of life consciousness, people are more and more paying attention to the release of urea-formaldehyde resin glue formaldehyde in the use, but present a large amount of plate fitment are mostly installed by the plywood and are formed, current plywood formaldehyde content is too high, the air direct emission that contains formaldehyde is with aerial, cause the pollution to the air easily, formaldehyde enters into in the respiratory track simultaneously, harm people's healthy, and current plywood stabilizes the fastness poor, and the service life is reduced, therefore, we have provided an environmental protection type plywood that ageing resistance is good and have solved above-mentioned problem.
