Abstract
The utility model relates to a free formaldehyde capture agent used for wooden man-made board, especially to a micro-capsule product to capture free formaldehyde used in urea aldehyde resin glue particle board, medium density fiber board, plywood, and joinery board. The utility model comprises a macromolecular compound capsule coat and a free formaldehyde capture agent capsule core arranged therein. During the production procedure of the wooden man-made board, the releasing amount of free formaldehyde of the man-made board can be reduced by adding the micro-capsular product during glue sizing or spreading, thus environmental pollution is reduced.
Description
The utility model relates to the catching agent for free formaldehyde that a kind of wood-base fibre and particle panel material is used, and especially refers to the seizure free formaldehyde microcapsule product that urea-formaldehyde resin adhesive shaving board, medium density fibre board (MDF), glued board, core-board are used.
At present, the tackiness agent of the glued board of shaving board, medium density fibre board (MDF), indoor use, core-board use mainly is a urea-formaldehyde resin adhesive.Urea-formaldehyde resin adhesive is generated by urea and formaldehyde reaction.Contain a small amount of unreacted formaldehyde in the urea-formaldehyde resin adhesive, exist with unbound state.Though, in building-up process, reduce the mol ratio of formaldehyde and urea as far as possible.The mol ratio of formaldehyde and urea is low more, and free formaldehyde content is few more, but the mol ratio of formaldehyde and urea less than 1.2: 1 o'clock, the bonding strength of tackiness agent is relatively poor, package stability is relatively poor, storage period is shorter.Therefore the mol ratio of formaldehyde and urea can not unrestrictedly reduce.Therefore still have a spot of free formaldehyde to exist in the urea-formaldehyde resin adhesive, and in making the wood-based plate process, also can emit free formaldehyde during the urea-formaldehyde resin adhesive curing reaction.Free formaldehyde is present in the wood-based plate, can discharge gradually in wood-based plate uses.
At present, the glued board of shaving board, medium density fibre board (MDF), indoor use, core-board are mainly used in and make furniture and interior decoration.In the use of room, these wood-based plates can discharge free formaldehyde gradually, contaminate environment, infringement HUMAN HEALTH.
In view of this, the purpose of this utility model provides the seizure free formaldehyde microcapsule product that a kind of shaving board, medium density fibre board (MDF), glued board, core-board are used.Utilize the macromolecular compound capsule shell, comprise material, form microcapsule product with the effect of seizure free formaldehyde.
In the wood-based plate manufacturing processed, directly this microcapsule product is added in the urea-formaldehyde resin adhesive, manufacturing process by general wood-based plate is carried out applying glue or gluing, carry out hot pressing after mating formation into slab, microcapsules rupture when hot pressing, catching agent for free formaldehyde just with tackiness agent in free formaldehyde reaction, thereby reduce the free formaldehyde release of wood-based plate.
The purpose of this utility model is achieved in that the glued board of shaving board, medium density fibre board (MDF), indoor use, the seizure free formaldehyde microcapsule product that core-board is used, and its constitutional features is to be made of macromolecular compound capsule shell and interior catching agent for free formaldehyde capsule-core thereof.Described macromolecular compound capsule shell is the soft shell body of being made by polyvinyl alcohol or gelatin.Described catching agent for free formaldehyde is organic amine compound, ammonium salt or amino acid.Described macromolecular compound capsule shell is sphere or round bar shape.
In the wood-based plate manufacturing processed, directly the microcapsule product that adopts such scheme to form is added in the urea-formaldehyde resin adhesive, carry out applying glue or gluing by the manufacturing process of general wood-based plate, carry out hot pressing after mating formation into slab.Microcapsules rupture when hot pressing, thus catching agent for free formaldehyde just with tackiness agent in free formaldehyde reaction reduce the free formaldehyde release of wood-based plate.The wood-based panel product of making is checked burst size of methanal≤8mg formaldehyde/100g plate (level that is equivalent to European standard E1 level) by national standard
