A kind of have ultralow core-board and a glued board of releasing aldehyde
Technical field
The present invention is a kind of to have ultralow core-board and the glued board of releasing aldehyde, belongs to furniture and house ornamentation section bar field.
Background technology
As everyone knows, joiner sheet material, usually by central layer, middle plate, the multi-layer sheet such as panel form by the tack coat bonding, tack coat between the adjacent laminate normally contains the tack coat of the organic binder bond formation of formaldehyde, glued board is similar to joinery board structure, formed by the tack coat bonding by plate in the multilayer and panel, because core-board, glued board is widely used in furniture, house ornamentation and indoor packing container, the formaldehyde of its volatilization will cause certain pollution to indoor environment for use, according to China core-board standard GB/T/T5849-2006 and National Standards for Plywood GB/T 9846.1-2004, indoor core-board, its formaldehyde of glued board discharges Limited Doses and is divided into E 0, E 1, E 2Three grades, E 0, E 1The Limited Doses of level, by the every unit of being upgraded to of milligram, be respectively≤0.5mg/l ,≤1.5mg/l, reach E 0, E 1Other core-board of level, glued board can be directly used in indoor.With prior art general contain core-board, the glued board that the formaldehyde organic binder bond is bondd and produces, generally can satisfy national standard E 1The level requirement; but; in order to adapt to the requirement of national sustainable economic development and environmental protection; satisfy the consumer to the demand of high-quality environment-friendly products; exploitation furniture and house ornamentation field be ultralow core-board, the plywood product of releasing aldehyde of high-quality more; extremely manufacturing enterprise and consumer's concern is very urgent.
Summary of the invention
The purpose of this invention is to provide a kind of ultralow core-board and glued board of releasing aldehyde that have, to guarantee for indoor core-board and the glued board E that is up to state standards 0Level is released the good value requirement of aldehyde, favorable environment protection and health.
The objective of the invention is to be achieved through the following technical solutions:
One, the present invention is a kind of has a ultralow core-board of releasing aldehyde, formed by panel, middle plate, center central layer and relevant connection interface tack coat, be connected with middle plate, panel successively respectively by tack coat from central layer two sides, center, characteristics are that the tack coat of described central layer two sides, relevant center and middle plate linkage interface, middle plate and panel linkage interface is the suction aldehyde tack coat that contains negative ion powder, and there is the formaldehyde scavenger coating on the surface outside the described panel.
The negative ion powder that contains of central layer two sides, described center and middle plate linkage interface is inhaled the aldehyde tack coat, by mass percentage, its Lauxite is 75%, negative ion powder be 20% and cellulose be 5%.
The negative ion powder that contains of described middle plate and panel linkage interface is inhaled the aldehyde tack coat, by mass percentage, its Lauxite is 75%, negative ion powder is 20%, cellulose be 3% and formaldehyde scavenger be 2%.
Between described center central layer and the middle plate functional laminate is set.
Two, the present invention is a kind of has a ultralow glued board of releasing aldehyde, by panel, middle plate, in plate and relevant connection interface tack coat form in the heart, from in the heart the plate two sides be connected with middle plate, panel successively respectively by tack coat, characteristics be described relevant in the heart the tack coat of plate two sides and middle plate linkage interface, middle plate and panel linkage interface be the suction aldehyde tack coat that contains negative ion powder, there is the formaldehyde scavenger coating on the surface outside the described panel.
In described in the heart the negative ion powder that contains of plate two sides and middle plate linkage interface inhale the aldehyde tack coat, by mass percentage, its Lauxite is 75%, negative ion powder be 20% and cellulose be 5%.
The negative ion powder that contains of described middle plate and panel linkage interface is inhaled the aldehyde tack coat, by mass percentage, its Lauxite is 75%, negative ion powder is 20%, cellulose be 3% and formaldehyde scavenger be 2%.
The present invention is a kind of to have ultralow core-board and the glued board of releasing aldehyde, creatively adopt the tack coat that contains negative ion powder at each adjacent laminate linkage interface, given full play to the effect of the pernicious gases such as lasting absorption formaldehyde of negative ion powder, and inhale to replenish in the aldehyde tack coat and added the formaldehyde scavenger composition at the negative ion powder that contains of middle plate and panel linkage interface, the formaldehyde scavenger coating has been executed on the surface outside described panel, therefore, make the present invention bond laminate from inside to outside, set up defenses in depth, effectively absorb and suppressed the release of the harmful formaldehyde gas of organic coating, check shows, the burst size of methanal of two products of the present invention is 0.2mg/l, is starkly lower than the E of these two products 0The higher limit of level≤0.5mg/l, product of the present invention have not only satisfied standard GB/T/T5849-2006 and standard GB/T/T 9846.1-2004, and indoor core-board and glued board formaldehyde are discharged the E that limits the quantity of 0Level≤0.5mg/l requirement, and reach good value level, given the ultralow aldehyde environmental protection effect of product fine, significantly promoted the inherent quality of product, greatly favorable environment protection and health.
