Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a can reduce multilayer plywood of formaldehyde emission volume, including medium plate 1, the top of medium plate 1 is equipped with roof 2, and the bottom of medium plate 1 is equipped with bottom plate 3, equal fixedly connected with a plurality of trapezoidal strip 7 on the bottom of roof 2 and the top of bottom plate 3, and the trapezoidal bearing groove 9 that cooperates a plurality of trapezoidal strip 7 to use is all seted up to the top of medium plate 1 and the bottom, the junction of roof 2 and medium plate 1 and the junction of bottom plate 3 and medium plate 1 all pass through big bean gum 6 fixed connection, 4 fixed connection are passed through bounding wall in the outside of roof 2 and medium plate 1 and bottom plate 3, it is concrete, glue can release the drawback of formaldehyde through white latex 5 and soybean gum 6 has been avoided, contain a large amount of formaldehyde in the glue in the tradition simultaneously, also contain formaldehyde in the panel, when carrying out the use of plywood, plywood in the tradition does not control formaldehyde, and then lead to leading to can release a large amount of formaldehyde, thereby make the problem of the security greatly reduced of plywood.

The scheme has the following working processes:

at first, utilize trapezoidal strip 7 and trapezoidal bearing groove 9 to dock, can carry out stable butt joint to centring plate 1 and roof 2 and bottom plate 3 to adopt white latex 5 and soybean to glue 6 adhesion material as panel, because white latex 5 glues 6 and is all non-aldehyde sizing materials with the soybean, so can not produce extra formaldehyde release except panel, utilize bounding wall 4 to wrap up all panels simultaneously, further avoided a large amount of releases of formaldehyde.

According to the working process, the following steps are known:

avoided glue can release the drawback of formaldehyde through white latex 5 and soybean glue 6, contained a large amount of formaldehyde in having avoided glue in the tradition simultaneously, contain formaldehyde in the panel equally simultaneously, when carrying out the use of plywood, plywood in the tradition does not control formaldehyde, and then leads to the plywood can release a large amount of formaldehyde to make the security greatly reduced's of plywood problem.

Further, the junctions of coaming 4 and roof 2 and medium plate 1, bottom plate 3 all pass through 5 fixed connection of white latex, and is concrete, utilizes coaming 4 to carry out the closure in the outside with roof 2 and medium plate 1, bottom plate 3, and then can further strengthen the effect of avoiding the formaldehyde release.

Further, the bottom of roof 2 all scribbles with the bottom of bottom plate 3 and is equipped with insulating layer 8, and is concrete, utilizes insulating layer 8 not only can make panel durable, carries out further isolation to formaldehyde simultaneously.

Further, the soybean glue 6 is a green and environment-friendly adhesive, and the soybean glue 6 is finally prepared by reacting soybean powder with other aqueous solvents and substances, namely, physically blending the soybean powder and the other aqueous solvents and substances, and does not contain any harmful substances such as formaldehyde, benzene and the like.

Furthermore, the white latex 5 is a thermoplastic adhesive prepared by vinyl acetate monomer through polymerization reaction under the action of an initiator, can be cured at normal temperature, is relatively fast in curing and relatively high in bonding strength, a bonding layer has relatively good toughness and durability and is not easy to age, and the white latex 5 is non-aldehyde glue and does not release formaldehyde.

Furthermore, the insulating layer 8 is made of a condensation waterproof material, so that the release of formaldehyde can be further insulated.

In summary, the enclosing plate 4 is used to seal the top plate 2, the middle plate 1 and the bottom plate 3 from the outside, so as to further enhance the effect of avoiding formaldehyde release, the isolation layer 8 is used to make the board durable, and further isolate formaldehyde, and the white latex 5 is non-aldehyde glue and does not release formaldehyde.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
