Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a synthetic solid wood board with no peculiar smell and antiseptic properties. Background Art

[0002] At present, the spliced ​​boards on the market are mainly composed of straight strips spliced ​​into boards. Since they usually adopt a single-layer structure, they are prone to deformation, cracking, shrinkage, discoloration and other problems in actual applications. In order to strengthen the structure, three-layer or two-layer spliced ​​boards have emerged, which have overcome the problems of single-layer structure to a certain extent. However, the product uses a large amount of raw materials and has a high cost.

[0003] As shown in the Chinese utility model patent with publication number CN 203418603 U, a new solid wood decorative board is disclosed, including a board core, which is a solid wood splicing board, and a layer of veneer is adhered to the upper and lower surfaces of the board core. The utility model uses veneer with a wood texture opposite to the splicing board to adhere to the solid wood splicing board, thereby strengthening the structure of the solid wood splicing board, thereby effectively avoiding problems such as cracking, deformation, and shrinkage. At the same time, it does not use a multi-layer splicing board structure, uses less raw materials, and has low cost.

[0004] Although the above patent solves the material and cost issues, the connection between the board core and the veneer layer is generally achieved through traditional glue, which is not safe and environmentally friendly. In addition, the board core is made of ordinary solid wood strips, which have poor anti-corrosion performance. Utility Model Content

[0005] The purpose of the utility model is to provide a synthetic solid wood board with a new structure and no odor and antiseptic properties, which can at least solve one of the above problems.

[0006] According to one aspect of the utility model, there is provided an odor-free and antiseptic synthetic solid wood board, comprising a substrate layer, and a transverse wood veneer layer and a decorative layer sequentially arranged on both end surfaces of the substrate layer from the inside to the outside;

[0007] The substrate layer is made of multiple deeply carbonized wood strips;

[0008] The grain of the horizontal wood cortex is perpendicular to the length extension direction of the deeply carbonized wood strips;

[0009] The cross-grained wood veneer layer is connected to the base material layer by an adhesive layer;

[0010] The adhesive layer is a negative ion titanium dioxide deodorizing adhesive film which is arranged between the transverse wood cortex layer and the base material layer or wrapped around the periphery of the transverse wood cortex layer.

[0011] Therefore, the utility model provides a synthetic solid wood board with a brand-new structure. The production process of the board is as follows: knots are removed from waste wood or fast-growing wood, and the teeth are connected into long strips, which are then placed in a wood carbonization tank for deep carbonization to obtain deep carbonized wood strips, which are planed on four sides, and then the planed deep carbonized wood strips are put together to form a large board to obtain a substrate layer, the substrate layer is sanded and leveled on both sides, and then a transverse wood veneer layer is attached to both sides of the flat and smooth substrate using a negative ion titanium dioxide odor-removing film instead of traditional glue by high-temperature hot pressing, and finally a decorative layer is hot-pressed on both sides.

[0012] The synthetic solid wood board of the utility model adopts deep carbonized wood strips as the base material layer, so that it has the excellent properties of carbonized wood, such as environmental protection, air purification, strong stability, not easy to crack and deform, corrosion resistance, long service life, and convenient processing; the texture of the transverse wood cortex layer is perpendicular to the length extension direction of the deep carbonized wood strips, thereby enhancing the strength of the board, thereby effectively avoiding the problems of cracking, deformation, shrinkage, etc.; the adhesive layer used is a negative ion titanium dioxide odor-removing film, which can not only replace traditional glue and is safe and environmentally friendly, but more importantly, the negative ions and titanium dioxide in the film can effectively remove the carbonized smell of the deep carbonized wood strips, so that the board can achieve the effect of basically no odor, improve the user's acceptance and improve the comfort of use.

[0013] In some embodiments, the decorative layer is an impregnated decorative paper, so that the combination can be achieved by hot pressing, which is simple to manufacture and has low production cost.

[0014] In some embodiments, the decorative layer is a negative ion impregnated decorative layer. Thus, the decorative layer contains negative ion powder, which will be firmly fixed on the surface of the plate under the action of heat pressing, will not fall off, will not cause environmental pollution, and is safe and environmentally friendly; because the negative ion powder is on the surface of the plate, it can directly contact with air and light, thereby increasing the negative ion content in the air, achieving the effect of purifying the air.

[0015] In some embodiments, the adhesive layer is a composite adhesive crystal material obtained by immersing the impregnated base paper into a composite adhesive solution containing negative ion powder and titanium dioxide powder, and is formed between the substrate layer and the transverse wood veneer layer under the action of heat pressing.

[0016] In some embodiments, the adhesive layer is a composite adhesive crystal material obtained by immersing the transverse wood cortex layer in a composite adhesive solution containing negative ion powder and titanium dioxide powder, and the composite adhesive crystal material includes a transverse wood cortex layer and an adhesive layer wrapped around the periphery of the transverse wood cortex layer. Therefore, compared with the solution of directly setting the adhesive layer between the substrate layer and the transverse wood cortex layer, this solution can not only omit the impregnation of base paper and save costs, but also has a better effect of removing odors, because: the adhesive layer on the upper end surface of the transverse wood cortex layer is more easily exposed to light, thereby allowing titanium dioxide and negative ions to fully play their role, achieving better air purification, sterilization and deodorization effects.

[0017] In some embodiments, the cross-grained veneer layer is a cross-grained veneer having a thickness of 0.2-0.6 mm.

[0018] In some embodiments, the thickness of the decorative layer is 0.1-2.0 mm.

[0019] In some embodiments, the thickness of the cross-grained wood cortex layer is 0.1-0.6 mm.

[0020] Beneficial effects of the utility model:

[0021] The synthetic solid wood board of the utility model adopts deep carbonized wood strips as the base material layer, so that it has the excellent properties of carbonized wood, such as environmental protection, air purification, strong stability, not easy to crack and deform, corrosion resistance, long service life, and convenient processing; the texture of the transverse wood cortex layer is perpendicular to the length extension direction of the deep carbonized wood strips, thereby enhancing the strength of the board, thereby effectively avoiding problems such as cracking, deformation, and shrinkage; the adhesive layer used is a negative ion titanium dioxide odor-removing film, which can not only replace traditional glue and is safe and environmentally friendly, but more importantly, the negative ions and titanium dioxide in the film can effectively remove the carbonized smell of the deep carbonized wood strips, so that the board achieves an effect of basically no odor, improves the user's acceptance and improves the comfort of use.

[0027] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1-2 As shown, the utility model provides a synthetic solid wood board without odor and antiseptic, comprising a substrate layer 1 and a transverse wood veneer layer 3 and a decorative layer 4 sequentially arranged on both end surfaces of the substrate layer 1 from the inside to the outside;

[0030] The substrate layer 1 is formed by splicing a plurality of deeply carbonized wood strips 11;

[0031] The grain of the transverse wood cortex layer 3 is perpendicular to the length extension direction of the deep carbonized wood strip 11;

[0032] The horizontal wood veneer layer 3 is connected to the base material layer 1 through the adhesive layer 2;

[0033] The adhesive layer 2 is a negative ion titanium dioxide deodorizing adhesive film disposed between the transverse wood veneer layer 3 and the base material layer 1 or wrapped around the periphery of the transverse wood veneer layer 3 .

[0034] Preferably, the decorative layer 4 is an impregnated decorative paper, so that the combination can be achieved by hot pressing, which is simple to manufacture and has low production cost.

[0035] The adhesive layer 2 is a composite adhesive crystal material obtained by immersing the impregnated base paper into a composite adhesive solution containing negative ion powder and titanium dioxide powder, and is formed between the substrate layer 1 and the transverse wood veneer layer 3 under the action of hot pressing. The specific preparation method and steps of the adhesive layer 2 refer to the Chinese invention patent with publication number CN105887558A.

[0036] Preferably, the transverse-grained veneer layer 3 is a transverse-grained veneer with a thickness of 0.2-0.6 mm.

[0037] Preferably, the thickness of the decorative layer 4 is 0.1-2.0 mm.

[0038] Preferably, the thickness of the transverse wood cortex layer 3 is 0.1-0.6 mm.

[0039] Therefore, the utility model provides a synthetic solid wood board with a brand-new structure, and the manufacturing process of the board is as follows: knots are removed from waste wood or fast-growing wood, and the teeth are connected into long strips, which are then placed in a wood carbonization tank for deep carbonization to obtain deep carbonized wood strips 11, the deep carbonized wood strips 11 are planed on four sides, and then the planed deep carbonized wood strips 11 are assembled together into a large board to obtain a substrate layer 1, the substrate layer 1 is double-sided sanded and leveled, and then a transverse wood veneer layer 3 is attached to both sides of the flat and smooth substrate using a negative ion titanium dioxide deodorizing film instead of traditional glue by high-temperature hot pressing, and finally a decorative layer 4 is hot-pressed on both sides.

[0040] The synthetic solid wood board of the utility model adopts deeply carbonized wood strips 11 as the base material layer 1, so that it has the excellent properties of carbonized wood, such as environmental protection, air purification, strong stability, not easy to crack and deform, corrosion resistance, long service life, and convenient processing; the texture of the transverse wood veneer layer 3 is perpendicular to the length extension direction of the deeply carbonized wood strips 11, which strengthens the strength of the board, thereby effectively avoiding problems such as cracking, deformation, and shrinkage; the adhesive layer 2 used is a negative ion titanium dioxide odor-removing film, which can not only replace traditional glue and is safe and environmentally friendly, but more importantly, the negative ions and titanium dioxide in the film can effectively remove the carbonized smell of the deeply carbonized wood strips 11, so that the board can achieve the effect of basically no odor, improve the user's acceptance and improve the comfort of use.

[0041] Example 2

[0042] like Figure 3 As shown, the utility model provides another embodiment of an odor-free and antiseptic synthetic solid wood board, the structure of which is basically the same as that of the synthetic solid wood board of Example 1, except that the adhesive layer 2 of this embodiment is formed in a different way.

[0043] In this embodiment, the adhesive layer 2 is a composite adhesive crystal material obtained by immersing the transverse wood cortex layer 3 in a composite adhesive solution containing negative ion powder and titanium dioxide powder. The composite adhesive crystal material includes the transverse wood cortex layer 3 and the adhesive layer 2 wrapped around the periphery of the transverse wood cortex layer 3. Under the action of hot pressing, the transverse wood cortex layer 3 is connected to the substrate layer 1 through the adhesive layer 2. Therefore, compared with the solution of directly setting the adhesive layer 2 between the substrate layer 1 and the transverse wood cortex layer 3, this solution can not only omit the impregnation of base paper and save costs, but also has a better effect of removing odors. The reason is that the adhesive layer 2 on the upper end surface of the transverse wood cortex layer 3 is more easily exposed to light, thereby allowing titanium dioxide and negative ions to fully play their role, achieving better air purification, sterilization and deodorization effects.

[0044] Example 3

[0045] like Figure 4As shown, the utility model provides another embodiment of an odor-free and antiseptic synthetic solid wood board, the structure of which is substantially the same as that of the synthetic solid wood board of Example 1, except that the decorative layer 4 of this embodiment is different.

[0046] In this embodiment, the decorative layer 4 is a negative ion impregnated decorative layer 4. The specific preparation principle and process are as follows: S1, processing of raw materials: add 20-50% of transparent water-soluble negative ion powder to a grinder and grind it finely, sieve to obtain 300-500 mesh negative ion powder, and set aside. S2, preparation of negative ion concentrated solution: add the negative ion powder obtained in S1 to a stirring container, then add 30-70% of distilled water and mix evenly, then add 5-15% of water-soluble transparent resin glue and mix evenly, finally add 2-8% of volatile auxiliary agent, stir evenly until it is a clear liquid, and seal it for use. In this process, adding distilled water can dissolve the negative ion powder; adding water-soluble transparent resin glue to mix can increase the density of the mixed solution, and at the same time prevent the negative ion powder from precipitating at the bottom of the container, so that the negative ion powder is evenly dispersed in the mixed solution; sealing after adding the volatile auxiliary agent can effectively prevent the volatile auxiliary agent from volatilizing and failing. S3, preparation of decorative paper: firstly, dip the impregnated paper into glue, wait until the surface of the impregnated paper is dry, then roll the anion concentrate prepared in S2 onto the surface of the impregnated paper by a roll coating device or spray the anion concentrate onto the surface of the impregnated paper by a spray coating device, so that a thin anion layer is formed on the surface of the impregnated paper, and then the impregnated paper is placed in a drying device and dried until the water is completely evaporated, and the remaining anion crystals are evenly bonded to the surface of the impregnated paper, so as to obtain anion impregnated decorative paper. For other detailed processes, refer to the Chinese invention patent with application publication number CN 109235133 A.

[0047] Therefore, the decorative layer 4 contains negative ion powder. Under the action of hot pressing, the negative ion powder will be firmly fixed on the surface of the board and will not fall off, causing no environmental pollution, which is safe and environmentally friendly. Since the negative ion powder is located on the surface of the board, it can directly contact with air and light, thereby increasing the negative ion content in the air and achieving the effect of purifying the air.

[0048] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
