Problems solved by technology

In the prior art, the raw materials used to make the tatami core layer are generally derived from natural materials such as wood fiber materials or paper, which consume a lot of natural resources and are costly
Moreover, this kind of material is easy to absorb moisture, and it will deform after absorbing moisture, resulting in a decrease in the strength of the board, and it is easy to mold and be eaten by insects.
Therefore, tatami mats made of such materials are not suitable for use in areas with humid climates

Embodiment 1

[0020] Figure 1 is a front view of tatami mats.

[0021] As shown in FIG. 2, the tatami mat implemented according to the present invention includes a core layer 2 located in the middle, a stacking table 1 located on the upper surface, and a non-slip cloth 5 located on the lower surface. Wherein, the material of the core layer 2 is a wheat straw board, and the wheat straw board is made by bonding and shaping crushed rice and wheat straw with an isocyanate resin adhesive.

[0022] The folding table 1 covers the entire upper surface of the tatami, and wraps the four sides of the tatami, extends to the bottom of the tatami, and is folded inward. The non-slip mat 5 completely covers the lower surface of the core layer 2 and the outer surface of the folded part of the folded table 1 on the bottom of the tatami mat. The function of the anti-slip mat 5 is to prevent sliding between the tatami and the ground or the table top.

[0023] All the above-mentioned structural layers of the tatami...

Embodiment 2

[0025] As shown in FIG. 3, the difference between this embodiment and Embodiment 1 is only that an elastic layer 3 is further provided between the laminated watch and the core layer 2.

[0026] The elastic layer 3 is made of a plurality of polyurethane foam plastic particles with an open-cell structure, which are mixed with the raw material monomers of the polyurethane foam after stirring and uniformly stirred, and then subjected to secondary foaming, and then formed through a forming process and a cutting process. Its function is to increase the comfort of the human body in contact with the tatami.

[0027] The elastic layer 3 can also be made of polyethylene foam plastic particles.

Embodiment 3

[0029] As shown in FIG. 4, the difference between this embodiment and Embodiment 1 is only:

[0030] A bottom lining 4 is also provided between the core layer 2 and the anti-slip cloth 5. The area of ​​the backing 4 is slightly smaller than that of the tatami, and its edge is in contact with the edge of the folded table 1 that is folded inward. The non-slip mat 5 completely covers the lower surface of the bottom lining 4 and the outer surface of the folded part of the folded table 1 on the bottom of the tatami mat.

[0031] The material used to make the bottom liner 4 can be the same as the material used to make the elastic layer 3, that is, polyurethane foam or polyethylene foam.

Abstract

The invention relates to a tatami, which comprises a core layer arranged at the middle part, a folding surface arranged on the upper surface, a piece of anti-skid cloth arranged on the lower surface, a bottom liner arranged between the core layer and the anti-skid cloth, and an elastic layer arranged between the core layer and the folding surface. The core layer is of a wheat straw plate. The wheat straw plate comprises pulverized paddy straw and wheat straw adhered by isocyanate pitch adhesive and then molded. The tatami performed according to the invention has the advantages of low production cost, environmental protection, and no harm to the human body. The straw plate is uneasy to be wetted, therefore, the distortion is unable to produce, and the straw plate is mildew proof and vermin proof. The straw plate has higher strength and weight ratio, thereby the tatami performed according to the invention has light weight, high strength, and no extra reinforced layer is needed.

Description

Technical field [0001] The present invention relates to a tatami. Background technique [0002] The main components of tatami mats include a core layer located in the middle, a stack surface attached to the upper surface of the core layer, and a bottom lining attached to the lower surface of the core layer. In the prior art, the raw materials used to make the tatami core layer are generally derived from natural materials such as wood fiber materials or paper, which consume a large amount of natural resources and are relatively expensive. Moreover, this kind of material is easy to absorb moisture, and it will deform after absorbing moisture, which will cause the strength of the board to decrease, and it is easy to mold and be eaten by insects. Therefore, tatami mats produced with such materials are not suitable for use in humid climates. [0003] Wheat straw board is a kind of man-made composite board with excellent performance made from agricultural production residue-wheat straw...
