Detailed Description
The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
Example (b): as shown in fig. 1, 2, 3, 4, 5 and 6, the solid wood composite floor with the high wear-resistant resin impregnated paper veneer comprises a solid wood substrate 3, a wear-resistant decorative layer 1 arranged on the upper surface of the solid wood substrate 3, and a balance moisture-proof layer 2 arranged on the lower surface of the solid wood substrate 3.
In this embodiment, the solid wood substrate 3 is made of oak and canadian pine according to the prior art, and the wear-resistant decorative layer 1 and the balance moisture-proof layer 2 are formed by impregnating the wear-resistant decorative layer 1 with resin on both sides, then allowing the balance moisture-proof layer 2 to be attached with resin, and finally peeling off, so that the balance moisture-proof layer 2 can be left with a proper amount of the required resin, which has the advantages that: firstly, the whole production process is simple, and no extra resin is coated on the balance moisture-proof layer 2; the resin components at the second position and the second position are the same, and the dosage can be different, so that the structural and performance uniformity of each layer of the solid wood composite floor can be further ensured; thirdly, the amount of the resin required to be left on the balance moisture-proof layer 2 is flexible and adjustable.
The wear-resistant decorative layer 1 sequentially comprises wear-resistant paper 101, a composite bonding layer 102, decorative paper 103 and a first bonding layer 104 from top to bottom. The composite bonding layer 102 is provided with reinforcing fibers 102a arranged in the transverse direction for increasing the transverse tensile strength of the wear-resistant decorative layer 1. The reinforcing fibers 102a are suspended by the middle weight 102b to maintain the U-shaped laterally aligned configuration.
In the present embodiment, the tie layer 102 and the first adhesive layer 104 are both formed by impregnating resin, but the initial thickness of the two layers can be selected by adjusting the impregnation angle of the decorative paper 103, which is very flexible, wherein the thickness of the tie layer 102 is set to 1.5-2.1mm, and the thickness of the first adhesive layer 104 is set to 1.2-1.6mm, so as to ensure that the reinforcing fibers 102a have enough accommodation space.
In addition, after the wear-resistant decorative layer 1 is pressed, the composite bonding layer 102 is the main object of deformation under pressure, the transverse tensile capacity of the composite bonding layer 102 is far from enough if the composite bonding layer 102 is formed by a single resin, and the composite bonding layer 102 has the problems of collapse and fracture after being used for 1-2 years, so that the reinforcing fibers 102a are required to be introduced to reinforce the transverse tensile capacity of the composite bonding layer 102 and avoid that the composite bonding layer 102 is relatively easily crushed.
The material of the reinforcing fiber 102a is organic polypropylene fiber or nylon fiber, inorganic glass fiber or carbon fiber, so as to ensure that the stress can be transmitted inside the composite bonding layer 102, thereby avoiding the problem that the composite bonding layer 102 is easy to collapse locally due to local concentrated stress, and the length of the reinforcing fiber 102a is 3.0-5.0 cm.
Finally, the middle weight 102b is integrally formed with the reinforcing fibers 102a, and is essentially only a middle bulge, so as to ensure that the reinforcing fibers 102a can be in a U-shaped form and transversely located in the composite adhesive layer 102, thereby preventing the reinforcing fibers 102a from being too vertical, otherwise the effect of improving the transverse tensile strength is greatly reduced.
The balance moisture-proof layer 2 comprises a second bonding layer 201 and a composite kraft paper 202 from top to bottom in sequence. The composite kraft paper 202 includes a kraft paper main body 202a, a mesh cloth 202b provided on an upper surface of the kraft paper main body 202a and used for attaching a bonding resin, and bonding bars 202c provided at both side positions on the upper surface of the kraft paper main body 202a, respectively, and used for pre-bonding the mesh cloth 202 b.
In this embodiment, the balancing moisture barrier 2 requires a "snatching" of the partially impregnated resin from the decorative paper 103, and thus if existing, single kraft paper is used for the balancing moisture barrier 2, the amount of resin remaining thereon is limited and cannot be used at all to firmly bond the solid wood substrate 3.
Therefore, the mesh cloth 202b is fixed to the kraft paper body 202a by the adhesive strips 202c on both sides in advance, so that a relatively large amount of the impregnating resin is trapped on the mesh cloth 202b, eventually ensuring that the second adhesive layer 201 has a sufficient and appropriate thickness.
The composite adhesive layer 102, the first adhesive layer 104, the second adhesive layer 201, and the adhesive strip 202c are all made of the same resin.
In this embodiment, the impregnating resin is any one of an amino resin, an epoxy resin, or a phenol resin.
Before the wear-resistant paper 101 and the composite kraft paper 202 are prepared into the solid wood composite floor, one side surface of the wear-resistant paper and the composite kraft paper is provided with a protective film 14.
In this embodiment, the protective film 14 is a conventional transparent plastic film, and has two functions: firstly, the wear-resistant paper 101 and the composite kraft paper 202 are used for protecting in the initial process, namely the storage and transportation process; secondly, when the wear-resistant decorative layer 1 and the balance moisture-proof layer 2 are pressed and peeled, the protective film 14 is wound by a driving roller to be used as a power source for the forward movement of the wear-resistant decorative layer 1 and the balance moisture-proof layer 2.
A method for producing a solid wood composite floor with a high-wear-resistance resin impregnated paper veneer sequentially comprises the following steps:
s1, impregnating resin on two sides of the decorative paper 103 to obtain a decorative layer precursor 11;
s2, spraying the reinforcing fibers 102a onto one surface of the decorative layer precursor 11 to obtain a decorative layer substrate 12;
s3, pressing the wear-resistant paper 101 and the composite kraft paper 202 on two sides of the decorative layer substrate 12 respectively, and tearing off the protective film 14 to obtain a composite layer 13;
s4, peeling the composite kraft paper 202 from the composite layer 13 to obtain the final wear-resistant decorative layer 1 and the final balance moisture-proof layer 2.
In S3, the wear-resistant paper 101 and the composite kraft paper 202 are pressed simultaneously; in S4, peeling off the composite layer 13 with a stainless steel knife having a thickness of 0.03-0.2mm, wherein an acute angle a between the wear-resistant decorative layer 1 and the composite layer 13 is 15-22 °, and an acute angle b between the balance moisture-proof layer 2 and the composite layer 13 is 45-48 °.
In this embodiment, the decorative paper 103 is impregnated with resin by means of an immersion roll winding, and the reinforcing fibers 102a are blown by means of an open-cell box blower, ensuring that the addition of blowing on the decorative layer precursor 11 can be carried out as desired.
In addition, the pressing pressure of the wear-resistant paper 101 and the composite kraft paper 202 is 50-400N/cm, and the thickness of the second bonding layer 201 obtained by peeling the wear-resistant paper 101 and the composite kraft paper 202 is 1.4-1.8mm, so that the composite kraft paper 202 can stably bond the solid wood substrate 3, and then the gridding cloth 202b is also in the area of 1.4-1.8 mm.
Finally, the wear-resistant decorative layer 1 and the balance moisture-proof layer 2 are respectively drawn and discharged at different angles, so that the 'holding capacity' of the impregnating resin on each layer can be adjusted, and the impregnating resin at the composite bonding layer 102 cannot be taken away by the balance moisture-proof layer 2.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
