Description
Technical Field
The invention belongs to the technical field of decorative materials, and particularly relates to a hot-melt paint decorative panel and a preparation method and application thereof.
Background
The current process route of the traditional melamine veneer comprises two steps: 1. adhering melamine paper on the surface of the base material; 2. the surface of the melamine paper is pasted with a high-gloss transparent material. The step 1 comprises three procedures of coating the base material with the triamine glue, pasting the melamine paper and hot-pressing and bonding at high temperature, and the step 2 comprises three procedures of waiting for the melamine paper to be firmly bonded, coating the surface of the melamine paper with the hot melt glue and pasting the highlight transparent PVC/PET surface material. However, the above process has the following disadvantages: because the hot-press bonding generally needs 1 minute, each produced plate needs at least 1 minute to wait, and the high-gloss transparent material can be pasted after the triamine glue is completely cured, so the production period is long; continuous production cannot be realized, and the traditional process has the defects that the steps 1 and 2 are finished by two production lines, so that the efficiency is low; the cost of the melamine paper is high; the roughness of substrate is not high, and melamine paper can reach the effect of veneer, but still can't solve the problem of substrate surface unevenness after having pasted melamine paper, and paste the pursuit to panel veneer effect on the market alone one melamine paper can't be satisfied, so need add highlight plane materiel membrane behind the back and carry out highlight veneer effect, nevertheless because the substrate surface after traditional pasting melamine paper is the unevenness still, does the highlight product and has the flaw easily, orange peel appears easily, the yields is low.

The present invention is directed to solving at least one of the problems of the prior art described above. Therefore, the hot-melt paint decorative panel and the preparation method thereof provided by the invention have the advantages of continuous production, high efficiency, short period, high yield and lower cost.
The invention provides a hot-melt paint decorative panel which comprises a base material, a polyurethane hot-melt paint layer, a PUR hot-melt adhesive layer and a surface material which are sequentially arranged from bottom to top.
In some embodiments of the invention, the face stock is also coated with a protective film. The protective film is preferably PVC protective film with thickness of 60-70 μm.
In some embodiments of the invention, the facestock is a clear color or clear color highlight PVC or PET film. Because the surface of the base material is not prepared after the polyurethane hot-melt paint is coated on the base material, a pure-color or pure-color high-brightness PVC or PET film material needs to be pasted for decoration.
The invention also provides a preparation method of the hot-melt paint decorative panel, which comprises the following steps:
(1) cleaning a base material, rolling polyurethane hot-melt paint on the base material in a rolling way, and drying to obtain a polyurethane hot-melt paint layer;

The base material is cleaned by a dust removing process on the surface of the base material by using a dust remover, so that the adhesion after the glue paint is coated is ensured to have good adhesive force. The polyurethane hot-melt paint is an air reaction type polyurethane hot-melt paint, is safe and environment-friendly, has no viscosity, and has good filling property. The PUR hot melt adhesive is a moisture reaction type polyurethane hot melt adhesive, is safe and environment-friendly, and has good initial viscosity and good adhesive strength. The infrared heat preservation is to prolong the opening time of the glue, which is beneficial to better bonding and the preservation of the initial bonding property of the glue.
In some embodiments of the present invention, the method further comprises a step of rolling the surface of the plate to cover the protective film after the surface material is laminated. The protective film is used for protecting the surface of the product, and the surface of the product cannot be scratched after the product is off-line or in the transportation process.
In some embodiments of the present invention, after the surface material is pressed or the protective film is pressed, the process of trimming and beveling is further included, which is to trim the surface material and the protective film on the surface of the substrate to make the contour of four sides of the product completely consistent with the specification and shape of the substrate, so as to make the product more beautiful.

In some embodiments of the present invention, in the step (1), the temperature of the drying is 40 to 60 ℃.
In some embodiments of the invention, in the step (2), the temperature of the roller for rolling the PUR hot melt adhesive is 120-130 ℃, and the coating weight is 35-40g/m2。
In some embodiments of the invention, in step (2), the temperature of the infrared incubation is in the range of 55-65 ℃.
In some embodiments of the invention, in step (2), the pressing height of the press face material is the thickness of the sheet minus 0.3-0.5 mm.
In some embodiments of the invention, when the facestock is a patch, the step of pressing the facestock is: firstly, pasting the sheet and then rolling the sheet. When the surface material is a coiled material, the step of pressing and pasting the surface material is as follows: the coiled material is directly pressed on the plate by a roller press. No matter the sheet material or the coiled material is pasted, rolling and pressing can be carried out, so that the bonding effect is more compact and firm.
The invention also provides application of the hot-melt paint decorative panel in home decoration and buildings.
