Problems solved by technology

However, the gluing process of this process uses melamine glue, and its performance becomes weaker with the increase of storage time. It is easy to pollute the board surface and the side of the board when gluing, and the brushing process is likely to cause uneven thickness and density of brushing, which affects the yield. , and the process is complex

Embodiment 1

[0033] The process of pressing and pasting melamine-impregnated paper on the surface of the inorganic board in this embodiment comprises the following steps:

[0034] (1) Smooth the inorganic board through 180-mesh sanding, clean the surface dust, and control the moisture content of the inorganic board to 5%;

[0035] (2) cutting the polymer film into a size consistent with the specifications of the inorganic board, then superimposing the inorganic board and the polymer film, with the smooth side of the polymer film facing upwards, to obtain the assembly A;

[0036] (3) The polymer film and the melamine-impregnated paper are superimposed, and the smooth side of the polymer film faces downward to obtain the assembly B;

[0037] (4) Superimpose the blank group B on the blank group A to form a pre-pressed plate, put the pre-pressed plate in the hot press for heating and pressing, the temperature is 150°C, the pressure is 12Mpa, heating and pressing The pressing time is 40 second...

Embodiment 2

[0039] The process of pressing and pasting melamine-impregnated paper on the surface of the inorganic board in this embodiment comprises the following steps:

[0040] (1) Smooth the inorganic board through 180-mesh sanding, clean the surface dust, and control the moisture content of the inorganic board to 5%;

[0041] (2) Cutting the polymer film into a size consistent with the specifications of the inorganic plate, superimposing the inorganic plate and the polymer film, with the bright side of the polymer film facing up, to obtain the assembly A;

[0042] (3) The polymer film and the melamine-impregnated paper are superimposed, the smooth side of the polymer film faces downward, and the blank B is assembled;

[0043] (4) Superimpose the blank assembly B on the blank assembly A to form a pre-pressed plate, put the pre-pressed plate in the hot press for heating and pressing, the temperature is 160°C, the pressure is 14Mpa, heating and pressing The pressing time is 30 seconds. ...

Embodiment 3

[0045] The process of pressing and pasting melamine-impregnated paper on the surface of the inorganic board in this embodiment comprises the following steps:

[0046] (1) Smooth the inorganic board through 180-mesh sanding, clean the surface dust, and control the moisture content of the inorganic board to 5%;

[0047] (2) cutting the polymer film into a size consistent with the specifications of the inorganic board, then superimposing the inorganic board and the polymer film, with the smooth side of the polymer film facing upwards, to obtain the assembly A;

[0048] (3) The polymer film and the melamine-impregnated paper are superimposed, and the smooth side of the polymer film faces downward to obtain the assembly B;

[0049] (4) Superimpose the blank group B on the blank group A to form a pre-pressed plate, put the pre-pressed plate in the hot press for heating and pressing, the temperature is 150°C, the pressure is 12Mpa, heating and pressing The pressing time is 25 second...

Abstract

The invention discloses a process for pressing and pasting melamine-impregnated paper on the surface of an inorganic plate, which comprises the following steps: (1) sanding the inorganic plate, removing dust, and adjusting the moisture content to obtain a pretreated inorganic plate; (2) The pretreated inorganic plate and the polymer film are superimposed to obtain the blank A; (3) the polymer film and the melamine impregnated paper are laminated to obtain the blank B; (4) the blank B is laminated on On the blank assembly A, a pre-pressed plate is obtained, and then hot-pressed to obtain final product; in step (2) and step (3), the main component of the polymer film is PE or PE graft copolymer. The veneering process of the present invention does not need to be pressed twice, which reduces the physical damage of the inorganic board. The damage of one-time heating and pressing is twice as low as that of the second heating and pressing. The inorganic board with one-time pressing can reach Class A fire prevention.

Description

technical field [0001] The invention relates to the technical field of board decoration technology, in particular to a technology for pressing and pasting melamine-impregnated paper on the surface of inorganic boards. Background technique [0002] Melamine board, referred to as melamine board, the full name is melamine impregnated film paper veneer wood-based board. It is to soak paper with different colors or textures in melamine resin adhesive, then dry to a certain degree of curing, and pave it on particleboard, moisture-proof board, medium density fiberboard, plywood, blockboard, multi-layer board or other Hardboard surface, heat-pressed decorative panels. Various patterns can be copied arbitrarily, with the advantages of scratch resistance, wear resistance, good heat resistance, corrosion resistance, pollution resistance and so on. [0003] The traditional melamine board is to apply glue to the surface of the board, and then spread the non-woven fabric or kraft paper ...
