Problems solved by technology

[0002] So far, the multi-layer composite paint-free molded three-dimensional board widely used in the home building materials industry cannot be produced with particleboard as the base material, and all of them are produced with materials other than particle board (the most important of which is fiberboard) , compared with the production of particleboard, the production of fiberboard has high energy consumption and heavy pollution, low utilization rate of forest resources, large amount of formaldehyde release, and the production cost is more than 40% higher
At the beginning of this century, the home building materials industry proposed the subject of producing multi-layer composite paint-free molded three-dimensional boards with particleboard as the base material. The multi-layer composite paint-free molded three-dimensional board produced has technical problems such as easy cracking, dry flowers and easy deformation of the decorative surface layer, which have not been effectively overcome in the industry.

Embodiment 1

[0031] This embodiment discloses a specific embodiment of a method for manufacturing a multi-layer composite paint-free molded three-dimensional panel, including steps:

[0032] S10: impregnating the decorative base paper and the balance base paper in glue to obtain an impregnated decorative paper and an impregnated balance paper;

[0033] S20: Assemble the steel positive formwork with the upper platen of the hot press, and set the steel flat formwork with the lower platen of the heat press;

[0034] S30: adjusting the working pressure of the heat press to a preset pressure, and adjusting the temperature of the heat transfer oil to a preset temperature;

[0035] S40: Put the impregnated decorative paper, the particle board and the impregnated balancing paper into the heat press in sequence according to the laying sequence of the upper layer of decorative paper, the middle layer of particle board and the bottom layer of balancing paper;

[0036] S50: maintaining pressure on th...

Embodiment 2

[0038] This embodiment discloses another specific embodiment of the method for manufacturing a multi-layer composite paint-free molded three-dimensional board, the steps of which are basically the same as those in Embodiment 1, the difference being that in step S10 of the method of this embodiment, dipping Decorative and impregnated balance papers had a volatile content of 7.5% and a precure of 45%.

[0039] Specifically, in step S20, the thickness of the steel male formwork and the rigid flat formwork are both 7.5mm, the height of the convex pattern of the steel male formwork is 5% of the thickness of the particleboard, and the width of the positive pattern is 1 / 4 of the height of the positive pattern. 20 times, the top arc radius of the positive pattern is 35 times the height of the positive pattern, the transition radius of the positive pattern is 20 times the height, the positive pattern is treated with high light, and the gloss of the positive pattern is 180 degrees.

Abstract

The invention discloses a manufacturing method of a multilayer composite paint-free molded three-dimensional board, and a system applied to the manufacturing method. The manufacturing method comprises the steps of S10, impregnating decorative base paper and balance base paper into glue to obtain impregnated decorative paper and impregnated balance paper; S20, using a steel male template to sleeve an upper press plate of a hot press, and using a steel flat template to sleeve a lower press plate of the hot press; S30, adjusting the working pressure of the hot press to a preset pressure, and adjusting the temperature of heat conduction oil to a preset temperature; S40, sequentially putting the impregnated decorative paper, a shaving board and the impregnated balance paper into the hot press in a paving sequence that the decorative paper is positioned at the upper layer, the shaving board is arranged at the middle layer, and the balance paper is positioned at the bottom layer; S50, maintaining the pressure of the hot press, wherein the pressure maintaining time is set in advance. After the manufacturing method and the system are adopted, the multilayer composite paint-free molded three-dimensional board can be obtained by taking the shaving board as a base material; a paint layer does not exist, so that the manufacturing technology is simplified, and the three-dimensional board is environment-friendly; furthermore, the produced three-dimensional board can be directly used for final consumption.
