Manufacturing method of multilayer composite paint-free molded three-dimensional board, and system applied to manufacturing method

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.

Description

technical field [0001] The invention relates to the technical field of building material manufacturing, in particular to a method and system for manufacturing a multi-layer composite paint-free molded three-dimensional board. Background technique [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 ...

[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.
