Problems solved by technology

This laminating method has the following disadvantages: the material is only heated and compacted between the lower mirror roller and the upper mirror roller, which to a certain extent wastes the utilization efficiency of the lower mirror roller and the upper mirror roller; After the grinding film and the printing film are bonded, after the embossing roller and the embossing roller are bonded, the plate is directly discharged without heating and calendering. The color film layer that is directly attached to the material is located under the wear-resistant film, and does not directly contact the high-temperature calender roll, which is more likely to cause loose bonding and a high rate of defective products

Embodiment Construction

[0025] The specific implementation manners of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the embodiments described in the specific implementation are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The invention provides a production process of a separated film-coated plate.

[0027] Before starting processing, heat and keep warm the extruder, mold and other equipment in advance to ensure that the material is extruded from the powder into the solution. If the temperature is not enough to start the machine, it is easy to cause damage to the extruder screw and reducer or even scrap it. Concrete plate production method comprises the followi...

Abstract

A board production method includes: mixing materials, performing melt extrusion, coating an extruded blank, cooling and cutting. The coating is characterized by including the steps of firstly, performing first-stage heating and compacting on the extruded blank, and coating the surface on one side of the extruded blank with a first layer of film in the process of the first-stage heating and compacting; secondly, performing at least one second-stage heating and compacting on the extruded blank after the first compacting; thirdly, performing third-stage heating and compacting on the heated extruded blank, and coating the surface of the first layer of film with a second layer of film in the process of the third-stage heating and compacting. The method has the advantages that the second-stage heating and compacting is performed on the blank coated with the first layer of film, the fitting degree of the first layer of film and the blank is increased, a plasticizing effect on the first layerof film is achieved at the same time, then the second layer of film is coated, and the fitting degree of the second layer of film and the blank can be also increased.

Description

technical field [0001] The invention relates to the field of sheet material processing, and specifically relates to a sheet material processing method. Background technique [0002] Stone-plastic panels and wood-plastic panels have gradually increased their market share due to their advantages in environmental protection, moisture resistance and water resistance. The processing technology of this type of board usually includes mixing materials with a mixer, extruding materials in layers from an extruder, extruding and shaping through a die, and then forming after high-temperature compaction and shaping. [0003] Some boards also need to be covered with a film during the extrusion molding process, and the requirements for the coating treatment are also different. Some boards need to be multi-layered. For example, some boards require Cover a layer of ornamental color film, in order to enhance the wear resistance of the board, a layer of wear-resistant film will be covered on ...
