Embodiment 1

[0026] A preparation process of a composite board according to the present invention is characterized in that it is sent to a constant temperature and humidity environment for constant temperature and humidity balance treatment during the raw material processing of the base material and the post-processing process of the product, thereby reducing the produced The probability of product deformation and stabilize its physical properties. Among them, the constant temperature and humidity balance treatment process is carried out in a constant temperature and humidity room equipped with an ultrasonic humidifier and a dryer to ensure that the indoor humidity is kept within an appropriate range.

[0027] In this embodiment, the composite board is a melamine veneer decorative board, and the specific steps of its preparation process are:

[0028] a. Ingredients, and send the raw materials into a constant temperature and humidity environment for constant temperature and humidity balance...

Embodiment 2

[0035] The composite plate is a PCB drilling backing plate, and the specific steps of its preparation process are:

[0036] a. Ingredients, and send the raw materials into a constant temperature and humidity environment for constant temperature and humidity balance treatment, keep the temperature: 25 degrees, humidity: 65%;

[0037] b. Plate dust removal, glue coating, billet assembly, hot pressing, edge cleaning, cooling;

[0038] c. Send it again to a constant temperature and humidity environment for constant temperature and humidity balance treatment, keep the temperature: 25 degrees, humidity: 65%;

[0039] d. Classification and finished product packaging.

[0040] In the process step b, after the board is dedusted, the first and second dipped decorative paper layers are respectively pressed and pasted on the upper and lower sides of the wood fiber board layer, and then the hot pressing process is carried out. Cooling in an environment of 36 degrees, the cooling time is ...

Abstract

The invention discloses a preparation technology of a composite plate material. The preparation technology is characterized in that a raw material of a preparing base material respectively enters a constant temperature and constant humidity environment to be subjected to constant temperature and humidity equalization treatment in a processing and product later period processing working procedure. The preparation technology provided by the invention has the advantages that the deformation probability of the produced plate material is reduced, a physical property is stable (the moisture content is stable), the drying and cracking are not easy, the technology is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of composite board production, and more specifically relates to a preparation process of composite boards. Background technique [0002] Melamine board, also known as double veneer, is also a kind of composite board. Its base material is generally particleboard and MDF, which are bonded between the base material and the surface. The surface veneer is treated with fire prevention, abrasion resistance, and waterproof soaking, and its use effect is similar to that of composite wood flooring. In the production process, 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 Or other hard fiberboard surface, a decorative board made by hot pressing. [0003] Special backing plate for PCB drilling, it is a kind of material placed under the board to be...
