Embodiment 1

[0021] A kind of manufacture technology of fire-resistant MDF, comprising the steps of:

[0022] S1: Using wood fiber or other plant fiber as raw material, crushing, fiber separation and drying treatment, the moisture content of the raw material is 11% to 12%;

[0023] S2: Mix the dried raw materials with an anti-mildew adhesive, and press them in a cold press to form MDF;

[0024] S3: Fill the gaps around the MDF with epoxy resin;

[0025] S4: Coating magnesium oxide gel material on the upper surface of the MDF in step S3;

[0026] S5: Coating the magnesium chloride gel material on the lower surface layer of the MDF in step S4;

[0027] S6: curing;

[0028] S7: Use a cold press to stick waterproof and fire-resistant paper on the upper and lower surfaces of the MDF in step S6.

[0029] Wherein, the epoxy resin is epoxy resin powder, and the particle size of the powder is 35-40 microns.

[0030] The anti-mold adhesive is prepared by adding antibacterial and anti-mold fragr...

Abstract

The invention discloses a manufacturing technology of a fireproof medium density fiberboard. The technology comprises the following steps: S1, preprocessing raw materials; S2, forming the medium density fiberboard; S3, filling seams surrounding the medium density fiberboard with epoxy resin; S4, coating an upper surface layer of the medium density fiberboard obtained in step S3 with a magnesium oxide gel material; S5, coating a lower surface layer of the medium density fiberboard obtained in step S4 with a magnesium chloride gel material; S6, curing; and S7, adhering waterproof fireproof paperon the upper and lower surfaces of the medium density fiberboard obtained in step S6 through a cold pressing machine; filling seams surrounding the medium density fiberboard with the epoxy resin so as to lock water in the medium density fiberboard as well as avoid cracks and bubbles. According to the technology, the upper surface and the lower surface of the medium density fiberboard are correspondingly coated with magnesium oxide gel and magnesium chloride gel, and the waterproof fireproof paper is adhered, so that the medium density fiberboard is fireproof, reasonable and simple in preparation process, low in cost, high in surface processing performance, and suitable for industrial production.

Description

technical field [0001] The invention relates to a preparation method of an artificial board, in particular to a preparation process of a fireproof MDF. Background technique [0002] Although the current powder spraying technology on the surface of MDF can better meet the requirements of surface treatment, in the traditional process, MDF is often stored in a space with high humidity for a long time, and the strong water absorption of MDF will cause water penetration. If it penetrates into the surface of the board, it will cause cracks on the edge and bubbles on the surface, which will affect the quality; secondly, it does not have the effect of fire prevention. Contents of the invention [0003] The object of the present invention is to provide a production process of fireproof MDF in order to solve the disadvantages of MDF in the prior art, such as poor anti-mildew performance. [0004] The present invention is achieved through the following technical solutions: [0005]...
