Embodiment 1

[0022] The production process of reinforced melamine veneer MDF comprises the following steps:

[0023] 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%;

[0024] S2: The raw materials in step S1 are pulverized and transported to the mixer, and the flame retardant is sprayed while stirring, and the added amount is 5-15% of the dry weight of the raw materials;

[0025] S3: Send the raw material obtained in step S2 into a high-temperature heat treatment machine, and process it at 120-200°C for 30min--150min;

[0026] S4: Mix the dried raw materials in step S3 with an anti-mildew adhesive, and press and stick them in a cold press to form a MDF;

[0027] S5: Put the glass silk mesh layer in the mold frame of the MDF layer, lay it flat, and pre-press;

[0028] S6: preparing a fiberboard layer;

[0029] Carry out waterproof glue treatment on the separated wood fibers ...

Abstract

The invention discloses a production process of a reinforced melamine facing medium density fiberboard. The production process comprises the following steps of S1, pretreating raw materials; S2, crushing the raw materials obtained in S1 and conveying the crushed raw materials to a stirring machine, spraying a flame retardant in the stirring process, wherein the additive amount of the flame retardant is 5%-15% of the absolute dry mass of the raw materials; S3, carrying out high-temperature heat treatment; S4, forming a medium density fiberboard; S5, placing a glass fiber net layer in a mold frame of the medium density fiberboard layer, spreading and prepressing; S6, preparing a fiberboard layer; and S7, pressing and pasting melamine glue-impregnated paper at high temperature on the upper surface of the fiberboard layer and the lower surface of the medium density fiberboard. According to the production process of the reinforced melamine facing medium density fiberboard, the medium density fiberboard, the glass fiber net layer and the fiberboard layer are adopted for bonding treatment, the melamine impregnated paper is added, and meanwhile, the raw materials are sprayed with the flameretardant during preparation, and high-temperature treatment is carried out, so that the flame-retardant effect can be effectively achieved, the preparation process is reasonable and simple, the costis low, the surface processing performance is good, and the method is suitable for industrial production.

Description

technical field [0001] The invention relates to a method for preparing artificial boards, in particular to a production process for reinforced melamine-decorated medium fiber boards. Background technique [0002] Fiberboard is a kind of density board, which can be divided into long density fiberboard, medium density fiberboard and short density fiberboard according to density. Urea-formaldehyde resin or other suitable adhesives are a kind of man-made board made by hot pressing, while melamine veneer, also known as veneer, is made of base materials (medium fiberboard, particle board, moisture-proof board, multi-layer solid wood plywood, etc.) ) and melamine-impregnated paper are pressed and pasted at high temperature. Its advantages are environmental protection, waterproof, simple and convenient, etc. It is the first choice for customized furniture and panel furniture. With the rise of the home decoration industry, more and more customers use melamine decoration. panel decor...
