Embodiment 1

[0021] The production process of reinforced anti-mildew MDF comprises the following steps:

[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: The raw materials in step S1 are pulverized and transported to the mixer, and the distilled bamboo vinegar is sprayed while stirring, and the added amount is 5-15% of the absolute dry mass of the raw materials;

[0024] 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;

[0025] 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;

[0026] S5: Use high temperature resistant glue to bond the multi-layer MDF;

[0027] S6: Use a hot press to press and paste the multi-layer MDF;

[0028] S7: Use a cold press to stick waterproof and fire-resist...

Abstract

The invention discloses a production method of a reinforcing type mould proof medium density fiberboard. The production method comprises following steps of S1, raw material preteatment; S2, smashing the raw material in the S1, and spraying distilled bamboo vinegar while stirring is carried out; S3, feeding the obtained raw material in the S2 into a high-temperature heat treatment machine; S4, mixing a mould proof adhesive into the raw material dried in the S3, performing pressing in a cold press, and forming the medium density fiberboard; S5, using high-temperature-resisting glue to carry outbonding treatment on multiple layers of medium density fiberboards; S6, using a hot press to carry out pressing treatment on the multiple layers of medium density fiberboards; and S7, using the cold press for attaching waterproof flame-proof paper to the upper surface and the lower surface of the medium density fiberboard in the S6. The multiple layers of medium density fiberboards are bonded, thestrength of the medium density fiberboards is reinforced, meanwhile, during preparing, the distilled bamboo vinegar is sprayed to the raw material, high-temperature treatment is carried out, the mould proof effect is effectively achieved, the preparing process is reasonable and simple, the cost is low, surface machining 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 mold-proof MDF. 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 made of a man-made board after hot pressing, but the surface of the existing MDF is not smooth and firm after splicing, and its water resistance and mildew resistance are relatively poor. Reduced the service life and range of use of MDF. Contents of the invention [0003] The purpose of the present invention is to solve the defects of poor anti-mildew performance of MDF in the prior art, and provide a production process for reinforced anti-mildew MDF. [0004] The present invention is achieved through the following technical solutions: [0005] The production proces...
