Embodiment 1

[0015] The manufacture method of fiberboard in the present embodiment comprises the following steps:

[0016] A. After the stalks are screened, they are pulverized into powder to 20 mesh to obtain plant fiber powder for subsequent use;

[0017] B, soak magnesium chloride in water for 30 hours, be mixed with 25 degrees of magnesium chloride aqueous solution, add 20 parts of magnesium chloride aqueous solution to parts by weight of 10 parts of plant fiber powder, 35 parts of magnesium oxide, 15 parts of perlite powder and 3 parts of redispersible latex powder Mix well to form a mixture;

[0018] C. Pour the mixture into the slab forming mold, place a glass fiber net on the surface of the mixture, vibrate the slab forming mold, fill the pits formed after the vibration with the mixture, and cold press 2 at room temperature with a 600-ton press minute;

[0019] D, demoulding, take out the cured slab, carry out natural curing, and air-dry outdoors naturally for 6 hours to obtain t...

Embodiment 2

[0021] The manufacture method of fiberboard in the present embodiment comprises the following steps:

[0022] A. After the straw is screened, it is pulverized into powder to 30 mesh, and the plant fiber powder is obtained for subsequent use;

[0023] B, soak magnesium chloride in water for 32 hours, be mixed with 28 degrees of magnesium chloride aqueous solution, add 45 parts of magnesium chloride aqueous solution to parts by weight of 30 parts of plant fiber powder, 45 parts of magnesium oxide, 25 parts of perlite powder and 8 parts of redispersible latex powder Mix well to form a mixture;

[0024] C. Inject the mixture into the slab forming mold, place a glass fiber net on the surface of the mixture, vibrate the slab forming mold, fill the pits formed after the vibration with the mixture, and cold press 6 at room temperature with a 1200-ton press minute;

[0025] D, demoulding, take out the cured slab, carry out natural curing, and air-dry outdoors naturally for 12 hours t...

Abstract

The invention discloses a method for manufacturing a fiber board, and relates to the technical field of artificial boards. The method comprises the following steps: straw is smashed into powder of 20 meshes to 30 meshes, and plant fiber powder is obtained for standby application; water is added into magnesium chloride to prepare magnesium chloride water at the temperature of 25 DEG C to 28 DEG C, and the plant fiber powder, magnesium oxide, crushed crude pearlite and redispersible powder are added into the magnesium chloride water to be evenly stirred to form a mixed material; the mixed material is injected into a slab die, a glass fiber net is placed on the surface of the mixed material, the slab die is vibrated, a pit formed after vibration is filled up and flattened through the mixed material, and cold press molding is carried out on the mixed material at the room temperature; die releasing is carried out, a cured slab is taken out to be naturally maintained, and the finished product is obtained. Compared with the prior art, the manufactured fiber board is stable in quality, good in appearance andwaterproof performance, high in strength and durable in use, and insulates heat.

Description

technical field [0001] The invention relates to the technical field of wood-based panels, in particular to a method for manufacturing fiber panels. Background technique [0002] Wood-based panels are made of wood or other non-wood plants as raw materials. After processing, they are glued together with or without additives. It solves the problem of wood shortage. Fiberboard is a wood-based panel made of wood fiber or other vegetable fiber, which is interwoven with cellulose fibers and made of its inherent adhesive properties or adhesives. It is one of the most common wood-based panels in the building materials market industry. However, in the existing production process of plant fiberboard, the addition of plant fiber raw materials such as straw will change the pore structure inside the slab, and there are problems such as many bubbles, poor water resistance, low strength and easy deformation. Contents of the invention [0003] The purpose of the present invention is to pr...
