specific Embodiment approach 1

[0033] Specific Embodiment 1: Combining figure 1 Describe this embodiment, a method for manufacturing a heat-insulating and sound-insulating particleboard in this embodiment, including: S1 material preparation, S2 raw material pretreatment, S3 adding adhesive, S4 layered paving, S5 hot-press forming and S6 post-processing steps , specifically: the S1 material preparation step refers to processing wood or straw through one or more of planing, chipping, rolling, sawing and screening to obtain woody raw materials; S2 raw material pretreatment refers to controlling the moisture content of wood raw materials by controlling temperature and humidity equipment; S3 adding adhesive refers to applying liquid adhesive on the pretreated wood raw materials by spraying method; S4 layered paving refers to adding the added The wooden raw material of the adhesive is divided into multiple parts, one of which is evenly paved in the mould, and then the vacuum tube 7 prepared in advance is directio...

specific Embodiment approach 2

[0035] Specific Embodiment 2: Combining figure 1 and figure 2 Describe this embodiment, the manufacturing method of heat-insulating and sound-insulating particleboard described in this embodiment, the step of directional paving vacuum tube 7 and the step of paving wooden raw materials with adhesive added in step S4 when paving slabs layer by layer Alternately for many times, the vacuum pipe 7 is paved with multiple layers; in the layered paving process, the first layer and the last layer are paved with wooden raw materials with adhesive added; the others are the same as in the specific embodiment 1.

[0036] The technical effect of this embodiment is: due to the adoption of the method, the vacuum tubes can be arranged in multiple layers so that the particle board board can better achieve a low average density and a high surface density, further ensuring the light weight, high strength and good surface processing of the board. Performance; In addition, it is also conducive to...

specific Embodiment approach 3

[0037] Embodiment 3: Combining figure 1 and figure 2 Describe this embodiment, the manufacturing method of heat-insulating and sound-insulating particleboard described in this embodiment, the moisture content of the wood raw material in step S2 is controlled at 10%~15%; the hot pressing equipment described in step S5 is a high-frequency heating Pressure equipment; Others are identical with specific embodiment 1 or 2.

[0038] The technical effect of this embodiment is: controlling the moisture content of the wood raw material and making the wood raw material have a higher moisture content is a method rarely used in the wood processing industry, because the conventional increase of the moisture content will make the performance of the board unstable and unfavorable. The forming of the board generally controls the moisture content of the woody raw material below 5% when the particle board is manufactured, but in the present invention, the moisture content of the board is 10% t...

Abstract

The invention discloses a manufacturing method of a heat and sound insulation particle board, aims to realize manufacturing of a high-strength sound and heat insulation particle board and solving of difficult formation of a closed vacuum environment by such wood composite materials as particle boards, aims to the problem that the particle boards cannot achieve better heat and sound insulation effect in the prior art, and proposes the manufacturing method of the heat and sound insulation particle board. The manufacturing method comprises the steps of: (S1) material preparation; (S2) raw material pretreatment; (S3) adhesive adding; and (S4) layered pavement: wood raw materials added with adhesive are divided into multiple parts; one part is taken out to uniformly pave in a mold; then, vacuum pipes prepared beforehand are paved in an oriented manner; another part of wood raw materials added with the adhesive is taken out to pave on the vacuum pipes paved in the oriented manner; and a plate blank is obtained by prepressing; (S5) hot-press forming; and (S6) later machining. The manufacturing method has the following beneficial effects: the closed vacuum environment is formed in the particle board, so that the particle board has part characteristics of a vacuum material, and the heat and sound insulating performance of the particle board is promoted.

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a method for manufacturing particle boards, in particular to a method for manufacturing heat-insulating and sound-insulating particle boards. Background technique [0002] Particleboard is a wood-based panel made of scraps made of wood or other lignocellulosic materials with adhesives applied, then machined and pressed together. It is an economical substitute product for wood. Particleboard is used in the construction industry and furniture manufacturing industry. Particleboard with superior performance can replace natural wood for the manufacture of wooden structures, interior decoration parts, desks, cabinet furniture, as well as trains and car compartments. [0003] With the advancement of particleboard manufacturing technology and the wide application of wood-based panel products, people's understanding and recognition of wood-based panels is gradually improving, and at the ...
