Problems solved by technology

[0002] With the reduction of wood resources, it is imperative to use crop straw as raw material to produce wood-based panels, but how to develop high-strength, low-cost straw-based panels is very important. At this stage, most enterprises that use straw as raw materials to produce wood-based panels After the straw is pulverized, glue is applied and hot-pressed. This process destroys the fiber structure of the straw, and the strength of the plate produced is low; Leather core, bamboo skin, steel mesh and other materials are added before mold loading. Although the board made can replace wood board, the production process is cumbersome, and adding bamboo skin and steel mesh and other materials increases the production cost; plant fiber building decoration materials and production The main technical feature of the process (CN1887771) is to use straw, rice husk, and peanut shell as raw materials, and compound it through chemical denaturation, but the chemical denaturation process is complicated, and the production has three wastes.

Embodiment 1

[0014] First, one of the four kinds of straws is sent to the whole straw making machine, and the whole straw is processed longitudinally by the making machine into 6mm wide straw strips, the length of which is the natural length of each straw, and then the 6mm The wide stalks are fed into the curtain tying machine, and the stalks are woven by the curtain tying machine into sheet-like stalk curtains with two different stalk placements of the same shape and size, that is, the vertical length of the stalks is 2700mm × horizontal 1300mm ×Layer thickness 10mm This arrangement method makes two pieces, and then according to the arrangement method of 1300mm in the vertical direction of the stalks × 2700mm in the horizontal direction × Layer thickness of 10mm, make one piece, three pieces form a group, and send the three pieces of stalk curtain The integrated machine for drying, glue spraying and billet assembly of double-roller stalk curtains is integrated to complete the work of dryin...

Embodiment 2

[0016] After drying, glue spraying and slab assembly by the integrated machine, before sending it into the hot press, if you want to produce a veneer board, you can stick the veneer of wood veneer or other materials on the back surface of the slab Send into hot press machine again after two sides, just can directly send slab into hot press machine as producing plain panel material, other process conditions are like embodiment 1, can produce qualified panel material equally.

Abstract

The invention discloses a process for producing a straw artificial board, and relates to the artificial board production industry. The process is used for producing the artificial board by substituting wood for crop straws serving as raw materials. A self-made slivering machine, a curtain beating machine and a drying, glue spraying and assembling integrated machine are used in the process; mechanical streamline production of each working procedure of the straw artificial board is realized, the production efficiency is greatly increased, and the production cost is reduced; and the internal structure of the board produced by using the process is scientific and reasonable, the bending strength reaches 52.6MPa, the screw holding force on the board surface reaches 2,140N, various performance indexes are higher than those of the conventional artificial boards and close to those of wood, and the straw artificial board can substitute the wood in many fields and has low manufacturing cost.

Description

Technical field: [0001] A straw-based panel production process relates to the panel production industry, which is a process method of using crop straws as raw materials instead of wood to produce wood-based panels. Background technique: [0002] With the reduction of wood resources, it is imperative to use crop straw as raw material to produce wood-based panels, but how to develop high-strength, low-cost straw-based panels is very important. At this stage, most enterprises that use straw as raw materials to produce wood-based panels After the straw is pulverized, the sizing is hot-pressed and formed. This process destroys the fiber structure of the straw, and the strength of the plate produced is low; Leather core, bamboo skin, steel mesh and other materials are added before mold loading. Although the board made can replace wood board, the production process is cumbersome, and adding bamboo skin and steel mesh and other materials increases the production cost; plant fiber bu...
