Embodiment 1

[0024] Embodiment 1: the method for processing the biomimetic reinforced plate with 5-layer structure:

[0025] (1) Preparation of various billets

[0026] a. Coarse material

[0027] The stalks of corn, sorghum or sunflower crops are crushed, removed, and then cut into 2-5cm coarse materials with a pulverizer.

[0028] b. fine material

[0029] The above-mentioned coarse material is made into a fine material with a particle size of 30-50 mesh through a pulverizer.

[0030] c. Reinforcing material

[0031] Bamboo or reed is split and cut to make strip bars or twisted and woven into mesh bars, and then impregnated or glass tempered.

[0032] (2) Slab paving

[0033] In the same mold, the fine material and the coarse material are laid into the mold through the feeding sizing funnel in turn, and the glue is sprayed while spreading the material (this can reduce the amount of sizing in an appropriate amount, and can achieve uniform sizing and reduce environmental pollution). ...

Embodiment 2

[0040] Embodiment 2: the method for processing the biomimetic reinforced plate with 7-layer structure:

[0041] Its 7 layers are: the middle is a reinforced layer, and the two sides of the reinforced layer are respectively a coarser layer, a semi-coarse layer, and a fine material layer.

[0042] Its processing method is different from Example 1 in that its thicker layer uses bamboo as a raw material to process a blank with a length of 3-5cm; The straw is processed into blanks, and the material of the reinforced layer is processed into reticular tendons using wicker.

[0043] The board processed by Example 2 is suitable for places requiring higher strength.

[0044] Utilize the sheet material processed by the present invention to have following technical index: density (bulk density) 0.4g / cm 3 ~0.8g / cm 3 ; The strength is not less than 39.0Mpa; the water absorption is not more than 20%; the water content is 3.0-10.0%.

[0045] Utilize the kind of processing of the present i...

Abstract

The present invention relates to a technological process of producing non-timber fiber board with crop stalk as main material. During the semi-drying process, different material is adopted based on different use, and the produce process includes spraying adhesive, spreading, pressing, and other steps. The spread layers include middle reinforcing rib layer, coarse material layers and fine material layers on two sides. The adhesive is polymer adhesive of dialdehyde starch, protein complex or water soluble polymer resin. The present invention has the advantages of short production period, high strength, low cost and no environmental pollution.

Description

technical field [0001] The invention relates to a method for processing bionic reinforced boards, which belongs to the technology of producing and processing non-wood fiber boards with crop stalks as the main raw material. Background technique [0002] Chinese patent CN1031959A discloses a "man-made composite board and its manufacturing method", which is mainly composed of vegetable materials, inorganic mineral materials and adhesives, including coarse material layers and fine material layers, or with reinforcement, The binder used is glutinous rice thinner and modified urea-formaldehyde resin glue. Its processing method belongs to the wet method, that is, after the material is pulverized, it needs to be boiled with alkali. The disadvantage of wet processing is that it consumes a lot of water and pollutes the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing method of biomimetic strength...
