Embodiment Construction

[0014] Please refer to Fig. 2, the present invention uses a peeling machine to separate the pith from the corn stalks after ear removal and leaf removal, the pith core after separation is used for other purposes, and the epidermis after separation is then cut off as a board-making raw material , usually cut according to the length of 20cm. The cut corn stalk epidermis is then crushed into crushed material with a pulverizer. The mesh size of the pulverizer is 6mm, and the composition of the crushed material is in the following range:

[0015] Particle size (mm)

＜6～4.75

＜4.75～2.26

＜2.26～1.63

＜1.63～1.41

＜1.41～1.096

＜1.096～0.56

＜0.56～0.216

＜0.216

weight percentage (%)

1.00～1.50

6.90～7.30

11.00～11.50

8.20～8.70

6.75～7.15

29.80～30.50

25.00～25.40

9.40～10.40

[0016] Then apply 3.2-3.7% isocyanate adhesive of the weight of the corn stalks to the crumbs and stir evenly,...

Abstract

The invention belongs to the category of cropper straw wood based panel. A maize straw grain plate comprises maize straw broken material and isocyanate adhesive. The invention is characterized in that the maize straw broken material is the grain of the skin of the marrow-removed maize straw; the weight percentage of the grain composition can be seen in the table; the content of the isocyanate is 3.2% to 3.7% times of the weight of the maize straw broken material. The manufacturing method of the maize straw grain plate is that the skin and marrow of the maize straw are removed; the peeled skin of the maize straw is cut off, crushed, screened, glued, paved, pre-pressed, hot pressed under the temperature ranging from 170 DEG C to 175 DEG C and edge cut. The invention solves the technical problems of improving the strength of maize straw crushed grain plate, simplifying gluing and glue mixing process, raising hot pressing temperature and shortening hot pressing time.

Description

Technical field: [0001] The invention belongs to the field of crop stalk-based panels, in particular to an artificial panel using corn stalks as a raw material and a manufacturing method thereof. Background technique: [0002] Since the 1980s, my country has begun to use straws of crops, such as wheat, rice, rapeseed, corn, flax, sugar cane, sunflower, etc., to replace wood to make wood-based panels. In the "Forest Industry" There have been many related reports in the publications, but so far only a few crop straws such as wheat and rice have entered the industry of manufacturing artificial particle boards, and most of the rest of the crop straws have not shown their glory in the wood-based panel industry. Among them, corn straw particle board is an example. Some corn straw board factories successively established in Jilin, Shaanxi, Inner Mongolia, and Heilongjiang failed to persist. The reason is that these enterprises still use the old idea of ​​using the whole straw of crop...
