Abstract
The invention relates to a manufacturing method of a straw density board. The manufacturing method comprises the steps of (1) selecting plant straws; (2) cutting off; (3) cooking the straws at 150 DEG C for more than 1 hour; (4) adding water to the straws, and crushing into particles of which the particle size is less than 3 mm; (5) drying; (6) adding glue to the straw fiber particles, wherein the weight of the glue is 25% to 35% of that of the straw fiber particles; (7) fully mixing; (8) pressurizing on a drying machine for more than 200 kilograms, and forming.
Description
Technical field
The present invention relates to a kind of vegetable fibre board and manufacture method thereof, particularly a kind of densified straw board and manufacture method thereof.
Background technology
The method adopting string to manufacture density board mostly is the ligneous plant stalk manufacture adopting sunflower pole, soybean straw, eggplant bar, waste of flax, straw etc. thin, and needs when manufacturing to add the additive such as anti-blushing agent, curing agent, and manufacturing process is complicated.
Summary of the invention
The object of the invention is to: provide a kind of densified straw board and manufacture method thereof, with the cornstalk reclaimed, rice straw, wheat straw wherein one or more for raw material, product is fine and close, and intensity is high, and manufacturing process is simple.
The present invention is achieved in that a kind of manufacture method of densified straw board, 1. selected straw; 2. cut off; 3. by stalk boiling more than 1 hour at 150 DEG C; 4. stalk is added water and be crushed into the particle that particle diameter is less than 3mm; 5. dry; 6. in stalk fibre particle, the glue that weight is stalk fibre particle weight 25%-35% is added; 7. fully stir; 8. pressurize more than 200 kilograms on heating press, bake pressure, shaping.
The weight of described glue is stalk fibre particle weight 20%.
The manufacture method of described glue is: formaldehyde is heated after 30 DEG C, adding weight is after the urea of formaldehyde weight 40%, heat and add caustic soda to 60 DEG C and make pH value be adjusted to 7.5-8.0 scope, adding ammonium chloride again makes pH value be adjusted to 5.1-4.8 scope, finally adds the urea that weight is formaldehyde weight 11%.
The densified straw board that said method is made, the corner of plate is circular arc.
The present invention is owing to make use of agricultural stalk class discarded object as raw material, and solve crop straw burning and stack the problem of environmental pollution caused, and manufactured goods are fine and close, intensity is high, and manufacturing process is simple; Manufactured goods corner is that circular arc can facilitate using of sheet material and transport.
Below in conjunction with embodiment, the present invention will be further described.
Embodiment 1. is elite corn stalk 100 kilograms 1.; 2. cut off; 3. by stalk boiling more than 1 hour at 150 DEG C; 4. stalk is added water and be crushed into the particle that particle diameter is less than 3mm; 5. dry; 6. in stalk fibre particle, the glue that weight is 25 kilograms is added; 7. fully stir; 8. pressurize more than 200 kilograms on heating press, bake pressure, shaping.The manufacture method of described glue is: 50 kilograms of formaldehyde are heated after 30 DEG C, after adding weight 20 kilograms of urea, heat and add caustic soda to 60 DEG C and make pH value be adjusted to 7.5-8.0 scope, then add ammonium chloride and make pH value be adjusted to 5.1-4.8 scope, finally add the urea of weight 5.5 kilograms.
Embodiment 2., according to the method for embodiment 1, selects rice straw, with 35 kilograms, glue.
Embodiment 3., according to the method for embodiment 1, selects wheat straw and rice straw totally 100 kilograms, with 20 kilograms, glue.
Claims (4)
