preparation example Construction

[0027] The application also provides a method for preparing a sound insulation board, comprising the following steps:

[0028] mixing the corn stalk inner core with a mass ratio of (20-30):(18-22) with a binder, and pre-pressing to obtain a slab;

[0029] The slab is pressurized and solidified to obtain a sound insulation board.

[0030] In the process of preparing the sound insulation board, the applicant firstly mixes the corn stalk core with the binder and pre-presses to obtain a slab, then pressurizes the slab, solidifies and shapes it, and obtains the sound insulation board.

[0031] The pressurized pressure is preferably 1.0-1.8 MPa, the temperature is 100-150° C., and the pressurized time is preferably 45-60 s.

[0032] The present application also provides a door with a corn stalk core sound insulation board as the internal filling material, the door includes a first door panel, a sound insulation board and a second door panel arranged in sequence, and the sound insul...

Embodiment 1

[0037] Mix 25kg of corn stalk inner core with 20kg of binder, stir evenly, and pre-press into a billet, wherein the binder includes 18.75kg of urea-formaldehyde resin, 0.42kg of ammonium chloride and 0.83kg of paraffin, corn stalk The fiber length of the inner core is 100-150mm; then pressurize at 120°C to 1.5MPa, keep it for 45-60s, solidify and form, and obtain a sound insulation board.

Embodiment 2

[0039] Mix 20kg of corn stalk inner core with 18kg of binder, stir evenly, and pre-press into a billet, wherein the binder includes 17.16kg of urea resin, 0.08kg of ammonium chloride and 0.76kg of paraffin, corn stalk The fiber length of the inner core is 100-150mm, which is 75%, and the remaining fiber length is 200-300mm; then pressurize 1.5MPa at 120°C, keep for 45-60s, and solidify and form to obtain a sound insulation board.

Abstract

The invention provides a sound insulating board which comprises inner cores of corn stalks and an adhesive, wherein the mass ratio of the inner cores of corn stalks and the adhesive is (20-30): (18-22). According to the sound insulating board provided by the invention, the inner cores of corn stalks are taken as a material which is reasonably matched with the adhesive to form a novel material. The novel material is remarkable in sound insulating property. By using the novel material as the sound insulating board, the sound insulating property of the sound insulating board is remarkably improved. The invention further provides a preparation method of the sound insulating board. The invention further provides a door which comprises a first door plate, the sound insulating board and a second door plate arranged in an overlaid manner sequentially. The sound insulating board comprises the inner cores of corn stalks and the adhesive, wherein the mass ratio of the inner cores of corn stalks and the adhesive is (20-30): (18-22).

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a sound insulation board, a preparation method thereof and a door. Background technique [0002] Theoretically speaking, general objects have sound insulation effect, but the panels with an average sound insulation of more than 30dB are usually called sound insulation panels. The sound insulation board has the following characteristics: large sound insulation, high sound absorption coefficient, weather resistance and durability, beautiful, economical, convenient, safe, light, fireproof, high strength, waterproof, dustproof and durable. [0003] At present, with the improvement of the quality of life, people's requirements for personal privacy are getting higher and higher, so the application of sound insulation panels in home decoration is also increasing. There are many sound insulation panels on the market, but they are relatively expensive, and the mater...
