preparation example Construction

[0030] Preparation of the modified inner panel: Put the camphor wood into a pulverizer and grind it for 30 minutes to obtain ground camphor wood. Mix the ground camphor wood and water at a mass ratio of 1:10 and put it into a beater Beat the pulp for 20 minutes to obtain wood pulp, put the wood pulp into the blasting tank, send water vapor with a temperature of 180°C to the blasting tank, increase the pressure inside the blasting tank to 1.0 MPa, and hold the pressure for 6 minutes, then discharge the material to obtain micro explosive wood pulp;

[0031] Mix the above-mentioned micro-exploded wood pulp and peanut oil evenly in a mass ratio of 3:2 to obtain a fermentation substrate, put the fermentation substrate into a fermentation tank, and mix 22 parts of fermentation substrate, 1.2 parts of river bottom Sludge, 4 parts of distilled water, 1 part of glucose and 0.3 part of potassium chloride were added to the fermenter, and the fermenter was placed in a greenhouse with a te...

Abstract

The invention discloses a preparation method of a sandwich plate, and belongs to the technical field of decorative material preparation. According to the preparation method, firstly, camphorwood is used as a raw material, and the camphorwood has the effects of insect prevention, mildew prevention and sterilization, so that the insulation property of an internal plate is greatly increased; then peanut oil is used a raw material, and micro-blasting wood pulp and the peanut oil are mixed and fermented, so that the internal plate of the preparation method has the effects of moisture protection, sterilization and bacteriostasis; zinc powder is soaked in a lanthanum nitrate solution, so that a lanthanum oxide protective film is formed on the surface of the zinc powder, the relative contact angleof the zinc powder is increased by the lanthanum oxide protective film, and the fire resistance of the zinc powder is good, so that an external plate has excellent flame resistance due to the use ofthe zinc powder; then sardines bones are used as raw materials, the sardines bones contain a large amount of fluorine, the fluorine has hydrophobicity, so that the moisture resistance of the modifiedzinc powder is increased, the modified zinc powder is used as the raw material to prepare the external plate, and two modified external plates are respectively bonded to the front and back surfaces ofthe modified internal plate by epoxy glue so as to prepare the sandwich plate. The preparation method has wide application prospects.

Description

technical field [0001] The invention discloses a method for preparing a sandwich panel, which belongs to the technical field of preparation of decorative materials. Background technique [0002] Sandwich panels are composed of two layers of formed metal panels (or other material panels) and a polymer heat insulation core that is directly foamed and cured in the middle of the panels, which is easy to install, lightweight and efficient. The filling system also uses a closed-cell molecular structure, which can prevent condensation of water vapor. The forming of the outer steel plate fully considers the structure and strength requirements, and takes into account the aesthetics, and the inner surface is formed into a flat plate to meet various needs. Sandwich panel is a common product in current building materials. It can not only be good for flame retardant and sound insulation, but also environmentally friendly and efficient. [0003] Sandwich panels are divided into the foll...
