Example Embodiment

[0035] Example 1

[0036] Weigh the raw materials (kg) according to the following weight:

[0037] Magnesium cement 100, carbon fiber 0.5, glass fiber 0.5, vegetable fiber 0.5, sodium lauryl sulfate 0.42, emulsifier OP-100.28;

[0038] The manufacturing method of the light-weight, energy-saving, heat-insulating, sound-insulating and fire-proof door core panel includes the following steps:

[0039] (1) Mix 0.42 kg of sodium lauryl sulfate and 0.28 kg of emulsifier OP-10 to prepare a foaming agent;

[0040] (2) Put bundled chopped fibers with a length between 1 cm and 3 cm into the mixer, add one third of the brine to soften the total weight of the weighed raw materials, that is, about 34 kilograms of brine, under the mixing of the stirring blade Disperse the chopped fibers, add magnesium cement and pre-mixed foaming agent, stir for 7 minutes, 0.5 kg of carbon fiber, 0.5 kg of glass fiber, and 0.5 kg of plant fiber are evenly distributed in 100 kg of magnesium cement slurry to obtain mag...

[0043] Example 2

[0044] Weigh the raw materials (kg) according to the following weight:

[0045] Magnesium cement 90, carbon fiber 0.2, glass fiber 0.2, vegetable fiber 0.1, sodium lauryl sulfate 0.6, emulsifier OP-10 0.4;

[0046] The preparation method is as in Example 1.

Example Embodiment

[0047] Example 3

[0048] Weigh the raw materials (kg) according to the following weight:

[0049] Magnesium cement 110, carbon fiber 1, glass fiber 0.5, vegetable fiber 0.5, sodium lauryl sulfate 0.3, emulsifier OP-10 0.2;

[0050] The preparation method is as in Example 1.

[0051] Product specifications of the invention:

[0052] Length: 800-2400mm

[0053] Width: 600-1200mm

[0054] Thickness: 15-100mm

[0055] Application of the product of the invention:

[0056] 1. Lightweight partition walls, light fire partitions, heat and sound insulation walls, partitions;

[0057] 2. Thermal insulation materials;

[0058] 3. Filling material for fire door core.

[0059] Because the magnesium cement product is an exothermic chemical reaction during curing, its heat release rate is higher, and the temperature can reach 110~125℃ (related to the ambient temperature during molding); at the same time, its exothermic reaction time is relatively concentrated (about 20 minutes) About), there will be a lot o...

Abstract

The invention discloses a preparation method of a light, energy-saving, heat-proof, sound-proof and fireproof door panel. The door panel comprises the following raw materials in parts by weight: 90-110 parts of magnesia cement, 0.5-2 parts of chopped fiber and 0.5-1 part of foaming agent, wherein the chopped fiber consists of carbon fiber, glass fiber and vegetable fiber; and the foaming agent is prepared from sodium lauryl sulfate and emulsifier OP-10 according to a ratio of 3:2. The preparation method of the door panel comprises the following steps: mixing chopped fiber, magnesia cement and foaming agent to obtain a magnesia cement product; and placing the magnesia cement product in a special mould box and curing to obtain the finished product. The product disclosed by the invention has the advantages that the product has light weight, high strength and high durability, is mothproof, corrosion-proof and moistureproof, can keep warm, insulate heat, save energy, insulate and absorb sounds, resist fire and is environment-friendly and can be cut, planed and sawed.

Description

technical field [0001] The invention belongs to the field of material preparation, and discloses a formula of a lightweight, energy-saving, heat-insulating, heat-insulating, sound-insulating, and fire-proof door core board and a manufacturing method thereof. Background technique [0002] Most of the existing door core panels on the market use expanded perlite as the main raw material, mixed with a certain proportion of inorganic high-binder and additives, and processed through a whole set of procedures. Perlite products include: high-strength hydrophobic expanded perlite board, hydrophobic perlite insulation board (perlite insulation brick), perlite fire door core board (fire door core board), perlite bulk material, large particle size pearl for gardening Rock, pearlite, perlite filter aid, etc. The performance of the above products is relatively single. [0003] Most of the users of fire door core boards are fire door manufacturers, and the processes of these manufacturer...
