Problems solved by technology

[0003] Poor water resistance is a defect that hinders the development of glass magnesium board. Due to the structural characteristics of hydration products, the board is easy to return to halogen, warp and deform when used in a humid environment, which limits the scope of use and service life of glass magnesium board.

Abstract

The invention discloses a fracture-resistant glass magnesium board containing modifying agents such as EVA emulsion. The glass magnesium board is characterized in that the glass magnesium board is prepared from the raw materials of, by weight, 44-46 parts of light-burned magnesium oxide, 38-40 parts of magnesium chloride hexahydrate, 1-2 parts of a crosslinking agent TAC, 9-11 parts of charred wood shavings, 3-5 parts of papermaking black mud, 3-4 parts of EVA emulsion, 4.5-5 parts of metakaolin, 2.5-3 parts of aluminum dihydrogen phosphate, 5-7 parts of tourmaline powder, 0.2-0.25 parts of a silane coupling agents kh550, 1.5-2 parts of waterborne polyurethane, 9-11 parts of a polyvinyl alcohol solution with a concentration of 5%, 15-18 parts of thermoplastic phenolic resin, 5-6 parts of a urotropine water solution with a concentration of 25%, 1.5-2.5 parts of nano-grade zirconia, and an appropriate amount of water. According to the invention, a layer of phenolic resin is finally coated on the surface of a formed board material, such that board corrosion caused by the external environment is reduced. The product is safe and environment-friendly, and has the advantages of convenient construction, high fracture resistance, and high quality.

Description

Technical field [0001] The invention relates to the field of decorative materials, in particular to a flexural magnesium board containing modifiers such as EVA emulsion and a preparation method thereof. Background technique [0002] Magnesium oxychloride gel material is a kind of gas-setting material, which has the energy-saving function of producing products without burning and steaming. Magnesium oxychloride material has excellent physical and mechanical properties, and it has outstanding fire resistance and wear resistance, making This material is widely used in construction engineering, municipal engineering, agricultural production, environmental protection industry, machinery packaging, transportation and light industry. The glass magnesium board is the leading product in the magnesium oxychloride gel material industry. It has outstanding fire resistance and the fire resistance limit can reach 1-4 hours. It has excellent flexural resistance, impact resistance, heat insulati...
