Anticorrosive enhanced glass fibre and magnesium board for architectural decoration and preparation method thereof

Abstract

The invention discloses an anticorrosive enhanced glass fibre and magnesium board for architectural decoration. The anticorrosive enhanced glass fibre and magnesium board for architectural decoration is characterized by being prepared from the following raw materials, by weight, 5-7 parts of tourmalinite powder, 42-45 parts of light calcined magnesia, 40-42 parts of magnesium chloride hexahydrate, 0.2-0.25 part of a silane coupling agent kh550, 1.5-2 parts of waterborne polyurethane, 6-8 parts of 5% polyvinyl alcohol solution, 5-7 parts of talcum powder, 7-9 parts of basalt fibre, 4.5-5 parts of metakaolin, 2.5-3 parts of aluminium dihydrogen phosphate, 0.6-0.8 part of a water reducer UNF-2, 15-18 parts of thermoplastic phenolic resin, 5-6 parts of 25% urotropine aqueous solution, 1.5-2.5 parts of aluminium silicate fibre and a proper amount of pure water. By combination of adding a modifier and coating a resin layer, corrosion resistance and waterproofness of the glass fibre and magnesium board are greatly enhanced. Meanwhile, the glass fibre and magnesium board contains tourmalinite powder and can release negative ions which are beneficial to human body. Thus, the anticorrosive enhanced glass fibre and magnesium board is very suitable to be used as a building decoration material.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to an anti-corrosion enhanced glass magnesium board for architectural decoration and a preparation method thereof. Background technique [0002] Magnesium oxychloride gel material is an air-condensing 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 it This material is widely used in construction engineering, municipal engineering, agricultural production, environmental protection industry, machinery packaging, transportation and light industry. 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 bending resistance, impact resistance, heat...

AI Technical Summary

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.
