Abstract

A hydrophobic self-cleaning magnesite wallboard comprises a decorative surface layer (1) made of decorative magnesite cement mortar, an ultra-light filling layer (2) made of plant fiber and perlite composite magnesite cement mortar, a chopped fiber reinforcing and toughening magnesite cement mortar structural layer (3) and a superhydrophobic layer (4), accordint to the hydrophobic self-cleaning magnesite wallboard, the surface of magnesite wallboard is coated with micro-nano structure coating, by combining with the sandwich structure that the ultra-light filling layer is wrapped with the decorative layer and the structural layer, the strength and waterproofing performance of the glass-magnesium board is effectively improve , at the same time, nano tourmaline is adopted in the formula, andthe negative ions released by the nano tourmaline can purify the air, which is beneficial to human health.

Description

technical field [0001] The invention relates to a hydrophobic self-cleaning magnesite wallboard, which is suitable for the fields of building roof, building curtain wall, wall surface decoration and the like. Background technique [0002] my country is rich in magnesite resources, which provide abundant raw materials for the preparation of magnesite products. Magnesite products are magnesium cementitious materials formed by mixing activated magnesium oxide and brine solution, curing and hardening. It has many excellent properties, belongs to environmental protection building materials, fireproof building materials, and is a good wood substitute. It is very popular in Europe, America and Japan, and a considerable number of series products have been exported in my country. However, due to the poor water resistance of this product, it is very easy to get damp and return to brine, which affects the quality of the project, which limits the application of magnesite products and ...
