Abstract
A kind of hydrophobic self-cleaning magnesite wallboard, including architectural surface made of decorative magnesia cement mortar（1）, ultralight filled layer made of plant fiber and perlite composite magnesite cement mortar（2）, chopped strand activeness and quietness magnesia cement mortar structure layer（3）And super-hydrophobic layer（4）.Product is coated in magnesite surfaces of wall by micro-nano structure coating, the sandwich construction of ultralight filled layer is wrapped up in conjunction with decorative layer and structure sheaf, effectively improve the intensity and water resistance of glass magnesium board, use nano-tourmaline in formula simultaneously, its anion discharged can purify air, be conducive to health.
Description
Technical field
The present invention relates to a kind of hydrophobic self-cleaning magnesite wallboards, are suitable for the necks such as building roof, building curtain wall, wall decoration
Domain.
Background technology
China's magnesite resource is abundant, and abundant raw material are provided to prepare magnesite product.Magnesite product is by active oxygen
Change magnesium and aqueous salt brine mixes and stirs magnesium gelatinous material made of molding, maintenance hardening.It has many excellent performances, belongs to environmental protection
Building materials, fireproof building material are good substitute for wood.It is popular in American-European and Japan, there have been a considerable amount of systems in China
Row products export.But it since the article water resistance is poor, easily makes moist and returns halogen, influence construction quality, cause the application of magnesite product
It is restricted, also directly affects the outlet of product.Therefore, can the scumming that solve magnesite product become its development and application
Key.
Invention content
In view of the above-mentioned problems, using nano-tourmaline for anion releasable material, carry out low-surface-energy to it changes the present invention
Property, in the magnesite board product surface constructing super-drainage self-cleaning coat with decoration functions, make with negative ion releasing function
Self-cleaning magnesite wallboard.
Technical scheme is as follows：
