Description
Technical field
The present invention relates to building material technical field, more particularly to a kind of antibacterial mastic powder.
Background technology
Before class construction is painted during powder of lacquer putty for use on, the flat pulverulent material in a kind of surface that is pre-processed to construction surface, main purpose is
Fill the space of construction surface and correct the curve deviation of construction surface, the lacquer painting to obtain uniform, smooth is laid a solid foundation.
Putty is usually to be made up of base-material, filler, water and auxiliary agent etc..
Base-material, also referred to as binding agent, it is the most critical component of putty, it is various mainly plays bonding etc..Putty is the most frequently used
Binding agent is cement and organic polymer, and organic polymer has point of emulsion and latex powder again.Cement be caking property it is good, it is durable and
The rational binding agent of cost performance, but tensile strength and crack resistance are poor.It can be modified for organic polymer and toughness reinforcing, so as to improve
Putty performance.
Filler mainly plays filling effect, and conventional has calcium carbonate, talcum powder and quartz sand etc..It should be noted that filler fineness is taken
With use.
Auxiliary agent has thickener, water-loss reducer etc..Thickener and water-loss reducer play water conservation, improve storage and workability,
Typically use cellulose family.Antifreeze is mainly to improve the bin stability of putty at low temperature, slipping agent and water reducer etc. one
As be used in high-grade putty, improve the workability of putty.
Powder of lacquer putty for use on packaging storage convenient transportation, job site is added into water and uniformly stirred direct construction.Existing powder of lacquer putty for use on
Freedom from cracking, non-scale during leading indicator, do not fall off, there is certain hardness and water resistance.However, under wet weather, wall
Face moisture-sensitive, it is of long duration after breed bacteria, cause metope mouldy, influence that metope is attractive in appearance and Environmental Health, but have in the market
There is the powder of lacquer putty for use on of antibacterial functions still to be rare, the anti-microbial property retention time of existing antibacterial mastic powder is shorter.
With the development of the society, functional requirement of the people to powder of lacquer putty for use on also gradually steps up, in addition in general requirement, also need
Consider the function of bacteriostasis antibiosis.Therefore, there is an urgent need to a kind of powder of lacquer putty for use on of antibacterial functions.
