Abstract
The invention discloses novel antibacterial putty powder. The novel antibacterial putty powder comprises the following components: ground calcium carbonate, talcum powder, calcium-magnesium powder, modified starch, hydroxypropyl methyl cellulose, polymethylacrylic acid N,N-dimethylamino ethyl ester, an inorganic silver based antibacterial agent and a dispersing agent. In a use process, polymethylacrylic acid N,N-dimethylamino ethyl ester is in a swelling state after being dissolved in water, is capable of packaging silver ions in the inorganic silver based antibacterial agent and is slowly released; the putty powder is environmentally friendly, has long-term antibacterial performance and is capable of maintaining the beauty of a wall surface and the environmental health.
Description
Technical field
The present invention relates to building material technical field, particularly a kind of novel antibacterial putty powder.
Background technology
Before painting class construction during putty powder, carry out the surperficial flat powder material of pretreated one to construction surface, main purpose is filled the space of construction surface and corrects the curve deviation of construction surface, lays a solid foundation for obtaining even, level and smooth lacquer painting.
Putty is generally made up of base-material, filler, water and auxiliary agent etc.
Base-material, also claims binding agent, is the most critical component of putty, mainly plays the various effects such as bonding.The most frequently used binding agent of putty is cement and organic polymer, organic polymer have again emulsion and latex powder point.Cement is good, the durable and rational binding agent of cost performance of cohesiveness, but tensile strength and splitting resistance poor.Organic polymer to its modification and toughness reinforcing, thus can improve putty performance.
Filler mainly plays filling effect, and conventional has calcium carbonate, talcum powder and quartz sand etc.Should notice that the collocation of filler fineness uses.
Auxiliary agent has thickening material, water-holding agent etc.Thickening material and water-holding agent play water conservation, improve storage and workability, generally use cellulose family.Antifreezing agent mainly improves putty package stability at low temperatures, and surface slip agent and water reducer etc. are generally used in high-grade putty, improves the workability of putty.
Putty powder packaging stores convenient transportation, and working-yard adds water and stirs and can directly construct.Freedom from cracking, non-scale during the leading indicator of existing putty powder, not come off, there is certain hardness and water tolerance.But, under wet weather, metope moisture-sensitive, rear breed bacteria of long duration, causes metope mouldy, affects the attractive in appearance and Environmental Health of metope, but have the putty powder of antibacterial in the market still for rare, the anti-microbial property hold-time of the antibacterial mastic powder of existence is shorter.
Along with the progress of society, the functional requirement of people to putty powder also improves gradually, except general requirement, also needs the function considering bacteriostasis antibiosis.Therefore, in the urgent need to a kind of putty powder of antibacterial.
