Background technology
Hollow microsphere is a material colony with special construction, and it is meant the spherical shell type material of one type of size in nanometer to several millimeters and inner hollow.Compare with unidimensional sphere material, hollow microsphere has that density is low, the remarkable advantage of economical with materials.In addition, the hollow microsphere hollow structure inside makes it have performances such as unique mechanical, acoustics, optics.In recent years, be on the increase along with what hollow microsphere was studied, the structure of hollow microsphere and the particularity of performance more and more cause people's attention.
Encapsulant draws and is meant and can bears the seam displacement to reach airtight, watertight purpose and embed the material in the building joint that sealing member material has metal material, like aluminium, lead, indium, stainless steel etc., nonmetallic materials such as rubber, plastics, pottery, graphite etc. is arranged also.But using maximum is the rubber-like elastomeric material; Successively be applied to various industries such as automobile, door and window, rack, refrigerator, container; According to the requirement of different industries, products such as distinctive weather strip for automobile, mechanical seal bar, door and window sealing strip have successively been developed.In general, adopt encapsulant can be reduced to the energy of regulating the required consumption of indoor temperature, thus, the heat insulation and soundproof effect of encapsulant will influence heat insulation, the soundproof effect of building to a great extent; In addition, sealing strip unavoidably will touch the bacterium in the environment in storage and application process, and the quick breeding of bacterium can make the mouldy and generation peculiar smell of sealing strip, influences serviceability.
Summary of the invention
The object of the invention just provides a kind of antibiotic hollow microsphere, has the effect of broad-spectrum sterilization, is applied to encapsulant, as is added in the polyurethane sealing strip, makes the polyurethane sealing strip have long-acting antibacterial functions, improves the service life of encapsulant.
Another purpose of the present invention is to provide the preparation method of antibiotic hollow microsphere.
Another purpose of the present invention is to provide the application of antibiotic hollow microsphere.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of antibiotic hollow microsphere, comprise hollow sphere, and the outer wall of said hollow sphere is with nano silver particles.
Further, said nano silver particles sticks to the outer wall of said hollow sphere through coupling agent.
Further, said coupling agent is to contain amino silane coupling agent.
Further, said hollow sphere is processed by polymer, inorganic matter or polymer and the compound material of inorganic matter.
According to another purpose of the present invention, a kind of preparation method of antibiotic hollow microsphere comprises the steps:
1) coupling agent is hydrolyzed;
2) hollow microsphere is immersed in the hydrolyzate of coupling agent;
The suspension that 3) will contain nano silver particles is coated on the hollow microsphere surface through coupling agent treatment.
Further, said coupling agent is to contain amino silane coupling agent.
Further, said hollow microsphere is the compound hollow microsphere of polymer hollow particles, inorganic hollow microballoon or polymer and inorganic matter.
According to another purpose of the present invention, the antibiotic hollow microsphere in the such scheme is applied in the encapsulant.
Further, in the sealing strip of polyurethane encapsulant cast or sealing ring, add described antibiotic hollow microsphere.
Beneficial effect of the present invention: nano silver particles has stronger broad-spectrum bactericidal action; In hollow microsphere, add nano silver particles and can be able to play sterilization, antibiotic effect; Hollow microsphere is compared with other solid materials, has less density, bigger surface area, can use as light filler; Particularly in the sealing strip of cast polyurethane; Add with behind the hollow microsphere of nano silver particles and give sealing strip long-acting antibacterial functions, can also improve the character of sealing strip, improve sound insulation, the heat-proof quality of sealing strip.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further explanation:
Fig. 1 is a structural representation of the present invention.
Embodiment
The present invention provides a kind of antibiotic hollow microsphere, comprises hollow sphere, and the outer wall of said hollow sphere is with nano silver particles.Nano silver particles has stronger broad-spectrum bactericidal action, in hollow microsphere, adds nano silver particles and can be able to play sterilization, antibiotic effect.
The technical scheme of the embodiment of the invention is made an explanation and explain below in conjunction with the accompanying drawing of present embodiment, but following embodiment is the preferred embodiments of the present invention only, is not whole.Based on the embodiment in the embodiment, those skilled in the art belong to protection scope of the present invention at following other embodiment that obtains of the prerequisite of not making creative work.
With reference to Fig. 1, antibiotic hollow microsphere comprises hollow sphere, and the outer wall of said hollow sphere is with nano silver particles.Hollow sphere inside can be gas, also can be encapsulation small-molecule substance such as easy volatile solvent such as water, hydro carbons.Hollow sphere can be processed by polymer, inorganic matter or polymeric layer and inorganic layer composite.Polymer can be polyethylene, polypropylene, polyvinyl chloride or polystyrene etc., and inorganic matter can be calcium carbonate, barium sulfate, titanium oxide etc.
Preparation method as antibiotic hollow microsphere among the present invention; The preparation method of hollow microsphere itself has belonged to prior art; So no longer detail; The present invention adheres to nano silver particles and includes but not limited to following method on hollow microsphere: utilize coupling agent that nano silver particles is sticked to the outer wall of hollow sphere, concrete operations are following: select for use to contain amino silane coupling agent and mix with water, be hydrolyzed; On silane coupled agent molecule, form hydroxyl; Impregnated polymer microballoon then, hydroxyl in the silane coupler and hollow sphere surface form strong interactions such as chemical bond or hydrogen bond, and the suspension that will contain nano silver particles again is coated on the hollow sphere of coupling agent treatment; Amino and remaining hydroxyl in nano silver particles and the silane coupler forms stronger interaction, thereby between nano silver particles and hollow sphere, forms stronger bonding through this bridge block of coupling agent.Utilize adhesive method with nano silver particles attached on the hollow sphere, simple to operate, cost is low, in addition, silane coupler is that as the action principle of tackifier itself has two kinds of groups; A kind of group can combine with the sticking framework material of quilt; Another kind of group then can combine with macromolecular material or bonding agent, thereby forms powerful higher chemical bond at bonding interface, has improved adhesive strength greatly.To add in the sealing strip through the hollow microsphere that silane coupler adheres to nano silver particles, can improve performances such as the adhesion strength of sealing strip material, water-fast, weather.
