Abstract
The invention provides a preparation method of an antibacterial silica gel toothbrush head. The method includes the following steps: 1, preparing antibacterial silica gel masterbatches from LSR silica gel and zirconium phosphate in a weight ratio of 99.5 to 0.5 through blending; 2, adding ethyl orthosilicate with the weight being 3% of that of LSR silica gel into silica gel dispersed materials to prepare toothbrush head raw materials through quick mixing; 3, coating the inner surface of a toothbrush head mold with a superfine silver layer with the weight being 1% of that of LSR silica gel; 4, injecting the toothbrush head raw materials prepared in step 2 in the mold treated in the step 3 in four stages for molding. The toothbrush head is good in elasticity, not like to hurt the mouth cavity, waterproof and antibacterial, and the outer layer of the silver layer also has a bactericidal function.
Description
Technical field
The present invention relates to a kind of antibacterial silica gel head toothbrushes and preparation method thereof.
Background technology
Toothbrush is the necessary article of daily life, all can be used daily, and traditional toothbrush adds nylon using the base of plastics
Bristle, improper use can cause the symptoms such as gingival hemorrhage, and the patient of some odontopathy, such as gingival atrophy, Root exposnre, make
With traditional nylon filament toothbrush, can not only take care of one's teeth, can also bring very big injury to gingiva；And toothbrush due to Jing it is normal
Contact water, easy breed bacteria, therefore it provides a kind of comfortable, energy antibacterial prevents the head toothbrushes of pathogen transmission necessary.
The content of the invention
Mentioned above to solve the problems, such as, the present invention provides a kind of antibacterial silica gel head toothbrushes and preparation method thereof.
The preparation method of the antibacterial silica gel head toothbrushes that the present invention is provided includes the steps：
Step 1：By LSR silica gel（Liquid）：Zirconium phosphate is with percentage by weight as 99.5:Antibacterial silica gel masterbatch is made after 0.5 fusion；
Liquid-state silicon gel（LSR silica gel）The brush of preparation has good elastic and waterproof and dampproof property, is particularly suitable for preparing brush, due to
Elasticity is good, and oral cavity will not be damaged, and its superior waterproof and dampproof performance, can more stop growing for antibacterial, meanwhile, it is also
The erosion of various chemical substances such as acid and alkali resistance, service life is also very long；The stronger acid of zirconium phosphate ability and certain basicity, surely
Qualitative and mechanical strength is very strong.
Step 2：The tetraethyl orthosilicate for adding LSR silica gel weights 3% is added in colloidal silica dispersion material, quick stir process system
Into brush raw material, tetraethyl orthosilicate is present as a kind of organic crosslinking agent, improves the intensity and elasticity of product；
Step 3：In the ultra-fine silver layer that the inner surface uniform application weight of head toothbrushes mould is LSR silica gel weights 1%, ultra-fine silver layer
It is to use particle mean size<0.5 μm of super fine silver powder uniform application is formed；
Step 4：The brush raw material prepared in step 2 is divided into into four-stage to be molded in the mould processed through step 3, is obtained
Described antibacterial silica gel head toothbrushes；
Four injection phases are as follows：
First paragraph：Temperature is 115 DEG C, and injection pressure is 85MPA, and injection moulding speed is 27mm3/ s, the time is 28s;
Second segment：Temperature is 115 DEG C, and injection pressure is 65 MPA, and injection moulding speed is 22 mm3/ s, the time is 30s;
3rd section：Temperature is 110 DEG C, and injection pressure is 45 MPA, and injection moulding speed is 18 mm3/ s, the time is 25s;
4th section：Temperature is 110 DEG C, and injection pressure is 28 MPA, and injection moulding speed is 5mm3/ s, the time is 15s.
Step 5：Cooling, the demoulding obtains a kind of antibacterial silica gel head toothbrushes.
Further, LSR silica gel and zirconium phosphate mix homogeneously are caused using supersound process in step 1, supersound process it is general
Rate is 1200W, and the frequency of supersound process is 60Khz, and the time is 5-12min.
Further, the quick stir process in step 2 is referred to positive silicon using omnipotent blender or planetary stirring machine
Acetoacetic ester and colloidal silica dispersion material stir 2min with 45rmp.
Further, described brush include silica gel main body and located at described silica gel body surfaces and and it is described
The main body integrated silver layer of silica gel.
The beneficial effects of the present invention is, the head toothbrushes that the present invention is provided, elasticity is good, it is not easy to injure oral cavity, and waterproof resists
Bacterium, the silver layer of outer layer also has the effect of sterilization.
Specific embodiment
This case is described further with reference to specific embodiment：
Step 1：By LSR silica gel：Zirconium phosphate is with percentage by weight as 99.5:0.5 causes LSR silica gel and phosphoric acid using supersound process
Zirconium merges, and the probability of supersound process is 1200W, and the frequency of supersound process is 60Khz, and the time is 5-12min, makes antibacterial silica gel
Masterbatch；
Step 2：The tetraethyl orthosilicate for adding LSR silica gel weights 3% is added in colloidal silica dispersion material, using omnipotent blender or row
Tetraethyl orthosilicate and colloidal silica dispersion material are made brush raw material by planetary blender with 45rmp stirring 2min, and tetraethyl orthosilicate is to make
For a kind of presence of organic crosslinking agent, the intensity and elasticity of product are improved；
Step 3：In the ultra-fine silver layer that the inner surface uniform application weight of head toothbrushes mould is LSR silica gel weights 1%, ultra-fine silver layer
It is to use particle mean size<0.5 μm of super fine silver powder uniform application is formed；
Step 4：The brush raw material prepared in step 2 is divided into into four-stage to be molded in the mould processed through step 3, is obtained
Described antibacterial silica gel head toothbrushes；
Four injection phases are as follows：
First paragraph：Temperature is 115 DEG C, and injection pressure is 85MPA, and injection moulding speed is 27mm3/ s, the time is 28s;
