Further, the injection rate of the Silica hydrogel is the 50%~80% of the inner chamber capacity of silica gel housing 1.
Further, the portion of the handle 2 is made of plastic cement.
Further, the portion of the handle 2 is hollow annular.
Further, the silica gel housing 1 is in heart.
(3) beneficial effect
The present invention is compared to prior art, and it has the advantages that：Silica hydrogel can be in -65~200 DEG C of temperature models
Interior long-term holding elasticity is enclosed, it has excellent chemical stability；Its is water-fast, resistance to ozone, weather-resistant, hydrophobic, protection against the tide,
It is shockproof, corrosion-free, and with physiological inertia, it is nontoxic, tasteless, be easy to perfusion, can deep vulcanization, linear shrinkage ratio it is low, simple to operate
The advantages of；The present invention is soft, comfortable using the characteristic of silica gel and Silica hydrogel, in good taste close to the skin feel of people, and has resistance to
Mill property, not cracky, and as will not be also caused Silica hydrogel to flow out after sharp thing (such as pin) puncture silica gel housing allows baby
It is safer when using this product, trust.
Brief description of the drawings
Fig. 1 is the process chart of the manufacturing process of the silica gel gutta-percha of the present invention.
Fig. 2 is the structural representation of the silica gel gutta-percha of the present invention.
Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Following reality
Applying example is used to illustrate the present invention, but is not limited to the scope of the present invention.
Silica gel material, is first filled into mould and is made with injection port 3 by the manufacturing process of silica gel gutta-percha as shown in Figure 1
Silica gel housing 1, then vulcanize silica gel housing 1 under 70 DEG C of -90 DEG C of environment temperatures.Silica hydrogel is made again：
A) measure：Precise A, B component should observe A: B=1: 1 (weight)；
B) glue is mixed：By A, the full and uniform mixing of B component；
C) deaeration：Well mixed sizing material is placed in deaeration in vacuum tank；
D) pour into a mould：The sizing material for having taken off bubble is filled into silica gel housing 1 and then completed potting operation by injection port 3；
E) vulcanize：The complete silica gel housing 1 of embedding is vulcanized in 70 DEG C of -90 DEG C of left at ambient temperature.
The injection rate of Silica hydrogel is the 50%~80% of the inner chamber capacity of silica gel housing 1.The whole of silica gel gutta-percha can so be ensured
Body comfortableness and flexibility.
The silica gel gutta-percha of utilization as shown in Figure 2 technique manufacture, it includes gutta-percha body and portion of the handle 2, gutta-percha sheet
Body includes the Silica hydrogel of silica gel housing 1 and injection silica gel housing 1 with injection port 3.Injection port 3 is located at gutta-percha body and hand-held
The junction of part 2, injection port is concealed design.Portion of the handle 2 is made of plastic cement.Portion of the handle 2 is hollow annular.Silicon
Glue housing 1 is in heart.The silica gel gutta-percha shape is lovely, and the whole outer surface of silica gel housing is a smooth curved surface, makes the product
It will not be produced when being placed on baby in the mouth such as the sense of discomfort of the prominent grain Molars rod of band etc.And the product chews very flexible, fills out
Thing is filled for Silica hydrogel, has more comfortable mouthfeel as the Molars rod of filler compared to water or other liquid.
Silica gel has good biocompatibility, it is nonirritant to tissue, non-toxic, without allergic reaction, body arrange
Different reaction is few；With good physicochemical property, with that in body fluid and tissue contact process its can be kept original elastic and soft
Softness, is not degraded, and is a kind of inert substance of quite stable.Energy high temperature resistant, can be sterilized, and machine-shaping is convenient.
Silica hydrogel can keep elasticity for a long time in -65~200 DEG C of temperature ranges, and it has excellent chemical stability；
Its is water-fast, resistance to ozone, weather-resistant, hydrophobic, protection against the tide, shockproof, corrosion-free, and with physiological inertia, it is nontoxic, tasteless, be easy to
Perfusion, the vulcanization of energy deep, linear shrinkage ratio are low.
The present invention is soft, comfortable using the characteristic of silica gel and Silica hydrogel, in good taste close to the skin feel of people, and has
Wearability, cracky, will not cause Silica hydrogel to flow out yet, allow baby to exist after piercing through silica gel housing such as sharp thing (such as pin)
It is safer during using this product, trust.
Certainly, it the above is only the concrete application example of the present invention, protection scope of the present invention be not limited in any way.Remove
