Abstract
A sealing gasket for a bottle cover belongs to the technical field of bottle covers. The sealing gasket comprises a silicon rubber gasket body and is characterized in that the silicon rubber gasket body is covered with a teflon film. The sealing gasket for the bottle cover is formed by compositing teflon and silicon rubber and integrates advantages of the teflon and the silicon rubber. On one hand, the teflon surface which contacts with chemical reagents in a glass bottle can not be corroded, and on the other hand, the gasket has good elasticity, so that good tightness is achieved when the cover is tightened, and chemical reagents in the glass bottle can not leak.
Description
Technical field
The utility model belongs to the bottle cap technical field, is specially a kind of bottle cap sealing pad.
Background technology
Silaatic has excellent performances such as resistance to effect of heat, resistance to cold, dielectricity, anti-ozone and anti-atmospheric aging, and the outstanding performance of silaatic is to use temperature broad, can be in-60 ℃ (or lower temperature) to+250 ℃ (or higher temperature) long-term use down.It has good elasticity simultaneously, is fit to pricker and sealing.
Polytetrafluoroethylene generally is called non-sticking lining, is a kind of artificial synthesized polymer material that has used fluorine to replace all hydrogen atoms in the poly-vinyl.This material has the characteristics of antiacid alkali resistant, anti-various organic solvents, is dissolved in all solvents hardly.Simultaneously, polytetrafluoroethylene has high temperature resistant, and inadhesive characteristics are surface tension minimum in the solid material, do not adhere to any material.Because the technical characterstic of these two kinds of products self, therefore present domestic technology does not also combine these two kinds of products the case of use.
The utility model content
To the problems referred to above that exist in the prior art; The purpose of the utility model is to design the technical scheme that a kind of bottle cap sealing pad is provided; Adopt polytetrafluoroethylene and two kinds of compound processing of material of silaatic; Advantage with two kinds of products, its good springiness, not perishable is applicable to that chemical products stores on the glass cap of usefulness.
Described a kind of bottle cap sealing pad comprises silicone rubber pad, it is characterized in that covering on the silicone rubber pad polytetrafluoroethylene film layer is set.
Described a kind of bottle cap sealing pad, the thickness that it is characterized in that said silicone rubber pad is 1-3mm.
Described a kind of bottle cap sealing pad, the thickness that it is characterized in that said silicone rubber pad is 1.5-2.5mm.
Described a kind of bottle cap sealing pad, the thickness that it is characterized in that said polytetrafluoroethylene film layer is 0.05-0.5mm.
Described a kind of bottle cap sealing pad, the thickness that it is characterized in that said polytetrafluoroethylene film layer is 0.1-0.2mm.
Above-mentioned a kind of bottle cap sealing pad adopts polytetrafluoroethylene and two kinds of compound processing of material of silaatic, and it has combined both advantages separately, guarantees that the polytetrafluoroethylene face touches the chemical reagent that is stored in the glass bottle and can not corrode on the one hand; On the one hand, this pad has good elasticity again, makes when lid is tightened, and has played good leak tightness, exists the chemical reagent in the glass bottle can not reveal in addition.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1-silicone rubber pad, 2-polytetrafluoroethylene film layer.
The specific embodiment
Below in conjunction with Figure of description the utility model is described further.
As shown in the figure, this bottle cap sealing pad comprises silicone rubber pad 1, covers on the silicone rubber pad 1 polytetrafluoroethylene film layer 2 is set.The thickness of said silicone rubber pad 1 is 1-3mm, preferred 1.5-2.5mm.The thickness of said polytetrafluoroethylene film layer 2 is 0.05-0.5mm, preferred 0.1-0.2mm.Two kinds of material combination process of polytetrafluoroethylene and silaatic are described below: through to the surface of PTFE film material through how receiving after the chemical treatment, increase its polarity and surface tension, thereby obtain activating surface, make itself and the silaatic can be bonding; Then that prior sulphurization is good silaatic sheet material is pressed onto together under certain temperature and pressure, forms polytetrafluoroethylene/silaatic sheet material, through die-cutting process, cuts out the pad size of wanting then; Polytetrafluoroethylene and silaatic through this technology after bonding are difficult for peeling off.
When using this bottle cap sealing pad; Silicone rubber pad 1 this face is inner towards bottle cap, and polytetrafluoroethylene film layer 2 this face are towards this one side of contact liq, and it has combined both advantages separately; One side guarantees that the surface of polytetrafluoroethylene film layer 2 touches the chemical reagent that is stored in the glass bottle and can not corrode; On the one hand, the silicone rubber pad 1 of this pad has had good elasticity again, makes when lid is tightened in addition; Play good leak tightness, existed the chemical reagent in the glass bottle can not reveal.
Claims (5)
