Abstract
The present invention relates to a kind of production method of cork gasket circle, belong to technical field of cork product production.The production method of a kind of cork gasket circle provided by the invention, namely uses rubber gasoline solution to carry out agglomerate cork particle, then the cork gasket circle cuing open the techniques such as crush-cutting through sulfuration and make.
Description
(1) technical field
A kind of cork gasket circle disclosed by the invention, belongs to technical field of cork product production.
(2) background technology
At present, domestic seal washer product principal mode kind has paper shell seal washer, rubber gasket and cork rubber seal cushion circle etc.At home in technical field of cork product production, the glue bonding granulated cork used is Polyurethane glue.
(3) summary of the invention
A kind of cork gasket circle involved in the present invention, sealing packing ring to be constructed by the chemical materials of granulated cork and oil resisting rubber formula and through sulfuration and cut open the techniques such as crush-cutting and make.
1. the chemical materials of oil resisting rubber formula is (weight part):
(1) paracril (content of vinyl cyanide is 40%) 50
(2) high abrasion carbon black 70
(3) captax 0.2
(4) stearic acid 2
(5) antioxidant D 2
(6) altax 1
(7) zinc oxide 50
(8) dioctyl sebacate 25
(9) natural rubber 50
(10) sulphur 1.7
2.120 number industrial naptha
3. sulfuration and cut open crush-cutting technique and completed by following steps:
A. the granulated cork that the diameter of particle is 0.5 ~ 1.00mm, unit weight is 50 ~ 65g/L is selected to be major ingredient;
B. by mixing for industrial chemicals opening rubber mixing machine one-tenth film, after shredding with scissors, put into gasoline stirrer, and add the stirring of solvent gas and oil, until oddments dissolves completely, make oil resisting rubber gasoline solution;
C.. the granulated cork selected is put into cork stirrer with the oil resisting rubber gasoline solution made and stir 10min; Make granulated cork and oil resisting rubber gasoline solution evenly and fully contact and cover;
D. start vacuum fan, the industrial naptha gas of volatilization in stirrer is extracted out and is transported to baker burning.
E. it is put into baker after compacting sealing under the condition of 10MPa to heat that the granulated cork being covered with industrial chemicals drying puts iron die box intrinsic pressure into, make the temperature of iron die box sulfuration 2h in the environment of 110 ~ 130 degree Celsius, then come out of the stove airing 24h, and namely breakdown iron die box obtains slab dust cork.
F. with splitting machine, slab dust cork is opened the cork sheet cuing open into certain specification thickness.
G. the forming press of certain model and the gasket mould of specification is had cork sheet crush-cutting to be become the cork gasket circle of certain model and specification with device.
(4) accompanying drawing explanation
Fig. 1 is the cork gasket coil structures view manufactured by the inventive method, wherein:
1 is granulated cork.
2 is the chemical materials that oil resisting rubber is filled a prescription.
(5) embodiment
