Abstract
The invention relates to a softwood sealing washer and a production method thereof, and belongs to the technical field of softwood product production. Currently, the categories of the main forms of the domestic sealing washer product comprise a paper shell sealing washer, a rubber sealing washer, a softwood rubber sealing cushion and the like. By the softwood sealing washer and the production method for the softwood sealing washer, even if softwood particles are glued by a rubber gasoline solution, the softwood particles are subjected to vulcanization press cutting so as to form the softwood sealing washer.
Description
(1) technical field
A kind of cork gasket circle disclosed by the invention belongs to the cork article production technical field.
(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.In the cork article production technical field, the used glue of bonding granulated cork is Polyurethane glue at home.
(3) summary of the invention
A kind of cork gasket circle involved in the present invention, sealing packing ring are by the chemical materials of granulated cork and oil resisting rubber prescription structure and through sulfuration and cut open the technique such as crush-cutting and make.
1. the chemical materials of oil resisting rubber prescription is (weight part):
(1) paracril (content of vinyl cyanide is 40%) 50
(2) the 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
The sulfuration and cut open crush-cutting technique and finished by following steps:
A. the diameter of selecting particle is that 0.5～1.00mm, unit weight are that the granulated cork of 50～65g/L is major ingredient;
B. with industrial chemicals with opening rubber mixing machine mixing one-tenth film, put into the gasoline stirrer after shredding with scissors, and add the solvent gas and oil and stir, until oddments dissolves fully, make oil resisting rubber gasoline solution;
C.. the granulated cork of selecting is put into the cork stirrer with the oil resisting rubber gasoline solution of making and stir 10min; Make granulated cork and oil resisting rubber gasoline solution evenly and fully contact and covering;
D. start vacuum fan, extract and be transported to the industrial naptha gas of volatilization in stirrer out the baker burning.
E. drying the granulated cork that is covered with industrial chemicals put under the condition that iron die box intrinsic pressure is 10MPa and to put into baker after the compacting sealing and heat, make the temperature of iron die box in the environment of 110～130 degree Celsius, vulcanize 2h, then the airing 24h that comes out of the stove, breakdown iron die box namely gets slab dust cork.
F. slab dust cork is opened the cork sheet that cuts open into certain specification thickness with splitting machine.
G. there is the forming press of the gasket mould of certain model and specification the cork sheet crush-cutting to be become the cork gasket circle of certain model and specification with device.
(4) description of drawings
Accompanying drawing is the cork gasket coil structures view made from the inventive method, wherein:
1 is granulated cork.
2 chemical materialss for the oil resisting rubber prescription.
(5) embodiment
Son is described further technical scheme of the present invention by the following examples:
