Abstract
The invention relates to a manufacturing method of a fluororubber cup, in particular to a manufacturing method of the fluororubber cup. The manufacturing method of the fluororubber cup includes the following steps that firstly, mixed fluororubber subjected to remilling and thin-passing is sheared into fragments through a shear, the fragments are dissolved in an ethyl acetate solvent, and original fluororubber pulp is prepared; secondly, sand blasting is conducted on a metal framework, and the metal framework is washed through gasoline and acetone and aired; thirdly, coating the metal framework with adhesives, a brush is dipped into the original fluororubber pulp and sprays the original fluororubber pulp on the metal framework coated with the adhesives after solvent in the adhesives are evaporated, and the metal framework is placed at the room temperature so that the ethyl acetate solvent can be evaporated; and fourthly, the metal framework coated with the adhesives and the original fluororubber pulp and a fluororubber material are placed in a mode together to be vulcanized, and the rubber cup is manufactured. The manufacturing method of the fluororubber cup overcomes the defect that the fluororubber cup is prone to the degumming phenomenon, and therefore the percent of pass of the fluororubber cup is increased and reliability of the working quality is improved.
Description
Technical field
The present invention relates to a kind of manufacture method of part, be specifically related to a kind of manufacture method of fluorubber leather cup.
Background technology
At present, fluorubber leather cup manufacturing process adopts usually: first to metallic framework blasting treatment, again with gasoline, acetone cleaning airing, then adhesive coating, after at room temperature placement certain hour makes solvent fully volatilize, again ready fluoroelastomer glue stock and metallic framework are loaded in mould for one week, carry out sulfuration by the sulfuration process of regulation.
Adopt this common fluorubber leather cup manufacturing process, easily there is coming unstuck between metallic framework and rubber in the leather cup produced, cause adhesive effect poor, qualification rate is low, generally be only about 70%, in addition, due to the inspection of adhesive effect between metallic framework and fluorubber, by testing to the rubber tapping of rubber cup the destructive testing carried out, therefore the bonding quality inspection of fluorubber leather cup is controlled, can only take sampled version, this just reduces the reliability of fluorubber leather cup work quality to a great extent.
Summary of the invention
The object of this invention is to provide a kind of manufacture method of fluorubber leather cup, solve the drawback that degumming phenomenon easily appears in fluorubber leather cup, thus improve the reliability of fluorubber leather cup qualification rate and work quality.
The present invention is a kind of manufacture method of fluorubber leather cup, and the method step is as follows: first the mixing fluorubber scissors through back mixing, thin-pass is cut into fragment, is dissolved in ethyl acetate solvent, and preparation becomes fluorubber virgin rubber slurry; Thereafter blasting treatment is carried out to metallic framework, dry with gasoline, acetone cleaning; Then adhesive coating on metallic framework, after the solvent volatilization in adhesive, dips in fluorubber virgin rubber slurry with hairbrush, being coated on oneself metallic framework through coating adhesive, at room temperature placing and ethyl acetate solvent is volatilized; Again the metallic framework coating adhesive and fluorubber virgin rubber slurry is put into mould together with fluoroelastomer glue stock and carry out sulfuration, make fluorubber leather cup.
The manufacture method of described fluorubber leather cup, its preferred version is, in fluorubber virgin rubber slurry, mass ratio is, fluorubber: ethyl acetate=1:4 ~ 6.
Beneficial effect of the present invention is: present invention improves adhesive effect between metallic framework and rubber, reduce coming unstuck between fluorubber leather cup metallic framework and rubber, improve adhesive effect, improve qualification rate, reduce waste product and material, the waste etc. in man-hour, reduce manufacturing cost.
Detailed description of the invention
Embodiment
1) material therefor: metallic framework, fluorubber, adhesive, gasoline, acetone, ethyl acetate.
2) production equipment instrument: vulcanizing press, rubber mixing machine, electric drying oven with forced convection, sky equality.
3) operate:
1. virgin rubber slurry is prepared
Take 100g through back mixing, fluoroelastomer glue stock that thin-pass is good, be cut into fragment with scissors, be dissolved in the ethyl acetate solvent of 500g, fully stir with glass bar, until it is stand-by to build lid evenly.
2. the surface treatment of metallic framework and the coating of adhesive
With No. 120 gasoline by clean for metallic framework surface clean, dry rear sandblasting, use No. 120 gasoline, acetone clean metal skeleton again, make to residue in sand grains on metallic framework and dirt is thoroughly removed, adhesive coating after placement 30min, at room temperature place 30min again, the solvent in adhesive is volatilized.
3. virgin rubber slurry is applied
Dip in the virgin rubber slurry prepared with hairbrush, being coated on oneself metallic framework through coating adhesive, at room temperature placing 30min, ethyl acetate solvent is volatilized.
4. sulfuration
The metallic framework coating virgin rubber slurry is put into mould with the fluoroelastomer glue stock sheared, by rubber vulcanization technological parameter, vulcanizing press carries out one step cure, i.e. compression molding, then carry out post vulcanization in electric drying oven with forced convection.
Claims (2)
1. a manufacture method for fluorubber leather cup, is characterized in that, the method step is as follows: first the mixing fluorubber scissors through back mixing, thin-pass is cut into fragment, is dissolved in ethyl acetate solvent, and preparation becomes fluorubber virgin rubber slurry; Thereafter blasting treatment is carried out to metallic framework, dry with gasoline, acetone cleaning; Then adhesive coating on metallic framework, after the solvent volatilization in adhesive, dips in fluorubber virgin rubber slurry with hairbrush, being coated on oneself metallic framework through coating adhesive, at room temperature placing and ethyl acetate solvent is volatilized; Again the metallic framework coating adhesive and fluorubber virgin rubber slurry is put into mould together with fluoroelastomer glue stock and carry out sulfuration, make fluorubber leather cup.
2. the manufacture method of fluorubber leather cup according to claim 1, is characterized in that, in fluorubber virgin rubber slurry, mass ratio is, fluorubber: ethyl acetate=1:4 ~ 6.
