The invention relates to a powder injection rubber sealing ring production method, and belongs to the technical field of filtrator rubber sealing rings. The production method comprises: weighing a main material and an auxiliary material, mixing the materials, molding, demolding and cutting, wherein the main material comprises, by weight, 28-36 parts of acrylonitrile-butadiene rubber 2865, and the auxiliary material comprises, by weight, 10-18 parts of carbon black 330, 10-18 parts of semi-reinforcing purpose furnace black, 1-6 parts of dioctyl phthalate, 0.35-0.65 part of zinc oxide, 0.02-0.05 part of sulfur, 0.2-0.7 part of hard acid ester, 0.3-0.7 part of an anti-aging agent 4010NA, 0.3-0.7 part of an anti-aging agent RD, 0.15-0.3 part of an accelerator T.T.C, 2-7 parts of calcium carbonate, 0.8-1.2 parts of EN-100, and 0.15-0.25 part of an accelerator DM. The powder injection rubber sealing ring production method has characteristics of wide adaptability, controllable blooming form, low influence on the sealing ring, high production efficiency, short production cycle, and low production cost.
Description
Technical field
The invention belongs to the rubber sealing ring of filter cleaner technical field, refer in particular to a kind of production method of the class rubber seal of dusting.
Background technology
Bloom is more common phenomenon in rubber, and the reason more complicated that causes prevents that the rubber surface bloom can be by adjusting sizing compound formula, improve technological process, improving storage requirement etc. by way of realizing.Rubber has dividing of unvulcanized rubber (hereinafter referred to as sizing material) and vulcanized rubber (hereinafter referred to as goods), and the rubber bloom just comprises sizing material surface bloom and product surface bloom.Bloom (bloom) is that the liquid or solid Synergist S-421 95 is by the phenomenon of rubber internal migration to rubber surface.As seen the inner Synergist S-421 95 of rubber is separated out, and has just formed bloom.Form to the rubber bloom is summed up, and substantially is divided into three kinds.Namely dust, wax spray, oil spout (also claiming to ooze out), in the prior art, can not control the bloom kind of rubber in the production of sealing-ring, can be which kind of bloom form be can not determine for the rubber of producing, larger for the performance impact of sealing-ring.
Summary of the invention
The purpose of this invention is to provide a kind of wide adaptability, can control the production method of the class rubber seal of dusting of its bloom form.
The object of the present invention is achieved like this:
A kind of production method of the class rubber seal of dusting, it comprises the steps:
(1) weighing: take by weighing the raw material of making rubber sealing ring of filter cleaner;
(2) batch mixing: the raw material that step (1) is taken by weighing mixes;
(3) moulding: the mixed raw material of step (2) is inserted sulfidization molding in the tubular die of the injection moulding machine of setting caliber;
(4) demoulding: obtain having the rubber hose of setting caliber;
(5) cutting: the rubber hose that step (4) is made by the setting height of rubber sealing ring of filter cleaner cuts into the rubber sealing ring of filter cleaner of setting height and internal-and external diameter.
Above-mentioned raw material includes major ingredient and auxiliary material.
It is characterized in that: above-mentioned major ingredient comprises: described major ingredient comprises: the nitrile rubber 2865 of 28～36 weight parts; Described auxiliary material comprises: the carbon black 330 of 10～18 weight parts, half reinforcement of 10～18 weight parts, the dioctyl ester of 1～6 weight part, 0.35 the zinc oxide of～0.65 weight part, 0.02 the sulphur of～0.05 weight part, 0.2 the hard acid ester of～0.7 weight part, 0.3 the antioxidant 4010NA of～0.7 weight part, 0.3 the anti-aging agent RD of～0.7 weight part, 0.15 the promotor T.T.C of～0.3 weight part, the calcium carbonate of 2～7 weight parts, 0.8 the altax of the EN-100 of～1.2 weight parts and 0.15～0.25 weight part.
Major ingredient and auxiliary material are put into mill, fully mixing.
Above-mentioned cutting is that rubber hose is placed on the rubber sealing ring of filter cleaner that cuts into setting height on the numerical control cutting equipment with cutter.
The present invention compared to existing technology outstanding advantage is: wide adaptability, can control its bloom form, less on the impact of sealing-ring, production efficiency is high, with short production cycle, production product size deviation is little, conservation, production cost are low.
