Description
Technical field
Formula that the present invention relates to rubber item and preparation method thereof field, is specifically related to slush pump piston cup and preparation method thereof.
Background technology
Slush pump is equipment conventional in field drilling, in conventional normal circulation probing, it is by earth's surface flushing medium--clear water, mud or polymer flush fluid are under pressure, through the bottom of high pressure hose, water tap and drill string central hole direct sending drill bit, to reach cooling drill bit, the landwaste cut removed and is transported to the object on earth's surface.Conventional slush pump is piston-type or plunger tpe, and piston or plunger move reciprocatingly in pumping cylinder, to realize the object of force feed and circulating flushing washing lotion.When piston moves reciprocatingly in cylinder body, leather cup is with piston to-and-fro movement play sealing function in mud, crude oil medium, and it needs to have the performances such as good wear resistance, high pressure resistant, high temperature resistant low temperature, corrosion-resistant, anti tear.The corrosion resistance of existing rubber cup in oil-base mud is more weak, and be easily subject to the corrosion of heat, oxygen and copper manganese poisonous metal, in addition, its tear strength is poor, can not meet the requirement of modern drilling technique.
Summary of the invention
Object of the present invention is just to provide a kind of slush pump piston cup and preparation method thereof, by the rubber cup of formula preparation of the present invention, there is the performances such as good high pressure resistant, high temperature resistant low temperature, corrosion-resistant, anti tear, and can the corrosion of effectively protective hot, oxygen and copper manganese poisonous metal.
For achieving the above object, technical scheme of the present invention is: slush pump piston cup, count by weight, its raw material consists of: 12 ~ 18 parts of paracrils, 0.5 ~ 1.0 part of zinc oxide, 0.1 ~ 0.2 part of stearic acid, 0.15 ~ 0.3 part of captax, 0.05 ~ 0.2 part of promotor TT, 0.2 ~ 0.5 part of oligomer ester, 0.2 ~ 0.5 part of coumarone indene resin, 0.1 ~ 0.2 part of antioxidant 4010NA, 0.1 ~ 0.2 part of anti-aging agent RD, 0.05 ~ 0.2 part of antioxidant H B-5,10 ~ 15 parts of high wear-resistant carbon blacks, 1.5 ~ 3.0 parts of semi-reinforcing hydrocarbon blacks and 0.1 ~ 0.2 part of sulphur.
The preparation method of described slush pump piston cup, comprises the steps:
(1), by paracril bale splitter be cut into bulk, be placed in mill and carry out thin-pass and to plasticate discharging after 5 times, and place 8 ~ 11h;
(2), the sizing material after plasticating through thin-pass is placed in Banbury mixer, and add zinc oxide, stearic acid, captax, promotor TT, oligomer ester, coumarone indene resin, antioxidant 4010NA, anti-aging agent RD, antioxidant H B-5, high wear-resistant carbon black and semi-reinforcing hydrocarbon black and mix, carry out mixing 10min;
(3), by complete mixing after rubber unvulcanizate send into mill, and add sulphur and carry out slice after refining, slice thickness 5mm, size 5cm × 100cm;
(4), the film after step (3) refining is carried out the first one-step forming of piston cup;
(5), carry out in the die cavity that the piston cup of the first one-step forming of step (4) is placed in piston cup mould shaping, and to control shaping temperature with vulcanizing press be 150 DEG C, and pressure is 5Mpa, and the time is 30min, and after cooling, the demoulding gets product.
The model that described paracril adopts is JSR220S and 3305, and in both, the content of vinyl cyanide is respectively 42% and 33%, and both weight ratios are 1:4.
Antioxidant 4010NA, its chemical name is: N-sec.-propyl-N'-diphenyl-para-phenylene diamine; Anti-aging agent RD, its chemical name is: 2,2,4-trimethylammonium-1,2-dihyaroquinoline polymer; Antioxidant H B-5, its chemical name is: N-(4-aniiinophenyl) maleimide; Captax, its chemical name is: 2-thiol benzothiazole; Promotor TT, its chemical name is: tetramethyl-thiuram disulfide.
Beneficial effect: piston cup of the present invention adopts paracril to be main body sizing material, add promoting agent zinc oxide and stearic acid, captax and promotor TT, softening agent oligomer ester and solid coumarone resin, antioxidant 4010NA, RD and HB-5, reinforcing filler high wear-resistant carbon black and semi-reinforcing hydrocarbon black, vulcanizing agent sulphur.Wherein, zinc oxide forms zinc soap under stearic acid coordinates, and makes it to be easy to be dissolved in sizing material, a kind of binding substances is formed with captax and promotor TT, make promotor more active, can activate sulphur and form a kind of very strong vulcanizing agent, the glue improving vulcanized rubber connects density and heat aging property.Captax and promotor TT can promote the reaction between sizing material and vulcanizing agent, improve vulcanization rate, reduce curing temperature, improve the elongation of sizing material, tensile strength and tear strength simultaneously.Softening agent oligomer ester can improve the bond strength of sizing material, increases the hardness of sizing material, tensile strength and wear resistance, and can shorten mixing time, enhance productivity.Solid coumarone resin contributes to carbon black dispersion and can improve sizing material extruding the processing performances such as calendering and tackiness, and energy dissolution of sulphur is uniformly dispersed and prevents incipient scorch, can also improve physical and mechanical properties and the ageing resistance of cross-linked rubber.Antioxidant 4010NA and anti-aging agent RD use, make sizing material can the corrosion of effectively protective hot, oxygen and copper manganese poisonous metal, and antioxidant H B-5 is in order to increase heat-resisting, the medium corrosion resistance energy of sizing material.Both high wear-resistant carbon black and semi-reinforcing hydrocarbon black combine hardness, intensity and the elasticity that can improve rubber item, and can improve the processing characteristics of sizing material, and improve the performance such as wear-resisting, tear-resistant, cold-resistant of goods, prolongation goods work-ing life.Vulcanizing agent sulphur has excellent snappiness, high strength and the performance such as ageing-resistant in order to make sizing material.
