Abstract
The invention discloses a kind of big primer of resistance to oiled boots of the injection molding for being not easy incipient scorch, calculate in parts by weight, including butadiene-styrene rubber 80, nitrile rubber 20, sulphur 2, captax 0.4 0.6, diphenylguanidine 0.1 0.3, altax 0.9 1.1, Vulcanization accelerator TMTD 0.1 0.2, zinc oxide 5, stearic acid 1, antioxidant A 0.8 1.2, antioxidant D 0.8 1.2, calcium carbonate 65, liquid coumarone 10, dibutyl ester 25, carbon black 40, antiscorching agent YG 1 0.2 0.4.Butylbenzene, nitrile rubber and fluid medium solubility parameter great disparity, have preferable oil resistivity；Filler calcium carbonate dosage suitably increases, and contributes to anti-swelling；State of cure (vulcanization) improves, and crosslink density is high, and oil-resistant effect is preferable.With the big primer of formula production, its oil resistance is preferable, and cost is relatively low, adapts to contact the operating environment of oils, and suitable for the protection of oil operations, and process is not susceptible to incipient scorch phenomenon, can greatly improve the security of sizing material processing.
Description
Technical field
The present invention relates to rubber overshoes manufacturing field, is related to the big primer formula of boots, more particularly to a kind of injection pressure for being not easy incipient scorch
The big primer of the resistance to oiled boots of method.
Background technology
Shoes made of General Purpose Rubber material, its big primer are usually that natural rubber adds synthetic rubber, use range is wide,
Cost is low, but because natural rubber and fluid medium solubility parameter are not greatly different enough, causes big primer oil resistivity poor, therefore,
Conventional big primer formula can not be used for the protection boots for contacting oils.
Incipient scorch is a kind of sizing material prevulcanization phenomenon, produce incipient scorch the reason for have：Mismate, such as vulcanizing agent, accelerator
Dosage is too many；Misoperation, as roller temperature is too high, too early add Sulfur or add vulcanizing agent after mixing time it is oversize.It is kneaded uneven
Cause vulcanizing agent and accelerator concentration of local；It is improper that sizing material cooling is parked.Such as park too long, holding area temperature is too high or air
Circulation etc., when there is incipient scorch phenomenon, sizing material is rough, and pitted skin plasticity reduces, and size occurs in sizing material surface when serious
The particle not waited.
Because summer temperature is higher, easily causes resistance to oiled boots and incipient scorch phenomenon occurs when being kneaded and machining with big primer, make
Scrapped into sizing material.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, and to provide a kind of resistance to oiled boots of injection molding for being not easy incipient scorch with big
Primer, with the big primer of formula production, its oil resistance is preferable, and cost is relatively low, adapts to the operating environment of oil resistant, is applied to
The protection of oil resistant operation, and process is not susceptible to incipient scorch phenomenon, can greatly improve the security of sizing material processing.
Realizing the technical scheme of the object of the invention is：
A kind of big primer of resistance to oiled boots of injection molding for being not easy incipient scorch, is calculated in parts by weight, including
Butadiene-styrene rubber 80, nitrile rubber 20, sulphur 2, captax 0.4-0.6, diphenylguanidine 0.1-0.3, altax 0.9-
1.1st, Vulcanization accelerator TMTD 0.1-0.2, zinc oxide 5, stearic acid 1, antioxidant A 0.8-1.2, antioxidant D 0.8-1.2, calcium carbonate
65th, liquid coumarone 10, dibutyl ester 25, carbon black 40, antiscorching agent YG-1 0.2-0.4.
The advantage of the invention is that：Using butylbenzene, nitrile rubber, rubber and fluid medium solubility parameter great disparity, have
Preferable oil resistivity；Softening agent is based on dibutyl ester, and with part coumarone；Filler calcium carbonate dosage suitably increases, and helps
In anti-swelling；State of cure (vulcanization) improves, and crosslink density is high, and oil-resistant effect is preferable.With its oil resistance of the big primer of formula production
Preferably, cost is relatively low, adapts to contact the operating environment of oils, suitable for the protection of oil operations.Gum base ingredients are using anti-scorch
Agent YG-1 prevents the generation of incipient scorch phenomenon, and incipient scorch phenomenon is not susceptible to the resistance to oiled boots that the formula produces with big primer, can be big
Width improves the security of sizing material processing.Avoid the loss of the sizing material incipient scorch caused by temperature rise, roller temperature are too high.
Embodiment
Present invention is further elaborated below by embodiment, but is not limitation of the invention.
A kind of big primer of resistance to oiled boots of injection molding for being not easy incipient scorch, is calculated in parts by weight, including

1.1st, Vulcanization accelerator TMTD 0.1-0.2, zinc oxide 5, stearic acid 1, antioxidant A 0.8-1.2, antioxidant D 0.8-1.2, calcium carbonate
65th, liquid coumarone 10, dibutyl ester 25, carbon black 40, antiscorching agent YG-1 0.2-0.4.
Embodiment：
A kind of big primer of resistance to oiled boots of injection molding for being not easy incipient scorch, is calculated in parts by weight, including
Butadiene-styrene rubber 80, nitrile rubber 20, sulphur 2, captax 0.5, diphenylguanidine 0.2, altax 1.0, accelerator
TMTD 0.15, zinc oxide 5, stearic acid 1, antioxidant A 1.0, antioxidant D 1.0, calcium carbonate 65, liquid coumarone 10, two fourths
Ester 25, carbon black 40, antiscorching agent YG-1 0.3.
Preparation method：
The butadiene-styrene rubber of formula ratio is added in banbury and is kneaded completely, then adds stearic acid, carbon black, accelerator in mill
Middle mixing is complete, and age resistor, plasticizer, filler, the antiscorching agent for adding formula ratio continue to be kneaded completely, are eventually adding sulphur
It is kneaded complete.
