Abstract
The invention discloses a kind of small primer of resistance to oiled boots of fitting method that can prevent incipient scorch, calculate in parts by weight, including butadiene-styrene rubber 90, nitrile rubber 10, neoprene 1.5, sulphur 0.4 0.5, captax 0.1 0.2, zinc oxide 5, magnesia 4, stearic acid 1.5, antioxidant D 1.5 2.5, calcium carbonate 20 40, pine tar 5, dibutyl ester 15, dark substitute 5, carbon black 20, semi-reinforcing hydrocarbon black 10, antiscorching agent YG 1 0.2 0.4, antiscorching agent PVI 0.1 0.5.With the small 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 small primer formula of footwear, more particularly to a kind of patch that can prevent incipient scorch
The small primer of legal resistance to oiled boots.
Background technology
Handle, refers to the big bottom less than 38 yards, shoes made of General Purpose Rubber material, and its small primer is usually that natural rubber adds
Upper synthetic rubber, use range is wide, cost is low, but because natural rubber and fluid medium solubility parameter are not greatly different enough, causes
Small primer oil resistivity is poor, and therefore, conventional small 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 vamp rubber and incipient scorch phenomenon occurs when being kneaded and machining, 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 the fitting method that can prevent incipient scorch and use
Small primer, with the small primer of formula production, its oil resistance is preferable, and cost is relatively low, adapts to the operating environment of oil resistant, is applicable
In 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 small primer of resistance to oiled boots of fitting method that can prevent incipient scorch, is calculated in parts by weight, including
Butadiene-styrene rubber 90, nitrile rubber 10, neoprene 1.5, sulphur 0.4-0.5, captax 0.1-0.2, zinc oxide 5, oxygen
Change magnesium 4, stearic acid 1.5, antioxidant D 1.5-2.5, calcium carbonate 20-40, pine tar 5, dibutyl ester 15, dark substitute 5, carbon black 20,
Semi-reinforcing hydrocarbon black 10, antiscorching agent YG-1 0.2-0.4, antiscorching agent PVI 0.1-0.5.
The advantage of the invention is that：It is combined using butadiene-styrene rubber and butyronitrile, neoprene, rubber and fluid medium solubility
Parameter great disparity, has preferable oil resistivity；Softening agent is based on dibutyl ester, and with part pine tar, dark substitute；Filler carbonic acid
Calcium, clay dosage suitably increase, and contribute to anti-swelling；State of cure (vulcanization) improves, and crosslink density is high, and oil-resistant effect is preferable.Matched somebody with somebody with this
Small primer its oil resistance just produced is preferable, and cost is relatively low, adapts to contact the operating environment of oils, suitable for oil operations
Protection.Gum base ingredients prevent the generation of incipient scorch phenomenon using antiscorching agent YG-1 and antiscorching agent PVI combinations, are produced with the formula
Small primer be not susceptible to incipient scorch phenomenon, can greatly improve sizing material processing security.Antiscorching agent PVI is for being already subjected to simultaneously
High fever or the sizing material for having slight incipient scorch have reactivation, can further improve the process safety of sizing material, avoid because of temperature liter
High, the too high loss for causing sizing material incipient scorch of roller temperature.
Embodiment
Present invention is further elaborated below by embodiment, but is not limitation of the invention.
A kind of small primer of resistance to oiled boots of fitting method that can prevent incipient scorch, is calculated in parts by weight, including
Butadiene-styrene rubber 90, nitrile rubber 10, neoprene 1.5, sulphur 0.4-0.5, captax 0.1-0.2, zinc oxide 5, oxygen
Change magnesium 4, stearic acid 1.5, antioxidant D 1.5-2.5, calcium carbonate 20-40, pine tar 5, dibutyl ester 15, dark substitute 5, carbon black 20,
Semi-reinforcing hydrocarbon black 10, antiscorching agent YG-1 0.2-0.4, antiscorching agent PVI 0.1-0.5.
Embodiment：
A kind of small primer of resistance to oiled boots of fitting method that can prevent incipient scorch, is calculated in parts by weight, including
Butadiene-styrene rubber 90, nitrile rubber 10, neoprene 1.5, sulphur 0.45, captax 0.15, zinc oxide 5, magnesia 4,
Stearic acid 1.5, antioxidant D 1.9, calcium carbonate 30, pine tar 5, dibutyl ester 15, dark substitute 5, carbon black 20, semi-reinforcing hydrocarbon black 10,
Antiscorching agent YG-1 0.3, antiscorching agent PVI 0.3.
Preparation method：
The rubber of formula ratio is added in banbury and is kneaded completely, stearic acid, carbon black, accelerator is then added and is mixed in mill
Refining is complete, and age resistor, plasticizer, filler, the antiscorching agent for adding formula ratio continue to be kneaded completely, are eventually adding sulphur mixing
Completely.
