Abstract
The invention discloses a kind of big primer of resistance to oiled boots of fitting method that can prevent incipient scorch, calculate in parts by weight, including butadiene-styrene rubber 80, nitrile rubber 20, 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 10 20, pine tar 5, dibutyl ester 15, dark substitute 5, carbon black 40, semi-reinforcing hydrocarbon black 10, antiscorching agent YG 1 0.2 0.4, antiscorching agent PVI 0.1 0.5.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 patch that can prevent incipient scorch
The big primer of legal resistance to oiled boots.
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 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
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 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 big primer of resistance to oiled boots of fitting method that can prevent incipient scorch, is calculated in parts by weight, including
Butadiene-styrene rubber 80, nitrile rubber 20, 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 10-20, pine tar 5, dibutyl ester 15, dark substitute 5, carbon black 40,
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 dosage suitably increases, and contributes to anti-swelling；State of cure (vulcanization) improves, and crosslink density is high, and oil-resistant effect is preferable.Produced with the formula
Big primer its oil resistance it is preferable, cost is relatively low, adapts to contact the operating environment of oils, suitable for the anti-of oil operations
Shield.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 big
Primer is not susceptible to incipient scorch phenomenon, can greatly improve the security of sizing material processing.Antiscorching agent PVI is for being already subjected to high fever simultaneously
Or the sizing material for having slight incipient scorch has reactivation, the process safety of sizing material can be further improved, is avoided because of temperature rise, roller
The too high loss for causing sizing material incipient scorch of temperature.
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 fitting method that can prevent incipient scorch, is calculated in parts by weight, including
Butadiene-styrene rubber 80, nitrile rubber 20, 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 10-20, pine tar 5, dibutyl ester 15, dark substitute 5, carbon black 40,
Semi-reinforcing hydrocarbon black 10, antiscorching agent YG-1 0.2-0.4, antiscorching agent PVI 0.1-0.5.
Embodiment：
A kind of big primer of resistance to oiled boots of fitting method that can prevent incipient scorch, is calculated in parts by weight, including
Butadiene-styrene rubber 80, nitrile rubber 20, neoprene 1.5, sulphur 0.45, captax 0.15, zinc oxide 5, magnesia 4,
Stearic acid 1.5, antioxidant D 2.0, calcium carbonate 15, pine tar 5, dibutyl ester 15, dark substitute 5, carbon black 40, 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.
