Abstract
The invention discloses a kind of acidproof footwear vamp rubber that can prevent incipient scorch, it is characterised in that calculate in parts by weight, including：Natural rubber 80 90, butadiene-styrene rubber 10 20, zinc oxide 46, stearic acid 0.3 0.8, furnace black 34, captax 0.5 0.7, altax 0.4 0.6, diphenylguanidine 0.2 0.4, antioxidant D 13, sulphur 2.1 2.3, industrial fat 0.1 0.3, paraffin 0.2 0.4, liquid coumarone 1.4 1.6, clay 70, salicylic acid 0.2 0.4, anti-scorching agent CTP 0.1 0.5.The advantage of the invention is that：Gum base ingredients prevent the generation of incipient scorch phenomenon using salicylic acid and anti-scorching agent CTP combination, and the vamp rubber produced with the formula is not susceptible to incipient scorch phenomenon, can greatly improve the security of sizing material processing.Anti-scorching agent CTP has reactivation for the sizing material for being already subjected to high fever or having slight incipient scorch simultaneously, can further improve the process safety of sizing material, avoids the loss of the sizing material incipient scorch caused by temperature rise, roller temperature are too high.
Description
Technical field
The present invention relates to elastomeric material preparation field, is related to footwear vamp rubber formula, more particularly to one kind can prevent incipient scorch
Acidproof footwear vamp rubber.
Background technology
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 acidproof footwear 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 acidproof footwear vamp that can prevent incipient scorch
Glue, the acidproof footwear vamp rubber that can prevent incipient scorch produced with the formula, its acid resistance is preferable, and cost is relatively low, adapts to acid
The application of property environment, the service life of shoes can be greatly improved.
Realizing the technical scheme of the object of the invention is：
A kind of acidproof footwear vamp rubber that can prevent incipient scorch, is calculated in parts by weight, including：
Natural rubber 80-90, butadiene-styrene rubber 10-20, zinc oxide 4-6, stearic acid 0.3-0.8, furnace black 3-4, captax
0.5-0.7, altax 0.4-0.6, diphenylguanidine 0.2-0.4, antioxidant D 1-3, sulphur 2.1-2.3, industrial fat 0.1-
0.3rd, paraffin 0.2-0.4, liquid coumarone 1.4-1.6, clay 70, salicylic acid 0.2-0.4, anti-scorching agent CTP 0.1-0.5.
The advantage of the invention is that：Gum base ingredients prevent the production of incipient scorch phenomenon using salicylic acid and anti-scorching agent CTP combination
Raw, the vamp rubber produced with the formula is not susceptible to incipient scorch phenomenon, can greatly improve the security of sizing material processing.Antiscorching agent simultaneously
CTP has reactivation for the sizing material for being already subjected to high fever or having slight incipient scorch, can further improve the process safety of sizing material
Property, 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 acidproof footwear vamp rubber that can prevent incipient scorch, is calculated in parts by weight, including：
Natural rubber 80-90, butadiene-styrene rubber 10-20, zinc oxide 4-6, stearic acid 0.3-0.8, furnace black 3-4, captax
0.5-0.7, altax 0.4-0.6, diphenylguanidine 0.2-0.4, antioxidant D 1-3, sulphur 2.1-2.3, industrial fat 0.1-
0.3rd, paraffin 0.2-0.4, liquid coumarone 1.4-1.6, clay 70, salicylic acid 0.2-0.4, anti-scorching agent CTP 0.1-0.5.
The formula can carry out two sections by banbury and be kneaded completion, to improve the cohesive of sizing material.
Natural rubber is 3L standard rubbers, and standard rubbers, butadiene-styrene rubber add up to content to be 100 parts by weight.
Embodiment：
A kind of acidproof footwear vamp rubber that can prevent incipient scorch, is calculated in parts by weight, including：
3L standard rubbers 90, butadiene-styrene rubber 10, zinc oxide 5, stearic acid 0.5, furnace black 3.5, captax 0.6, altax
0.5th, diphenylguanidine 0.3, antioxidant D 2, sulphur 2.2, industrial fat 0.2, paraffin 0.3, liquid coumarone 1.5, clay 70,
Salicylic acid 0.3, anti-scorching agent CTP 0.3.
Preparation method：
The natural rubber of formula ratio, butadiene-styrene rubber are added in banbury and are kneaded completely, then adds zinc oxide, stearic acid, oven process
Carbon black, accelerator be kneaded in mill completely, add formula ratio salicylic acid, age resistor and plasticizer continue to be kneaded it is complete,
Sulphur is eventually adding to be kneaded completely.
