Abstract
The invention discloses a kind of acidproof boots vamp rubber for being not easy 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, calcium carbonate 32, barium sulfate 70, salicylic acid 0.2 0.4.Gum base ingredients prevent the generation of incipient scorch phenomenon using salicylic acid, and the acidproof boots produced with the formula are not susceptible to incipient scorch phenomenon with vamp rubber, can greatly improve the security of sizing material processing.Avoid 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, be related to footwear vamp rubber formula, more particularly to a kind of incipient scorch that is not easy
Acidproof boots 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 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 acidproof boots vamp rubber for being not easy incipient scorch,
The acidproof vamp rubber produced with the formula 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 acidproof boots vamp rubber for being not easy 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, calcium carbonate 32, barium sulfate 70, salicylic acid 0.2-0.4.
The advantage of the invention is that：Gum base ingredients prevent the generation of incipient scorch phenomenon using salicylic acid, are produced with the formula
Acidproof boots be not susceptible to incipient scorch phenomenon with vamp rubber, can greatly improve sizing material processing security.Avoid 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 acidproof boots vamp rubber for being not easy 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, calcium carbonate 32, barium sulfate 70, salicylic acid 0.2-0.4.
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 boots vamp rubber for being not easy 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, calcium carbonate
32nd, barium sulfate 70, salicylic acid 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.
