Abstract
The invention discloses a kind of big primer of acidproof boots for being not easy incipient scorch, it is characterised in that calculate in parts by weight, including：Natural rubber 100, zinc oxide 46, stearic acid 1.5 2.5, carbon black 40, captax 1.0 1.4, diphenylguanidine 0.3 0.4, altax 0.8 1.0, antioxidant D 0.8 1.2, sulphur 2.2 2.4, industrial fat 8 10, liquid coumarone 12 14, solid coumarone 24, barium sulfate 72, 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 big primer, 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 the big primer formula of footwear, more particularly to a kind of incipient scorch that is not easy
The big primer of acidproof boots.
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 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 acidproof boots for being not easy incipient scorch big primer,
With the big primer of the acidproof boots for being not easy incipient scorch that the formula produces, its acid resistance is preferable, and cost is relatively low, adapts to sour environment
Application, the service life of boots can be greatly improved.
Realizing the technical scheme of the object of the invention is：
A kind of big primer of acidproof boots for being not easy incipient scorch, is calculated in parts by weight, including：
Natural rubber 100, zinc oxide 4-6, stearic acid 1.5-2.5, carbon black 40, captax 1.0-1.4, diphenylguanidine 0.3-
0.4th, altax 0.8-1.0, antioxidant D 0.8-1.2, sulphur 2.2-2.4, industrial fat 8-10, liquid coumarone 12-14,
Solid coumarone 2-4, barium sulfate 72, 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 big primer, 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 big primer of acidproof boots for being not easy incipient scorch, is calculated in parts by weight, including：
Natural rubber 100, zinc oxide 4-6, stearic acid 1.5-2.5, carbon black 40, captax 1.0-1.4, diphenylguanidine 0.3-
0.4th, altax 0.8-1.0, antioxidant D 0.8-1.2, sulphur 2.2-2.4, industrial fat 8-10, liquid coumarone 12-14,
Solid coumarone 2-4, barium sulfate 72, 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.
Embodiment：
A kind of big primer of acidproof boots for being not easy incipient scorch, is calculated in parts by weight, including：
3L standard rubbers 100, zinc oxide 5, stearic acid 2, carbon black 40, captax 1.2, diphenylguanidine 0.35, altax
0.9th, antioxidant D 1.0, sulphur 2.3, industrial fat 9, liquid coumarone 13, solid coumarone 3, barium sulfate 72, 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 are kneaded completely in mill, add the age resistor of formula ratio and plasticizer continues to be kneaded completely, be eventually adding
Sulphur is kneaded complete.
