Description

A kind of injection molding oil resistant anti-static shoes vamp rubber that can prevent incipient scorch

Technical field

The present invention relates to rubber overshoes manufacturing fields, are related to shoes vamp glue formula more particularly to a kind of note that can prevent incipient scorch Platen press oil resistant anti-static shoes vamp rubber.

Background technique

Shoes made of General Purpose Rubber material, vamp rubber are usually natural rubber plus synthetic rubber, use scope is wide, It is at low cost, but since natural rubber and oil liquid medium solubility parameter are not greatly different enough, cause vamp rubber oil resistivity poor, therefore, Common vamp glue formula can not be used to contact the protection boots of oils；Shoes made of General Purpose Rubber material, do not have The effect of antistatic was easy to produce in the season of electrostatic, and people's electrostatic arc that moment generates when touching metal object can make one It frightens, generates shouting pain, very uncomfortable feeling, and thus generate pavid psychology, metal object dare not be contacted；Electrostatic arc is some In the biggish workshop of dust, or even explosion accident can occur, therefore the influence for eliminating electrostatic has weight to people's lives, production Big meaning.

The reason of incipient scorch is a kind of sizing material prevulcanization phenomenon, generates incipient scorch has: mismate, such as vulcanizing agent, promotor Dosage is too many；Misoperation, as roller temperature is excessively high, too early be added Sulfur or be added vulcanizing agent after mixing time it is too long.It is kneaded uneven Cause vulcanizing agent and promotor concentration of local；It is improper that sizing material cooling is parked.It such as parks too long, holding area temperature is excessively high or air Circulation etc., when there is incipient scorch phenomenon, sizing material is rough, and pitted skin plasticity reduces, and sizing material surface will appear size when serious Not equal particle.

Since summer temperature is higher, it be easy to cause oil-resistant shoe vamp rubber that incipient scorch phenomenon occurs when being kneaded machining, makes It is scrapped at sizing material.

Summary of the invention

The purpose of the present invention is in view of the deficiencies of the prior art, and provide a kind of injection molding oil resistant that can prevent incipient scorch prevent it is quiet Electric shoes vamp rubber, with the vamp rubber of formula production, its oil resistance is preferable, and cost is relatively low, adapts to the operation ring of oil resistant Border, suitable for the protection of oil resistant operation, and electric conductivity is excellent, plays excellent anti-static effect, and process is not susceptible to Incipient scorch phenomenon can greatly improve the safety of sizing material processing.

Realizing the technical solution of the object of the invention is:

A kind of injection molding oil resistant anti-static shoes vamp rubber that can prevent incipient scorch, in parts by weight, including

Butadiene-styrene rubber 100, captax 0.4-0.6, diphenylguanidine 0.1-0.3, altax 0.9-1.1, promotees sulphur 2 Into agent TMTD 0.1-0.2, zinc oxide 5, stearic acid 1, antioxidant A 0.8-1.2, antioxidant D 0.8-1.2, calcium carbonate 100, liquid coumarone 10, dibutyl ester 25, carbon black 5, high electric conductivity carbon black 8-12, antiscorching agent YG-1 0.2-0.4, antiscorching agent PVI 0.1-0.5。

The present invention has the advantages that using butadiene-styrene rubber, raw rubber and oil liquid medium solubility parameter great disparity have preferable Oil resistivity；Softening agent is based on dibutyl ester, and with part coumarone；Filler calcium carbonate dosage suitably increases, and helps to resist molten It is swollen；State of cure (vulcanization) improves, and crosslink density is high, and oil-resistant effect is preferable.With the vamp rubber of formula production, its oil resistance is preferable, at This is lower, adapts to the operating environment of contact oils, the protection suitable for oil operations.And the addition of high electric conductivity carbon black makes vamp Glue electric conductivity is excellent, and the electrostatic that human body generates in the process of wearing is discharged by vamp rubber, to play excellent anti- Electrostatic efficiency.Gum base ingredients prevent the generation of incipient scorch phenomenon using antiscorching agent YG-1 and antiscorching agent PVI combination, raw with the formula The vamp rubber of production is not susceptible to incipient scorch phenomenon, can greatly improve the safety of sizing material processing.Antiscorching agent PVI is for having passed through simultaneously By high fever or there is the sizing material of slight incipient scorch that there is reactivation, can be further improved the process safety of sizing material, avoid because of temperature It increases, the excessively high loss for causing sizing material incipient scorch of roller temperature.
