Description
Technical field
The present invention relates to retreads precured tread produce and tyre rebuilding field, be specifically related to a kind of for
Permanent tack type rubber cement of presulfurization method tyre rebuilding and preparation method thereof.
Background technology
Presulfurization method tyre rebuilding: precured tread is pasted onto on the carcass polished, then through second time
The cover tire renovation method of sulfuration.Its technical process is through polishing by precured tread, sticks to after being coated with rubber cement
On carcass after polishing, painting rubber cement, upper middle pad glue, it is then charged into envelope, vulcanizes at low-temp low-pressure
Kettle cure becomes the process of retreads.Precured tread: the i.e. adhesive tape that recaps of prevulcanization
Or glue ring.Rubber cement: refer mainly to dissolve by the sizing material appropriate solvent that rubber cement glue formula and compounding process produce add
The liquid/paste that work becomes, for precured tread and the brushing of carcass buffed surface, plays adhesive effect.
In precured tread production process, be polished in the tyre surface back side, then brushing rubber cement, packaging,
Stand-by.The main purpose of brushing rubber cement, one is tyre surface buffed surface to carry out cladding avoid oxidation；Two are to maintain
Good viscosity, can fit tightly with the middle pad glue being attached on carcass buffed surface when tyre rebuilding；Three are
Between rubber cement and the rubber components of other joints, under low temperature, low pressure and special time conditions of vulcanization, make
Can effectively combine between rubber macromolecule, form firm network structure, make each position of retreads become one
Individual firm entirety, it can be seen that, the quality of retreads is played the most crucial effect by rubber cement glue.Due to
Product standby time is different in size, and is affected by transport, weather and condition of storage, the brushing tyre surface back side
Rubber cement occur that viscosity declines, the problem not reaching retreads manufacturing requirements, if being continuing with meeting
Cause not bonding between tread rubber pulp layer and middle pad glue, partial delamination, severe patient occur after retreaded tyre vulcanization
Tire blow-out can be caused.
At present precured tread produce rubber cement used be typically with in pad glue solubilizer and replace, because of in pad glue main
Being the cushioning effect of retreads, its compound physical mechanical performance lays particular emphasis on the coupling of intensity, to reduce wheel
Stress during tire travels is grouped as main purpose, reduces the consumption of reinforcing agent, then can reduce in recipe ingredient
Intensity, and reinforcing agent too much can reduce viscosity, particularly permanent tack is poor, is only suitable for making in a short time
With；Although special adhesive glue formula can overcome the problems referred to above in design, but there is also, rubber and
Tackifying resin content is high, the difficult problems such as viscosity is big, Mooney viscosity is low, causes elastomeric compound roll banding, processing difficulties,
Original way is to use low capacity banbury or mill to carry out mixing, but it is low to there is production efficiency, mixed
The problem of material glue dust dispersion quality difference.
In existing rubber cement glue formula, rubber hydrocarbon content is low, and black-reinforced agent accounting amount is big, sizing material stretching strength
Height, causes the autohension of rubber itself to bring into play；For reducing Mooney viscosity, part formulation also increases
7 parts of aromatic naphtha are added, although add the mobile performance of sizing material, but can separate out in depositing, to viscosity
Long-term keep unfavorable.In existing rubber cement glue formula, tackifying resin selects C5 Petropols and tert-butyl phenol
Formaldehyde resin use, total number is at about 9 parts, and common tackifying resin initial viscosity is preferable, but generally exists
The problem of permanent tack difference, and when large usage quantity, rubber compounding roll banding is serious, and preparation technology is very
Difficulty.
In production technology, in order to make up the problem that viscosity keeps difference, it will usually big at precured tread buffed surface
Amount brushing rubber cement, when do so is easily caused packaging, rubber cement is not done and is adhered on shield, makes shield give a discount,
Easily tear during tyre rebuilding and stick to storeroom, and cause retreads delamination.It addition, current rubber cement glue
In formula, vulcanizing system accelerator be chosen as thiazole accelerator DM and diphenylguanidine diphenylguanidine PG also
With, curingprocess rate is fast, the easy incipient scorch of the course of processing.
In prior art, because precured tread rubber cement viscosity is the most up to standard, the return of goods that are that cause account for about 20%, occur
Tyre surface delamination accounts for about 2%, its exist poor specificity, sensitivity is low, cost is high, productivity is low, qualification rate is low,
Response speed is slow, side effect, weak effect in-convenience in use etc. problems.Therefore, how designing one " should
Permanent tack type rubber cement for presulfurization method tyre rebuilding and preparation method thereof " be the present invention will faced by ask
Topic.
