Abstract
The invention belongs to the field of composite rubber modification, and particularly relates to a composite rubber material based on natural rubber for a rubber shoe upper and a preparation technology thereof. The composite rubber material is prepared from, by weight, 75 parts of the natural rubber, 22-25 parts of butadiene styrene rubber, 1 part of ethylene-propylene-diene monomer rubber, 2-2.3 parts of sulphur, 0.3-0.35 part of accelerators M, 0.2-0.25 part of accelerators D, 1.1-1.3 parts of accelerators DM, 5 parts of zinc oxide, 0.5-0.7 part of stearic acid, 2-2.5 parts of polyethylene glycol, 20-25 parts of white carbon black, 1.5 parts of anti-aging agents, 90-100 parts of light calcium carbonate and 1.5-2 parts of RX-80 resin. By adding a little amount of the ethylene-propylene-diene monomer rubber in the formula, the heat resistance, the ozone resistance and the weather resistance of vulcanized rubber are effectively improved.
Description
Technical field
The invention belongs to the modified field of compounded rubber, more particularly to a kind of rubber overshoes vamp compound adhesive based on natural rubber
Material and its preparation technology.
Background technology
Natural rubber has very high elasticity, at a relatively high tensile strength and tearing strength, and cohesive is good, also with good
Comprehensive process performance, be the best general purpose rubber of combination property.Because containing active higher double bond in its molecular chain structure,
Easily react with the ozone etc. in air, so its heat oxygen aging resistance, ozone resistance are all poor, product service life is short,
These characteristics limit its application in some special occasions.
The content of the invention
The technical problem to be solved is：Natural rubber heat oxygen aging resistance, ozone resistance are poor, service life
It is short.
To solve above-mentioned technical problem, the invention provides a kind of rubber overshoes vamp modified compound rubber, according to weight portion
Number calculate by
Composition.
Present invention also offers a kind of preparation method of above-mentioned rubber overshoes vamp modified compound rubber：
To plasticate in the sizing material input banbury of (flexibility is 0.4, parks and is kept for 12 hours) up to standard, add each filler,
90 DEG C knead 7 to 8 minutes, and elastomeric compound carries out filter glue after parking 8 hours, and 85 DEG C of mills and sulfur is added after filter glue, treat sulfur and
After sizing material mixing completely, then beat triangle bag 5 to 8 times, plus the good sizing material of sulfur turn refining into 60～70 DEG C of rubber mixing machine it is uniform, after clot
Into five-roller calendering formation, roller temperature is from bottom to top respectively 75 DEG C, 80 DEG C, 85 DEG C, 90 DEG C, 95 DEG C, obtains modified compound rubber
Glue,
Wherein, filter glue temperature is maintained at 85 to 95 DEG C.
The beneficial effects of the present invention is：By adding minimal amount of ethylene propylene diene rubber in formula, effectively improve
Heat-resisting, the resistance to ozone of vulcanizate, against weather, the characteristic of easily reverting (aging, cracking) that effectively compensate for natural gum, it is resistance to old
Change performance to be obviously improved；And because the addition of ethylene propylene diene rubber is few, the mechanical performance of natural rubber will not be caused
Decline, taken into account the mechanical property and service life of Composite rubber material.
Specific embodiment
Embodiment 1
A kind of rubber overshoes vamp modified compound rubber, in parts by weight by
Composition,
The preparation method of above-mentioned rubber overshoes vamp modified compound rubber is：
To plasticate in the sizing material input banbury of (flexibility is 0.4, parks and is kept for 12 hours) up to standard, add each filler
(remove sulfur), 90 DEG C knead 7 to 8 minutes, and elastomeric compound carries out 85 DEG C of filter glues after parking 8 hours, 85 DEG C of mills and add after filter glue
Sulfur, after sulfur and sizing material mixing completely, then beats triangle bag 5 to 8 times, plus the good sizing material of sulfur turns refining for 65 DEG C into rubber mixing machine
It is even, five-roller calendering formation is entered after clot, roller temperature is from bottom to top respectively 75 DEG C, 80 DEG C, 85 DEG C, 90 DEG C, 95 DEG C, is changed
Property compounded rubber.
Comparative example 1
Compared to embodiment 1, the consumption of ethylene propylene diene rubber is increased in this comparative example；Meanwhile, in order to improve increase that
The processing characteristics of part ethylene propylene diene rubber, remaining auxiliary agent is also required to accordingly increased, specific as follows：
A kind of rubber overshoes vamp modified compound rubber, in parts by weight by
Composition,
The preparation method of above-mentioned rubber overshoes vamp modified compound rubber such as embodiment 1.
Comparative example 2
Compared to comparative example 1, the consumption of ethylene propylene diene rubber is further increased in this comparative example；Meanwhile, in order to improve increasing
Plus part ethylene propylene diene rubber processing characteristics, remaining auxiliary agent is also required to accordingly increased, specific as follows：
A kind of rubber overshoes vamp modified compound rubber, in parts by weight by
Composition,
The preparation method of above-mentioned rubber overshoes vamp modified compound rubber such as embodiment 1.
Comparative example 3
(compared to embodiment 1, any ethylene propylene diene rubber being not added with this comparative example)
A kind of rubber overshoes vamp modified compound rubber, in parts by weight by
Composition,
The preparation method of above-mentioned rubber overshoes vamp modified compound rubber such as embodiment 1.
To the shore hardness of elastomeric material product in the various embodiments described above, comparative example, tensile strength, elongation at break and resistance to
The ozone-induced cracking time is tested, and test condition is：Ozone concentration is 50pphm, and humidity is 50%, test piece pre-stretching 25%, temperature
Spend for 40 DEG C.Test result such as table 1：
Table 1
Can be seen that from the comparative example 1,2 of table 1：When ethylene propylene diene rubber is used as base rubber, with consumption
Increase its ozone-resistant aging property can have a certain upgrade, but mechanical property also can be affected；And by three in the present invention
First EP rubbers is used as filler, and consumption is few, and the mechanical performance of natural rubber will not be caused to decline, and has taken into account compound adhesive
The mechanical property and service life of material.
