Abstract
The invention belongs to compounded rubber modification field, particularly a kind of rubber overshoes vamp Composite rubber material based on natural rubber and preparation technology thereof.Composite rubber material calculates according to parts by weight and is made up of natural rubber 75 parts, 22 ~ 25 parts, styrene-butadiene rubber(SBR), terpolymer EP rubber 1 part, 2 ~ 2.3 parts, sulphur, captax 0.3 ~ 0.35 part, vulkacit D 0.2 ~ 0.25 part, altax 1.1 ~ 1.3 parts, 5 parts, zinc oxide, stearic acid 0.5 ~ 0.7 part, polyoxyethylene glycol 2 ~ 2.5 parts, white carbon black 20 ~ 25 parts, 1.5 parts, anti-aging agent, light calcium carbonate 90 ~ 100 parts, RX-80 resin 1.5 ~ 2 parts.By adding the terpolymer EP rubber of seldom amount in formula, effectively improve heat-resisting, resistance to ozone, the weathering resistance of cross-linked rubber.
Description
Technical field
The invention belongs to compounded rubber modification field, particularly a kind of rubber overshoes vamp Composite rubber material based on natural rubber and preparation technology thereof.
Background technology
Natural rubber has very high elasticity, quite high tensile strength and tear strength, and binding property is good, also has good comprehensive process performance, is the best general purpose rubber of over-all properties.Because of in its molecular chain structure containing active higher double bond, the ozone etc. easily and in air reacts, so its heat oxygen aging resistance, ozone resistance are all poor, product is short for work-ing life, and these characteristics limit its application at some special occasions.
Summary of the invention
Technical problem to be solved by this invention is: natural rubber heat oxygen aging resistance, ozone resistance are poor, and work-ing life is short.
For solving the problems of the technologies described above, the invention provides a kind of rubber overshoes vamp modified compound rubber, according to parts by weight calculate by
Composition.
Present invention also offers a kind of preparation method of above-mentioned rubber overshoes vamp modified compound rubber:
To plasticate, up to standard (plasticity number is 0.4, park maintenance 12 hours) sizing material drop in Banbury mixer, add each filler, 90 DEG C mixing 7 to 8 minutes, rubber unvulcanizate is parked after 8 hours and is carried out filter glue, open and refine and add sulphur for 85 DEG C after filter glue, after sulphur and sizing material mixing completely, play triangle bag again 5 to 8 times, add the good sizing material of sulphur to enter rubber mixing machine 60 ~ 70 DEG C and turn refining evenly, enter five-roller calendering formation 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, obtain modified compound rubber
Wherein, filter glue temperature and remain on 85 to 95 DEG C.
Beneficial effect of the present invention is: by adding the terpolymer EP rubber of seldom amount in formula, effectively improve heat-resisting, the resistance to ozone of cross-linked rubber, weathering resistance, effectively compensate for the characteristic of easily reverting (aging, be full of cracks) of natural gum, ageing-resistant performance improves obviously; And because the add-on of terpolymer EP rubber is few, decline can not be caused to the mechanical property of natural rubber, take into account mechanical property and the work-ing life of Composite rubber material.
Embodiment
Embodiment 1
A kind of rubber overshoes vamp modified compound rubber, according to parts by weight calculate by
Composition,
The preparation method of above-mentioned rubber overshoes vamp modified compound rubber is:
To plasticate, up to standard (plasticity number is 0.4, park maintenance 12 hours) sizing material drop in Banbury mixer, add each filler (except sulphur), 90 DEG C mixing 7 to 8 minutes, rubber unvulcanizate is parked after 8 hours and is carried out 85 DEG C of filter glue, open and refine and add sulphur for 85 DEG C after filter glue, after sulphur and sizing material mixing completely, play triangle bag again 5 to 8 times, add the good sizing material of sulphur to enter rubber mixing machine 65 DEG C and turn refining evenly, enter five-roller calendering formation 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, obtains modified compound rubber.
Comparative example 1
Compared to embodiment 1, in this comparative example, increase the consumption of terpolymer EP rubber; Meanwhile, in order to improve the processing characteristics of the part terpolymer EP rubber of increase, all the other auxiliary agents also need correspondingly to increase to some extent, specific as follows:
A kind of rubber overshoes vamp modified compound rubber, according to parts by weight calculate by
Composition,
The preparation method of above-mentioned rubber overshoes vamp modified compound rubber is as embodiment 1.
Comparative example 2
Compared to comparative example 1, in this comparative example, increase the consumption of terpolymer EP rubber further; Meanwhile, in order to improve the processing characteristics of the part terpolymer EP rubber of increase, all the other auxiliary agents also need correspondingly to increase to some extent, specific as follows:

Composition,
The preparation method of above-mentioned rubber overshoes vamp modified compound rubber is as embodiment 1.
Comparative example 3
(compared to embodiment 1, in this comparative example, not adding any terpolymer EP rubber)
A kind of rubber overshoes vamp modified compound rubber, according to parts by weight calculate by
Composition,
The preparation method of above-mentioned rubber overshoes vamp modified compound rubber is as embodiment 1.
The shore hardness of elastomeric material product in the various embodiments described above, comparative example, tensile strength, tensile yield and resistance to ozone-induced cracking time are tested, test condition is: ozone concn is 50pphm, humidity is 50%, test piece preliminary draft 25%, and temperature is 40 DEG C.Test result is as table 1:
Table 1
As can be seen from the comparative example 1,2 of table 1: when terpolymer EP rubber uses as base rubber, along with its ozone-resistant aging property of increase of consumption can have a certain upgrade, but mechanical property also can be affected; And in the present invention, terpolymer EP rubber is used as filler, consumption is few, can not cause decline, taken into account mechanical property and the work-ing life of Composite rubber material to the mechanical property of natural rubber.
