Abstract
A kind of preparation method of the compound modified rubber material of lignin calcium carbonate, belongs to rubber composite preparing technical field, comprises the following steps：Prepare the compound of lignin calcium carbonate, Natural rubber is plasticated, mixing ingredient, obtained elastomeric compound film, elastomeric compound film vulcanizing treatment.Organic modifier of the lignin as calcium carbonate, the compatibility of calcium carbonate and rubber matrix can be improved；And calcium carbonate can prevent the reunion of lignin in mixing process, promote lignin in the base scattered.In a word, lignin and calcium carbonate as filler when show the effect of synergistic reinforcement, and lignin can improve the mechanical property of calcium carbonate in the composite, have modification to calcium carbonate.
Description
Technical field
The invention belongs to rubber composite preparing technical field, and in particular to a kind of compound of lignin calcium carbonate changes
The preparation method of property elastomeric material.
Background technology
Composite is that have different physics and chemical property, in the form of microcosmic or be macroscopical by two or more
Compound and composition heterogeneous material.Because of simple natural rubber or synthetic rubber, whether unvulcanized rubber or vulcanizate, its
Physical and mechanical properties is very poor to be difficult to meet the requirement used.Therefore, Composite is one of inexorable trend of elastomeric material development.
The content of the invention
According to problems of the prior art, the invention provides a kind of compound modified rubber of lignin calcium carbonate
The preparation method of material so that raw material disperses more uniformly in rubber mass, and further increases the mechanics of elastomeric material
Performance.
In order to solve problems of the prior art, the present invention uses following technical scheme：
A kind of preparation method of the compound modified rubber material of lignin calcium carbonate, comprises the following steps：
Step 1：The lignin of 30 parts by weight is mixed with the calcium carbonate of 10 parts by weight, and adds the water of 30 parts by weight, it is high
Speed is stirred 10min, and then mixture is put into ball grinder, with wet ball grinding under 240rpm rotating speed on ball mill
6h, obtain lignin-pearl filler；
Step 2：Natural rubber is plasticated 15-20min on a mill, more than 8h is stood, to eliminate Natural rubber
Internal axial stress；
Step 3：Dispensing is carried out by following parts by weight：100 parts of Natural rubber, 20 parts of lignin-pearl filler,
3 parts of zinc oxide, 2 parts of stearic acid, 1.2 parts of accelerator NS, 1.5 parts of anti-aging agent RD, 1.5 parts of antioxidant 4010NA, 10 parts of white carbon,
1.2 parts of sulphur；Natural rubber is added in mill and is kneaded, other dispensings is added after Natural rubber bag roller, adds
Material order is followed successively by zinc oxide, stearic acid, accelerator, age resistor, white carbon, sulphur, is eventually adding lignin-calcium carbonate and fills out
Material；
Step 4：Triangle bag is beaten, after material dispersion is uniform, adjusts roller square, be orientated then bottom sheet, elastomeric compound is made
Film；
Step 5：Elastomeric compound film is placed into a night, eliminates axial stress, and vulcanized on vulcanizing press, sulphur
Change temperature is 143 DEG C, cure time is 20 minutes.
Preferably, the melting temperature described in step 3 is 30-50 DEG C.
Preferably, roll spacing is adjusted to 0.5mm in step 4, and uses the method for alignment of a bottom sheet, then doubling twice,
The elastomeric compound film that thickness is 2.0mm is made.
Preferably, the time control of the packing triangle described in step 4 is within 10min.
Preferably, described calcium carbonate is 800 mesh heavy acid calcium.
The beneficial effects of the present invention are：
1) compound/rubber composite of lignin-calcium carbonate, has played the strengthening action of lignin, calcium carbonate,
Ensure rubber have it is unique it is elastomeric improve the modulus of rubber simultaneously, it is possessed high-modulus, high rigidity, tear-resistant, resistance to
The a series of excellent properties such as cutting, low-heat-generation, creep resistant, so as to greatly widen the use range of rubber.
2) organic modifier of the lignin as calcium carbonate, the compatibility of calcium carbonate and rubber matrix can be improved；And carbon
Sour calcium can prevent the reunion of lignin in mixing process, promote lignin in the base scattered.In a word, lignin and carbon
The effect of synergistic reinforcement is shown when sour calcium is as filler, and lignin can improve the mechanics of calcium carbonate in the composite
Performance, there is modification to calcium carbonate.
