Description
Technical field
The present invention relates to gum filler fields, and in particular to a kind of preparation method of rubber modification infusorial earth filler.
Background technique
With the development of rubber industry, requirement of the people for rubber product is higher and higher, but not only price is high for pure rubber
It is expensive, and self-strength is low, heat-resisting and poor corrosion resistance, therefore usually requires that filler is added to it, is enhancing its mechanical property
While substantially reduce the production cost of sizing material.Therefore, a kind of suitable filler is selected to enhance rubber be always people's research
Hot spot.Current gum filler mainly has carbon black and white carbon black, silicates inorganic filler, carbonate inorganic filler etc..
However carbon black will cause serious air pollution during rubber processing, white carbon black in its production process there is also waste water,
The pollution problems such as waste residue, and someone uses diatomite as silicon source to refine SiO currently on the market2To produce white carbon black.Diatom
Soil is the Diatomeae remains grown in ocean or lake, the siliceous sedimentary rock gradually formed through natural environment effect, mineral
Ingredient is amorphous state opal.Diatomite because have unique shell structure, strong adsorptivity, bigger serface, high porosity and
The advantageous properties such as high temperature resistant and be widely used in the fields such as chemical industry, petroleum, building materials and food.Diatomite has light and porosity
The characteristics of, it can be used as filler alternative carbon black through organic modification of surface, significantly improve the tensile strength of rubber product, hardness and resistance to
Mill property etc..Therefore, diatomite is the mineral material that rubber industry has wide application prospect.Due to diatomite contain it is a certain amount of
Organic matter, and the content of organic matter is different with the difference in the place of production.When usually as polymer carrier, need to diatomite into
Row calcining, removes organic matter therein, then through coupling agent surface treatment to improve its compatibility with high molecular material.But it is coupled
Agent price is higher, and surface modification technology is complicated, directly affects the industrial applications of tripolite filling material.
Summary of the invention
Technical problems to be solved: the object of the present invention is to provide a kind of preparation sides of rubber modification infusorial earth filler
The mechanical property of method, obtained reinforced rubber is good.
A kind of technical solution: preparation method of rubber modification infusorial earth filler, comprising the following steps:
S1. diatomite is crushed, deionized water dispersion is added, is stirred after infiltration, is stood after stirring and extracts upper layer suspension, then
By bottom precipitation cleaning, drying repeatedly, the diatomite purified；
S2. diatomite and glucose are mixed, deionized water is uniformly added afterwards and stirs evenly for ground and mixed；
S3. the step S2 mixed solution prepared is placed in hydrothermal reaction kettle, room temperature is cooled to after heating, obtains glucose-
Diatomite nano composite material；
S4. glucose-diatomite nano composite material that step S3 is prepared is calcined under oxygen-free environment, is subsequently cooled to
Room temperature obtains the modified diatomite composite material of charing；
S5. the modified diatomite composite material of the charing that above-mentioned steps are prepared is cleaned with hydrochloric acid and deionized water repeatedly,
Then configuration concentration is the diatomite suspension of 100-250g/L；
S6. by starch dissolution after heating stirring is uniform in deionized water, the pH most 11 of lye to starch solution is added dropwise, then
Adipic acid solution is added, heating is uniformly mixed, and the content of fatty acid is the 1/10-1/5 of starch total amount；
S7. the diatomite suspension in step S5 is added in the mixed solution in step S6, after mixing evenly, acid solution tune is added
Section pH is 3-4, is then centrifuged for obtaining modification infusorial earth filler, washing to neutrality.
Further, the mass ratio of diatomite and glucose is 1:0.5-1 in the step S2.
Further, in the step S3 hydro-thermal reaction condition: react 2h at 150 DEG C, be warming up at 170 DEG C and react 2h,
It is warming up at 200 DEG C and reacts 4h, be warming up at 220 DEG C and react 2h.
Further, the temperature calcined in the step S4 is 700-900 DEG C, time 0.5-1h.
Further, the concentration of starch solution is 20-25%, starch solution and adipic acid solution heating temperature in the step S6
It is 100 DEG C, incorporation time 30-50min.
Further, the mass ratio of starch and diatomite is 1:3-6 in the step S7.
The utility model has the advantages that the invention has the following advantages that the resilience for dosing modified starch rubbery sample improves, this is primarily due to
Starch molecule itself is a kind of macromolecule, and flexibility is relatively good, and when rubber is by external force, rubber macromolecule and starch are high
Molecule can be obedient to external force direction, and strand being capable of spread apart.However, warm-up movement attempts to make strand disordering again, so as to
It is set to be returned to rolled state, so strand can be promptly restored to original state when external force removes；It is calcined by anoxic
The diatomite of processing has coated one layer of amorphous carbon on diatom test surface, and the presence of amorphous carbon has the work of similar carbon black
With, that is, improve rubber molecular chain bridging property, be conducive to increase diatomite and rubber compatibility；Meanwhile porous diatomite
The rubber molecular chain in insertion duct can be captured, the strand of polymer is made to be firmly adsorbed on diatomite surface, improves rubber
The mechanical property of glue.
