Description
Technical field
The present invention relates to a kind of method that composite modified cerium oxide improves kiss-coating grip-pad rubber performance, belong to advanced composite material and prepare and modified rubber technical matters field.
Background technology
Rubber as strategic goods and materials in national economy in occupation of critical role, the visco-elasticity of its uniqueness and consistency are that other material is incomparable, and its utility value is increasingly extensive along with the development of economy and society.
Rubber obtains significant development along with world's new and high technology, effectively facilitate the development of rubber industry, the application of new and high technology is all benefited from the progress of its novel starting material, product innovation, new installation and novel process etc., and utilizing new and high technology to transform traditional rubber industry has become inevitable.
Rare earth/macromolecular material can be divided into two large types from the application of rare earth: one is that rare earth compound is distributed to monomer or polymkeric substance equably as doping agent, makes the doping type rare earth high polymer existed with doping way; Two is that rare earth compound participates in polymerization or condensation with monomeric form, or rare earth compound coordination is on polymer lateral chain, obtains the bonding type rare earth high polymer existed with bonding pattern.Rare earth new material can be used as the just face treatment agent of the synthetic catalyst of rubber, vulcanization accelerator, anti-aging agent, strengthening agent and loading material of rubber.
Because the physicals of many rubber ingredients differs comparatively large with rubber matrix, particularly some mineral fillers, make it in the adding procedure of rubber, be subject to a definite limitation.Therefore much research shows carrying out modified to rubber ingredients, better can improve the performance of rubber each side, such as silicon-dioxide, calcium carbonate, barite etc.
Chinese patent CN101456974A reports a kind of method of rare-earth additive modified rubber, but it relate to the wear resistance of rubber, and other mechanical property not mentioned.
And present invention employs the composite rubber ingredients of multiple modified oxidized cerium, change order of addition(of ingredients), to obtain high performance kiss-coating grip-pad rubber.
Summary of the invention
The technical issues that need to address of the present invention are just the defect overcoming prior art, a kind of composite modified cerium oxide is provided to improve the method for kiss-coating grip-pad rubber performance, the present invention adds the cerium oxide after organic surface treatment, improve the consistency of mineral filler and rubber matrix, the cerium oxide of different modifier treatment to improve the type of performance of rubber also different.
For solving the problem, the present invention adopts following technical scheme:
The invention provides a kind of method that composite modified cerium oxide improves kiss-coating grip-pad rubber performance, with two or more properties-correcting agent, respectively modification is carried out to cerium oxide, keeping on the basis that the original production formula of rubber is constant and Production Flow Chart is constant, the composite modified cerium oxide of 0.1 ~ 10% is added by the method for mechanical blending, improve the performance of kiss-coating grip-pad rubber, particularly wear resisting property and tear resistance.
Specifically comprise the following steps:
(1), in advance cerium oxide is added water infiltration and break up process, solid-to-liquid ratio is (8-200): 1g/mL;
(2), with coupling agent or anion surfactant for properties-correcting agent, adopt two or more properties-correcting agent to carry out surface modification to cerium oxide respectively, react for liquid phase method;
Water-soluble for the properties-correcting agent of cerium oxide weight 1% ~ 8% or ethanol are made into 600mL clear solution, with peristaltic pump, this solution are added drop-wise to constant temperature stirring reaction in cerium oxide, peristaltic pump feed time is 0.5 ~ 3h; Temperature of reaction is 20 ~ 90 DEG C, and the reaction times is 0.5 ~ 6h, and stirring velocity is 500 ~ 1500r/min; Leave standstill and get upper solution, suction filtration, dry, obtain modified oxidized cerium;
(3) composite modified cerium oxide is added in mixing.
In the present invention, properties-correcting agent is at least two kinds in lauric acid, stearic acid, sodium lauryl sulphate, Sodium dodecylbenzene sulfonate, sodium laurylsulfonate or silane coupling agent.
In the present invention, composite modified cerium oxide added in the stage of plasticating; Or jointly add in Banbury mixer with the small powder such as stearic acid, zinc oxide; Or jointly add with sulphur on a mill until.
Particularly, rubber is put into Banbury mixer to plasticate through 3 ~ 5 minutes, add small powder and composite modified cerium oxide, carbon black divides 2 times and adds, banburying 15 ~ 30 minutes, adds Sulfur after taking-up on a mill until, mixing evenly rear bottom sheet, park 24 hours, at 151 DEG C, press sulfurizing time sulfuration with vulcanizing press.
Advantage of the present invention is: by changing the order of addition(of ingredients) adding modified oxidized cerium, can improve the dispersiveness of rare-earth additive, improves the consistency with rubber, better improves the effect playing rare-earth additive, improves the mechanical property of rubber track plate further.Adopt the method for mechanical blending to add modified oxidized cerium particle, method is simple, and simple operation, is applicable to suitability for industrialized production.
Rubber track plate prepared by the inventive method, add owing to have employed the composite of two kinds of modified oxidized ceriums, can reach the object improving rubber wear-resisting performance and tear resistance, what avoid single rare earth auxiliary agent adds the shortcoming that can not obtain excellent over-all properties simultaneously.
The rubber tensile intensity that the present invention obtains and tear strength improve 11% and 41% respectively, and wear loss reduces 16%, are applicable to the big machinery rubber belt tracks such as tank, boom crane, agricultural harvester.
