Description
Technical field
The invention discloses a kind of preparation methods of abrasive rubber, belong to technical field of polymer materials.
Background technology
Rubber industry is one of important foundation industry of national economy.It is indispensable that it not only provides daily life for people
The light industrys rubber product such as daily, medical, and carried to the heavy industry such as digging, traffic, building, machinery, electronics and new industry
For various rubber-producing equipments or rubber components.The wear-resisting property of General Purpose Rubber is weaker, holds after product long-time use obtained
Wear phenomenon easily occurs, its service life is caused to greatly shorten.
Abrasive rubber preparation process traditional at present has degasification technique, cohesion process, liquid nano technique.
It is to select multistage degassing equipment, and combine to contain intermingle with and generally use wet type degasification technique, improvement direction in method production
Solvent removal process is strengthened in the measures such as reducing pressure by regulating flow, to achieve the purpose that energy-saving.In synthetic rubber production technology, nothing
Salt coagulates case technique, and oneself has quickish development.It is completed in the production of butadiene-styrene rubber and uses the salt-free cohesion process of acid.It presses
The mixture of this technique, rubber cement and oil extender is agglomerated in double-screw type agglomerator with sulfuric acid.Compared with traditional cohesion process,
New process can save 250 kgs/tonne of glue of salt, and power content of ashes can reduce by 50% in rubber, and emulsifier content can also subtract significantly
It is few.In addition there are making flocculating agent with lignin machining object, or make the salt-free cohesion work of flocculating agent etc. from matter with polysaccharide, plant egg
Skill, latter of which is it is said that quite promising.Liquid nano formula avoids traditional heating and stirs rubber production technology to rubber height
The destruction of strand.Different from " dry method ", various rubber chemicals can fully be merged with rubber juice in liquid.Fully fusion makes
Various rubber chemicals dosages can be minimum, and rubber content is up to 90% or more.Nanometer increases the wearability of rubber, makes rubber juice
Fusion in liquid is evenly.Room temperature high-frequency vulcanization formula avoids tradition heating stirring rubber production technology to rubber high score
The destruction of subchain reduces the degree of aging of rubber.The inside and outside synchronous solidification of rubber, is unlikely to external cured and internal
" not yet done ".Required temperature is low when the vulcanization of rubber, pressure is low, is destroyed to rubber macromolecule small.Such abrasive rubber another
Distinguishing feature is can to utilize abrasive rubber offset plate arbitrary cold patch on the materials such as steel, stainless steel, cement, plank, solve
The wear-resisting problem of funnel, chute, pipeline, equipment inner wall or roller.But there is also wear-resisting properties for abrasive rubber traditional at present
The problem of can not further increasing, therefore also need to study it.
Invention content
The present invention solves the technical problem of：It is asked for what traditional abrasive rubber wear-resisting property can not further increase
Topic, provides a kind of preparation method of abrasive rubber.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：

The beneficial effects of the invention are as follows：
The present invention is by the modified additive of addition, and first, in preparation process, molecular structure is in modified additive active ingredient
Block copolymer with parents' performance, the block copolymer can be self-assembly of imitated vesicle structure, in high temperature and pressure sulfidation
In, sodium bicarbonate is thermally decomposed to generate carbon dioxide, and the generation of carbon dioxide can be reacted with the amidine group in the block copolymer,
And amidine group is made to become positively charged lotus, since like charges are mutually exclusive so that vesica volume expansion, on the one hand, vesica expansion increases
The elasticity of system is added, on the other hand, the swelling stress of modified vesica makes system be further compacted, and increases system
Consistency, to improve the wear-resisting property of system, meanwhile, in use, swelling stress makes system longitudinal stress
Increase, so that the wear-resisting property of system is further promoted, secondly, expansion vesica carries charge, in friction process
In, due to electrostatic interaction, electrostatic attraction is generated, vesica inflatable elastomeric acts on simultaneously with electrostatic attraction, so that system is resistance to
Mill performance is further promoted.
