Description
Technical field
The invention belongs to rubber composite field, and in particular to one kind is based on discarded bamboo pulp fiber paper and hydrogenated butyronitrile rubber
The preparation method of glue composite.
Background technology
For nitrile rubber due to the presence of carbon-carbon double bond, it has poor cold resistance and the ozone aging resistance of the diaphragm, chemical proofing, hydrogenation
Nitrile rubber has the performance more excellent than nitrile rubber for nitrile rubber.Hydrogenation modification is the weight of modified rubber
One of direction is wanted, hydrogenation modification improves the oxytolerant of polymer, heat-resisting, ageing-resistant performance, extends the life-span of polymer, expands
The application field of tartan.Unsaturated rubber typically all can be hydrogenated modification.Rubber hydrogenation is mainly hydrogen and rubber
Unsaturated double-bond on xanthan molecule chain plays addition reaction, and C=C double bonds in macromolecular are the interior double of symmetrical diene alkyl substitution mostly
Key, to addition reaction and torpescence, it is often necessary to carry out catalytic hydrogenation from special catalyst, significant hydrogenation could be obtained
Speed.
Cellulose has the advantages that wide material sources, cost are cheap, renewable, degradable, environment-friendly and low-density.In paper
Containing more string, the consumption of paper is very big, but the recycling to waste paper is not highly desirable, therefore can be with
Nano-cellulose can be made by it after hydrolysis by containing more cellulose using waste paper, and it has larger specific surface area and more
Perfect crystalline texture, mechanical property are more excellent.As the new supporting material of rubber, can be brought for rubber industry
Huge economic benefit and social benefit.
Su Lin exist《The preparation of hydrogenated nitrile-butadiene rubber and modification application》After hydrogenation modification being carried out with hydrazine hydrate method to NBR latex,
Powder hydrogenated nitrile-butadiene rubber is prepared using coacervation, the powder hydrogenated nitrile-butadiene rubber prepared is wear-resisting, low temperature resistant（-40
℃）, it is heat-resisting（150℃）, resistance to oxidation, resistance to ozone, all have many raisings than nitrile rubber in terms of weatherability and chemical-resistant reagent,
But there is defect on biological degradability.
The content of the invention
The defects of the object of the invention is exactly to make up prior art, widens waste paper and recycle being circulated through for approach
A kind of Ji, there is provided preparation method based on discarded bamboo pulp fiber paper and hydrogenated nitrile-butadiene rubber composites.
The present invention is achieved by the following technical solutions：
A kind of preparation method based on discarded bamboo pulp fiber paper and hydrogenated nitrile-butadiene rubber composites, comprises the following steps：
（1）After 40-50 parts by weight are discarded into the addition 100-110 parts by weight water high speed stirring of bamboo pulp fiber paper, 0.04- is added
