Description
Technical field
The invention belongs to rubber composite preparing technical field, and in particular to a kind of cotton pulp short-fiber rubber composite material
Preparation method.
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, fibre property is improved, is elastomeric material hair by fiber composite
One of inexorable trend of exhibition.
China is that the fiber such as rubber industry big producer, tire, conveyer belt, sebific duct/rubber composite is important army
The dual-purpose product of the people, and high-performance fiber is the preferable framework material of rubber, but current high-performance fiber is in rubber
Application do not popularize yet.And influence orientation that principal element that fiber applies in rubber is fiber in rubber mass,
Scattered and between fiber and rubber mass interfacial adhesion is horizontal.
The content of the invention
According to problems of the prior art, the invention provides a kind of preparation of cotton pulp short-fiber rubber composite material
Method so that fiber disperses more uniformly in rubber mass, and further increases fiber and the interfacial adhesion of rubber mass
It is horizontal.
In order to solve problems of the prior art, the present invention uses following technical scheme：
A kind of preparation method of cotton pulp short-fiber rubber composite material, comprises the following steps：
Step 1：The vacuum drying oven that cotton pulp chopped fiber is placed at 80 DEG C dries 24 hours to remove moisture, 250ml's
In flask, cotton pulp chopped fiber after 2.5g is dried is added, then pours into 120ml acetic anhydrides in flask, adds 0.5g sodium carbonate, will
Flask is placed in heating response in 150 DEG C of oil baths, and acetylization reaction reacts 90 minutes at reflux, after reaction terminates, with third
Ketone cleans to reaction product, reuses acetone as solvent and carries out soxhlet type to remove generated acetic acid and unreacted
Acetic anhydride, after finally fully being cleaned to product using deionized water, then be placed in the vacuum drying oven at 60 DEG C dry 24 hours,
It is stand-by；
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, 5 parts of cotton pulp chopped fiber, zinc oxide 3
Part, 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, 30 parts of white carbon, sulphur 1.2
Part；Natural rubber is added in mill and is kneaded, adds other dispensings after Natural rubber bag roller, charging sequence according to
Secondary is zinc oxide, stearic acid, accelerator, age resistor, white carbon, sulphur, is eventually adding cotton pulp chopped fiber；
Step 4：Triangle bag is beaten, after fiber is uniformly dispersed, adjusts roller square, to fiber be orientated then bottom sheet, is made
Elastomeric compound 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, the length of described cotton pulp chopped fiber is 0.6-1.0mm.
The beneficial effects of the present invention are：
1) cotton pulp Short Fiber/rubber Composites are by fiber and rubber mix, and are allowed to be suitably oriented in rubber matrix,
To play the strengthening action of chopped fiber, so as to effectively combine the flexibility of rubber and the rigidity of fiber.Ensureing that it is only that rubber has
While extra-high elastic, the modulus of rubber is improved, it is possessed high-modulus, high rigidity, tear-resistant, cut resistant, low-heat-generation, anti-
The a series of excellent properties such as creep, so as to greatly widen the use range of rubber.
2) acetic anhydride process is carried out to cotton pulp chopped fiber, to reduce the hydrophily of cotton pulp chopped fiber, so as to improve cotton pulp
Compatibility between chopped fiber and rubber matrix, improve the interface binding power between cotton pulp chopped fiber and rubber matrix.
