Description
Technical field
The invention belongs to chemical protection field, specially a kind of preparation method of low temperature resistant fluorubber coating fabric.
Background technique
Fluorubber has excellent physical mechanical property, medium-resistance and high temperature resistance, but cryogenic property is poor,
The lower limit of its holding elasticity is only -20 DEG C ~ -15 DEG C using temperature.Fluorubber coating fabric is usually used in chemical protection field, by fluorine
Protective garment made of rubber coated fabrics will appear the problem of hair deadlock is hardened in Han Qu use, gently then seriously hinder wearing personnel's
Operational action, it is heavy then remove glue-line and base fabric, it enables protective garment protection failed areas occur, can not ensure the operation of wearing personnel
Safety.
Therefore, existing fluorubber coating fabric cannot fully meet the use of the protective gear under diversified environment and need
It asks.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low temperature resistant fluorubber coatings that can be used safely in Han Qu to knit
Object, fluorubber coating fabric can be effectively improved the phenomenon that fluorubber hair deadlock is hardened at -25 DEG C.
The present invention is achieved by the following technical scheme:
A kind of low temperature resistant fluorubber coating fabric, the fluororubber layer coated including base fabric and scrim surfaces.Base fabric be it is any can
Textile fabric (such as aramid fiber) in conjunction with rubber, fluororubber layer includes each component of following parts by weight:
90 parts of fluorubber,
10 parts of fluoro silicone elastomers,
Bisphenol AF (molecular formula C15H10F6O2) 1.0 ~ 3.5 parts,
Accelerant B PP(benzyl triphenyl phosphonium chloride phosphine) 0.1 ~ 1.0 part,
Double -2,5(2,5- dimethyl -2,5- bis(t-butylperoxy) hexane) 0.05 ~ 0.1 part,
5 ~ 10 parts of calcium oxide,
2 ~ 5 parts of magnesia,
Permanent yellow (C34H30Cl2N6O6) 2 ~ 10 parts；
One, the mixing of fluororubber layer
This glue stuff compounding uses XK-160mm opening rubber mixing machine, friction ration 1:1.25.Preliminary roller roller when fluorubber is kneaded
Temperature is preferably 50 DEG C or so, and back roller roller temperature is slightly higher, and preferably 60 DEG C or so.Calendering process is as follows:
I, roll spacing is adjusted to 0.8mm, and raw rubber is added, enables its packet preliminary roller；
II, divide 5 addition fluoro silicone elastomers, be kneaded uniform；
III, roll spacing is adjusted to 1.2mm, and calcium oxide, magnesia is added, and is kneaded uniform；
IV, roll spacing is adjusted to 1.5mm, and permanent yellow is added, and is kneaded uniform
V, roll spacing is adjusted to 1.8mm, be added vulcanizing system (bisphenol AF, BPP, double -2,5), must control roller temperature (45 ~ 55 DEG C of roller temperature),
General three minutes；Every side cutter three times, general two minutes, arranges lower sizing material；
VI, roll spacing is adjusted to 0.8mm, and front and back is thin 5 times logical；
VII, last roll spacing is adjusted to required thickness, and slice is cooling.
Two, the preparation method of fluorubber coating fabric, comprising the following steps:
1, rubber cement is made in rubber compound and ethyl acetate 1:4 in mass ratio stirring obtained；
2, scrim surfaces frictioning method coats rubber cement, and unvulcanized fluorubber coating fabric is made；
3, unvulcanized fluorubber coating fabric is once vulcanized through drum vulcanizer or vulcanizing tank；
4, by the product after once vulcanizing through vulcanizing tank post-cure to get finished product.
Note: 151 DEG C × 25min of a vulcanization time；130 DEG C × 60min of post-cure time.
In the present invention, fluorubber coating fabric is mainly made of fluorubber, and fluorubber is a kind of in main chain or side chain
Polymer Synthesizing elastomer on carbon atom containing fluorine atom.Since the radius of fluorine atom is small, electronegativity is high make it have it is excellent
Different medium-resistance, fluorubber also has excellent physical mechanical property and high temperature resistance, but cryogenic property is poor,
The lower limit of holding elasticity is only -20 DEG C ~ -15 DEG C using temperature.Fluoro silicone elastomers are using methyl, trifluoro propyl polysiloxanes as base
The synthetic material of this structural unit, this structure composition oil resistant of fluorocarbon rubber, resistance to chemical corrosion and silicon rubber it is low
The excellent performances such as gentle soft, high temperature anti-tensile conservation rate.The bond energy of-Si-O-Si- key in its molecular structure is far longer than general rubber
The bond energy of glue-C-C- key, and the flexibility of strand is good.A certain amount of fluoro silicone elastomers are introduced in fluorubber, it can be effective
Improve the problem of fluorubber coating fabric hair deadlock is hardened under low temperature environment, while retaining the excellent medium-resistance of fluorubber.
Key point of the present invention is, introduces the resistance to low temperature that fluoro silicone elastomers improve fluorubber coating fabric.By fluorine rubber
Glue, fluoro silicone elastomers, calcium oxide, magnesia, bisphenol AF etc. are plasticated, are kneaded, and make to form rubber compound, and glue is made in rubber compound
Slurry is coated on scrim surfaces, after drum-type/pot type once vulcanizes, carries out post-cure in vulcanizing tank to get finished product.
Compared with the domestic prior art, the method for the present invention preparation fluorubber coating fabric guarantee physical mechanical property,
While medium-resistance, protective performance do not decline, the resistance to low temperature of fluorubber coating fabric is improved.
