Description
Technical field
The present invention relates to a kind of haloflex-blend rubber waterproof roll, and in particular to a kind of haloflex-ternary
Waterproof roll is blended in EP rubbers.
Background technology
Ethylene propylene diene rubber (EPDM) has excellent water resistance, heat-resisting cold resistance and excellent weatherability, ozone resistance
Can, therefore ethylene propylene diene rubber is widely used in the industries such as automotive sealant, waterproof roll, electric wire.But due to ternary
EP rubbers double bond content is relatively low, without polarity side base so that ethylene propylene diene rubber curingprocess rate is slow, mechanical property is not high and
Tack and mutual viscosity are poor.These deficiencies based on ethylene propylene diene rubber, carry out blending and modifying, to carry to ethylene propylene diene rubber
Its high curingprocess rate, improves mechanical property.
Haloflex (CPE) excellent fireproof performance, resistance to ozone and decay resistance protrude, meanwhile, with ethylene-propylene-diene monomer
Glue is consistent, and molecular backbone is saturated structures, therefore both are used in combination, and have preferable intervulcanizability.Simultaneously as EPDM
The high filling characteristic of rubber, EPDM/CPE and use can make up the shortcomings that ethylene propylene diene rubber price is higher, Domestic Product is insufficient,
Effectively reduce the production cost of product.But the haloflex of existing formula system-ethylene propylene diene rubber blending waterproof roll
Low temperature flexibility need further to improve.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of haloflex with excellent low temperature flexibility-ternary second
Third blend rubber waterproof roll.
Haloflex of the present invention-ethylene propylene diene rubber blending waterproof roll, by weight, by following components
It is made：

1：1 weight is than composition；
Age resistor 1-3 parts；
Wherein, described modified meerschaum is prepared as follows：α sepiolites are taken, crushes, is 1- with mass concentration
1.5% lime solution is soaked 7-10 days, filtering, filter residue and drying, is crushed, that is, is obtained modified meerschaum.
In above-mentioned technical proposal, the weight proportion of each component is preferably：
Haloflex 75-80 parts；
Ethylene propylene diene rubber 20-25 parts；
Modified meerschaum 10-15 parts；

In the method for preparing modified meerschaum that above-mentioned technical proposal is related to, the lime solution is by according to concentration requirement
A certain amount of quick lime is placed in water dissolving and obtained.The addition of the lime solution is 10-15 times of α sepiolite weight,
Preferably 10-12 times of α sepiolites.α sepiolite powders are typically broken to 60-100 mesh, then add lime solution immersion；Typically will
The filter residue that gained is soaked, filters, dried through lime solution is crushed to 80-120 mesh.Special modification is carried out to sepiolite,
Sepiolite can be effectively purified, so as to effectively improve the characterization of adsorption of gained modified meerschaum.Gained modified meerschaum is added
Into haloflex-EPDM Blends, it has a good dispersiveness, and with haloflex and ternary second
Extremely strong affinity is respectively provided between third rubber, then coordinates specific vulcanizing system to obtain the low temperature flexibility of gained waterproof roll
Effectively improve.
In above-mentioned technical proposal, the selection of the filler is same as the prior art, can be specifically to be selected from lightweight carbonic acid
Combination more than one or both of calcium, powdered whiting and talcum powder.
In above-mentioned technical proposal, the selection of the softening agent is same as the prior art, can be specifically aromatic naphtha, paraffin oil
With combination more than one or both of pitch.
In above-mentioned technical proposal, the accelerator is selected from captax (2- thiol benzothiazoles), accelerator CBS (N-
Cyclohexyl-2-benzothiazole sulfonamide) and accelerator TT (tetramethylthiuram disulfide) in a kind of two or more group
Close.
In above-mentioned technical proposal, the selection of the age resistor is same as the prior art, can be specifically antioxidant 4010NA
(N- isopropyls -4-aminodiphenylamine) and/or anti-aging agent RD (2,2,4- trimethyl -1,2- dihyaroquinoline condensate).
Waterproof roll is blended by existing conventional method system in haloflex of the present invention-ethylene propylene diene rubber
It is standby.
Compared with prior art, the present invention is passed through by being added in haloflex-EPDM Blends
Modified meerschaum obtained by special modification is good in haloflex-EPDM Blends using it
Dispersiveness, and its have between haloflex and ethylene propylene diene rubber extremely strong affinity the characteristics of, then coordinate specific
Vulcanizing system make gained waterproof roll low temperature flexibility effectively improve, can reach less than -50 DEG C；On the other hand, also make
The viscosity of elastomeric compound is improved, and further lifts the intervulcanizability of haloflex and ethylene propylene diene rubber.
