Description

Trielement ethyl butyric rubber waterproofing coiled material and production method thereof

Technical field

The present invention relates to a kind of waterproof roll and production method thereof, particularly trielement ethyl butyric rubber waterproofing coiled material and production method thereof.

Technical background

At present rubber water-proofing coiled production method is general uses traditional rubber drum-type to vulcanize or pressure-pot sulfurized one step cure method, it is the plane that one step cure makes the product die mould, and the surface does not produce decorative pattern, and the specific surface area of adhesive face is little, and present explained hereafter cost height, The comprehensive performance is low.

Summary of the invention

Purpose of the present invention promptly is to overcome the shortcoming of prior art, and a kind of good weatherability is provided, and is not subjected to the trielement ethyl butyric rubber waterproofing coiled material and the production method thereof of high low temperature limitation, its good percentage elongation, anti-aging Z-TEK is strong, by the effect of light, can reach the best antiageing effect of natural vulcanization.

Purpose of the present invention is achieved through the following technical solutions: trielement ethyl butyric rubber waterproofing coiled material, and the proportioning raw materials of waterproof roll is:

Terpolymer EP rubber EP35 or 4045 80-120;

Butyl reclaimed rubber material 80-120;

Carbon black 50-80;

Fine particle calcium carbonate 80-120;

ZnO 3-8；

Stearic acid 0.8～1.5;

Captax 0.5～1;

Promotor TE 1～2;

Promotor TT 0.8～1.5;

Promotor PZ 1～1.5;

Microcrystalline Wax 1～3,

Paraffin oil, naphthenic oil 15～25;

S 1.5～2.5。

The production method of trielement ethyl butyric rubber waterproofing coiled material, the step of production method is as follows:

(1) cooperates: by above proportion ingredient;

(2) mixing: pressure: 0.4～0.5Mpa, 100～110 ℃ of temperature, the time is 12min, adds raw material to be in proper order, Ethylene Propylene Terpolymer EP35 or 4045, after adding butyl reclaimed rubber material 1.5min, add ZnO, stearic acid, captax, TE, TT, PZ 1.5min again after, add carbon black, fine particle calcium carbonate then, add Microcrystalline Wax, paraffin oil behind the 4min, naphthenic oil, binder removal behind the 5min, mill adds sulphur;

(3) heat refining: 50～55 ℃ of roller temperature, three triangle bags of three thin-passes, two sections heat refining slices of roll spacing are adjusted in the back;

(4) rolling out film: roll spacing is decided 45～55 ℃ of temperature by product specification;

(5) one section die mould sulfuration of drum-type: the pressure 0.8～1.2Mpa of drum vulcanizer, linear velocity 2～3m/min, 150～180 ℃ of temperature;

(6) tank type vulcanizing: the vulcanizing boiler that post vulcanization adopts thermal oil to heat up, cure conditions is air pressure 0.3～0.4Mpa, and temperature is 150～180 ℃, and the time is 1～3h;

(7) test package warehouse-in.

By top narration as can be seen, the present invention has the following advantages: waterproof, protection against the tide, mildew-resistant; Chemical corrosions such as withstand voltage, acid-and base-resisting, salt, strong adhesion, good percentage elongation, anti-aging extra-heavy, production method of the present invention organically combines former traditional rubber drum-type sulfuration and pressure-pot vulcanization process, the change one step cure is post vulcanization, one step cure makes the product die mould, the surface produces different required decorative patterns, to increase the specific surface area of adhesive face, increases the visual appearance of product simultaneously.The present invention has improved the performance of product, has improved productivity, has reduced production cost and equipment cost, simultaneously energy efficient.The present invention's prescription is the main body except that adopting special Ethylene Propylene Terpolymer prescription, also mixes self-control butyl reclaimed rubber material, and the The comprehensive performance that this not only improves reduces production costs simultaneously, meets country and encourages to use regeneration to reclaim the industry policy of waste material.

Following table is the survey report that relevant authoritative inspection department is done leading indicator of the present invention:

Project	Index	Assay
			Fracture tensile strength Mpa 〉=	3.0	5.9
Tensile yield % 〉=	200	492
			Tear strength kN/m	10	19
Watertightness 0.2Mpa, 30min	Waterproof	Qualified
			Low-temperature bending-20 ℃	Flawless	Qualified

By the table in as seen: fracture tensile strength of the present invention, tensile yield and tear strength all are significantly improved, and watertightness and low-temperature bending have all reached relevant national standard.
