The invention provides high-performance chlorohydrin rubber and a preparation method thereof. The high-performance chlorohydrin rubber comprises the following components in parts by weight: 55-65 parts of copolymerized chlorohydrin rubber, 30-50 parts of homo-polymerized chlorohydrin rubber, 25-40 parts of fast extruding furnace black N550, 15-30 parts of carbon black N330, 5-13 parts of a plasticizer, 0.2-2 parts of stearic acid, 0.5-3 parts of an antioxidant NBC, 4-15 parts of an acid accepter, 2-9 parts of calcium hydroxide, 1-3.5 parts of a demolding agent WS-180 and 3-13 parts of a vulcanizing agent, and all the components are subjected to the steps of weighing, plasticizing, mixing, re-sulfurization and the like to prepare the high-performance chlorohydrin rubber. The product overcomes the problems that the low-temperature performance is not good, the waste of raw materials is serious, the product quality is unstable and the like in the prior art, and green and environment-friendly chlorohydrin rubber with good high-low-temperature performances, good tensile strength and stable product quality is provided.
Description
Technical field
The present invention relates to rubber technology field, specifically refer to a kind of high-performance chlorohydrin rubber and preparation method.
Background technology
Rubber is the basic raw material of rubber industry, conventional rubber has good oil-proofness, thermotolerance, winter hardiness, resistance to pressure and water tolerance, resistance to air loss and good adhesive property, be widely used in manufacturing tire, sebific duct, adhesive tape, cable and other various rubber items.
Chlorohydrin rubber is owing to there not being two keys in molecular chain, therefore its heat-proof aging and ozone resistance are good, ehter bond because rotating in existing easily again, resistance toly circumnutate, elasticity is all good, side group chlorine atom provides the features such as the low and binding property of oil resistant, resistance to solvent, resistance to burning, ventilation property is good, over-all properties is better than paracril and chloroprene rubber, and price is lower than viton and silicon rubber.Because chlorohydrin rubber has above characteristic property, thereby application is very extensive, and permeates to more field: as automotive industry, petroleum industry, chemical fertilizer industry, refrigerating industry and medical material etc., all achieve good results.
Although chlorohydrin rubber has advantages of more, but also exist the problems such as poor processability, low-temperature performance are bad, unstable product quality, therefore the formulating of recipe of chlorohydrin rubber is an important topic of chlorohydrin rubber processing industry, especially the selection of vulcanizing agent is larger for the performance impact of goods.
Summary of the invention
The technical problem to be solved in the present invention is the deficiency that overcomes the problems such as prior art exists poor processability, low-temperature performance is bad, waste of raw materials is serious, unstable product quality, provide a kind of high temperature performance good, tensile strength is good, constant product quality, dielectric insulation performance is good, the chloropharin sebific duct of environmental protection.
For solving the problems of the technologies described above, technical scheme provided by the invention is:
A kind of high-performance chlorohydrin rubber, its component and weight part are:
Further, acid-acceptor is Magcler1, and Magcler1 is that Japanese KYOWA company produces, and is widely used in various halogen-containing synthetical glues.Can substitute plumbous oxide, magnesium oxide and make that vulcanization rate is fast, state of vulcanization is more complete.
Further, described vulcanizing agent comprises:
A preparation method for high-performance chlorohydrin rubber, described chlorohydrin rubber is prepared from by following steps:
(1) weighing: according to copoly type chlorohydrin rubber, homopolymerization type chlorohydrin rubber, extrude carbon black N550, carbon black N330, softening agent TP759, stearic acid, antioxidant NBC, acid-acceptor, calcium hydroxide, releasing agent WS-180 soon, vulcanizing agent umber is separately stand-by after taking;
(2) plastic cement: block blob of viscose is processed into in small, broken bits in mill, controls the temperature of plastic cement below 55 ℃, the time is between 8～18min;
(3) mixing: the fast extrusion carbon black N550, carbon black N330, softening agent TP759, stearic acid, antioxidant NBC, acid-acceptor, calcium hydroxide, the releasing agent WS-180 that weigh up in the thin blob of viscose of processing by step (2) and step (1) are mixed together in and in internal rubber mixer, refine glue;
(4) return sulphur: will further add load weighted vulcanizing agent in step (1) to mix sulfuration through step (3) blend glue stuff after treatment, and control temperature between 50～95 ℃.
Adopt after technique scheme, tool of the present invention has the following advantages: 1) utilize the chloropharin sebific duct that chloropharin sizing material of the present invention produces can life-time service at 180 ℃, even use and still have good elasticity, and have good high and low temperature resistance at-60 ℃.
2) utilize the dielectric insulation performance of the chloropharin sebific duct that chloropharin sizing material of the present invention produces fabulous, especially the dielectric properties under high temperature substantially exceed general organic rubber pipe, and dielectric strength is subject to hardly the impact of temperature within the scope of 20-180 ℃.
3) in formula of the present invention, substitute plumbous oxide with acid-acceptor Magcler1: in halogen synthetical glue formula, plumbous oxide can greatly improve thermal stability and water tolerance, but plumbous oxide is also very big to the harm of environment.And that Magcler1 has environmental influence is little, thermal stability and water tolerance effect are large, very environmental protection and can improve thermal stability, thereby can substitute plumbous oxide completely.
4) thermotolerance that substitutes magnesium oxide: Magcler1 with acid-acceptor Magcler1 in formula of the present invention is far above magnesium oxide.And acid-acceptor Magcler1 has passed through EU and FDQ authentication security is nontoxic.
