Description
Technical field
The present invention relates to a kind of waterstop and preparation method thereof, be specifically related to a kind of rubber fastening band and preparation method thereof.
Background technology
Along with the development of modern society, China's infrastructure construction further speeds up, building, subway, culvert, tunnel, dark
The engineerings such as canal, checkdam, cistern get more and more.And rubber fastening band is widely used in above-mentioned engineering, market is to waterstop
Propose the highest performance requirement.Currently, China has two: one to be GB/ about the standard of rubber fastening band
T18173.2-2014, another is TB/T 3360.2-2014, and alkali resistance solution index is proposed by latter of which clearly to be wanted
Ask.Therefore, how to improve waterstop physical index, improve processing characteristics, reduce cost simultaneously and be particularly important.
Chlorinated polyethylene be by the high density polyethylene (HDPE) of certain molecular weight through chlorination prepare chlorinity about 35%
The saturated elastomeric material of random chlorine distribution, ozone weather-proof, resistance to, ageing-resistant excellence.It is with neoprene (CR), ethylene-propylene-diene monomer
Glue (EPDM) performance approximates, the most alternative CR, EPDM, for manufacturing the specific rubber used under severe conditions
Goods, and cost is lower.At present, the effective vulcanizing system of chlorinated polyethylene mainly has peroxide vulcanizing system, thiourea cure
System and Thiadiazole Curing System.Wherein, Thiadiazole Curing System vulcanizing agent is expensive, usually the 6 of thiourea accelerator
About times, time of scorch is short in use, and commercial production is not easily controlled, and the sizing material holding time is the longest, limits it typically
Application in rubber industry.The domestic employing of thiourea curing system mostly be ethylene thiourea (accelerant N A-22), NA-22 toxicity
Relatively big, curingprocess rate is slow, is already belonging to the product that will be eliminated.The easy incipient scorch of peroxide vulcanizing system elastomeric compound, is not suitable for without mould
Sulfuration, vulcanizate hot tear strength is low, though high temperature compression is little, but normal temperature compressed permanent deformation is big, and producing during sulfuration stimulates
The acetophenone of property abnormal smells from the patient, can cause relatively bad influence to the working environment of workers, during pressing, through be commonly encountered choke with resentment, mould
The problems such as type pollution and the difficult demoulding, tasteless peroxide is expensive.Such as prior art CN201110456832.0 discloses
A kind of CPE rubber fastening band, described waterstop is using saturated rubber CPE rubber as base material, by rubber curing forming work
Skill preparation is formed, and in described formula, the mass ratio of each component is as follows: saturated CPE rubber 100 parts, softens plasticizer 20-
50 parts, heat stabilizer 2-8 part, pH value regulator 8-20 part, lubricant 1-5 part, reinforcing agent 25-60 part and cross-linking agent 3-10 part,
Described saturated CPE rubber uses chlorinty to be the chlorinated polyethylene rubber of 25wt.%-45wt.%.This invention is with chlorinated polyethylene
Alkene is material of main part, uses peroxide to make vulcanizing agent, and lead salt used as stabilizers and cross-linking agent etc. are prepared rubber fastening band, improve
Performance, reduces cost, meets waterstop standard GB/T/T 18173.2-2000, but examines alkali resistance solution index
Amount, is not suitable for waterstop standard TB/T 3360.2-2014；And the saturated CPE rubber production of peroxide systems crosslinking is more difficult
Controlling, compression set is big, and tearing toughness and liquid barrier capabilities are poor, and environmental-protecting performance is the poorest.
Summary of the invention
The technical problem to be solved is to provide a kind of low cost, environmental protection, processing characteristics is excellent, compression is permanent
Deform little, resistant to liquids penetrating power big, heat resistant oils and alkali resistance solution more preferably high-strength rubber waterstop and preparation method thereof,
This waterstop has excellent physical property, meets again two standards of rubber fastening band simultaneously.
The technical solution adopted for the present invention to solve the technical problems is, a kind of rubber fastening band, by following parts by weight
Raw material make, chlorinated polyethylene 100 parts, soften plasticizer 20～50 parts (preferably 20～40 parts), acid-acceptor 5～20 parts (excellent
Select 5～10 parts), lubricant 1～5 parts (preferably 2～4 parts), composite reinforcing agent 30～80 parts of (preferably 50～70 parts), sulfurate activities
Agent 1～5 parts (preferably 2～4 parts), vulcanization accelerator 2～10 parts (preferably 3～10 parts), sulfur 0.3～2.0 parts (preferably 0.5～2
Part).
Further, described softening plasticizer be di-n-octyl sebacate, dioctyl phthalate, trioctyl trimellitate (TOTM) and
One or more mixture in epoxy soybean oil.
Further, described acid-acceptor is magnesium oxide or magnesium hydroxide.
Further, one or more the mixture during described lubricant is Tissuemat E, paraffin and calcium stearate.
Further, described composite reinforcing agent is the one in white carbon black, white carbon, Kaolin, calcium carbonate and Pulvis Talci or two
Plant above mixture.
Further, described vulcanizing activator is zinc oxide and/or stearic acid.
Further, described vulcanization accelerator is Thiourea accelerator (preferably diethyl thiourea).
The present invention solves its technical problem further and be employed technical scheme comprise that, the preparation side of a kind of rubber fastening band
Method, comprises the following steps:
(1) by weight, by raw material chlorinated polyethylene 100 parts, soften plasticizer 20～50 parts, acid-acceptor 5～20 parts,
Lubricant 1～5 parts, composite reinforcing agent 30～80 parts, vulcanizing activator 1～5 parts, put in order in banbury refine glue 5～
10min, banburying temperature is 100～130 DEG C, returns glue 4～8min after binder removal on a mill until, and roll spacing is adjusted to 4～5mm and goes out film；
(2) gained film is added in banbury, addition vulcanization accelerator 2～10 parts and sulfur 0.3～2.0 parts mixing 1
～3min binder removal, temperature is 80～110 DEG C, returns glue 3～5min the most again in mill, is pressed into the semi-finished product film of lamellar；
(3) gained semi-finished product mixed sheet is molded into waterstop finished product by vulcanizer, wherein sulfide stress 8～
12Mpa, curing temperature 150～170 DEG C, cure time 15～20min；Or by extruding dies molding, through microwave vulcanization
It is shaped into rubber fastening band finished product.
The present invention uses vulcanization accelerator to be prepared into sizing material and is difficult to incipient scorch, stores the time long, and sulfuration is without bad smell, at mould
During stampings, easy-formation, do not choke with resentment, model pollutes and the problem such as the difficult demoulding, molded vulcanization can be simultaneously suitable for and squeeze
Going out two kinds of techniques of continuous vulcanization, processing characteristics is excellent.Moreover, use body material chlorinated polyethylene material price well below three
Unit's EP rubbers and neoprene, and operation of not plasticating, when manufacturing and apply, technological process is simple, can directly be processed into
Type, has lacked energy resource consumption significantly, shortens the process-cycle, is prepared into waterstop and has good resistance to ozone, ageing-resistant, low temperature resistant
The physical property that performance, high tensile and high-tear strength etc. are excellent；Meanwhile, it is not added with any stabilizer, age resistor just can expire
The standard-required of foot waterstop, and raw materials is general chemicals, does not use the toxic raw materials such as lead salt, produces, makes
During with more environmentally-friendly.
In brief, the present invention has low cost, environmental protection, processing characteristics is excellent, compression set is little, resistant to liquids infiltration
Ability is big, high tensile, anti tear, heat resistant oils and alkali resistance solution more preferably feature, can application factory etc. to sealing with
Particular/special requirement occasion.
