Abstract
The invention discloses chlorinated linear low-density polyethylene. The synthesized low-density polyethylene comprises the following raw materials including polyethylene, process water, emulsifying agents, dispersing agents (A), dispersing agents (B), anti-sticking agents and initiating agents according to the weight ratio of 1:(5-20):(0-0.05):(0-0.5):(0-0.5):(0-0.4):(0-0.4). The chlorinated linear low-density polyethylene has the advantages that the corrosion rate and the reaction kettle pressure can be greatly reduced, and meanwhile, the quality of products is improved.
Description
Technical field
The present invention relates to a kind of chlorination LLDPE.
Background technology
Chlorinatedpolyethylene (be called for short CPE, CM) is by high density polyethylene(HDPE) (0.941～0.970g/cm3) product that makes at aqueous phase and chlorine reaction.It is a kind of special synthetic rubber, is again a kind of good plastic modifier.In October, 1973, Anhui Chemical Engineering Inst. began the research with water phase suspension chlorinatedpolyethylene technology; 06 month nineteen eighty-three, the kiloton industrialized unit built up; In November, 1984 is through two innings of technical evaluation of the Ministry of Chemical Industry; China's ultimate production is (wherein CPE output is that 400,000 tons, CM output are 100,000 tons) more than 500,000 tons now, is 7～8 times of Gross World Product.About 40 families of present national factory; Product is carried out chemical industry standard HG/T2704-2010; Along with having driven the chlorinated polyethylene rubber market requirement, China's rubber industry fast development sharply increases; Simultaneously because China's quality certification system, constantly improve the generally increase with enterprise-quality consciousness, market is also increasingly high to the requirement of the quality of CM, brand; Simply, the incompatibility rubber industry development of extensive style, single CM product, be badly in need of to chlorinated polyethylene rubber (CM) product carry out perfect, transform, innovation.
Summary of the invention
The present invention is directed to the problem in the background technology, researched and developed a kind of chlorination LLDPE, purpose is: improve the quality of products, reduce corrosion rate and reaction kettle pressure simultaneously greatly.
Technical solution of the present invention:
A kind of chlorination LLDPE is characterized in that: the starting material of said synthetic new LDPE (film grade) are Vilaterm, process water, emulsifying agent, dispersion agent (A), dispersion agent (B), release agent and initiator.
The weight proportion of said Vilaterm, process water, emulsifying agent, dispersion agent (A), dispersion agent (B), release agent and initiator is 1:5～20:0～0.05:0～0.5:0～0.5:0～0.4:0～0.4.
Said process water is deionized water or tap water.
Said emulsifying agent is the epoxy Viscotrol C.
Said dispersion agent (A) is a pyrrolidone.
Said dispersion agent (B) is a special silica.
Said release agent is a light calcium carbonate.
Said initiator is a superoxide.
Beneficial effect of the present invention:
The present invention can reduce corrosion rate and reaction kettle pressure greatly, improves the quality of products simultaneously.
Embodiment
Below in conjunction with embodiment the present invention is further specified.
Weight proportion according to Vilaterm, process water, emulsifying agent, dispersion agent (A), dispersion agent (B), release agent and initiator is that starting material are chosen in 1:5～20:0～0.05:0～0.5:0～0.5:0～0.4:0～0.4, makes chlorination LLDPE finished product through emulsification, chlorination, depickling, neutralization, dealkalize, centrifugal, dry, sieving technology step then.
