Description
Technical field
The invention belongs to chemical field.
Background technology
Because the general purpose polystyrene quality is hard and crisp, physical strength is not high, thermotolerance is relatively poor; So people have carried out modification work; Progressively formed present high-impact polystyrene (HIPS); It owing to contain the rubber phase component in the matrix, increases the toughness of high-impact polystyrene mainly by the two-phase system of forming as the external phase PS and the disperse phase rubber of matrix widely.Because it is with low cost, be easy to processing and painted, high rigidity, dimensional stability is good; High glossiness; Be a kind of application thermoplastics very widely, for example wrapping material, disposable product, instrument, household electrical appliance, toy amusement article and building trade etc.
High-impact polystyrene is invented by Ostromislensky, and obtains commercialization in the 1950's.Working method comprises two kinds of mechanical blending method and grafting copolymerization processes:
1, the composition of mechanical blending method: HIPS is the blend of PS PS and rubber polymer, and rubber polymer mainly contains styrene butadiene rubber sbr, styrene-butadiene-styrene multipolymer (SBS) etc.The HIPS that the styrene butadiene rubber sbr blend of PS and 8～10 parts makes, shock strength improves 2 times, anti-impact grade in belonging to; The product of PS/SBR/SBS tertiary blending then is a superelevation anti-impact grade, and the glossiness of product surface is high.
2, grafting copolymerization process: at first that consumption is about 10 parts polybutadiene rubber is dissolved in the vinylbenzene, adds the initiator Lucidol, and body or suspension graft copolymerization are carried out in heating.The first step is the chain transfer reaction of trunk polyhutadiene, and this is that elementary radical R by decomposition of initiator proposes H-H reaction and forms high molecular free radical, and the position of carrying hydrogen is an allylic Wasserstoffatoms on the trunk.Second step of graft copolymerization is that the high molecular free radical on the trunk causes styrene polymerization, if it and elementary combined with radical just stop the branched PS of formation.
At present; The HIPS poly-unit of domestic introduction adopts continuous bulk technology basically; The most advanced world production technology has the technologies such as TEC-MTC of DOW chemistry, Fina, Chervon&Huntsman, German BASF and the Japan of the U.S. now, and is wherein advanced with the technology of DOW chemistry.
For the method for preparing high impact polystyrene; U.S. Fina Technology has international patent of invention WO2005/033176; It has used the high-impact polystyrene of blended initiator preparation; Mixed rubber and styrene monomer, and make styrene polymerization, initiator comprise at least a grafting initiator and a kind of non-grafting initiator.The high-impact polystyrene that makes has the continuous polystyrene phase and is dispersed in rubber grain wherein, and these rubber grains mainly have the rubber polynuclear plane that comprises polystyrene inclusions.
Modified rubber impact-resistant polystyrene resin compsn (CN1519269) has been invented by Co., Ltd. of Ube Industries Ltd.; They utilize contains the rubbery polymer rubber modified polystyrene resin; Wherein rubbery polymer is under transition-metal catalyst exists high-cis-high vinyl polybutadiene modification to be obtained, and still obtains the high impact polystyrene resin through the continuous bulk polymerization subsequently.
The Institute of Beijing Yanshan Petrochemical Co., Ltd., Sinopec Corp has Chinese invention patent CN1609126; It relates to a kind of ultrahigh impact strength polystyrene resin and preparation method thereof; Employing is dissolved in the mixture of divinyl, isoprene, styrene copolymer or several kinds of divinyl, isoprene, styrene copolymer in the vinylbenzene, prepares the ultrahigh impact strength polystyrene resin through free radical reaction.The butadiene content of the polystyrene resin of gained is 1-20 part (weight percent), and isoprene content is 1-20 part (weight percent), and styrene content is 75-97 part (weight percent), and its erosion-resisting characteristics is improved significantly.
For present preparation high-impact polystyrene technology; Owing to used the bulk graft polymerization method; With rubber directly dissolve with styrene monomer in; Polymerization system viscosity subsequently increases greatly, has caused the maximum rubber content of product to be restricted, and is difficult to address this problem through present existing technology.
Changchun applied chemistry institute has Chinese patent CN1083079, and the high-impact polystyrene of having introduced a kind of modification is by high-impact polystyrene, cis-1,4-polybutadiene rubber or styrene-butadiene rubber(SBR), styrene-butadiene-styrene block copolymer, compositions such as light calcium carbonate.At first with light calcium carbonate with the rubber uniform mixing, pelletizing is combined in the double-spiral bar extrusion with other then and mixes, the gained modified high impact resistant polystyrene has high shock strength, higher modulus in flexure and low cost.But a little less than the simple mixed and modified interface ability that causes various raw materials, cause performance of products to be affected.
Summary of the invention
The objective of the invention is to utilize graft polymerization technique; With rubber particles surface grafting polystyrene material; Increased the interface binding power between rubber particles and the polystyrene resin; Thereby make performance of products stable, cause the preparation method of the toughness reinforcing superhigh tenacity polystyrene resin that increases considerably of product.
The concrete preparation process of the present invention is following:
(1) utilizes emulsion grafting polymerization technology, the particle grafted PS powder of synthesizing polybutadiene rubber;
