我国涂料辐射固化产业的发展现状

随着我国对环境、能源问题的日益关注，以及国民经济快速而平稳的发展，辐射固化技术得到了越来越广泛的应用。2007年我国辐射固化产业发展势头良好。受到世界各国辐射固化领域同行的密切关注。今后的几年，我国将节能减排作为发展工业最重要的考核指标，无疑，这对于发展辐射固化技术是一个契机。另一方面，由于电子加速器设备昂贵，我国电子束固化技术依然发展缓慢。但由于电子束固化所带来的独特优点，将会首先在食品包装、电子产品、航天航空、汽车制造等领域得到应用。 2006年，中国感光学会辐射固化专业委员会统计了129家主要的紫外（UV）固化产品生产企业的经济信息，其中原材料生产企业40家，紫外固化涂料生产企业81家，Uv光源和设备生产企业8家。相比2006年，2007年单体的产量相当，而出口超过1．6万t，增长100％；低聚物产量增长15．2％，并开始少量出口：光引发剂产量继续保持快速增长趋势，达到33.9％，出口超过总产量的70％。清漆和油墨保持12、1％和13．6％的年增长速率，粘合剂由于基数低，呈现出快速增长的势头．达73％。目前我国辐射固化产品市场的发展还不平衡．家具和印刷用紫外固化清漆涂层以及印刷品和包装材料用油墨仍是辐射固化技术最大应用领域。     

全球辐射固化材料近期市场分析（一）

辐射固化技术于20世纪60～70年代,在欧美市场上初步确立了自身的产业地位,成为全球经济体系中的一个组成部分.各种专业分工不同的企业（原材料生产供应商、化学配方产品生产供应商、装置设备制造供应商和下游客户）,共同构建了UV/EB固化产业的价值链.近年来,世界三大主要地区（北美、欧洲和亚洲）辐射固化市场以近两位数的速度在增长,尽管全球经济形势持续低迷.2012年,全球辐射固化市场配方产品的消耗量据统计大约为457000t.亚洲市场消耗量已超过欧美市场而居全球首位.辐射固化配方产品在世界三大主要地区市场中应用的重点领域虽然各不相同,然而工业涂料在全球的市场份额中仍然比例最大.本文还列出了辐射固化原材料在不同市场中的消费量与价格.

辐射固化的全球产业化与市场动态（二）

(上接本刊第19期)4市场动态辐射固化市场是辐射固化产品和服务的流通领域和交易场所。辐射固化市场自建立起就受到商品经济运动的普遍规律(供求规律、价值规律和竞争规律)的支配。辐射固化产品和服务正是通过生产、流通、交换、消费等环节完成整个交易过程。然而应当看到,生产决定流通,没有生产便没有流通,当然也就谈不上市场。反过来说也是正确的,没有流通,没有消费,生产也就失去了目的性。两者相互依存、缺一不可。因此可以简要的说,供给与需求的总和构成了辐射固化市场。从辐射固化产业价值链分析,辐射固化最重要的环节可以概括为两项,即…

Direct observation of freeze-thaw instability of latex coatings via high pressure freezing and cryogenic SEM

Despite its industrial importance, the subject of freeze-thaw (F/T) stability of latex coatings has not been studied extensively. There is also a lack of fundamental understanding about the process and the mechanisms through which a coating becomes destabilized. High pressure (2100 bar) freezing fixes the state of water-suspended particles of polymer binder and inorganic pigments without the growth of ice crystals during freezing that produce artifacts in direct imaging scanning electron microscopy (SEM) of fracture surfaces of frozen coatings. We show that by incorporating copolymerizable functional monomers, it is possible to achieve F/T stability in polymer latexes and in low-VOC paints, as judged by the microstructures revealed by the cryogenic SEM technique. Particle coalescence as well as pigment segregation in F/T unstable systems are visualized. In order to achieve F/T stability in paints, latex particles must not flocculate and should provide protection to inorganic pigment and extender particles. Because of the unique capabilities of the cryogenic SEM, we are able to separate the effects of freezing and thawing, and study the influence of the rate of freezing and thawing on F/T stability. Destabilization can be caused by either freezing or thawing. A slow freezing process is more detrimental to F/T stability than a fast freezing process; the latter actually preserves suspension stability during freezing.

Ethanol and (−)-α-Pinene: Attractant Kairomones for Bark and Ambrosia Beetles in the Southeastern US

In 2002–2004, we examined the flight responses of 49 species of native and exotic bark and ambrosia beetles (Coleoptera: Scolytidae and Platypodidae) to traps baited with ethanol and/or (−)-α-pinene in the southeastern US. Eight field trials were conducted in mature pine stands in Alabama, Florida, Georgia, North Carolina, and South Carolina. Funnel traps baited with ethanol lures (release rate, about 0.6 g/day at 25–28°C) were attractive to ten species of ambrosia beetles (Ambrosiodmus tachygraphus, Anisandrus sayi, Dryoxylon onoharaensum, Monarthrum mali, Xyleborinus saxesenii, Xyleborus affinis, Xyleborus ferrugineus, Xylosandrus compactus, Xylosandrus crassiusculus, and Xylosandrus germanus) and two species of bark beetles (Cryptocarenus heveae and Hypothenemus sp.). Traps baited with (−)-α-pinene lures (release rate, 2–6 g/day at 25–28°C) were attractive to five bark beetle species (Dendroctonus terebrans, Hylastes porculus, Hylastes salebrosus, Hylastes tenuis, and Ips grandicollis) and one platypodid ambrosia beetle species (Myoplatypus flavicornis). Ethanol enhanced responses of some species (Xyleborus pubescens, H. porculus, H. salebrosus, H. tenuis, and Pityophthorus cariniceps) to traps baited with (−)-α-pinene in some locations. (−)-α-Pinene interrupted the response of some ambrosia beetle species to traps baited with ethanol, but only the response of D. onoharaensum was interrupted consistently at most locations. Of 23 species of ambrosia beetles captured in our field trials, nine were exotic and accounted for 70–97% of total catches of ambrosia beetles. Our results provide support for the continued use of separate traps baited with ethanol alone and ethanol with (−)-α-pinene to detect and monitor common bark and ambrosia beetles from the southeastern region of the US.     

Methyl 2,4,6-decatrienoates Attract Stink Bugs and Tachinid Parasitoids

Halyomorpha halys (Stål) (Pentatomidae), called the brown marmorated stink bug (BMSB), is a newly invasive species in the eastern USA that is rapidly spreading from the original point of establishment in Allentown, PA. In its native range, the BMSB is reportedly attracted to methyl (E,E,Z)-2,4,6-decatrienoate, the male-produced pheromone of another pentatomid common in eastern Asia, Plautia stali Scott. In North America, Thyanta spp. are the only pentatomids known to produce methyl 2,4,6-decatrienoate [the (E,Z,Z)-isomer] as part of their pheromones. Methyl 2,4,6-decatrienoates were field-tested in Maryland to monitor the spread of the BMSB and to explore the possibility that Thyanta spp. are an alternate host for parasitic tachinid flies that use stink bug pheromones as host-finding kairomones. Here we report the first captures of adult and nymph BMSBs in traps baited with methyl (E,E,Z)-2,4,6-decatrienoate in central Maryland and present data verifying that the tachinid, Euclytia flava (Townsend), exploits methyl (E,Z,Z)-2,4,6-decatrienoate as a kairomone. We also report the unexpected finding that various isomers of methyl 2,4,6-decatrienoate attract Acrosternum hilare (Say), although this bug apparently does not produce methyl decatrienoates. Other stink bugs and tachinids native to North America were also attracted to methyl 2,4,6-decatrienoates. These data indicate there are Heteroptera in North America in addition to Thyanta spp. that probably use methyl 2,4,6-decatrienoates as pheromones. The evidence that some pentatomids exploit the pheromones of other true bugs as kairomones to find food or to congregate as a passive defense against tachinid parasitism is discussed.
