Active radical group is formed after the smooth initator in system of smooth solidify colophony draws radiant energy, not saturated Shuang Jian is contained in causing a system then or contain annulus the chemical reaction between the material of oxygen radical group, form the high polymer polymer of the stereo network structure of cross-linking. It is had volatilize without inert dissolvent, solidify time is short, but the advantage that the traditional solidify technology such as microtherm solidify cannot compare, call technology of new generation green. The smooth solidify technology of high polymer material serves as energy-saving with environmental protection technology, wide already application is enclosed in coating, printing ink, electron, adhesive, presswork industry of plank, electron, imperceptible treatment and shape quickly wait for a lot of domains to achieve rapid development and great progress. Year growth rate is as high as 25% , already formed a new industry. Introduce according to expert of net of not saturated colophony, ultraviolet light (UV) solidify coating is a kind of environmental protection that 60 time develop 20 centuries energy-saving coating, photograph of coating of as dry as traditional nature or hot solidify is compared, coating of ultraviolet light solidify has clear advantage, not saturated resinite fastens smooth solidify is his important system. Use at cultivating fat radical the solidify of composite material is this technology develop way newly again in recent years. One, foreword ultraviolet light (UV) solidify coating is a kind of environmental protection that 60 time develop 20 centuries energy-saving coating. Photograph of coating of as dry as traditional nature or hot solidify is compared, coating of ultraviolet light solidify has clear advantage, introduce according to expert of net of not saturated colophony, basically have: (1) solidify time is short, rate is rapid, can be inside tens of seconds solidify, can improve labor productivity greatly consequently, reduce workshop to cover an area of an area; (2) place is one ultraviolet light of ” of “ cold light with the sources of energy, do not need to heat compulsively dry, be helpful for cover with paint lumber, paper, plastic wait for the stuff with the old thermal capacity such as unfavorable heating material and concrete, thick plate; (3) does not have solvent or contain a few dissolvent, volatile is little, reduce air pollution; (4) is inside same time, it is about with energy consumption of place of ultraviolet light illuminate heat the 1/10 of 1000 dry; (5) improves film performance, especially burnish and exterior. But at present, homebred UV solidify coating all is dissolve the form of a drug, need to use active thinner monomer in great quantities, what this will bring about coating is organic volatilize constituent lifts considerably, with the increasingly strict coating VOC on international control code photograph is violated. Smooth solidify coating in 20 centuries 60 time throw industrial application formally already. Introduce according to expert of net of not saturated colophony, sensitive colophony is pressworking plate making and light send resist respect to already had delectable positive result, come out like what Kodak company synthesizes resist KPR Germany does obeisance to Er company to be opposite the behavior of ultraviolet light solidify of colophony of not saturated polyester and benzoic aether system undertook study, rolled out commercial product 1968 / fragrance Sijidaer (UV)100, this changes coating for Dai Guanggu. American Sun chemical company, Immont company developed acrylic acid to fasten smooth solidify printing ink 1970, developed coating of the acrylic solidify that fasten light very quickly then, call coating of the 2nd acting smooth solidify. Not saturated polyester is the colophony in coating of acting UV- smooth solidify. Introduce according to expert of net of not saturated colophony, its advocate Ma Lai acid or rich horse acerbity structure often are contained on catenary, among them Shuang Jian and vinyl monomer copolymerization form polymer network. After illuminate of ultraviolet light of classics of not saturated polyester, can form harder film, but flexibility and adherent force are bad, general and multi-purpose Yu Mu lacquer, the daub on a wall that is used at metal, plastic, paper is very few; Active thinner is commonly used styrene, boiling point is low, smooth solidify rate is slow. Accordingly, be necessary to undertake modified to system of not saturated polyester.
