Description
Technical field
The present invention relates to a kind of addition-type silicon rubber packaging plastic and preparation method thereof, particularly a kind of single component strong cohesive property addition-type silicon rubber packaging plastic and preparation method thereof.
Background technology
The add-on type liquid silicon rubber sulfidation do not produce by product, shrinking percentage minimum, can deep layer vulcanization, elevated-temperature seal property is good, machine-shaping convenient, easily be automated production; It vulcanizes back high-low temperature resistant, UV resistant, radiation hardness, has electrical insulating property and physiology inertia.Thereby the add-on type liquid silicon rubber packaged material of making electronic devices and components commonly used, be used for preventing the influence of moisture, dust and obnoxious flavour to electronic devices and components, and the vibrations that slow down components and parts, thereby the protection electronic devices and components.But after the add-on type liquid silicon rubber sulfuration high saturated non-polar rubber; Main chain is made up of Siliciumatom and Sauerstoffatom; Side group is an organic group; The nonpolar organic group of one deck in the arranged outside of organosilicon polymer molecular backbone chain, molecular surface energy is very low, thereby poor to the body material adhesiveproperties.In order to guarantee electronic devices and components in harsh and unforeseen circumstances use properties down, the cohesive strength of needs raising itself and base material.
Electronic devices and components packaging plastic commonly used has single-component system and bicomponent system at present.The CN101280168A patent discloses a kind of mono-component organic silicone electron pouring sealant, and the characteristics of this patent are that the various one-tenth with joint sealant are distributed into single component, and the mixing process when avoiding product to use is saved time.But this kind mono-component organic silicone electron pouring sealant is inappropriate for the encapsulation place use that cohesive strength is had relatively high expectations.The CN101665623A patent discloses a kind of double-component addition self-adhesive silicon rubber; The characteristics of this patent are the ratios through vinyl and silicon hydrogen group in the control product; Make vinyl excessive, the unreacted vinyl in curing back makes the silastic surface after the sulfuration have good sticking power.But the excessive meeting of vinyl causes sulfuration not exclusively, and then influences the intensity and the high-temperature insulation electrical property of sulphurated siliastic.When using this double-component addition self-adhesive silicon rubber, need in advance two-pack to be mixed, time-consuming like this and might mix inhomogeneous.The CN101787256A patent discloses a kind of addition type silicone adhesive and preparation method; The characteristics of this patent are to use compound that organic hydrogen polysiloxanes and Rocryl 400 or Rocryl 410 prepared in reaction contain silicon hydrogen group and acrylic acid groups as linking agent; Silicon hydrogen group during sulfuration in the linking agent and the vinyl generation addition reaction in the vinyl silicone oil, the acrylic acid groups that contains can play cohesive action.But this tackiness agent directly uses and contains the linking agent of the ZGK 5 of acrylate group and silicon hydrogen group as vinyl silicone oil; Consumption is big; Be unfavorable for industrialization production (Yang Weisheng; Mao Xiaoli. Zylox is to the research of metlbond performance. Chinese tackiness agent .2000; 9 (6): 15-19), furthermore the acrylic acid groups that the contains insulated electro performance high-temperature insulation electrical property particularly that can reduce vulcanized rubber, therefore this silicone rubber adhesive is inappropriate for the demanding electron trade of insulating property and does the Electronic Packaging agent.Chinese literature (Xia Zhiwei; Liu Chaoyan; Li Xiaobing. the preparation of cohesiveness bi-component addition type liquid silastic. organosilicon material; 2007,21 (2): 81-84.) reported a kind of bi-component addition type liquid silastic, improved the cohesive strength of sulphurated siliastic through adding titanic acid ester tackifier with adhesive property.This is a kind of two-pack packaging plastic, needs when product uses in advance two-pack to be mixed.
Make a general survey of existing patent and document, wherein said addition-type silicon rubber packaging plastic is though perhaps be that single-component system sulfuration back is relatively poor with the adhesive property of base material; Perhaps be bicomponent system, need to mix two-pack before using.
