2. in such scheme, described Nano-meter SiO_2 2powder mean diameter is 12nm.
3., in such scheme, described solvent is solvent is butanone, ethyl acetate or toluene.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1. solvent-borne type of the present invention strong viscous force pressure-sensitive adhesive agent, it adopts nano level and micron order SiO 2powder Al 2o 3powder and methyl methacrylate 70 parts, ethyl propenoate 26 parts, dimethyldiethoxysilane 15 parts and silane coupling agent, isocyanic ester acting in conjunction, relatively single use nano level or micron order SiO 2powder, Al 2o 3powder, improves vinylformic acid sizing agent roughness, is also conducive to SiO 2powder, Al 2o 3powder is uniformly distributed and dispersion in system, avoids cluster; Secondly, azo-compound 1.5 parts, adding of N-nitroso compound 4.6 parts, it also avoid SiO 2powder, Al 2o 3the sedimentation of powder in system, improves and base material bonding force.
2. solvent-borne type of the present invention strong viscous force pressure-sensitive adhesive agent, it comprises Gum Rosin 4.2 parts, and note olefine resin 4.5 parts and methyl methacrylate 70 parts, ethyl propenoate 26 parts, dimethyldiethoxysilane 15 parts of actings in conjunction, avoid by SiO 2powder, Al 2o 3powder adds the decline of the resistance to elevated temperatures caused, and improves resistance to elevated temperatures, and the stability of viscosity under difference variation, thus improves the reliability of product.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
Embodiment: a kind of solvent-borne type strong viscous force pressure-sensitive adhesive agent, the agent of described solvent-borne type strong viscous force pressure-sensitive adhesive is made up of following parts by weight of component: methyl methacrylate 70 parts, ethyl propenoate 26 parts, dimethyldiethoxysilane 15 parts, solvent 40 parts, nano level SiO 2powder 2.8 parts, nano level Al 2o 3powder 1.2 parts, micron order SiO 2powder 0.2 part, micron order Al 2o 3powder 0.4 part, isocyanic ester 0.8 part, Gum Rosin 4.2 parts, note olefine resin 4.5 parts, azo-compound 1.5 parts, N-nitroso compound 4.6 parts, silane coupling agent 1.2 parts;
