Description
Technical field
The present invention relates to a kind of dry-hang glue and preparation method thereof, be specifically related to a kind of stone material dry suspending glue and preparation method thereof.
Background technology
" cladding " generally refers to stone material basic unit Steel Skeleton, then constructional method Steel Skeleton being connected with stone material with stainless steel.The fluting position on stainless steel fixing stone bottom and top, and seal with structure glue joint filling, the structure glue of using is dry-hang glue.
Dry-hang glue is generally A, two groups of formations of B, and one group is mainly epoxy resin and stopping composition, and this is the main component of dry-hang glue; Another group is mainly solidifying agent and additive, and this is the component of cured resin.Two kinds of components, when not using, are liquid state, can solidification and crystallizations, in use, after will two groups of components mixing, just there is curing reaction.
In prior art; epoxy resin crystallization, can add or use more expensive modified epoxy conventionally in order to prevent because of temperature lower than zero degree, 170 resins of producing as Wuxi resin 830 and Taiwan; these resins all belong to bisphenol f type epoxy resin, and this has just increased production cost greatly.
Summary of the invention
Main purpose of the present invention is to provide a kind of low temperature resistant, stone material dry suspending glue that production cost is lower and preparation method thereof.
For achieving the above object, the technical solution used in the present invention is: a kind of low temperature resistant stone material dry suspending glue, described stone material dry suspending glue comprises Resin adhesive A and solidifying agent B, and Resin adhesive A is comprised of following parts by weight of component: 4～8 parts of E-44 epoxy resin, 8～15 parts of E-51 epoxy resin, 3～6 parts of thinners, 0.5～2 part of toughner, 50～65 parts, barium sulfate, 10～20 parts of dicalcium powders, 2～6 parts of light calcium carbonate powders.
Dicalcium powder is heavy calcium carbonate, is to be formed as calcite, marble, Wingdale grind by natural carbonate mineral; Light calcium carbonate powder is light calcium carbonate powder, that the raw material sections such as Wingdale are burnt and generated lime and carbonic acid gas, add again water digestion lime and generate milk of lime, pass into carbonic acid gas carbonization milk of lime and generate precipitation of calcium carbonate, through dehydration, dry and pulverizing, make, or by sodium carbonate and calcium chloride, carry out replacement(metathesis)reaction and generate precipitation of calcium carbonate, through dehydration, dry and pulverizing, make; Thinner is to coordinate basic mixed with resin to use, can reduce curing system viscosity, increase mobility, increase the service life, be convenient to large-area construction, when having improved operability, do not affect again the fundamental property of cured article, the convenient application for casting, perfusion, bonding, sealing, impregnating aspect; Toughner refer to can increase the flexible material of sizing agent rete, prevents after resin solidification that elongation reduces, becoming fragile makes glue-line cracking; Promotor is the material that improves resin system curing reaction speed, reduces solidification value; E-44 epoxy resin is to take the epoxy resin that diphenylol propane is 0.44 as chief component and average oxirane value; E-51 epoxy resin is to take the epoxy resin that diphenylol propane is 0.51 as chief component and average oxirane value.
Further preferred, described Resin adhesive A is comprised of following parts by weight of component: 5～7 parts of E-44 epoxy resin, 10～12 parts of E-51 epoxy resin, 3～5 parts of thinners, 1 part of toughner, 55～60 parts, barium sulfate, 12～18 parts of dicalcium powders, 3～5 parts of light calcium carbonate powders.
