Abstract
The invention is a kind of condensation bi-component conglutinating silicon rubber. The basic sizing is made up of end carboxyl poly dimethyl siloxane, reinforcement filler, normal filler, paint and functional filler. The cross linker and catalyst made up the firming agent. The alpha and gamma triple functional group, double functional group, silane resin acceptor made up the tackifier. 2-12 shares of firming agent and 1-8 shares of tackifier are added into 100 shares of base sizing. The invention also provides several kinds of surface processing agent which are made up of Nanjing University number 1, 2, 3, 4. The silicon rubber can be attached to the base. It can be used outdoor and damp place.
Description
The present invention is that a kind of condensed type double-component cements silicon rubber, is a kind of silicon rubber of self-vulcanizing, belongs to the silicon rubber technical field.
At present, similar condensed type double-component room temperature vulcanized silicone rubber is to be basic glue with hydroxyl-terminated injecting two methyl siloxane, add all kinds of reinforced fillings, increment filler, functional filler, pigment, softening agent, flow agent etc. selectively and carry out the mixing sizing that obtains, add linking agent and catalyzer before use more by a certain percentage.This glue can be cured to the darker degree of depth, and can regulate set time, and the user can add special functional material etc. as required.Can be used for coating and embedding than the components and parts of big area and certain depth.But above-mentioned glue exists and base material between cohesive force poor, easily throw off after the special water logging with base material, cause components and parts to meet behind the water no glue and protect and cause a series of serious consequences.
The object of the present invention is to provide a kind of can cementing, not influenced by water and can cement silicon rubber at the outdoor and moist local condensed type double-component of using with most of base materials.The surface treatment agent that the present invention also provides a kind of coated of going ahead of the rest on the difficult especially base material that cements to handle.
The objective of the invention is to be achieved through the following technical solutions.By end hydroxyl polydimethylsiloxane, reinforced filling, common fillers, pigment and the mixing base compound that is combined into of functional filler.Wherein sizing hydroxyl-terminated injecting two methyl siloxane consumption is 100 parts, add reinforced filling 3-30 part, other fillers 3-80 part, pigment 0.5-10 part, functional filler 3-200 part is carried out fully mixed mixing through three-roller again with above-mentioned each material and is just become base compound of the present invention 2-5 time.In 100 parts of linking agents, add catalyzer 1-20 part and be mixed with solidifying agent.Tackifier are formed by trifunctional, the two functional silanes coupling agent reasonable combination of α type and γ type.Adding 2-12 part solidifying agent and 1-8 part tackifier during use in above-mentioned 100 parts of base compounds fully stirs and just becomes the present invention to use product after mixed.The present invention also provides a kind of kinds of surface treatment agent of being made up of No. 1, No. 2, No. 3, No. 4 surface treatment agents of Nanjing University.
Sizing is also selected the hydroxyl-terminated injecting two methyl siloxane that has crosslinkable functionality on side chain for use except that selecting general hydroxyl-terminated injecting two methyl siloxane for use.
Reinforced filling is selected for use through organosilazanes R

Other fillers are selected a kind of in wollastonite powder, calcite in powder, lime carbonate, the silica powder or several for use.
Pigment is selected a kind of or several matched color in rouge and powder, bloom, green powder, blue powder, purple powder, black powder and the white powder for use.
Functional filler can be selected for use as required, can add silver powder, graphitized carbon black, silver-plated particle, carbon fiber or Graphite Powder 99 etc. when needing conduction, need can add oxyhydroxide, carbonate or antimonous oxide etc. when fire-retardant, fumed titanium dioxide can be added when needing antiultraviolet, ferric oxide and derivative or cerium oxide etc. can be added when needing heatproof.
