Abstract
The present invention relates to a colorless transparent silicone rubber crosslinking curing agent. The curing agent is prepared by mixing gamma-propylamino propyl trialkoxyl silane, alpha-propylamino methyl trialkoxyl silane and dimethyl diethyl silane in a certain proportion. The room temperature curing silicon rubber with a single component, which is prepared by mixing the crosslinking curing agent of the present invention with base rubber in a certain proportion at a room temperature, has the advantages of high curing speed, high storage stability, nontoxicity, no pollution, no colors, transparence, no color distortion along with time change, etc. The present invention is especially suitable for occasions needing optical transparency, such as occasions of optical instruments, video equipment, automobile lamps, searching lamps, focus lamps, isolators of high voltage transmission lines, high voltage electrical equipment, etc.
Description
Affiliated technical field
The present invention relates to a kind of dealcoholizing-type single-component self-vulcanizing (RTV) silicon rubber, particularly a kind of colorless transparent silicone rubber crosslinking curing agent.
Background technology
The look change can take place in dealcoholizing-type single-component self-vulcanizing (RTV) silicon rubber along with the prolongation of shelf-time at present, yellow even deep yellow by colourless commentaries on classics, but when reality was used, particularly the insulator of some optically transparent occasion of needs such as opticinstrument, shade equipment, automobile lamp, searchlight, spot light lamp, ultra-high-tension power transmission line and high-voltage electrical equipment etc. needed to adopt water white silicon rubber.Optical clarity be will influence because the look of silicon rubber becomes, and the electrical insulation properties and the physicals of silicon rubber also can be influenced after the look change.And curing speed, the package stability of single-component self-vulcanizing (RTV) silicon rubber, pollution-free, corrodibility and electrophysics performance thereof etc. are arranged particularly whether look becomes with its used crosslinking and curing agent very big relation is arranged.So look does not take place if want the silicon rubber water white transparency to be become it to close chain is to make a kind of good water white transparency and crosslinking and curing agent that can the look change.
Summary of the invention
The objective of the invention is to produce a kind of silicone rubber crosslinking curing agent.The dealcoholizing-type single-component room curing silicon rubber curing speed that is mixed with this crosslinking and curing agent is fast, excellent storage stability, nontoxic, pollution-free, water white transparency and look can not take place along with the variation of time become.
Technical scheme of the present invention is as follows: a kind of colorless transparent silicone rubber crosslinking curing agent of the present invention is to be followed according to certain proportioning by γ-Propylamino propyl trialkoxy silane, α-Propylamino methyl trialkoxysilane and dimethyldiethoxysilane to be mixed and to make.Product of the present invention and basic glue at room temperature are mixed by a certain percentage, and its proportioning consumption is by weight when producing silicon rubber: 100 parts in basic glue, γ-Propylamino propyl trialkoxy silane 1-1.5 part, α-Propylamino methyl trialkoxysilane 4-5 part and dimethyldiethoxysilane 5-6 part.
The silicon rubber that is mixed with product of the present invention and basic glue has following advantage: curing speed is fast, excellent storage stability, nontoxic, pollution-free, water white transparency and look can not take place along with the variation of time become.
Embodiment
With viscosity is that 107 silicon rubber of 20000Pa.s are basic glue.
In dry nitrogen atmosphere, get 100 parts in above-mentioned basic glue, 1 part of γ-Propylamino propyl trialkoxy silane, 4 parts of α-Propylamino methyl trialkoxysilane pour in the metallic hose sealing and preserve after 5 parts of configurations that at room temperature are mixed of dimethyldiethoxysilane are mixed well.
After 10 days glue is extruded from metallic hose when placing air, observed it and be the water white transparency colloid.Store after six months glue extruded from metallic hose and place air, solidified the rear surface in 10 minutes, and it still be the water white transparency colloid, and the look change does not take place this glue over time.
