Fill RTV silicon rubber and preparation method.
Background technology
Silicon rubber is macromolecule of the class with Si-O-Si as main chain, with excellent high-low temperature resistant, weatherability, resistance to ozone,
Dielectric properties and the features such as be independent of petroleum resources, it is many in Aero-Space, automobile mechanical, electric and biologic medical etc.
Field has a wide range of applications, and is indispensable family macromolecule material in national economy.
Calcium carbonate is the main stuffing of one-pack RTV silicone rubber sealant, generally plays extender filler, that is, increase
Product volume reduces cost, with the fast development of nanometer technology, the particle diameter of calcium carbonate can reach Nano grade (particle diameter<
100nm) as other Nano fillings, nanometer grade calcium carbonate powder also has certain strengthening action.But due to Nano filling
With too high specific surface area and surface energy, easily reunite during material is prepared, so that the performance of product can not reach
To Expected Results.
Nano-calcium carbonate is not directly added into silicon rubber generally, but carries out surface by surface conditioning agent (such as coupling agent)
Treatment, with its surface formed coat, between nano particle formed intercept, reduce nano particle reunion degree, improve its
The dispersiveness of rubber.Current calcium carbonate is fatty acid modifying agent using most surface modifiers, although fatty acid
Modifying agent can reduce the reunion between calcium carbonate particle, but the surface treatment using aliphatic acid to calcium carbonate is unfavorable for material power
