Description
Technical field
The present invention relates to mould release technical fields more particularly to a kind of emulsion-type mould release and preparation method thereof.
Background technique
Silicone release agent is also known as paper release silicone, is to be coated on specific substrate (such as paper, film etc.) to pass through
Certain curing reaction, one layer of formation has the coating of isolation, anti-sticking and other effects.It is said on stricti jurise, silicone release agent
It is regarded as a kind of using organosilicon as the coating of film forming matter.Claimed after paper or the coated cured silicone mould release of film
It for release paper or release film, is applied with very extensive market, whether label, adhesive tape, show and colour or medical
Fields, release paper or the release films such as product, amenities, food processing packaging, express envelope and electronic die patch are in protection adhesive
It is all played in terms of from polluting, facilitating production and processing, facilitate the physical property of product such as storage and transport, holding adhesive important
Effect.
There are many product form for silicone release agent, and also there are many classification methods.Divide from product appearance state, can divide
For no-solvent type, solvent type and emulsion-type three categories；Can be divided into from curing mechanism heat cure (containing solvent type, no-solvent type and
Three kinds of states of emulsion-type) and UV/EB radiation curing (no-solvent type state) two major classes, the product of heat cure is from polymerization machine
It is divided into organotin catalyzed condensation curing reaction system (containing three kinds of solvent type, no-solvent type and emulsion-type states) and platinum in reason again
Gold or rhodium etc. catalytic additions solidification polymerization reaction system (containing three kinds of solvent type, no-solvent type and emulsion-type states) two major classes.
Solvent type mould release product can largely utilize toluene and industrial naptha in the production of mould release producer and client's use
Etc. diluent is made, this kind of product is caused to always exist the hidden danger and realistic problem of safety in production and environmental pollution；Especially make
With the client of mould release, fire incident caused by often occurring in coating process because of electrostatic, to the wealth of coating producer
It produces and personal safety all causes very big loss.And in coating process, if the solvent of Macrodilution without recycle or
Effectively recycling is just discharged into air, both polluted the significant wastage that environment is also resource.
A kind of mould release product of the emulsion-type silicone release agent as safety and environmental protection, be the substitution of solvent based product more
One of new product.But emulsion type products be using water as carrier, compared with solvent based product storage stability, reaction curing rate,
It is all insufficient in terms of the physical property such as spreadability and anchoring on substrate.
