Butylbenzene class latex is a kind of high molecular polymer.Since its own partial size is smaller (90nm -140nm), using lotion
The particle diameter distribution for the polymer beads that the mode of polymerization obtains is also relatively uniform.Silane is added during synthesis in the present invention
Coupling agent, the siloxy on silane coupling agent have preferable reactivity for inorganic matter, the organic moiety in structure
There is preferable compatibility for organic matter.It therefore, can be with when silane coupling agent is between organic layer and inorganic layer
Form organic layer-silane coupling agent-inorganic layer binder course, inorganic material and organic material can be carried out merging well and
Connection.In the present invention, first by together with the monomer polymerization reactions such as silane coupling agent and butadiene, styrene, then it will need again
The inorganic raw material magnesium phosphate and magnesium silicate being attached are added in reaction system, are acted on silane coupling agent, will be organic
Layer with inorganic layer is good is combined together.
Meanwhile on the one hand the addition of emulsifier participates in emulsion polymerization, be conducive to generate that partial size is smaller and uniform cream
Micelle；On the other hand, after the addition of some inorganic raw materials, original emulsion system can be broken, and emulsion particle is demulsified, in
The organic matter containing siloxy is combined with inorganic matter and gradually disperses under the action of stirring on the strand of portion's package.
And emulsifier can be present in system with free state, system is played reduce surface tension, increase the lubrication of storeroom with
And provide certain plastication.
Polymer after demulsification is agitated, action of soaking can be very good to be dispersed between inorganic material, these dispersions
Polymer in composite material in use, due to composite inner moisture evaporation, the water molecule layer between polymer constantly subtracts
Few, the strong intermolecular force (such as intermolecular hydrogen bonding) between polymer can promote polymer molecule to link together,
A firm polymer network is formed, wherein by inorganic material package, plays the role of adhesive.
In addition, composite material use when, in outermost polymer can it is agglomerated together formation one layer it is smooth
, fine and close, transparent polymer film, play waterproof, moisture resistance and the effect of heat preservation.
