Water-resistant type cloud stone glue and its preparation and application
Technical field
The invention belongs to adhesive for building technical field, and in particular to a kind of water-resistant type cloud stone glue, and further relate to it
Preparation and application.
Background technology
Cloud stone glue is widely used in bonding between all kinds of stone materials or for such as crack of stone surface, hole, sand holes
Etc flaw fill up and the repairing to stone material mark of break.
Cloud stone glue has point of one pack system and bi-component, cloud stone glue such as CN102146571B (cloud stone glue and its system of one pack system
Standby technique) and CN103571422B (a kind of cloud stone glue);The typical document of the cloud stone glue of bi-component disclose as
CN101735760A (a kind of cloud stone glue and preparation method thereof).Coagulated because bi-component cloud stone glue has relative to one pack system cloud stone glue
The strong point such as glue speed is fast, hardening time is short and adhesive strength is high, thus bi-component cloud stone glue is generally used at present.
The component A of bi-component cloud stone glue in prior art raw material is mostly:Unsaturated polyester resin, polymerization inhibitor, rush
Enter agent, filler and thickener;Component B raw material is mostly curing agent, plasticizer, filler and thickener, this can be seen in foregoing
CN101735760A.In use, component A is well mixed by a certain percentage with component B.
Pass through the reading to being not limited to patent document exemplified above:Why hot in cloud stone glue raw material people are
Inner feelings in using unsaturated polyester resin, be because unsaturated polyester resin main chain on have substantial amounts of ester bond and double bond, with compared with
High reactivity.But the weakness of unsaturated polyester resin is not often people's enough attention, so-called weakness is as shunk
Rate is big, wet-heat resisting and resistance to acids and bases are poor, the ester bond easy fracture particularly under long-term hygrothermal environment, exactly in view of this factor, contains
The cloud stone glue for having unsaturated polyester resin is usually not used for the structural bonding of construction material, such as because losing toughness and elasticity
And dry-hang stone is cannot be used for, so as to have impact on the expansion of its purposes to a certain extent.
