Water-resisting type cloud stone glue and preparation and application thereof
Technical field
The invention belongs to adhesive for building technical field, be specifically related to a kind of water-resisting type cloud stone glue, and relate to its preparation and application.
Background technology
Cloud stone glue is widely used in bonding between all kinds of stone material or fills up for the flaw in such as crack, hole, sand holes and so on to stone surface and repairing to stone material mark of break.
Cloud stone glue have single component and two-pack point, the cloud stone glue of single component is as CN102146571B (cloud stone glue and preparation technology thereof) and CN103571422B (a kind of cloud stone glue); The typical document of the cloud stone glue of two-pack is open as CN101735760A (a kind of cloud stone glue and preparation method thereof).The strong point such as have that gelation rate is fast, set time is short due to two-pack cloud stone glue relative to single component cloud stone glue and bonding strength is high, thus generally uses two-pack cloud stone glue at present.
The raw material of the component A of the two-pack cloud stone glue in prior art is mostly: unsaturated polyester resin, stopper, promotor, filler and thickening material; The raw material of B component is mostly solidifying agent, softening agent, filler and thickening material, can be seen in aforesaid CN101735760A to this.During use, component A is mixed by a certain percentage with B component.
By known to the reading of the patent documentation being not limited to exemplify above: why people hanker after adopting unsaturated polyester resin in cloud stone glue raw material, be because the main chain of unsaturated polyester resin has a large amount of ester bonds and double bond, there is higher reactive behavior.But the weakness of unsaturated polyester resin is not often people's enough attention, so-called weakness is as large in shrinking percentage, wet-heat resisting and resistance to acids and bases poor, particularly ester bond easy fracture under long-term hygrothermal environment, just in view of this factor, cloud stone glue containing unsaturated polyester resin can not be used for the structural bonding of material of construction usually, such as because losing toughness and elasticity and dry-hang stone can not being used for, thus have impact on the expansion of its purposes to a certain extent.
