Description
Technical field
The invention belongs to U.S. to stitch glue technical field, is related to a kind of U.S. seam glue of antibacterial.
Background technology
With the development of society, various New Building Materials emerge in an endless stream, ceramic tile turns into China ground and wall decoration
One of principal item of material, application are more and more wider.In fitment process, in order to fill up existing gap between ceramic tile,
U.S. seam glue generally can be all filled between these gaps, so either kitchen or toilet, the hall that even business is fitted up
The figure that will have U.S. seam glue occurs.
Be presently used for filling the gap filler in this gap have the U.S. seam glue of common cement-base gap filler, one-component acrylic and
The U.S. seam glue of reactive resin.Common cement-base gap filler is using white cement, powdered whiting and re-dispersible glue powder as raw material system
For what is formed.After cement base gap filler uses a period of time, stain resistance is poor, is easily made it by white by pollutions such as dust, oil smoke
Blackening, and easy mould growth, influence domestic environment.U.S.'s seam glue is the upgrading products of gap filler, mainly by polymerizable aqueous
Thing emulsion and high-grade pigment composition, such as the U.S. seam glue of acrylic.But the U.S. seam glue wearability of acrylic is poor, not stain resistant,
Loss of properties on aging.U.S. seam glue based on epoxy resin can thoroughly solve problem above, not have accumulation of salt in the surface soil phenomenon, construction party
Just, cold curing, resistant, scrubbing resistance.But epoxide-resin glue is a kind of two component, need component A and B groups when in use
Divide and be used cooperatively, construction is inconvenient.
However, existing U.S. seam glue and gap filler are more the performances such as concern flintiness, rub resistance, color be beautiful, it is right
Suppress gap anti-microbial property aspect Shortcomings.So as to, existing U.S. seam glue and gap filler suppress gap antibacterial effect and unobvious,
Indoor microorganism pollution source can not be reduced and reduce its injury to human body.
