Abrasion-resistant powder is silicon-dioxide, magnesium oxide, ferric oxide or calcium oxide.
The relevant components description of coating of the present invention is as follows:
Resins, epoxy---according to from the cleanly requirement of level ground coating of levelling, should have ambient cure, high cohesive force, strong physical strength, chemical proof, good electric property as the Resins, epoxy of film forming matter.
Solidifying agent---for from levelling level ground coating cleanly, reach and once construct into thickness, short-term is solidified the requirement that the back obtains high cohesive force, and common solidifying agent can't meet the demands, and should adopt modified firming agent, makes solidification process not have free ammonia and folds.
Thinner---from levelling cleanly level ground coating one-pass film-forming thickness reach 1-3mm, for preventing that the non-active solvent volatilization from producing paint film defect, selected reactive thinner for use, make nothing (volatilization) solvent based coating, simultaneously also meet environment protection requirement, improve execution conditions.
Auxiliary agent---from levelling cleanly level ground coating require high to the levelling property of filming, particularly under the thick film condition, should make the abundant levelling in the limited time of filming, require in the thick film bubble to discharge rapidly again and face does not stay defective, therefore, the selection of auxiliary agent such as flow agent, defoamer and consumption are the factors of crux very.On the one hand this type of auxiliary dosage increase can reduce the surface tension of filming, levelling that helps filming and froth breaking, and this analog assistant too much adds affiliation and causes and the bonding between resin, thinner and filler is had a negative impact immiscible thing on the other hand.It must be to guarantee fineness through dispersion grinding that multiple pigment, filler are arranged in this coating, improves dispersion efficiency, has also added dispersing auxiliary.
Toner---available pigment adds with work in-process pigment paste (slurry) form, guarantees that coating is uniformly dispersed and color and luster is attractive in appearance.
Abrasion-resistant powder---as filler, increase the wear resistance after the coating film forming, in addition, no matter from the still performance after the film forming of workability, the viscosity of coating is vital.Wish the solids content height of coating on the one hand, help self-leveling terrace coating like this and once obtain big thickness; Do not wish again that on the other hand viscosity is too high, unfavorable construction.Found through experiments, influence changes less the abrasion-resistant powder add-on to dope viscosity.For self-leveling floor coating, its maximum advantage just is that a construction area is big, integral seamless, and this just has higher requirements to the linear shrinkage of filming, and the add-on of abrasion-resistant powder can obviously reduce the linear shrinkage of filming, and improves the paint film quality.
