Sealant compositions and the application in the auto-flowing floor product thereof
Technical field
The invention belongs to the encapsulant field, relate to a kind of high performance sealant compositions, be applicable to the cement matrix or the loose structure that generally use in SLF (auto-flowing floor) product.The invention still further relates to the application of this sealant compositions in the auto-flowing floor product.
Background technology
The SLF product is a cement-based material, and it will form the material of porous sclerosis after curing and drying.For prevent that it is aging, wearing and tearing and because of leakage causes long pollution, the sealant that need can be used in extensive use provide have anti-scratch property, final application that pollution resistance and good anti-household liquids are polluted.
Organic solvent based sealer is believed to deeper infiltrate in the hole, and waterproof well.But its organic solvent content (accounting for the 50-80% of total formulation weight amount) is a kind of threat for environment and health.And the water-base emulsion sealer is safer usually, cheapness and environmentally friendly.
Yet, though change the benefit that aqueous composition can bring health and safety into from the organic solvent based composition and use thereof in packaging,, the water-base emulsion composition also needs to satisfy, even exceeds the performance standard that solvent-based compositions has.
U.S. Patent application US 5191002A discloses a kind of protective floor maintenance system, and it utilizes low zinc or phosphate prescription to reduce performance is kept in the influence of environment and the protective floor that provides usefulness.
European patent application EP 1371698A1 discloses and a kind ofly has been used to suppress water and infiltrates and comprise the application composition of cementitious material that average grain diameter is the polymer/nanoparticle of 1-50nm.
But the method for above-mentioned prior art only relates to the partial properties of sealant, can not satisfy the comprehensive demand of SLF product.
Therefore, this area presses for the coating preparation of developing a kind of SLF of being applied to product, and it can provide anti-household liquids, improves durability, the scraping of the capable traffic of contragradience and pollution and reduce performance to the needs of maintenance.
Simultaneously, this area also presses for the method that a kind of performance of estimating sealant changes along with pedestrian traffic of developing.Because that these sealants normally clean, colourless, so be very difficult to determine the degree of wearing and tearing.This method can help to determine sealant which point be worn and need and repair.In addition, this method can also be distinguished the difference of different sealing layer.

Use the method for embodiment 1, the HY-1803 organic titanium huge legendary turtle compound (deriving from Jessica chem. company) of 2 weight portions is dissolved in the deionized water of 55 weight portions.Then, this mixture is added in the epoxy functionalized acrylic acid ester emulsion of 100 weight portion HD2535 (deriving from HUA JIN SI Trading company).The DALPAD A of Bubble Breaker 3056A siloxy group defoamer, 2 weight portions that adds Henkel 5040 (by the carboxylate of acrylic ester copolymer), 1 weight portion of WE-618B3 polymer wax emulsion (deriving from Sino-wax company), 2 weight portions of 5 weight portions in this mixture is as coalescents (deriving from Dow Chemical company) and 2 weight portions
The pre-composition of polyfunctional crosslinking agent (deriving from Bayer Material Science company).Said mixture is used as the hole packed layer in sealant compositions.
As the top coat in the sealant compositions, the HY-1803 organic titanium huge legendary turtle compound (deriving from Jessica chem. company) of 3 weight portions is dissolved in the deionized water of 80 weight portions; Then, the acrylic emulsion (deriving from Tianyin Chemical company) that this mixture is added the water base carbamate-functional of 100 weight portion TC 106F; The MPF5003 polytetrafluoroethylene (PTFE) wax emulsion (deriving from Joule wax company) that in this mixture, adds 8 weight portions, the Henkel 5040 of 3 weight portions (by the carboxylate of acrylic ester copolymer), the Bubble Breaker3056A siloxy group defoamer of 1 weight portion, the DALPAD A of 3 weight portions is as coalescents (deriving from Dow Chemical company), the polyether-modified dimethyl silicone polymer of the BD-3033 of 3 weight portions makes as the pre-composition of F-0082 polyfunctional crosslinking agent (deriving from Yoowe chemical company) of anti-scratch liniment (deriving from Baldsilicone company) and 3 weight portions.
Embodiment 3
Use detects the sealant compositions among the method evaluation embodiment 1 that weares and teares on the SLF product.Four coatings (comprising two hole packed layer coatings and two top coats) of sealant compositions are coated on the SLF floor.Be exposed under the current load of height in the supermarket.Main load resource flows from client.After 2 months, obtain result as shown in Figure 1.
Embodiment 4
Use the sealant compositions identical, be exposed in the reciprocal back and forth equipment in the laboratory with embodiment 3.Main source of wear is knocked from drift.After 8 hours, obtain result as shown in Figure 2.
Comparing embodiment 3-4 as can be known, for sealant compositions of the present invention, the different conditions that are exposed to wearing and tearing obtain the similar degree of wear.Therefore, the method for the wearing and tearing on the described mensuration SLF product can expand to the relevance between the practical application of setting up described sealant compositions and the quick evaluation test.
