Description
Technical field
The present invention relates to building material technical field, refers in particular to a kind of high rigidity double-component waterborne polyurethane terrace and applies
Material.
Background technology
With the high speed development of economy and construction industry, floor coatings are promoted to enter prosperity and development period, while people couple
The requirement of floor coatings is also higher and higher.In the prior art, epoxy resin is as the resinous material for being applied to terrace earliest
Technology most it is ripe be also proportion maximum kind.
Resinae floor coatings major advantage is that hardness is high, resistance to acid and alkali is good.However, have a disadvantage in that：Because of epoxy resin
For rigid material so that its wearability, lower temperature resistance, resistance to surface scratch resistant are poor；Weatherability is poor, easy to aging, and service life is short.
Polyurethane floor coatings have preferable wearability and weatherability, but hardness is not compared with epoxies floor coatings
Foot.
The content of the invention
It is an object of the invention to provide the high rigidity two-component that the physical and chemical performances such as a kind of high hardness of paint film, wearability are excellent
Aqueous polyurethane floor coatings.
To reach above-mentioned purpose, solution of the invention is：
A kind of high rigidity double-component waterborne polyurethane floor coatings, by first and second liang of components by mass parts than 10:1 is uniformly mixed
Form, first component is the water-based aliphatic isocyanates of solids content 100%；Second component is made of following components by quality point：
Deionized water 7%-15%, modified high-molecular dispersant 0.5%-1.5%, multifunctional assistant 0.4%-0.9%, non-ionic profit
Humectant 0.1%-0.3%, pigment 1%-25%, filler 5%-30%, hydroxyl acrylic aqueous dispersion 40%-55%, inorganic addition
Agent 3%-7%, high-strength ceramic microballoon 2%-8%, polyethers defoamer 0.3%-0.5%, BIT class preservative 0.2%-
0.3%th, polyurethanes thickener 0.5%-2.5%.
Further, hydroxyl acrylic aqueous dispersion is that the trade mark of Beyer Co., Ltd's production is XP2542 products, is hydroxy acrylic acid
Dispersion, solid content are 50 mass %, and hydroxyl value content is 2.7-3.0 mass %.
Further, inorganic additive is that the trade mark of Van Baerle companies production is 330 products of INOCOT, with potassium silicate
Based on inorganic additive, solid content is 29.5 mass %.
Further, modified high-molecular dispersant is that the trade mark of Kyoeisha Chemical Co., Ltd.'s production is FLOWLEN G-
700AMP products, are a kind of 2-amino-2-methyl-1-propanol salt of hydroxyl polymer-containing modifier, and solids content is 40-50 matter
Measure %.
Further, non-ionic wetting agent is that the trade mark of Clariant Corporation is 070 products of LCN, is a kind of alkyl polyoxy second
Alkene ether, substance content 100%, HLB value 13.
Further, high-strength ceramic microballoon is that the trade mark of 3M companies is W-410 products, is a kind of high intensity, inertia, heavily fortified point
Firmly, fine spherical particle, compression strength are more than 413.41MPa.
Further, filler is ultra-fine synthesis blanc fixe and/or ultrafine mica powder.
Further, pigment is carbon black, in rutile type titanium white, iron oxide red, iron oxide yellow, dark green, phthalocyanine blue
It is one or more of.
Further, BIT classes preservative is that the trade mark of Troy company production is K10N products, is a kind of without formaldehyde and molten
The benzoisothiazolinone class preservative of agent.
A kind of high rigidity double-component waterborne polyurethane floor coatings preparation method, comprises the following steps：
First, it is divided into by quality：Deionized water 7%-15%, modified high-molecular dispersant 0.5%-1.5%, multifunctional assistant
0.4%-0.9%, non-ionic wetting agent 0.1%-0.3%, pigment 1%-25%, filler 5%-30%, hydroxy acrylic acid point
Granular media 40%-55%, inorganic additive 3%-7%, high-strength ceramic microballoon 2%-8%, polyethers defoamer 0.3%-
0.5%th, BIT classes preservative 0.2%-0.3%, polyurethanes thickener 0.5%-2.5%, are equipped with second component；
2nd, in whipping process, deionized water, modified high-molecular dispersant, multifunctional assistant and non-ionic are sequentially added
Wetting agent, and stir evenly；
3rd, stirring adds pigment and filler in material made from step 2, after with 1500 revs/min stir 10 minutes, so
Rotating speed is improved afterwards to 3000 revs/min of high speed dispersions 40 minutes, and semi-finished product are made；
4th, semi-finished product made from step 3 are moved into another reaction unit, hydroxyl is sequentially added under 400 revs/min of stirrings
Acrylic acid dispersion, inorganic additive, high-strength ceramic microballoon, polyethers defoamer and BIT class preservatives, stir 10 minutes extremely
After obvious bubble, polyurethane thickener is added, is further continued for stirring 15 minutes；
5th, the filter-cloth filtering by material made from step 4 with 120 mesh, up to high rigidity double-component waterborne polyurethane terrace
The second component of coating；
6th, second component and the water-based aliphatic isocyanates of first component are pressed into mass parts than 10:1 proportioning is made after mixing
Double-component waterborne polyurethane floor coatings.
After using the above scheme, the main composition in coating second component of the present invention be by hydroxyl acrylic aqueous dispersion resin,
What inorganic additive and functional stuffing three were formed, each of which has the advantages that specific：One hydroxyl acrylic aqueous dispersion is
The main part of film forming matter, its hydroxyl is based on being up to 3.3 mass % containing content admittedly, with first component aliphatic isocyanates polymer
In reactive group occur polycondensation reaction, crosslinking film forming.There is higher crosslink density after reaction, it is crisscross to form chemical chain
Space net structure so that the physical and chemical performance such as hardness of film, abrasion resistance significantly improves.It is organic that any volatility is not contained wherein
Thing and crosslinking film forming procedure need not add the high boiling solvents such as coalescents, can also meet environmental protection requirement；Secondly inorganic addition
Silicate component brushing in agent can penetrate into inside basic unit in basic unit and crosslink reaction with the free calcium in cement matrix,
Insoluble amorphous state hydrated calcium silicate is generated, so as to greatly improve the attachment between the hardness of paint film and basic unit and paint film
Power.At the same time because it can form the porous coating of porous steam rather than the coating of densification, make the exchange current of paint film inner air and outer air
It is logical to be possibly realized, reduce because humidity causes the possibility of film defect；Thirdly the white that functional stuffing is average grain diameter 15um is high
Strength ceramic microballoon, its compression strength is minimum to can reach 413.41MPa, can effectively be lifted hardness of paint film, wearability with it is corrosion-resistant
Property, while unlike the filler of other irregular shapes, high-strength ceramic microballoon be it is uniformly perfect spherical, can be as the steel in bearing
Pearl equally rolls, therefore reduces the viscosity and inherent strain of product, so making the final product stream property moved outstanding, and does not allow
