Description
Technical field
The present invention relates to a kind of water based epoxy floor material and preparation method thereof, belong to building material field.
Background technology
Low volatile organic (VOC) content and high performance are two the important development trend of chemical building material that comprise coating, tackiness agent, water-resisting agent, floor material.Resins, epoxy has good tack, thermostability, chemical-resistant, insulativity and physical strength etc., makes it obtain at aspects such as building ground floor application, interface processing, waterproofing and leakage-stopping, grouting, mortar reinforcement to use widely.But Resins, epoxy commonly used is water-insoluble, and only being dissolved in aromatic hydrocarbons, ketone and alcohols etc. has solvent, and organic solvent not only price is more expensive, and have volatility, environment is polluted, limited its large-scale application in coating, adhesive industry.
For this reason, aqueous epoxy coating arises at the historic moment, and along with the increasingly stringent to environmental protection requirement, does not contain volatile compound (VOC), or low VOC or the system that do not contain air pollutant (HAP) have become the research direction of type material.Develop aqueous epoxy coating since the seventies in 20th century abroad, its performance can reach the level suitable with the solvent-borne type epoxy coating.
Take a broad view of that the Water-borne modification of epoxy resins technology of having reported at present can be divided into emulsion process and two kinds of methods of salt forming method are (1. quickly old: double-component aqueous epoxypaint, polymer circular, 2002 (6), P63-70; ) 2. Zhang Li wait " progress of aqueous epoxy resin systems " coatings industry, 2002 (8), P28-30), emulsion process is direct emulsification of Resins, epoxy or letex polymerization; Salt forming method is the resin with epoxy resin modification Cheng Hanfu acid or rich base groups, uses in the acid of small molecular weight or the alkali again and salify.
The development of external epoxide terrace technology has three phases: the one, and solvent-free system, the 2nd, water based epoxy system.Entered most advanced product in developed country at present, promptly third generation water based epoxy was a a progressive step again than former water based epoxy.(L.Fuchang?et?al，wo?020?72658)。
Summary of the invention
The object of the present invention is to provide a kind of new water based epoxy floor material and preparation method.
Specifically being made up of A, B two components of water based epoxy terrace provided by the invention is (wt%); The B component is a benchmark with A component 100%.
A component: (1), water-based sex change amine polymer 15-40
(2), dispersion agent 01-0.5
(3), defoamer 0.3-0.6
(4), pigment titanium white 0.5-20
(5), mill base 0.1-5
(6), filler 25-50
(7), auxiliary agent 0.2-0.3
(8), diluting solvent water surplus
The B component: (9), epoxy equivalent (weight) 190 liquid are stopped epoxy 8-20
The maximum difference of the present invention and other water based epoxy terraces is to make the sex change amine polymer of use and common solvent-free liquid epoxy compatibility to reach the complete aquation purpose of total system.Low viscosity sex change amine is the outstanding solidifying agent of water based epoxy floor material, because of it contains strong polarity amido, easily and water treatment, with respect to the then easier realization of sex change amine aquation of epoxy hydration technology, key of the present invention is the aquation of sex change amine polymer, uses with common liq epoxy compatibility in use with this material.
The trade mark that the dispersion agent that the present invention uses provides as the modest chemistry of moral is 902 dispersion agent.Defoamer is that the trade mark of Bi Ke chemistry (Byk) supply is 045 defoamer.The Byk333 auxiliary agent that auxiliary agent provides for the Bi Ke chemistry.Water-based sex change amine polymer is water base sex change amine of gas company or the vapour crust sex change amine that is provided by U.S. gas company or Ciba company.
Described filler or be barium sulfate or for quartz sand (SiO
2), described 190 liquid epoxies or be U.S. shell chemistry 828 trades mark, or be DOW Chemical DER331.Certain corresponding dispersion agent of home-made, defoamer also can use, but its effect is not as the trade mark of the present invention
In fact water base ring epoxy floor material provided by the invention offers with two components of A, B that the client uses.That is the A component is formed in (1)～(8) in the above-mentioned composition, and (9) are referred to as the B component.After the A component adds water and stirs during use the B component is slowly added, stir about can spray or roller coating behind the restir in 5 minutes.
The technical process of A component preparation as shown in Figure 1.
Component (1), (2), (3) added behind the water of total amount 6-10% high-speed stirring 5 minutes in above-mentioned component ratio batching, add (4) (6) (7) and aqueous solvent then, this moment, the consumption of water was the amount that total water add-on is deducted 6-10%, through the sand mill sand milling, add auxiliary agent at last, after the high-speed stirring, add the different colours mill base according to customer requirement, again through high-speed stirring, packing.
Wherein 1, (1) (2) (3) and suitable quantity of water be slowly to be added to successively in the stainless steel vessel, through 300～500 rev/mins of high-speed stirring.
2, the back that stirs adds (4) (6) and suitable quantity of water high-speed stirring 5 minutes to mixing;
3, sand milling is advisable with horizontal sand milling, and it is following for good that fineness is controlled at 45 μ m;
4, still need to stir behind the adding auxiliary agent;
Water base floor material principal character provided by the invention is other oiliness terraces or previous elder generation's property terrace relatively, lists in table 1.
| Oiliness | Previous water-based | The present invention | |
| System | Oiliness contains organic solvent | Water-base epoxy and polyamides | Water-based sex change amine, nothing has |
| Amine contains organic solution | The machine solvent | ||
| Smell | The intense stimulus smell | Pungent odour is arranged | Odorlessness almost |
