Its main raw brief introduction is as follows:
Epoxy refers to and in organism, in the middle of carbochain, adds Sauerstoffatom, forms a trilateral such as two carbon of modal oxyethane (CH2-O-CH2) also connect together.Resin can form three kinds of water-dispersion forms by different Water-borne modification approach: 1. water-soluble; 2. micella decentralized; 3. emulsion.Epoxy resin is from as thermoplastic linear structure, the solid-state liquid state that becomes after being heated, and high viscosity becomes low viscosity, only has with solidifying agent and is used in conjunction with and just has practical value.Therefore water-borne epoxy systems should comprise aqueous epoxy resins and aqueous epoxy curing agent, and same, they can form three kinds of water-dispersion forms by different Water-borne modification approach respectively.Therefore water-borne epoxy systems has more Selection and Constitute (having in theory the form families of 9 kinds), but has also increased selection difficulty.In actual application, by adding a large amount of color stuffing, auxiliary agent etc., raising water-borne epoxy systems application performance has also been covered the even major defect of deficiency of water-borne epoxy systems simultaneously simultaneously, and this will increase more uncertain factor and complicacy.
No matter select aqueous epoxy resins and the aqueous epoxy curing agent of which kind of form, the water-borne epoxy systems finally with actual application value is a kind of heterogeneous structure that disperses, by aqueous epoxy resins, aqueous epoxy curing agent, the heterogeneous composition such as water, its membrane formation mechanism is different from general polymer emulsion as the film forming of the ACRYLIC EMULSION (film forming of condensing, physical process), simultaneously also incomplete same with the film forming of solvent type epoxy, in solvent type epoxy system, epoxy resin and solidifying agent are all dissolved in organic solvent with molecular form, the system forming is homogeneous phase, curing reaction carries out between molecule, thereby curing reaction carries out more completely, the cured article forming is also homogeneous phase.
Water-base epoxy is heterogeneous system, epoxy resin and solidifying agent are dispersed in water with disperse phase form, crosslinking curing process is the internal divergence crosslinking reaction process that interpenetrates between particulate in the process of moisture evaporation, and therefore the state of cure of water-base epoxy depends on following four factors:
A) consistency: the consistency of aqueous epoxy resins and aqueous epoxy curing agent is better, is more conducive to solidifying agent particulate and the mutual internal divergence of epoxy resin particulate, is conducive to the carrying out of curing reaction;
B) particle diameter: particle diameter hour, reaches state of cure more completely thereby aqueous epoxy resins and aqueous epoxy curing agent dispersed phase particles can be interpenetrated to kernel more fully;
C) hydrophile-lipophile balance value: the hydrophile-lipophile balance value of aqueous epoxy resins and aqueous epoxy curing agent approaches, in water, reach the consistent steady state that coexists, if differed greatly, the component that wetting ability is stronger can be gathered in water gradually, thereby causes resin-phase and solidifying agent to be separated;
D) degree that is uniformly dispersed: under the state of multi-phase separation, only have by certain mechanical agitation, resin-phase could be uniformly distributed in water mutually with solidifying agent.
Composite Portland cement (abbreviation complex cement), wherein 425 and No. 525 cement divide two types by early strength.Each age strength of each label, all types of cement must not be lower than following table numerical value:
Polymer clay cohesive force is large, impervious good, water-fast, resistance to cracking, weathering resistance are strong, surfacing, hardened ground intensity are high, water resistance excellence; When levelling construction technology, have good mobility, gravity flow levelling, does not need to vibrate; Firm, the soft network structure of Ji mutually of its uniqueness makes it have very strong impermeability and good construction adaptability.Can be at facade, on dry or moist basal plane, carry out operation, can be used as civilian and industrial building waterproof layer, interfacial agents, thermal insulation layer, also as moistureproof crack-resistant layer and tack coat, also can be used for wall face, external wall outer insulation anti-seepage and anti-crack layer, also can be used for ceramic tile, vitrified tile, the stickup of the stone slabs such as marble and (be a kind of ground construction technology by doing water-based self-flatting ground making level layer after certain proportioning dilute with water, it is the fluent meterial that many materials mix with water, pour into behind ground, this material can be taken advantage of a situation mobile according to being uneven of ground, Automatic Levelling is carried out in ground, and dry very soon, ground after solidifying can form smooth, smooth, seamless new basic unit).And coating is thin, consumption is few, intensity is high, technique is simple and quick, and the thickness of coating can regulate according to actual needs voluntarily, and waterproof, stickup, levelling only need a procedure.Construction costs is low, construction quality good, not only cost-saving the but also reduction of erection time.
