Application of the calcium carbonate in powdery paints：（1）The filler of high-gloss paint product can be made.（2）Semigloss coating product, Calcium carbonate preparation can be typically directly added into, it is cost-effective without adding delustering agent.（3）This, can be with titanium as the inorganic filler of white White powder is used cooperatively, and reduces cost.（4）With respect to other fillers, calcium carbonate is best suited for some and requires the low ring of content of beary metal Protect product.（5）Coating powder utilization and spray area can be improved, it is obvious especially in mixed powder.（6）Play skeleton function, Film thickness can be increased, improve coating abrasion performance and durability.（7）Metope is fine and smooth after spraying, and wall base pore structure form is good, only Change air and hygroscopicity is big.

Coral powder is process by residuum or discarded sweet viburnum and coral sand.Coral sand originates from Hainan Province, resource It is abundant.Coral powder is the shell of coral polyp secretion, and the chemical composition of coral is mainly CaCO3 90% or so, is solved with crystallite side Stone aggregate, which is formed, to be present, and hardness is 3 ~ 4.0, and degree density is 2.6 ~ 2.7g/cm3, opaque.The trace quantity mineral enriched in coral An important factor for matter is its huge efficiency, because it is easy to absorb and do not produce constipation effect, and also have very high Medical value, there is hemostasis and drive the function of heat, skin maintenance, the effect of blood circulation-activating eyesight-improving.

The choice direction of coral powder function interior trim wall material filler and functional characteristic：

Talcum powder（Also known as hydrated magnesium silicate）

Greasy feeling is touched with for white or off-white color, fine, without grittiness powder, hand.It is odorless, it is tasteless.Characteristic：Talcum has lubrication Property, it is anti-stick, help stream, fire resistance, acid-resisting, insulating properties, fusing point it is high, chemically torpescence, covering power well, softness, good luster, The excellent Wuli-Shili-Renli system approach such as strong adsorption force, because the crystal structure of talcum is in stratiform, easily squama is split into so having The trend and special slip of piece, can lower its insulating properties if Fe2O3 content is very high.The main work of talcum powder With：Influence of the talcum powder to coating property is controlled by its structure type or mixture type, average grain diameter and particle diameter distribution.Cause It is substantially threadiness or sheet for most of talcum powder products, so its classification is also based on this.Fibrous talc Outdoor durable is best, but mobility is poor in coating, and smooth coating degree is also insufficient.It is excellent that platy talc can assign coating Brush, levelability, coat film flatness and gloss retention, can also assign coating " lubrication " performance.Granular talcum powder quantity is seldom, But there is best adhesiveness and grindability, this indicates that its seal coat or surface coating material for being applied to polish.

The dry powder brightness of talcum powder is high, and the form and aspect in water-based and oleaginous system are preferable.Talcum powder applies in all liq All easily moistened in material and scattered, appropriate stirring is only needed in dispersion process.Talcum powder has excellent suspension in coating Property, it also can help to other pigment in system and keep suspended state.

Talcum powder is applied in a variety of industrial coatings, can improve the precipitability of coating, the mechanical force of film and re-coating Property.Talcum powder has lubricity, and fire resistance, acid-resisting, insulating properties, fusing point is high, chemically torpescence, and covering power is good, soft, light Damp degree is good, the excellent physics such as absorption affinity, chemically, because the crystal structure of talcum powder is in stratiform, so with easy point The trend of scale and special lubricity are cleaved into, can lower its insulating properties if Fe2O3 content is very high.

The effect of talcum powder is one of coating additive, and a small amount of addition can increase substantially coating and performance, moreover it is possible to change Kind film performance, helps to realize the personalization of commodity.Coating film should possess a variety of performances and special efficacy, expire Sufficient these requirements, it is necessary to coordinate the key between various characteristics.The spy of the primary raw materials such as resin, pigment and solvent is fully grasped for this Point, it is the difficulty that coatings industry needs to overcome.The properties such as the mobility of coating, the dispersiveness of pigment, levelability and clarity, close It is to painting effect, is the key for improving added value of product using additive.But if application method is improper or addition mistake It is more, opposite effect can be caused.

Because talcum powder has lubricity, anti-stick, helps stream, fire resistance, acid-resisting, insulating properties, fusing point height, does not live chemically The excellent Wuli-Shili-Renli system approach such as bold and vigorous, covering power good, softness, good luster, strong adsorption force, the main body of application in coating It is now：In coating, talcum powder can play skeleton function, the paint film that reduction manufacturing cost improves coating simultaneously is hard as filler Degree.The stabilization of shape of product can mainly be increased, increase tensile strength, shear strength, flexing intensity, the intensity of pressure, reduce deformation, Extension rate, thermal coefficient of expansion, the features such as whiteness is high, epigranular dispersiveness is strong.

Grey calcium

Grey calcium alias calcium hydroxide.A kind of air hardening cementitious materials, applied to can be improved in building coating water-resistant coating, Abrasion resistance, good leveling property.Sierozem power main component is Ca (OH)₂, CaO and a small amount of CaCO₃Mixture, be lime finishing Chemical product.

Sierozem power is added in coating, with the coating film forming of coating, calcium hydroxide（Calcium oxide becomes hydroxide after meeting water Calcium）Can be with the CO in air₂Reaction generates calcium carbonate crystal and produces intensity, and then can be provided in film for coating composition Certain caking property, and assign coating significant water resistance.The various building coatings produced using sierozem power as main active filler It is low with cost, the focus such as water-tolerant.

Bentonite

Application performance of 1 bentonite in coating

1.1 bentonites are as inorganic thickening agent

Thickener can increase the viscosity of coating, improve the rheological property of coating, and it is essential in the production of coating. Each coating has its requirement to rheological characteristic, for example, emulsion paint in storage stage, should have higher viscosity in favor of preventing Layering and precipitation；In the construction stage, external force of the emulsion paint by high-rate of shear, it is desirable to have relatively low viscosity, do not drag during brushing Brush, atomization is good during spraying, is splashed without drawing during roller coating.Shear and disappear after coating, viscosity is with recovering but should not be too fast, with foot Enough flow times.This just needs a kind of suitable thickener to change the viscosity of coating.Bentonite exists as inorganic thickening agent There is a certain degree of application in coating material production, its characteristic is that thickening effect and suspension are notable, and coating can be made to produce thixotropy, It is easy to store and constructs.The researchs such as Pat Hoontrakul (1988) find to add bentonitic coating, clipped effect masterpiece With rear, the time of viscosity recovery substantially shortens, and has fully demonstrated bentonitic thixotropy.He thinks to produce this special circumstances Reason is that bentonitic polar surfaces trigger to form the network structure of hydrogen-oxygen key connection, and this network structure is once formed, then by During to shear action, it can recover quickly.

The mechanism of action of the bentonite as inorganic thickening agent：Bentonite has strong absorptive, can adsorb 5 times of quality itself The water of left and right, volume increases after absorption, is expandable to several times to more than ten times of original volume, and form spawn and wrap painting Color stuffing particle in material, prevents particle from settling.It is cross-linked with each other with organic double compound, forms netted stereochemical structure, improves coating Suspension.

1.2 bentonites are used as suspension sagging inhibitor

Bentonite has good suspension and dispersiveness in aqueous medium.Bentonite can discharge charged particle in water and rise To the function of dispersant, the suspension of water paint can be improved, appropriate bentonite is added in building coating can make generation Coating is not easy to precipitate, be not easy to be layered, color is uniform, so as to improve the suspension stability of coating.Bentonite after organically-modified exists There is good dispersiveness, its sheet edge adsorbs the long-chain organic matter of oleophylic and had with paint vehicle good in solvent based coating Compatibility, while be distributed oxygen therein and hydroxyl group and can form the hydrogen bond with result of prevention, coating is turned into uniform Jelly simultaneously has certain viscosity, and then plays a part of preventing pigment sedimentation.Stirred when in the presence of extraneous shearing force When mixing, hydrogen bond is destroyed, and viscosity weakens, and coating has mobility again.

1.3 bentonites are used as additional adhesive

Bentonite carrys out very big caking property with water mixed zone, and this characteristic is from many-side, as bentonite is hydrophilic, particle is thin Small, plane of crystal electric charge variation, the scrambling of particle, hydroxyl and water form hydrogen bond, the absorption to micro-content organism and more The poly- attached form of kind forms colloidal sol etc..Because bentonite has preferable caking property and covering power, being introduced into building coating can generation For part base-material and other fillers, so that product cost reduces.

1.4 bentonites are as auxiliary rheological agents

The sagging and levelling of coating are two conflicting phenomenons, it is necessary to which an excellent auxiliary rheological agents, make sagging and levelling two Individual performance obtains balance.When coating is stored, auxiliary rheological agents are internally formed a loose structure at it, after construction, receive outer Power, internal structure are easy to levelling by coating is destroyed, and slowly recover loose network structure again to certain phase wet film inside, and have Beneficial to preventing sagging.

Organobentonite has surprising adsorption swelling ability and thixotropic effect in a solvent, and it is used for as auxiliary rheological agents The production of coating, construction, storage, film forming each stage, assign structural viscosity of the coating under low shearing speed.It is noticeable It is that organobentonite has adaptability to various different solvents, thickening properties are widely different in different solvents.Organobentonite Suitable for organic solvents such as polyester, alkyd paint, chlorinated rubber, oxidized asphalts, dosage is generally the 0.2%~2.0% of system total amount. Li Hongmei writes text in chloro-sulfonated polyethylene anti-corrosive coating and chlorinated rubber anticorrosive paint using the production of Tianjin organic pottery clay factory For organobentonite as sample made from auxiliary rheological agents at a temperature of 23 DEG C or so, the viscosity of coating respectively reaches HG/ T2661-1995, HG/T2798-1996 standard, and coating good leveling property, no sag phenomenon, and extend the pigment sedimentation time.

Application of 1.5 bentonites in other coating

Bentonite can be used as the raw material of water-repellent paint.Though bentonite has good water proofing property, state, nothing itself are in granular form Cohesiveness, thus need to select non-aqueous media that clay is made with bentonite, and the medium will have certain water proofing property.Bentonite emulsifies Bentonite and pitch are exactly mixed to prepare water-repellent paint by asphalt waterproofing paint, and it is mainly used in roof waterproof, can improve work Effect 50%, construction costs 40% is reduced, and substantially improve the working condition of worker, improve waterproof effect.It is reported that brushed on roofing Bentonite emulsified asphalt water-proof paint, service life can be increased for many years, the roofing constructed not yet damages for 35 years.

The advantages of 2 bentonites are applied in coating

Existing research work shows that bentonite, which is used in coatings industry, good performance, is summarized as follows：

2.1 bentonites can increase the denseness of coating, improve suspension, improve anti-settling performance.

2.2 bentonites can improve the scrub resistance and water resistance of film.

2.3 bentonites can improve the covering power of coating, can reduce the dosage of base-material and substitution part pigment, drop in coating The cost of prepared paint.

2.4 bentonites have cold resistance, can still construct as usual in the winter time.

2.5 bentonites have good caking property, dilatancy, adsorptivity, plasticity, dispersiveness, lubricity, cation Exchangeability.There is great suspension after being exchanged with other alkali, lithium base, have excellent decolourising property again after acidified processing Deng.Therefore it can be made into various binding agents, suspending agent, adsorbent, decolorising agent, plasticizer, catalyst, cleanser, disinfectant, increasing Thick dose, scale remover, detergent, filler, reinforcing agent etc..Its chemical analysis quite stable, it is described as " omnipotent stone ".

Silica flour
